Weblogic 12.2.1 + Java 8 + Spring Data JPA + Hibernate 5.x Deployment conflict

Question

I am trying to deploy an EAR file using WebLogic 12.2.1 with Hibernate 5.x and Spring-data-jpa 1.9.4. The same configuration deployed fine on Weblogic 12.1.3. JPA 2.1 is used on both of them.

Weblogic is throwing a ClassNotFoundException and looking for the QueryDsl library which is optional with spring-data:

weblogic.management.DeploymentException: java.lang.ClassNotFoundException: com.mysema.query.types.path.PathBuilder

The manifest for Spring-data even references this jar as optional. Since Oracle publishes none of their source I can't exactly debug the problem .. it seems to throw an error long before my ApplicationContext actually initializes any of the Spring wiring.

The same configuration deploys fine on Websphere 8.5.5. There seems to be some kind of deployment conflict with using Weblogic 12.2.1 but I can't spot any other meaningful differences. Is anyone experiencing something similar?

Answer 1

I managed to overcome this error by explicitly adding querydsl-core and querydsl-jpa to my poms.

<dependency>
    <groupId>com.querydsl</groupId>
    <artifactId>querydsl-jpa</artifactId>
</dependency>

<dependency>
    <groupId>com.querydsl</groupId>
    <artifactId>querydsl-core</artifactId>
</dependency>
