I have created an java Application in Eclipse IDE. Can anyone help out how to edit a Java application in Eclipse & trigger a deploy to Bluemix.
The official IBM Bluemix plugin for Eclipse can do this for you.
Grab it from the Eclipse Marketplace here: http://marketplace.eclipse.org/content/ibm-eclipse-tools-bluemix#.VHAf-1Xd9E4
Here is some documentation about the plugin: https://developer.ibm.com/wasdev/downloads/#asset/tools-IBM_Eclipse_Tools_for_Bluemix
Once you install this, you should be able to connect your Bluemix account and package / deploy apps with the push of a button.
