I believe the "cmd" and the "executable" are the same thing -- it  
says that in the code if I remember correctly. So, your "cmd" would  
be the main class of your application, for the Java universe [1].

Yes, always use absolute paths otherwise it is difficult to find the  
files you want (or in this case need) to send.

Thanks. I hope you didn't have to make too many changes.

You need to specify all files with an absolute path. The executable  
(TestJob.class) needs to be specified, and all the files that it  
needs, as you mentioned, must as well.

I think the problem you are seeing is coming from sendFileHelper() in  
the SOAPScheddApiHelper.java you sent. In there you will find the  
line "int index = filenameWithPath.lastIndexOf('/');" that will not  
give you a correct response because your paths use '\'s instead of  
'/'s. Try changing the '/' to a '\' and see what happens. This is  
likely a broken assumption that was made in the helper api, sorry.

Are you talking about for the "newAttr" argument, that can definitely  
be null without worry. If you mean somewhere else let me know.

Sorry about the slow response on this, and thanks for mentioning  
Birdbath in the subject!
