I'm running CR1 (Guvnor and exec server) on Tomcat (tried v 5XX and 6XX)
I've tried this with the mortgage package and then went simpler, I'm
getting the same error.
The package now has one rule:
when
eval(true)
then
System.out.println("It works");
Compiles fine on govner, etc.
My rule agent configuration is:
newInstance=true
#file=/foo/bar/boo.pkg /foo/bar/boo2.pkg
#dir=/my/dir
url=http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/foo/test
#localCacheDir=/foo/bar/cache
poll=30
name=MyConfig
When I post to the url (via poster in firefox) I get:
