[rules-users] XOR Rules

[Bojan Janisch]

Thanks Steve and Wolfgang, that helped me a lot. Not the salience, but using a blocking fact was very helpful and also using the activation-group. Though I did not found something about it in the book "Drools JBoss Rules 5.0 Developer's Guide". Maybe it is just too basic for the book or I'm not skilled enough to find it, probably the second.  

So anyway thanks you two.

Not explicitly. The usual practise is for each rule to insert a blocking fact and create a condition in each rule, which ensures that it only fires if the blocking fact doesn't exist. If you want one to take priority over the other, then you can use salience.
