BANKING
DATE:
AIM:
To implement banking using .NET component.
ALGORITHM:
Creating the Component
Start Visual Studio .NET and open a new Class Library project – File -> New project. In the
New Project dialog box, name the project as ClassLibrary1.
Change the name of the class from Class1 to Component name.
Enter the Component code into the new class module. Include the following
functions:Getpass(), balenquiry(), withdraw(), deposit().
Compile this class as a DLL by clicking Build on the Debug menu.The DLL that results
from the build command is placed into the bin directory immediately.
To add a Database connection, click on Data -> Add data source and add a new connection.
Browse and select the database created in the MS Access.
Select the table and test the connection. If successful copy the connection string.
Creating the Application
Start Visual Studio; clickFile -> New project -> Visual C# -> Windows form application.
Set the Name property of the default Windows Form
Design the Form by placing controls and naming them.
You need to set a reference to the DLL so that this form will be able to consume the
components services.
Do this by following the steps below.
From the class menu click Add Reference.
Select the necessary DLL component from the browse menu.
Run the application

EX No: 7(b) DEVELOP A SERVICE ORCHESTRATION ENGINE(WORK FLOW)
USING WS-BPEL AND IMPLEMENT SERVICE COMPOSITION FOR
TRAVELS(AIRLINE)
DATE:
AIM:
Develop a Service Orchestration engine(work flow) using WS-BPEL and implement
service composition. To createa business process for planning business travels that will invoke
several services. This process will invoke several airline companies to check the airfare price and
buy at the lowest price.
PROCEDURE:
1) Create a sample web application :
File->new project-> in the catogories choose java web and in the projects tab select web
application->click next-> give a name for that new web application in the project name
(TestService1)-> accept the defaults and click finish.. In the projects tab our TestService1 has
been created.
168. 44210205028
2)Creation of Web Service:
Our web service reduces the amount by 5% and returns the value:
Right click our TestService1from that select new webservice. Give appropriate name to that web
service.
Web service name:TestWebservice
Package name: com.service
Make sure that create web service from scratch is selected.
Click finish.
3) Viewing for Our Web Service
Our new TestService.java web service opens up
Select the design tab->Click add operation
169. 44210205028
4) Creation of Operation for Our Web Service
Our web service takes in amount reduces 5% tax in that and returns the amount.
Input parameters:java.lang.Long
Output parameters:java.lang.Long
Operation name:TaxReduction
Click the add operation->a new add operation box pops up->in tha
name field:TaxService(operation name)
return type: click the browse button->type long-> select java.lang.Long from the option
parameters tab:InputAmount(NameFeild),long(Typefeild)
click ok
our TaxReduction operation shows up.->click the source view to write code
170. 44210205028
4) Paste the Code in our Operation
double amt=InputAmount-(InputAmount*0.05);
Long res=(new Double(amt)).longValue();
return res;
5) Click on the project tab there we can see our TestService web service in the web service
folder.
First right click the project and run the web application we created.
RightClick->TestWebservice to test our web service
172. 44210205028
7) We get the output as 142500
Similarly create another web service CheckRange web service this checks the input amount and
responds the type of travel based on the amount.
Here is the code for that service.
String res;
if(parameter<=5000){
res="eligible for bus travell";
}else if(parameter>5000&¶meter<=10000){
res="eligible for train travell";
}else{
res="eligible for flight travell";
}
return res;
173. 44210205028
7) BPEL CREATION
File->new->new project->select soa in catogories andBPEL module in project
Give a name for BPEL and accept the defaults.
Now a project is created and we have to create a BPEL right click on the project we created new>BPEL Process
Now give a name to our BPEL process and click finish. A sample BPEL file is created.
174. 44210205028
8) Now we need to create a client side interface to our BPEL process this is done by creating
WSDL file specifying the input to BPEL process and output from BPEL process
Right click project->new->new WSDL
Specify the name of the WSDL in the file name->click next
specify the inpu and output parameters in the WSDL ->cick next
for our scenario long is the input and string is the output from our BPEL process
->click next-> finish
Now a new WSDL client has been created for Sample BPEL process.
Drag the WSDL created in our BPEL Design window
9) Now drag the receive from the palette box into the BPEL diagram
176. 44210205028
11) Double click the receive and a new window opens click the create near the input variable a
new variable input variable opens accept the defaults and click ok.
12) Now drag the reply and connect a wire from reply to clientWSDL as same as receive
13) When you double click the reply you will get a window click the create button make sure
normal response is selected. Create new output variable opens. Click ok.
177. 44210205028
14) Now we have to create a partner link for web service invocation in our project.
Go to the project tab and go to the web service we created. Right click the TestService
webservice and select generate and copy WSDL. Select our BPEL project src folder and click
ok.WSDL is copied into our BPEL project drag the WSDL into our BPEL editor.
15) We need to invoke our web service method into our BPEL process. So we need to drag a
invoke method into BPEL between receive and reply now double click the invoke a new window
opens. Select the partner link just created(partnerlink 1) it drops down the operation in that select
the operation. click create for creating input variable.similarly for output variable.click ok
178. 44210205028
Similarly do the same for the next web Check rangeweb service we created.thus our BPEL
should contain two service invocation.
179. 44210205028
Our BPEL process should first get the long amount from client and pass it to TaxReduction web
service fro tax reduction and that output should be sent to checkrange service for checking range.
The output from that checkrange service will be the output from out entire BPEL process
16) Now we have to assign the client input to TaxReductionservice.first drag a assign from
palette and place it between receive and first invoke(TaxReduction). Double click assign . then
mapper tab opens up. We have to assign the clientWSDLoperationinput to taxreductioninput.
Click the clientWSDLoperationinput shows a part field.similarly click the Taxreduction
operation in parameters field opensclick that once again inputamount opens.Just drag a wire
frompart to inputamount.now we have assigned the BPEL input to taxreduction input.
17) Click on the design tab.now from taxreduction service to checkrange service.once again drap
the assign and place between the taxreductioninvoke and checkrangeinvoke.
181. 44210205028
Overall BPEL process design will look like this.
Now we have to specify the sopa address for the WSDLwe have imported. Select the imported
WSDL files in BPEL you can see services in the navigator window
