Preparation: Create a Project

Choose project type Java / Java RMI/EJB (recording)

3

5 13.02.2008

Preparation: Profile Settings

Select a Java JDK (version 1.2 or higher)For use internally by the recorderUsed for replay via SilkPerformer Java Framework

Add the Classpath elements that are required by therecorded application

The classpath is not required for recording. It is required for:Compiling the recorded scriptReplay

Preparation: Profile Settings

Java options

Choose a JDK Define the classpath

Preparation: Profile Settings

Set the record log level to DebugWhen contacting technical support, send exported projects with Debug logging enabled

Set log level to Debug

8 13.02.2008

Preparation: Application Profile

Define an application profile for the application you wantto record

Add a new application profile

Enter the path to the executable / startup script (.exe, .bat, or .cmd)

Enter the name of the executablethat hosts the Java VM

(e.g., java.exe or javaw.exe)

Select Custom Application

Select the Java APIs that are to berecorded

Recording IBM‘s Java virtual machine requires additional settings

Preparation: Application Profile for IBM JVM

Edit Java Settings Select Manual

10 13.02.2008

Preparation: Startup Script for IBM JVM

Recording IBM‘s Java virtual machine also requires a customized startup script

Original startup script

Insert call to perfPrepareJavaRecording.cmd

(adjust SilkPerformer‘s home directory if necessary)

Add the command line parameter %PERFREC_OPTIONS%

Customized copy of startup script

Recorded Result

x.javaThe Java source file that contains the recorded actionsThis file can be compiled from within the SilkPerformer Workbench

The file is compiled automaticallyThe classpath must be specified correctly (Java Profile Settings)

x.bdfBDL stub code that launches the Java virtual user

Testing Applets

Recording AppletsUse Sun Java VM in the browser (not Microsoft)

ReplayRemove the recorded API calls:JavaSetOption(JAVA_CLASSPATH and JavaSetOption(JAVA_CMDLINE_OPTIONS from the BDL scriptObtain JAR and CLASS files from the server; copy these files to the local machine; enter the classpath in Java Profile Settings.

Use recorded comments in the recorded Java source code to find JAR and class files

Example: Product Manager

The RMI sample application that ships with SilkPerformer is called Product Manager.To launch Product Manager, go to: C:\Borland\SilkPerformer/Sample Applications/Java Samples/Product Manager

16 13.02.2008

Example: Create a Project

Project type: Java / Java RMI/EJB (recording)

17 13.02.2008

Example: Application Profile

Modify the existing Internet Explorer application profile

Deselect WebSelect Java RMISelect Java JNDI

This is required because this sample uses JNDI for the bootstrapping of remote object references

18 13.02.2008

Example: Profile Settings

Specify script generation details at Profile Settings / Record / Script / Java

19 13.02.2008

Example: Profile Settings

Specify Java SettingsAdd ProductManager.jar from the SilkPerformer samples directory

20 13.02.2008

Example: Start Servers

Start the RMI and LDAP servers

Open the Product Manager sample HTML page and follow the instructions:

Step 1: Start the LDAP databaseStep 2: Start JNDI name serverStep 3: Start RMI over IIOP server

11

21 13.02.2008

Example: Model Script

Open the Model Script dialogEnter the location of the RMI sample application HTML pageClick the ProductManager – DemoVersion.htm link to launch the applet

The applet loads and the recorder begins recording the JNDI and RMI activities of the applet.Perform searches for products; change products; add new products, etc.

Example: Save the Recorded Script

Save the recorded script

Specify a valid Java identifier
