QUESTION 1
Dave wants to see information about web service parameters, URL endpoint, and SOAP envelope. What must he do to obtain this data for a particular Web Service Call builder?

A.    There is no way for him to get this information other than contacting customer support.
B.    He must use a Java debugger to get this information.
C.    He must set the Logging field to All in the Web Service builder to log this information to the
WEB- INF/logs/debugTracing.txt file.
D.    This information is always printed to the standard output console log without any developer
intervention required.

Answer: C

QUESTION 2
Sean wants to trace the value of a variable as a model he is running to help track down a problem somewhere in a computation later in the model. How can he trace the value of the variable?

A.    Use the enable Debug Tracing field on the Variable builder.
B.    Add an entry to the log4j.properties file indicating the model and action to trace.
C.    Inspect the logging.properties file for variable values because all changes are reflected in this
file at run time.
D.    Add a Debug Tracing builder to the model specifying whether to trace all actions or naming a
specific action to trace.

Answer: D

QUESTION 3
Which of the following is the ideal development configuration for building and testing portlets?

A.    No publish is necessary. It all runs out of the project.
B.    Manually publish the portlet WAR file and let the designer discover its location.
C.    Publish the project two times, once to an application server, and once to an IBM WebSphere
Portal server for development and testing.
D.    Publish the application once to a WebSphere Portal server. IBM Web Experience Factory
development applications run stand-alone and as portlets with one configuration.

Answer: D

QUESTION 4
Tim has a web application that accesses a database through a provider model containing SQL Call builders. He thinks there might be a performance problem with one or more of the database calls. How can he get IBM Web Experience Factory to log detailed performance information about all aspects of the database access?

A.    He needs to use a SQL Override builder. This builder provides several fields that enable
detailed logging of performance information for database access.
B.    He must enable DEBUG-level database performance tracing in the Log4J properties file
and redeploy the WAR file.
C.    He must enable the Log Server Stats input in each SQL Call builder.
D.    No changes are required. Web Experience Factory automatically logs performance statistics
for all executed actions, such as database access calls.

Answer: C

QUESTION 5
Jane wants to debug the Java code in one or more of the Method builders in her model. How can she leverage the Eclipse Java debugger to do so?

A.    She must purchase full rights to the IBM Web Experience Factory source to debug
generated Java.
B.    This feature is not yet supported.
C.    Right-click a method in the Application Tree view to set/toggle a breakpoint. Start the
application server in debug mode and run the model with a remote Java debug configuration,
as documented in the Web Experience Factory help.
D.    System.out.println is the only way to debug Java associated with Method builders.
