Problem in deploying a war file in Weblogic 7.0

[rajihari]

Hi,
We developed our application in Weblogic 7.0. It is working fine. I tried deploying the exploded directory in weblogic 7.0, it also works fine. But when v tried to deploy the war file in the Weblogic 7.0, I'm getting the following error.

We are following the dir structure as specified in weblogic documentation. We have placed the helper .jar files in /Web-Inf/lib dir.

Any clue would be of great help. Pls this is very urgent.

Thanks

Hi,
V have solved this problem.
The problem was in my StartupServlet.
In the servlet v used the following to find the root of the application. After finding the root of application, v used the value to access a file stored in that path. Like

String appPath = getServletContext().getRealPath(&quot;/&quot;
FileInputStream fis = new FileInputStream(appPath + &quot;/WEB-INF/config/appConfig.cfg&quot;

This getRealPath() method works fine if v use the exploded directory format. But it throws Null when v use the .war file to deploy.

To avoid this problem, don't use getRealPath method, if u r using .war format for deployment.

Instead, use getResourceAsStream() method of ServletContext to convert the file to Stream. (i.e) use something like this.

InputStream fis = getServletContext().getResourceAsStream(&quot;/WEB-INF/config/appConfig.cfg&quot;

Hope this helps. Pls get back for any clarifications.
