Getting an error after deploying

Question

My web.xml file is this
<?xml version="1.0" encoding="UTF-8"?>
<web-app >
<servlet>
<description>This is the description of my J2EE component</description>
<display-name>This is the display name of my J2EE component</display-name>
<servlet-name>Rating</servlet-name>
<servlet-class>com.Mamatha.Rating</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>Rating</servlet-name>
<url-pattern>/Rating</url-pattern>
</servlet-mapping>
</web-app>
And the error i am getting is
<[BillingSystem.war]: Deployment descriptor "web.xml" is malformed. Check against the DTD: org.xml.sax.SAXParseException: cvc-elt.1: Cannot find the declaration of element 'web-app'. (line 6, column 52).>
Please help me out
Thanks

Answer 1

As Parvez mentioned it looks like the weblogic server is not able to pick up the custom classes.
Did you deploy the classes in RUN filesystem or PATCH filesystem ?
Have a look at Note 1577661.1 in metalink for detailed instruction on deploying the Business Logic Extensions
(Section 1.6.3.4: Developing OA Framework Business Logic Extensions):
