JHeadstart, Oracle Business Rules and BPEL Process Manager

Dear JHeadstart Team,
I have some questions regarding integration of JHeadstart and Oracle Business Rules and Oracle BPEL Process Manager. As a matter of fact I don't have any work expriences with these tools so my questions may not be good and precise.
1- Using a business rule engine can dramatically increase speed of development and ease of maintenance.I had a very good exprience in using JHeadstart and Headstart in the past but I wanted to know if it is possible to use Oracle Business Rules in conjunction with the JHeadstart ? If so, What steps should be taken? Is there any known issue about this integration? Does Oracle Business Rules have any interference with JHeadstart or it is only used in model layer during insert,update,delete?
2- Is it possible to develope a system based on oracle work flow engine (Oracle BPEL Process Manager) using JHeadstart ? If so, What steps should be taken and how the changes in the flow of work would by applyed in a system developed by JHeadstart. Is there any known issue about this integration?
Any help,link to documents or general guidelines would be highly appreciated.
Thanks in advance,
Navid

Couple of things I would like to add, are the following.
In the context of an ADF application usage of Oracle Business Rules most likely is in the business logic layer, but mind that it does not need to be restricted to that.
Oracle Business Rules takes so called 'facts' as input, evaluates some rules based on that and change those facts or return some result. That might be checking a business rule as defined in the JHeadstart Developers Guide. But it might also return some value that is used in a navigation rule.
Think about a page flow where after page A normally page C is presentend, but in case of some situation (like a customer ordered something and you want to present some special offering based on that) you want page B presented in between (i.e. A -> B -> C). Oracle Rules could be used to determine this page flow. This would be an example of using it in the controller layer (probably in combination with using facts that come from the model layer).
Another remark that I would like to make, is that in my opinion it does not make much sense to use Oracle Rules for business rules that logically more or less are part of your data model (like end date must be on or after begin date). You typically use Oracle Rules to implement business rules that are of a volatile nature, meaning that day-to-day business may require a change of the rules. One example is the navigation case that I mentioned before. Another (typical) example would be a rule that defines when a customer is a Gold customer.

Unable to integarte Oracle business rules with BPEL

hi'
I am unable to integrate Business rules with BPEL, I am using JDeveloper to do this.
I have successfully made a connection to rule repository and using decision service in synchronous BPEL process.
In the decision service wizard step 1 of 2
1.) Selected 'Execute Ruleset' in Invocation pattern
2.) Selected rules set which I have cretead before.
the problem is coming when nothing is geting displayed in the
window below for Fact name, assert name, watch fact.
please help me why Fact name, assert name, watch fact are not coming.
thanks
Yatan

Thanks Anirudh,
Do I need to make some changes in the java classes or in the XSD file which I am importing while creating new BPEL process
I am importing the same XSD file in input and output, actually I am updating the database in the BPEL process so I am taking the
input from the payload and updating the DB.
Do I need to make two different <complexType name="updatingDB"> and <complexType name="businessrules">in the XSD
if you have some example which shows the Integration of BPEL and Business rules
with Java facts please share it with me.
thanks
Yatan

What is the difference between WORKFLOW API and BPEL PROCESS MANAGER API

Hi,
I am using BPEL process manager and would like to know the correct api set.
I found the workflow api which appears to be part of the oracle workflow.
is workflow api and oracle BPEL process manager two seperate products? --- Pls confirm/deny.

Hi me_sun, me_oracle :)
The bpel api can be found here
http://download.oracle.com/docs/cd/B31017_01/integrate.1013/b28986/toc.htm
workflow found here
http://download.oracle.com/docs/cd/E12483_01/integrate.1013/b28985/toc.htm
when us install BPEL you do get BPELs human workflow component. This is different to the Oracle Oracle workflow which was based on the database and PL/SQL.
cheers

Business Rules and BPEL integration

hi
can u provide me information on how to integrate Business Rules with BPEL. do provide me any documents related to this, if any.

Hi,
In the new 10.1.3 release (scheduled to hit the streets this summer) Oracle provides business rules support in the BPEL product.
Supported in 10.1.3 are Ilog Jrules as well as Oracle's own business rules engine that will be contained in the package.
More info on new features can be found in a recent web seminar for which the replay can be obtained here: http://www.oracle.com/technology/products/ias/bpel/htdocs/webinars.html.

Oracle business rules and backchaining

Hi,
Does Oracle Business Rules support backchaining, as Jess does?
Cheers,

No, not in 10.1.3 and not in the first planned 11 release. It is on the list of candidate features for future releases.

Creating simple Business Rules in BPEL process

Hi,
I have an environment consisting of SOA Suite 11g running on Weblogic Server. I'm using JDeveloper 11g for development.
Scenario
I have a BPEL process which starts off by polling a DB table and I then assign the input to a Recieve activity's InputVariable. I have a 'Number' column which will contain a number between 1 and 3. I then require Business Rules (BR) to be set up which read this value, and based on the number, assign a 'Name' string (which is to be the output variable from the business rules) to be used later on in BPEL process.
Problem - I have followed the basic tutorials available in order to set up the business rules, but am getting numerous errors. Firstly, I sometimes find that my input/output variables created during setup of BR component and the XSD based on this, does not have XML Faces automatically created for it (therefore have to create it myself by clicking on the + button and doing this for each element of XSD). When I do get this working, I then double-click on my Business Rules activity in my BPEL process, only to find that the input/output variables here no longer are assignable to my BR input/output variables as I get the following error "Exception: Problem Building Schema!".
I am not sure why this is, but suspect that my XSD (which is very simple anyway) or the setup steps I follow to define the link to my XSD, are wrong.
I have taken the following steps so far:
1. Create empty BPEL process
2. Set up polling adapter to poll DB table
3. Create Receive activity and assigned polled input to created variable
4. Add Business Rules component to composite and set up and create dictionary here. Also set up inputs/outputs to be in form of my XSD elements.
5. Add Business Rules component to my BPEL process and configure this to include input/output variables (*This is where error occurs*)
6. Go back to .rules component in composite to define rule and define rule
Upon deployment, I get many errors most of which pertain to "Unresolved XML element... make sure XML element +xxxxx+ is defined in one of WSDL's that are referenced by the deployment descriptor."
I have only imported a simple XSD containing two elements to this project. The other XSD is the one of my polling adapter. I've not created any input/output variables for the overall BPEL process as didn't think I was required to.
Can you please help in getting this process doing the simple activities described at the top.
I appreciate your help.

Hi,
Create a project with BPEL composite
Now drag a business rule
Now create input variable of type ur requestelement
and output variable of type response element
Now in rules designer page take decision table
and then craete a condition (inputelement.input > 1000) and in the rule select true
now create another rule select false
Npw create an action with assertion and select the parameterized box there
now in designer page for first rule assign some value (say 500) and for second rule some value(100)
Now in bpel u have to assign a value to input var of BR
Deploy the process
If u supply 10000 u will get 500
if u supply 100 u will get 100
In the same way u can do by using If-Then
You can use facts and bucketsets according to ur requirement

How to make BPEL process work with Oracle Business Rules

Hi
I know that we can use business rules in BPEL process as decision services.
But how should I do in real development? Are there any samples or tutorials that explain how to do that in details on otn or somewhere?
Could somebody help?
Thanks a lot
Peter

Thanks a million.
But I have an other problem now.
That is my JDevelper has no Decision service activity. And I saw the list label name is BPEL Extension Activities. But my JDev has no such a list item. What should I do?
Hope somebody could help me!
Thanks

Problem with balance carry forward business rule and automatic adjustments

Hi All,
I faced with issue when run BCF business rule and consolidation process. According sap courses BPC440 members with A(automatic adjustments) type should carry forward automatically, and I(imputable), M (adjustments) members should carry forwarded by bcf business rule.
When I set up my BCF business rule I use property "Category_for_ope" in Category dimension. But this rule not work properly, then I use notes:
1784365 - Category_for_ope property should not effect Consolidation.
1902677 - The property category_for_ope shall work for consolidation
After applying those notes, system work as I aspect. After i run consolidation first time system carry forward my automatic adjustment from Category "Expected" to "PLAN_Y0" and this is correct!!!. But when i run consolidation process second and third time system duplicated automatic adjustments in Category "PLAN_Y0".
Someone can help me with this Issue?
And sorry for my english

Hi,
Can you try as follows :
*RUN_PROGRAM COPYOPENING
CATEGORY = %C_CATEGORY_SET%
CURRENCY = %RPTCURRENCY_SET%
TID_RA = %TIME_SET%
*ENDRUN_PROGRAM
hope it helps...

Jdev version compatible with BPEL Process Manager

Hi,
I would like to know if there is any compatibility issues between the versions of JDev and BPEL Process Manager. (Please note we have only BPEL Process Manager and not the complete SOA suite).
Thanks.

The documentation would mention to use same versions, but may be not be the exact justification. However, here it goes : mostly for testcases related to humanworkflows/custom worklist applications.

Oracle BPEL Process Manager- latest API and developer's documentation.

This is regarding Oracle BPEL Process Manager.
I'm planning to integrate the same, for review or prototype purpose, so need to know about the API documentation and developer's guide if available.
The API documentation available seems to be inadequate as it does not document the collaxa APIs (for example) so need to know any documentation available to integrate Oracle BPEL Process Manager as workflow engine.
What I'm looking for is the API documentation, developers guide for integrating Oracle BPEL Process Manager APIs etc.
Developer's guide to manage the development of business process lifecycle of deploying, executing and managing business processes programmatically, using the Oracle BPEL Process Manager, v2.0.11 API Specification.

For the Java API, please take a look at the Java Doc in c:\orabpel\docs. You can also learn about those API by looking at the implementation of the BPEL console (given that the BPEL console is built mostly on the public API of the engine. There are also a few tutorials (02.Invoking A BPEL Process) which highlight how one can invoke a BPEL process through the Java API both locally and remotely).

Diff Between Oracle BPM Studio and Oracle BPEL Process Manager

1)What is the difference between Oracle BPM Studio and Oracle BPEL Process Manager?
2)What is the connection between Oracle BPM Studio and Oracle BPEL Process Manager?

Hi,
As of today you should install SOA Suite 11g
Fr this you will need to install Database (for development you can use XE)
Run RCU utility to crete DB schemas for SOA Suite.
Install Weblogic server
Install SOA Suite as an option to Weblogic
Create SOA Domain.
It is physically possible to do it in 2GB but is far better on 3 - 4GB
You can consider installing DB on different machine.

Can I use Oracle BPEL process manager with other AS and DB

Can we user oracle bpel process manager with jboss application server and postgresql database.. is it possible..
and what will be the price.. per licencse when i go to just purchase Oracle BPEL process manager

MAke sure you have not set ANY environment variable related to Oracle / BEA / Java / LD_library path. Use the following script to unset / set the initial settings:
#!/bin/sh
unset ORACLE_BASE ORACLE_HOME ORACLE_SID ORACLE_TERM
unset LD_LIBRARY_PATH LD_LIBRARY_PATH_64
unset CLASSPATH JAVA_HOME
export PATH=.:/usr/sbin:/usr/bin:/usr/local/bin:/opt/VRTS/bin
export BEA_HOME=/appl/oracle/products/9.2/weblogic

Oracle BPEL Process Manager 10.1.3.x sensors and Oracle BAM Server 11g TP4

In Oracle Fusion Middleware Developers Guide for Oracle SOA Suite in section 42.5 there is the next:
"You can also use Oracle BPEL Process Manager 10.1.3.1 sensor actions to publish sensor data as data objects on Oracle BAM Server 11g"
Is it really possible?
