Re: [eclipse-clp-users] Java error messages

Hello Gregory,

In my experience of using the Java interface you can get no more information 
than "there was an error". However, the error usually indicates that ECLiPSe 
is unhappy with the goal you sent it and tells you so; except as far as I am 
aware the Java interface swallows the message. What you could do is to put 
traditional print statements into the code you sent to ECLiPSe and see how 
far it gets. You may have to stick this info to a file as you may not be 
able to see anything that goes to stdout. If you are using the Saros plugin 
for Eclipse IDE you may be able to see your debug info and also more 
importantly the actual error ECLiPSe is reporting.

You can also of course get debug directly into the java interface source. 
But I haven't got very far in bug tracking this way.

I hope this helps,
Paul.
