List Denizens:
I'm having trouble displaying an image via HTML generated from a
servlet running in JBoss/Jetty. I can display the image OK if it's
from a JSP but not (so far) from a servlet. In the case of the
servlet, the alt text appears. My guess is it's a configuration
problem, but I don't know what to do to change the configuration.
Situation:
JBoss/Jetty 3.0.
WAR file nozama.war deploys successfully on JBoss.
When servlet is run, the following exception appears on the log:
09:30:46,458 INFO [Jetty] nozama.servlets.HelloServlet: init
09:30:46,465 INFO [Jetty] Dynamic load 'nozama.servlets.HelloServlet' at
/servlet/nozama.servlets.HelloServlet
09:30:46,944 WARN [Jetty] WARNING:
java.lang.ClassNotFoundException: image.jpg
at java.net.URLClassLoader$1.run(URLClassLoader.java:198)
at java.security.AccessController.doPrivileged(Native Method)
at java.net.URLClassLoader.findClass(URLClassLoader.java:186)
at org.mortbay.http.ContextLoader.loadClass(ContextLoader.java:228)
. . .
This gives the appearance that Jetty is interpreting the image name as
a Java class rather than a JPEG. What must I do in order to make it
load an image rather than try to load a class?
