[rules-users] RuleAgent in webservice
Hi All, I am using drools API, and developed a webservice out of it. I created rule binary package using BRMS Guvnor. I used RuleAgent to acces the properties file. ie RuleAgent agent = RuleAgent.newRuleAgent(/ application.properties); application.properties file was stored in current working directory. I executed my application using eclipse, it was fine . For testing purpose i deployed the application in tomcat application server. Now it is unable to find application.properties file. and shows following in catalina.out file: java.lang.NullPointerException at java.util.Properties$LineReader.readLine(Properties.java:418) at java.util.Properties.load0(Properties.java:337) at java.util.Properties.load(Properties.java:325) at org.drools.agent.RuleAgent.loadFromProperties(RuleAgent.java:299) at org.drools.agent.RuleAgent.newRuleAgent(RuleAgent.java:256) My question is, in which location should i keep the application.properties file , so that RuleAgent can access it.

Re: [rules-users] rules problem
Hi , you can add the following line to the RHS of your rules: drools.getRule().getName() This returns the name of the rule. Note: As the RHS is executed only when the conditions in the LHS are met (satisfied), you can get the name(s) of the rule(s) that are fired.

Re: [rules-users] rules problem
Hi,
if you have a POJO say PersonDetails as:
public class PersonDetails {
String name;
String age;
String sex;
String desg;
public String getDesg() {
return desg;
}
public void setDesg(String desg) {
this.desg = desg;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getAge() {
return age;
}
public void setAge(String age) {
this.age = age;
}
public String getSex() {
return sex;
}
public void setSex(String sex) {
this.sex = sex;
}
}
Then in the rule file you should write as:
rule rule1
when
objectPerson : PersonDetails ( conditions are placed here )
then
rhs
end
So, objectP2483 is the object of your Fact (POJO).

[rules-users] Flow - handling multiple events of the same kind
If the same event-node is triggered twice with different data, the same variable will be recycled for the different data payloads. How does one ensure that data is not lost? My best guess is to follow the event node with a composite node, and copy the top-level variables into the composite's variable scope in the first sub-node of the composite. But I'm not sure whether I can guarantee that the composite will be able to do that before the engine handles the second event. Suggestions? -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/Flow-handling-multiple-events-of-the-same-kind-tp767773p767773.html Sent from the Drools - User mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

[rules-users] Good To Have: TaskClient Interface
There is MinaTaskClient and BaseTaskClient, but no TaskClient interface.

I think it would make sense to create an interface defining the contract, and program to that interface. Am I missing something? Thank you, /Anatoly P.S. I know the whole approach is going to change to be pluggable in the near future, but I find it strange there is no contract/interface that defines a task lifecycle. -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/Good-To-Have-TaskClient-Interface-tp768836p768836.html Sent from the Drools - User mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
Re: [rules-users] Good To Have: TaskClient Interface
wait for two weeks and you will see it there in the trunk! at that point feedback will be appreciated! Probably the task client interface should provide less methods, some basic ones and then we can have a WSHTClient Interface to support all the methods from the spec.

Re: [rules-users] Drools + ETL Process
Hi man, you are mixing a lot of stuff here.. I will recommend you the following steps for achieving the steps that you are mentioning 1) Install guvnor 2) author the rules inside it.. (it already contains a JCR repository, that is similar to a database, it will allow you to store rules there), you can also author some objects (fact model) inside guvnor. 3) Then you can create tests to execute the rules and see which rules are fired.

I am setting up a very simple example using a DSL and Guvnor. My DSL is
as follows:
[when]Age is less than {age} years old=AgeFact(ageInYears {age})
When I attempt to create a new Business Rule using the Guvnor I can select
the above expression just fine and the sentence displays as expected. I
then fill in the years with a numeric value (4) and validate. Upon
validation I receive the following error.
[Age Test Rule] [ERR 101] Line 4:2 no viable alternative at input 'Age' in
rule Age Test Rule
I then view the source and it looks like this.
rule Age Test Rule
dialect mvel
when
Age is less than 4years old
then
end
I noticed that there is no space between the ‘4’ and the word ‘years’.
However, in my DSL sentence there is a space between {age} and years.
Another interesting thing, if I enter the number 4 followed by a space in
the Guvnor form then the rule validates correctly. Is this a bug or is it
something I am doing wrong in my DSL?
Thanks,
Jeff

Re: [rules-users] Missing space when using DSL and Guvnor
Hey, didn't mean to come off as critical today. You are doing a good job on
this, and the basic rules stuff is spot on as far as functionality goes. Words
like *refactor* and *scrub* are just artifacts of code that has gone through
several revision cycles (and I helped). Functionally, it's working great, as
intended, with no compromises in the design - or at least tiny ones. If the
code is a little hard to modify (due to a couple of years of active
maintenance), that's not a big deal.
It really may be a very small deal. It looks to me like this code is about to
enter a fairly stable time. It's pretty close to feature-complete, and it's
working. So then it's your call if and when you want to spend the time and
effort to pretty it up a bit. In a code base as big as this one, with as many
things as need to be done, there's plenty of other low hanging fruit... :-)
Have a good weekend, and try not to work on this stuff.

It sounds like a bug. Can you double check it and create a jira issue please?
best,

I am setting up a very simple example using a DSL and Guvnor. My DSL is as
follows:
[when]Age is less than {age} years old=AgeFact(ageInYears {age})
When I attempt to create a new Business Rule using the Guvnor I can select the
above expression just fine and the sentence displays as expected. I then fill
in the years with a numeric value (4) and validate. Upon validation I receive
the following error.
[Age Test Rule] [ERR 101] Line 4:2 no viable alternative at input 'Age' in rule
Age Test Rule
I then view the source and it looks like this.
rule Age Test Rule
dialect mvel
when
Age is less than 4years old
then
end
I noticed that there is no space between the ‘4’ and the word ‘years’.
However, in my DSL sentence there is a space between {age} and years. Another
interesting thing, if I enter the number 4 followed by a space in the Guvnor
form then the rule validates correctly. Is this a bug or is it something I am
doing wrong in my DSL?
Thanks,
Jeff
