The ServletSessionPool provides overloaded call() methods for use inside an HTTP servlet. These methods accept their input parameters in terms of an HttpServletRequest object, and therefore can conveniently be passed the same HttpServletRequest object that was passed into your HTTP servlet's doPost() or doGet() methods. However, in this instance, you must ensure that the names of the HTTP posted name=value pairs correspond to those expected by the Tuxedo service. The ordering is not important, because the data is ultimately converted into a Java Hashtable. Other non-related data in the HttpServletRequest will not disrupt the Tuxedo service.

A Tuxedo service is invoked from within an HTTP servlet with the following method:

ssPool.call("serviceName", request);

where ssPool is a reference to a ServletSessionPool, " serviceName " is the name of the Tuxedo service you wish to call, and the request argument is the HttpServletRequest object associated with the servlet.

The ServletSessionPool.call() method internally converts the HttpServletRequest into a ServletDataSet, which can be submitted to a regular SessionPool.
