I was working with gvNIX after installing jQuery and everything worked fine. But, when I installed the datatables web mvc datatables setup and the app was compiled, the web crashed and the server shown this error:
2015-05-25 12:47:34,583 [localhost-startStop-1] ERROR org.springframework.web.context.ContextLoader - Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in file [/home/vicente/Documentos/sts-bundle/pivotal-tc-server-developer-3.1.0.RELEASE/base-instance/wtpwebapps/FitTrainning_WebService/WEB-INF/classes/META-INF/spring/applicationContext.xml]: Invocation of init method failed; nested exception is java.lang.NoSuchMethodError: javax.persistence.Table.indexes()[Ljavax/persistence/Index;
Caused by: java.lang.NoSuchMethodError: javax.persistence.Table.indexes()[Ljavax/persistence/Index;
Are you deploying on a JBoss? There is a problem due JPA API version (JBoss includes 2.0 but gvNIX requires 2.1).
Take a look this issue on JBoss Jira for a workaround.
Good luck!
