RequestDispatcher.include() results in NullPointerException
Summary: RequestDispatcher.include() results in
NullPointerException
Product: Tomcat 5
Version: 5.0.19
Platform: PC
OS/Version: Linux
Status: NEW
Severity: Major
Priority: Other
Component: Catalina
AssignedTo: tomcat-dev@jakarta.apache.org
ReportedBy: rickkw@yahoo.com
Background:
* JBoss 3.2.4RC1 w/Tomcat 5.0.19.
* Two webapps: /com.loudcloud.owm.usrmgr, /com.loudcloud.owm.shared
* Inside page /com.loudcloud.owm.usrmgr/domain.jsp, it includes the content of
another JSP from another webapp /com.loudcloud.owm.shared/header.jsp. It does
so by getting a request dispatcher
ServletContext ctx2 =
pageContext.getServletContext().getContext("/com.loudcloud.owm.shared");
RequestDispatcher dispatcher = ctx.getRequestDispatcher("/header.jsp");
dispatcher.include(request, response)
This results in the following NullPointerException in Catalina (see stack trace
below). Also worth mentioning is that both webapps /com.loudcloud.owm.shared
and /com.loudcloud.owm.usrmgr have a Filter set up in the web.xml. Only the
filter in the /com.loudcloud.owm.usrmgr/domain.jsp request was invoked. The
filter /com.loudcloud.owm.shared/header.jsp was not invoked. Is that the
correct behavior with Servlet 2.4?
