I've been struggling with this error whenever I start my local server.
What I have done:
1. removing and adding project which didn't help at all
2. updating my JAVA_HOME
FYI, I'm working with jdk 1.7 and Websphere 8.5.5.8
Error below is the one causing the deployment goes boink
[ERROR] CWWKZ0002E: An exception occurred while starting the application APP_war_exploded. The exception message was: com.ibm.ws.container.service.state.StateChangeException: org.jboss.weld.exceptions.DeploymentException: incompatible InnerClasses attribute between "com.ibm.ws.beanvalidation.v11.cdi.internal.ValidationExtension$AnnotatedTypeFilter" and "com.ibm.ws.beanvalidation.v11.cdi.internal.ValidationExtension"
Does anyone know how to fix this?
Based on Andy's answer here, it looks like you need to update your SDK to the latest version of 1.7, like 7.1.3 or greater.
