However, since the request is received directly by the J2EE Server, no configuration of the HTTP Server is required. Thus the flow of control is as follows: 1. The request to the Web application using the URL http://wtsc66oe.itso.ibm.com:80/CTGTesterECIWeb/ is received by the HTTP Transport Handler and passed to the Web container in the J2EE Server. 2. The URI CTGTesterECIWeb causes the default welcome page to be loaded, which is defined in the Web deployment descriptor (web.xml) to be the Java Server Page (JSP) index.jsp. 3. This index.jsp contains an HTML form that is then used to invoke the servlet CTGTesterECIServlet. 4. WebSphere next goes looking for an application whose defined servletmapping value matches that implied on the received URL and the servlet functions, as described in item 4 on page 267. 10.3.1 HTTP Transport Handler testing We tested both our J2EE application CTGTesterCCI and our servlet-based application CTGTesterECI with our non-secure CICS region SCSCPJA1. We deployed the applications as described in 10.2.5, “Deploying our sample enterprise applications” on page 258 and then used the following URLs to invoke the applications. ► http://wtsc66oe.itso.ibm.com:80/CTGTesterECIWeb
► http://wtsc66oe.itso.ibm.com:80/CTGTesterCCIWeb Results with ECIRequest/servlet application The initial HTLML page when running our CTGTesterECI Web application is shown in Figure 10-20. Figure 10-20 CTGTesterECI welcome page We supplied the following input parameters: CICS program name ECIPROG2 COMMAREA length 35 Encoding IBM037 Chapter 10.
