java.lang.NoSuchMethodException: org.hibernate.validator.ClassValidator Seam weblogic 10.3

Question

I have a big problem with Hibernate (use with seam) on weblogic 10.3.

When I publish my application, I get this error:

java.lang.NoSuchMethodExceptio         


        

Answer 1

If you happen to hit this issue on Weblogic Server, I solved this problem on Weblogic 10.3.0.0 with placing the package org.hibernate to prefer-application-packages at weblogic-application.xml in the EAR:

<weblogic-application>
   <prefer-application-packages>
      <package-name>org.hibernate.*</package-name>
   </prefer-application-packages>
</weblogic-application>

With a properly built application this will prevent Weblogic Server loading the older, conflicting library from the server's classpath and make it work as expected.

I solved this problem adding this two properties in my hibernate config.

<property name="hibernate.validator.apply_to_ddl">false</property> 
<property name="hibernate.validator.autoregister_listeners">false</property>

It happens when you use newer version of Hibernate in your application while pre-packaged hibernate jars (that come with jboss server) are of older version. For details on how to properly upgrade your application server's hibernate jars, read this.
