HTTP Server (powered by Apache)</h1>
<div><p>This scenario discusses how to configure ASF Tomcat to use an in-process
servlet.</p>
<div class="important"><span class="importanttitle">Important:</span> Information
for this topic supports the latest PTF levels for HTTP Server for i5/OS .
It is recommended that you install the latest PTFs to upgrade to the latest
level of the HTTP Server for i5/OS. Some of the topics documented here are
not available prior to this update. See <a href="http://www-03.ibm.com/servers/eserver/iseries/software/http/services/service.html" target="_blank">http://www.ibm.com/servers/eserver/iseries/software/http/services/service.htm</a> <img src="www.gif" alt="Link outside Information Center" /> for more information. </div>
<div class="section"><h4 class="sectiontitle">Scenario</h4><p>The JKL Toy Company (a fictitious company)
wants to take an existing Java™ servlet named <strong>jklservlet.class</strong> and
enable it to run, in-process, using the ASF Tomcat servlet engine with the
HTTP Server (powered by Apache). The <strong>Servlet and JSP Enablement</strong> wizard
will be used to modify the existing HTTP Server (powered by Apache), <strong>JKLTEST</strong>.</p>
