RE: [JBoss-user] How to look up one bean in one jar from another bean in another jar cleanly

[Allen Fogleson]

Im assuming since it says "will be the default" that there will be other options to use current deployment schemes. Nothing wrong with that at all as I see it. So I assume the per-jar/per-container/global you speak of will be supported in whole or part.   Al -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Lachezar Dobrev Sent: Thursday, June 07, 2001 8:33 AM To: [EMAIL PROTECTED] Subject: Re: [JBoss-user] How to look up one bean in one jar from another bean in another jar cleanly    HELL NO!    This is not so good, as it looks like in first glimpse.    This means, that you can NOT use different class implementations is different EARs... That is totaly undesirable, although it may make things easier for a project breaking into multiple EARs.    That is why IAS/BAS has a setting for the classloader. It can be either PER-JAR, either PER-CONTAINER either GLOBAL. Let this be the developer's issue. OK?      Lachezar. Another opportunity is the org.jboss.deployment.scope.J2eeGlobalScopeDeployer (csv source only, will be default for 3.0) that allows separate ear�s to share classes.   Just to advertise ;-) CGJ -----Urspr�ngliche Nachricht----- Von: Lachezar Dobrev [mailto:[EMAIL PROTECTED]] Gesendet: Donnerstag, 7.

When packaging jar2 you have to put the home and remote interface of bean1 in it. Other way is to package ALL home and remote interfaces into a jar and put it in lib/ext. I prefer second.      May the shade of the tree strengthen you.    Lachezar. Hi, I have to deploy 2 jar files in JBoss2.1 for my EJb based application - jar1 containing bean1 and jar2 containing bean2   In bean 2  I lookup bean1 using ctx.lookup("java:comp/env/bean1").   Using the jar tool ejx.jar i edit the xml's of jar2 and map the ejb-reference "bean1"  to bean1's JNDI name   I place both jars in the deploy directory and start the jboss server   When trying to invoke bean 2 methods from my application client on the Server side i get the Exception :-          java.lang.NoClassDefFoundError:  bean1   So i placed jar1 containing bean1  in the lib/ext   directory.   This solved my problem and  my application works properly.   But the side-effect is  that since i have   jar1 containing bean1 files in lib/ext, whenever i run the jar tool ejx.jar and whatever jar i open any jar for editing it always opens the xml's of jar1. (My feeling is the META-INF/ejb-jar.xml  is loaded using ClassLoader.getResourceAsStream and since lib/ext is the first thing in the CLASSPATH that xml will always be the one which is read).     So I need to remove the jar1  from  lib/ext when i want to run ejx.jar  but i need to put it back when i want to run the jboss server.   I can try to have another copy of jar1 (minus the xml files) in lib/ext . But it is a big headache with multiple copies of  jars with just the xml's  missing.   I reason there must be a better solution than this and moreover it is a big nightmare explaining installation instructions to our clients which has to take care of these issues.   What is the cleanest way  to look up one bean in one jar from another bean in another jar and where should the classpath be set?    I have looked at the archives and could not find a satisfactory solution.     Thanks in advance, Munesh Gupta
