Help troubleshooting?

Thread view:

I could use some direction in how to begin troubleshooting a Java
problem. This may not be the appropriate group, I appreciate
suggestions for other forums or support groups.

I have a set of servers running Windows Server 2003 x64. On all but
one of these servers, logged on as a non administrator, when I attempt
to launch a Java applet through Internet Explorer the splash screen
(for the applet) will briefly appear, then close. If I attempt to
launch the Sun Java Console in IE, then IE itself closes (and there's
nothing in the  Event Log). If I am logged on as a local
administrator, none of these problems manifest. On the one server
where I don't have this problem, I am running an older version of Java
- for the rest of the servers, I'm running the most up-to-date
version.

Without the ability to even open the console to turn on logging, I'm
not sure how to proceed with troubleshooting. I've gone so far as to
try SysInternal ProcessMon, but it doesn't seem too useful for Java
apps. :)

Just a wild guess - check the options of your IEs for which JVM they use
(Microsofts or Suns). Otherwise it could be a version problem (different
JREs on different machines).

Turn on the Java console. See http://mindprod.com/jgloss/console.html
for how to do it is your browser.  You will then at least get some
error message.

If you have the source for the applets, convert them to hybrids and
debug them as applications.  See

try alternate browsers. Turn on the console before you start.
