We currently have an application that we have been running in Glassfish that we are migrating to use in Weblogic 12c. Leaving the existing project in place, I have moved all the code, resources, etc. to a new project where I've need to make some modifications related to the use of Weblogic and some of the weblogic provided extensions for JMS. One of the problems that I am experiencing is an issue related to the use of JPA.

Below is the error message I'm getting when attempting to access the admin page for the application:

<Jan 24, 2013 8:09:17 AM CST> <Warning> <HTTP> <BEA-101372> <There was a failure in application ServletContext@297087696[app:_auto_generated_ear_ module:WeblogicTaskServer path:null spec-version:3.0] when attempting to inject dependencies into tnt.wl.webapp.TaskStatusServlet. Dependencies will not be injected into this class.

Does anyone know if this is an issue in the project itself or does this seem to be a config or registration problem within Weblogic? Have very little experience with the use of JPA and persistence.

Thanks in advance for any input provided!

Hi Randy,

I think this question is well suited for the Oracle WebLogic Upgrade/Install/Environment/Migration forum, where you will probably get a quicker/better response.

https://forums.oracle.com/forums/forum.jspa?forumID=598

Give it a try, and also look for possible solutions over there.

Thanks,
Neil

Again, thanks Neil for the input. As stated in my email response I may put a follow up posting in the other forum, but will definitely keep that one in mind for anything further.
