Re: [rules-users] Drools causes switch(enum e) to break?
by SydneyTechHead
I've reproduced this issue with a simple example:
1. Create a new "Drools Project" in Eclipse Kepler with Drools 6.0.1.Final
installed (JDK 1.7) with simple "Hello World" rule example. Project builds
OK.
2. Create the following new class:
public class EnumTest {
private enum EnumType { On, Off }
private EnumType et = EnumType.On;
public EnumTest() {}
public String TypeText()
{
switch(et)
{
case On:
return "On";
case Off:
return "Off";
default:
return "";
}
}
}
3. Rebuild project. Eclipse reports Problem:
Drools Error: "Cannot switch on a value of type EnumTest.EnumType. Only
convertible int values or enum variables are permitted"
4. Export Ant Build file for the project and run the Ant Build. Build
successful.
5. Create a vanilla Java Project (no Drools) and add the same EnumTest
class. Eclipse project builds OK.
As the project builds OK via Ant, it appears that this is an issue with the
Eclipse incremental builder conflicting with Drools 6. As noted in my
previous post, it appears that Eclipse may be reducing JDK compiler
compliance level down to 1.5 or referencing JRE 1.5 in class path as a
result of this conflict, as I've occasionally noticed it changing these
settings in project properties.
Any ideas or clues why this may be the case and what is the best channel to
report this Eclipse issue?

Drools Fusion (CEP) & event life cycle
by Ephemeris Lappis
Hello.
I'm testing event processing in Drools, and after some basic tests, I have
some questions about event life cycle management.
According to the documentation, in stream mode, events may be automatically
discarded by the engine when no rule, currently or in the future, applies to
them.
In the following rule set (at the end of my post), the rule named
"Processing new alert event" is expected to be executed when a new 'alert'
notification event arrives and no previous alert exists. After an elementary
test, the first matching notification produces the expected behavior and
generates the Alert. But if a second matching notification is inserted, the
rule is ignored as expected, since the Alert is already set, but the event
object seems to be put durably in memory. When a 'stop' notification is
inserted, the Alert object is cleared by the rule "Processing stop event
after alert", as expected, but the second 'alert' notification that should
be forgotten is raised from the memory and the first rule is fired again,
creating an undesired second Alert.
I've tried a workaround adding an "opposite rule" to check the processing of
an 'alert' notification when there is a current Alert. As at the moment the
notification object is inserted the two rules are candidate in the agenda,
both are executed. I suppose I could try, for example, adding salience
values to make the rules execute in a deterministic order...
As you can see, I've added explicit deletion of the notification objects in
the rules, and all seems to work as needed. But it seems really a bit
cimplicated, and contradictory with the documentation...
What did I miss ?
Thanks for your help.
Regards?
Here the rule set :

NPE in LeftTupleSetsImpl.removeUpdate
by David Zeigler
Hi,
I'm using drools 6.0.1.Final. I received a NPE in the
org.drools.core.common.LeftTupleSetsImpl.removeUpdate() method on line
172, which
corresponds to this line for 6.0.1.Final:
previous.setStagedNext( next );
I see 2 commits in 6.1.0 to address NPEs in this class but I'm not sure if
either of those cover this particular NPE. I'm unable to reproduce this
issue with my code after the first occurrence. Does anyone know if this
has been fixed in 6.1.0? Please let me know if I can provide additional
info or if I should open a defect in Jira.
Thanks,
David

Trying to load a module from Maven coordinates
by david.berkman
Using Maven 3.2.1 and Drools 6.0.1, I'm trying to simply follow the
instructions for loading a container with a jar at a set of maven
coordinates. I have confirmed that the jar exists at the specified
coordinates (in Nexus), and that I can download it without using a
username/password (just an http get), and that the jar does contain both
.drl files and a /META-INF/kmodule.xml. I'm using the code below, and have
added the extra dependencies listed, but I get the errors shown below all
that. First off, working out the proper dependencies is no mean feat, when
it seems that just kie-ci should be necessary. What a pain, and there is far
too little documentation to help. But, I assume this should be possible, and
maybe some kind person out there has the magic combination of Drools, Maven,
and jars to make it work?
Thanks in advance,
David

Usage of the jcr2vfs migration tool
by dstern
Are there instructions anywhere for using the jcr2vfs migration tool?
I pruned my JCR repository (created under Guvnor 5.6.0.Final) until the
migration tool ran without error (which meant archiving all my brl format
assets among other things) but I'm not sure what to do with the output.
I copied the contents of outputVfs to my existing .niogit folder (leaving
the .niogit generated by the migration tool alone) but the migrated
repository doesn't show up. Is this because I didn't replace my existing
.niogit with the one generated by the tool?

Including repository in a WAR file
by ilguapo
I'm using Drools 5.3.0
I'd like to find out if the following scenario is possible:
- Include the repository_export.zip file inside my application WAR file.
This way, Guvnor won't be necessary.
- Provide a special upload page just like Guvnor's Import/Export to upload a
completely new repository_export.zip file when rules have changed.
I haven't been able to find a way to read a repository_export.zip file with
the current API. They only talk about drl, pkg, etc..etc but no zip files.
I could potentially take the zip file, unzip it to an XML and maybe read
this file??
Any ideas would be really helpful.
Regards,
Ilguapo

Drools 6.0.1: Pushing changes back to Workbench GIT using SSH
by dotrc
I am using workbench for managing my rules maven projects within the embedded
GIT repository. I am aware that using git:// protocol, I can clone an
existing rule repository; I can do this successfully.
For authoring rules, I want to use Eclipse (using EGit). I want to push my
commits back to the GIT repo. I understand that I'll have to use ssh
protocol instead of git for specifying the repo, something like this:
ssh://{userName}@localhost:8001/{repoName}
When we use a standard GIT repo like stash, it gives us an option to set our
public key on the stash server, but I'm not able to find a way to do that
with the embedded ssh server within workbench. Hence, I'm not able to
authenticate myself and perform a push.
We tried creating a private-public key pair using ssh-keygen and put that
within c:\users\<username>\.ssh and added the public key to
'authorized_keys(2) (though I know this may not be the right place) and then
used the private key as the identity file with ssh client directly from
cygwin, again to no avail.
Any pointers will be really appreciated.
Also, should the username be 'admin' or any other specific one for pushing?
Will the existing Windows username work?
Thanks,
Rishi

Drools 5.6.0.Final PKG vs DRL infinite loop
by gboro54
We are using drools 5.6.0.Final and the same version of Guvnor. When we run
the source file of a package from Guvnor everything works as expected. When
we take the same rules and create a package we get stuck in an infinite loop
of rules firing(I have a listener logging every time a rule is
created/fired). Why would there be a difference if the rules don't change
between the source and the pkg?
We build the kbase as follows:
KnowledgeBuilderConfiguration config = KnowledgeBuilderFactory
.newKnowledgeBuilderConfiguration();
config.setOption(PropertySpecificOption.ALWAYS);
KnowledgeBuilder kbuilder = KnowledgeBuilderFactory
.newKnowledgeBuilder(config);
for (ResourcePair pair : pairs) {
/* kbuilder.add(
ResourceFactory.newClassPathResource("rule-sets/2014/feb/"+pair.resourceName),
ResourceType.getResourceType(pair.resourceType));*/
kbuilder.add(
ResourceFactory.newClassPathResource(pair.resourceName),
ResourceType.getResourceType(pair.resourceType));
}
KnowledgeBuilderErrors errors = kbuilder.getErrors();
if (errors.size() > 0) {
StringBuilder sb = new StringBuilder();
for (KnowledgeBuilderError error : errors) {
sb.append(error + "\n");
System.out.println(sb);
}
throw new IllegalArgumentException("Could not parse knowledge.
\n"
+ sb);
}
this.knowledgeBase = KnowledgeBaseFactory.newKnowledgeBase();
this.knowledgeBase
.addKnowledgePackages(kbuilder.getKnowledgePackages());
