Guvnor help!
by Adrian Bell
Hi guys,
My apologies if I have sent this to the wrong mailing-list (again)!
I'm very new to Guvnor and Drools and all these exciting tools. I'm
working my way through the example that I found here:
http://www.jboss.org/feeds/post/jboss_drools_how_to_tuning_guvnor_part_1
and everything was just fine and dandy until I had to run the java code!
Unfortunately, I get the following output:
RuleAgent(default) INFO (Tue Feb 24 17:20:57 GMT 2009): Configuring with
newInstance=false, secondsToRefresh=-1
RuleAgent(default) INFO (Tue Feb 24 17:20:57 GMT 2009): Configuring

ewPackage/LATEST

com.ioko.Driver
I've had a dig around the source and can see that the problem occurs at
the point the package is being read. This makes me wonder if the
package I generated from Guvnor is not correct in some way. If I point
a browser at the url, I get the 'opening file' dialog from the browser,
asking me to save the file.
I'm really lost right now. It seems that Guvnor is a pretty good
product and would be a good fit.
Can any of you guys please please please help a newbie?
Many thanks,
Adrian M Bell
