Selecting the service to Trigger and setting the service parameters

After defining the business entity on which you want to trigger a specific Process, you need to select a service to run on the defined business entity and set the service parameters.

About this task

To select a service to trigger and set the parameters, do the following:

Procedure

  1. In the Service area, click the Service JNDI Name arrow and select from the list the service you want to kick off by the Trigger, callprocess in this example.
    Information noteNote: The services you can find in the list are pre configured MDM services. Click the button to open a dialog box that gives information about what the service does and its parameters.
  2. In the Service Parameters area, define the parameters of the service you select in the list.
    When you select the callprocess service, you just need to click the name of the Process you want to trigger, Call_Job in this example. For more information about how to create a Process from scratch, see Creating a Process from scratch.

Results

The callprocess service is one of the most important available services on the list. When you select this service, all Processes you already created in Talend Studio are listed in the Service Parameters area and you can call any of them to transform and cross-reference master data.

The parameters you need to define in the Service Parameters area differ according to the selected service in the service list. Talend Studio simplifies this task for you by creating the underlying XML code for the proper execution of the trigger.

When you select the callJob service, for example, you can access a list of all deployed Jobs directly from the Trigger editor.

When you select the workflowcontext service, for example, you can access a list of all deployed workflows directly from the Trigger editor and this simplifies the process of creating a Trigger.

In the Service Parameters area, you can specify the Workflow process version number and the user name and password for accessing the BPM server. The specified credentials here will override the default settings for the Bonita technical users in the file <$INSTALLDIR>\conf\mdm.conf where <$INSTALLDIR> specifies the path where the MDM server has been installed.

Information noteNote: For certain services, you can switch between a graphical editor and a text editor upon clicking the Sheet and Source tabs respectively. You can define the service parameters in either editors and any modifications you do in one of the two editors will be reflected in the other.
