Re: [rules-users] Drools 6 Spring JTA Persistence

2013-09-04 Thread Alexander Herwix

Hey Martin,

haven't looked at your code yet, but I have Drools 6 CR1 and 2 running in 
grails though without local HT and JTA persistence. It was pretty straight 
forward, just included the dependencies and pruned duplicate entries (check the 
dependency report).

If I get the plugin working I would be glad to share a demo project. However, I 
think that a fully fledged release of the plugin to grails central would take 
some more time.

Cheers, Alex

 Hey guys, 
 
 I'm working on a Grails plugin for Drools/Jbpm 6 and I have trouble to get 
 persistence working in a user friendly way. It would be awesome if someone 
 with a better understanding of drools and especially drools spring 
 integration could help me to figure this out :) 
 
 I have considered multiple approaches:
 
 - Use a spring LocalContainerEntityManagerFactoryBean with a local 
 JpaTransactionManager to configure a KieEnvironment via Spring.
 
 I basically got this working, but this doesn't provide real integration with 
 Grails, as there are 2 seperate local TransactionManagers involved - 
 limiting the ability to integrate drools in the grails app.
 
 - Use JTA-Transactions. 
 
 As I want the plugin to be as user friendly as possible I would like to keep 
 using the default tomcat container for development. There is the Atomikos 
 Plugin for Grails which configures Grails to work with JTA. This works 
 pretty nicely and should suffice for the development environment. 
 
 My problem is integrating the Atomikos backed JTATransactionManager with the 
 drools 6 spring environment configuration as I have not much experience with 
 JTA. I have looked at the Tests for Kie-Spring and looked at as much 
 documentation as I could find, but I can't seem to figure this out. 
 
 This is what I use to configure the environment via spring (in Grails groovy 
 syntax)
 
 jbpmGlobals(MapGlobalResolver)
 
 dacceptor(ClassObjectMarshallingStrategyAcceptor,['*.*'])
 
 kie.kstore(id:'kiestore')
 
 kie.environment(id: 'jbpmEnv'){
 kie.'entity-manager-factory'(ref:'entityManagerFactory')
 
 kie.globals(ref:'jbpmGlobals')
 
 kie.'object-marshalling-strategies'(){
 kie.'jpa-placeholder-resolver-strategy'()
 
 kie.'serializable-placeholder-resolver-strategy'('strategy-acceptor-ref':dacceptor)
 }
 }
 //Tried to wrap my JtaTransactionManager with KieSpringTransactionManager
 jbpmTransactionManager(KieSpringTransactionManager, 
 ref('transactionManager'))
 
 the environment value for transactionManager cannot be set here, because the 
 parser expects a JpaTransactionManager. I tried to add the 
 transactionManager manually to the environment and found the 
 KieSpringTransactionManager, which looked like it could help me somehow, but 
 in the end, there is always the default implementation of the 
 JtaTransactionManager used which can't find the transactionManager that I 
 configured.

[rules-users] Fully qualified name for generated classes

2013-09-04 Thread Lance Leverich

What would be the fully qualified name for a generated class, that is based
upon a fact type (for example a type named Foo) that is defined inside a
declarative model?
How is the fully qualified name affected if the model resides in the Global
Area, and is imported into multiple packages?

The reason for my question is that I have the following issue:

In the Global Area, I have a declarative model (named MyModel) with a
definition like...
   declare Foo
  bar: String
  version: String
   end

In a package (com.mypkg.a), I have imported MyModel from the Global Area. I
have a rule like...

   rule myRuleA
   ruleflow-group firstGroup
   when
  not Foo( bar==bar )
   then
  Foo fact = new Foo();
  fact.setBar(bar);
  fact.setVersion(1);
  insert(fact);

In another package (com.mypkg.b), I have also imported MyModel from the
Global Area. I have a rule like

   rule myRuleB
  ruleflow-group secondGroup
  when
 Foo()
  then
 System.out.println(got at least one Foo);

Looking at logs, the rule myRuleA fires as is appropriate; however, the
rule myRuleB does not fire, even though both ruleflow groups are
represented in the ruleflow. I have verified that both of the ruleflow
groups are activated, using the logs. My best guess at this point is that
the class generated for fact type Foo is different for each package. So,
how can I make sure that I am instantiating and checking for the same type
across packages?

Re: [rules-users] Fully qualified name for generated classes

2013-09-04 Thread Lance Leverich

The issue isn't that Foo cannot be resolved, as it was imported into both
packages from the Global Area. The packages compile just fine. I believe
what might be happening, though, is that each package is creating its own
version of Foo.
For example, am I experiencing something like...
com.mypkg.a generates a class with a fully qualified name of
drools.com.mypkg.a.Foo
com.mypkg.b generates a class with a fully qualified name of
drools.com.mypkg.b.Foo
?

If this is the case, is there someway within Guvnor to refer to a
particular version? I'm beginning to think that my best option might be to
create a POJO and import it. At least that way, I can make sure I know the
fully qualified (i.e. canonical) class name.

 Guvnor's Global Area has no affect on fully qualified type names; it's
 just a container for things you want to share.

 If Foo could not be resolved in myRuleB the rule would fail to compile.

 What do you observations show if you don't have any rule flow?

It could be worth using the REST API to browse to the source of each package. 
It would be telling if the DRL included imports for com.mypkg.a.Foo and

Re: [rules-users] Fully qualified name for generated classes

2013-09-04 Thread Michael Anstis

Lance is correct.

Global Area in Guvnor is package agnostic; items in it only assume a
package when an item is imported into a package.

In the case of a declarative model the resulting class can be in multiple
packages depending on which Guvnor packages the item in the Global Area was
imported.

You can configure imports on the package configuration screen.

   version: String
end

 In a package (com.mypkg.a), I have imported MyModel from the Global
 Area. I have a rule like...

rule myRuleA
ruleflow-group firstGroup
when
   not Foo( bar==bar )
then
   Foo fact = new Foo();
   fact.setBar(bar);
   fact.setVersion(1);
   insert(fact);

 In another package (com.mypkg.b), I have also imported MyModel from the
 Global Area. I have a rule like

rule myRuleB
   ruleflow-group secondGroup
   when
  Foo()
   then
  System.out.println(got at least one Foo);

 Looking at logs, the rule myRuleA fires as is appropriate; however, the
 rule myRuleB does not fire, even though both ruleflow groups are
 represented in the ruleflow. I have verified that both of the ruleflow
 groups are activated, using the logs. My best guess at this point is that
 the class generated for fact type Foo is different for each package. So,
 how can I make sure that I am instantiating and checking for the same type
 across packages?

Re: [rules-users] Drools 6 Spring JTA Persistence

2013-09-04 Thread Alexander Herwix

Hey Markus,

that sounds really interesting! I would love to know your opinion on how to
integrate grails and drools in the best way. If we have similar ideas and goals
for the plugin that would be really good way to proceed. Maybe we can set up a
talk in irc or the like? I'm currently working on this full time so just hit me
up on my mail address to set something up.

Cheers, Alex

Hi Alex,

I'm developing a Grails Drools Plugin, too. At the moment I'm working on an
ECA (Event Correlation Analysis) solution so my current focus is on expert
fusion. But jBPM is also an important module that I'll need in the future.
Maybe we can come togehter and create one feature rich grails plugin.
Let me know if you're interested.

Hey Martin,

haven't looked at your code yet, but I have Drools 6 CR1 and 2 running in
grails though without local HT and JTA persistence. It was pretty straight
forward, just included the dependencies and pruned duplicate entries (check
the dependency report).

If I get the plugin working I would be glad to share a demo project. However,
I think that a fully fledged release of the plugin to grails central would
take some more time.

Cheers, Alex

Hey guys,

I'm working on a Grails plugin for Drools/Jbpm 6 and I have trouble to get
persistence working in a user friendly way. It would be awesome if someone
with a better understanding of drools and especially drools spring
integration could help me to figure this out :)

I have considered multiple approaches:

- Use a spring LocalContainerEntityManagerFactoryBean with a local
JpaTransactionManager to configure a KieEnvironment via Spring.

I basically got this working, but this doesn't provide real integration with
Grails, as there are 2 seperate local TransactionManagers involved -
limiting the ability to integrate drools in the grails app.

- Use JTA-Transactions.

As I want the plugin to be as user friendly as possible I would like to keep
using the default tomcat container for development. There is the Atomikos
Plugin for Grails which configures Grails to work with JTA. This works
pretty nicely and should suffice for the development environment.

My problem is integrating the Atomikos backed JTATransactionManager with the
drools 6 spring environment configuration as I have not much experience with
JTA. I have looked at the Tests for Kie-Spring and looked at as much
documentation as I could find, but I can't seem to figure this out.

This is what I use to configure the environment via spring (in Grails groovy
syntax)

jbpmGlobals(MapGlobalResolver)

dacceptor(ClassObjectMarshallingStrategyAcceptor,['*.*'])

kie.kstore(id:'kiestore')

kie.environment(id: 'jbpmEnv'){
kie.'entity-manager-factory'(ref:'entityManagerFactory')

kie.globals(ref:'jbpmGlobals')

kie.'object-marshalling-strategies'(){
kie.'jpa-placeholder-resolver-strategy'()

kie.'serializable-placeholder-resolver-strategy'('strategy-acceptor-ref':dacceptor)
}
}
//Tried to wrap my JtaTransactionManager with KieSpringTransactionManager
jbpmTransactionManager(KieSpringTransactionManager,
ref('transactionManager'))

the environment value for transactionManager cannot be set here, because the
parser expects a JpaTransactionManager. I tried to add the
transactionManager manually to the environment and found the
KieSpringTransactionManager, which looked like it could help me somehow, but
in the end, there is always the default implementation of the
JtaTransactionManager used which can't find the transactionManager that I
configured.

Re: [rules-users] Guvnor REST api, compile package

2013-09-04 Thread anchi

Ok, I somehow managed to resolve question 3 and 3.a. But questions 1. and 2.
remain, please point me to the right direction.

What I need is to build a package and if build was successful then create a
new snapshot.
My problem is how to build a package?

I found out that creating a new snapshot by calling
.../rest/packages/{packageName}/snapshot/{snapshotName} *sometimes* triggers
package build. But I cannot figure out how is this determined?

What I've found out is:
1. Approach that doesn't work:
  - update package version by sending modified package metadata to
.../rest/packages/{packageName} (I basically just change package
description)
  - then trigger creation of new snapshot with REST request
It does not compile the package

2. Approach that works:
 - click Save in Guvnor console (which changes package version)
 - then trigger creation of new snapshot with REST request
Package is compiled

So where is the catch? How can I make sure that package is built before
creating a snapshot?
I don't really see a point of having a REST interface if it still requires
to use Guvnor console for being able to use a knowledge base packages

Re: [rules-users] Guvnor REST api, compile package

2013-09-04 Thread Demian Calcaprina

About 1, .../rest/packages/{packageName}/binary will triger the compile and
then return the PKG. But not sure what will happen if the compilation
fails.. you can try!

From the documentation:
Returns the compiled binary of the package {packageName} as a binary
stream. If the package has not been compiled yet or its binary is not up to
date, this will compile the package first.

Re: [rules-users] Guvnor REST api, compile package

2013-09-04 Thread anchi

Thanks for your answer.
Yes, I've just tried this, it doesn't work.

In this part where it says ...or its binary is not up to date..., it does
not clearly say what criteria is used to determine that binary is not up to
date.

So this is my use case scenario:
1. I have a package that compiles
2. I'm using Guvnor plugin for Eclipse to update one of the assets (BPMN
file) with a new version that will cause compile errors
3. Now I try to create a snapshot with REST call and I want to get a compile
error (since package cannot compile anymore)

But Guvnor just doesn't detect the change (although I can see in console
that version number has changed for my asset, but not for the package).
