For MDB:s this is not possible, and will not be possible of the final
EJB2.0 spec is not changed.

You will have to manage that outside the J2EE environmen, in an MBean
for example.

Re: [JBoss-user] MBean access via JNDI - How to?

[David Jencks]

Hi,
Out of curiousity, what kind of thing does your mbean do? How is it
appropriate for an ejb to be controlling it?

Waiting for the expansion of my horizons,

Re: [JBoss-user] EJB Question

[David Jencks]

Hi,

>From a practical standpoint, usually entity beans have 'individual field'
data access methods, and usually when you have a business process step,
more than one field is affected.  To get all the modifications in one
transaction without jumping through external transaction control hoops and
obviating the main reason you got an app server in the first place, put a
method that does all the changes at once in a session bean.  Automatically
( unless you mess with the transaction attributes of the methods)
everything is in one transaction.

>From an architectural standpoint, the entity beans pretty much represent a
data access layer, session beans expose a business process interface, the
flow control outside the ejb container a presentation manager, and what
actually makes the ui such as jsps a presentation layer.  Mixing up any of
these layers, such as exposing the data access interface to the
presentation manager layer, means _much_ more difficulty when it comes time
to extend or replace a layer.

Hope this helps

Re: [JBoss-user] Are readonly beans/transactions possible?

[David Jencks]

Hi,

I have several comments

1.  Firebird and Interbase have default snapshot transaction isolation. 
This is almost serializable.  All reads are indeed within a transaction (as
correct transactional semantics require -- if you think about it for a
minute, read committed is just plain broken as far as logical consistency).
 You leave out a lot of details such as how much work is in one
transaction, it is hard to know just what is going on.  You might try using
the interbase connection methods get/setLockResolution to make sure lock
contention is waiting rather than immediately returning an exception, and
for this presumably "info" request you might try setting the transaction
isolation level lower, again with connection properties.  If you are using
the non JCA minerva pools, I believe you can set these in the properties of
the XADataSourceImpl, in the same section as the user name and password. 
(I'm not 100% sure, its been a while).  I think you can set them in the

 section if you are using the JCA with for example BlackBox adapter.


2. Even if you fix this, you probably have 2 design problems if you are
calling findAll on a bean with any number of instances.  If you are sending
the data out of the container, you don't want to hold anything in a
transaction while a slow human looks at it, so there's no particular reason
to go to all the trouble of loading beans for all those rows that aren't
going to change.  Most authors I have read ( such as Richard Monson-Hefael)
suggest using a query from a stateless session bean, and just making a
collection or some text or xml to get the viewable data out. Then when the
user decides what to do, you load just the beans they actually need.  I
don't find this terribly elegant, but you really don't want to keep
involving entire tables in transactions when nothing is changing in most of
it.  There is also a user interface question, if there are more than say 10
rows in this table, why are you overwhelming the user with data?


So I've made a lot of assumptions here about what you are trying to do, and
made a couple of suggestions.  If you are trying to do something else,
please say so.

Thanks

Re: [JBoss-user] Getting a database connection using the jBoss connection pool

[David Jencks]

Hi,

Driver manager will only get you unpooled connections.

The best solution would probably be JCA resource adapters, but I doubt many
other app servers support them yet.

I think you ought to be able to bind a connection pool such as Minerva into
any jndi system in any app server, and access it as a datasource as does
jboss. The inside the ejb code ought to be app server independent.  How you
would bind it is an app server specific question, and is going to be app
server dependent.

Thanks

If my guess is correct, this is another example of "WebLogic poisoning".

Before WLS had DataSources, the way to use the connection pools was to use
a special JDBC driver.  I seem to recall seeing something similar in Minerva.

Re: [JBoss-user] Get Database connection from Jndi

[Guy Rouillier]

The minerva source is in the jbosscx component, which can be downloaded from
the JBoss site.  Look in jboss.jcml for some examples of how to use it.  You
should be able to just instantiate XAPoolDataSource and then start with a
getConnection().  (I haven't done this, so you'll have to work with it a
little bit.  You can also search the tomcat archives for some suggestions on
database connection pools other than jboss.

Yeah, because queues and topics are so non-dynamic, it seems to me
that using a messageSelector is really the only way to get much
practical use out of JMS.  It's very non-OO, but it's working for me.
 Check out
http://java.sun.com/j2ee/j2sdkee/techdocs/api/javax/jms/Message.html
for details on the syntax of the messageSelector.  Let me know if I
can help you out.

DriverManager won't give you a connection from a pool. It will create a 
new connection every time you call getConnection.

No it isn't. The _standard_ way to do this in an EJB is to do a JNDI 
lookup for a name that looks like "java:comp/env/jdbc/MyPoolName". This 
is portable across application servers because the spec says that it has 
to work.

[JBoss-user] Filtering JMS Messages

[Michael Hustler]

I have read in a different thread of 3 ways to create temporary Topics.  2
of these are non-portable and the 3rd one is limited such that the message
consumer must be created by the topic creator or something like that.

I am looking for a way to reduce the total potential message flow in the
system by filtering the message delivery.  My Message Consumers will
typically be able to specify information used to reduce the number of
messages that are delivered to them:
- publisher identity
- finer granularity of message type (determined at runtime)
- attribute values

I want to be able to determine this filtering at runtime instead of in the
deployment descriptor.

I have been trying to read-up on "MessageSelector", but I can't find any
documentation on how to apply this in an J2EE environment.

Can anyone guide me in the right direction?
Thanks,

[JBoss-user] Joins - CMP Entity Beans - BUG????

[Vinay Menon]

Hi,
   Following the example provided in the online documentation I've tried 
getting the join working across 2 tables.

The table structures are

Table A
Col1,Col2,Col3

Table B
Col1,Col2,Col4

Col1 and Col2 form the primary key for both the tables.

The finder definition is

  
findForXXByYYZZ
,B
   WHERE B.Col1 = A.Col1
   AND B.Col2= A.Col2
   AND A.Col2= {0}
   AND A.Col1 = {1}


The sql that I'd wanted the finder to produce was

SELECT A.Col1, A.Col2
FROM  A,B
WHERE B.Col1 =  A.Col1
AND B.Col2=  A.Col2
AND A.Col2= {0}
AND A.Col1 = {1}

   The sql produced, however, seems to be

SELECT A.Col1, Col2
FROM  A,B
WHERE B.Col1 =  A.Col1
AND B.Col2 =  A.Col2
AND A.Col2= {0}
AND A.Col1 = {1}

Now Col2 is an ambiguous column and the query, obviously would fail.

Has anyone come across this and found a work around? Is anyone on the JBoss 
Developers list working towards fixing this?

Please do let me know

Kind Regards

Especially the transaction support.

Nearly as a normal method call. The spec dictates that the method calls 
always behave as though they're remote insofar as passing of references 
go. This can be turned off for performance reasons.

Comparing this to a non-ejb helper that's used (for example) as a bean 
on a JSP page, you should save a lot of memory and garbage collection 
overhead.

As the docs state, JBOSS_HOME has to be replaced with the path to your

Your classpath looks strange.  I think you mean %JBOSS_HOME% instead of just
JBOSS_HOME.

Re: [JBoss-user] Getting a database connection using the jBoss connection pool

[Guy Rouillier]

If you are using DriverManager, then you are just getting a straightforward
JDBC connection, and JBoss has nothing to do with it.  So use your standard
url string; here is a sample for Oracle:

"jdbc:oracle:thin:@xyz.mycompany.com:1521:mydb"

Thank Guy.

  I have download open source DBDatabaseBroker which have connection
pooling yesterday.

  BTW , you have stated that JBoss have connection pooling called
minerva. 
  How to setup MINERVA and call it ??

[JBoss-user] JDBC Sybase configuration?

[Jason Wells]

Hello,

I'm trying to get JBoss to use the Sybase JConnect 5.2 JDBC driver for CMP
entity beans. I've been looking at the "Using MS SQL Server with JBoss"
tutorial on the JBoss site, which is the closest thing I've found in terms
of relevant documentation:

http://www.jboss.org/documentation/HTML/ch11s17.html

And actually, it seems pretty applicable. But there's one area where the
instructions aren't too useful, because they vary considerably from driver
to driver, and that's the connection pool MBean declaration. I'm thinking it
would look something like this...


   com.sybase.jdbcx.SybDataSource
   SybasePool
   ???
   user=dbusername;
password=dbpassword
   4
   10
   false
   120
   12
   false
   false
   true
   false
   false
   180
   1.0


But, I have no idea how to formulate the JDBC URL, or if it's even needed.
Also, I wonder if I need "JDBCUser" and "Password" attributes. All of these
things seem to vary from driver to driver. Has anyone set this up for the
Sybase JDBC driver? Any help is appreciated.

Thanks,
Jason

[JBoss-user] Followup - Joins - CMP Entity Beans - BUG????

[Vinay Menon]

Alright folks,
Here is the modified code. It works a treat!

  if (query.toLowerCase().startsWith(",")) {
  //Modified by Vinay Menon
  StringBuffer sqlBuffer = new StringBuffer();

  sqlBuffer.append("SELECT ");

  String primaryKeyList = getPkColumnList();
  String tableName = jawsEntity.getTableName();
  StringTokenizer stok = new StringTokenizer(primaryKeyList,",");

  while(stok.hasMoreTokens()){
sqlBuffer.append(tableName);
sqlBuffer.append(".");
sqlBuffer.append(stok.nextElement().toString());
sqlBuffer.append(",");
  }

 sqlBuffer.setLength(sqlBuffer.length()-1);
 sqlBuffer.append(strippedOrder);
 sqlBuffer.append(" FROM ");
 sqlBuffer.append(jawsEntity.getTableName());
 sqlBuffer.append(" ");
 sqlBuffer.append(query);

 sql = sqlBuffer.toString();
 //sql += strippedOrder +" FROM " + jawsEntity.getTableName() + " " 
+ query;
  } else



 Will take the trouble to actually modify the rest later! But if anyone 
wants to do it  please do. Also, if the code owners at jboss.org happen to 
see this - can you please ensure that a fix is in place for the next interim 
release??? - it would really help. I have currently rebuilt the source and 
am working off it.

Regards

Vinay

Hi Again,
Believe I have figured where the issue lies. The sql is constructed by 
org.jboss.ejb.plugins.jaws.jdbc.JDBCDefinedFinderCommand in the statement

 if (query.toLowerCase().startsWith(",")) {
  sql = "SELECT " + jawsEntity.getTableName()+"."+getPkColumnList() + 
strippedOrder +
" FROM " + jawsEntity.getTableName() + " " + query;


  Obviously, if getPkColumnList has multiple items, the table name would 
not be pre-pended!  Believe this is where the issue lies. Will try fixing 
this and recompiling the source. Might have to wait unitl tomorrow though 
cos its midnight!

Regards,

Vinay



Hi,
   Following the example provided in the online documentation I've tried 
getting the join working across 2 tables.

The table structures are

Table A
Col1,Col2,Col3

Table B
Col1,Col2,Col4

Col1 and Col2 form the primary key for both the tables.

The finder definition is

  
findForXXByYYZZ
,B
   WHERE B.Col1 = A.Col1
   AND B.Col2= A.Col2
   AND A.Col2= {0}
   AND A.Col1 = {1}


The sql that I'd wanted the finder to produce was

SELECT A.Col1, A.Col2
FROM  A,B
WHERE B.Col1 =  A.Col1
AND B.Col2=  A.Col2
AND A.Col2= {0}
AND A.Col1 = {1}

   The sql produced, however, seems to be

SELECT A.Col1, Col2
FROM  A,B
WHERE B.Col1 =  A.Col1
AND B.Col2 =  A.Col2
AND A.Col2= {0}
AND A.Col1 = {1}

Now Col2 is an ambiguous column and the query, obviously would fail.

Has anyone come across this and found a work around? Is anyone on the JBoss 
Developers list working towards fixing this?

Please do let me know

Kind Regards

Vinay Menon

OK, it's not posslible. It's a pitty that EJB actually seems to be

I'll do that then and hope, that this does't cost too much
performance. But I think it won't.

[JBoss-user] Getting a database connection using the jBoss connection pool

[Jennifer Labit]

All,

I need to be able to connect to my connection pool using something like
this:

DriverManager.getConnection("jdbc:xxx:yyy:MyPoolName")
...

What is the jdbc connection url that I would use to do that with jBoss?

I know the opinions on this list are that this isn't the ideal way to do it,
however, in this situation the database connection code needs to be
appserver independent and this is the best way to achieve that goal.

Thank you for your help.

org.jboss.ejb.plugins.jaws.jdbc.JDBCDefinedFinderCommand in the statement

 if (query.toLowerCase().startsWith(",")) {
  sql = "SELECT " + jawsEntity.getTableName()+"."+getPkColumnList() + 
strippedOrder +
" FROM " + jawsEntity.getTableName() + " " + query;


  Obviously, if getPkColumnList has multiple items, the table name would 
not be pre-pended!  Believe this is where the issue lies. Will try fixing 
this and recompiling the source. Might have to wait unitl tomorrow though 
cos its midnight!

Regards,

Vinay



Hi,
   Following the example provided in the online documentation I've tried 
getting the join working across 2 tables.

The table structures are

Table A
Col1,Col2,Col3

Table B
Col1,Col2,Col4

Col1 and Col2 form the primary key for both the tables.

The finder definition is

  
findForXXByYYZZ
,B
   WHERE B.Col1 = A.Col1
   AND B.Col2= A.Col2
   AND A.Col2= {0}
   AND A.Col1 = {1}


The sql that I'd wanted the finder to produce was

SELECT A.Col1, A.Col2
FROM  A,B
WHERE B.Col1 =  A.Col1
AND B.Col2=  A.Col2
AND A.Col2= {0}
AND A.Col1 = {1}

   The sql produced, however, seems to be

SELECT A.Col1, Col2
FROM  A,B
WHERE B.Col1 =  A.Col1
AND B.Col2 =  A.Col2
AND A.Col2= {0}
AND A.Col1 = {1}

Now Col2 is an ambiguous column and the query, obviously would fail.

Has anyone come across this and found a work around? Is anyone on the JBoss 
Developers list working towards fixing this?

Please do let me know

Kind Regards

Vinay Menon

In JBoss2.2+ there is a simple utility class that allows one to easily bind an
in memory object into JNDI. Look at the org.jboss.naming.NonSerializableFactory
code in the jboss cvs module for its implementation. Basically it just does this:

static HashMap wrapperMap = new HashMap();
Context ctx = whatever context you want, usually the InitialContext
String jndiName = jndi name relative to ctx
Object target = the inmemory object instance you want to bind
wrapperMap.put(jndiName, target);
// Bind a reference to target using NonSerializableFactory as the ObjectFactory
String className = target.getClass().getName();
String factory = NonSerializableFactory.class.getName();
StringRefAddr addr = new StringRefAddr("nns", jndiName);
Reference memoryRef = new Reference(className, addr, factory, null);
ctx.rebind(jndiName, memoryRef);

The NonSerializableFactory ObjectFactory implementation is:
public Object getObjectInstance(Object obj, Name name, Context nameCtx, Hashtable 
env)
throws Exception
{ // Get the nns value from the Reference obj and use it as the map key
Reference ref = (Reference) obj;
RefAddr addr = ref.get("nns");
String key = (String) addr.getContent();
Object target = wrapperMap.get(key);
return target;
}

RE: [JBoss-user] External Data Modification

[David Jencks]

Hi,
I can't tell all  the parameters of your situation.  If you are updating
individual rows of the database one by one, you should use commit option B
or C.  These are adapted for non exclusive access to the db by the ejbs.  I
think Daniel's solution is for when you are doing a batch update and want
to use commit option A for speed and then reload all the beans at once.

Hope this is relevant

Hi,

Sorry to bother you, I probably should be using a precompiled

Re: [JBoss-user] CORBA callbacks into JBoss

[David Jencks]

Hi,
I can't say I understand wxactly what you are trying to do, but the
following might be helpful anyway:

1.  Asynchronous messaging in java = jms spec + message driven beans,
implemented ( I think completely in jboss) as jbossmq ( formerly spydermq).
 Sending messages from beans may still be sort of by hand, but I think at
least one person was working on a JCA resource adapter for this.

2. As I understand it, jboss does not currently support rmi/iiop.

So if you can work around corba-jboss communication (avoid 2, or maybe I am
wrong), asynchronous messaging should be no problem.

Hope this helps and is relevant and correct.

StreamCorruptedException is propably because you have jBoss running on

Now not sure, and interested to know, does this mean that now 1.3

Re: [JBoss-user] Are readonly beans/transactions possible?

We noticed similar things and decided to change the transaction setting

So why not RMI/IIOP and interoperate Corba objects as RMI objects?  You get
to keep EJB/RMI and you get to speak CORBA.  JNDI, then can be your friend
for publication and rendezvous of service.  This is mho.

the unfortunate aspect of my situation is that the CORBA component is a)
being developed concurrently (and thus not being legacy) and b) the more
"definite" technology choice for the moment.  CORBA is a given (in fact, its
a standard for the piece i am integrating with); i need some sort of
application server mechanism to be able to provide a hot-deploy run-time
environment to interact with the CORBA piece.  part of me considers writing
a dumbed-down simple alternative to an EJB container as being the lesser of
two evils compared to trying to implement N x N callback proxying.

John,

I believe that we may have similar problems to solve from your brief
description below.  Our original solution was completely CORBA based.  I am
also interested in others comments in the area.  We are now rearchitecting
and taking a serious look as to why CORBA and why RMI.  The "why RMI" is not
hard since EJB RI is based on this model.  The harder question is RMI/JRMP
or RMI/IIOP?  But because CORBA can interoperate cross platform and language
and that some environments (Microsoft Exchange; Lotus Domino) may not be
friendly to a java based extension, we are forced into keeping both
technologies alive and happy.

We chose to divide and conquer.  Corba based services that are not subject
to rearchitecture can be made into MBean services instead of EJB.  Legacy
code that it is, it is still too daunting to rewrite everything to EJB all
at once.  It is not hard to make Corba services use RMI(through session
beans) much the same way servlets do.  The other way around, however, can be
done, but it is not trivial.

We also have leveraged greatly JNDI much the same way JBoss/EJB itself does
in both exposure and rendezvous of services through an open Naming
interface.  Both Corba and RMI can do this at different levels based on what
you actually require.  A simple way of doing this is to use JNDI as a Naming
Service for both RMI and Corba remote object.

This may not get you everything you are looking for, however, you may not
have to be forced into throwing out the baby with the bath water ;-)

Well your jboss.jcml looks ok as far as Oracle goes. Please check that you
actually can connect to that url with that userid/pwd with a tool like
jbcstest or something. The BindException has to do with the fact that you
have some other appl using same port as jboss (8083?). Or maybe you started

This is a valid desire, but the current state of security standardization
makes this undoable at this point. Even if an application server does
support JAAS there will be application server specific code to translate
from JAAS Subject to what the Subject state means in terms of the
caller principal and the principal roles because there is no standard for
how J2EE security can be implemented in terms of JAAS classes.

JAAS does not define the lifetime of logins because it depends on how
JAAS is used. In JBoss the ClientLoginModule operates in two modes,
single-threaded and multi-threaded. In single-threaded mode(the default),
the SecurityAssociation information is a VM singleton and the login information
lifetime is the lifetime of the JAAS login. Inside the JBoss server the
SecurityAssociation information is a thread local property and so a JAAS
login only affects the credentials of the thread in which the login was performed.

[JBoss-user] Are readonly beans/transactions possible?

[Sven Van Caekenberghe]

Hi all you jboss/ejb gurus,

While stress-testing an application using jboss we encountered some 
problems. We're not sure whether we did something wrong in the ejb 
development or in the deployment or what. We think we need at least some 
help in how to do 'readonly beans/transactions'.

Problem description:

System: jboss 2.2.x, interbase 6.x, jdk 1.3, linux mandrake 7.2
Server code: session bean facades working with multiple entity beans 
(some with subobjects)
Deployment: container managed persistence and transactions, requied 
transactions, default commit option A
Client code: swing gui clients, junit tests clients

Problem: Running more than one client we get locking-waiting, lock 
contention, but sometimes also failed transactions. The thing is that 
you would expect these problems when trying to modify the same object, 
but it also seems to happen when reading data from the same object 
(which of course happens a lot). It seems that even a call like 
PersonData[] getAllPersons() on a session bean (returning serializable 
copies of entity beans) needs full exclusive read/write locks on all 
objects involved in the transaction, even if we are just reading data. 
As we see it, such behavior will never scale.

Question: How do you do readonly beans or access beans in readonly 
transactions, either in ejb or in jboss? This must be a common 
situation. I hope the answer is not to avoid using entity beans for 
readonly data access and to access the database/datasource directly (we 
like cmp too much to let it go).

All help is greatly appreciated!

Sven

RE: [JBoss-user] EJB Question

[Daniel Cardin]

I am definitely not an expert on that topic, but I'd like to add my
comments :)

For one, beans have the advantage of running in the context of the
server. So you can assume that JBoss will manage security and
transactions if you so desire. This by itself is already worth
something, IMHO.

You have also access to all internal ressources like DataSources (not
available outside the context of the server). 
As well, if your session bean (implementing business code) needs to use
Entity beans, they could run within the same JVM. This sort of intra-JVM
type of communication is optimized in JBoss, so that calls that would go
through RMI are handled as normal method calls. (This is how I
understand it... hope it's correct :)) 

If you use stateless session beans, code can be pooled and reused by the
server to serve many clients in succession. 

This is not very complete, but I see those points as good reasons to use
SB vs. non EJB code. But as always, there is a good place for every bit
of code. Session Beans (stateless) are normally used to implement
business code. 

Hope it's a little bit informative :))

Daniel

ps. If I was wrong on any of this, please tell me :) I'm still learning.
Thanks!

Well your jboss.jcml looks ok as far as Oracle goes. Please check that you
actually can connect to that url with that userid/pwd with a tool like
jbcstest or something. The BindException has to do with the fact that you
have some other appl using same port as jboss (8083?). Or maybe you started
jboss twice?

So why not RMI/IIOP and interoperate Corba objects as RMI objects?  You get

John,

I believe that we may have similar problems to solve from your brief
description below.  Our original solution was completely CORBA based.  I am
also interested in others comments in the area.  We are now rearchitecting
and taking a serious look as to why CORBA and why RMI.  The "why RMI" is not
hard since EJB RI is based on this model.  The harder question is RMI/JRMP
or RMI/IIOP?  But because CORBA can interoperate cross platform and language
and that some environments (Microsoft Exchange; Lotus Domino) may not be
friendly to a java based extension, we are forced into keeping both
technologies alive and happy.

We chose to divide and conquer.  Corba based services that are not subject
to rearchitecture can be made into MBean services instead of EJB.  Legacy
code that it is, it is still too daunting to rewrite everything to EJB all
at once.  It is not hard to make Corba services use RMI(through session
beans) much the same way servlets do.  The other way around, however, can be
done, but it is not trivial.

We also have leveraged greatly JNDI much the same way JBoss/EJB itself does
in both exposure and rendezvous of services through an open Naming
interface.  Both Corba and RMI can do this at different levels based on what
you actually require.  A simple way of doing this is to use JNDI as a Naming
Service for both RMI and Corba remote object.

This may not get you everything you are looking for, however, you may not
have to be forced into throwing out the baby with the bath water ;-)

[JBoss-user] MBean access via JNDI - How to?

[Coates, David]

I have a custom MBean that adds a service to my JBoss container.  Now I want
to be able to control that MBean/service from an EJB.  For example send it
start(), stop(), restart(), or getStatus() messages.  My basic goal is to be
able to provide a web interface for my users so that they can monitor the
service that the MBean provides, as well as shut it down, restart it, etc...

I see that the documentation says that the best way to make an MBean
available to your EJBs is to make it available via JNDI.  What is the best
way to do this?

Obviously, I need the EJBs to interact with the original instance of my
MBean and not a copy of it recreated via serialization.  So is it possible
to use javax.naming.Reference and just bind that to the JNDI tree, or do I
have to set up a RMI registry and bind an entire registry to JBoss's
existing JNDI directory, or what?

I'm using jboss-2.0-FINAL bundled with Tomcat, running on a Win NT box.

No, that's awful advice.

You need an entry in your ejb-jar.xml that declares the resource manager
reference "inetbankDB".  Then you need to link that to your actual datasource
using jboss.xml.

Then you use "java:comp/enb/inetbankDB" in your bean code.

This is in the EJB spec, see section 19.4.  The jboss.xml part is not very
thoroughly documented, but the DTD is simple enough to follow.

You are missing the other part of jboss.xml that you need.  There is an
extra indirection.  I can't recall the exact details, but this has been
explained *many* times on this list.

Not relevent unless you're using CMP.

RE: [JBoss-user] External Data Modification

[WMckean]

Hi Daniel:

Thank you for the quick response.  I currently have a jBoss based product
supporting 50 internal customer service reps.  The beans report on things
like balances and such, and they need to be up to date.  The cache manager
you are talking about, is it a customer manager you wrote, or one integral
to jBoss?  I need to work something out until I can get my external
processes to use SOAP :) which I'm off to SOAP land now...

Wes

BTW:  We need to write a SOAP RPC compiler which takes a EJB remote
interface and compiles the client automatically, like rmic.  If anyone knows
of such a compiler, let me know.

BTWW:  I have written an ant task to which automatically rebuilds jboss.xml
and ejb-jar.xml so the whole project can be built and deployed from ant.  If
anyone is interested, let me know and I will send the source code and a
sample to the proper place.  It isn't complete, but it is nice rebuilding
entire JAR/WAR files from scratch with one command.

Hi Wes :)

There is a thread that we started not too long ago on the topic. The way
we have handled it is by creating our own instance of a cache manager
for JBoss that is able to mark beans as dirty (thus are reloaded through
ejbLoad on the next call). We have JMS setup so that our "traditionnal"
application posts messages to the cache manager when making changes.

A similar approach could be taken using triggers in the tables concerned
I think... As long as your database allows you to call on external
functions in triggers (as MS SQL does).

Feel free to ask more questions if you aren't sure what the heck I'm
talking about :)

RE: [JBoss-user] CORBA callbacks into JBoss

[Sam]

John,

I believe that we may have similar problems to solve from your brief
description below.  Our original solution was completely CORBA based.  I am
also interested in others comments in the area.  We are now rearchitecting
and taking a serious look as to why CORBA and why RMI.  The "why RMI" is not
hard since EJB RI is based on this model.  The harder question is RMI/JRMP
or RMI/IIOP?  But because CORBA can interoperate cross platform and language
and that some environments (Microsoft Exchange; Lotus Domino) may not be
friendly to a java based extension, we are forced into keeping both
technologies alive and happy.

We chose to divide and conquer.  Corba based services that are not subject
to rearchitecture can be made into MBean services instead of EJB.  Legacy
code that it is, it is still too daunting to rewrite everything to EJB all
at once.  It is not hard to make Corba services use RMI(through session
beans) much the same way servlets do.  The other way around, however, can be
done, but it is not trivial.

We also have leveraged greatly JNDI much the same way JBoss/EJB itself does
in both exposure and rendezvous of services through an open Naming
interface.  Both Corba and RMI can do this at different levels based on what
you actually require.  A simple way of doing this is to use JNDI as a Naming
Service for both RMI and Corba remote object.

This may not get you everything you are looking for, however, you may not
have to be forced into throwing out the baby with the bath water ;-)

Subject: [JBoss-user] CORBA callbacks into JBoss


hello list:

one of the reasons that i want to use an application server such as JBoss is
to take advantage of the runtime environment that EJBs provide, particularly
the pooling and scaling aspects of EJB. also, the hot deploy mechanism is
much valued in the run-time scenarios i am looking at.

however, one of the pieces that i wish to integrate with has a CORBA
interface and supports a callback model. some CORBA calls will be
synchronous, while others will have at least one (if not several)
asynchronous callbacks into EJB land. this seems like a bit of a misfit,
unfortunately.

the only scenario that i can see possibly working is to proxy the external
CORBA interface into some kind of layer that manages the EJB callbacks. at
first glance i do not see, however, how this would allow for easy scaling
the way that EJBs inherently allow. also, it appears to require a lot of
knowledge about the EJBs trying to use the CORBA in order to resume the
callbacks.

does anyone have any suggestions for me? is this scenario too ill fit for
EJB?

Yes I read it, but what I don't like about that solution is that one
has to reconfigure Tomcat. Now I have the application almost in the
stage where you can just throw an EAR into the deploy directory and
it's done. I'd like to keep this. But there are only two servlets
which handle all the incoming requests, so I can easily do the same
without a RequestInterceptor. The other (and more important) point is
that the application doesn't use any JBoss classes up to now, so it
should be possible to run it on any EJB server with JAAS security by
only rewriting the deployment descriptors. That's the other thing I'd
like to keep.

As mentioned above, I'm in the happy situation that there are only two
servlets that dispatch *everything*. So that's what I'll do now: I
login at the beginning of the init() and service() methods and logout
in a finally block. Will this work as expected?

But the principles of how JAAS works there are still very indistict to
me: In my client (admin) application I do the login in a separate
thread. If logins are bound to threads, my client app should not work,
because after a successful connection, the thread that logged in
doesn't exist anymore. That's why I though the scope of a LoginContext
is the whole JVM. I searched the internet for information about the
scope of a LoginContext, but I didn't find anything. It would be great
if you could clear this up a bit...

Re: [JBoss-user] Get Database connection from Jndi

[Guy Rouillier]

If you read the javadocs for javax.sql, you'll see that all the interfaces
there (except the event classes for some odd reason) are abstract.  So
javax.sql doesn't provide a connection pooling ** implementation ** - it
defines only an interface.

The pooling implementation shipped with JBoss is called minerva.  You can
use this outside of JBoss (uses the JBoss hierarchy, so you will need the
JBoss classes, but you won't need JBoss running.)  Also, there are several
open source database connection pool libraries available if you can't get
minerva to work for you.

[JBoss-user] Bulk update of entity beans from a session bean

[Sita Raman Singh]

Hi,
I've an application where I need to implement item by item and bulk
updating of entity beans ie in some cases only a few entity beans are
getting modified and in other cases a very large no of entity beans are
getting modifed.

I intend to use commit-option A and since JBoss has pessimistic
concurrency control (one-instance-per-pk and Serialized call I learnt) ,
I am thinking of implementing bulk update of entity beans as follow for
performance reasons.

1. use a BMT session bean and start transaction
2. update all records in the database
3. findByPKs() all entity beans
4. call a business method say, populate() on each entity bean and inside
this method update the state of entity bean. Although this method sets
the state of the bean it doesn't mark that bean as modified and hence
IsModified() method return false (hence it will not be stored again)
5. commit the transaction.

Please comment from a developmental prospective if it will work? What
are the flaws ? Is there any other preferred way to do it ?

Regards,
SRP

No, the UsernamePasswordLoginModule is typically used by the security domain
protecting your EJB to validate a username and password that has been
sent by a client. Your servlet(s) are the EJB clients that have to provide an
identity in order to access your secured EJBs.

Tobias Seeligner mentioned a better solution to having the user credentials passed
to JBoss EJBs. He created his own Interceptor that performs the binding of the
guest username and password using the SecurityAssociation class I mentioned.
This avoids having to have a JAAS login in your servlet request method and also
isolates the JBoss code to the Interceptor for use by all unsecured servlets.

No, logins have to be done in the thread that is making the request. Since your
an EJB client that is a multi-threaded server, you have to establish the client
identity on each request since you have no control over how thread pooling
assigns threads to servlet requests.

As pointed out by Vincent Harcq, it can be a problem with beta3. Can you try
the latest nightly build ?
Also, can you post the code of your servlet/jsp where you call EJB1 and EJB2

[JBoss-user] CORBA callbacks into JBoss

[John Camelon]

hello list:

one of the reasons that i want to use an application server such as JBoss is
to take advantage of the runtime environment that EJBs provide, particularly
the pooling and scaling aspects of EJB. also, the hot deploy mechanism is
much valued in the run-time scenarios i am looking at.

however, one of the pieces that i wish to integrate with has a CORBA
interface and supports a callback model. some CORBA calls will be
synchronous, while others will have at least one (if not several)
asynchronous callbacks into EJB land. this seems like a bit of a misfit,
unfortunately.

the only scenario that i can see possibly working is to proxy the external
CORBA interface into some kind of layer that manages the EJB callbacks. at
first glance i do not see, however, how this would allow for easy scaling
the way that EJBs inherently allow. also, it appears to require a lot of
knowledge about the EJBs trying to use the CORBA in order to resume the
callbacks.

does anyone have any suggestions for me? is this scenario too ill fit for
EJB?

Hey,

Catalina comes with its own naming implementation, that is by default
active.
So if you have code under web-inf/lib or web-inf/classes that does new
InitialContext(), even if a jndi.properties is in the web application
classpath (pointing to a different naming service than the Catalina one),
Catalina get confused and barfs unknown protocol: jndi

Since JBoss has its own naming service, you should probably start Catalina
with the -nonaming option.

I didn't try Catalina with JBoss, but with another application I wrote (that
has its own naming service), the -nonaming option did the job. Probably will
do also for JBoss, but I'm not 100% sure of this.

Let us know.

HTH,

Simon

[JBoss-user] Many threads in JBoss java VM

[Richard Conway]

Whilst testing our website with approx. 40 users I noticed that the JBoss
java process had about 110 threads. This struck me as quite a lot - my main
concern being how the system will scale with more users.

Are there any practical limits to the number of threads in a java virtual
machine. For example, does the performance of the VM degrade when there are
too many threads.

Is there an alternative JBoss configuration which would help - eg. using
serveral JBoss processes in some sort of load-balanced cluster (as can be
done for Tomcat).

We are using Sun's Java Hotspot Client VM (build 1.3.0-C) on a Solaris 2.6
platform.
The JBoss version is '2.0 FINAL'.

Any help much appreciated ?

Richard.

You can 'preoptimize' jars that you install as well. Don't remember the

Start your jboss server.

Build the tests - using the scripts in src/build

Run the tests - using the ant file run_tests.xml

Or using the GUI version of junit in dist/bin - I think...

Feel free to post patches to sourceforge to sort out the few that don't
work.

[JBoss-user] custom finders with MS SQL Server

[Cumps Jef]

Hi, 

I am developping a bean called RoadDataBean and I am writing some custom finders for 
it. The data is stored in an SQL-Server database, dates are stored as long's.

The finder I'm working on, is as follows: 

public interface RoadDataBeanHome extends EJBHome
{
  ...

  public Collection findBetweenDates(String id, long startDate, 
 long endDate) throws RemoteException, FinderException;
}

In the file jaws.xml, I have put the next: 


 

RoadDataBean

findBetweenDates
wc_id = '{0}' and date between {1} and  
  {2}
rd_id asc


true
true 



When i try to call the finder, i get a FinderException, and i can't figure out why !!

I checked the sql-statement, it's ok. I thaught maybe the exception tells me that the 
resultset is empty, but it isn't, i checked !?!?

CAN ANYONE HELP ME ??? Do you have experience with custom finders? An example that 
works for MS SQL Server? Any hints or tips?

Any help would be really appreciated !!!

thanks in advance, Jef

RE: [JBoss-user] JMQ question

[Taylor, Richard]

I've followed the Sun tutorial on this and it waas very helpful.  Take a
look at http://java.sun.com/jms/tutorial

The only problem I came up against was the JNDI name for the queue or topic.
The tutorial says to connect to QueueName or TopicName but in JBoss you have
to connect to queue/QueueName or topic/TopicName.

Just one more things concerning debugging with VAJ...

In my case, debugging wasn't always working in VAJ. I had to modify

[JBoss-user] DataSource bound to wrong database with stateless session bean

[Nguyen Thanh Phong]

Hello,

I think I have made something totally wrong but don't know what is wrong.
Please help.

I have configure DB2 to be bound to java:/DB2DS.

In my ejb-jar.xml, I have


  jdbc/IdGeneratorDS
  javax.sql.DataSource
  Container


In my jboss.xml, I have

  
jdbc/IdGeneratorDS
java:/DB2DS
  

In my standardjaws.xml I have


java:/DB2DS
DB2
true

However, when I test my bean bean, I saw that it use a connection to the
DefaultDS, which is the HypersonicDB as preconfigured with JBoss (see trace
below).

Strangely, if I configure my DB2 to be bound to DefaultDS, everything
works!!!

Any helps are greatly appreciated.

Phong.

Re: [JBoss-user] EJB Debugging in jBoss?

[Wei Jiang]

You can trace instead of debug.
Trace can be on and off on production, but debug can not.
SuperLogging allows you do source code level trace.

Try SuperLogging of Super from www.acelet.com.
It is free for open source (Jonas, jboss and j2ee-ri).
Evaluation edition is free for other servers.

SuperLogging is a full-featured logging tool:

 * It is a centralized logging, guaranteed tobe chronolotical.
   It supports distributed computing and works well in any 
   clustering environment. all log messages are recorded in 
   one central place regardless which EJB runs on which 
   server. 

 * It is platform neutral and EJB vendor neutral. 

 * All log statements used in the source code do not need be 
   removed for production releases.  Log messages can be 
   dynamically filter out and the performance penalty will be 
   minimum. 

 * An open source wrapper com.acelet.opensource.logging.Alog is 
   provided for preventing vendor lock in.  Source code of EJBs 
   is not required for any modification if another logging 
   packages is chosen. In that case,  the only modification 
   needed is this wrapper, which is just a few lines of code. 

 * It is fully dynamically configurable by a Swing tool. The 
   configurable attributes include the following: 

 * Choice of configuration scope: Global Dynamic, Global Static 
   and Singleton. 

 * Choice of mode: Quiet, Verbose and Conditional. 

 * Class registration: log messages will be printed out for 
   registered classes only. 

 * Log level: lower level log requests will be filtered out. 

 * It provides Tracing facilities which show both log messages 
   and source code with marked line in question. 

 * It provides built-in email alert method and alert interval 
   control. 

 * It provides email methods which allow sending email by a 
   simple method call.

RE: [JBoss-user] EJB Debugging in jBoss?

[Sacha Labourey]

Hello,

Please read the JBoss manual (!)

There is an how to on how to debug beans from VAJ. But I admit it, it is not
easy to find it as it is labeled:

"How to Run and Debug EJBs using jBoss 2.0 inside of Visual Age for Java
version 3.5"... :)


Furthermore, read the JBoss ML archives: another user suggested a simpler
method by importing a pre-built VAJ project including all needed setup.

Cheers,




Sacha
