Re: Cant validate dwr.xml on local machine

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>
