Hi @BNK ,
I agree with @vlad.coteanu - this has worked for me in the past while working with Java applications:
On each selector - open in UI explorer and navigate through the hierarchy on the left side of the screen:
This will help you identify more elements than just the basic selector can.
Another possible solution would be to use Anchor base activity (https://docs.uipath.com/activities/docs/anchor-base) if you can identify some stable elements next to elements that you want to interact with.
Also make sure you install the Java bridge (Studio should detect that you are trying to automate Java and suggest this automatically). LATER EDIT: not valid suggestion, because Java bridge is part of the Java extension which is not used for Jawa SWT applications (see first comment from @vlad.coteanu )
