Generated JSP reports and context-param in web.xml

Question

I have what I believe to be a problem when using .jsp files generated from reports builder (actually, it looks as if the problem is in the reports tag library. When adding a context-param to web.xml, I get an error when compiling the following line:
<%@ taglib uri="/WEB-INF/lib/reports_tld.jar" prefix="rw" %>
Error(1): oracle.xml.parser.v2.XMLParseException: Invalid element 'context-param' in content of 'web-app', expected elements '[taglib, resource-ref, security-constraint, login-config, security-role, env-entry, ejb-ref]'.
Note that I can read the context param and no other JSP pages seem to care, just those with the Reports Tag library.
Regards,
Jeff

Ben -
There can be init params for the servlet or for the servlet context. For the servlet, this looks like:
<servlet>
<servlet-name>InitServlet</servlet-name>
<servlet-class>package1.InitServlet</servlet-class>
<init-param>
<param-name>message</param-name>
<param-value>Hello From Initialization Parameter</param-value>
</init-param>
</servlet>
in the web.xml file, and is accessed using:
public void init(ServletConfig config) throws ServletException
super.init(config);
message = config.getInitParameter("message");
For a servlet context init param, you define it as you did using the web.xml settings editor:
<context-param>
<param-name>hello</param-name>
<param-value>hi</param-value>
</context-param>
This is accessed using:
public void init(ServletConfig config) throws ServletException
super.init(config);
message1 = config.getServletContext().getInitParameter("hello");
Hope this helps,
