Your web.xml file is malformed, can you post it here?

The elemnet persistence-context-ref belongs to Java EE 5. Your web.xml should be using http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd schema not http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd

Changing only this will not fix the problem, your project was created for 1.4 spec and that tag is for Java EE 5 spec.

Recreate the project with the correct spec version or don’t use that tag.

The header of the web.xml file must look like this:
```
xmlns="http://java.sun.com/xml/ns/javaee"  
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.5"  
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee  
    http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
```
It looks like your web.xml is malformed or out of order. Can you post it here and maybe we can eyeball the problem?

The web.xml is located in a directory called WEB-INF
