How can a properties file be created using Talend Open Studio Data Integration?
<p>I've used Talend Open Integration studio for sometime to just create jobs and run it from the IDE or export it as executable jar file. But I haven't used it extensively. 
Is it possible to create an external configuration file that holds different server names and other variables so that after I create an executable jar file of my Talend job, I can just change configuration text file and select different database servers or port options?</p>

<p>I also used MuleSoft for a little bit, so if anyone knows how to do this with MuleSoft any advise would be kindly appreciated. </p>
