Answer 1

Please try the following suggestions in that order:
1. Check if the WAR file was built with jar files and tools from WebLogic10.3 OR WebLogic9.2. The weblogic jars that you use to build the application should be from the installation where you are trying to deploy the application. Not necessarily from the same machine, I meant to say should be of the same major version. If this does not resolve the issue, then please follow suggestion#2
2. Check the line, <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"> in your web.xml. If "web-app" version element says 2.5, try changing it to 2.4 and rebuild the WAR application and try deploying. If this does not resolve the issue, then please follow suggestion#3
3. Perhaps the Weblogic Server does not have access to http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd to load the XSD elements ? Check that by accessing that XSD from the machine where weblogic server is running.
These suggestions are based on the suspicions that I have listed in my previous post.
