Retrieving a Cognos report
Retrieving a Cognos report may require a while loop construct invoking report retrieval, as a connection to the server may time out before the report is sent. An example using a short running business process is provided.
Invoking a get function to retrieve a Cognos report could fail due to a time out condition at run time. Therefore look at the session value, which is enumerated so you can evaluate the valid values, to determine if you should try invoking again in a while loop construct. The session needs to be mapped from the response to the request of the next invocation.
The Java code snippet in the while loop is as follows:
if (GetCognosReportResponse != null) {
if (GetCognosReportResponse.getDataObject("session") != null) {
return !GetCognosReportResponse.getDataObject("session").getString("status").equals("complete");
} }
return true;
Mapping the response to the request is shown in the ResetSession assign activity as follows:
Add the cleanHeader method at the end of your process, as discussed earlier in the sections on the handlers, as it frees up thread storage and allows a thread to be reused. Select a Java snippet activity from the palette and add it to the end of the business process. Select the Properties view for the Java snippet and then the Details tab. Add the code to the pane provided.
