ResultsBean resultsB = tester.execute(funcName, encoding, commareaInput,
commareaLengthInt, username, password, managedBool, gatewayURL,
gatewayDaemonPort, cicsServer, mirror, traceInt, iterationsInt,
appTraceBool);
String results = resultsB.getResultsString();
// set result string attribute
request.setAttribute(attrResultsString, results);
// get byte data from results
byte[] data = resultsB.getResultsBytes();
// set result string in default encoding attribute
request.setAttribute(attrDefaultResultsString, new String(data));
// set request attribute for hex data
request.setAttribute(attrHexResultsString, byteArrayToHex(data));
Figure B-26 Executing the session bean business logic
The execute() method takes all of the HTML form parameters as input and
returns a ResultsBean object. This is a data bean class that encapsulates a
String object and a byte array, and provides methods to get and set both. It is
shown in Figure B-27 on page 365.
If the session bean does not successfully complete the CICS request, then it will
throw an exception, so the execute() method call is inside a try catch block.
Assuming the execute() method ran successfully, we set a request attribute for
the COMMAREA converted into a String in the encoding specified in the HTML
form. We also set an attribute with the hexadecimal representation of the
COMMAREA, to aid data conversion debugging, and an attribute with the
COMMAREA converted into a String using the JVM default encoding.
