IE
I have a Jsp files that displays some elements of an xml file. When i remove an element of the xml file and i reload the jsp file the element that i removed before still appears.
I am using resin web server, and when i shut it down and then turn it on the element disapears.
Is there a solution to this problem??
I have tried lots of different ways but none of them had work.
excuse my english please.

There is no solution. :-(
Sorry, but that's life.

maybe you could try this...
just add this piece of code to your jsp file diplaying the xml file and let me know if it works..
<%
response.setHeader(&quot;Cache-Control&quot;,&quot;no-cache&quot;);
response.setHeader(&quot;Pragma&quot;,&quot;no-cache&quot;);
//prevents caching at the proxy server
response.setDateHeader (&quot;Expires&quot;, 0);
%>

or you could try to add this piece of code into your html..
<html>
<head>
<meta http-equiv=&quot;Expires&quot; CONTENT=&quot;0&quot;>
<meta http-equiv=&quot;Cache-Control&quot; CONTENT=&quot;no-cache&quot;>
<meta http-equiv=&quot;Pragma&quot; CONTENT=&quot;no-cache&quot;>
</head>
let me know if it works...

i just went through some details about the resin webserver..
i found that &quot;Sessions should be disabled for caching.&quot;
Now in your case u want to avoid caching..
so u can as well enable sessions in your program to avoid the problem..
try and let me know..

Ok i guess that aint gonna be the solution...
i dont know much about Resin ...
but as for weblogic...everytime i make changes to the jsp..
it is re-compiled and then loaded...
guess that does not happen with resin...
maybe the server keeps the old copy of the code until u re-start the server..
I guess GT500FOMOCO is right ....

Resin does recompile pages, the problem is that the JSP is not changing. The page that is changing is an XML document.

My question is: Is the XML document being included or is it being parsed thru Java in the JSP page?

Since I don't fully understand what action is taking place I can only have one minor suggestion: Force a recompilation of the JSP page by making a small change (like adding or deleting a space). Wushutwist
