A browser connects to the webserver that is running the servlet. jt400Servlet.jar and jt400.jar files reside on the webserver because the servlet classes use some of the access classes to retrieve the data and the HTML classes to present the data. The webserver is connected to the iSeries server where the data is.</p> </div> <div class="section"><p><strong>Figure 1: How servlets work</strong></p> </div> <div class="section"><p><img src="rzahh585.gif" alt="How servlets work" /> <img src="c.gif" alt="Image description" /><a href="rzahh585.htm#rzahh585">Long description of Figure 1: How servlets work (rzahh585.gif)</a></p> </div> <div class="section"><p>There are four types of servlet classes included with IBM Toolbox for Java:</p> </div> <div class="section"><ul><li><a href="servauth.htm#servauth">Authentication</a> classes</li> <li><a href="rowdata.htm#rowdata">RowData</a> classes</li> <li><a href="rowmeta.htm#rowmeta">RowMetaData</a> classes</li> <li><a href="convert.htm#convert">Converter</a> classes</li> </ul> </div> <div class="section"><p><strong>Note</strong>: The jt400Servlet.jar file includes both the <a href="html.htm#html">HTML</a> and Servlet classes.
