Shouldn't you just filter "/*"?

Re: tapestry-acegi, how does SecurityUtilsImpl.accessDecisionManager get set?

[James Carman]

No, you're looking at a different module entirely.  The tapestry-acegi
module relies upon the hivemind-acegi (usable in non-tapestry projects)
module to set up the core Acegi stuff.

I don't know.  Would the enhancement workers allow you to enhance a field

Re: plugins for a tapestry app?

[James Carman]

There's a HiveMind module for that, actually.  Check out:

http://svn.javaforge.com/svn/hivemind/hivemind-hibernate3/trunk/src/main/resources/META-INF/hivemodule.xml

That's my hivemodule.xml file and it basically just sets up a
configuration point that allows any HiveMind module to contribute to
the Hibernate configuration.  It works great in our application,
allowing us to just drop in new parts of the "domain" model and they
just get added into the mix automatically.

Re: plugins for a tapestry app?

Since HiveMind is already integrated with T4, I'd say use it.  It has
the ability to dynamically discover new modules like you're wanting.
I came up with a similar architecture to allow multiple modules to
contribute to my Hibernate configuration dynamically.  All you had to
do is drop in the jar, and the entities were automatically picked up

Re: T5 + Jetty + Hibernate

That's not exactly a good separation of concerns, though.  Your view
layer shouldn't be talking directly to your ORM layer.  I'd put a DAO
layer in between for some encapsulation (and to help with unit
testing).

Having an hibernate Session injected into T5 pages is fairly easy:

public final static SessionFactory buildSessionFactory()
{
URL res = AppModule.class.getResource("/hibernate.cfg.xml");
SessionFactory sf = new AnnotationConfiguration()
.configure(res)
.buildSessionFactory();

return sf;
}


@Lifecycle("perthread")
public Session buildSession(@InjectService("SessionFactory")
SessionFactory factory)
{
return factory.getCurrentSession();
//return factory.openSession();
}


Then in you page just:

  @Inject
  private Session _session;

I think all of these is explained in the online doc.

If you need/wish more integration (like having your hibernate object
directly into your pages) you have to do some more work, this is just
a starting point.

Re: tapestry-spring lazy initialize everything?

Just omit the setting.  If hibernate doesn't see

Re: tapestry-spring lazy initialize everything?

[James Carman]

Can you just mark your session factory bean as lazy init in your
spring application context file?  Or, mark the whole xml file as lazy
by default?

Re: OutOfMemoryError after serving N pages

[James Carman]

Are you disabling page/component class caching?  Of course, I think
that causes the permgen stuff as mentioned before, but it may be part
of your problem.

On 2/22/07, Joe Trewin <[EMAIL PROTECTED]> wrote:

If you're using Tomcat and have access to the startup scripts, I'd
suggest turning on JMX so that you can have a look inside the memory
heaps using jconsole.

To do this add a line to tomcat/bin/startup.sh just before the exec at
the end:

export CATALINA_OPTS="-Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.port=9098
-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.authenticate=false"

(Note that this assumes an internal dev box, as there's no ssl or
authentication turned on.)

You can then connect to it with jconsole (in your java install's bin
directory).

The next step would be some more automated profiling, but just visually
looking at the state of the heaps during a load test can be quite
helpful.

Re: Record locking

[James Carman]

You use the session id so that you don't maintain the reference to the
actual session.  When the session listener sees that the session dies,
he removes all object locks for that session.  Now, this still doesn't
solve the problem of one user opening multiple windows and trying to
edit the same object, but if they're that stupid, then they deserve to
lose their work (kidding of course, but just wanted to point out the
issue).

Re: Record locking

[James Carman]

If the browser dies, then the session will timeout.  The record will
not stay locked (if you just keep an in-memory record of who is
editing what).  You could use a "do you want to save your changes"
notification (a la GMail and others) to either save the data or send a
request to clear the lock when they leave the edit screen.

Re: Record locking

[James Carman]

The suggestion of using the http session (its id actually) was pretty
cool I thought.  That allows you to "timeout" the checkout/lock.  You
need to make sure (as pointed out) that the locks don't get orphaned,
thereby locking everyone out of the object/record perpetually
(obviously you could write an admin screen to unlock it).

On 2/20/07, Barry Books <[EMAIL PROTECTED]> wrote:

Murray,

I also have records that need to be 'checked out' for some time and
your solution seems simple and elegant. So much so I may steal it.

I use one sequence for every primary key in the database so a table
named "lock" with

key primary key
timestamp timestamp
userid

should do it. UserId lets me know who has it.

to see if a record is locked and get lock key

select count(*) as locked, key, timestamp from lock where key = ? and
timestamp less than 20 minutes old group by key, timestamp

1 is locked 0 unlocked timestamp is the key to lock the recored

to lock a record

if key == null
insert into lock values ( key, now, userid)
else
update lock set timestamp = now, userid = ? where key = ? and timestamp = ?

if you update 1 row you've got it otherwise someone else does

to unlock

update lock set timestamp = null where key = ? and timestamp = ?

if you don't get 1 row updated something bad happened

Seems easy. Records are locked a max of 20 minutes and no races I can see.

Yes, javassist is the culprit for that part of the problem. Exchanging

That will allow it to actually deploy the war file without errors.

This stacktrace is on osx - on windows it actually also says
(permission denied) with the FileNotFoundException.

Does anyone have any idea on how to get around this?
All these errors are replicateable with any minimal tapestry 5
application (try the tapestry-simple maven2 magic) on a standard
jboss, and thus we should try to find a solution. Also, my deadline is
tomorrow ;)

Re: Record locking

[James Carman]

Just use the session id and set up an HttpSessionListener to remove
user's locks when their session expires.

One has to be careful with this approach, because the checkout must,
somehow, expire, otherwise you risk leaving an object permanently
uneditable if a client gets disconected/forgotten/whatever.

Just throwing random ideas about: How about making the 'checked-out'
property a weak hash, pointing to the editing user's session (or some
attribute within)? I assume the J2EE container will GC expired sessions,
thus automatically expiring the object's check-out.

I would say just put a property on the object that says that it has
been "checked out" or something.  That way, you can tell a user that
tries to edit it that they can't because "so and so has this record
checked out and is editing it."

Just out of curiosity, can you tell more about your use case? I just have a

rather I'd assume it's something specific to a type of a record. And if it's
the latter, I'd just implement it in the application level along the lines
you'd suggested. But I'm not sure I'd call it locking, which I understand as
a database feature for enforcing atomic transactions. It'd be fairly easy to
implement the checking and enforcing of your edit rule in a Hibernate
Interceptor. For obtaining the application level "lock" you can use
optimistic locking; this is sort of the same as doing svn lock.

Re: T5: Spring Integration

I think what is needed, though, is something that allows you to bind
spring beans directly into your page/components.  Having to lookup
spring beans all the time can be a pain.

We're actually thinking of using Bamboo at work, so if you find that

Re: Record locking

[James Carman]

You can use optimistic locking.  When the user submits and they have
outdated data, then you just merge the object's data with what is in
the data store and show it back to the user for them to confirm it.

On 2/19/07, Murray Collingwood <[EMAIL PROTECTED]> wrote:

This is a rather simplistic answer, however I have been away and read the
documentation and am not convinced that this is providing a method that will
warn a user if somebody else if already updating a record.

Even this example of pessimistic locking appears to allow for previous data
changes to be overwritten:
http://forum.springframework.org/archive/index.php/t-10188.html

What would convince me?

An example of a read-for-update operation that returned a condition (or
exception) indicating that the requested object was currently locked by another
user.  I'm yet to find that in Hibernate.

If you want to use Jetty 6 then you can't use the plugin, but you can

import org.mortbay.jetty.handler.DefaultHandler;

import org.mortbay.jetty.webapp.WebAppContext;

public class JettyLauncher {

public static void main(String[] args) throws Exception {
String path = (args.length > 0 ? args[0] : "web");
Server server = new Server();

Connector connector = new SelectChannelConnector();
connector.setPort(8080);
server.setConnectors(new Connector[] { connector });

HandlerCollection handlers = new HandlerCollection();
ContextHandlerCollection contexts = new
ContextHandlerCollection();
handlers.setHandlers(new Handler[] { contexts, new

server.setHandler(handlers);

new WebAppContext(contexts, path, "/");

You could run mvn jetty:run to fire up your application in Jetty.  It

Thanks James

Adding the tapestry-spring.jar file to the other jars solved the problem.  I
kind of assumed anything with Tapestry in the name would be downloaded in a new
version.

Next problem:

My first page now appears but I get these error messages appearing at the end:

I'm getting really frustrated with Eclipse.  I started by adding a user
library called Tapestry411 and placing all of the JARs in this user library.
Eclipse would say that it was publishing the application but the user library
was never copied over.

So, I moved all of the jars to the WEB-INF/lib folder in my development area,
however Eclipse doesn't recognise the WEB-INF/lib folder as a library of jars
and so it reports all of these errors that it can't find classes.  So I left all
of the jars in the WEB-INF/lib folder in my dev area and created a user library
that located the jars in the WEB-INF/lib folder (I feel like I'm jumping through
hoops because Eclipse isn't working like it should).  Finally I publish the
application and everything gets copied except for the jars.  I start tearing my
hair out at this point.

In utter frustration I then manually copy all of the jars into the WEB-INF/lib
folder of the server.

The server now starts up without any obvious errors.  When I try to use the
application the above error occurs (before the first screen is displayed).

Re: Migration to Tap4, accessing the hivemind registry without injection

That's one thing that I don't understand about the Spring community.
They are very skeptical to use autowiring.  They suggest specifically
wiring up your beans (at least the experts I've heard suggest that).
Anyway, for the applications that I write, there is usually only one
service that implements a given business interface (like a DAO or
something), so it's no big deal.

Re: Migration to Tap4, accessing the hivemind registry without injection

[James Carman]

No problem.  I think the property "injector" code works by enhancing
(extending) your page/component classes and implementing the
getter/setter methods.  But, it should complain that your
getters/setters aren't abstract, I would think (it does in other
cases).

The thing I like most about the tapestry-autowire stuff is that all
you have to do is drop the jar file into your WEB-INF/lib director and
it just works!  No configuration necessary.

Re: Migration to Tap4, accessing the hivemind registry without injection

[James Carman]

The tapestry-autowire will look for abstract "getters" and it will
implement them for you if it can (by finding exactly one hivemind
service which matches the type).  In your case, it seems like you've
got quite a bit of work on your hands.  I'd consider putting the
abstract getter in your base page class (most people have a base
page/component class that they extend).  Then, look for all
implementations of that method and remove them.

Hello

Thanks for your answer,
But tap4.1 seems to need java 1.5 and I am restricted to java 1.4.
So any library dependant of java 1.5 can't be used.
If the service point is in module "com.mymodule" and is called
daoFactory , and if I have an abstract method getDAOFactory, it will
be autowired without any annotation or anything?  If true that would
be amazing!

Also I have faced a new problem:
I have migrated .page and .jwc to tapestry 4 DTD (using XSLT), using
the  has changed
quite a lot.  In tap 3 I used that instead of initialize() to handle
transient properties and correct initialization.
In my code I have two methods NON ABSTRACT getMyProperty and
setMyProperty and a private variable myProperty.  Those methods seems
to never be accessed?
It seems that the property binding overrides my methods definitions!!!?
Do you know how to avoid this, because initialize() method in the
page seems to be deprecated, and i don't want abstract methods.
Do I have to go through all my pages to find properties that are
defined in the .page and which are not abstract ?
What can I do ?

Thanks A lot

Re: Custom annotation

[James Carman]

What version of Tapestry?  If you're on 4.x, you can look at what I
did in tapestry-acegi, which looks for the @Secured annotation on
methods/classes.

http://svn.javaforge.com/svn/tapestry/tapestry-acegi/trunk

The login is anonymous/anon

Re: Migration to Tap4, accessing the hivemind registry without injection

[James Carman]

By the way, there has to be exactly one service point which is of the
type that you need injected in order for it to be autowired, but
that's traditionally the case when it comes to DAOs.

Re: Tapestry & Hivemind: Caching multiple method calls per request?

[James Carman]

Tapestry would have to know what's inside the method to know that it
will always return the same thing.  This method doesn't return the
same thing all the time:

public String getTimestamp()
{
 return String.valueOf( System.currentTimeMillis() );
}



On 2/9/07, Tobias Marx <[EMAIL PROTECTED]> wrote:

Indepenent of what the method looks like, why is it called more then once 
anyhow?

If there is the same method inside a page or component, I thought Tapestry retrieves all 
the data first and then "intelligently" parses all the pages and its component 
templates and notices if the same method is called several times?

Now it seems like it goes through all templates line by line and then calls the methods 
every time it encounteres them without "an eye" for the page scope?

If I define a class as threaded in Hivemind, doesnt Tapestry "know" that the 
method will always return the same result if it appears 100 times inside a page or 
component?

If there is an injected method in some components and pages that references a 
threaded Hivemind class.it is always the same call and therefore Tapestry 
would only need to call it once and use the same result for all components?


Thanks!

Re: Tapestry & Hivemind: Caching multiple method calls per request?

[James Carman]

What does the method that fetches the domain object look like?  Does
it cache its results or does it call the IDomainSource every time?

On 2/9/07, Tobias Marx <[EMAIL PROTECTED]> wrote:

Hi there!

I am using Hivemind to generate a Map of Domain name related objects as a 
singleton on startup, called HibernateDomainSource.

Then I am constructing a threaded services that uses this data
together with the servletRequest. This service is called DomainManager.

I am now injecting the DomainManager into my base component in order to access 
a domain object from the HibernateDomainSource that corresponds to the domain 
name from the servlet Request.



















The "problem" now is, that the DomainManager method that fetches the domain 
object from the map is called several times during a single page request.

Is there a way to force it to only fetch it once per page request?

Re: [very OT] group conventions for people use testng?

[James Carman]

Have you tried -excludegroups ?
I think that works.

I think if I was building an application, I may add additional groups

I wish TestNG had an option to exclude named groups from a run, and
run everything else (including those outside a group).  T5 core now
has 689 tests and takes nearly a minute to run. On the other hand,
most of that time is spent inside integration tests and without those
I don't really trust that the framework operates correctly so there's
no way to win!

At this point, i've already got:

- page creation wizard.
- syntax highlighting in component templates.
- a visual palette that show all services in you module builder in a

documentation from the service class and shows it in a nice manner.

Still a lot to be done and lot's of cool ideas in my mind. The really
good news is that implementing this has been much much easier compared
with supporting T4.

Re: Aspects in tapestry pages using spring

[James Carman]

Well, it depends on your pointcut, I guess.  If it can be woven into
your code properly, you don't need to recompile Tapestry.  However,
you might want to look into putting an interceptor on the page service
or introducing a web request servicer filter.  That's an easy way to
do cross-cutting concerns.

On 1/26/07, Denis McCarthy <[EMAIL PROTECTED]> wrote:

Thanks for that James. I've got the aspectj stuff working now. The
reason why I've been looking into aspectj is to log the length of time
users of my site spend on individual pages. I want to log when each page
is rendered for a particular user's session, giving me a record of how
long a user spent on any individual page (this information is important
to me because the application is a touch-screen application, and if any
screen is slowing down or frightening users away because of its
complexity I want to know about it)


As this is a stereotypical cross-cutting concern, I've been looking for
a nice way to log this using tapestry's own internals. However, if I
understand aop correctly I'll have to compile tapestry itself using ajc
with my aspect to weave the aspect into the tapestry code. This could be
a little over the top - I'm wondering is there some less invasive way to
record page loads per session without resorting to copying and pasting
the same code into every page to accomplish this? Is there something in
hivemind that'll allow me to record this information?

Re: Aspects in tapestry pages using spring

[James Carman]

You can also use AspectJ within Tapestry using hivemind-aspectj (at
JavaForge).  You still have to make sure you weave the aspects into
your code, but hivemind-aspectj can inject HiveMind services into your
singleton (the default) AspectJ aspects.  That way, you can inject all
of Tapestry's HiveMind goodies into your aspects in case you need them
(which you probably will).  If you want more information, email me
back and I'll see if I can give you an example (the test cases are
quite slim, but they do show how it's used).

Re: Acegi and Visit object

[James Carman]

By the way, you don't *have* to implement your UserDetailsService
inside a Spring container.  You can do so, but you lose the easy
ability to have other HiveMind services automatically injected into
your implementation instance.  Since you're just implementing an
interface, I really see no need to have it as a Spring bean (I don't
use the Spring container at all in my applications, though, so I am
biased I guess).  To do it using HiveMind, you'd use the
BuilderFactory (the default) to build your implementation object
rather than the SpringLookupFactory.

You have your own org.acegisecurity.userdetails.UserDetailsService and want

Here is an example how to do it. First we need a Spring bean for that
UserDetailsService (in your applicationContext.xml)
 

 
(That replaced the "memoryAuthenticationDao" from my example.)

We reference this bean in hivemodule.xml

James, it was useful for me to have the hivedocs for the tapestry.acegi and

Re: Acegi and Visit object

[James Carman]

Basically, tapestry-acegi just allows you to glue all of the Acegi
stuff together using HiveMind, rather than Spring (it's all just
"object soup" right?).  Actually, the majority of the configuration of
the services goes on outside of tapestry-acegi itself (it's in
hivemind-acegi and hivemind-acegi-dao, so it can be used in a
generalized fashion).  The cool part of tapestry-acegi is that it lets
you use Acegi's @Secured annotation (found in the acegi-tiger jar
file) to annotate your listener methods and page classes so that you
can declaratively secure them to specific roles.  As for examples, I
don't really have one, but somebody wrote a nice Wiki page detailing
how to set it up.

Hi James,
We are about to implement Acegi to our application and we are using Spring
2.0.2, Hibernate 3, Tapestry 4.02.
Are tapestry-acegi.jar a replacement for doing the Acegi mappings in Spring?
What do we need to configure to make it work? If you could give some example
that would bee really nice

Thanks a lot

Re: Page Visitor IP Address/Port

You can also include tapestry-autowire.jar into your application and
have Tap automatically inject it by doing (no annotations necessary):

public abstract HttpServletRequest getServletRequest();

Also, the port is available on the request.  Try getServerPort().

I don't know how to get the port. (And also this IP-address

Re: New Tapestry feature suggestion: EditForm generation

That was my idea and I haven't really seen any development going on

Re: Recommendation...

[James Carman]

The tapestry-acegi allows you to use Acegi's @Secured annotation
(declarative security) in Tapestry without the Spring container.

I am very happy using Tapestry for the WEB portion of my application
and Spring 2.0 to wire up and configure my beans and do all the other
stuff spring does. I especially like using spring with the Spring
Annotations addon. There is some overlap between Tapestry and Spring
in that tapestry uses it's own IOC container called Hivemind. While
hivemind and spring share many features in the wire-your-beans up
department spring's has many additional features unrelated to bean
wiring (such as Acegi Security for example). The only thing spring
doesn't seem to have is hiveminds hierarchical configuration where you
can define configuration points that get configured differently
depending on which jar you drop in. This is kind of neat and I wish
spring did that.

If you're referring to the persistence strategies, then you're limited
to wherever Tapestry uses the persistence strategies
(pages/components).

When the async property is set to false, my page is displayed without

It seems that the DojoAjaxResponseBuilder bypass the OpenSessionInView

Is it a normal behavior for the Ajax requests ?

Re: Extending existing component and .page file

[James Carman]

What are you looking to do?  What version of Tapestry are you using?
If you're looking to automatically inject a HiveMind service into all
of your pages/components, you can either use tapestry-autowire (tap
4.0) or upgrade to tap 4.1 which has tapestry-autowire built in.
Using tapestry-autowire, it's as simple as declaring an abstract
getter of the same type as one of your services in your HM registry
(provided there is exactly one service point which supports that
service interface):

public abstract MyService getMyService();

You can declare that in your MyAbstractPage class (or whatever you
want to call it) and all subclasses will inherit the property and
it'll be injected automatically.  Hope that helps.

Also , if Class X is empty do I need to create one in the first place ( am

 Hi Kevin,

This exception is "thrown if an Authentication object does not hold a

Keep in mind, though, that the tutorial above uses spring-style

Apparently, one could achieve the same result using tapestry-acegi and

Hi,

I'm having some difficulty using tapestry-acegi. I can secure a page fine,
but I can't figure out how to allow a user to auth.
Unfortunately, my experience with Acegi in general is practically
non-existent, so I may just be doing something dumb there.

I have a page marked @Secured("ROLE_USER"), but when I access it, all I get
is org.acegisecurity.AccessDeniedException.

My HiveMind registry contains the following:











with the UserDetailsService implementation basically being a no-op.
I've set a break point in the service and it never gets executed.

I am using both tapestry-acegi and hivemind-acegi-dao, for what it's worth.
Any help would be much appreciated.

Great, I got it going.

I read the documentation, had no idea what it was saying. Dug through the 
source code, got completely confused... then went back to the documentation, 
and then it made sense.. I just did a 3 line block element at the top of my 
HTML page, bam, it works! And they're very simple, for reference :



  



  




Thanks for the help both of you!

Thanks!

I'm still digging, it's a little confusing since it's split up as a JWC for 
LocaleSelection.. trying to piece everything together. I'd rather not split 
mine into a JWC file.

Yup, you only need to override the column(s) that need the custom
rendering. All others will be rendered as they are currently.

Yeah, I've seen that before.  I was able to work around it because it

Re: ServletContextListener equivalent in Tapestry

No, it should be set up by just implementing the method/interface on
your implementation class.  I wonder if the Tapestry code isn't
calling shutdown method on the registry.

I created a class and had it implement

However, when I redeploy my app, I don't see any

Re: ServletContextListener equivalent in Tapestry

Have your implementation class implement
org.apache.hivemind.events.RegistryShutdownListener interface and it
will automatically be registered for the events by HiveMind (as long
as you're not using the threaded service model).

Re: tapestry-acegi and tapestry 4.1

I haven't tried it, but it should work as far as I know.  You can
override the dependency in your own pom file

Re: hook into T4's page creation process

[James Carman]

The tapestry-acegi library does exactly this.  When it sees an Acegi
@Secured annotation on a class/method, it uses a worker to enhance the
class.  So, you can either use what I've already created or refer to
the source to see how to do what you want.  If you have any questions
about the code, don't hesitate to ask.  Hope that helps.

On 12/22/06, RonPiterman <[EMAIL PROTECTED]> wrote:

yes, workers are part of 4.0.2 - and the code is very clear, and one can
learn alot from it - howard has a *very* nice programming style, so its
worth taking a look.

I would look at the wiki, but I don't know if there are any
tutorials/docu around for this. It is quite advanced staff, but its not
that hard.

Cheers,
Ron

Re: T-Acegi: An AuthenticationManager is required

[James Carman]

  No, I'm not using tapestry-spring.


Well, HiveMind needs to know how to find the Spring objects.  So, just
drop tapestry-spring.jar into your WEB-INF/lib dir and see if that
fixes it (as long as your spring config file is named/located
appropriately).



What is the alternative way to configure acegi?


You use HiveMind to instantiate/configure your acegi objects.

  No, I'm not using tapestry-spring. It turns out that I got it to work
correctly using only spring's ContextLoaderListener approach. And as you may
have guessed, it doesn't work when dropping tapestry-acegi into the
classpath. The exception I get is the same, "An AuthenticationManager is
required" (please see my initial post).

> I didn't use Spring to set up my stuff...
  What is the alternative way to configure acegi? Does it offer the same
fine-grained control as spring's config xml?

Thanks for your time!

A qouple of questions:
Do you use JdbcDaoImpl or InMemoryDaoImpl?
Did you set up tapestry-acegi exactly as it described on the wiki

Me, and others reading this archive, will appreciate your help.

Re: Proper way to get ApplicationStateManager?

And, the coolest thing is that this sort of thing *can* be inherited
without using annotations (by putting it in a common superclass).
Otherwise, you have to use XML in your spec files to inject stuff into
all of your subclasses.

Re: Proper way to get ApplicationStateManager?

[James Carman]

What version of Tapestry are you using?  4.1?  If so, then it can
autowire stuff for you out of the HiveMind registry.  Just declare an
abstract getter that returns an ApplicationStateManager.  If you're on
4.0, you can download the tapestry-autowire source and build it (via
SVN http://svn.javaforge.com/svn/tapestry/tapestry-autowire/trunk/,
username/password anonymous/anon).  Just drop it into your classpath
and it will do the same thing as 4.1.

The tapestry-acegi library works (we use it at work currently and it's

Thanks James, but ...

I understand that I could not use StateFull Bean with Hivemind.
But how to use StateFull Bean from a Tapestry page ?
Is something like this possible :
ApplicationContext.getBean("TheStateFullOne");

I think the Application Server has to create the SateFullBean, but I've
no idea on how it can make the link between the AppServer's session and
Tapestry's session...

I'm a lost a little

Re: Hivemind and EJB access

[James Carman]

Well, I was answering the question of whether HiveMind's
EJBProxyFactory supports stateful session beans and it does not (the
reason is that the create method requires params).  If you want to use
a stateless session bean, then check EJBProxyFactory's documentation
on how to set it up in your hivemodule.xml file.  Basically, you use
EJBProxyFactory rather than BuilderFactory to construct your
implementation object.

Hello James,
Thank you for your response, but I'm afraid to do not understand it ;-(

Perhaps I have to reformulate my question :

When Tapestry runs in an Application Server (Glassfish,JBoss), how to
access EJB (Stateless and Statefull) from a Tapestry page ??

No, because typically with SFSBs, you have to pass in a paramter to
the create method and there's no way to set up the proxy to do that
for you automatically.  With SLSBs, there is no parameter to the
create method.

Re: @Secured from tapestry-acegi

[James Carman]

If you want to use a DAO-based (where you get auth information from a
db or something) authentication manager, you can drop in the
hivemind-acegi-dao.jar file into your classpath.  Then, you have to
provide an implementation for the
hivemind.acegi.dao.UserDetailsService service point:


 
   
 


There are some pre-defined implementations of UserDetailsService, but
to get the idea working you can provide a dummy implementation just to
make sure everything is pieced together correctly.

Re: @Secured from tapestry-acegi

[James Carman]

Ahh yes.  You do need to tell Acegi how you want to authenticate, so
you need to have an implementation defined for the
AuthenticationManager service point I define.

Hi James,

I've remove all stuff about acegi form my project.
Just added tapestry-acegi.jar in the Tomcat lib folder.

When starting Tomcat, the following exception is throwed. It claims "An

Re: @Secured from tapestry-acegi

[James Carman]

You don't need spring at all.  You would use your own hivemodule.xml.
I believe you can just drop in the jar and the BASIC HTTP
authentication will work.  There are customization points you can use
(like the name of your "realm" and stuff), but it should work "out of
the box."

Thanks a lot. I'm a beginner ...

Are directives in the hivemodule.xml from tapestry-acegi.jar are
sufficients, or we need to put some more directives in web.xml or spring
's applicationContext-security.xml ?

Re: Tapernate Access multiple database

[James Carman]

The majority of applications use one database, so Tapernate (actually
hivemind-hibernate3, which Tapernate is built upon) doesn't officially
support multiple databases.  Tapernate allows you to just drop jars
into your classpath, which makes it very simple to use.  It wouldn't
be so simple to set up if it had to try to keep track of multiple
databases.  I went for simplicity rather than trying to make it cover
a minority case.

On 11/16/06, Henry Chen <[EMAIL PROTECTED]> wrote:
> Thank you. Did you come up with any solution without Tapernate?

This is relatively simple if you aren't using a framework that
explicitly prevents it.  I use swing + hibernate to provide all the
layers to my app underneath the web layer and it is trivial to provide
access to multiple databases.  I can define multiple data sources in
my application context and then provide dao beans which use the
appropriate data sources as well as service objects which utilize
those daos.  My web layer isn't even aware of the location of data.
It just calls a method in the service layer, which may use DAOs from
multiple databases to accomplish the necessary work.  And with
spring's nice declarative transactions, it is easy, within the
confines of a JTA transaction in a J2EE container, to have a single
transaction span db access to multiple databases, which is really
convenient.

In my app, I have a situation where my entire domain model is provided
via hibernate to a single domain db, but the huge volume of data that
I need to provide access to for reporting is in 2 separate data
warehouses.  The domain entities are all accessed via DAO's using
spring's built in hibernate dao support classes, and I use pure JDBC
to access the 2 separate data warehouses.  So I have about 25 DAOs
using the hibernate data source (one for each entity), and one dao
using one jdbc connection to the first warehouse and 3 separate DAOs
using JDBC connections to the second warehouse.  I have service
objects which need to pass hibernate entities to the warehouse daos so
that they can construct the correct SQL statements for building
reports, so many of my service objects receive a reference to several
hibernate DAOs as well as at least one jdbc dao.  It works like a
charm.  All transactions are declared on service object methods, so
transactions automatically encapsulate access to every database used
by the service method, and my daos don't need to know a thing about
transactions.

Honestly, I can't imagine a system of this complexity having a simpler
interface since everything is done declaratively within the spring
application context.  There's not a single line of code devoted to
dealing with multiple databases.

Re: How to share hivemind registry between HiveMindFilter an ApplicationServlet?

[James Carman]

They didn't use our filter because they load a whole bunch of
different hivemodule files from non-standard locations.

On 11/16/06, Jean-Francois Poilpret <[EMAIL PROTECTED]> wrote:

Hi Nick,

Although I don't know much about Tapestry way to create the Registry and
give access to it, what you might possibly do with hiveremoting.caucho is to
subclass net.sourceforge.hiveremoting.caucho. CauchoRemotingServlet and
override its getRegistry method to whatever is suitable with Tapestry.

As far as I understand, it seems that in Tapestry, the Registry is created
by the servlet (ApplicationServlet), what would be interesting to find out
is when it is created (is it at init, or at first request?). If at init,
then find a way to access the Registry in a static way (if available), you
might also need to subclass Tapestry's ApplicationServlet to make its
Registry accessible.

But you are right: it looks strange that tapestry 4 does not use "HiveMind's
way" to create the Registry, ie through the HiveMindFilter.

Hope this helps

Subject: How to share hivemind registry between HiveMindFilter an
ApplicationServlet?


Hi,

I've found recently that very simple usecase for hivemind + tapestry is
lacking of any docs. Here it goes
1. I have tapestry application rooted by ApplicationServlet
2. In the same web application I want my services to be accessed via remote
api. Hence I've downloaded hivetranse (hiveremoting package) + hessian as
adhoc solution.

The problem is that hiveremoting depends on HiveMindeFilter to create
hivemind registry while tapestry (for nonundestandable reason) does things
by their own. Hence I'm having two copy of registries containig duplicate
instances of all of my services.

Is there any way to share the registry? I've read in the docs that tapestry4
has perfect integration with hivemind (compared to tapestry3), but
unfortunatelly documentation does not go beyond this statement. :(

It would be really strange if this is impossible, as tapestry is able to
share spring registry whith no effort at all..

Re: object injection and class cast

[James Carman]

The object you get is actually a proxy to the actual service
implementation.  The dynamic proxy only knows that it needs to support
the javax.servlet.Filter interface, so that's all it supports.  You
can't downcast it to the implementation class.  What you can do is
come up with your own service interface which extends
javax.servlet.Filter and your implementation class can implement that.
You'd have to use that interface to "talk to" your service object.

p.s. Alternatively, there is such a thing as bean services (the
service interface is the bean class), but I don't suggest using them.
It's better to front your services with an interface (which is what we
have to fabricate at runtime via Javassist to support bean services).

Re: tapestry-acegi questions

[James Carman]

You could use a callback somehow to do that, I would think.  But, you
would probably have to implement the auto-redirect-to-login-page logic
yourself, so that you could save the callback into the session or set
it on the login page as a property or something.

I came around to the same thing after looking at the Acegi basic auth
code. I'm doing something like this.

@InjectObject("service:hivemind.acegi.AuthenticationManager")
public abstract AuthenticationManager getAuthenticationManager();

public void doLogin()
{
  UsernamePasswordAuthenticationToken authRequest = new
UsernamePasswordAuthenticationToken( getEmail(), getPassword() );
  Authentication authResult;

  try {
authResult = getAuthenticationMananger().authenticate( authRequest );
  } catch( AuthenticationException failed ) {
SecurityContextHolder.getContext().setAuthentication( null );
return;
  }

  SecurityContextHolder.getContext().setAuthentication( authResult );
}

The only think I have left is to figure out how to redirect back to
the original page where the user was at the time the authentication
was wanted. Is that saved somewhere or do I need to find out that for
my self?

Re: Question regarding Block/RenderBlock

[James Carman]

You can create a page that has a bunch of @Blocks in it and you can
use those blocks in other pages.  We do that in Trails and it works
quite nicely.  Check out the org.apache.tapestry.util.ComponentAddress
class.  It allows you to "look up" components on other pages.  So, you
can use it this way...

public Block getReusableBlockFromAnotherPage()
{
 ComponentAddress addr = new ComponentAddress(
"MyReusableBlocksPage", "myReusableBlock" );
 return ( Block )addr.findComponent(getRequestCycle());
}

In your page, you'd do this:



This is off the top of my head, so the syntax might not be exactly
correct, but you get the general idea I hope.  Hope that helps!

That issue just says HM isn't JDK1.3 compliant.  But, if you're not
running a 1.3 JDK, then all should be okay.

I am using WSAD v5.1.1 with the following configurations:

java version "1.4.2_05"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_05-b04)
Java HotSpot(TM) Client VM (build 1.4.2_05-b04, mixed mode)

In a separate project I was able to run

StringBuffer a = new StringBuffer("1");
StringBuffer b = new StringBuffer("2");
a.append( b );
So the problem seems to be something related to Tapestry not WSAD.

The following link indicates that the problem may be something related
to HiveMind.

What version of WSAD?  There's an "Interim Fix 008 for WebSphere
Application Developer v5.1.2" that has something in the release notes
about "This fixes a problem where the
StringBuffer.append(StringBuffer) method is not found on JDK 1.3."
