I installed oracle weblogic server 10.3.6 and set up my data-source successfully but when I opened eclipse and added the server it always gives the error in the screenshot-1…from this point I tried removing the data-source and enter it again it always fails to connect in the test configuration step as screenshot-2 although the db credentials are correct…could anyone help ?

eclipse-error:
