Re: [rules-users] Drools KB Object hierarchy Serilisation and Deserialisation thread safety issue
My experience switching a small project from 5.5.0.Final to 5.6.0.CR1 a few days ago, was that the only thing I had to do was change the Drools version number in my Maven pom.xml. It is a fairly simple project though, so it doesn’t exercise a great deal of the platform.

[rules-users] drools.package ResourceType?
Hi, I'm embedding Guvnor using the BRL Edition Mode. I'm then grabbing the BRL code and adding it to the KnowledgeBuilder. I'm also loading the object model jar using a class loader. This works fine if all the classes the rule is using are at the root of the object model jar. My question is, can I add the class imports (what the package.drools file does in guvnor) programmatically using KnowledgeBuilder, so my object model doesn't have to be flat? I was hoping there would be a ResourceType for drools.package, so I could do something like kbuilder.add(import package.classname, ResourceType.?), but can't seem to find one. Hopefully that makes some kind of sense to someone.. Any help on this would be greatly appreciated.

HI, drools.package was a Guvnor 5.5 (and prior) specific file used to add imports to rules etc generated inside the application. It has no analogy within drools-core itself.

Hi Mantis, thanks for your response. I'm using kbuilder.add(ruleResource, ResourceType.BRL); The BRL source code I grabbed from the embedded guvnor window doesn't have explicit path names on the classes that it's using. For example, if the class was packagename.Person it just has Person. Which means it tells me it doesn't recognise the class when I add it to class builder. I was wondering if there was a way round this? If not, it's not necessarily the end of the world to have to put everything in the root of the objectmodel jar.

Re: [rules-users] drools.package ResourceType?
Hello,
Unfortunately Guvnor 5.5 (and prior) only uses that file when (1) building
the package and creating the PKG file, and (2) when validating a rule.
More unfortunately (for you) there is no direct means to retrieve the
drools.package file either with REST (that I assume you're using for the
BRL rule).
You could retrieve the whole package source (IIRC something like
/package/{packageName}/source) and parse it for imports, but it's a long
winded way especially if the package is large.
That said it's only a one-off need; once you've parsed the imports you can
keep them locally.
With kind regards,
Mike

Thanks very much for both your responses. I've realised that I can add a DRL file to the kbuilder that just has the imports in it.

Re: [rules-users] kie-wb 6.0.0 tomcat7: Error uploading maven jar that is part of a multi-module maven project
Yes, I'm trying to upload the JAR to the kie-wb maven repository via the
kie-wb Artifact Repository page. Since the kie-ci module is already on the
webapps classpath, I assume there are no other work-arounds to try.
I debugged the MinimalPomParser method below and found the InputStream
passed in was a ByteArrayInputStream with a count of 10038 and it's position
was also 10038; as if it had already been read to end of file. While in
debug, I set the position to zero and let it continue. Sure enough, it
uploaded succesfully!
static PomModel parse(String path, InputStream is) {
MinimalPomParser handler = new MinimalPomParser();
try {
SAXParserFactory factory = SAXParserFactory.newInstance();
factory.setValidating( false );
factory.setNamespaceAware( false );
SAXParser parser = factory.newSAXParser();
parser.parse( is, handler );
} catch (Exception e) {
throw new RuntimeException(Unable to parse File ' + path +
', e);
}
Perhaps something is reading the InputStream before calling the parse method
and not creating a new InputStream to parse.
Unfortunately, I keep getting the error below when I try to add a drools
rule to my project. It is also failing in the MinimalPomParser because of
the same problem above.

Re: [rules-users] separating .drl declare type from actual .drl rule into each own file
It is supported, but you must be careful when you compile the DRL resources. You will have to compile the declares first and ensure that the classloader is set correctly. The easiest way to achieve this is to use the CompositeKnowledgeBuilder: KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(); kbuilder.batch() .add( ResourceFactory.newByteArrayResource( declares.getBytes() ), ResourceType.DRL ) .add( ResourceFactory.newByteArrayResource( rules.getBytes() ), ResourceType.DRL ) .build(); KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase(); kbase.addKnowledgePackages( kbuilder.getKnowledgePackages() ); Adjust the number and type of resources as needed. Notice that this feature is only available in more recent versions. If you want/need to use an older one, could you please specify which version and post the snippet of code you are using to build the KB? Thanks!
