For more advanced users it is quite simple to restore the more usual Java behaviour. From the menu chooser View, Preferences, and click on the "Java, Compiler" item in the preferences tree, then turn off the "Redirect output to:" option. This will restore the Java compiler's default behaviour.
note JAS-150@BUGS prevents this option working when using the built-in compiler. The option does appear to work correctly when an external compiler has been selected.
Once you have done this then you will probably also have to set JAS3's buillt-in CLASSPATH This is also done from the preferences dialog, using the "Java, Classpath" option. You will need to set Classpath to include all the directories from which you want JAS3 to load classes. (More accurately if your .java code contains a package statement, putting your code into a package other than the default directory, you will need to put the directory representing the root of your package heirarchy into the CLASSPATH).
