I have my javaproject's war file. I need to integrate flex 2 with
the same.
What I have done, I have copied flex folder to WEB-INF folder of my
java project's war and copied and pasted all jars from lib folder of
flex.war to javaproject.war's lib folder.
And top of it I have made some entries in web.xml file of my
javaproject.war. the entries are as:
------------ web.xml -----------------

I have made the enteries mentioned with sanjay sharma. After
restarting my JBOSS server, when I try to access my mxml page, It
shows the following exception:
SEVERE: Allocate exception for servlet FlexMxmlServlet
java.lang.NullPointerException.
Please pull me out from this problem.
Thanks in advance.
Sanjay Sharma
