Log files are not created for the desktop client launched
through Web Start unless you enable tracing for the JRE.
Before you begin
The logs for the Web Start client are located
in a different place than logs for the browser client and for the
desktop client installed from the media. On Windows computers, the logs for the Web Start
client are located in the
C:\Documents and Settings\Administrator\Application
Data\IBM\Java\Deployment\log or
%USERPROFILE%\AppData\LocalLow\IBM\Java\Deployment\log directory.
On Linux and UNIX computers, the logs are located in the
.java/deployment/log directory
of the home directory of the user ID under which the Java™ JRE was installed. Java Web Start will create a uniquely named
trace file for every independent launch of the application. The files
are named
javaws.nnnnn.trace,
where
nnnnn is an arbitrary
five-digit identifier.
