// For testing Component-managed authentication.

DummyLu0ConnectionSpec lu0ConnectionSpec = new DummyLu0ConnectionSpec();

lu0ConnectionSpec.setUserName("sna");

lu0ConnectionSpec.setPassword("sna");

Connection connection =

connectionFactory.getConnection(lu0ConnectionSpec);

System.out.println("connection created...");

// Beginning of testing SYNC_SEND_RECEIVE

Interaction interaction = connection.createInteraction();

System.out.println("interaction created...");

DummyLu0InteractionSpec interactionSpec = new

DummyLu0InteractionSpec();

DummyLu0Record in = new DummyLu0Record();

DummyLu0Record out = new DummyLu0Record();

in.setData((String) getValueAt("HostBuff"));

interactionSpec.setInteractionVerb(InteractionSpec.SYNC_SEND_RECEIVE);

interactionSpec.setExecutionTimeout(10000);

interaction.execute(interactionSpec, in, out);

System.out.println("data from host: " + out.getData());

interaction.close();

System.out.println("interaction closed...");

connection.close();

System.out.println("connection closed...");

com.ibm.btt.formatter.client.FormatElement fromHost =

(com.ibm.btt.formatter.client.FormatElement) getFormat("withdrawalRecFmt");

//$NON-NLS-1$

fromHost.unformat(out.getData(),getContext());

}catch(Exception e){

e.printStackTrace();

}

Change "return 0" to" return 1".

For withdrawalServerOp.snippets.state3, add the import class code in

Example 6-17 on page 168 on top:

Example 6-17 Import class code for withdrawalServerOp.snippets.state3

Chapter 6. Post-migration activities 169

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

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

In execute() method add the code in Example 6-18.

Example 6-18 Execute() method code for withdrawalServerOp.snippets.state3

try{

Journal journal;

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

journal.addRecord(getContext(), " afterRecJournalFmt ");//$NON-NLS-1$

journal.releaseServiceRequester();

}catch(Exception e){

e.printStackTrace();

}

Change "return 0" to "return 1";

For the source code, refer to Appendix A, “Branch Transformation Toolkit

development and runtime requirements” on page 477 and Appendix B,

“Setting up a Branch Transformation Toolkit sample application” on page 493.

12.Modify the BPEL file for the withdrawalServerOp business process.

Find the package named withdrawalServerOp, and double-click

withdrawalServerOp.bpel to edit.

a. Select withdrawalServerOp. It’s properties are displayed in the lower

panel. Select Environment, and change the ContextMode to remote, also

add "TrxReplyCode, AccountBalance, TrxErrorMessage" to the MapList.

See Figure 6-39 on page 170.

In the editor, select initial → Implementation. Delete the second line of

the code.

b. In the same way, select state2 → Implementation. Delete the second

line of the code.

c. Save and close the BPEL file.

Figure 6-39 Modify environment properties for withdrawalServerOp.bpel

13.Modify the wsdl file for the withdrawalServerOp business process.

In the same package, open withdrawalServerOpInterface.wsdl with Source

Editor. Add two new lines in the message tag named InputMessage:

<part name="Amount" type="xsd:string" />

<part name="AccountNumber" type="xsd:string" />

Save and close withdrawalServerOpInterface.wsdl.

14.Implement the snippets for the accountStatementServerOp business

process.

Expand the BaseSampleProcess project, and find the package named

accountStatementServerOp.snippets. Edit three Java files inside, initial.java,

state2.java, and state3.java.

Chapter 6. Post-migration activities 171

For accountStatementServerOp.snippets.initial, add the need to import class

code on top:

import com.ibm.btt.base.Context;

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

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

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

In execute() method add code:

try{

if(getContext().getParent()==null)

//getContext().chainTo(Context.getContextNamed("javaSessionCtx"));

getContext().chainTo(Context.getContextByInstanceID(getSystemData().getInst

anceId()));

Journal journal;

setValueAt("HostBuff",((FormatElement)getFormat("accountStatementSendFmt"))

.format(getContext()));//$NON-NLS-2$//$NON-NLS-1$

// writes to the journal using the appropriate format

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

journal.addRecord(getContext(),"preSendJournalFmt ");//$NON-NLS-1$

journal.releaseServiceRequester();

} catch(Exception e){

e.printStackTrace();

}

Change "return 0" to" return 1".

For accountStatementServerOp.snippets.state2, add the need to import class

code on top:

import java.util.Hashtable;

import javax.resource.cci.*;

import com.ibm.btt.base.*;

import com.ibm.btt.samples.business.sna.lu0.DummyLu0ConnectionSpec;

import com.ibm.btt.samples.business.sna.lu0.DummyLu0InteractionSpec;

import com.ibm.btt.samples.business.sna.lu0.DummyLu0Record;

import com.ibm.btt.services.*;

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

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

In execute() method add code:

try{

javax.naming.Context initialContext = null;

ConnectionFactory connectionFactory = null;

if (initialContext == null) {

initialContext = new javax.naming.InitialContext();

connectionFactory = (ConnectionFactory)

initialContext.lookup("snalu0");

DummyLu0ConnectionSpec lu0ConnectionSpec = new

Connection connection =

System.out.println("connection created...");

interactionSpec.setExecutionTimeout(10000);

interaction.execute(interactionSpec, in, out);

System.out.println("data from host: " + out.getData());

interaction.close();

System.out.println("interaction closed...");

connection.close();

System.out.println("connection closed...");

com.ibm.btt.formatter.client.FormatElement fromHost =

(com.ibm.btt.formatter.client.FormatElement)

getFormat("accountStatementRecFmt"); //$NON-NLS-1$

fromHost.unformat(out.getData(),getContext());

}catch(Exception e){

e.printStackTrace();

}

Change "return 0" to" return 1".
