I am using Eclipse Version: Helios Release for a java application. I need to run multiple instances of same application and want easy visibility of multiple consoles. can it be done? If yes, how? Thanks in advance.
Just look for your console view and in the right top click on the 'Open Console' button and select 'New console view'
Run the application twice (say instance A and B). Console will display message from B. Then create two consoles as rsilva pointed (say 1 and 2). Both consoles will show message from B. After that change console 1 to display message from A by selecting the arrow near icon with monitor and select the instance A. The message from instance A will be displayed on console 1.
You can of course drag (or detached) one console to other place for better visibility.
If you write out your console information to multiple logs, then you can use a utility called Baretail which is highly configurable and easy to use. It allows you to view a growing file, i.e. logs for example, in realtime. Its easy to use and highly configurable - might be of some help to you.
