Oryx exported BPMN not properly opened in Eclipse Drools.
by Robert
Hi,
my exported BPMN-File from the Oryx-Editor does not open properly in the
Eclipse-Drools IDE.
I set the BPMN-Skin and the Editor is actually open up, but the only
symbol displayed is the start-node (but there are actually many more)
What did I do ?
I followed the demo at
http://people.redhat.com/kverlaen/BPMN2-OryxEditor.swf
for creating a BPMN 2.0 model.
But somehow the recent version of Oryx seems different.
First there are some more options of creating a new modell:
- BPMN 2.0 Process
- BPMN 2.0 Conversations
- BPMN 2.0 Choreographies
- ...
I choose the first (BPMN 2.0 Process).
At exporting it, it looks also somehow different:
- ...
- Show BPMN 2.0 DI XML
- Download BPMN 2.0 DI XML
- ...
There are others, but nothing looking close to the one used in the demo
(there you used "Show BPMN 2.0 XML", so the "DI" is different).
I guees the format changed somehow.
Can you give me some feedback on this, if you also encountered problems or
give me a hint what I did wrong ?
Thanks.
Cheers, Rob.

A question about web Guvnor and Standalone Guvnor
by Gavin Wang
Hi all:
i'm a newbie to drools.
when i deployed the guvnor 5.0.1 ,i found there are two kind , web
guvnor and standalone guvnor.
it seems that there is no diffrence betteen the .war folders in each.
it seems that standalone guvnor only means a web guvnor + a jboss as ?
is there any special requirement on the version of jboss as ?
i found that the jboss as in standalone guvnor folder is jboss 4.2.3.but
when i deployed the .war folder of standalone guvnor into jboss eap
4.3,it throw a exception.
java.lang.NoClassDefFoundError: org/jgroups/MembershipListener

i know that is because short of jgroup.jar,but i can not find this jar
in the standalone guvnor,i goes well.
Why ?
Waiting for reply！ thanks!
best wishes!

Permission Error on drools.packagebuilder.conf
by Gaurav
Hi All,
This is the first time we are merging drools into our application and
getting following error on deploying code to WAS environment.
Permission:
/opt/gen/xxdms/drools.packagebuilder.conf : Access denied
(java.io.FilePermission /opt/gen/xxdms/drools.packagebuilder.conf read)
Code:
org.drools.util.ChainedProperties in
{file:/opt/httpd/root/apps/dms/ibm/ccix-dev-ear/dms.war/WEB-INF/lib/drools-core.jar}
We are not using drools.packagebuilder.conf file directly but it is getting
called internally from drools-core.jar.
I have created an empty drools.packagebuilder.conf file and kept it in
META-INF folder but still getting the same error.
I have already tried putting this entry in was.policy file with read
permission but no luck.
user.home might be coming as /opt/gen/xxdms so I tried changing it to my
local directory on Linux and given read permission for that folder in
was.policy but still no luck.
I have tried all the possible combinations and wasted 5-6 hours.
Could some one please help me resolving this issue.
Thanks,
Gaurav

Difference ruleflow agenda-group
by Bertrand Grottier
Hello,
Can someone explain me the difference between ruleflow and agenda-group ?
I am asking the question because I managed to create a "ruleflow" based on agenda-group.
What is the additionnal value of ruleflow ? Just ease of use or is there anything else ?
Thank you in advance.

Problem With DEFAULT_REFS Table Taking Up A Very Large Amount of Space
by S. McKee
Hello,
I previously asked a question about programmatically creating rules and
then uploading them to Guvnor (
http://n3.nabble.com/Question-About-Programmatically-Creating-Drools-Rule...
). I decided to go ahead with the idea proposed by david_nabble and
upload the rules I created to Guvnor via webdav using sardine.
Unfortunately I have run into a problem where the DEFAULT_REFS table in
the database I am using has become incredibly large; over 27 gigabytes.
Not only that, but the DEFAULT_REFS table consists of only 4 rows of
LOBs. This size was hit after uploading approximately 30 000 - 40 000
rules. If I examine the .brl, each rule is only about 1.1 kilobytes in
size each, so I have only uploaded about 32-42 MB of rules.
Does anyone know what is going on here and/or what direction I could go
in solving this issue?
Thank You,
Scott McKee

Guvnor: Decision Table: DateFormat Problem
by alim
Hey everyone!
I'm using Guvnor and a Decision Table (Spreadsheet) as the rule provider.
I have a column/condition within the decision table that is a method which
takes a date as parameter. My date format in the spreadsheet is dd.mm.yyyy
(e.g. 31.12.2008). Now, once having uploaded the file and viewing the source
(as .drl), the date format is no longer dd.mm.yyyy, but dd/mm/yyyy, which
then leads to a wrong validation within the application.
I know there is this preferences.properties File which can be found under
<path to jboss>\server\default\deploy\drools-guvnor.war\WEB-INF\classes. I
adjusted that with drools.dateformat=dd.MM.yyyy, but it won't have any
effect?!
Is there a possibility to keep the date format as it was in the spreadsheet,
i.e. dd.mm.yyyy? Couldn't find a way to define that anywhere within Guvnor.
Thanks a lot!
