louyaoluan

　　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]   ]
 
Solutionè Set <prefer-application-packages/> inweblogic-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. Cleanand 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.
