I'm having the following problem ...

Error that occurs:
java.lang.SecurityException: class "javax.persistence.EntityListeners" 's signer information does not match signer information of other classes in The Same package

My structure of applications

Server tomcat 6 + Hibernate 3.6 + JPA
App1 - java 6

Jars of hibernate 3.6 final are in the directory tomcat/lib

The error occurs when the following line of code is called just after loading the mappings:
Configuration conf = new AnnotationConfiguration().Configure();
factory = conf.buildSessionFactory() -> row that the error occurs

If I put the hibernate jars in the directory App1/WEB-INF/lib everything works but must remain on jars tomcat/lib because n# applications using hibernate
