RESTful Web Services in TIBCO

I am explain you how to create RESTFul Web Service using TIBCO BW REST & JSON Plugin.

Developing Process of Restful Web Service: 

1.Create Connection Shared Resources

2. Create XML Schema to be used as RESTFul Service Input and Output

3.  Create Business Logic Implementation process

4. Create RESTful Service Using REST Dispatch and Reply activity

5. Use Invoke REST API activity to consume RESTFul TIBCO Web Service

Create Connection Shared Resources:

RESTful TIBCO Web Service will use HTTP connection as a transport. So we need to create a HTTP Connection in our Project. Also, we need to create a JDBC Connection as we will be connecting to ORACLE database to fetch Account details from a table. JDBC Connection activity is available in the JDBC Palette. Please note that if you are using some other database system (like MS-SQL or DB2).

Create XML Schema to be used as RESTFul Service Input and Output:

To create a XML Schema (XSD file) that will be used for Request and Response in our TIBCO RESTFul Service Implementation. For our account query example scenario, Schema will contain only AccountID in the request while response will contain AccountBeneficiary and AccountBalance.

Create Business Logic Implementation process:

we are going to create a process which will have our service business logic implemented. Our business logic in this example case is very simple. We are just going to use the schema that we created in above step as Input and Output in our process and will use JDBC Query Activity to query account details from the database.

Create RESTful Service Using REST Dispatch and Reply activity:

We will create a service by using REST Dispatch and Reply activity from the REST & JSON Palette. Using REST Dispatch and Reply activity, we can expose a BW process as a RESTFul service. The BW process that we created in Step 3 will be used in this case as RESTful service implementation process.

Use Invoke REST API activity to consume RESTFul TIBCO Web Service:

To consume RESTFul Service, I have crated a new process and dragged Invoke REST API activity from REST & JSON Palette in it. In the configuration tab of Invoke REST API activity, specify the Resource URI. This URI should point to the resource that was added to our service in previous step (bas plus Resource URL).
