Migration problem Tomcat version 6 to version 7

Guys,

I have a servlet that connects to an (OpenEdge) appserver and passes the response from the appserver on the web stream.

This servlet works beautifully in Tomcat 6.
In Tomcat 7 however it fails to work.

The way the servlet is deployed in Tomcat 6 was:

- Deploy CgiAlt.war in webapps directory
- Start Tomcat 6 (CgiAlt.war get exploded into CgiAlt directory)
- Everything works great

When I follow the same procedure in Tomcat 7 the .war does get exploded but the servlet does not work.

I am attaching a zip file with the following (the zip extension was renamed to .bmp so you have to rename it back to a zip):

1) Log files Tomcat 6
2) Log files Tomcat 7
3) context.xml and web.xml Tomcat 6
4) context.xml and web.xml Tomcat 7

Can anybody tell me why the servlet does not work in Tomcat 7 and what I can do about it.
Any help is greatly appreciated.

Assuming everything is same (in terms of the content of each deployed files) in both servers, Are you able to deploy a simple sample application and get it to run in Tomcat 7?

I was able to deploy and run a hello world servlet in TOMCAT 7

Is the context you are talking about "CgiAlt" and it does not depends on anything else (i.e.:external to the context)?

The actual servlet that does not work is hosted at CgiAlt/Cgi.
I am not sure what you mean by "depending on something external to the context".
In Tomcat 6 I just deployed CgiAlt.war started up Tomcat ane everything worked.
Does that answer your question?

What is the file CgiAlt.xml which is being read as per your Tomcat 6 log files are concerned? What is the purpose of this and where is it located? And in your Tomcat 6 logs there's no evidence that a context called "CgiAlt" is deployed successfully either?
And what options you tried deploying the app in Tomcat 7 (i.e.: unpack the WAR inside webapps and restart the tomcat)?
