Errors with webapps in WebLogic 9.2

Question

Hi.
Well, the problem is I when I access to the webapp it gives me a error. The app is deployed and started without any problem.
The first war I tested gives me that error when I access to the app.
Error 500--Internal Server Error
java.net.MalformedURLException: The path for getResource() must begin with a '/'

You can download the war here war
After that I thought I was doing something wrong so I downloaded jeexplorer , installed the war and finally started it. But when I try to access to the webapp it gives me that error:
<!--

I only want to have a manager with the basic functions to upload, download and execute commands...
Thanks for any help and sorry for my bad English.

Thanks David and weblogicRocks..
David,
I have installed the workshop also during installation. Actually I have searched for the class which is missing from the weblogic 9.2 installation folder. The missing class is is in different package path in weblogic 9.2 (knex81.jar) as shown below. Also, this class is generated by workshop while building in 8.1. So, I think I have to rebuild the work file in 9.2 to avoid referring to this class.
Missing Class location (weblogic 8.1) (knex.jar): com/bea/wlw/runtime/core/bean/SLSBContainerBean
Missing Class location (weblogic 9.2) (knex81.jar): com/bea/wlw/knex/runtime/core/bean/SLSBContainerBean
weblogicRocks,
I saw in the weblogic site that the webservices built from 8.1 will still work in 9.2 with out the need for changing the code. Pls, let me know whether I need to rebuild them on 9.2. If yes, I have used .jws files(sample class definition below) for my webservices and I came to know that in 9.2 new jws annotations are added, do I need to change my source code to add any new annotations so as to work in 9.2? Also, I have used wlwBuildTask using Ant to build the code in 8.1 and this task is not available in 9.2. Let me know what all I need to change for webservices created from workshop to migrate to 9.2. I am really struggling in resolving the issues as it is very urgent for me. Appreciate you quick response.
Below is my .jws webserice class definition.
public class MyWebService implements com.bea.jws.WebService
private String reqImpl;
* @common:operation
* @jws:conversation phase="none"
public String submitRequest(String var)
<Method Logic>
