Pattern matching question
by Markus Wolf
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Hi, I have two questions for pattern matching with drools:
1. I have a multiline string to which a would match an expression. I've
tried that in various ways, but none worked. Is this not supported?
2. When I have a rule condition like this:
Somethin( test matches "abc def")
I'll get an exception during compilation saying "RuleError: Unable to
determine the used declarations". What does this mean?
When I remove the space and replace it with \s it does compile well.
Thanks for any help
Markus Wolf

classpath issue
by Krishnan
I am including the following libraries :-
D:\programs\java\jdk1.5.0\bin\javaw -classpath
"O:\fieldstation\jars\antlr\antlr-runtime-3.0.jar
;O:\fieldstation\jars\Drools\drools-compiler-4.0.0.jar

;O:\fieldstation\jars\janino\janino-2.5.7.jar" -Ddrools.compiler=JANINO
com.makesys.fs.app.adapter.AdapterServerWrapperImpl
I have included all the drools libraries, antlr library, janino library and
mvel library. I have also included the option to specify the JANINO
compiler. I have not done any code change to imply
janino compiler (Is this needed ?)
Below is the stack trace I get

Cannot recreate a rule or package in BRMS after archiving
by Shahad Ahmed
Is there a way of really deleting a rule or package in the BRMS? If you
archive a rule or package to delete it then you cannot create a new rule or
package with the same name as the archived assets - you get an error saying
the rule or package already exists!
The workaround I'm using at the moment is to rename a package or rule before
archiving it. This seems to allow you to create a new rule/package with the
same name as the original rule/package - but it isn't nice or intuitive.
Thanks

Hi,
I am getting the following error with 4.0.1, I didn't get this with

executing specific rules using agenda group
by prateek.katiyar＠wipro.com
Hi
I am using Drools 4.0.
First time I want to fire some specific rules from my rule file(in .xml format) and then other rules for the second time.
I have defined agenda-group attribute for the rules as follows:
<rule-attribute name="agenda-group" value="Check-rfq"/>
how can I execute specific rules using agenda group or is there any other options are available.
When I had gone through Drools documentation ,they mentioned Listener api can be used to execute specific rules but I did not find enough information on Listener.
Please let me know how can I implement Listener api to execute specific rules.
Thanks
With Regards
Prateek

ClassNotFound exception running brms example (newbie)
by Martin Fuzzey
Hi,
I am trying to run the insurance example with the brms
after replacing the client mvel jar with the one used by the brms web
app as mentionned on this list I get this exeception (full stacktrace below)
java.lang.ClassNotFoundException:
org.drools.rule.builder.dialect.mvel.MVELDialect$ModifyInterceptor
adding the drools-compiler-4.0.1.jar to the client classpath fixes this
but I thought the rules were supposed to be compiled by the brms. Indeed
the documentation says :
The rule agent is a component which is embedded in the core runtime of
the rules engine. To use this, you don't need any extra components. In
fact, if you are using the BRMS, your application should only need to
include the drools-core.jar in its classpath, and no other rules
specific dependencies.
so am I misunderstanding something or is this a bug?
Thanks,
Martin Fuzzey
