Drillable Reports With Tomcat 6 and IE web Browser

[ajaysharma]

Hi All,

Please help me.

Issue: I have created some drillable reports that were working fine with JDK 1.5 and Tomcat 5.5: for IE web browser.

I am tring to run same reports on on jdk 6 and tomcat 6. But drilled image does not change in Internet Explorer.

 Tomcat Version Used: apache-tomcat-6.0.26

Obervations:

==========

1. Image: i am getting in internet explorer on drilling: is old one. On pressing: Ctrl+F5 drillled image changes. Drillable reports works fine in Mozilla Firefox.

2. Weird Cause may be: this may issue with flushing of image: "img src="image?image=img_0_0_4";

As Tomcat 5.5 uses Jasper libs: jasper-compiler-jdt.jar, jasper-compiler.jar, jasper-runtime.jar

And Tomcat 6 uses Jasper libs:jasper-el.jar, jasper-jdt.jar, jasper.jar.

Tried to implement but not worked; for Obervations 1

==============================

I put the following line in JSP so that image don't come from Browser cache.

<meta http-equiv="expires" content="0">
<meta http-equiv="Pragma" content="no-cache">
<meta http-equiv=Content-Type content="text/html; charset=windows-1252" />
 <%
response.addHeader("Cache-Control","no-store");
response.setHeader("Cache-Control","no-cache"); //HTTP 1.1
response.setDateHeader ("Expires", -1); //prevents caching at the proxy server
%>

I think i have to clear net.sf.jasperreports.j2ee.servlets.ImageServlet cache. Looking for how to do it.

Caching problem is fixed by using following line:

exporter.setParameter(JRHtmlExporterParameter.IMAGES_URI, "/image?x=" + System.identityHashCode(jasperPrint) + "&image="«»); Thanks, Ajjuuu
