I found strange problem during porting from jBoss. Sometimes when we are starting the application we end up in white blank screen in admin console. Checking the logs I see this error:
[1/6/14 9:10:28:548 CET] 0000007e ServletWrappe E com.ibm.ws.webcontainer.servlet.ServletWrapper service SRVE0014E: Uncaught service() exception root cause action: com.ibm.websphere.servlet.error.ServletErrorReport: java.lang.NoClassDefFoundError: org.apache.commons.lang.StringUtils
My application is ear with on war in it, both(ear+war) contains in MANIFEST-MF file classpath entries commons-lang.jar. The ear file hold this referenced jar in its /lib folder. So I don't know why WAS has problem particullary with this library. I red some article where it is said, that WAS runtime libs already are using commons-lang library, but that should imply some version clash not a ClassDefFoundError, right?
Anybody ideas? Any help highly appreciated.
