Issues with servlet loading in JBoss7
Hi everyone,
I have recently migrated a JavaSE application (.war) to JBoss7. After spending the customary time to understand the new structure and configurations I have finally managed to run the app (including connect to the database). However there are several servlets that do not work and the only indication I have to the problem is a warning message in web.xml such as:
| Description | Resource | Path | Location | Type |
| servlet-class references to org.jboss.seam.servlet.SeamResourceServlet that does not implement interface javax.servlet.Servlet | web.xml | /MyApp/WebContent/WEB-INF | line 57 | Web XML Problem |
For sure this class implements the given interface. Also the compiler offers to "Configure problem severity for preference 'Invalid Server Class' ".
I have looked over the web a lot trying to find the way that JBoss7 handles the servlets but haven't been able to make any progress. Any help / suggestions would be greatly appreciated as I am so close to running.
Previously I was on JBoss 4.2.3 (all working fine).
Here is the full web.xml:
