Well, it was more the fact that they weren't really necessary since I could 
just edit the beanshell. That is, in 1.7, there seemed to be an advantage to 
using the builtin Java processors but in 2.1 they're the same as beanshell, and 
one custom bit of beanshell is a lot simpler than 2 string constants and a 
processor.

I'll have to pull out the passwords, but I can do that. Or let me try the 2.1 
release first and see if it's still a problem. 


The SQL null handling remains a bit of an issue. SQL tables not infrequently 
have NULLs that ought to get passed to Taverna (and vice versa, from Taverna to 
the database). My hack of making a NULL into the string "null" is, well, a 
hack. I hope there's a better solution eventually.
