How to change the security settings of tomcat5.0

Question

hi i am new to servlets. i am using tomcat5.0 to run my servlets.i have created two web applications under webapps directorywith the names ourwa and new ourwa.as part of ourwa i have developed a servlet with name Caller that includes another servlet named Calle of newourwa. to do this i got the Servlet Context object newourwa with the code below
ServletContext application=getServletContext( );
ServletContext newapplication=getContext("/newourwa" );
and i included Calle servlet using this newApplication with the code below
RequestDispatcher rd=newapplication.getRequestDispatcher("/calle");
rd.include(request,response);
i am not getting the ServletContext object of newourwa. so i am getting null pointer exception while running the servlet Caller.
i read the documentation on servlet context inteface.there is a method with the name get Context( ).in this method they clearly specified that "in a security conscious environment this method returns null".
please help me by giving answers to the following questions:
1)wat is the alternative to dispatch the request from one application to another application?
2)how to change the seurity settings of tomcat5.0?
thanks.

There has been a change in the Java security settings, see:
*http://kb.mozillazine.org/Java#Java_security_prompts

If you visit a website regularly then a possible workaround is to add the URL to the Java Exceptions Site List, see:
*"Why are Java applications blocked by your security settings?":<br>http://www.java.com/en/download/help/java_blocked.xml
