Exception in thread "Main Thread" java.lang.NoClassDefFoundError: weblogic/

Question

hi,
I am getting error message when i run HttpClient in my java class. Will the HttpClient will work in weblogic.
HttpClient httpclient = new HttpClient();
I added "commons-httpclient-3.1.jar" in the class path also.
Exception in thread "Main Thread" java.lang.NoClassDefFoundError: weblogic/kernel/KernelLogManager
     at weblogic.logging.commons.LogImpl.<init>(LogImpl.java:14)
     at weblogic.logging.commons.LogFactoryImpl.getInstance(LogFactoryImpl.java:21)
     at weblogic.logging.commons.LogFactoryImpl.getInstance(LogFactoryImpl.java:18)
     at org.apache.commons.httpclient.HttpClient.<clinit>(HttpClient.java:66)
Thanks
Manu

Again you need to make a difference between what runs within the weblogic container to what runs in a vanilla JVM. Understanding this is crucial to your problem.
1. web service -> client -> another web service
The webservice will always run within the weblogic container and you should never get the ClassnotFound because weblogic.jar is always available there. Any subsequent clients loaded into the same JVM will presumably be in the same classloader and wont have problems either
2. client -> web service;
If you are using a standalone client in a JVM you shouldnt have any dependency on weblogic and commons-httpclient will work just fine as would commons-logging. However if you include some weblogic jars in the classpath, when you launch the client JVM you would need to include the jars mentioned in the other post because they reference other weblogic classes. But this isn't necessary if you just clean up your classpath to only have the jars you need.
