This is all working fine, apart from one issue: a call to HttpServletRequest.getServletContext() returns "/"
rather than "" - the servlet API says "" is correct . If the default context is defined in
server.xml, getServletContext() returns "" a
You must call super.init(...) in your init method.

Wanted to know if this assumption is valid in most jsp containers:
Is calling getServletContext() ( instead of
getServletConfig().getServletContext() ) assuming that the servlet
generated from the jsp will be derived from HttpServlet ?
This works ( in Tomcat ) because HttpJspBase derives

Hi all,
I am trying to share an object from a servlet to a JSP by using the
getServletContext().setAttribute() method in the init() of my servlet. I am
able to return the context from the JSP page but am unable to retrieve the
attribute (getAttribute() returns null).

dispatch the request over to the JSP I get null back from the
getServletContext() call. Is there anything in the configuration I have
supplied which would stop this context being created appropriately? I would
presume that a servlet would necessarily be part of a ServletContext, and
therefore it
found it... I didn't call super.init(config) in the init() method

I've just installed tomcat 3.2.2 and have the following problem.
I want to call getServletContext() from a servlets service method but
get the folowing exception
*Internal Servlet Error:*
java.lang.NullPointerException

Hi,
getAttribute returns a java.lang.Object so you have to cast it to
java.sql.Connection. You will also need to import java.sql.
<%@ page import="java.sql.*" %>
...
<% Connection Conn =
(Connection)getServletContext().getAttribute("dbConnection"); %>
Make sure
I guess to save any object to a session, the object has to implement serializable
interface.

Hi, I have a problem I have been trying to solve for a very long time. I
first have a initialization servlet set by tag. In this
servlet I create a database connection and pass it to the ServletContext like
this.
getServletContext().setAttribute("dbConnection",dbConnection);

Yup, the jsp is in webapps/jdbctut/jdbctut.jsp
This is where i get the err.

The usual reason for this is a failure to call super.init()
in your servlet
Hi,
I am trying to get a servlets context
