c. From the list of inherited members, right-click the execute method of

DSEClientOperation and select Override in

‘WithdrawalClientOperation’, as shown in Figure 8-176.

Figure 8-176 Override execute method in WithdrawalClientOperation

11.Write the WithdrawalClientOperation.execute() method, by performing the

following tasks:

a. Get the service named CSClient. This gets the client instance of

client/server service from the operation's context hierarchy.

b. Cast this service to CSClientService.

c. Use the service to invoke the synchronous sendAndWait(ClientOperation,

long) method. The first parameter is the client operation, "this". The

second parameter is a time-out in milliseconds. An appropriate value can

be 60000, or 60 seconds.

}

12.Save and close WithdrawalClientOperation.java.

13.Create a new class named StartupClientOp extending

com.ibm.dse.base.DSEClientOperation in the package btt.bank.client.appl.

As described in Step 8, override the execute method of DSEClientOperation

in StartupClientop. Import the com.ibm.dse.base.* package and the

com.ibm.dse.clientserver.* package. Implement the execute method of

StartupClientOp as shown in Example 8-38.
