Being from a LotusScript background i really like being able to see all of the code from my script library in one long searchable block.
I get very frustrated with Java script libraries when I know a keyword I have searched for is in there somewhere but I am forced to navigate though each class within a script library to find it.
If you are using source control you can see all of the script library as a single file within the ODP. This then allows you to search for keywords and backtrack up the text file to see which library the code you want was in.
I use Notepad ++ which is free and excellent. Notepad++ will also reload the ODP file as it is changed in DDE.
The other trick with Java is that once you are back in the editor you can press f2 and then click from a reference to a class through to that class
If anyone has a better way of navigating Java please let me know – it seems so awkward.
