C-768 Use the Connect-Java method to call a public method of an external Java class, using a Rule-Connect-Java rule.
This method operates on a named clipboard page that is the source and destination of data mappings. Make sure the Step Page column that calls this method contains the non-blank name of such a page. B-3575

Parameter |
Description |
ServiceName |
Enter the Service Name (second key part) of a Connect Java rule, an instance of the Rule-Connect-Java rule type. The system uses the class of the step page as the first key part. |
RunInParallel |
Select if this connector is intended to run in parallel as a child requestor of the current requestor. If selected, use the Connect-Wait method later in the current or a follow-on activity to access results from the connector. |
The Connect-Java method works as follows:
This method updates the pxMethodStatus property. See How to test method results using a transition.
Design the activity to detect and handle exceptions. If the Connect-Java method with the RunInParallel checkbox selected fails in a way that causes the Connect-Wait method to be skipped, the child requestor can be left hanging. If the limit of parallel requestors is then eventually reached, the parent requestor will fail as well. B-20430 TANDP By default, the limit is 10 requestors in parallel; you can establish a higher or lower value in the prconfig.xml
file or Dynamic System Settings using the services/maxRequestorChildren
setting.
B-11491 This method cannot be used in a step that involves iteration.
