Re: [rules-users] Resource Change Scanner Service modified date error
Could you please share with us how are you adding your resources to the
agent? According to what you are saying I assume you are using a
ReaderResource. According to Drools code, ReaderResource doesn't support
most of org.drools.io.internal.InternalResource methods. Some of these
methods (i.e. getLastModified()) are used by ResourceScanner to check if a
resource has actually changed.
So if we take a look at ReaderResource.getLastModified() we will see this:
public long getLastModified() {
throw new IllegalStateException( reader does have a modified date );
}
You can find the whole source code here:
https://github.com/droolsjbpm/drools/blob/master/drools-core/src/main/java/org/drools/io/impl/ReaderResource.java
So, don't expect this to work :)
There are 2 things you can do:
1. Submit a patch for ReaderResource.java implementing all the
unimplemented methods :)
2. Use a different Resource like UrlResource, FileResource,
InputStreamResource, etc.
In my opinion, Bug 733008 must be reopened until someone (maybe you Dean)
provides a correct implementation of ReaderResource.

Re: [rules-users] Resource Change Scanner Service modified date error
Enlighten me, please.
If ResourceFactory.newReaderResource() creates a drools.io.Resource from a
java.io.Reader, how would you get at some modification time, and of what?
The general idea of a Reader seems to be a data source without implication
as to data representation, persistence, file system or any other such thing.

Re: [rules-users] Resource Change Scanner Service modified date error
As Dean says, getting the modification time of an in-memory resource is impossible (actually you need to create an external mechanism to keep track of it). So I would suggest to change the thrown Exception to something more meaningful and to explicitly document which resources are capable to be scanned for changes. Right now, the Resources capable to being scanned are: - ClasspathResource - UrlResource - FileSystemResource - EncodedResource (depending on the implementation of Resource it is using) @Wolfgang, for non in-memory Resources like files or url resources you can get the last modified time. This is used by the scanner to check if a particular resource has been modified since the last time it was scanned. As Dean mentioned, this is not feasible when the resource is an in-memory resource like a ByteArrayResource.

[rules-users] MVEL curly braces position - bug or feature?
Hi
I've been learning drools ands I saw that there is a Fibonacci example, so I
thought I'd write my own using mvel as the dialect and then compare it to
the model solution.
However, I couldn't get mine working. It parsed but the behaviour was very
odd. It kept ignoring the modify block in my recurse rule and consequently
it went into an infinite loop. I compared it to the 'approved' solution and
the two were pretty much the same, except that it worked and mine didn't.
After a lot of checking I noticed that I had started my curly brace on a new
line after modify but the example had continued straight after the closing
brace of the modify.
Works //
modify ( f ){
value = 1
};
or
modify ( f ){value = 1 };
Doesn't Work //
modify ( f )
{
value = 1
};
Does anyone know if this is a bug or a feature?

Re: [rules-users] MVEL curly braces position - bug or feature?
Looks like a bug. MVEL does ; injection in order to make ; optional, so
my guess is that it is mistakenly injecting ; after your modify() call and
handling {} as a separate code block.

it went into an infinite loop. I compared it to the 'approved' solution and
the two were pretty much the same, except that it worked and mine didn't.
After a lot of checking I noticed that I had started my curly brace on a
new
line after modify but the example had continued straight after the closing
brace of the modify.
Works //
modify ( f ){
value = 1
};
or
modify ( f ){value = 1 };
Doesn't Work //
modify ( f )
{
value = 1
};
Does anyone know if this is a bug or a feature?

Re: [rules-users] Sending requests to the Drools Execution Server from an external source
I am not sure, have you looked in the log file of the drools server
(catalina.out if you are running on tomcat)? Also have you configured the
server to consume JSON rather than XML?

Re: [rules-users] Sending requests to the Drools Execution Server from an external source
It has been a while since I worked with this and it may have been updated. This might not be your issue but I my camel-server.xml looks like this, note that the converters and aliases tags are not necessary, but if you find yourself needing an xstream alias or convert, that is where you would configure them. I would check your server log file too. dataFormats xstream id=xstream-json driver=json converters /converters aliases /aliases /xstream /dataFormats route from uri=cxfrs://bean://rsServer/ policy ref=droolsPolicy unmarshal ref=xstream-json / to uri=drools:node1/ksession1 / marshal ref=xstream-json / /policy /route On Fri, Jan 6, 2012 at 2:03 PM, kofibentum [via Drools] ml-node+s46999n3638652...@n3.nabble.com wrote: Yes I am using tomcat 6.

[rules-users] Guvnor utility to update packages and models
We are using Drool and Guvnor 5.1.1 and have approximately 150 rule packages (different rules for different customers, ...). Has anyone written a utility or do you have a suggestion for updating POJO models within each of these that doesn't involve me going to each package within guvnor? As an example, 50 of my packages might all use the same POJO, we'll call it transactionAv10.jar, and when I go to v11 I currently have to go back into each package in guvnor and archive v10 and then upload v11. I'm looking for a way that I could do this outside of guvnor. Whether it be doing the updates at the webdav level, or even calling some guvnor functions that do these tasks. For reference, I am using Apache Tomcat to host Guvnor and am using the default database structure. Any thoughts? Thank you!

[rules-users] i want to user drools/Guvnor
Hi I am newbie in Drools, I got an assignment and I found Drools / Guvnor could be the perfect match for this requirements. I have a huge database in mySQL in a school (where it has data from kinder garden kids to PhD students). Management hired a sport medical doctor to check the health of existing students to prepare a good soccer team. The teacher want to find these kind of students. a) students who are within age of 18-21 years old (sample only), parents allowed to play soccer (let say the targeted population) b) Among these population he want to screen who has encounter with minor diseases and visited hospital in last year. c) in that medical visits he want: 1. student more than 2 visits with chest or leg pain or 2. under medication with (drug1, drug3, drug7, drug 11). or 3. student lab test result show nicotine level (smoking) 48 or 4. student lab test result show alcohol level =1.8 or 5. any chest pain (while running) or leg fracture. These are the criteria he decided to pull from another software but I can get XML file, which is infact a rule. He want me to write a rule, where he can apply same pattern but for another game in future i.e. volleyball players (where hand fracture is major determinant). and return result in a format which has been written in Java script. after studying Drools, I decided Guvnor would be the best tools to apply. Now my problem is: a) How can I map xml criteria to Drools. b) How can I access Guvnor UI (for rule writing by non IT guy) with Existing school's Software. c) How can I visualize the results in Java script (already written). so I don't have to work hard for visualization. Any suggestion / ideas / steps are welcome. DG ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
[rules-users] NPE loading Drools 5.4.0.Beta1 using drools-spring
I am trying to load up 5.4.0.Beta1. I'm using Spring configuration xml that works fine in 5.2.0.Final. In the xml, my grid-node is defined as: drools:grid-node id=droolsClusterNode1/ The exception is a NPE on a method in WhitePagesClient. Any idea what the cause might be?

Re: [rules-users] Guvnor utility to update packages and models
Hi, This is the exact reason why you may want to use the Global Area. Global area is a special area that is designed to store assets that can be shared among all packages. First, put your common pojo in the Global Area. Then add pojo to each package using the Import from the Global Area option. Further more, you can update your pojo through REST interface remotely when you pojo model is changed: http://docs.jboss.org/drools/release/5.3.0.Final/drools-guvnor-docs/html/ch09.html#d0e2282 Cheers, Jervis On 2012/1/7 4:15, Dean Whisnant wrote: We are using Drool and Guvnor 5.1.1 and have approximately 150 rule packages (different rules for different customers, ...).
