Executing BRMS Snap shot
by SB.Raghavendra
Hi All,
I have a snaphot URL as :
http://localhost:8080/drools-jbrms/org.drools.brms.JBRMS/package/org.acme...
.
I configured above URL in one propertied file and accessing in one class i
written flollowing code in the class that iam going to execute.
private static RuleBase loadRuleBaseFromRuleAgent() {
RuleAgent agent = RuleAgent.newRuleAgent(
"/brmsdeployedrules.properties" );
RuleBase rulebase = agent.getRuleBase();
return rulebase;
}
*But iam getting following error :*

Is there any way to get the original eval expression through AfterActivationFiredEvent event?
by manrai.java
Hi,
I am using JBoss rules 3.0.6 to externalize all business rules. We have a
requirement were in we want to create a audit report after rules have been
executed. For each rule, we need to track Desired Condition Value(as
specified in when part), Actual Condition Value(value in asserted object)
and so on.
I looked into Event Model API's and was able to successfully fetch required
data from call back methods provided by DefaultAgendaEventListener for most
of the rules.
However, In my application there are some rules which use EvalCondition(I
know that using eval is not a good idea but it will remain like this for
quite some time). I am not able to fetch required data from EvalExpression.
On introspecting Eval Expression i am getting something like (proxy object):
TestIt.Rule_FirstRuleToTest_0Eval0Invoker@feefa5e0
What i am expecting is something like below:
**
*eval*( Income.getGrossIncome().doubleValue() == 10001)
Is there any way to get the original eval expression through
AfterActivationFiredEvent event?
Regards,
Mohit Manrai

startProcess("String") on StatefulSession.
by SB.Raghavendra
I am getting one exception as : No SuchMethod Exception session.startProcess
(Ljava.lang.String) when i executing the following code in one of the class
:
public static StatefulSession getSession() {
if ( rulebase == null ) {
rulebase = loadRuleBaseFromRuleAgent();
}
session = rulebase.newStatefulSession();
System.out.println("strting process...");
session.startProcess("insuranceProcess");
System.out.println("Started Process..");
return session;
}
In above code if i commented out line :
session.startProcess("insuranceProcess");(In
above code..) the error was resolved and executing properly..
please let me know why we need to code :
session.startProcess("insuranceProcess");.if
i am not using startProcess("String") method,Does it create any session
problem anywhere.Please guide me on this.......

checking for complex conditions
by Jai Vasanth
Hi,
Suppose I have a class Foo with integers a, b and c ( methods getA getB
and getC respectively ) and I Want to check if an object of Foo satisfies
a - (b + c) > 0
Is this the best way I go about doing this ?
rule "Foo check"
when
Foo( varA : a , varB:b, varC:c )
eval( varA - (varB + varC) > 0 )
then
<do actions>
end
Writing this as
rule "Foo check"
when
Foo( a - (b + c) > 0 )
then
<do actions>
end
doesnt seem to work. Its not able to find the variables (a, b and c ) from
the getA getB and get C methods.
Thanks

Re: [rules-users] Strange exception
by Edson Tirelli
Are you using "contains" operator to check a hashmap for the existence of
a value? "contains" should only be used with collections, not maps...

generated class.
Any ideas of what could be wrong here?

Strange exception
by Brian Trezise
I'm getting a strange exception upon inserting an object into working
memory. Relevant information follows:
I'm creating a "smartdescription" which contains a string and some
information about that string that is later added by the rules. With the
exception of one specific string, this seems to be working perfectly. I'm
using regexes to match the strings.
This is the regex where I'm having the problem:
public static final String REGEX_APPLICATION_CURRENT_SENSE = ".*(" +
"CURRENT[ .]?SENSE?" + ").*";
and the smartdescription string I'm testing is "aaaaaaaaaaaaaaaaaaa current
sense aaaaaaaaaaaaa".
I have determined that any other string that matches any of the identically
formulated rules works with no problems. If I put in something that doesn't
match this regex, there is no exception. The RHS of the rule in question is
not reached in this case.
This is the exception:

Compare two variables in Web based BRMS
by Sergio Soria Olivares
Hi, I have a problem in the web interface drools-brms when I try to
compare two variables, one of them with null value. If I try to compare
with this situation, the system throws a nullPointerException, and I
can't do anything. If I assign a value to this variable, the system
works perfect.
Nevertheless, if I do the same in the eclipse drools tool, all do
perfect, and I can give a null value for a variable, because later the
variable will recover the value in the program, when the rule is call.
Pleased help me, because I think that it's a great bug.
Lot of thanks.
