[rules-users] not able to debug drools flow

[Maximiliano Batelli]

Hello
I have the same problem when debuging rules using eclipse 3.5, drools 5.0 and jdk 1.6.
I downgraded to eclipse 3.4 and worked for me.
Is there a solution to let me debug using eclipse 3.5?

Thanks
Max




Hi,

I`m experiencing the same problems as Vishal. I am using Eclipse 3.5
and newest Drools. I am only able to debug project as Java
application, but when I want to debug it as Drools application all I
get is this problem. I also tried disabling firewall and changing its
settings but as it seems it does not help.
So if anyone has figured out a solution to this problem, I would
really appreciate an answer.

Thanks,
Jakob

probably related to your personal firewall:

I don't think this is a Drools specific issue.
