Deploying Guvnor on a existing repository DB
by maav
Hi!
I'm trying to get Guvnor to deploy on a pre-existing existing DB. The use
case beeing that we wan't to be able to bring up a backup instance of guvnor
in case the primary goes down.
But if a deploy guvnor on a "fresh" DB schema all tables get created along
with trigger and sequences (using Oracle 11).
But when I un-deploy guvnor.war and remove the repository-folder and then
deploy it again I get the following exception:
Caused by: java.sql.SQLException: ORA-00001: unique constraint

Drools flow persistence with Oracle, Could not obtain BTM transaction manager instance
by loumimi
Hello,
I crated a sample application to test the persistent of drools workflow. I
tried the example given in the documentation using H2 Db, everything works
fine.
But when I tried to move to Oracle, I have several problems. I resolved the
bug related to entity names when they are longer than 30, but I still have
an other problem with BitronixTransactionManager
Can you please check if I'm missing some things ?
Here's my stack trace

Question / problem
by Nico ROEDERER
Hi,
I've got a little question. I've got a drl file which contains two rules :
rule "FirstRule"
salience 99
when
$testDrools : TestDroolsDto()
eval ( 1 == 1 )
then
System.out.println("Set my value to 1");
$testDrools.setMyValue("1");
end
rule "SecondRule"
salience 1
when
$testDrools : TestDroolsDto()
eval( $testDrools.getMyValue().equals("") )
then
System.out.println("My Value : " + $testDrools.getMyValue() );
end
Is it normal that in my second rule is verified ?
-> eval( $testDrools.getMyValue().equals("") ) is true
but : System.out.println("My Value : " + $testDrools.getMyValue() );
show me that myValue == 1
Perhaps I did something wrong ?
Thanks for your helping me.
N.
PS : Here is me TestDroolsDto :
public class TestDroolsDto {
private String myValue;
public TestDroolsDto() {
myValue="";
}
public String toString() {
return " --> " + myValue;
}
/**
* @return the myValue
*/
public String getMyValue() {
if ( myValue == null ) {
myValue = "";
}
return myValue;
}
/**
* @param myValue the myValue to set
*/
public void setMyValue( String myValue ) {
this.myValue = myValue;
}
}

Re: [rules-users] Question / problem
by Bruno Freudensprung
You are right; your probably need to set a no-loop atttribute on your rule.
Or, preferably, put additional conditions to the LHS of your FirstRule
(it would probably be the case in a "real-life" rule).
As Wolfgang suggested, take some time to read Drools expert
documentation: I found it very well designed for beginners (like me).
Regards,
Bruno.

Test:

private String stringField;
public Integer getIntField() {

public void setIntField(Integer intField) {
this.intField = intField;
}

}
My input Fact:
--------------
Test myObj = new Test();
myObj.setIntField(0);
When I use the following things work fine. I can see all output messages in
order.
final StatefulKnowledgeSession ksession = kb.newStatefulKnowledgeSession();
//Where kb is the knowledgebase built using the above assets
Output Messages:
-----------------
Done with rule 13 12345
here
12345

When I use the following it exits without any errors, but, output messages
are not as expected!
final StatefulKnowledgeSession ksession =
JPAKnowledgeService.newStatefulKnowledgeSession(kb, null, env);
Output Messages:
-------------------
Done with rule 13 12345
I am exhausted trying to figure out what is going wrong... Don't know where
to debug! Let me know if more information is needed. I am using Hibernate,
Spring, BTM transaction Manager.
I stumbled across "JBRULES-2718" and thought maybe this is something
similar? I am using 5.1.0
Thank you!

Guvnor service to compile part of a package ?
by Vincent Legendre
Hi all,
I am looking for a clever way to compile only parts of a Guvnor package
according to some criteria on items (categories, metadata ...), but
outside Guvnor if possible.
The main idea starts by the fact that it is a little bit complex for a
business user to manage packages and compilations, and even more if he
has to manage conditional compilations (using selectors) of a single
package to produce multiple KB compiled according to business criterions.
I want to compile automatically some KB according to categories (more
generally asset's fields) with something external to Guvnor. Thus I need
a way to query Guvnor repository with criterion to get either :
- the corresponding ressources (DRL)
- the filtered compiled KB (PKG ressource)
Filtering with DRL (like custom selectors in Guvnor) will be perfect,
using a custom class too.
Is there such service ?
Does the KnowledgeAgent allow filtering (did not see anything in docs) ?
Or do I need to add a new service in Guvnor war directly ?
Thanks!
