Sorry for my English. I have one problem. I have a EJB and also a web application. This WebApplication have a client to connect to ejb.When the query into ejb the end, and result return my application, I get the following error:

[org.hibernate.proxy.pojo.javassist.JavassistLazyInitializer] (default task-13) HHH000142: Javassist Enhancement failed: mymodel.object: java.lang.RuntimeException: by java.lang.NoClassDefFoundError: org/hibernate/proxy/HibernateProxy

Yes, in my pom (EJB) i put:

	<dependency>
	<groupId>org.jboss.seam</groupId>
	<artifactId>jboss-seam</artifactId>
	<version>2.2.0.GA</version>
	<exclusions>
	<exclusion>
	<groupId>javassist</groupId>
	<artifactId>javassist</artifactId>
	</exclusion>
	</exclusions>
	</dependency>

but I always get the same error. Also exclude from jboss-deployment-structure.xml?

Can you post a complete exception call stack?

Is your application using JPA or the Hibernate API?

The query is made on an object person. This Object Person have into model hibernate, @ManyToOne(fetch = FetchType.LAZY) . The response of the method,without still arriving to the web application, i get this error.

smarlow Jan 25, 2016 9:21 PM (in response to salvuzzo)

I think that you need to add an application dependency on the Javassist static module in WildFly. Does your application have a MANIFEST.MF? Perhaps you have something like the following already in your MANIFEST.MF:

Dependencies: org.hibernate

You probably need to add the org.javassist static module to your MANIFEST.MF file. See example below:

Dependencies: org.hibernate, org.javassist

Your other changes to avoid adding the Javassist classes directly into the application are correct.

Documentation link that describes the "Dependencies" in MANIFEST.MF is here.

Yes, into my jboss-deployment-structure.xml i have dependencies with module "org.hibernate". I should remove org.javassist ? My deployment my ejb is:

<jboss-deployment-structure>
    <deployment>
        <dependencies>
            <module name="org.hibernate" />
        </dependencies>

            <module name="org.javassist" />
        </exclusions>
    </deployment>
</jboss-deployment-structure>

but not having worked the JavassistLazyInitializer (my query go without FetchMode.JOIN)

Your application needs a dependency on the "org.hibernate" module and the "org.javassist" module. Both of which are required for Hibernate applications. You can try the below change:

<jboss-deployment-structure>

    <deployment>

        <dependencies>

            <module name="org.hibernate" />

            <module name="org.javassist" />

Have you tried adding the dependencies via your MANIFEST-MF? Not sure if that will make help.

Can you also check that your not including the same dependencies in your application (e.g. "jar tf yourapp.war" will show the contents).

Can you remove Javassist from the jboss-deployment-structure (doesn't need to be in the manifest + jboss-deployment-structure).

Please show us the contents of your application.war, You can use the "jar tf yourApp.war" command to get the contents.

I do not know what it means that command, however I do not understand because putting "@Fetch(FetchMode.JOIN)" in @ManyToOne works. And 'as if he needed the transaction, even if I do not make use of the object
