RE: [JBoss-user] Http Session Clustering, JGStore debugging
I have reported a problem with JGstore a couple of weeks ago that is still unanswered. I would like to get my hands dirty and debug it myself. But I would like to get some tips on the way to do it. Is there a way I can use a kind of debugger to find out whats wrong? Should I rely only at increasing log level? I have no ideia if one can run jboss on top of debugguer (is there a java debuger, something similar to gdb but in java world?) Enable JPDA on your VM (look thru run.bat/run.sh to see how to enable it) Certain IDEs will let you connect to the port that JPDA is listening on and debug. Sorry, forgot to mention a few: Forte, Eclipse, never tried but I am sure they alos do JBuilder, JDeveloper etc. I am not sure of gdb kind of debugger ... I think there is jdb in the bin directory of your JSDK. Alex. --- This SF.net email is sponsored by: ValueWeb: Dedicated Hosting for just $79/mo with 500 GB of bandwidth!

RE: [JBoss-user] Re: Hibernate or ejb
I do not mean to anger the public here by being off-topic, just could not keep my mouth shut. The first thing we came across is the problem of lazy instantiation. Let's say you have object A that has a relation to obect B. But you only want to load A and B later when it is used. Hibernate cannot handle this (this is an open bug but maybe fixed in the new 2.0 beta). We have found a way around this but it is not very nice. Hmm, it works for me. But then again I work with 2.0. It actually pretty neat how hibernate does things in respect of lazy collections. You only initialize them when you need them, and I think Gavin is in process of adding a method call called isInitialized () for a lazy collection. You can do even more you can disconnect your session and initialize lazy collection when you need it. Then of course you need to reconnect with the same Session. The problem with collections is that it is fairly difficult to configure them and there just a gazillion options and way to do it. You just need to experiment. Another thing is definitely the caching in hibernate. You never know when hibernate actually saves the data to your DB. I think you are worng here too. First of all if you use a persistence tool then you should not worry about when it saves the stuff to the DB. Second of all if you do not want Hibernate to save your stuff call on session session.setFlushMode (FlushMode.NEVER) will let you control when you want to do the actual flushing. Then of course you need to call session.flush () yourself. I usually do not trust my saves to anyone :-) so the manual flush works for me. The last thing that kept us busy was the fact the (assume the schema as above) when you save B then A does not get updated. This means you have to take care of updating A manually when you change B. It took some time to figure this one out. Not sure of this point but cascade=save-update or cascade=all setting in the descriptor work just fine. What is true is that there is a problem when updating the children. If you changed the child and want to somehow update the parent at the same time you will need to do some Interceptor coding but this is doable. For more see the hibernate forum. So, I have to go back to my project and get some more experience with hibernate. looks like you are right :-) Anyway hibernate is very usefull, just do not jump to the conclusions before giving it enough time.

RE: [JBoss-user] EntityBean findAll() method
I think the reason (or maybe just one of them) for the
query sent is the assumption that you might not read all
the records all the time but only a few at a time, you
might even stop reading them in the middle of your
processing:
Collection c = yourBeanHome.findAll ();
// Suppose this returns 2000 records after executing
// SQL with no where (id = ?) or (id = ?)
Iterator i = c.iterator ();
int counter = 0;
while (i.hasNext ()) {
YourBean yb = (YourBean) i.next ();
if (counter 5) { break; }
counter ++;
}
So in the scenario above you actually retireved only
five records. If you were not to have that strange
where statement in your SQL, you would waste creation
of exactly 1995 records. But since you did have it
you only wasted the retrieval of your ids and
page-size - 5 records. JBoss lets you manage this
situation thru that where and the settings in the
jbosscmp-jdbc.xml

JBoss sends in the fist call all id's linked by 'or' operator. in the secodn there are n-1 id's and so long. You look at it as if you are the only one who has a problem to solve. JBoss looks at the worst case scenario and the best case scenario and try to find a solution that is optimal. That might not be neccesarily an optimal solution in each individual case. --- This SF.net email is sponsored by: Scholarships for Techies! Can't afford IT training?

I didn`t post the dtds because the logs is pretty obvious. As you can
see there is no jboss*.xml so the mapping should be straight forward -
however the seeking doesn`t work.
Where`s the glitch?

RE: Re[3]: [JBoss-user] help with bounding entity bean
Btw, how can I use the general context search, i.e. java:/comp/env/... use ejb-ref or ejb-local-ref in your web.xml --- This SF.net email is sponsored by: Scholarships for Techies!

RE: Re[5]: [JBoss-user] help with bounding entity bean
Just to see that I am sure(please correct me and ofc any explanation
is appreciated).
the ejb-ref and ejb-local-ref work also with local/HandlerBean
meaning I still a re-map from local/HandlerBean to something else.
The ejb-ref and friends as far as I know is used together with the
session bean. In my case I could access the bean without using the
ejb-ref (I found it`s name from the jmx-console). (can anyone shed
some light in this area?).
Okay, each component [application, web context, ejb, ] you deply
will have its own Context. It will be located at java:/comp/env.
Now if you are looking for something that is bound to java:/comp/env
from with a servlet you have to put it there. You would put it there
thru ejb-ref in your web.xml
If you used java:/comp/env from within an EJB then you would need
references in the ejb-jar.xml
That is all true about local context. JBoss however has a global context.
Where it binds your objects. I am not sure exactly what convention is
when you do not provide those three optional xmls that I was talking
about in my earlier post, but those are basically needed to provide
connections.
So jboss.xml will bind your ejbs into the global context so that other
components [apps] can reference it (in their local java:/comp/env;
jbossweb.xml will do similar job for your web app.
Okay just to give you some example, suppose we have a bean Facade:
ejb-jar.xml
session
description![CDATA[Facade Bean]]/description
ejb-nameFacade/ejb-name
homeedu.columbia.law.tas.ejb.FacadeHome/home
remoteedu.columbia.law.tas.ejb.Facade/remote
ejb-classedu.columbia.law.tas.ejb.FacadeEJB/ejb-class
session-typeStateful/session-type
transaction-typeContainer/transaction-type
/session
jboss.xml
session
ejb-nameFacade/ejb-name
!-- note this is your global name for FacadeHome
watch it referenced in jbossweb.xml --
jndi-nameejb/tas/FacadeHome/jndi-name
/session
web.xml
!-- this is the declaration that will bind FacadeHome into the
local context of your web application so that you can do
InitialContext initialContext = new InitialContext();
try {
java.lang.Object objRef =
initialContext.lookup(java:/comp/env/ejb/Facade);
return (edu.columbia.law.tas.ejb.FacadeHome)
PortableRemoteObject.narrow(
objRef,
edu.columbia.law.tas.ejb.FacadeHome.class);
} finally {
initialContext.close();
}
--
ejb-ref
ejb-ref-nameejb/Facade/ejb-ref-name
ejb-ref-typeEntity/ejb-ref-type
homeedu.columbia.law.tas.ejb.FacadeHome/home
remoteedu.columbia.law.tas.ejb.Facade/remote
ejb-linkFacade/ejb-link
/ejb-ref
jbossweb.xml
!-- finally this is where you connect your ejb/Facade to
the global home --
ejb-ref
ejb-ref-nameejb/Facade/ejb-ref-name !-- local name fo it --
jndi-nameejb/tas/FacadeHome/jndi-name !-- global context look at
jboss.xml --
/ejb-ref
That is about it. The only thing that I can not find in jmx-console
is how do I see the env context of my web context it has to have
one, but it might be Jetty hidden. So I have not found a way to browse it.
Alex.

RE: [JBoss-user] Recursive Tables (Trees) and CMP in JBoss
my problem is to represent this structure in cmp ejb. any ideas? The only pecky part of your schema is that self referenced EJB (tree). As to others relations they are straight forward, just relate :-). I am attaching zipped sample code that has the following relation coded: +---+ | participant | +---+ * | idinteger pk | --+ | name varchar || | manager integer | ---+ | ... | 1 +---+ it is xdocleted code (and will not compile as is, since it references couple of other classes that you do not have, and has omissions from the original) but see the descriptors that it generates (I only have the relevant parts in there). The table created is the one shown above or very close to that. is it possible to access these objects over SOAP webservices? do not know. recursiveEJB.zip Description: Zip compressed data

RE: [JBoss-user] deploying to JBoss from Eclipse
I found the JBoss-IDE plugin for Eclipse and installed that. It starts and stops the server, other than that it doesn't do much that the EASIE plugin from Genuitec doesn't do. It also has xdoclet code assist. Which is pretty nifty stuff. 1) Make the eclipse project within the JBoss folder and set the output path to be inside the server/deploy dir Well if you use ant to build your project (which you probably should since xdoclet assist feature only makes sense if you use ant) then just add another task say jboss_deploy and copy your jars, ear, wars to the server deploy. I think the problem is not in making the JBoss run within Eclipse. I just do not see any need for it. Run it separately and remote debug your stuff if you must. What would be really cool if there where some tools to create an EJB, configure your deploymnet descriptors (ejb-jar, jboss, jboss-cmp etc.). I mean XDoclet is nice but it is so entrenched in your code that you really have to know what you are looking to find it. And even then it is easy to miss it. Some console that shows the structure of your running JBoss instance or cluster (jndi tree, ejbs deployed, topics, queues, resource adapters, datasources etc.) would be nice. Also while I type my code I would really like to have XDoclet to create files while I type, otherwise I can not use code assist in eclipse for the classes that will only be generated after the build. Oh and by the way you can take a look at Lomboz plugin at www.objectlearn.com. Looks cool, I just was not able to make it work with JB 3.2 :-( Alex. --- This SF.NET email is sponsored by: SourceForge Enterprise Edition + IBM + LinuxWorld = Something 2 See! http://www.vasoftware.com ___ JBoss-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-user

It might be that jboss can't find where the MBeans are. So if you set jboss.home to the parent directory of the run.jar file system property before you make a call it might help. Alex. Has anyone tried starting JBOss from within another Java application by calling org.jboss.Main.main(args) ?

You can also script it. like the following:

response.setHeader (Pragma, no-cahce);

response.setHeader (Cache-Control, no-cache);
}

That's a browser issue. If you're on IE or Netscape, you can change the
settings to always compare documents to cached versions. This should fix
the problem. Also, if you're on Netscape, you can just hold down
shift and
click the reload button. This will force a non-cached reload.
