Executing runExamples.sh on OSX
by NickD
Hello all,
Newbie question here, but I wasn't sure from the manual if the issue was
mine or related to OS X.
I am trying to run the drools-planner examples in
src/main/assembly/scripts/runExamples.sh, but continue to get this error
nomatter what example I try. Am I missing something simple?
% ./runExamples.sh
./runExamples.sh: line 3:
lib/drools-planner-examples-${project.version}.jar: bad substitution
The environment is OSX Snow Leopard with Drools compiled from latest source
(5.1) in the last week as per the Planner manual. JAVA_HOME, etc is defined.
Any suggestions are very welcome.
Cheers, Nick

String as an argument
by Khalil Hafsi
Hi Guys,
I am using Drools fusion 5, My "Event" class // @role (event) // has a
string parameter "id" , however if I try to do :
//
Rule ..
..
$a : Event(id == "a")
then
//do something
end
It complains about "Conversion from double is not supported in
java.lang.String" , is there any way to make it accept String arguments ?
Thanks,
K.H-

Re: [rules-users] RES: Problem with proxy objects
by Edson Tirelli
Rogerio,
I don't know what javassist does with your class... if it preserves the
object hierarchy (what I think it probably does), then it must work. The
only way to find out the reason is with an isolated test case and do some
debugging to understand why it is not failing the isAssignableFrom() tests.

Perhaps. But the code you posted doesn't seem right.

In any case, your rules must reference the classes of the objects you
insert, or a superclasse, or an implemented interface. Otherwise, no
rule will fire.

Problem with proxy objects
by Rogerio Baldini
Hi guys,
I am trying to execute rules passing a proxy object to it.
The object myObject is a javassist proxy object:
package.MyClass_$$_javassist_2
Properties p = new Properties();
p.put("url",
"http://localhost:8090/drools-guvnor/org.drools.guvnor.Guvnor/package/pacote
/LATEST");
RuleAgent agent = RuleAgent.newRuleAgent(p);
RuleBase ruleBase = agent.getRuleBase();
StatelessSession ksession = ruleBase.newStatelessSession();
ksession.execute(new Object[] {myObject});
So, with this proxy object, my rule is not executed. If I pass a real
instance, the rule works fine.
package mypackage;
import package.MyClass;
global java.util.List list
rule "Testing"
dialect "java"
when
f: MyClass()
then
System.out.println("Exist "+f.getDay());
f.setDay("15");
end
Can anybody help me ?
Thanks,
Rogerio
