Can some one let me know how to handle exception in Oracle business rules exception( Regular try catch will not compile)

Why aren't you using por_custom_pkg.custom_validate_req_line to add extra validations.
Ensure that profile POR: Enable Requisition Line Customization is set to Yes if you were to use po_custom_pkg for Requisition line validations.
OAF calls por_custom_pkg at various points depending upon the values in Profile Options:-
POR: Enable Req Distribution Customization
POR: Enable Req Header Customization
POR: Enable Requisition Line Customization
Thanks,

Oracle Business Rule Exception during deployment

Hi Experts,
We implemented the OBR(Oracle Business Rules) within CEP and I always encounter a strange behavior. For some reason, I always encounter this error:

After restarting CEP, OBR is running perfectly. I am not sure how to resolve this issue and need your guidance on how to prevent this from happening. My java source source code is below: The initializeDecisionEngine is called only once. My input to OBR is a java.util.Map(this is a requirement and can't do anything about it).
private String rulesPath;
private RuleDictionary ruleDictionary;
private DecisionPointInstance decisionPointInstance;
private String decisionFunctionName = "decisionFunctionName";
private void initializeDecisionEngine() {
 try {
 if (rulesPath == null) {
 return;
 if (decisionPointInstance == null) {
 ruleDictionary = this.loadRuleDictionary(rulesPath);
 DecisionPoint decisionPoint = new DecisionPointBuilder().with(
 decisionFunctionName).with(ruleDictionary).build();
 decisionPointInstance = decisionPoint.getInstance();
 System.out.println("INIT() OUT");
 } catch (SDKException e) {
 // TODO Auto-generated catch block
 e.printStackTrace();
private RuleDictionary loadRuleDictionary(String path) {
 System.out.println("loading dictionary from path: " + path);
 RuleDictionary dict = null;
 Reader reader = null;
 try {
 reader = new FileReader(new File(path));
dict = RuleDictionary.readDictionary(reader, new DecisionPointDictionaryFinder(null));
 List<SDKWarning> warnings = new ArrayList<SDKWarning>();
 dict.update(warnings);
 if (warnings.size() > 0) {
 log.error("Validation warnings: " + warnings);
 } catch (SDKException e) {
 log.error(e);
 } catch (FileNotFoundException e) {
 log.error(e);
 } catch (IOException e) {
 } finally {
 if (reader != null) {
 try {
 reader.close();
 } catch (IOException ioe) {
 ioe.printStackTrace();
 return dict;
private executeOBRRule(){
Map<String, String> mapEntry = new HashMap<String, String>();
mapEntry.put("column1", "value1");
mapEntry.put("column2", "value2");
mapEntry.put("column3", "value3");
if (decisionPointInstance != null) {
 decisionPointInstance.clearInputs();
 // decisionPointInstance.
 List<Object> list = new ArrayList<Object>();
 list.add(mapEntry); <--- Adding the map to a list since it is the only allowed input for OBR, or is there any other way other than list? -->
 decisionPointInstance.setInputs(list);
Object obj = decisionPointInstance.invoke(); <<<<<< this is where the exception is raised.
My question is that why is the exception is being raised and sometimes it is not. My only resolution is to restart CEP server. Am I missing something? My obr rule file is ok since it does not display any error during compilation. If you can guide me to the correct path, I will really appreciate it.

Russel

Is this problem resolved?
If so it would be greatly helpful if you could provide the solution.

Query on handling else condition in Oracle Business Rules.

Hi all.
I am working on Jdeveloper 11.1.1.1.0 Business Rules. While creating rules... i am able to write if conditions around the facts and attributes and also replicate the same using decision tables and is able to derive the action.
My Question is.. can i write an else condition which should be executed when none of the if condition are matched. If we can how... Instead of else condition, is there any way that we can initialize the facts and attributes to be derived to a default value.
Please help me guys in this... If this is not the right foru,... please redirect me to the correct one.. coz i couldnt find a forum for oracle business rules..

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.

Syntax errors in Oracle Business Rules carrental ruleset

Hi,
I'm using Oracle Business Rules Rule Author on Windows, version 10.1.3.0.0.
I'm working with the OTN carrental sample. If i load the supplied file-based repository CarRepository from the %HOWTO_HOME%/dict directory, navigate to the RL tab -> Generate RL-code and select the 'Check RL-Syntax' button I always get the same error message:
Error:'5}' is undefined at line ... column ... in [DM or vehicleRent]
If I navigate to 'Test Rulesets' i get the same error, no matter what testfunction i use with the vehicleRent ruleset.
When i test the sample with the supplied java code i don't get any errors.
However, if I follow the steps in chapter 2 (javaFact) or 4 (XMLFact) of the Business Rules user guide and setup everything from scratch for a filebased repository i get the same error at runtime.
I based the filebased repository on the supplied emptyrepository file.
Seems to make no difference whether I use a filebased or a webdav repository.
any help on this would be appreciated.
Rob

There are two problems here. First, there is a bug that causes this error string to be displayed incorrectly when using the RuleAuthor in any browser language other than English. If you change the browser language to English, you should see:

A syntax error is found. 
Error:'carrental.Driver' is undefined at line 4 column 14 in DM

The cause of this problem is that carrental.Driver class is not in the classpath for Rule Author. This isn't covered in the how-to. See section 3.10 in the Oracle® Business Rules Users Guide (B15986-01) (available from here).

From this doc:

Create a rule set you want to test. If the data model includes any Java classes, the
Java classes must be included in the OC4J classpath. The easiest way to do this is
to put the JAR files in the following directory, then restart OC4J:
$ORACLE_HOME/j2ee/home/applications/ruleauthor/lib

or add it as a shared library using EM (specific instructions follow in the doc) and then add that shared library to RuleAuthor.

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.

Validate ADF UI field as per Oracle Business Rules

Hi ,
I have a requirement where the relationship between the various data fields are defined in Oracle Business Rule 11g inside BPM Project.I need to call these rules on ADF screens for data population.
Eg, If there are two fields on ADF UI,field1 and fiedl2.
Possible combinations of the two field are:
Field1 Field2
A B
C D
E null
The rules are part of OBPM 11g project as customer can change the rules through composer at run time as per business need.
How can i achieve this requirement.Please help urgent.
Regards...

Hi Daniel
Lets say i have two attribute 'Product Code' and 'Department id'.The relationship between the two attributes is defined in Oracle Business Rule.
eg.
If Product Code is '111' then Department is 'Finance'
If Product Code is '222' then Department is 'Inventory'
The values for each of the attribute is defined in a database
Product Code Table
Value Description
111 SalaryAllowance
222 Current Stock
Department Table
Value Description
Finance Handles Payroll
Inventory Handles Packaging
I am displaying these two attribute on the ADF UI as dropdowns. If I select '111' from the product code dropdown then the value in Department dropdown should automatically be set as 'Finance'.I need to trigger the validation/relationship between the attributes from business rules.
The reason for keeping the relationship in rules is because business wants to change these relationships at run time.
Hope the scenario is clear to you.
Regards...

Oracle Business Rules.Bucket set

Hi all,
#1 How to add list of values into bucket set from a database and excel?
say for example if i want to add 100,200,300 in a bucket set where these values are populated from a database table or Excel.
how do i do that?
Any suggestions.
Thanks,

Edited by: 965698 on Oct 16, 2012 1:07 PM

Hi Raju,
You could investigate the use of the Java API of Oracle Business Rules, see http://docs.oracle.com/cd/E23943_01/apirefs.1111/e10663/toc.htm. It contains classes and methods to interact with bucket sets in an automated fashion.

Oracle Business Rule Engine

Hello Everyone,
I am using Oracle Business Rule in an application. I want to know that is it possible to call a rule
set from another rule file.
Suppose there are two rule files RuleFile1 and RuleFile2.
We have invoked RuleFile1 the by any how can we invoke the rule set from RUleFile2.
thanks
saleem

Yes, it is.
In RuleFile2, just add
include file:RuleFile1.rl;
Then, all of the elements in RuleFile1.rl can be referenced from RuleFile2. Since RL is interpreted, the file must be available at runtime.

Problem in mapping Task payload parameters to Oracle Business Rules facts

Hi all,
We are using complex types from our project XSDs inside the Human Task payload. We intend to use these Human Task payload parameters to build routing rules using the Oracle Business Rules interface. Our observation is that when the complexity of these complex types increase, the business rules editor does not show these as facts that can be used in formulating rules.
Has anybody faced such a problem before. Any help is appreciated.
We are using the following link to add routing rules –
http://docs.oracle.com/cd/E25054_01/dev.1111/e10224/bp_decision.htm
Version details :
ADF Business Components     11.1.1.60.13
Java(TM) Platform     1.6.0_29
Oracle IDE     11.1.1.5.37.60.13
SOA Composite Editor     11.1.1.5.0.01.74
Thanks,
Yamini.

Problem solved. There was an element in the xml schema that had nillable = true. Because of this the XML Fact for that element would no longer be available in the BPEL Process. Removing the nillable and generating the XML Facts again solved the missing variable problem.
