Still trying to get this to work. I have managed to create from a default (new) guvnor setup. Steps I do.. 1. Create fresh guvnor 2. In eclipse create Message.java file in package com.sample, and create a jar file 3. In guvnor import the model for the Message.jar file 4. In guvnor create a category 5. Create an import statement for import com.sample.Message 6. Create a simple technical rule, something like when, Message(), then, System.out.println("."); 7. Build the pkg 8. download the pkg use the code from previous post to load the pkg... it works fine.. now, goto guvnor advanced view and change the Configuration from: import com.sample.Message to: import com.sample.Message; declare Message @role( event ) end build the pkg, download the pkg, run the test program... I get: org.drools.RuntimeDroolsException: unable to resolve Type Declaration class 'Message' at org.drools.compiler.PackageBuilder.addPackage(PackageBuilder.java:754) at org.drools.compiler.PackageBuilder.addKnowledgeResource(PackageBuilder.java:515) at org.drools.builder.impl.KnowledgeBuilderImpl.add(KnowledgeBuilderImpl.java:25) at com.sample.DroolsTest.readKnowledgeBase(DroolsTest.java:69) at com.sample.DroolsTest.main(DroolsTest.java:27) richarda wrote: > > So, my code is doing this: > > KnowledgeBaseConfiguration conf = > KnowledgeBaseFactory.newKnowledgeBaseConfiguration(); > conf.setOption(EventProcessingOption.STREAM); > KnowledgeBuilder builder = > KnowledgeBuilderFactory.newKnowledgeBuilder(); > try { > File f = new File("/tmp/my.pkg"); > InputStream stream = new FileInputStream(f); > if (stream == null) { > jlog.fatal("Unable to find rule pkg"); > } else { > jlog.info("adding pkg"); > > builder.add(ResourceFactory.newInputStreamResource(stream), > ResourceType.PKG); > } > } catch (Exception e) { > e.printStackTrace(); > } > KnowledgeBase kbase = > KnowledgeBaseFactory.newKnowledgeBase(conf); > kbase.addKnowledgePackages(builder.getKnowledgePackages()); > jlog.info("setup creating knowledge session"); > ksession = kbase.newStatefulKnowledgeSession(); > jlog.info(" setup ksession created"); > > > The pkg was created from Guvnor. > > If in the package declaration area in Guvnor, (where you put the import > statements) > If I put > declare Signature > @role ( event ) > end > > then build the package, save it to disk /tmp/my.pkg > on startup I get: > > [#|2009-11-24T14:50:38.944+0000|WARNING|sun-appserver2.1|javax.enterprise.system.stream.err|_ThreadID=12;_ThreadName=pool-1-thread-3;_RequestID=7c35064d-757e-4519-b5eb-433db89e168d;|org.drools.RuntimeDroolsException: > unable to resolve Type Declaration class 'Signature' > at > org.drools.compiler.PackageBuilder.addPackage(PackageBuilder.java:754) > at > org.drools.compiler.PackageBuilder.addKnowledgeResource(PackageBuilder.java:515) > at > org.drools.builder.impl.KnowledgeBuilderImpl.add(KnowledgeBuilderImpl.java:25) > > > I need to declare 'Signature' as an 'event' > Am I doing this wrong? > > If I do this all in Eclipse and load the DRL files manually it all works. >

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.

Yeah, its in the classpath.. and to be doubly sure just before the code I do a Message s=new Message(); and that works.. so jvm can find the Message 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.
