问题
I'm having this issue while developing portlets:
Caused by: javax.servlet.ServletException: java.lang.AbstractMethodError: javax.servlet.jsp.PageContext.getELContext()Ljavax/el/ELContext;
I don't know anymore, what I can do.
My portlet set-up is as follows:
- in web.xml:
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" - in my jsp:
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %>
I also have some Maven dependencies in the POM file including portlet-api 2.0, jsp-api 2.1, servlet-api 2.5, jstl 1.2, el-api 2.2 and el-impl 2.2 ...
Anyone has an idea what to do?
