filter-name element is missing in generated web.xml

One of our old applications uses Struts-1.2 and EJB-2, generated with xdoclet 1.2.3. Maven 1 is used to build the application using java 1.4. The application has been running in weblogic 8.1 without any issues.

Now we are upgrading to Weblogic 10.3.6 which runs on java 6. When the application is deployed to Weblogic 10.3.6 we encounter the following error. 

The error is weblogic.descriptor.DescriptorException: VALIDATION PROBLEMS WERE FOUND problem: 
cvc-minLength-valid.1.1: string length (0) is less than minLength facet (1) for filter-nameType 
in namespace http://java.sun.com/xml/ns/javaee:<null>

I understand this error is because the web.xml file is missing the filter-name element for a Filter class.

The problem is web.xml is generated by the application as part of the build process and I have no idea where or how to add the filter-name element value. What should I do to get the filter-name element to be added to the generated web.xml?

(Note: There is no problem when deployed to Weblogic8.1. This happens only when trying to deploy on weblogic10.3.6.)

Any help will be much appreciated.

Thanks.

Solution

  • Got it going.

    I had to add the following annotation to the filter class...

    @web.filter name="FilterClassName"

    web.xml generated the filter-name element after I added the above annotation.
