getAttribute returning null
Having problem with a context parm. I have a servlet that queries for 300+
list of names, it then builds a select list. This list changes
infrequently, the jsp page is supposed to display the data from the servlet,
so being the absolutly brilliant person that I am I wanted that option list
built on startup, and then just have the jsp display the list.
I retrofitted the servlet to build the list, and then put
<%=application.getAttribute("listOfDealer")%> in the jsp, open the page and
wham -o awesome, great .. it doesnt work, all I see is null.
any thoughts

In addition to Tim Funk's advice, I'd suggest you post the code. A
one-letter typo can cause all sorts of headaches =)

No idea. But since you are using application (aka the servlet context), try
this to see whats in your ServletContext ...
<%
/* Yes - this is about to produce tables */
out.println("<table border='1'>");
out.println("<tr><th>Key</th><th>Value</th></tr>");
for (java.util.Enumeration e = application.getAttributeNames();
e.hasMoreElements();) {
Object key = e.nextElement();
out.print("<tr>");
out.print("<td>");
out.print(key.toString());
out.print("</td>");
out.print("<td>");
out.print(application.getAttribute(key).toString());
out.print("</td>");
out.print("</tr>");
}
out.println("</table>");
