Adding docs to external jars in eclipse

If you have some external jars, like in my case the GWT libraries and you want to add the handy javadoc to them - its not exactly obvious. You need to navigate on the Package explorer view to the "Referenced Libraries". Unfold this tree, and then right click on the relevant library. Click on properties and then javadoc. Add the directory and click validate just to check. Bingo - now the javadoc will appear using the tooltip in the main editor.

I was playing around with launching the taverna workflow engine programmatically. The answers it spat back out all looked slightly weird.

According to the taverna user group this is cos the answer is encoded in base64. To see how it should look, stick it through mmencode:

mmencode -u name.txt

A somewhat more comprehensable answer should emerge:

Now to find the java libraries to do this in code.
