Adding code to the BTTBankProcess project

Implement the DepositSnippetImplement class by performing the following tasks:

1. Open DepositSnippetImplement.java from the

btt.bank.business.logic.snippets package.

2. Add the import statements shown in Example 8-33.

Example 8-33 Additional import statements for DepositSnippetImplement.java

import com.ibm.btt.base.Context;

import com.ibm.btt.formatter.client.FormatElement;

import com.ibm.btt.services.jdbcjournalservice.Journal;

3. Add the code shown in Example 8-34 in the execute method.

Example 8-34 The execute method for the DepositSnippetImplement class

public int execute() throws BTTBPException {

System.out.println("Executed depositServerOp.snippets.initial");

//User code here

try{

// initialize context hierarchy

Context BPContext = getContext() ;

if(BPContext.getParent() == null){

Context parent= Context.getContextByInstanceID(getSystemData()

.getInstanceId());

BPContext.chainTo(parent);

}

// set data to deposit context

String hostBuff = ((FormatElement)getFormat("withdrawalCSRequestFmt"))

.format(BPContext);

setValueAt("HostBuff", hostBuff);

System.out.println("deposit BP context:\n" +

BPContext.getKeyedCollection());

// writes to the journal using the appropriate format

Journal journal = (Journal)getService("JournalService");

int recordNum = journal.addRecord(BPContext,"preSendJournalFmt");

// Set hard coded response data to deposit context

BPContext.setValueAt("TrxReplyCode", "00");

BPContext.setValueAt("AccountBalance", "10000");

BPContext.setValueAt("TrxErrorMessage", "depositOK");

// Update the electronic journal record

journal.updateRecord(recordNum,getContext(),"afterRecJournalFmt");

journal.releaseServiceRequester();

} catch(Exception e){

Running H/F 1 413

e.printStackTrace();

}

System.out.println("deposit : executeJournalHostRequestDataStep ok!");

return 1;

}

4. Save and close the Java Editor for DepositSnippetImplement.java.

5. Copy three files, DummyJournal.properties, RemoteEJB.properties, and

ServiceRequesterIDs.properties from the ejbModule folder of the

BTTBankEJB project to the BTTBankProcess project as shown in

Figure 8-150.

Generating deploy code for deposit.bpel

To generate the deply code, follow these steps:

1. Right-click the deposit.bpel file from the btt.bank.business.logic package of

the BTTBankProcess project. Select Enterprise Services → Generate

Deploy Code from the context menu, as shown in Figure 8-151 on page 414.

2. In the pop-up window, click ProcessPortType in the left navigation panel.

Select the SOAP/HTTP check box and then the Apache radio button. Click

OK, as shown in Figure 8-152.

Figure 8-152 Generate BPEL Deploy Code

Running H/F 1 415

The following projects are generated, containing the deploy code:

򐂰 BTTBankProcessEAR

򐂰 BTTBankProcessEJB

򐂰 BTTBankProcessWeb

You will see some errors. These can be fixed later (Can we say this? If the

solution is provided in this chapter/ book, shouldn’t we cross-reference it?).

Configuring generated projects

To configure BTTBankProcessEAR, perform the following tasks:

1. Ensure that both BTTBankProcess and DummyJournal projects are added

as the Project Utility JARs.

2. Import the following JARs from <BTT_install_dir>/jars to the

BTTBankProcessEAR project:

– bttbase.jar

– bttfmt.jar

– bttjdbjsvc.jar

– bttjdbtsvc.jar

– bttsvcinfra.jar

– bttsvcbean.jar

– bttsvrflow.jar

To configure BTTBankProcessEJB, perform the following tasks:

1. In the Java JAR Dependencies panel, ensure that both DummyJournal and

BTTBankProcess are added as the dependent JARs.

2. In the Libraries page of the Java Build Path panel, do the following:

a. Ensure that the JRE System Library is WebSphere v5.1 EE JRE.

b. Ensure that these two JARs are added into the build path. If not, add them

by clicking Add Variable.

• WAS_EE_V51/lib/wsadiebp.jar

• WAS_EE_V51/lib/wsatlib.jar

c. Add the following JARs into the build path (use those that are there in the

BTTBankProcessEAR project):

• bttbase.jar

• bttfmt.jar

• bttjdbjsvc.jar

• bttjdbtsvc.jar

• bttsvcinfra.jar

• bttsvrflow.jar

To configure BTTBankProcessWeb, in the Libraries page of the Java Build Path

panel, perform the following tasks:

a. Ensure that the JRE System Library is WebSphere v5.1 EE JRE.

b. Ensure that these two JARs are added into the build path. If not, add them

by clicking Add Variable.

• WAS_EE_V51/lib/wsadiebp.jar

• WAS_EE_V51/lib/wsatlib.jar

c. Add the following JARs into the build path (use those in the

BTTBankProcessEAR project):

• bttbase.jar

• bttfmt.jar

• bttjdbjsvc.jar

• bttjdbtsvc.jar

• bttsvcinfra.jar

• bttsvrflow.jar

To regenerate the deploy code for deposit.bpel, perform the following tasks:

1. Right-click the deposit.bpel file from the btt.bank.business.logic package of

the BTTBankProcess project. Select Enterprise Services → Generate

Deploy Code from the context menu, as shown in Figure 8-151 on page 414.

2. In the pop-up window, click ProcessPortType in the left navigation panel.

Select the SOAP/HTTP check box and then the Apache radio button. Click

OK.

Laying out the presentation logic for the deposit operation

Go back to the Graphical Editor. You will see that the canvas looks like the one

shown in Figure 8-153 on page 417. All the three components use the

withdrawalServerCtx. You can reuse the withdrawal.gph Web diagram and the

struts-btt-withdrawal.xml Struts module here.
