OK, I am trying to port an application from JBoss 4.0.1 to 4.2.3. I am now getting the error:
java.lang.IllegalStateException: Cannot obtain target bean for: JuniperLNServlet
I have searched extensively for this error both on Google and the JBoss site search function and cannot find anything. Any help would be appreciated. I am pretty much of a newbie with Web apps and services so I'm unsure of what I need to be looking at. To make things worse documentation for the application is nonexistent. JuniperLNServlet is a Web service. Because this is the first servlet defined in web.xml, it seems like the problem may be systemic and not specific to this servlet. To save space I am just including configuration code that is related to this servlet. If anybody has some ideas that makes them want to look at let me know and I will post that code.
