[reza x]

hi all

i am using weblogic version 8.x for my cocoon application deployment,but i have a problem in cocoonServlet initilization.the exception is as follows:

 

 

java.lang.NullPointerException
at org.apache.cocoon.servlet.CocoonServlet.init(CocoonServlet.java:342)
at weblogic.servlet.internal.ServletStubImpl$ServletInitAction.run(ServletStubImpl.java:1070)

I think the problem is that My webApp has been deployed as .war file and the following line

 

      this.servletContextPath = this.servletContext.getRealPath("/");

returns null ,so the exception is occured.

can any one help me to solve this problem.

 

thanks alot for your attention

Best Regards.
