[OpenSIPS-Users] WeSIP - Problem with <jsp:include> and RequestDispatcher

[Viliam Pucik]

Hello,

there is a problem when using <jsp:include page"some/page.jsp"> tag in
a JSP page in WeSIP.

To reproduce the error:

For example: Download click2call application and put Test.jsp page
with the following content in it:

<jsp:include page="Click2Dial.jsp" />

into the same folder where Click2Dial.jsp is located. It will show
"HTTP Status 500 - Internal Server Error" after opening URL
http://localhost:8080/c2c/Test.jsp.

The error in a log file:

Also the similar error happens when using

RequestDispatcher dispatcher =
getServletContext().getRequestDispatcher("/jsp/Click2Dial.jsp");
dispatcher.forward(request, response);

in a servlet.

It's a little bit frustrating :(
