Re: [rules-users] unable to resolve Type Declaration class

Yeah, its in the classpath.. and to be doubly sure just before the code I do a Signature s=new Signature(); and that works.. so jvm can find the Signature object. I have created https://jira.jboss.org/jira/browse/JBRULES-2348 I would love to know if any workarounds are possible, this has ground my project to a halt. thanks Ric Edson Tirelli-4 wrote: > Kris just reminded me of something: do you have the actual Message > class > in the test program classpath? > > When downloading the package from guvnor, I think it does not download > the model jar... only the actual rules, etc... > > Edson > > 2009/11/25 richarda <richard.ambridge(a)gmail.com&gt; > >> Also tried under 5.1.0M1 release.. same issue :( >> Am i doing something wrong by declaring the @role in the Configuration >> section? >> >> >> richarda wrote: >>> Still trying to get this to work. >>> I have managed to create from a default (new) guvnor setup. >>> >>> Steps I do.. >>> 1.
