Business rules in Java code

Hi,
I am newbie to Java development.
I have a bunch of Java classes. I need to list out the java classes, which has business rules in it.
Please share your views on this issue to proceed further.
Thanks,
Appu..

Read this: http://en.wikipedia.org/wiki/Business_rules
It's not exactly rocket surgery... but sometimes it's none too clear what-is and what-is-not exactly a "business rule".... if in doubt it's a business rule.
For instance:
Q: Does an xsd contain business rules?
A: HellYes.

Error while saving Business Rule EAS Java

Hi there all, I get the following errror when saving a business rule that actually was working fine just yesterday. Something tells me it's about network issues but i'll appreciate if anyone got the same and how to solve this. Thanks.
Error while sending command to HBR Server running within the EAS server.
Detail:com.hyperion.hbr.excp.DatabaseException.<init>(java.lang.String, [Ljava.lang.Object;, com.hyperion.hbr.excp.ExceptionSeverity, java.lang.Throwable)

Thanks for your fast reply.
This error is occurring in our development environment as well. Production is fine.
I had the users get out of the system last night and I tried restarting services and eventually restarting each server but nothing has cleared the error yet.

Business Rules error-java.lang.NoClassDefFoundError: com/hyperion/hbr/core/

Hey I recently applied the 11.1.1.3.04 service fix for calc mgr/planning which involved a few file changes for EAS as well.
I patched and re-deployed calc mgr/planning/eas without any issues in DEV
When I patched prod, and then redeployed the web servers, business rules is now failing.
This error is in the planning log:
java.lang.NoClassDefFoundError: com/hyperion/hbr/core/HBRThinServer
and this error is in EAS log when I login to EAS:
ExecuteThread: '5' for queue: 'weblogic.kernel.Default (self-tuning)' com.hyperion.hbr.db.DBTable - Error while creating Repository object. Please make sure your HBR Configuration is correct.
ExecuteThread: '5' for queue: 'weblogic.kernel.Default (self-tuning)' com.hyperion.hbr.core.PluginDataManager - Error creating PluginDataManager. Please check your log file for details on what caused this error.
Anyone run into this issue and have any advice how to solve it? I also opened an issue with Oracle
THanks
Jeff

Thanks for the advice Nick.
I decided to redeploy EAS app server again, but this time also re-register the database. the register database step was not needed when I patched dev or test, perhaps because in dev and test planning and eas were on the same server. In prod, eas and planning are on different servers.
so after registering and re-using the existing tables so that I wouldn't lose my rules, the app deployed without any errors in the logs and all my business rule problems have been resolved.
Thanks
Jeff

Business Rules and Business Intelligence in Java CAPS 6

Dear All,
I have two doubts.
1. Is there any way to add a Business Rule component and write Business rules in Java CAPS 6? As you may know, this is possible through eInsight in JCAPS 5.1.2.
Is this feature readily available in Java CAPS 6? If yes, can you please let me know where it is?
2. Are there any Business Intelligence tools in Java CAPS 6? If yes, what all things we can do with that?
With warm regards,
Sree.

Sree,
It sounds like you are talking about a Rules Engine - not necessarily a Business Process Manager..
Also it depends on what you mean with "rule".
The approach I mentioned previously about IDS-Scheer's Aris meant that a Business Process is modelled in Aris - that is the focus is on the business developer. However the actual implementation of the business process would need to be developed by a Developer. Likewise if a change is performed in the Business Process it would need to be retrofit into CAPS for implementation.
When it comes to Rules Engines, Sun has a partnership with Yasu. Yasu have implemented their Rules Engine as a JBI SE, which would work with the JBI part of CAPS6, OpenESB or Glassfish ESB. More infor can be found at:: http://www.businesswireindia.com/PressRelease.asp?b2mid=12735.
I am not aware of any explicit "business intelligence" functionality in the CAPS -suite.. Looking at the Jasper Suite however, the CAPS suite does have ETL functionality, no built in reporting, but a Master Data Management System (http://developers.sun.com/docs/javacaps/products/sun-mdm-suite.jsp), which I belive could assist decently when it comes to data quality and data source prioritization concerns.
When it comes to Jaspersoft there are examples of how to build a CAPS6 JBI BAM solution using Jaspersoft's IReport (Netbeans Plugin), which in turn uses JasperReports.

How to create business rules from Jdeveloper 10.1.3.1.0

Dear Experts
Can I able to create Oracle Business rules from My JDeveloper 10.1.3.1.0.

Why these features are missing, to get those additional features what I have to do.. ? Please suggest your best for me.
Also Is it possible to build business rules from java sdk & from rule author..? If so means what is the difference, which one is having advantage.

Should I do this with Java Code or Stored Procs ? (for best performance)

Hi All,
I need to decide where should I implement my business logic, in Java code or Stored procs.
Here is the requirement :
- One Order has 70 products (Order_Table )
- Can be duplicate products, so I have to do summarize / grouping by product
- For every product, I have to check, if it is entitled for a Bonus product, then I have to Insert one to Bonus_Table.
- This is done when/after the transaction is SAVED (COMMIT)
The question is, which one has better PERFORMANCE :
(1) Create a rowsetIterator on the Order details (70 products) and call a stored procedure to do the logic for every single product (so that the Insert to Bonus_Table done in stored proc). means the stored proc will be called 70 times.
OR
(2) After the transaction is COMMITted, call the stored procs ONCE to do the logic for all the products at once.
OR
(3) I do all the logic with Java Code within ADF
Given the requirement above, which approach is most efficient / best performance ?
Thank you very much,
xtanto

Problem with this is that you ask 100 people and you probably get 100 different answers. ;o)
Many would say that you push as much business logic into the database with your data; others might say you only put data in your database and your business logic is kept on the application server.
In reality your would probably have a mix of both and your decision would probably be influenced by your own background ...
Can't be more precise than that.

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

Error code returned if the business rules not executed

Recently we found that some Hyperion business rules are not executed during the daily batch file but no error code was returned.
Is there any method to force the return of error code so that we can check the batch result more easier?
Thanks a lot!

For information, we are using the batch file under EAS console directory of Essbase:
\Hyperion\products\Essbase\eas\console\bin\CmdLnLauncher.bat
@echo off
set CPATH=..\lib\CmdLnLauncher.jar
set CPATH=%CPATH%;..\lib\easclientplugin.jar

Java.util.ConcurrentModificationException when mapping the business rule?

Hi,
In our project there are two BP's.One is Main BP and other one is Sub BP.I would invoke the SubBP from Main BP.So Inside main Bp there is a JCD component and output of this component would be input of Sub BP.The main BP will be
Start=====>JCD===>SubBP===>End.
So when I add business rule between JCD and SubBP and Save,I am getting java.util.ConcurrentModificationException...But the mapping are seems like fine..
Please update me if any of you knows the solution.
Thanks,
Renga.S.

DB Call from Oracle Business Rule +Java Method call from OBR

Hi,
1.We have a requirement in project where we need to make DB Call from Business rule.
We are using ORACLE SOA11g.
Is this possible.Any pointers on this will be helpfull.
2.Can we call java method from Oracle Business Rule.If so pls suggest how it can be done.
Thanks In Advance,
Oracle SOA User

You can implement java class to make database updates using JDBC. You can add Java class as fact in business rules and invoke methods as actions of the business rules.
Hope this will help.

Substitution rule for Business place and section code

Hello Friends,
We have a business place and a section code. I want to write a substituion rule for vendor invoice for business place and section code.
When i see in header, i am not find BUPLA and SECCO in header. I am finding them in line item. How do i get these fields in header segment. I tried substution rule in line item, but the tds is not deducted.
Thanks
SK

hi SK,
i am not understand your problem. Previously i face one problem regarding business place and section code. While booking invoices and advance payments the user forgets to specify business place or section code and some times he specifys wrong business place also. Basing on business place or section code we cant restrict the users because there is no authorisation object.
i created one validation that if my business area is 1000. then substitute the business place field with section code.
we have business place individual business area wise so i created this substitution.

Sankar

Complex "validation rule" using Java Bean code

Hi,
I have never used validation rules with jdeveloper, but i need a complex validation rule of one column of my table.
Can i put a "validation rule" on an attibute of a view object, or on a column of a table, that use Bean code ?
My column must contain different values depending of the other columns of the table, so i think i can't do this without java code...
I tried to doubleClick on the column to create a validator, but I have put a "Print" inside, and seen that it is executes lots of times, but I want to execute the validation only when the value of the column change !
How can I do this ? What do i need to use ?
Regards,
Trigger

I have use John's solution, it works well !
Sorry vinod_t_krishnan i am good with java but i don't know how to use well EL Expressions so I did not try your method...
The code if so is interested...
