Java.lang.noclassdeffounderror:weblogic/security/subject/abstractsubject__web

A WebLogic data source is configured in spring, then the load applicationcontext.xml is initialized directly in the JUnit Test class when the spring Framework initializes the data source , you receive the following exception message:

Org.springframework.beans.factory.BeanCreationException:Error creating Bean with Name ' DataSource ' defined in URL [file :.. /portalweb/webcontent/web-inf/applicationcontext.xml]: Invocation of Init method failed; Nested exception is Java.lang.noclassdeffounderror:weblogic/security/subject/abstractsubject

After looking at the analysis, we learned that the Abstractsubject class exists in the Server/lib/weblogic.jar file of WebLogic Server, so you first add it directly to the current project's build path, and then run the JUnit Test, everything works.

Then remove the jar package from build path, run the current project directly, and find that everything is OK.

This shows that the Weblogc.jar file is only available when JUnit Test, so it is not necessary to place it in the Lib directory of project.

Note: The current development environment is WebLogic's workshop (Eclipse).
