3. Expand the com.ibm.dse.samples.appl package to find the

startupServerOpBean.java and startupServerOp.java file. Implement their

execute( ) methods:

For com.ibm.dse.samples.appl.startupServerOpBean.java, add

private String sessionID = null;

private Hashtable result = new Hashtable();

private Context aContext, parentContext, rootCtx;

See Figure 6-45 on page 179.

Chapter 6. Post-migration activities 179

Figure 6-45 Implement execute methods

Modify the execute() method. Change the following:

public Hashtable execute() throws BTTSAEException, Exception {

Hashtable result = new Hashtable();

//user code here

return result;

}

This should now look as follows:

public Hashtable execute(BTTSystemData sysData, String wksContext,String

wksParentContext) throws BTTSAEException, Exception {

Hashtable result = new Hashtable();

//user code here

try {

initialize(sysData);

setupSessionContext();

result.put("InstanceID", getInstanceId());

close();

} catch (BTTSAEException ex) {

ex.printStackTrace();

throw new DSEInvalidRequestException(DSEException.critical,

getClass().getName(),

"Not able to create the session context " +

" in " + getName() + " \n" + ex.toString());

}

return result;

}

180 IBM Branch Transformation Toolkit 5.1 Migration and Usage Guidelines

For startupServerOp.java, modify the execute() method. Change the

following:

public Hashtable execute()

throws BTTSAEException, Exception, java.rmi.RemoteException;

This should look as follows:

public Hashtable execute(BTTSystemData sysData,String wksContext,String

wksParentContext) throws BTTSAEException, Exception,

java.rmi.RemoteException;

See Figure 6-46

Figure 6-46 Execute method for startupServerOp.java

For the source code, refer to the Appendix (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).

4. In the same way, implement the execute( ) methods of the

endSessionServerOpBean.java and endSessionServerOp.java file:

For endSessionServerOpBean.java, modify the execute() method. Change

the following:

public Hashtable execute() throws BTTSAEException, Exception {

Hashtable result = new Hashtable();

//user code here

return result;

}

Chapter 6. Post-migration activities 181

This should look as follows:

public Hashtable execute(BTTSystemData sysData) throws

BTTSAEException,Exception {

initialize(sysData);

Hashtable result = new Hashtable();

Context sessionCtx ;

//if instanceID != null

if( getInstanceId() != null ){

// Removes the context and its parent (the parent session context)

sessionCtx = Context.getContextByInstanceID(getInstanceId());

if(sessionCtx instanceof Context)

sessionCtx.prune();

}

close();

return result;

}

For endSessionServerOp.java, modify the execute() method. Change the

following:

public Hashtable execute()

throws BTTSAEException, Exception, java.rmi.RemoteException;

This should look as follows:

public Hashtable execute(BTTSystemData sysData)

throws BTTSAEException, Exception, java.rmi.RemoteException;

For the source code, refer to the Appendix (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).

5. Save all the changes. If any error exists in the BaseSampleEJB project,

choose the Java Build Path in the Properties window of the project and add

the JARs bttbase.jar, bttfmt.jar, and bttsvrbean.jar to the Libraries tab and

select the bttsvcinfra and UserDefineJar projects in the Projects tab.

6. Make sure that all the errors in the BaseSampleEJB project have been fixed

before deploying. Right-click the project, and from the pop-up menu, select

Generate → Deployment and RMIC Code..., click Select All and Finish.
