Re: [JBoss-user] embedded tomcat 4 issue
I haven't found any Entity Bean tests in the test suite so I couldn't compare.

Re: [JBoss-user] embedded tomcat 4 issue
Thank you for your input. I'm making much progress in this area and most of my application works with tomcat locally now. I have got everything to work at this point except for one Entity Bean (CMP 2.0). I have other Entity Beans that work fine. So this is really tricky. I can lookup the bean and get the Home Interface from my servlet/jsp. Then, when I try to call findByPrimaryKey, I get a NullPointerException: java.rmi.ServerException: null; nested exception is: java.lang.NullPointerException 2002-04-17 11:03:33,118 ERROR [STDERR] java.lang.NullPointerException 2002-04-17 11:03:33,118 ERROR [STDERR] at org.jboss.ejb.EntityContainer$ContainerInterceptor.invokeHome(EntityContainer .java:1107) 2002-04-17 11:03:33,119 ERROR [STDERR] at org.jboss.ejb.plugins.AbstractInterceptor.invokeHome(AbstractInterceptor.java :73) 2002-04-17 11:03:33,119 ERROR [STDERR] at org.jboss.ejb.plugins.EntitySynchronizationInterceptor.invokeHome(EntitySynch ronizationInterceptor.java:230) 2002-04-17 11:03:33,119 ERROR [STDERR] at org.jboss.resource.connectionmanager.CachedConnectionInterceptor.invokeHome etc... This is funny because it only happens on this one bean. Other beans are configured the same way and work fine. Also this works when I use tomcat on a remote box (I just checked again to make sure) or in a separate JVM. I added some debug statements to org.jboss.ejb.EntityContainer.java I found that The map does contain an entry for the findByPrimaryKey method but when the homeMapping.get(mi.getMethod()) is called, it returns null. Is this a class Loading issue like there used to be? I wish I could submit a test cast but when I try a simple example it works fine. I have 10-15 beans deployed/a mix of Session/SLS/Entity. The problem occurs on this one bean every time without fail and independent of which jsp/servlet tries to use it. Everything works great when I run tomcat on a separate box. In the mean time, I'll keep playing and seeing if I can find something unique about this bean? Again, Thanks for any input. -Dennis On Wed, 2002-04-17 at 02:51, Scott M Stark wrote: I haven't found any Entity Bean tests in the test suite so I couldn't compare.

RE: [JBoss-user] embedded tomcat 4 issue
I agree, this is becomming a pain. I went back to the basics with my App. I did exactly what the jbosstest-web.ear does to deploy and lookup ejbs. After I made a couple modifications to my web.xml Most of my session beans started working fine. I started getting NullPointerExceptions (Below) in Entity Beans now?? I Can't understand why - they shouldn't be any different than session beans should they?. Note that everything works fine if I use tomcat on a remote box instead of deploying an ear to jboss/tomcat bundle. I haven't found any Entity Bean tests in the test suite so I couldn't compare. This problem may not have anything to do with Session/Entity and may just be a configuration issue with the beans - I don't know. I've tried placing the ejb-ref tag in the web.xml like the test does, I've tried placing an ejb-ref tag in jboss-web.xml instead like one user suggested below. I've tried not placing any ejb-ref tags anywhere and just looking up the JNDI name of the EJB. Each different situation seems to have some things that work and some things that break. Maybe someone could suggest the best way to do it that should work every time. Question I have: Assume InitialContext ctx = Assume correct xml config 1. Is there any big difference between: a. ctx.lookup (MyEJB ) without adding anything to the web.xml (like ejb-ref) b. ctx.lookup ( java:comp/env/ejb/MyEJB ); after adding ejb-ref...nameejb/MyEJB/name. to the web.xml 2. Because I am trying to get the app to run on both embedded and remote tomcat configs, I pass in a properties file to InitialContext when I create it. ie ctx = new InitialContext(props); That way I don't have to modify any tomcat scripts to get the right jnp properties and all. Does this make any difference to the embedded tomcat on jboss?

Re: [JBoss-user] embedded tomcat 4 issue
Hi, 2. Because I am trying to get the app to run on both embedded and remote tomcat configs, I pass in a properties file to InitialContext when I create it. ie ctx = new InitialContext(props); That way I don't have to modify any tomcat scripts to get the right jnp properties and all. You're better off using the new InitialContext() constructor with no params, and setting system properties through the jndi.properties file int he classpath. as far as the rest of things go, this is with jetty, but it might help: http://main.jboss.org/thread.jsp?forum=50thread=4046message=384447 cheers dim - Original Message - From: Dennis Muhlestein [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Wednesday, April 17, 2002 8:48 AM Subject: RE: [JBoss-user] embedded tomcat 4 issue ___ JBoss-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-user
