Firewall: Content type required

muellerg · Post by **muellerg** » Tue Apr 08, 2003 12:06 pm

Hi,

my image file is produced but not shown.
I set java.io.tmpdir on %CATALINA_HOME%\temp (Tomcat 4.1.12) and the images was produced there.

My 'jsp'-call is:
String graphURL = request.getContextPath() + "/DisplayChart?filename=" + filename;
<img src="<%= graphURL %>" width=400 height=300 border=0 usemap="#<%= filename %>">

The Firewall says: Content type required.

What should I do?
Thank you in advance!
George

Hi,

in your DisplayChart servlet add the line

response.setHeader("content/type", "image/...");

where image/... is your imagetype:

png for *.png files
jpeg for *.jpeg, *.jpg, *.jpe files
gif for GIF images

This should solve your problem.

Have more fun,
