How to start the java console when launching an application from Eclipse?

Question

When I start a java application, the Java Console is started. But when I start a java application from Eclipse, the Java Console does not start on its own. How can I make it start also when I run an application from Eclipse?

• Jenny Smith: I need the console, because I need to set the debugging level. And I need to run it from Eclipse, because there are a lot of settings which need to be set (Tomcat, jar, sign jars, etc).

• McDowell: @Jenea - This is not enough if java.io.Console support is required. See bugs.eclipse.org/bugs/show_bug.cgi?id=122429

If you are wanting the program to start in it's own window. Try running it as an external tool. The program would be cmd.exe and the argument would be your java command line, e.g. "java -cp c:\myclasspath myProg" and so forth.

First check that no other console is pinned, icon looks like window with a needle in it. This means that no other console except the one that is pinned will show the output. If everything else fails try to reset the java perspective in Eclipse.
