BPMN2 Question
by starfish15
Hello,
I am very new to BPMN. We are currently using Drools 5.3 version. I face the
below error when i run the project. Also am trying to understand the running
of Call Activity. Anyways a flow does begin running and then it gives the
following error
java.lang.NoSuchFieldError: session

Not sure i understood this error. Would appreciate if some help could be
provided with what the error meant exactly.

starfish.

Error Guvnor and Form Builder on Different Nodes in JBOSS
by Zahid Ahmed
Hi,
I am having an issue in integrating GUVNOR and JBPM-FORM-BUILDER when I deploy guvnor and form builder on different nodes. I am getting Http-500 : Error getting task from Guvnor. Or I am getting Http 404 : /jbpm-form-builder/embed. It asks for authentication to form-builder And the error comes after successful authentication. I cannot find any server log printed, only the error comes on screen. Attached is the screen shot.
All works fine when I deploy guvnor and form builder on the same node. But on different nodes the errors are seen while opening/creating the form definitions from guvnor.1
Environment :
Node 1:
1. drools-guvnor.war
2. designer.war
Node 2:
1. jbpm-form-builder.war
Server tried with
a. Jboss EAP6.0.1
b. Jboss AS-7.1
2. Guvnor 5.4.0
3. Jbpm-form-builder 5.4

Re: [rules-users] [uberfire-users] Configurable and Reusable Editor
by Michael Anstis
All Drools and jBPM components use the Uberfire framework.
Any individual component can be used in isolation (subject to inclusion of
any dependencies) by any other Uberfire compliant application.
Vice-versa any 3rd party Uberfire compliant component can be used within
the Kie Workbench extending its functionality.

Re: [rules-users] NoSuchFieldError: session
by Lance
As it turned out, this problem came about because I had a model that was
based on a POJO jar file. The jar that was in Guvnor contained the
offending field(s), but when the package was being loaded it was using a
version of the jar that did not contain the offending fields. This served
as a lesson to me, demonstrating why updating the serialVersionId is an
important step in managing POJOs.

Using Java Rule Engine JSR-94
by abhinay_agarwal
Hey,
I read about JSR-94 and found it quite useful, so was trying to do a POC on
its usage. These are the steps which i followed.
1. Made a new java application.
2. Added the JSR-94 api jars in its build path.
3. Made a rule as myRuleFile.drl
4. Wrote a RuleAdapter class as shown in drools expert document Chapter 5.
The Java Rule Engine
API (JSR94).
But when i tried to run the piece of code, it kept giving me errors related
to Class missing related to drools.
Are are the drools jar required to run this example,if yes, then what is the
avantage of using jsr-94 api ?
If any specific jars, can you please list them out?
If I am doing anything wrong, then, can you please point me to the correct
direction.
Thanks,
Abhinay

Drools Fusion Dropping Events?
by Jason Barto
I've been working to load test Drools 5.3 to determine if its a fit for a
project. As part of the test I programmatically insert events as rapidly
as possible; an example, my earlier test inserted 10k events in about
300ms. There is currently a single rule which reads the event and stores
the event's value into the only fact in Drools. I'm very happy to report,
and I'm sure it will be no surprise to anyone, that the engine processes
all the events in roughly 1 sec. However I have noticed that any large
number of events (~>1000) usually sees that a small number of events don't
get processed. I think after 10k events as many as 7 appear to have gone
unprocessed. If 100 events are inserted, rather than 10k, no events get
disregarded. Being new to Drools I can easily accept that my java code or
DRL code is off or unoptimized in some way. However not knowing how Drools
does its magic I'm currently inclined to think that Drools gets swamped
(10k in 300ms is a lot) and a few events get dropped so Drools can keep
operating. Is this a known or expected behavior from Drools? If not I am
happy to post my code, it is similar to the other code sets I've posted in
the last few days. I'm still new to Drools and trying to learn its behavior
so any insight or enlightenment is greatly appreciated.
Sincerely,
Jason

Error : JAAS Authentication with Guvnor 5.5.0 and Authorization Error
by Zahid Ahmed
Hi,
I have run into a set of errors configuring JAAS Authentication for Guvnor. I have searched a lot on jboss community and for all the solutions nothing is working for me. I am getting either the login popup or I am getting "This User has no permissions setup". The Guvnor Manual is referring to jboss eap 5 and I am trying to do this on Jboss AS 7.1.
Note : I am unable to find login-config.xml file mentioned in the following link. http://docs.jboss.org/drools/release/5.5.0.Final/drools-guvnor-docs/html/... . Is guvnor deployment targeted only for JBOSS EAP 5.0 ?
Environment:
1. Guvnor 5.5.0.Final
2. JBOSS AS 7.1.0
Files Configured (Only these files I configured):
1. Standalone.xml
2. Guvnor.war/WEB-INF/beans.xml
3. Created users using "add-user.sh"
4. standalone/configuration/application-users.properties (attached).
5. standalone/configuration/application-roles.properties (attached)
6. standalone/configuration/management-users.properties
Configurations
Standalone.xml :
Only configured below tags. There's nothing else I changed for the purpose of JAAS Authentication and Guvnor Authorization. Added <security-domain name="drools-guvnor" cache-type="default"> to check if "other" is not working.

I HAVE ALSO ADDED THIS COMPONENT TAG found every where on forums to resolve this issue. I tried Tried without this also but at that time I get LOGIN screen which always says Incorrect User/Password.Is this required or <guvnorSecurity:RoleBasedPermissionResolver> is the only authorization config.
<component name="org.jboss.seam.security.roleBasedPermissionResolver">;
<s:modifies/>
<property name="enableRoleBasedAuthorization">true</property>
</component>
Kindly help me in this configuration. I can't find a single authentic document for my environment.

Drools 6.0.0.Beta2 Documentation and Examples
by 445511
I'm trying to use Drools 6.0.0.Beta2 but none of the examples appear to be
"Kie"-ified making it difficult to figure out. Is there more up to date
documentation concerning Drools 6 without pooring through source code?
I'm specifically interested in drools + jbpm, new annotations, git
integration, maven integration, new Drools UI (the uberfire one which I'm
still unclear whether this is going to be called guvnor or something
completely different).
I realize how hard it is to work on a project and document at the same time
- especially given the multi-continent talks coming up but this has been an
ongoing struggle with JBoss based projects. The early releases (and even
final) lack sufficient accurate documentation to even evaluate its use. I
can only assume that this substantially reduces support contract
opportunities and frustrates early adopters.
Any pointers will be greatly appreciated.
