java.io.Console support in Eclipse IDE

Eclipse run the program on a background process, rather than a top-level process with the console window we're familiar with. Is there a way to force Eclipse to run the program as a top level process, or at least create a Console that the JVM will recognize? Otherwise, I'm forced to jar the project up and run on a command-line
