homepage for the OSB cookbook and download the ZIP file in the ZIP file is a PDF document named Oracle Service Bus 11g is a scalable SOA integration platform that delivers an efficient, standards-based infrastructure for high-volume, mission critical SOA environments. Oracle Service Bus is a core component in the Oracle SOA Suite as a backbone for SOA messaging. November Documentation for developers that describes how to use the. Oracle Service Bus Console and Oracle JDeveloper to create and configure proxy.

Give folder as WSDLs as shown below. Changing JMS Transport message headers and properties at runtime. Now your CustomerPSPipeline message flow should look like below. Click Activate and confirm the session so that your changes will be effective. Once response is received. Using Email Transport to send e-mail.

So you can always create placeholder in your template. Error handling is another aspect of message flow where you should follow similar approach for different Proxy Services that you create.

First things is. You can come up with a WSDL or can get it from here. You will finish this ErrorHandler stage later in Error Handling section. Delete and Merge operations as mentioned in business requirements section that can be used for creating Proxy Service. Click Search icon to bring up Resource Chooser and select pipeline template created in previous section. Choose CustomerPS.

Verify that WSDL and binding is being selected. These changes would resolve the errors in Proxy Service and observe all red marks are gone. So service consumers can access your proxy service using URL http: Since a few of the properties which are mandatory in concrete pipelines but not mentioned in template.

Also observe that new tab is opened showing CustomerPSPipeline. Observe that your pipeline had inherited all placeholders. Open CustomerPS and navigate to Transport configuration as shown below. Now your Service Bus Overview Editor should look like below. For more information refer to this link. So in this section. Left swim lane is for services providing an entry point to application so limited to Proxy Services. In this section. As observed in previous section.

Creating Message Flow In 12c. Middle swim lane is for components providing routing and transformation so limited to Pipelines and Split-joins.

Right swim lane is for references providing communication with actual service providers so limited to Business Services or Proxy Services. Click icon to add 4 more additional branches and select UpdateCustomer. Create Customer In this section. Validating Payload In this section. In Properties tab of Validate activity. Now your message flow should look like below. Drag or shuttle Customer element into Expression field as shown below and click OK.

Now you can observe all red marks are no longer visible for CreateCustomer branch as you set required properties. To validate Email element. For Location property bring up expression editor by clicking icon.

Now your properties tab for Validate activity should look like below. Now your Validation stage should look like below.


You can remove Else branch by selecting Delete on right click. The domain names PropertyName represent configurable properties and PropertyValue represents property values respectively.

Validating Address In this section. For current scenario. This way. Using DVM. Remember you need to create a session before modifying anything. Set Variable property as ConfigVar.

Bring up expression builder for Value property and give expression as shown below. Now your Properties tab should look like below. Address Validation business service should be invoked only when the value of this configuration property 'Y'. Routing node always depicts end of message flow so you can't place any activities after Routing node.

Routing and Service Callout are used for Synchronous where as Publish activity is used for one-way communication. Routing and Publish activities to route incoming request to an appropriate business service. Hence we use Service Callout for all intermediate service calls in pipeline.

As mentioned earlier. Service Bus provides Service Callout. To achieve this. Since you are using the 'Configure Soap Body' option. Next task is transforming the received payload to the structure expected by address validation business service. One of the added features in 12c is JDeveloper has complete design time support for XQuery as well. First we will get hands-on in using XQuery files so let us start creating one serving your purpose.

Click browse icon and select Customer element in CustomerPS. You can map the fields by connecting source element to target element.

Click OK thrice to bring up transformation editor. Now click pencil icon for Target to bring up Function Result Type window. Do the initial mapping of attributes as shown below.

Address Validation service expects address lines with '. Click List of variables button highlighted above to bring Edit Variable window and select the options as shown below so that sample input will be generated automatically. You can also verify sample source and target files created in your XQueries folder.

To use this XQuery mapping. Click Run and verify the mapping is working as expected. Click OK and use following steps to set value for Binding property. In expression builder.

Bring up expression builder for Value property and give the expression as shown below. Now use another Assign activity to enclose the payload in soap-env: Body element. Once response is received. To register new namespace.

Here you need to give the namespace used by response schema of address validation service. The red line denotes namespace alias addr is not a valid one. Click OK and observe red line is no longer visible. Defaulting In this section, you will default CustomerType element if the value is not sent. Drag If-Then activity into this stage from Flow Control and give condition as shown below. Alternatively, you can select fn: Set other properties as shown below so that CustomerType element will be inserted in body context variable after DOB element in request payload.

Instead of hard-coding these values in your message flow, you can use Service Account feature provided by Service Bus to store credentials which can be referenced in message flow using XQuery function.

The XQuery function fn-bea: UsernamePasswordCredential xmlns: In this case. And in Properties tab. Choosing the option 'Configure Payload Document' allows you to send request and receive response payload without soap-env: Body tag. This function returns following XML fragment.

Now your properties window should be shown like below. If you observe red lines. Drag another Assign activity and set properties as given below to populate payload for business service. Routing In this section. Complete Source parameter selection as shown below and you can refer to previous sections for actual navigation steps. Next task is transforming the received payload to the structure expected by CustomerService business service.

Complete Target selection as shown below and you can refer to previous sections for actual navigation steps. Click OK and do initial mappings as shown below. Go to Source tab and do modifications as highlighted below. Set other properties as shown below. Set condition as shown below and add namespace alias cust with namespace urn: The actual Fault Response will be sent from Proxy Service Error Handler that will be discussed later in this tutorial. Drag Assign activity into If branch from Message Processing and set properties as shown below to store unsuccessful response in faultVar variable.

Complete Source parameters selection as shown below and you can refer to previous sections for actual navigation steps.

Bring up expression builder for Value property and select above XQuery map as shown below.

Click OK and finish the mapping as shown below. CustomerType element Validation: Email element Validation: Testing Deploy both projects or run Pipeline directly as shown in Deploying and Testing section.

You can also run Proxy Service but you will not observe any Flow Trace. Run your pipeline with sample payloads given here and observe Flow Trace and Variables as shown below. Positive Case. Status E in business service response: ValidateAddress configuration property value as N: Negative Case. Email element validation has to be done only when it's sent in request.

Give the following expression in top-level If-Then condition to find whether Email element is available and length is greater than zero. Use Actions placeholder in Validation stage to do this. Update Customer In this section. Since we have discussed each and every step in detail and extensive manner in previous sections. Since this is Update operation. You can also do the Address Validation similar to CreateCustomer operation.

But we are not going to discuss this again in this section. Retain the default selection and click Browse to select primary source element as shown below.

And click Browse for Select Schema and select the target element as shown below. Now click Browse for Target to bring up Select Schema screen. Since we are doing update of customer information. You can achieve this behavior automatically in XSL Map editor by setting a preference.

Go back to XSL Map editor and finish the initial mapping by mapping respective source and target elements as shown below. Also concatenate State. Observe that xsl: Click on concat functions and modify them as shown below by adding new elements. Now go to Source for XSL map. You can also modify source xml and retest your XSL map again. Click OK and observe both source and target xml files get created.

Finish Response Action in Routing similar to CreateCustomer as response structure of business service is same for all the operations. CustomerType element validation:. Delete Customer In this section.

Service Bus 12c – A Hands-on Tutorial | Siva's Blog

Since this is Delete operation. Both source and targets have single element CustomerID and finish mapping as shown below. Now your Routing node should look like below.

No CustomerID element: No value for CustomerID: As per business requirements. Merge Customer In this section. So you should reuse the existing message flow created for Create and Update customer operations. The message flow should perform following: This operation returns Y for existing customer and N otherwise.

So drag If-Then activity from Flow Control and set condition as shown below. You can verify customer existence only when CustomerID is present in input payload. Drag a Service Callout into If branch from Communication. Set other properties as shown below and choose 'Configure Payload Document' option. Give verifyCustReq as value for Variable property. If your requirement is just within Service Bus project you can create Pipeline having common message flow and call from main Pipeline or ProxyService.

To overcome this. And you already completed these actions as part of CreateCustomer and UpdateCustomer operational branches. If you require this across projects you can create Proxy Service having common message flow with local transport. You can also verify new pipeline got created in Pipelines folder. Verify that your new pipeline also inherited the activities from pipeline template as expected. Go back to Service Bus Overview editor by finishing pipeline creation wizard and it should look like below.

Create Customer: Validation Stage. Finish Validate activity in both branches as shown previously in respective sections. BusinessService does not exist. Which was also created according to your instructions in another blog post. Any help appreciated! Here what is ServiceMetadataDerivedType? Hi, very nice Tutorial…but.. I got some problems…may be could you give us the source code Jdev Project in order to understand where i did a mistake.. You would see another proxy with these…this is also discussed in the tutorial at later stage..

We have proper error handling in place to handle all the error scenarios. Whenever we throw error manually using Raise Error action. Steps to Reproduce 1. Use Raise Error action in message flow with custom error code and handle it in service level handler. Use validate action for schema validation and raise error when validation fails.

Use service callout to call a SOAP web service. Instead we should receive JSON error with the structure defined in fault schema. I verified it and able to access it just using the below url.

The actual url is https: This tutorial has been a life saver — well presented, easy to follow and covering a wide variety of issues on the new 12c.
