Expand the “Experiments” node to view the details of the experiment.
If you reached this step that means you have followed the instructions given here carefully and successfully launched a job in Ranger.
So now you might think that you want to run your own application installed on Ranger. In that case you wont be able to use this same XBaya instance (which was started through JNLP) to invoke your application. That is because, this demo uses a community account associated with the OGCE group to submit the jobs to Ranger. Since you have installed your application through your Ranger account, you should configure backend Airavata server to talk to Ranger properly with your XSEDE credentials.
Please refer the blog post to configure your Airavata Server properly to submit jobs to Ranger.
If you run into issues please contact airavata-user mailing list and post your question.
