Cant validate dwr.xml on local machine

[Gregorgio]

Hello I am trying to validate my dwr.xml on my local machine but its throwing a null pointer.
I am positive that my path to the DTD is correct.
If I use <!DOCTYPE dwr PUBLIC .......(URL TO DTD) it works
but when I try <!DOCTYPE dwr SYSTEM ....(PATH TO DTD)

Please help, its urgent.

this is my dwr.xml
<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE dwr SYSTEM "/usr/tomcat/webapps/CARS/WEB-INF/dwr20.dtd">

<dwr>
  <allow>
    <create creator="new" javascript="OrgSuggestions">
     
    </create>
  </allow>
</dwr>

Why not use a PUBLIC doctype?

<!DOCTYPE dwr PUBLIC
    "-//GetAhead Limited//DTD Direct Web Remoting 2.0//EN"
    "http://directwebremoting.org/schema/dwr20.dtd">

dwr.jar contains a copy of the dtd and it won't read the network to find it.

The reason I want to use SYSTEM instead of PUBLIC is because my app might not be able to reach http://directwebremoting.org/schema/dwr20.dtd since I am in the Intranet and wont have access to the Internet, but if you are telling me that it actually wont go out to the network to search for the DTD then I am safe.

Thanks!!

DWR configures an EntityResolver before loading the dwr.xml file so it resolves DTDs from the JAR and not the network.
