I am curious how you want to use Talend to manage AnaplanConnect, as the BI Team in my organization uses Talend for our ETL processes and I manage job schedules through the portal. However, I am not using Talend directly with AnaplanConnect. Instead, I have a different scheduler tool that kicks off the AnaplanConnect batch scripts for imports and export in Anaplan, and then stages files for Talend to pick up and process back to our data warehouse. Are you attempting to use Talend as a scheduler to run AnaplanConnect batch scripts?
The way I set up our implementation, the AnaplanConnect installation is housed on a server with Java installed along with my keystore. The scheduler calls the AnaplanConnect batch files that I wrote, which run on the server and use the key in my keystore to authenticate to Anaplan and run the actions specified in the batch files.
I think you'll need to write your AnaplanConnect batch scripts and make sure they function properly when run from the server with your installation and keystore. Then, you may be able to call the batch files via a Talend schedule. But, you would call the batch files you write, not the .jar file you mention. The .jar file is used by the "AnaplanClient.bat" (or "AnaplanClient.sh if you're using linux). The "AnaplanClient.bat" file is used by the batch scripts you write to execute actions within your models.
Did you see the batch file examples in the installation directory related to using a java keystore? I think they would help you a lot. Once you get a batch file with the keystore certificate authentication process working properly, you should be able call the batch file using Talend scheduler.
I'm sorry, I am not a Java developer -- I wrote our AnaplanConnect processes with Windows Batch files. Here's an example that was provided to me when I first implemented our CA certificate.... something that I have just started looking at again, because our CA cert will be expiring soon. This batch file should be run from the same directory where the AnaplanClient.bat file is located (see the line starting "set Command=.\AnaplanClient.bat" which calls the AnaplanConnect client, indicates the client is in the same directory as the batch file that calls it).
The information in my previous post gives you that. Truly, you should review all the information in the links I provided and download a full copy of the AnaplanConnect package. It seems likely that you are trying to work with only a partial package and without reading all of the documentation.
