Creating a Business Rule in BPEL

“A Business Rule is a rule that defines or constrains some aspect of the business. His statement is determined as true or false. Business Rules seek to determine the business structure or to control or influence business behavior. “

“http://en.wikipedia.org/wiki/Business_rule”

Here we create a simple Business Rule that will define as our input parameter if it is a person PHYSICAL(FISICA) type or type LEGAL(JURIDICA)

First of all it is interesting that you make sure your COMPOSER is active on your domain, to see this Post: Enabling SOA Composer in Oracle SOA Suite 11g

After that, we will create a project called BusinessRuleBpel

Click File >> New

Will open a screen like below:

Then select Generic Project

Project Name BusinessRuleBpel place and select the SOA Technologies Project name and click the small arrow > to the name go right and be as below:

Click Next and then Finish, leaving the Composite Template in Empty Composite

Now we create an empty project will create a BPEL

Now right click Componets > Insert > BPEL Process

Click BPEL 2.0 Specification

In place name BusinessRuleBPELProcess

In Template select Synchronous BPEL Process and click OK

Let selected option Expose as a service SOAP, as this will be responsible for creating a WSDL and XSD default which will change for our tests.

Ready, it should look like this:

Open your BusinessRuleBPELProcess.bpel

Among the receiveInput and replyOutput drag a Business Rule component as follows:

Rename the RULE1 to TipoPessoaRule, you just double-click on the name.

Double-click on the TipoPessoaRule box and click the plus sign + beside Dictionary

On the next screen we set the name of our Rule, and the input parameters (input) and output (output).

In Name: TipoPessoaRules place and click the plus sign + then on Add input Variable

Now click the second box Variables in Process and click the plus sign +

In Name: Enter TipoPessoa and click the magnifying glass

Project Schema Files, select the process option and click OK

Then we initialize our Rule with our input

Then, click the Initialize tab and select the option payload within inputVariable as follows:

Note that in XPath will as $inputVariable.payload

Leave Selected TipoPessoa the option and click OK

Now again on the screen below and click the + and now click Add OutputVariable

Click Variables and click the plus sign +

Name Mensagem in place and click the magnifying glass

Project Schema Files select the processResponse option and click OK

Click OK again

In the screen below select the Mensagem name and click OK

Ready, your screen should be as follows, see that now define our input and output, now click OK

After clicking OK was then created our TipoPessoaRules.rules rule as below, then click Create Rule to define our rules by IF / THEN

We will take the appropriate names 🙂

Place names as follows, noting that to rename just click on the name and give a ENTER

Ruleset1 – Rename to TipoPessoaRuleset
Rule1 – Rename to PessoaFisicaRule

It should look like this:

Now let’s define our terms:

Just below the IF click <insert test> and will appear automatically <operand> == <operand>

Click the first <operand> and select the option TipoPessoa >> input

Now in the second <operand> put double quotes “PF“ and press ENTER

In THEN click <Insert Action> and select assert new

In <target> select Mensagem

In <edit properties> by clicking the following screen will appear, then the Value tab put double quotes “TIPO PESSOA FISICA“, take a ENTER return and click OK
