CICS Transaction Gateway V5 The WebSphere ... - IBM Redbooks

create a record for use
jsr = new JavaStringRecord(encoding);
// set input data if we have any
if (commareaLength > 0)
{
jsr.setText(commarea);
}
// make the call
try
{
eciInt.execute(eSpec, jsr, jsr);
}
catch (ResourceException e)
{
// output the stacktrace and re-throw it back to the client
e.printStackTrace();
dropConnection();
throw e;
}
Figure B-36 Executing an ECI request
We create a JavaStringRecord object to encapsulate the COMMAREA data,
both input and output, and set our input data. We then use the Interaction we
got from the connection factory to execute the request by calling its execute()
method. We pass the ECIInteractionSpec object eSpec, and the
JavaStringRecord object jsr as input and output. If an exception occurs in the
Interaction execute() method, we catch it, print the stack trace to the
application server, drop our CICS connection, and rethrow the exception back to
the remote client.
Finally, we close our CICS connection, and create and set our response
ResultsBean object, as shown in Figure B-37. We use the text and the byte array
from the JavaStringRecord and return the ResultsBean.
dropConnection();
// return the commarea from the last executed program
ResultsBean resultsB = new ResultsBean();
resultsB.setResultsString(jsr.getText());
resultsB.setResultsBytes(jsr.getData());
return resultsB;
