Invoking the Talend Administration Center API programmatically
Once the JSON arguments are base-64 encoded, they can be passed as the sole
parameter to the HTTP request. If you are integrating with Talend, your application might be written in regular
Java, or possibly some other language, which should not cause any issues since the HTTP
and base-64 are interoperable standards.
Before you begin
To invoke the Talend Administration Center API, the JSON objects must be base-64 encoded.
Procedure
-
If you are using Talend, use the
tLibraryLoad component to add the Apache Commons
library.
You can retrieve the MetaServlet Job archive attached to the Downloads tab on the left panel of this page to invoke the Talend Administration Center API from the Talend Job.
It uses the encodeBase64() method within a tMap prior to the tRESTclient invocation of the Talend Administration Center API operations. Three operations are invoked, and each operation is invoked within its own SubJob. Each SubJob starts by initializing the request from the Context Parameters:- The first invocation looks up the taskId based on the human readable Job name.
- The second invocation uses the taskId returned from the first invocation to trigger the Job.
- The third invocation uses the returned execRequestId handle as the argument to the getTaskExecutionStatus operation to monitor the Job status.
