OC4J's servlet and Weblogic's EJB problem

Question

Hi all,
Is it possible to look up the weblogic.jndi.WLInitialContextFactory from servlet deployed into OC4J ?
I copied weblogic.jar and MyEJB.jar to \j2ee\home\lib and re-started OC4J.
When the servlet runs for the first time, I can see the following displayed:
java.lang.InternalError: error initializing kernel
     at weblogic.kernel.Kernel.ensureInitialized(Kernel.java:86)
     at weblogic.jndi.WLInitialContextFactoryDelegate.<init>(WLInitialContextFactoryDelegate.java:166)
     at java.lang.Class.newInstance0(Native Method)
     at java.lang.Class.newInstance(Unknown Source)
     at weblogic.jndi.WLInitialContextFactory.getInitialContext(WLInitialContextFactory.java:147)
     at javax.naming.spi.NamingManager.getInitialContext(Unknown Source)

     at javax.naming.InitialContext.init(Unknown Source)

     at myServlet.doGet(myServlet.java:41)
     at javax.servlet.http.HttpServlet.service(HttpServlet.java:195)
     at javax.servlet.http.HttpServlet.service(HttpServlet.java:309)
     at javax.servlet.http.HttpServlet.service(HttpServlet.java:336)

     at com.evermind[Oracle9iAS (9.0.2.0.0) Containers for J2EE].util.ThreadPoolThread.run(ThreadPoolThread.java:64)
Next time servlet's response is as follows:

weblogic.common.internal.VersioningError: No WebLogic packages defined in CLASSPATH
     at weblogic.common.internal.VersionInfo.<init>(VersionInfo.java:39)

The 41th line of myServlet.java is as follows:
Context jndiContext = new InitialContext(env);
OC4J and Weblogic ara installed on the different computers.
The same myServlet.class deployed into other Weblogic (installed on the same computer as OC4J) works correctly.
What I did miss ?

Answer 1

yes....if you are using only hibernate3.jar and no other jars from hibernate then you need this jars for hibernate to work.
antlr-2.7.6rc1.jar
asm.jar
asm-attrs.jar
cglib-2.1.3.jar
commons-collections-2.1.1.jar
commons-logging-1.0.4.jar
dom4j-1.6.1.jar
ehcache-1.1.jar
hibernate3.jar
jaas.jar
jaxen-1.1-beta-7.jar
jdbc2_0-stdext.jar
jta.jar
log4j-1.2.11.jar
ojdbc14.jar
xerces-2.6.2.jar
xml-apis.jar
if you are missing any of those, hibernate won't work.
You can check in MyEclipse which jars hibernate needs to run successfully. Just go under Window/Preferences, and there go under MyEclipse/Project Capabilities/Hibernate and select tab Hibernate 3.1 and under Library modules select Hibernate 3.1 Core Libraries, and you will see which jars hibernate need. ;)
