Displaying Java Plug-in Error Messages

You enable the Show Java Console option on the Java Plug-in Console (see "Basic Tab") to view error messages generated by Java Plug-in. When you visit a Java Plug-in-enabled page and encounter an error, the Java Plug-in Console opens, showing the error output. All output written to the Java System.err or System.out streams is written to the Console window.
