[JBoss-user] Activation Failure after beanLocal.remove()
Okay for those of you interested in the work around to my problem (listed below). I think the servlet init method only gets called once no matter how many instances of the servlet exist. Hence, when you remove the ejb there is nothin re-creating it. Solution: before calling the bean make sure it is not equal to null, if it is re-create it. Also when you remove() it, make sure you set it to null. That's all. If anyone disagrees with my logic please let me know. Ricardo Hello I have been trying to look for info on this problem and I have notfound anything useful.Let me describe my problem.I have an applet that accesses a servlet that in turn communicates with anEJB.in the Applet.destroy() I send a request to my servlet called "endSession"this gets handled by my servletwich in turn calls the local reference of my beans remove method that isbeanLocal.remove();This appears to end the session just fine, but when I try and make use ofthat bean again it gives me the following error:16:03:11,181 ERROR [AbstractInstanceCache] Activation failurejavax.ejb.EJBException: Could not activate; CausedByException is:C:\Programme\jboss-3.0.1\server\default\db\sessions\Controller\1036594697323.ser (Das System kann die angegebene Datei nicht finden) atorg.jboss.ejb.plugins.StatefulSessionFilePersistenceManager.activateSession(StatefulSessionFilePersistenceManager.java:239) atorg.jboss.ejb.plugins.StatefulSessionInstanceCache.activate(StatefulSessionInstanceCache.java:83) atorg.jboss.ejb.plugins.AbstractInstanceCache.get(AbstractInstanceCache.java:177) atorg.jboss.ejb.plugins.StatefulSessionInstanceInterceptor.invoke(StatefulSessionInstanceInterceptor.java:212) atorg.jboss.ejb.plugins.AbstractTxInterceptor.invokeNext(AbstractTxInterceptor.java:107) atorg.jboss.ejb.plugins.TxInterceptorCMT.runWithTransactions(TxInterceptorCMT.java:178) atorg.jboss.ejb.plugins.TxInterceptorCMT.invoke(TxInterceptorCMT.java:60) atorg.jboss.ejb.plugins.LogInterceptor.invoke(LogInterceptor.java:203) atorg.jboss.ejb.StatefulSessionContainer.invoke(StatefulSessionContaineetc.I've read in some places that this has to do with the max-bean-age in theconfig file.As I understand it one you call this method there is a discrepancy betweenwhat was passivated and what the new ejb localobject.I don't really understand this problem as I am able to call the beanRemote.remove() method without getting the above error stack.So my question is how can I end the EJB session when the applet isdestroyed? and why can't I use the beanLocal.remove() method.Thancks,Ricardo

Re: [JBoss-user] JBossNetSubTask.class and jboss-net_xml.xdt
Okay just some dumb questions. I found the class you are using int he CVS of sourceforge.org, but how do I download that version of JBoss, or do I just download the JBossNetSubTask.class and then try and compile it. What do I do then, do jar it and drop it on the ant/lib? Can you give me some steps on how to go about doing this please.

Re: [JBoss-user] Simple Hello-World Webservice for 3.2?
I have not played too much with this example. I just got it to work for what I needed it. I used it as a reference on local interfaces. Hence I was happy to see a servlet acces an EJB through local interfaces. But, having had some experience with EJBs perhaps we can debug this together. Okay, generally there are several places where you can place your classes and I'll try and go through them all, starting with where I think it should go. There are 6 possible places that come to mind where you can put your libraries. 1.) create a lib directory in the *.EAR and re-place the manifest of the modules (*.WAR or *.WSR) with the following: --- MANIFEST.MF start --- copy below: Manifest-Version: 1.0 Class-Path: ./lib/. --- copy above MANIFEST.MF --- the . refers to the root of the ear and the lib/. refers to all files in that directory. I recommend placing all of your libraries here and keeping your modules light as this will make the classes accessible to all your modules. 2.) The second place to put it would be on the WEB-INF/lib directory of *.WAR if only your web module requires the lib. You should check this. This directory is the standar place to put your jars for the web module. 3.) Put them on the root of the web module. This will make them accessible to anyone on the net and also to your app. This is wher you would put *.jar s for applet code that needs to be downloaded by the users. 4. 5. 6) Put them in the lib directory of of either the all, default or minimal server folders of JBoss. This will make the classes in the *.jar available to all your deployed apps. NOTE: It is never a good idea to put your classes here as you make your code server dependent. You should distribute all of your libraries with your application, that way you can just drop them from one server to another. Another word of advice is to learn how to use ANT and Xdoclet, these two tools facilitate programming of EJBs. Okay, I hope this helps. - Original Message - From: Rupp,Heiko [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Wednesday, October 23, 2002 1:11 PM Subject: RE: [JBoss-user] Simple Hello-World Webservice for 3.2?

Re: [JBoss-user] log4j 1.2x required by an external client?
Hello Hans, I am using Jboss 3.0.1 I have made an example of a servlet that communicates with an EJB run before. The problem that you might be having is that JBoss and Tomcat are two stand alone applications. Therefore, Tomcat is unable to see the context of the deployed applications on JBoss (I am just guessing here). In my opinion you hav two options. 1.) Don't use tomcat. After all it's just web application container. USE JETTY. Which is lighter and perhaps faster (dunno). Jetty is packaged with JBoss so deployment is just as easy. Also, you can see the context of your deployed EJBs from this embeded web container (Jetty). Be sure to place a web.xml in the WEB-INF directory, even if you don't put anything on the web-app/ tag otherwise you won't be able to deploy your WAR in Jetty. with regards to any libraries that you might need, be sure to include them in the lib folder of JBoss. There are several lib folders, the one that has worked for me is: JBOSS_HOME\server\default\lib 2.) Use tomcat! So your preferred Web Application Container is Tomcat, you are used to it and you are happy with the way it performs, and you don't mind the space that it uses up on your hard drive (I am just being over synical). Then download one of the JBoss-Tomcat distributions. These are found in the same place where you found JBoss and you should be able to see the context of the deployed EJBs. I hope this helps.

Hi, I just updated from Jboss 3.0.2 to 3.0.3. when my Webapp client (using log4j-1.1.3) creates the InitialContext to connect to JBoss, it fails with 2002-10-02 14:43:10,226 451040 [Thread-21] DEBUG (services.ejb.EJBService) - JNDI test connection failed java.lang.NoClassDefFoundError: org/apache/log4j/Level This class is present in log4j_1.2x and up only! We use Jboss for handling EJB's only. Our System runs on a standalone Tomcat 3.3.1. The servlets (actually helper classes) connect via the standard JNDI lookup mechanism to JBoss. Any Ideas, why the use of jbossall-client.jar by our Webapp forces this Webapp to use Log4J at all, and especially a special version of it? It is not a big deal for us, because we have to update to log4j-1.26 anyway. It is just strange from an architectural point of view. (and please do not add log4j into the jbossall-client.jar. It is already overloader IHMO) I stopped trying to find out, which of the many client jar files are actually required to execute simple Session beans.
