Sequence diagram generation (tomcat, mac os x 10.5.8, java 1.5.0_19-137)

[Shalon]

Greetings,

I was able to connect jTracert GUI (agent listening at 7007) with my
local instance of a running tomcat server. I have a webapp
(Something.war) deployed, and can actually run my tests at
http://localhost:8080/Something

However, I don't see any out put / sequence diagram being generated in
the GUI. Not even the sdx files on the filesystem either. Has anyone
run into this problem before ? Thoughts ? Is there any jTrace specific
log that I could look into for debug / providing more info if needed.

Thanks for your help in adv.

Regards,
Shalon

Here is the stack trace I notice upon basic tests. Looks like jTracert
is having difficulty handling reflection.

Shalon,

This issue is already fixed in SVN. See Issue 16:
http://code.google.com/p/jtracert/issues/detail?id=16
You can build jTracert from SVN yourself or wait for a next release.
