open y our ec lipse and go on!!.

Definitions

Oracle Serv ice Bus Configuration Projec t - A fter opening the

eclipse create the osb c onfiguration project which hold

multiple osb projec ts.

OSB project - holds the actual application which c onsists of

proxy services and business services.

Proxy Service - which holds the actual flow

implementation. It c an perform routing,

transformation,sercurity , monitoring and reporting

Business Serv ice , which acts as an abstract acce ss layer for

the end system component where we co nfigure the

interface. Prox y ser v ice calls the end system using business

serv ice. Business serv ices can be of HTTP, JMS, MQ, File ,

Open the new prox y serv ice and c lick on the 'Transport' section.

Select the proto col as 'http' and give a proper HTTP access URI.

Click on the 'Message Flow' section o n the prox y serv ice and drag a

'pipeline pair' to the message flow.

Y ou can see 'Request pipeline ' and 'Respo nse pipeline' inside the

pipeline pair.

Drag a 'stage' into the Request pipeline. Stage is used just to gro up

different nodes in the flow.

Now Right click on the Oracle Service Bus Project and create a new

'business serv ice'

Open the new business serv ice and c lick on 'Transport' section .

Configure 'http' as protoc ol and add o ne prope r end sy stem URI.

In the figure given belo w, it is co nfigured as

http://www.google.com. Instead please configure any tomc at

stub which gives any x ml as the output.

Go bac k to the pro xy serv ice. Drag 'Service call out' to the 'stage'.

The service c all out is used to initiate a request to the end sy stem

with the help o f business serv ice and get back the response.

5/11



Click on the serv ice c all out and then c lick on the 'Browse' button

below and select the business serv ice.

Enter the Request v ariable as 'body ' and response v ariable as

'response'. Yo u can use any name for the response variable. But

for the request variable you should use 'body ' as the request xml

resides in the 'body ' v ariable.

Drag a 'replace' node to the response pipeline pair and co nfigure it.

This will co py the response o btained from the downstream to the

bo dy variable so that the r espo nse will be returned to the client.

Finish creating the serve r and right click on the serv er cre ated and

select 'Add and Remove' and add your Oracle Service Bus

Configuration Project to the serv er.

Right click on the 'Serv er' and click on 'start'. After some time the

serv er will go to the 'Running' state.

Right click on the serv er and c lick on 'publish' so that y our

application will be deploy ed .

Testing the application Right click on the proxy serv ice and select 'Run As' and select

'Run on Serv er' . A new window will be opened and paste some x ml

and hit run. If there are no errors in the end sy stem stub, yo u willget proper output.

Note : Make sure that your managed serv er is running before

testing the application.

Paste one x ml on the 'Paylo ad' section and hit 'Execute'

If your stub is working properly, Y ou can see the proper response.

Conclusion This topic is just intended to kick start the dev elopment. There

are more things ahead. Any way y ou have taken the first step of

OSB application development. Try to ex plore more in it.
