Hi ,
I Build few classes using Eclipse and then import it into "JBoss BRMS"
then I created few rule and and using "knowledge base" I created binary
package.
I try to open the pkg using Eclipse with this code :
Collection<KnowledgePackage> kpkgs = new ArrayList<KnowledgePackage>();
ObjectInputStream in = new ObjectInputStream(new FileInputStream(
"c:/com.jspeed.brms.fire.pkg"));
Object o = in.readObject();
System.out.println("Read: pkg ok ");
in.close();
KnowledgePackage kp = (KnowledgePackage) o;
kpkgs.add(kp);
KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase();
kbase.addKnowledgePackages(kpkgs);
and I am getting error -
java.io.ObjectInputStream cannot be cast to
org.drools.common.DroolsObjectInput
What am I doing wrong ?
My imports :
import java.io.FileInputStream;
import java.io.ObjectInputStream;
import java.util.ArrayList;
import java.util.Collection;
import java.util.HashMap;
import java.util.Map;
import org.drools.KnowledgeBase;
import org.drools.KnowledgeBaseFactory;
import org.drools.definition.KnowledgePackage;
import org.drools.runtime.StatefulKnowledgeSession;
import org.drools.runtime.rule.FactHandle;

I'm not sure how this .pkg file was created, but if I guess correctly,
you should be able
to add it to a KnowledgeBuilder:
kbuilder.add( ResourceFactory.newFileResource( "...pkg" ),
ResourceType.PKG );

Probably the Drools Runtime configured in Eclipse is not same version as
what is used in your Guvnor. Make sure that you are using the same bits
on both sides and try again.

ok ,
You are right, I created the pkg file using Eclipse and everything works
fine.
Then I reconfigured my Eclipse to the
BRMS(Window->preferences->Drools->Installed Drools runtime)
I deleted the current run time and link it from the beginning to the
runtime.
But I'm still having the same problem.
am I missing something ?

Sorry I don't understand >> I deleted the current run time and link it

Earlier you said you are using JBoss BRMS so seems like the supported
bits you downloaded from the RHT customer support portal.
In this case your download should contain two zips, jboss-brms-manager
(guvnor) and jboss-brms-engine (core engine).
When you create your Drools runtime in Eclipse, you should first unzip
jboss-brms-engine into a directory, then point your runtime to that
directory.
Hope this helps

ok,
I think I'm missing the second zip file,
my computer contains only one zip file - brms-standalone-5.1.0.zip
So I probbly need to send email to RHT and ask for the second zip,
as for now my runtime is (brms-standalone-5.1.0) .
Thanks for your Help

Michael Biniashvili,
8:09 p.m.
Look at the BRMS download section in the Customer Support Portal. It
contains "JBoss BRMS 5.1.0 Standalone" which apparently you got. This
contains both guvnor and the engine together deployed in the Guvnor web
application. On the same download page you should also see "JBoss BRMS
5.1.0" which contains the two zips I was talking about.
Hope this helps.
Thanks.
