Here is the weblogic.xml in my application.

<?xml version="1.0" encoding="UTF-8"?>
<weblogic-web-app xmlns="http://www.bea.com/ns/weblogic/90"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.bea.com/ns/weblogic/90 http://www.bea.com/ns/weblogic/90/weblogic-web-app.xsd">
<context-root>/workspace</context-root>
<container-descriptor>
<prefer-web-inf-classes>true</prefer-web-inf-classes>
</container-descriptor>
</weblogic-web-app>

I have two ways to deploy my application,using installer or deploying it manually.
Using installer is ok,but I deployed it by myself,the problem came up.That's odd
I need the weblogic.xml to resovle another problem.
