How to store the rules data into RDBMS, like mysql, oracle
by Sinboy Zhang
Hi,all:
Guvnor is a BRMS,it can manage the rules through Jackrabbit
Repository.The default,Guvnor work well with derby database.But i want it
work with my database,just like MySQL.
My step is :
1.Run Guvnor with default,and generate the repository.xml and repository
dictionary at JBOSS_HOME\bin dictionary
2.delete repository dictionary and edit repository.xml,only replace the
content in <PersistenceManage> label ,just like this:
<PersistenceManager
class="org.apache.jackrabbit.core.state.db.SimpleDbPersistenceManager">
<param name="driver" value="com.mysql.jdbc.Driver"/>
<param name="url" value="jdbc:mysql://localhost:3306/guvnor_db"/>
<param name="user" value="root" />
<param name="password" value="a123456" />
<param name="schema" value="mysql"/>
<param name="schemaObjectPrefix" value="${wsp.name}_"/>
<param name="externalBLOBs" value="false"/>
</PersistenceManager>
3.install Mysql database,and create the guvnor_db database instance,and
copy mysql driver to JBOSS_HOME\server\deploy\lib
4.Restart the JBoss ,i get the exception:
org.drools.repository.RulesRepositoryException:
javax.jcr.RepositoryException: Invalid repository configuration:
repository.xml: Replacement not found for ${wsp.name}.: Replacement not
found for ${wsp.name}.
Why?Please help me,thanks!

BaseMinaClient - Session Termination
by mardo
Hello,
I have a simple RuleFlow containing a Human Task, which I start using the
following lines of code:
WSHumanTaskHandler wsh = new WSHumanTaskHandler();
ksession.getWorkItemManager().registerWorkItemHandler("Human Task", wsh);
ksession.startProcess("com.sample.ruleflow");
When the workflow has properly ended however, there remain threads (e.g.
NioProcessor&NioSocketConnector) within the VM. I have tracked this down to
BaseMinaClient:
public void disconnect() {
if ( session!= null && session.isConnected() ) {
session.close();
session.getCloseFuture().join();
}
}
Expllicitly calling wsh.dispose(), session.isConnected() (from IoSession)
always yields true even when the workflow instance has terminated already
and there are no more active human tasks available.
Is this an intended behaviour?
Thanks and best

Drools with Web Application
by Sahid Khan (সাহিদ)
Hello,
Drools is very new to me. So please excuse me if this question sounds too naive.
Basically my requirement is: I have a web based (3-tier j2ee)
application which is
deployed in JBoss AS. Now I want to incorporate some business rule
implementations with this application so that end users, who are not
very technical, can add/modify the rules according to their need. I
suppose Drools Guvnor will be the front end and rules repository and
Drools Expert will be
the back end for such requirements. Please correct me if I am wrong.
I had gone through the drools documentation. That talks about
stand-alone application for guvnor itself, but I want to use Guvnor
inside my existing application itself, preferably by using some Guvnor API.
Can some one please provide some insight on how to do this. Also, I'll
appreciate if some one can point me to some getting started/best
practice documents for these stuffs?
Many thanks in advance,

Import and Export at Package level
by krishna.cj
Hi,
We are running Guvnor on two machines, out of which one is used for
developing and testing rules, say test environment, and another is
used for providing rules for production application. Our test
environment typically contains more than one package and each in turn
contains multiple snapshots. When we use Export and Import to
provide updated rules to production environment, all the packages and
snapshots are imported to the production environment.
Is there any way to use Export and Import at package level so that we
can export only the package we want and no other package or snapshot?
Any help would be a great help to us..
Best Regards,
Chaitanya.
