                         boolean importAny)

Creates the object to store the data set. This method is for internal use only.

Parameters:

initCapacity - Initial capacity

importAny - true to import any data; false for input parameters only

Method Detail

importRequest

public void importRequest(javax.servlet.http.HttpServletRequest request)

Imports the HTML field names and corresponding values from a javax.servlet.http.HttpServletRequest object. This method is useful when the data from the HttpServletRequest is insufficient for directly calling a BEA TUXEDO service. The data should be imported into a ServletDataSet where additional parameter data can be specified.

The following sample code adds a parameter named "REQUEST_TIME" to the parameters imported from request before calling the BEA TUXEDO service "DEBIT". This code would typically be in a servlet's doPost or doGet method.

 ServletDataSet dataset = new ServletDataSet();
 
 // Import the HTML form fields from the HttpServletRequest
 dataset.importRequest(request);
 	
 // Add the REQUEST_TIME parameter to the input data set
 dataset.setValue("REQUEST_TIME", (new Date()).toString());  
 
 // ... Insert code to get the servlet session pool
 
 // Call the DEBIT service using the combined input data
 session_pool.call ("DEBIT", dataset, null); 
 

Parameters:

request - HttpServletReques object
