JBoss classloading problem

I have a web application (war file) that works perfectly on tomcat. Now I need to put this same application to work on JBoss 4.2.2. There are other application running on the same JBoss instance.

The problem is when I try to deploy the war application on JBoss. This is the exception I'm getting:

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'postmanTask' defined in file [/Users/lorenooliveira/dev/jboss-4.2.2.GA/server/default/./tmp/deploy/tmp7909128750527758246vraptor-blank-project-exp.war/WEB-INF/classes/br/org/ampb/jobs/PostmanTask.class]: Unsatisfied dependency expressed through constructor argument with index 2 of type [br.org.ampb.util.ConfiguracoesSistema]: : Error creating bean with name 'configuracoesSistema' defined in file [/Users/lorenooliveira/dev/jboss-4.2.2.GA/server/default/./tmp/deploy/tmp7909128750527758246vraptor-blank-project-exp.war/WEB-INF/classes/br/org/ampb/util/ConfiguracoesSistema.class]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [br.org.ampb.util.ConfiguracoesSistema]: Constructor threw exception; nested exception is org.hibernate.AnnotationException: java.lang.NoSuchMethodException: org.hibernate.validator.ClassValidator.<init>(java.lang.Class, java.util.ResourceBundle, org.hibernate.validator.MessageInterpolator, java.util.Map, org.hibernate.annotations.common.reflection.ReflectionManager); nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'configuracoesSistema' defined in file [/Users/lorenooliveira/dev/jboss-4.2.2.GA/server/default/./tmp/deploy/tmp7909128750527758246vraptor-blank-project-exp.war/WEB-INF/classes/br/org/ampb/util/ConfiguracoesSistema.class]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [br.org.ampb.util.ConfiguracoesSistema]: Constructor threw exception; nested exception is org.hibernate.AnnotationException: java.lang.NoSuchMethodException: org.hibernate.validator.ClassValidator.<init>(java.lang.Class, java.util.ResourceBundle, org.hibernate.validator.MessageInterpolator, java.util.Map, org.hibernate.annotations.common.reflection.ReflectionManager)

Well, after some googling I found that this is a conflict between hibernate jars both in my war file and in the container.

Is there any way to tell JBoss: "Hey, my application doesn't need your hibernate libraries, all it needs is already within it."??

This is the complete version of my current hibernate.cfg.xml:

You probably have 2 versions of hibernate-validator on your classpath, so on tomcat one is loaded first and on jboss the other is loaded first. Try to remove one of them.

You can perform this kind of classloader hijinks when using an EAR, but I don't believe it works with WAR deployments (I'm willing to be shown otherwise, though).

This particular issue is, I believe, caused by Hibernate trying to auto-locate the Hibernate Validator library on the classpath. The version of Validator inside JBoss 4.2 is rather old, and not compatible with the new version of Hibernate in your WAR.

A more portable solution to your problem is to configure your application's Hibernate runtime to not try and auto-locate Hibernate Search or Hibernate Validator.

You do this by passing in two properties to the Hibernate config:

hibernate.validator.autoregister_listeners = false
hibernate.search.autoregister_listeners = false

It's not clear from your question how you're configuring Hibernate's SessionFactory, so it's up to you to figure out how to inject these properties

Partial solution is here: http://jaitechwriteups.blogspot.com/2008/08/how-to-upgrade-hibernate-in-jboss.html

The problem is that your hibernate library need a new version of hibernate-validator. Perhaps you put hibernate-validator-4.x.x. The problem with this version is that doesn't have the class org.hibernate.validator.ClassValidator, so you must put the version 3.1.0.GA instead 4.x.x.

When you do it, there a new problem, you need a jsr-303 provider: so you must put 4.x.x version too.

If you use maven, have 2 artifacts with same version is problematic, so you can use another jsr303 implementations (see jsr303 implementations) as a dependency. So in this case use:

            <!-- jsr 303 (javax.validation) provider-->
    <dependency>
        <groupId>org.apache.bval</groupId>
        <artifactId>bval-core</artifactId>
        <version>0.3-incubating</version>
    </dependency>

    <dependency>
        <groupId>org.apache.bval</groupId>
        <artifactId>bval-jsr303</artifactId>
        <version>0.3-incubating</version>
    </dependency>
