I have JSP A that includes JSP B like this:
<jsp:include page="../anotherFolder/B.jsp">
<jsp:param name="pathToRootContext" value='../' />
</jsp:include>

In JSP B i have the following:
String pathToRootContext = request.getParameter("pathToRootContext");

The value i get in the pathToRootContext is "..%2f"

I tried the following but it didn't help:
<servlet-container name="default" default-encoding="UTF-8">
<jsp-config development="true" java-encoding="UTF-8"/>
</servlet-container>
