Wouldn't your passwordSource need to look more like:
passwordSource="java -cp PUT_CLASSPATH_HERE com.lenka.Password"
You need to tell Java where to find your class. For your simple case,
you only need the root directory containing com/lenka/Password.class.
I just made a test case using one of my old models and changed it to
use the executable program option. It worked. Here is what the login
portion of my node XML looks like:
<login userName="techreg" passwordLocation="executable"
passwordSource="java -cp
/Users/mgentry/Documents/workspace/TestLenka/bin com.lenka.Password"/>
mrg
PS. I discovered a bug in doing this. You can't generate your DB
schema from the modeler when using the executable program option.
I'll file a bug report for this.
