Migrate Weblogic 9.2 to Weblogic 11g : Spring Application

Here I would like to list the problems I met during Spring application migartion from Weblogic server 9.2 to Weblogic Server 11g.

 

Hibernate cannot be loaded properly

     [java] 11:53:29,008 ERROR [SessionFactoryImpl] Error in named query: DDFTree.findDeviceModelByDDFTree

 

     [java] org.hibernate.QueryException: ClassNotFoundException: org.hibernate.hql.ast.HqlToken [

     [java]       SELECT model FROM com.wgu.domain.ModelImpl model

     [java]         join model.ddfTrees tree

     [java]         WHERE tree = ?

     [java]   ]

 

Solutionè Set <prefer-application-packages/> in weblogic-application.xml to configure. See Weblogic Class loading.

 

JSP page cannot be accessed

Solutionè Problem comes because the old domain is created for WLS 9.2. Clean and re-launch domain creation. 

 

 

 

Classes cannot be accessed/resolved because of not including in weblogic.jar in 11g

This is mainly happened in development ENV because some referenced libraries are not in class path. For example:

 

• weblogic.descriptor.SettableBean
• weblogic.descriptor.DescriptorBean

Solutionè Add Jars:

 

• /modules/com.bea.core.descriptor_1.9.0.0.jar
• /modules/com.bea.core.datasource6_1.9.0.0.jar
• /modules/com.bea.core.utils_1.9.0.0.ja

MBean Server ObjectName

To be updated later.
