Yes, the Java editor in Domino is really bad.  So I do all of my development in eclipse, and have worked with the beta version of Domiclipse.  This tip has nothing to do with either, but with the Java editor in Domino.

Well I lied about doing ‘all’ of my development in eclipse because, when I need to do a quick change I make it in Designer.  Which leads to my biggest frustration about the Java editor in Designer. Not seeing all of the methods available for a given class, or the class not showing at all.  The problem is the editor is treating some text as a string, the compiler is handling it correctly because the code compiles and runs correct.  It is not all strings just the ones with \" in it.  Yes, that simple, and the fix is just as simple.  All I do is place // \" at the end of the line.

So if you have any Java that you import into Domino then please make sure that there is an even number of // \" on every line of your Java code!
