Re: Any sucess building Tuscany in eclipse using m2eclipse (maven) and svn plug-ins ?

2006-11-08 Thread Dan Murphy

Thanks all,
Seems like the general opinion is that building with maven in eclipse
(m2eclipse is meant to do this) seems like a path less well trodden
I've got the external svn, mvn eclipse, import method working so I guess
I'll just leave the maven building to the command line... same 'cos
m2eclipse claims to sort out the dependencies and work with maven repos etc
plug give some context assist for editing poms - just doesn't seem to work
with Tuscany :(

DAS as a POJO service

2006-11-08 Thread Kevin Williams
I just committed the nice DAS - POJO service contribution from Luciano 
and have a few comments/discussion points:


Here is the service API:

   /**
*
* @author lresende
*
*/
   public interface DASService {
  
   public void configureService(InputStream configStream) throws

   DASServiceException;
  
   public DataObject executeCommand(String commandName, Vector

   commandArguments) throws DASServiceException;
  
   public DataObject execute(String adHocQuery, Vector

   commandArguments) throws DASServiceException;

   public void applyChanges(DataObject graphRoot) throws
   DASServiceException;
   }



We need to find a way to replace the configureService API with an SCA 
pattern for providing config information.  Amita has solved this with 
the DAS-container contribution but I assume there is a pattern for POJO 
services too.


We should avoid checked exceptions.

Could the Vector argument list be replaced with a List?

I think Apache discourages the use of the @author tag

Re: Declarative DAS, was Re: Modeling the RDB DAS in SCA

2006-11-08 Thread Amita Vadhavkar

Hello Kevin , Luciano,
Thanks a lot for all your suggestions and looking forward to have a IRC chat
with you.
I am proposing 9th Nov 5.30 a.m. IST (8th Nov 4.00 p.m. PST) for approx. 1
hr.
Please join the chat and we all can discuss -
1) what we are trying to provide - service, container
2) what all features can be provided
3) any high level design suggestions ( sim. to Kevin's latest reply )
4) any other suggestions
5) we can try to come up with a list of work items
This will be very helpful in getting a clear picture of what all can be done

in SCA (as well as DAS) domain for our current work.

Amita

Hello Amita,

This looks promising.  I notice your test case uses explicit updates and
inserts.  While this is supported by the DAS it is not the preferred
usage which is to allow the RDB DAS to generate the CUD statements from
the SDO change history.  Could you modify the example to read a data
graph and then post the changes back via applyChanges?  Maybe the
equivalent of this simple test from the DAS test suite:

   public void testReadModifyApply4() throws Exception {

   DAS das = DAS.FACTORY.createDAS(getConfig(CustomerConfig.xml),
getConnection());
   // Read customer with particular ID
   Command select = das.getCommand(getCustomer);
   select.setParameter(1, 1);
   DataObject root = select.executeQuery();

   DataObject customer = (DataObject) root.get(CUSTOMER[1]);

   // Modify customer
   customer.set(LASTNAME, Pavick);

   das.applyChanges(root);

   // Verify the change
   root = select.executeQuery();
   assertEquals(Pavick,
root.getDataObject(CUSTOMER[1]).getString(LASTNAME));

   }

Also, this service interface seems difficult to work with since command
identifiers and argument values are encoded in the params Vector

   public interface CustomersOrdersService {

   void execute(Vector params);
   DataObject executeQuery(Vector params);
   void applyChanges(Vector params);
   DataObject executeAdhoc(Vector params);//adhoc query implementation

   DataObject getAllCustomers(Vector paramsList);

   }

Do you think it possible to implement something like the following
interface:

   public interface DynamicRDBDASService {

   DataObject execute(String commandName, List params);
   DataObject executeAdHoc(String queryString, List params);
   void applyChanges();
   }

The name is kind of long (suggestions welcome) but, I think this
interface could be generic and set of available commands is driven by
the provided DAS config file.  I am not sure how we might support SP OUT
parameters but we can think about that later.

I does seem like you and Luciano should team up on this.

Thanks!

  Hi,
  I am trying to create a container for DAS-SCA too (not just for
stored
  procedure) and will be able to send a working code in ML over the
  weekend.
 
  Below is summary of what I got so far from the previous mail
  discussions and
  some questions.
 
 
  The integration between DAS and SCA can happen at application level
as
  service or at container level.
 
 
 
  2 different possible approaches –
 
  static – e.g. getAllCustomers
 
  dynamic – e.g. execute(all customers);
 
 
 
  For application level service – it is the sample *
  sample-StoredProcedureService.jar*  or what Luciano is providing in
 more
  details, is an example.  In *sample-StoredProcedureService.jar*
 example
  dynamic approach is followed
 
 
 
  For container approach – again static or dynamic approach can be
  followed.
  For static – it's like providing service for getAllCompanies(),
  getAllCustomers() etc. whereas for dynamic its like execute(command)
  where
  command can be getAllCompanies, getAllCustomers. Etc.
 
 
 
 I am working on a container implementation where dynamic
  approach is followed.
 
 If I understand correctly, the container approach will provide the
 tightest integration with SCA and make things easier for end-users.  Do
 you agree?

 
 
  There are 2 places where extensibility is required –
 
  1)  for providing different data access mechanisms. i.e. today
  there is
  RDB-DAS, tomorrow there will be XQUery-DAS etc. In this case – the
  scdl will
  be same, but the exampleconfig.xml will change.
 
  In the container I am working on - Scdl has a new tag

[jira] Updated: (TUSCANY-908) CDATA sections are not handled

2006-11-08 Thread Simon Laws (JIRA)
 [ http://issues.apache.org/jira/browse/TUSCANY-908?page=all ]

Simon Laws updated TUSCANY-908:
---

Attachment: cdata.txt

A preliminary patch for handling CDATA sections. The approach taken is to allow 
CDATA sections to appear in property values within data objects. In this way 
CDATA can be accessed through the standard SDO API for either reading or 
creating strings,i.e. what you see is what you get. The user must be aware of 
the syntax of CDATA section markers and be prepared to process them. 

This gives us to oppotunity to experiment wih CDATA a little and see how we 
feel about this approach. It was not the only approach considered when looking 
for a solution. In particular the introdcution of special flags to the SDO core 
was considered. This approach is problematic when CDATA sections appear as part 
of a primitive string value. We would have to undertake so fairly serious 
changes to the SDO core to make primit string properties that contain CDATA 
sections and where in those strings the CDATA appears in order that it can be 
pulled out for processing. 

The patch has been created using subclipse which, AFAIK, doesn't support 
relative paths. Sorry about that. The answer is to decide where to apply it and 
then edit the patch file to change the contained paths appropriately.

 Simon,

 The Sequence entry returns a special property:

 if (sequence.getProperty(i) == specialCDataProperty) {
   String cDataValue = sequence.getValue(i);

 The problem is that this special property is currently inherited from
 the
 underlying EMF, so it's really not something we want clients to use.
 RIght
 now, this works fine in terms of reading in CDATA and not losing it when
 you reserialize, but there's really no proper way for an SDO client to
 actually access it. Without using EMF apis, the only way a client can
 decide that an entry is CDATA is by looking at the property name (and
 hope
 there's no real property with that name). Longer term, I'm not sure that

 even handling it this way is right. Maybe CDATA and other special XML
 things should look like mixed text in the sequence (property == null),
 and
 some XMLHelper method (or some Tuscany specific API for now) could be
 used
 to check if it's actually something special like CDATA. Maybe you should
 try to do something like that in the C++ impl, and if it looks
 promissing,
 we'll switch the Java impl to do the same.

 This is primarily a C++ question but I guess could apply to Java
 also.
   I'm
 trying to read a document into C++ SDO that contains a CDATA
 section.
   The
 corresponding CDATA doesn't make its way into the resulting SDO.
 I
 put
   the
 C++ SDO implementation in the debugger and found the reason why:


 sax2parser.cpp

 void sdo_cdataBlock(void *ctx, const xmlChar *value, int len)
 {
 }

 So the callback exists, gets called with the correct data during
 the
 parse, i.e. LibXML2 is doing the right thing, but the callback
 is
   ignored.
 Is there a good reason for this? I did a quick search of the C++
 and
   Java
 specs and they don't appear to discuss CDATA specifically. Can
 someone
 comment on whether the Java implementation handles CDATA
 successfully?

 Logically, from an SDO point of view, there is probably no need
 to
   treat
 CDATA specially as the SDO model dictates precisely the
 difference
   between
 data and structure. We may find that to make the XML DAS
 function
 work
   we
 have to know that a property potentially contains markup but I'd

 have
   to
 look closely at how the C++ SDO implementation of the XML DAS
 function
 streams out SDOs to XML when requested to do so.

 If CDATA hasn't been omitted for a good reason I'll come up with
 a
 proposal for C++ SDO.

 Regards

 Simon
   
   
   
I didn't get any response to this. Here are my further thoughts..
   
There are a number of options for representing CDATA in SDO, for
 example
   
1) Duplicate the CDATA string as is, including the ![CDATA[ and

 ]]
markers, to the appropriate property in the data object hiearchy
2) Duplicate the CDATA string excluding the ![CDATA[ and ]]
   markers
and instigate a special flag to indicate that CDATA is present.
   
CDATA is the specific concern of XML, i.e. the chracter entities
 that
   CDATA
protects an XML parser from are of no
concern to SDO because SDO is not intended to be tied directly to
 XML.
   So
given the example options above we
either expose the specifics of XML to the SDO core 2) or to the
 SDO
 user
   1).
   
Neither are particularly attractive.
   
1) appears to be the simplest approach to implement because it
 provides
   a
mechanism for the user to read, and
create CDATA without having to provide much special support in
 SDO.
 2)
   is
more involved particularly because
CDATA can appear mixed in with other text strings and so a
 sequence
 may
   need
to be used to represent properties
that have a mixture of text and CDATA marking those sequences
 entries
   that
are CDATA.
   
1) does require changes (at least in C++ SDO) because XML parsers
 tend
   to be
too helpful in this case for
processing CDATA. XML parsers, libxml2 in particular, recognize
 the
![CDATA[ and ]] sequence as a special
indicator and throw it away returning just the text it includes.
 We
   would
have to reintroduce it and store it in
the parameter value in question. The C++ SDO

  Hi,
  I am trying to create a container for DAS-SCA too (not just for
stored
  procedure) and will be able to send a working code in ML over the
  weekend.
 
  Below is summary of what I got so far from the previous mail
  discussions and
  some questions.
 
 
  The integration between DAS and SCA can happen at application level
as
  service or at container level.
 
 
 
  2 different possible approaches –
 
  static – e.g. getAllCustomers
 
  dynamic – e.g. execute(all customers);
 
 
 
  For application level service – it is the sample *
  sample-StoredProcedureService.jar*  or what Luciano is providing in
 more
  details, is an example.  In *sample-StoredProcedureService.jar*
 example
  dynamic approach is followed
 
 
 
  For container approach – again static or dynamic approach can be
  followed.
  For static – it's like providing service for getAllCompanies(),
  getAllCustomers() etc. whereas for dynamic its like 
execute(command)

  where
  command can be getAllCompanies, getAllCustomers. Etc.
 
 
 
 I am working on a container implementation where dynamic
  approach is followed.
 
 If I understand correctly, the container approach will provide the
 tightest integration with SCA and make things easier for 
end-users.  Do

 you agree?

 
 
  There are 2 places where extensibility is required –
 
  1)  for providing different data access mechanisms. i.e. today
  there is
  RDB-DAS, tomorrow there will be XQUery-DAS etc. In this case – the

[C++] Where next for Tuscany C++?

2006-11-08 Thread Andrew Borley

Hi everyone,

Now M2 is finally available, we should start thinking about what we'd
like to do next in Tuscany C++. There were quite a few items that were
suggested for M2 that we ended up leaving out for time reasons and it
would be good to progress the function we have in M2.

Things I would like to do/see:
- Add initial support for SDO handling in the Python extension (as an
XML serialization)
- Remove requirement for componentType side-files for Python components
- Get the PHP extension up to the level of the Ruby/Python extensions
- perhaps by using the SCA for PHP stuff
(http://www.osoa.org/display/PHP/SCA+with+PHP)
- Improve the samples for the scripting languages (nebulous! does
anyone have any good ideas?)
- A sample showing the different languages working together.
- A standalone REST binding - we can do a limited REST via the
support in Axis2C, but I think it would be cool to have a real
binding.rest that we can host in HTTPD.

Please join in with your own thoughts/plans!

Cheers

Andy

SCA Binder question

2006-11-08 Thread Luciano Resende

I was reading the SCA specs around what is the concept of a Binder, and my
understanding is that it's more towards the transport protocol layer. If
this is the case, how would we have a Stored Procedure as a Binder ?

SCA spec :
http://download.boulder.ibm.com/ibmdl/pub/software/dw/specs/ws-sca/SCA_AssemblyModel_V09.pdf

page 45: SCA supports the use of multiple different types of bindings.
Examples include SCA service,
Web service, stateless session EJB, data base stored procedure, EIS
service.

Could someone elaborate little more on how the SP would be used as a binder
?

Re: Adding 2 webapp jars to binary distro

2006-11-08 Thread Simon Nash

Raymond,
Thanks for these comments.  My responses are inline.

Raymond Feng wrote:


Hi, Simon.

A few comments:

1) It seems that you're looking for a collection of tuscany 
runtime/extension jars which provides you the artifacts to build the web 
application offline using ant or manually. I don't think it's 
appropriate to add them to the standalone distro though because it 
serves as the runtime for standalone applications instead of a 
traditional binary distro.



I'm not sure why you are making a strong distinction between these
two uses.  A traditional binary distro will have a bin directory
containing a command to launch its runtime and possibly other
commands as well.  Supporting dependencies that are needed to
provide core functionality are in a lib directory.  For example,
the binary distros for tomcat and ant follow this pattern.  So if
we were releasing a binary runtime distro for core Tuscany
functionality (i.e., functionality that is not part of some
extension), I think its contents would be quite similar to what we
have today in the standalone distro.

Also, what we have today seems to be something of a hybrid between
a standalone distro and a binary distro.  The extensions in the
contrib directory are not needed by the standalone launcher, but
are packaged in the same bundle (binary distro) for user convenience.
By suggesting adding the 2 webapp jars, I was trying to take this
approach of user convenience just a tiny bit further.

2) There may be another scenario that a distro is desired for web 
applications. In that case, the tuscany runtime/extension jars will be 
shared by the Tomcat server level (I remember we did a similar thing 
before by leveraging common/lib and server/lib?). This configuration is 
not supported today. I'm not sure it should be considered.



I had not intended to support this scenario.   If we decide we want
to revive support for it, then we would have some work to do on both
the runtime and build time aspects.

3) I also feel a bit scary by looking at the ant script which packages 
the WAR file. A prebuilt ant script can help one sample application, but 
won't the end-users be scared as well imaging they have to write such a 
script to deal with other web applications? Can we defer it to M3 so 
that we can have a better picture instead of rushing to M2 which is very 
close to the release?



My hope in providing some sample scripts would be to show people what
is needed in order to build and run Tuscany applications, at a more
explicit level than just run maven.  In effect this would serve as
documentation for how they could do this themselves, using whatever
tool they find most comfortable.  I agree that the current webapp
script comes across as quite scary, which is why I asked for suggestions
to improve it.

4) As for the ant script itself, I suggest that you use the nested 
elements (such as lib, classes, webinf and metinfo) for war task 
instaed of a bunch of copy tasks as documented @ 
http://ant.apache.org/manual/CoreTasks/war.html.



Thanks for this very helpful feedback.  I will work on this today and
post an updated version of the script later.  I hope this will go some
way to addressing your previous comment.


Thanks,
Raymond

I think this highlights one of the challenges with Ant-based build
environments. Although Ant provides the mechanisms for executing the
build scripts it does not provide a method for locating the
dependencies needed at build-time - for example, to compile or
repackage; often they are simply checked in alongside the user's
source. This was one of the key issues that the Maven project
originally set out to solve and which led to the establishment of the
repo systems.

I have not had a chance to see how your scripts address locating these
dependencies. I realize that some, like SDO, are (undesirably) located
in the standalone distro; others like spring, jaxb, json, js are not
(or at least I hope they are not). It would help (in my currently
disconnected state) if you could describe how your environment handles
these.

We will be making all the dependencies (including these) available
through the maven repository system. As I explained in an earlier
mail, the release vote would include not just the binary and other
archives but also /all/ of the artifacts we release through the repo;
this addresses Ant's concern about IPMC approval.

At a fundamental level, I would question whether using the standalone
runtime distribution as the basis of a build environment is the way to
be going. Would we be better served producing a library



Wouldn't if we added javadoc, SDOgen, Java2WSDL, WSDL2Java, War 
Plugin commandline to this be essentially a Tuscany SDK?



Yes, it would, and for M3 it would be good

Jeremy,
Thanks for the quick response.

I am trying to be pragmatic here and deal with simple use cases.
I haven't yet worked out the best way to deal with external or
transitive dependencies from an ant build environment (though
I do have some thoughts), but having a complete story for this
is not needed to build a simple webapp.


It seems that if you go down this route you will wind up re-inventing  
Maven. Maven seems simple enough to me.



I had not intended to reinvent maven.  I was thinking more in terms
of something that enables ant scripts to find dependencies in maven
repos and package these in the embedded repo within the war file.
I'm looking at various options for how best to do this in a way that
is most convenient from the perspective of ant users.


Adding these 2 jars
would be a simple change that would make the first use encounter
with Tuscany quite a bit easier for ant users.


Both Jeremy and Raymond pointed out the issue about working from a  
standalone distribution.


Please see my comment to Raymond on this.  I'd like to explore why
it wouldn't be appropriate to have a binary distro that could be used
for both purposes.

 There is a further issue that statically
cramming things into the distribution is not going to solve. Namely,  
moving forward, these jars are not going to be the only things  required 
to run in a web app in many of the common usage scenarios.  For example, 
there will also be pure-Tuscany things like a JNDI-based  implementation 
of ResourceHost to support the @Resource tag and  service discovery. In 
addition, people may want to use other optional  extensions such as 
Celtix instead of Axis or JAXB instead of SDO. The  best way to solve 
this other than using Maven (and potentially  embedding it as part of 
the distribution) is to use the artifact  repository at runtime or, as 
you mentioned, a custom Ant task that  replicated its functionality at 
deployment time (it could even embed  Maven :-) ). The Ant task would 
download the jars and place them in  the Ant project folder as 
determined by the user.



I am not debating the extensions issue.  We need a robust and convenient
way for ant users (and users of other build tools) to obtain optional
Tuscany extensions that aren't included in the tuscany-sca binary
distro.  I'm only focusing on the small set of binary artifacts that are
basic components of Tuscany and aren't packaged as Tuscany extensions.
I don't really see any distinction between these artifacts and the
contrib Tuscany extensions that we are including in the M2 distro.
In both cases, these could be downloaded separately, but bundling them
into a downloadable distribution is a valuable convenience to users.

What would be a less than ideal solution is to adopt the kitchen  sink 
approach. Even if today it is two jars, this will quickly break  down as 
the complexity of the runtime configuration increases.  Putting this in 
as a temporary stopgap also does not seem like a good  move given the 
issues it presents moving forward and the fact that we  would have to 
remove it in the next release.



Agreed that we don't want to do something now that we would reverse later.
I don't see why this would be necessary.  Even if we had a very
sophisticated remote loading approach, there would still be a few basic
things that it would make sense to find locally.

Perhaps a custom Ant task which replicates the functionality in Maven  
is something you could look into? If you embedded Maven, I don't  think 
it would be that much work.



I'm certainly going to look into this and I think it's the right way to
locate and load optional external dependencies.  One of the approaches
I am investigating is embedding maven.  But I would draw a distinction
between solving the general problem of artifact discovery and
downloading, and how we provide basic elements of the Tuscany runtime.

Re: DAS as a POJO service (POJService?)

The term DAS-POJO Service is probably confusing.  What I meant is 
service implemented in Java that does not require a new component type.

We need to find a way to replace the configureService API with an 
SCA pattern for providing config information.  Amita has solved this 
with the DAS-container contribution but I assume there is a pattern 
for POJO services too.


We should avoid checked exceptions.

Could the Vector argument list be replaced with a List?

I think Apache discourages the use of the @author tag

Conversational services

2006-11-08 Thread Ignacio Silva-Lepe

I'd like to re-start this thread to get started on implementing
conversational services according to the assembly and c+i for Java specs.

The following items need to be addressed:

SessionScopeContainer - A new class that needs to be created, in addition to
HttpSessionScopeContainer, since this latter class seems to be aimed
specifically at http sessions. Perhaps the two could be combined into a more
general class but I'd like to hear first whether people think this makes
sense (or was even the initial intent). If a separate class is created, we
may need to use a similar technique of passing a session id in the work
context to retrieve the corresponding correlated component instance, unless
this technique was not intended to be further used.

Session id in message - A new field would be added to a
o.a.t.spi.wire.Message to convey the session id within the local confines of
a composite. This session id would then be turned into and retrieved
from whatever represenation it takes in any given binding (more on that
below). It may be useful to provide common session id function for bindings
in o.a.t.spi.extension.ReferenceExtension and
o.a.t.spi.extension.ServiceExtension as appropriate.

Bindings and session id - Each specific binding would define its own way of
representing the session id and conveying it across the wire. Specifically,
for binding.ws, an initial approach would be to use WS-Addressing, with
other approaches (such as WS-RM) coming later. Since WS-Addressing does not
provide explicit support for session ids, we could use the convention of
adding it as a reference property or parameter in the wsa:To source endpoint
reference header.

Using the conversation lifetime summary in sec 1.5.2.5 of the c+i spec as a
template, here's an attempt at outlining the specific features of
conversations we can tackle and when:


 initially   later

start - @reference -
CompositeContext.newSession
conv  injected

continue- hold on to ref  - load persistent ref
conv  - get ref as parm   -
CompositeContext.lookupServRef

end   - @EndConversation -
ServiceReference.endSession
conv  - @EndSession on   - timeouts specified in
@Session
   calback
   - timeout (maxIdleTime
  or maxAge, hardwired)

Needless to say, I most probably have missed something so by all means, let
me know.

VS Express is able to compile our code but you may notice a fair few
warnings (which we will get round to fixing).


I like the idea of expanding the scripting language support to see where
that takes us. It will be interesting to see if there is anything common to
the different scripting languages that can be distilled into a scripting
core??

Hmm, seems like my attempt at table building below did not work well, how
about now.

Also, in 'Bindings and session id', wsa:To is obviously not the source epr.
For some reason I thought the destination address was supposed to be an epr
but as you know, it is only a URI. So I guess we could try the convention of
using a reference prop or parm in the source epr (wsa:From).

a composite. This session id would then be turned into and retrieved
from whatever represenation it takes in any given binding (more on that
below). It may be useful to provide common session id function for bindings
in o.a.t.spi.extension.ReferenceExtension and
o.a.t.spi.extension.ServiceExtension as appropriate.

Bindings and session id - Each specific binding would define its own way of
representing the session id and conveying it across the wire. Specifically,
for binding.ws, an initial approach would be to use WS-Addressing, with
other approaches (such as WS-RM) coming later. Since WS-Addressing does not
provide explicit support for session ids, we could use the convention of
adding it as a reference property or parameter in the wsa:From source
endpoint reference header, given that wsa:To is only a URI.

Using the conversation lifetime summary in sec 1.5.2.5 of the c+i spec as a
template, here's an attempt at outlining the specific features of
conversations we can tackle and when:


 initially   later

start - @reference -
CompositeContext.newSession
conv  injected

continue- hold on to ref  - load persistent ref

end   - @EndConversation -
ServiceReference.endSession
conv  - @EndSession on   - timeouts specified in
@Session
   calback
   - timeout (maxIdleTime
  or maxAge, hardwired)

I'd like to re-start this thread to get started on implementing
conversational services according to the assembly and c+i for Java specs.

The following items need to be addressed:

SessionScopeContainer - A new class that needs to be created, in addition to
HttpSessionScopeContainer, since this latter class seems to be aimed
specifically at http sessions. Perhaps the two could be combined into a more
general class but I'd like to hear first whether people think this makes
sense (or was even the initial intent). If a separate class is created, we
may need to use a similar technique of passing a session id in the work
context to retrieve the corresponding correlated component instance, unless
this technique was not intended to be further used.

Re: building c++ M2 under windows

It looks like the ant script doesn't copy the build output for the tools to
the deploy directory. For a quick fix you can copy the scagen.cmd and
scagen.jar from src_root\sca\tools\scagen\bld to src_root\deploy\bin.

Apologies for the problem.

[DAS] Towards a disconnected paging capability

2006-11-08 Thread Kevin Williams
The RDB DAS currently has a simple paging capability that is implemented 
by wrapping a Command.  Here is a simple example:


   // Build command to read all customers
   Command readCustomers = das.createCommand(select * from 
CUSTOMER order by ID);


   // Create a pager with page size 15
   Pager pager = new PagerImpl(custCommand, 15);

   // Get and work with first page
   DataObject root = pager.next();

   // Get and work with the second page
   root = pager.next();

   // First page again
   root = pager.previous();


This works well if the client of the page data is on the server but not 
so well if the client is not.   The reason is that the pager wraps a 
command instance which, in turn, references a connection.  For a pager 
to work in a disconnected mode it should probably be serializable and 
very lightweight (it might be stored in session for instance) and it 
cannot count on the original connection to be available.  I think this 
could easily be achieved by removing the instance variable from the 
pager that references it's command.  Instead, the command can  be passed 
as an argument to the paging methods like this:


 DataObject root = pager.next(someReadCommand);

Does this sound reasonable?

Raymond Feng commented on TUSCANY-913:
--

@Reference annotation is not required by the SCA CI spec (v0.95) section 
1.2.1.3:

1.2.1.3. Semantics of an unannotated POJO
A class that has no annotations and corresponding ComponentType side file can 
still be used as an SCA
component implementation. If the implemented interfaces are not decorated with 
an @Remotable
annotation, the class is considered to implement a single local service whose 
type is defined by the class
(recall that local services may be typed using either Java interfaces or 
classes) or, if the class implements a
single interface, the interface itself.
In the absence of @Property and @Reference annotations, the properties and 
references of a class are
defined according to the following rules:
1. Public setter methods that are not included in any interface specified by an 
@Service annotation.
2. Protected setter methods
3. Public or protected fields unless there is a public or protected setter 
method for the same name
The following rules are used to determine whether an unannotated field or 
setter method is a property or
reference:
1. If its type is simple, then it is a property.
2. If its type is complex, then if the type is an interface marked by 
@Remotable, then it is a reference;
otherwise, it is a property.
3. Otherwise, if the type associated with the member is an array or a 
java.util.Collection, the basetype will
be the element type of the array or the parameterized type of the Collection; 
otherwise the basetype will be the member type. If the basetype is an interface 
with an @Remotable or @Service annotation
then the member will be defined as a reference. Otherwise, it will be defined 
as a property.

Hello,
Since Axis 1.1 is soon to be out, M2 SCA Java cut will not be far behind. There

Re: Refactoring commonality amongst Script containers in Java SCA

2006-11-08 Thread ant elder

This hasn't entirely turned out as I was expecting. This container now looks
remarkably similar to the other existing ones, I thought we were trying to
refactor out the common parts to come up with an easier container SPI? Lets
take MissingSideFileException as an example, that could be reused by many
container extensions so could be in a container SPI couldn't it?

  ...ant

On 11/4/06, Jim Marino  [EMAIL PROTECTED] wrote:


O.K., I committed the refactor to container.script with the follow
changes:

1. Fixed the project so it builds again :-) (it is not part of the
default build)

2. Removed the need for Async target invokers based on core changes

3. Remove ComponentType hack as that has been fixed in core

4. Changes to better leverage SPI
- Removal of all the helper classes. I was able to factor these
out by using stuff from SPI, class hierarchy simplifications, e.g.
ScriptImplementation
- Scripts now instantiated in the build phase as opposed to
loading
- Stronger typing of errors, e.g. MissingSideFileException
- Use of ObjectFactory for creating Script instances

5. Fix issue where mutable properties were not thread-safe (i.e.
instances were shared across implementation instances).

6. Remove dependency on core impl classes and cleanup some of the
unit tests

7. Fix checkstyle warnings and PMD failures

8. Add license file

9 Use a config class for creating a ScriptComponent as that takes a
number of constructor parameters


There are also some things that could be done as potential improvements:

1. Better test quality.
- There are no real tests involving invocations and wires to and
from scripts. This could be set up with EasyMock in a pretty
straightforward way without the need for SCATestCase
- Likewise for properties, we should test accessing properties
from within a script.

2. Support for scopes other than module.

3. Some of the class hierarchies seem like they could be simplified,
flattened, or removed. For example, ScriptInstance and its
implementation could potentially be removed completely and just have
the ScriptComponent return the BSF engine (ScriptTargetInvoker would
need to be changed for this to carry additional information).

   You said you'd take on getting the things like the async
 code into
   the spi
   to avoid all that duplicate code so would you like to go
 ahead and
   do that
   now? (or I can do it if you like).
   O.K. I committed the changes. There is no need to handle
 message id
   correlation as the wiring fabric (specifically
   TargetInvokerExtension) does it automatically. You should be
 able
   to delete AsyncMonitor and the async target invoker. You will
 also
   need to change some of the signatures of the builders to pass
 in a
   WorkContext and ExectionMonitor (these are autowired to
   ComponentBuilderExtension). I made some basic changes the the
   script container to pass tests but you will probably need to do
   some more (limited) refactoring to get it fully operational. I
   fixed the Groovy container so you can use that as an example.
 (BTW,
   as a side note, container.script is not part of the build by

   The other changes to make are to create a script
 specialization of
   ComponentType in the loader and use ObjectFactory for creating
   instances.
  
   Once the componentType and async changes
   are done I/we can look at the next things to simplify and
 once all
   that
   refactoring is done I'll look at what remains in the helper
   package and see
   if there are still things I think could be simplified.
  
   If you can make those changes, we can take another pass over the
   helper classes and see what is left.

Re: ServletLauncherInitException: Autowire target not found

2006-11-08 Thread Ignacio Silva-Lepe

To answer my own question, with help from Jim, it turns out that the
webapp.scdl in the sample was not in sync with that in runtime/webapp-host;
in fact they're both different from each other. The one in the sample was
missing the resource host registry entry, and the one in runtime was missing
the databinding includes.
This begs the question of why the sample has its own copy of webapp.scdl. In
fact a lot of (if not all) the web samples have their own copy. Would it be
better/possible to have them copy it from runtime at build time?

Re: [DAS] Towards a disconnected paging capability

2006-11-08 Thread Luciano Resende

Would this proposal implicate in performance degradation over a local
environment, compared with what we have today ? As the pager would have to
connect and execute the command every time the pager moves to the next or
previous pages ?

If we could come up with same interface for connected and disconnected
pagers, maybe we could have a pager factory that you would instantiate
either one, connected pager (current version) or disconnected pager (what
you are proposing). This could give us a better flexibility and we would
leave the decision to the api consumer, where he would balance his
performance needs...

Technically it's fine, but conceptually I'm not sure about passing a
command object to a pager. What does it mean to page a command?

Another option would be to get rid of the Pager altogether. The only
state held in the Pager if you get rid of the Command is the page size
and current index. We could easily stash those on the root DataObject
(even in the static case we will have a containing DataObject created
by the DAS.) Then you could move nextPage(), previousPage(), and
getPage() to Command.

There would be no performance implication since each pager next or

Re: Refactoring commonality amongst Script containers in Java SCA

2006-11-08 Thread Jim Marino


On Nov 8, 2006, at 2:08 PM, ant elder wrote:

This hasn't entirely turned out as I was expecting. This container  
now looks

remarkably similar to the other existing ones,

I see this as a good sign...to me it means we are arriving at an SPI

I thought we were trying to
refactor out the common parts to come up with an easier container SPI?
Yes and I couldn't find much to factor into the kernel. However, I  
did factor things out that were redundant with the later.

Lets
take MissingSideFileException as an example, that could be reused  
by many

container extensions so could be in a container SPI couldn't it?

MissingSideFileException could be moved up. However, I would be very  
cautious about moving implementation classes. There is always a trade- 
off in SPI design between providing out-of-the-box implementations  
versus too tightly coupling extensions to the containers they are  
extending. If there are too many implementation classes in an SPI, it  
will render the latter inflexible and it will be difficult to evolve  
in a backward compatible way in the future. For example, we can take  
a few specifics:


1. ScriptComponentBuilder. Injecting of properties is specific to the  
implementation type. One thing that we could potentially change is  
having scope containers passed in. We should think about this.


2. ScriptComponentTypeLoader. How a component type side file is  
resolved for an implementation type is specific to it. Providing  
utility classes for trivial operations such as reading streams will  
just complicate the SPI needlessly.


3. ScriptImplementationLoader. Pretty much the same comments as for  
ScriptComponentTypeLoader.


One thing that could be simplified in the extension (as I mentioned  
previously) is ScriptInstance could be removed altogether. What do  
you think?


Perhaps I'm just not seeing what could be moved up. Could you  
elaborate on the specifics?

O.K., I committed the refactor to container.script with the follow
changes:

1. Fixed the project so it builds again :-) (it is not part of the
default build)

2. Removed the need for Async target invokers based on core changes

3. Remove ComponentType hack as that has been fixed in core

4. Changes to better leverage SPI
- Removal of all the helper classes. I was able to  
factor these

out by using stuff from SPI, class hierarchy simplifications, e.g.
ScriptImplementation
- Scripts now instantiated in the build phase as opposed to
loading
- Stronger typing of errors, e.g. MissingSideFileException
- Use of ObjectFactory for creating Script instances

5. Fix issue where mutable properties were not thread-safe (i.e.
instances were shared across implementation instances).

6. Remove dependency on core impl classes and cleanup some of the
unit tests

7. Fix checkstyle warnings and PMD failures

8. Add license file

9 Use a config class for creating a ScriptComponent as that takes a
number of constructor parameters


There are also some things that could be done as potential  
improvements:


1. Better test quality.
- There are no real tests involving invocations and wires  
to and

from scripts. This could be set up with EasyMock in a pretty
straightforward way without the need for SCATestCase
- Likewise for properties, we should test accessing  
properties

from within a script.

2. Support for scopes other than module.

3. Some of the class hierarchies seem like they could be simplified,
flattened, or removed. For example, ScriptInstance and its
implementation could potentially be removed completely and just have
the ScriptComponent return the BSF engine (ScriptTargetInvoker would
need to be changed for this to carry additional information).

[16:00] Amita sorry lost connection for 1 min
[16:00] kevin_ sorry i missed your invite last night
[16:00] Amita np
[16:01] kevin_ did you and luciano get a chance to discuss the SCA
integration?
1[16:01] lresende we chated little bit, more towards getting the meeting
today
[16:01] kevin_ i see
1[16:02] lresende i was just looking into the documentation and some code
provided by Amita
[16:02] kevin_ i committed Luciano's sample this morning ... mayb e we can
start with that
1[16:02] lresende sure
[16:02] ant_ quick question from me before you get into that,
1[16:02] lresende i conside the sample a first step on getting
integration between DAS and SCA
[16:02] kevin_ you may have to help me with some terminology
[16:02] kevin_ sure
[16:02] kevin_ right
[16:02] ant_ Amita, are you still looking at the stored procedure stuff?
[16:02] kevin_ that makes sense
1[16:03] lresende in that, i expose DAS as simple SCA service and uses a
web app to consume it
[16:03] Amita looking at all CRUD+SP support and not only SP
1[16:03] lresende the service supports any kind of command supported by
das today
[16:03] Amita have a container supporting that for static and dynamic
approaches
[16:03] ant_ so not a binding or container specifically for stored
procedures?
[16:03] kevin_ ant , i think we can treat SP and CRUD the same
[16:03] Amita yes
[16:04] ant_ was that a yes to me or kevin_?
[16:04] Amita yes - support all DAS commands not only SP
[16:04] ant_ hmm
[16:05] kevin_ ant ... do you think we need something specific to SP
[16:05] Amita ant - you have some point to deal with only SP - some
reason?
[16:05] ant_ well thats what TUSCANY-876 was for. The use of DAS was just
an implementtaion detail
[16:06] kevin_ my motivation id SCA/DAS
[16:06] ant_ i understand
[16:06] ant_ that
[16:06] kevin_ do we need a seperate effort?
1[16:08] lresende ant: i have closed that, as Amita created a new one,
more generic... but looks like i should re-open that?
[16:08] ant_ well both venkat and i have suggested that yes
[16:08] kevin_ sounds like it is more and less generic :-)
[16:09] ant_ you guys continue with what talking about on this chat, i
don't want to hold that up
[16:09] kevin_ np, thanks
1[16:09] lresende thanks ant...
[16:09] kevin_ luciano.  i did not see a working test with the sample
[16:10] kevin_ is that in the works or, did i just miss it
[16:10] Amita ant, still not clear about separate effort for SP?
[16:10] kevin_ ok
1[16:10] lresende kevin: you mean, junit testing for das.service ?
[16:10] kevin_ any test ... junit woiuld be good ... htmlUnit
1[16:11] lresende i'm planning to have same way we do for companyweb,
with htmlUnit and TC
[16:11] kevin_ i did not see a way to test the sample
[16:11] kevin_ cool
1[16:11] lresende comming
1[16:11] lresende soon
[16:11] ant_ Amita, you're a volunteer so I want you to work on what
interests you. TUSCANY-876 can wait for who ever is interested
[16:12] Amita kevin: Kevin - one question - could not get you point on
Update SQL - in code am using dObj.set(idx, val);
[16:12] kevin_ amita/ant .  DAS/SCA integration is one thing ... I guess
that a generic SP integration couls be another
1[16:12] lresende TUSCANY-876 is reopened
[16:12] Amita OK
[16:13] ant_ thx
[16:13] kevin_ Amita.  Are you referring to my question about using Change
History to drive updates?
1[16:14] lresende ok, Amita, do you have specific topics, questions
around the das container ? or around das ?
[16:15] Amita yes - one question - about DAS
[16:15] Amita would like to know use of ConnectionInfo tag for a non web
scenario
[16:15] Amita is there some code - I can take a look at - where for non
web , it is used?
1[16:15] lresende ok, first...
1[16:16] lresende i think we should probably add a SCDL tag for
connection info
[16:16] kevin_ the connection tag is only used today to specify a
DataSource
[16:16] kevin_ so, that us is specific to DataSource not web
[16:17] kevin_ the other option is to explicitly provide the DAS with a
JDBC Connection instance3
1[16:17] lresende as we might deploy the same service into a C++
environment, and that connection info would be invalid
[16:17] Amita yes
[16:18] Amita so in Java, how to make the context available ? in web - we
can have it in server conf of tomcat etc
[16:18] kevin_ so, all RDB DAS test cases use the Connection instance
approach since ...
[16:18] Amita but when standalone and want to use Connection info, how to
do?
1[16:18] lresende you would use

Hi Guys

  Amita have started work to expose DAS as an SCA container, and we are
looking what would be the best way to get collaboration on continuing the
task. One of the ways we were thinking was to clean-up what is available
today and get it into the trunk, so we could share and continue contributing
by submitting patches. Is that the way to go ? Any other ideas ? If that's

Re: Exposing DAS as an SCA container - Where contribution should go for better collaboration ?

2006-11-08 Thread Jim Marino

Hi Luciano,

Is the DAS container a component or binding? If it is in the former,  
I would think it should go under container/container.das, otherwise  
binding/binding/das/


Also, the dependency in the module should be against a version of DAS  
and not the DAS project directly so that it is treated as an external  
dependency like Axis or OpenEJB.

 We need to find a way to replace the configureService API with an

Yes, this was THE thing I know we need to improve as mentioned on this

SCA guys, any suggestions about something already available in SCA ? Or
maybe an Annotation ?


Amita has solved this with the DAS-container contribution but I assume

there is a pattern
 for POJO services too.

 We should avoid checked exceptions.




Could you elaborate little bit more here ? Why  exactly this ?


Could the Vector argument list be replaced with a List?

 I think Apache discourages the use of the @author tag



Sure, it was just a setting in my eclipse IDE, I'll create a patch removing
that.
As for the other things... I'll look into that and provide a patch with the

Thanks for the website work. It looks better and is easier to navigate

Minor comments
- We already mention that Tuscany is under Apache License 2.0 in the
overview. It does not seem necessary to have an entry called license and ASF
under General section.
- Down load page should contain an entry that describes content of each
release. For example, what is in SCA Java M1.
- Can FAQ be a link to Wiki? It would be easier to update by anyone.

- How to Add info about SCA extensions?
1. Add Extension entry to SCA navigation tab on the left after SCA C++.
2. Create a top level  navigation for 'SCA lang extensions' just like what
we have for SCA, SDO, DAS. It could contain  overview, documentation,
download (maybe) entries. The challenge will then be how to separate
extensions provided on top of C++ or Java runtimes.

Option 2 seems easier to navigate through.

Re: OSGi Binding

2006-11-08 Thread Jim Marino

Hi Nicole, Joel, and others,

Sorry it took me so long to respond (I was out a few days, traveling,  
and then backlogged)...Here are some thoughts on the slides Nicole  
put together (Thanks!) as well as to the email thread.


I was thinking the OSGi container would be a host environment that  
Tuscany would be integrated with, similar to Tomcat, Jetty, or a J2EE  
server. As such, it would have some special capabilities:


1. As Nicole mentioned, there would be a special OSGi binding for  
composite references and services. For references, the OSGi binding  
would provide a connection to an OSGi service. For services, the  
OSGi binding would essentially publish an SCA component (to be  
technically correct, a service offered by an SCA component to the  
OSGi service registry. This would allow OSGi services to consume SCA  
services. This is somewhat analogous to ServletHost (e.g. OSGiHost)  
where Tuscany deployed on a servlet container can register Servlets  
in that container (related to this, we probably want to have the  
ability for the OSGi container to provide an implementation of  
ServletHost that registers Servlets using the OSGi http service  
mechanism). We will have to address the more dynamic nature of OSGi  
services. I would also like to avoid proxying the OSGi services if  
possible.


2. The OSGi container would isolate SCA application composites  
according to its classloader semantics.



Currently, Tuscany has two composite trees, an application and system  
tree:



Runtime
|
   /\
 /\
   / Root System Composite
  / 
Root Application Composite

The root composites may contain child composites. The system  
composite tree contains runtime extensions such as Axis. Each  
composite has its own classloader. This maintains isolation between  
application composites and runtime extensions.We plan on introducing  
a multi-parent classloader for system composites. This is arises from  
the need to support scenarios where application code may need to  
access dependencies associated with a system extension. For example,  
application code may need to access classes in Spring. These classes  
need to be shared with the application composite classloader. We were  
planning on loading dependencies that needed to be shared in a parent  
classloader of the system extension classloader. The former  
classloader would then also become a parent of the application  
classloader (which would have multiple parents).


One issue is going to be reconciling this scheme with OSGi's  
classloading infrastructure. In relation to this, I was thinking we  
would want a common packaging mechanism for Tuscany extensions across  
host environments. For example, the Axis2 extension should not have  
to be repackaged or modified when deployed on Tomcat or Equinox.  
Application composites, however, could be bundles. I was thinking  
there would be one Tuscany runtime deployed to an OSGi container.  
This would get bootstrapped (as Joel mentioned) by a BundleActivator  
and would look similar to the web app launcher with one exception.  
Namely, while the web app launcher boots the runtime in a separate  
classloader, the BundleActivator would not need to do this and would  
instead boot Tuscany in the bundle classloader. The Tuscany runtime  
bundle would consequently  have to export classes used by  
applications such as SCA API.


Applications would be deployed as bundles as well. It would be nice  
if we could listen to bundles coming online and check for SCA scdl  
(configuration files). If one is found, we load the bundle as an  
application composite and stick it in the runtime application tree.  
The classloader for this composite would be the bundle's. The bundle  
itself would have to import certain SCA packages (i.e. the ones  
exported by the runtime bundle).


The hard part is going to be figuring out how to deal with  
extensions. Specifically, in the case I mentioned above where  
application code needs to reference certain extension classes. I  
would like to avoid having special packaging for Tuscany extensions  
when deployed to an OSGi container versus the Servlet container. So,  
we could deploy the same Axis2 extension to Tuscany on an OSGi  
container and Tuscany on a Servlet container. This would mean the  
runtime would have to behave slightly differently depending on this  
host. In this respect, perhaps what we could do is instead of  
creating a parent classloader to the extension and also having it as  
a parent to the application, we could have OSGi manage this? One way  
to do this would be for a particular extension to use just the bundle  
classloader and programmatically export packages that need to be  
shared (is there an OSGi api to do this, I recall a dynamic export/ 
import)? One the application side, the bundle import those packages.


Do you guys think this makes sense? I have some skeletal code

Re: DAS as a POJO service (POJService?)

2006-11-08 Thread Jim Marino
Isn't this a component whose implementation is a DAS query (not DAS  
itself)? The component offers a service which is defined as  
DASService. So, instead of Java code, we are using a query.


I say this because in SCA we don't really have the notion of an  
implementation-less service and a component is defined by the SCDL  
component entry so there is always a component.

Amita has solved this with the DAS-container contribution but I assume

there is a pattern

 We should avoid checked exceptions.

The problem here is that our runtime will try to resolve the dependencies

our test maven repo is not on that list. Once our M2 is officially out,

 Hi,

 From whatever little I understand I would imagine that the config.

 something that you will inject in as component properties. i.e. have a
 property in the DAS ComponentType to inject the source of this
 config info
 (could be a the config filename or a URL that you can open and read
 the
 config...).
Instead of injecting a URL couldn't it just inject whatever config
was required? This would save having an extra artifact separate from
the SCDL which would make tooling a bit easier.



Yes ideally, but I guess this config info is going to be quite big - so a
whole lot of properties might be required.  Maybe it would still be ok and
its just that I am not yet used to seeing component defintions with lots of
properties. :)



 If this SCA Service abstraction of DAS is complete, maybe we must
 actually
 think of  projecting it distinctly outside the SCA  DAS
 infratructures - as
 a component that is ready to use - i.e. can be pulled down and used
 in a
 service assembly.  Makes sense?

I'm not following. I thought this would be a component implementation
type, like implementation.java. The configuration would be specified
in the component SCDL entry:

component
implementation.das
!-- optional in-line query --
/implementation.das
property name=foobar/property
/component

The extension could be dynamically provisioned by the runtime but the
application SCDL would contain the above.

I did something similar for DataSources over the weekend in the
persistence module.



I guess this is something Amita and Luciano are going to put in place soon.
Right now, what has been done is an SCA Application Service abstraction of
DAS.  Maybe Luciano should correct me if I have understood this all wrong.

Re: DAS as a POJO service (POJService?)

2006-11-08 Thread Luciano Resende

Yes, Jim comments are more towards what's coming...

What we have today (das/samples/das.service and
das/samples/das.service.client) is more towards integration on the
Application Layer as Venkata mentioned... And that's how I don't know how to
get rid of the configureServices...

  Hi,
 
  From whatever little I understand I would imagine that the config.
  info is
  something that you will inject in as component properties. i.e. have a
  property in the DAS ComponentType to inject the source of this
  config info
  (could be a the config filename or a URL that you can open and read
  the
  config...).
 Instead of injecting a URL couldn't it just inject whatever config
 was required? This would save having an extra artifact separate from
 the SCDL which would make tooling a bit easier.


Yes ideally, but I guess this config info is going to be quite big - so a
whole lot of properties might be required.  Maybe it would still be ok and
its just that I am not yet used to seeing component defintions with lots
of
properties. :)




This shouldn't be that big, as we only need a pointer to the das config
file.



  If this SCA Service abstraction of DAS is complete, maybe we must
  actually
  think of  projecting it distinctly outside the SCA  DAS
  infratructures - as
  a component that is ready to use - i.e. can be pulled down and used
  in a
  service assembly.  Makes sense?
 
 I'm not following. I thought this would be a component implementation
 type, like implementation.java. The configuration would be specified
 in the component SCDL entry:

 component
 implementation.das
 !-- optional in-line query --
 /implementation.das
 property name=foobar/property
 /component

 The extension could be dynamically provisioned by the runtime but the
 application SCDL would contain the above.

 I did something similar for DataSources over the weekend in the
 persistence module.


I guess this is something Amita and Luciano are going to put in place
soon.
Right now, what has been done is an SCA Application Service abstraction of
DAS.  Maybe Luciano should correct me if I have understood this all wrong.



Right...this is comming, we had a IRC Chat today to see how we can get it
asap :)

Re: Tuscany Website Updates

2006-11-08 Thread David Sanders

I prefer:
-  the new website's tab-less look.  If the menu on the left gets too
cluttered, the SCA, SDO, etc. sections could be made collapsible/expandable.
- the  current (live) site's color combo

Also, on both sites, the instructions for building Tuscany, running samples,
and Eclipse usage appear in multiple places, with some differences:
http://people.apache.org/~rfeng/tuscany/site-publish/java-projects.html

 Thanks for the website work. It looks better and is easier to navigate

 Minor comments
 - We already mention that Tuscany is under Apache License 2.0 in the
 overview. It does not seem necessary to have an entry called license and
ASF
 under General section.
 - Down load page should contain an entry that describes content of each
 release. For example, what is in SCA Java M1.
 - Can FAQ be a link to Wiki? It would be easier to update by anyone.

 - How to Add info about SCA extensions?
 1. Add Extension entry to SCA navigation tab on the left after SCA C++.
 2. Create a top level  navigation for 'SCA lang extensions' just like
what
 we have for SCA, SDO, DAS. It could contain  overview, documentation,
 download (maybe) entries. The challenge will then be how to separate
 extensions provided on top of C++ or Java runtimes.

 Option 2 seems easier to navigate through.

It seems that if you go down this route you will wind up re- 
inventing  Maven. Maven seems simple enough to me.

I had not intended to reinvent maven.

Not yet, but you will (see below) ;-)

I was thinking more in terms
of something that enables ant scripts to find dependencies in maven
repos and package these in the embedded repo within the war file.
I'm looking at various options for how best to do this in a way that
is most convenient from the perspective of ant users.

In order for this to work, you are going to need to handle transitive  
dependencies in all but the simplest use case. Namely an application  
that cannot receive or make remote invocations. I don't see any way  
around this. For example, all of the web services binding extensions  
and container extensions have dependencies.  Bundling the two jar  
files mentioned previously will only allow someone to create a web  
application that invokes a local service from a servlet or JSP. No  
services exposed over remote bindings. No references with remote  
bindings. That type of application doesn't strike me as very  
compelling for Tuscany. In fact, I would tell people not to use  
Tuscany for this and to use something more appropriate such as  
PicoContainer. If someone was doing this to understand how to write  
Java services, I would tell them to use the standalone client since  
deploying to a web container for this sort of thing is superfluous.  
What benefit would they gain except the rigamarole of having to  
create a war (or an exploded directory) and wait for a server whose  
capabilities they are not using to restart for every change they  
make? Running the kernel inside an IDE takes milliseconds and does  
not require a deployment.


What I would recommend doing to help Ant users is to create a utility  
that can be invoked from an Ant Task, programmatically, or from the  
command line which downloads transitive dependencies from a Maven  
repository. As an implementation strategy, the first place I would  
look at is just wrapping Maven (or Wagon, the part that actually does  
the downloading).  I would also keep in mind that reusing Maven will  
avoid the trouble of having to write code that parses and understands  
Maven POMs. I would also look to see what can be shared with the  
Maven War plugin we currently have to avoid duplicated effort and code.



 There is a further issue that statically
cramming things into the distribution is not going to solve.  
Namely,  moving forward, these jars are not going to be the only  
things  required to run in a web app in many of the common usage  
scenarios.  For example, there will also be pure-Tuscany things  
like a JNDI-based  implementation of ResourceHost to support the  
@Resource tag and  service discovery. In addition, people may want  
to use other optional  extensions such as Celtix instead of Axis  
or JAXB instead of SDO. The  best way to solve this other than  
using Maven (and potentially  embedding it as part of the  
distribution) is to use the artifact  repository at runtime or, as  
you mentioned, a custom Ant task that  replicated its  
functionality at deployment time (it could even embed   
Maven :-) ). The Ant task would download the jars and place them  
in  the Ant project folder as determined by the user.
I am not debating the extensions issue.  We need a robust and  
convenient

way for ant users (and users of other build tools) to obtain optional
Tuscany extensions that aren't included in the tuscany-sca binary
distro.  I'm only focusing on the small set of binary artifacts  
that are

basic components of Tuscany and aren't packaged as Tuscany extensions.
I don't really see any distinction between these artifacts and the
contrib Tuscany extensions that we are including in the M2 distro.
In both cases, these could be downloaded separately, but bundling them
into a downloadable distribution is a valuable convenience to users.

What capabilities would this distribution have (please see my  
comments above)? I think not much.


What would be a less than ideal solution is to adopt the kitchen   
sink approach. Even if today it is two jars, this will quickly  
break  down as the complexity of the runtime configuration  
increases.  Putting this in as a temporary stopgap also does not  
seem like a good  move given the issues it presents moving forward  
and the fact that we  would have to remove it in the next release.
Agreed that we don't want to do something now that we would reverse  
later.

I don't see why this would be necessary.  Even if we had a very
sophisticated remote loading approach, there would still be a few  
basic

things that it would make sense to find locally.

I just don't get this. If I have to remotely download extensions  
anyway, why would we complicate things by cramming web app-related  
libraries into a standalone distribution?

because it serves as the runtime for standalone applications  
instead of a traditional binary distro.

I'm not sure why you are making a strong distinction between these
two uses.  A traditional binary distro will have a bin directory
containing a command to launch its runtime and possibly other
commands as well.  Supporting dependencies that are needed to
provide core functionality are in a lib directory.  For example,
the binary distros for tomcat and ant follow this pattern.  So if
we were releasing a binary runtime distro for core Tuscany
functionality (i.e., functionality that is not part of some
extension), I think its contents would be quite similar to what we
have today in the standalone distro.

There is nothing core about the web app launcher. Many deployments  
of Tuscany will not be to Servlet containers.

Re: DAS as a POJO service (POJService?)

You could find it here :
https://svn.apache.org/repos/asf/incubator/tuscany/java/das/samples/das.service/src/main/java/org/apache/tuscany/samples/das/service/DASServiceImpl.java

DAS could use a external file as a configuration file, where commands can be
defined externally (e.g. SQL Queries). This is optional, and calling
configureService would tell the SCA service to use a specific config file.
The config file is used on the DAS factory.

this.das = DAS.FACTORY.createDAS(config);

A config file would look like :
