MyEclipse: Version 5.0
Hibernate: 3.1
Struts: 1.2.7
Web Container: Resin 3.0.19
I am also using tiles.

I have a web-project that works until I add Hibernate capabilities. I don’t even access the the HibernateSessionFactory, all I do is add Hibernate Capabilities, Configure a Database Connection and Create a Session Factory. When I deploy the app, it throws a javax.servlet.UnavailableException
at org.apache.struts.action.ActionServlet.init(ActionServlet.java:368).

As I said earlier, I do not even start a Hibernate Session or even access the class anywhere in my code. This app used to work before I added Hibernate capabilities.

The full stack-trace is below:

A quick update.

I was able to recreate this problem using the latest production Struts distribution (1.2.9).

This problem does not crop up when I am using Struts 1.1.

To recreate this problem, Create a Web-Project, Add Struts (1.2) capabilties and Hibernate (3.1) capabilities. Then deploy to a Resin server. If you want, you can verify that the application deploys before Hibernate capabilities are added and fails to deploy after Hibernate capabilities are added.

I am going back to Struts 1.1 until this issue is resolved.

Another question, to go back to Struts 1.1, is it enough if I just copy the 1.1 jars into my project/webroot/web-inf/lib folders and change all the DTD’s to Struts_1_1 from Struts_1_2 or are there some internal My-Eclipse settings that I will have to tune?
