weblogic/utils/NestedException

Working with Weblogic 8.1, it’s fine just to put jar of weblogic-8.1.jar into your classpath, your client application will find weblogic server easily but with Weblogic 9+ (in my case, Weblogic 10.3), it’s not the case if you don’t know.

You may get similar errors as:

 

1 2 3 4 5

java.lang.NoClassDefFoundError: weblogic/utils/NestedException or java.lang.NoClassDefFoundError: weblogic/descriptor/DescriptorBean or java.lang.NoClassDefFoundError: weblogic/utils/classloaders/GenericClassLoader

So you will try to drop following jars:

• weblogic-10.3.0.0.jar
• webserviceclient.jar
• wlclient.jar
• wlfullclient.jar
• wljmsclient.jar
• wls-api.jar or
• wseeclient.jar
• etc

But you will find it more than 2 days and still got most of NoClassDefFoundError as my cases, I almost went crazy with all these but finally found the solution, it’s an easy way to group all needed client jar into one jar file: wlfullclient.jar via command:

 

1	WL_HOME/server/lib>java -jar ../../../modules/com.bea.core.jarbuilder_1.2.0.0.jar

You will find it in weblogic server lib folder (WL_HOME/server/lib/wlfullclient.jar)

Add it into your client application classpath: ./wlfullclient.jar and drop the file into your client app library.

Everything will be Ok.

Do not doubt as myself, Good luck!
