Eclipse console no output

Issue

I am using Eclipse Juno under Ubuntu 12.04. I have installed CDT and the console works perfectly there. I had some problems compiling some java code from command line - it was related to the fact that there were multiple jdks installed and the system compiled with 1.7 and tried to run with 1.6 -> int produced some error. After I've set the JAVA_HOME to 1.7 and java-alternatives based on this : https://askubuntu.com/questions/121654/how-to-set-default-java-version everything worked out. I haven't noticed until now, that probably this affected Eclipse, since when now I try to run something it doesn't show up in the console, but if I run the binaries from the bin directory directly from the terminal the output is shown in the terminal. After java -version I get the following response:

java version "1.7.0_09"
OpenJDK Runtime Environment (IcedTea7 2.3.3) (7u9-2.3.3-0ubuntu1~12.04.1)
OpenJDK 64-Bit Server VM (build 23.2-b09, mixed mode)

How can I make Eclipse show up the results of the run in the console?

Solution

I installed Aptana3 and it changed the color scheme of eclipse and when I tried to fix it I changed a lot of colors and by mistake I changed the background and the output color both to white, so actually the output was there, just I was not able to see it.
