<h1 class="topictitle1">Debug servlets</h1>
|
||
|
|
<div><p>Debugging servlets is a special case of debugging classes loaded
|
||
|
|
through a custom class loader. Servlets run in the Java™ runtime of the IBM<sup>®</sup> HTTP Server. You have several options
|
||
|
|
to debug servlets.</p>
|
||
|
|
<div class="section"><p>The easiest way to debug Java programs and servlets that run on your iSeries™ server
|
||
|
|
is to use the IBM iSeries System
|
||
|
|
Debugger. The IBM iSeries System
|
||
|
|
Debugger provides a graphical user interface that enables you to more easily
|
||
|
|
use the debugging capabilities of your iSeries server.</p>
|
||
|
|
<p>For more information
|
||
|
|
about using the iSeries System
|
||
|
|
Debugger to debug and test Java programs and servlets that run on your iSeries server,
|
||
|
|
see <a href="../rzamq/rzamqmain.htm" target="_blank">IBM iSeries System
|
||
|
|
Debugger</a>.</p>
|
||
|
|
<p>Another way to debug servlets is by following the instructions
|
||
|
|
for <a href="debugcla.htm">classes loaded through a custom class loader</a>.</p>
|
||
|
|
<p>You
|
||
|
|
can also use the interactive display of your server to debug a servlet by
|
||
|
|
completing the following steps: </p>
|
||
|
|
</div>
|
||
|
|
<ol><li><span>Use the <samp class="codeph">javac -g</samp>command in the Qshell Interpreter
|
||
|
|
to compile your servlet.</span></li>
|
||
|
|
<li><span>Copy the source code (.java file) and compiled code (.class file)
|
||
|
|
to /QIBM/ProdData/Java400.</span></li>
|
||
|
|
<li><span>Run the Create Java Program (CRTJVAPGM) command against
|
||
|
|
the .class file using optimization level 10, OPTIMIZE(10).</span></li>
|
||
|
|
<li><span>Start the server.</span></li>
|
||
|
|
<li><span>Run the Start Service Job (STRSRVJOB) command on the job where
|
||
|
|
the servlet runs.</span></li>
|
||
|
|
<li><span>Enter STRDBG CLASS(myServlet), where myServlet is the name of your
|
||
|
|
servlet. The source should be displayed.</span></li>
|
||
|
|
<li><span>Set a breakpoint in the servlet and press F12.</span></li>
|
||
|
|
<li><span>Run your servlet. When the servlet hits the breakpoint, you can
|
||
|
|
continue debugging.</span></li>
