Re: [rules-users] ArrayIndexOutOfBoundsException in MVELCompilationUnit
by Stephen Masters
Actually please ignore. I temporarily upgraded to 5.4 which identified a bug in a DSL. With that fixed, I was able to downgraded again.
Thanks anyway!

Problem with guvnor db mysql jndi
by Leonardo Soubeste
Hello everyone,
I'm trying to use Guvnor repository with mysql. I'm using JBoss7.
I configured the datasource as jndi resource like this:
<datasource jta="true" jndi-name="java:jboss/datasources/guvnor"
pool-name="guvnor" enabled="true" use-java-context="true" use-ccm="true">
<connection-url>jdbc:mysql://localhost:3306/guvnor</connection-url>
<driver>com.mysql</driver>
<transaction-isolation>TRANSACTION_READ_COMMITTED</transaction-isolation>
<pool>
<min-pool-size>10</min-pool-size>
<max-pool-size>100</max-pool-size>
<prefill>true</prefill>
</pool>
<security>
<user-name>root</user-name>
<password>password</password>
</security>
<statement>
<prepared-statement-cache-size>32</prepared-statement-cache-size>
<share-prepared-statements>true</share-prepared-statements>
</statement>
</datasource>
Now, when I run guvnor I get this exception:
Caused by: java.sql.SQLException: You cannot set autocommit during a managed
transaction!
at
org.jboss.jca.adapters.jdbc.BaseWrapperManagedConnection.setJdbcAutoCommit(BaseWrapperManagedConnection.java:888)
at
org.jboss.jca.adapters.jdbc.WrappedConnection.setAutoCommit(WrappedConnection.java:715)

at
org.apache.jackrabbit.core.util.db.ConnectionHelper$3.call(ConnectionHelper.java:339)
[jackrabbit-core-2.2.8.jar:2.2.8]
I think is related to the <transaction-isolation> tag. Any help?
I couldn't find any example of how to configure this. Without using JNDI it
works.
Thanks in advance

Re: [rules-users] Unable to download the deployment files pointed in the Guvnor documentation pages.
by EvelthonPatrickios＠tsys.com
Drools Guvnor Documentation for PDF points to:
http://docs.jboss.org/drools/release/5.5.0.Final/drools-guvnor-docs/pdf/
drools-guvnor-docs.pdf
where it SHOULD point to:
http://docs.jboss.org/drools/release/5.5.0.Final/drools-guvnor-docs/pdf/
guvnor-docs.pdf
(or change the target file name)
Same is true for some of the previous versions. (5.5.0.CR1, 5.4.0, etc)

ArrayIndexOutOfBoundsException in MVELCompilationUnit
by Stephen Masters
Hi folks,
I seem to have come across an issue with hitting an ArrayIndexOutOfBoundsException:3 during an insert. It seems to depend on how many other facts have already been inserted.
This is on 5.3 Final.
Can anybody give me any pointers on how to diagnose such an issue?
Many thanks

Hi,
the link still seems broken to me, but the other link you gave me did the trick.
Thanks a lot.

I have correct the link in the documentation.
5.4.0.Final can be obtained from
http://download.jboss.org/drools/release/ which is included within the the "Other downloads" section of my original link.

Hi,
Let me first say that I am new to Guvnor, but the functionality which it present seems to be really good and just the thing that I need at the moment.
So I decided to give it a try and see it in action. I began to read the documentation and the "Installation" section in it:
http://docs.jboss.org/drools/release/5.4.0.Final/drools-guvnor-docs/html_... (I am trying to use guvnor-5.4.0)
And there is a link there for deployment files download, which i failed to download since yesterday.
Can you please take a look in it and tell me if the files are moved or if there is a problem with the server they are hosted on?
Big thanks for your support!
Best Regards,

expectation for -Ddrools.dump.dir to show DRL error context ..
by Cotton, Ben
Hi,
I thought this worked for me at some point, but, I now seem to have lost my ability to get any debuggable DRL error contexts via the -Ddrools.dump.dir property.
Here is my command line, that simply borrows from the DROOLs sample package's Cheese.xls SpreadsheetCompiler example , to produce a .DRL from an (.XLS, .DRT) input pair:
java com.ms.fast.triclear.eligibility.rules.GenerateDRLfromEligibilityRulesRepoViaDRT \
-Ddrools.dump.dir=./DroolsDumpDir \
../main/packages/com/ms/fast/triclear/eligibility/rules/IRD_PRODUCT_RULES_FEED_TO_DRT_Template-BASIS.xls \
../main/packages/com/ms/fast/triclear/eligibility/rules/IRD_PRODUCT_RULES_TEMPLATE-BASIS.drt \
2>&1 | grep -v Picked | \
tee ../main/packages/com/ms/fast/triclear/eligibility/rules/IRD_PRODUCT_RULES=RENDERED.drl
This command line produces the following errors:
Error compiling resources:
[ERR 102] Line 923:0 mismatched input ''
[ERR 101] Line 8:60 no viable alternative at input '"LCH US"' in rule "IRD_PRODUCT_RULE_24"
[ERR 101] Line 46:60 no viable alternative at input '"LCH EU. SCM"' in rule "IRD_PRODUCT_RULE_23"
Parser returned a null Package
Exception in thread "main" java.lang.IllegalStateException: Error compiling resources
at com.ms.fast.triclear.eligibility.rules.GenerateDRLfromEligibilityRulesRepoViaDRT.buildKBase(GenerateDRLfromEligibilityRulesRepoViaDRT.java:93)
at com.ms.fast.triclear.eligibility.rules.GenerateDRLfromEligibilityRulesRepoViaDRT.execute(GenerateDRLfromEligibilityRulesRepoViaDRT.java:50)
at com.ms.fast.triclear.eligibility.rules.GenerateDRLfromEligibilityRulesRepoViaDRT.main(GenerateDRLfromEligibilityRulesRepoViaDRT.java:44)
Unfortunately, my ./DroolsDumpDir/ directory contents are completely empty. I was hopeful it might contain a staged .DRL context from which I could more easily debug my roadblock.
Is there more that I have to do, beyond just passing -Ddrools.dump.dir=./DroolsDumpDir on the command line?

BRL and Agenda-group
by TonyN
Hi,
I am using Guvnor 5.4 Final and having a hard time getting BRL rules and
agenda group to work. Seems like if I don't assign the agenda-group then
the rules would file, but if I set agenda-group (brl, declaratively) and use
DRL to set the focus, then the rules don't get fired.
Is it possible to use BRL and Agenda-group together or does Agenda-group
only work w/ DRL rules?
I'm wondering if there is something that need to enable or anything?
thx,

Problem sharing declarative model between two packages
by Al
I would like to be able to share a declarative model between two packages.
When I attempt to do this by creating my model in Guvnor's Global Area and
then importing it into each package, I find that instances of the declared
types that are created by rules in one package are not recognized by rules
in the other package.
For example, suppose I create a model in the global area with a declared
type:
declare MyType
field1: String
end
I then import this model into packages "p1" and "p2". I add the following
rule into package "p1":
rule "create it"
when
eval(true)
then
MyType m = new MyType();
insert(m);
end
and I add the following rule into package "p2":
rule "find it"
when
$m : MyType()
then
System.out.println("found it");
end
At runtime, the "create it" rule fires and inserts a "MyType" object.
However, the "find it" rule never fires.
If I add a WorkingMemoryEventListener and look at exactly what is being
inserted, I can see that the "create it" rule is inserting an instance of
p1.MyType. I assume that the "find it" rule is looking for an instance of
p2.MyType and that is why it never fires.
Is there a different way to accomplish this? Or, are declarative models
simply not intended to be shared across packages?
