Implicit Context Load with dynamic context file path

Anonymous — Mon, 03 Dec 2018 11:28:09 GMT

We have requirement where we need to read context parameter values from the config file.However config file path should be passed dynamically while calling graph from server.

Thus whatever path is passed system should read context file from that path only.

How can we achieve this in talend.

The solution I describe here (https://community.talend.com/t5/Design-and-Development/multiple-implicit-context-loads-from-multiple-files/m-p/142960#M88267) should work for you

The trick here is that you can use Java methods (routines) in the Implicit Context Load parameters. As such, they do not need to be hardcoded. So you can write a Java class to handle selecting your appropriate context file and simply add the methods that pick the correct paths, etc, to your implicit context load params.

Click on File, then Edit project properties. From the dialogue box, expand Job Settings and select the option for Implicit context load. Check the option for Implicit tContextLoad. Check the option From File. Set the From File name to iTunes Login.
