<h3>Troubleshoot: Enterprise applications</h3>
<p>Use the resources listed below to determine the cause of problems that occur
when running your application with the application server:</p>
<ul>
<li>
<p>Check the application server standard output and standard error log files
for errors. For information on the application server log files and where
they are located, see <a href="trblogs.htm">WebSphere Application Server
- Express log files</a>. </p>
</li>
<li>
<p>Add logging and tracing to your application with the JRas framework. See <a href="trbappsrvtrace.htm">Use
the application server trace service</a> for more information. </p>
</li>
<li>
<p>Add output to your Java code in the form of System.out.println() statements
to aid in debugging. The output from any System.out.println() statements
is written to the standard output log file for the application server in
which the code is running. For information on the application server log
files and where they are located, see <a href="trblogs.htm">WebSphere Application
Server - Express log files</a>. </p>
</li>
<li>
<p>Read the release notes. See <a href="http://www-1.ibm.com/servers/eserver/iseries/software/websphere/wsappserver/express/docs/relnotesexp50.html" target="_new">WebSphere Application Server - Express Release Notes</a> <img src="www.gif" width="18" height="15" alt="Link outside Information Center" border="0"> for
