NoClassdefFound Problem using EJB as web service client

Question

Hello there, I am trying to use a MDB as a web service client. The architecture,
briefly is in the form of a java program communicating with a MDB via JMS, the
MDB gets the data from some external server via SOAP. I am using JBuilder to generate
the client side classes choosing the Axis framework. When my MDB is trying to
bind using locator.getPort() it throws an error as follows:
java.lang.NoClassDefFoundError: org.apache.axis.client.AxisClient. java.lang.NoClassDefFoundError:
org.apache.axis.client.AxisClient at org.apache.axis.client.Service.getAxisClient()Lorg.apache.axis.client
AxisClient;(Service.java:143) at org.apache.axis.client.Service.<init>()V(Service.java:152)
Note that it works fine if I use the web services client as a standalone java
program(no weblogic ). I tried putting the Axis.jar file as well as the relevant
files from this jar file(JBuilder's feature) in the EJB module that is deployed,
of no avail. Following is the classloader printed from the EJB's onMessage method
if needed for better understanding
weblogic.utils.classloaders.GenericClassLoader@afdd3a finder: weblogic.utils.cla
ssloaders.MultiClassFinder@20d7479 annotation: SecurityEJBModule@
Any help will be appreciated

Slava, I did exactly that and it worked! I wish I had seen your reply before.

if needed for better understandingYou need to package all Axis jars and dependancoes into the EAR and
refer tham
in your ejb-jar MANIFEST.MF. If you are running weblogic 8.1, you may
just put them
into APP-INF/lib. Than you won't need to modify manifest.
Hope this helps.
