Enter some text into the text field on the HTML page and submit it by clicking the POST button. Along with the text you entered, other parameters are submitted to the simpapp servlet class running in WebLogic Server.

The following is the relevant section from the simpapp.html file that describes the HTML form:

<form name="simpapp" action="simpapp" method="post">
<input type="hidden" name="SVCNAME" value="TOUPPER">

<table bgcolor=#dddddd border=1>
<tr>
<td>Type some text here and click the Post button:
<input type="text" name="string">
</td></tr>

<tr>
<td align=center><input type="submit" value="Post!">
</td></tr>

This HTML form specifies two input fields: the text you enter and a hidden field. In this example, the value of the hidden field actually specifies the name of the Tuxedo service to be invoked. Although putting the name of the Tuxedo service within the HTML page is flexible and efficient, it is not recommended for production use for security reasons. In this HTML page, you can submit an HTTP request specifying a different service name as the hidden field.

When the WebLogic Server receives the HTTP form request, it invokes the doPost() method of the simpapp servlet and passes the form data into an HttpServletRequest.
