Question

My application failed to start with the below error on WebSphere Application Server 8.5.5.10 which was working on 8.5.5.5

1. The application failes to start after deployment
2. The application failes to start when JVM starts
3. The same application is getting started manually from console.

4. When i put reflections-0.9.10.jar in shared library i am getting Failed to load webapp

   Caused by: com.ibm.ws.webcontainer.exception.WebAppNotLoadedException: Failed to load webapp: null

5.The application started when i move all the third party jars to shared libraries.

Answer 1

The SystemOut.log file for the application server will indicate which version of the Java (JVM) is in-use. Verify whether the version of the class files in reflections-0.9.10.jar is greater than the version of the server JVM. The error you posted will occur whenever this condition is true.
