Java application testing problems

When working with Java applications, you can encounter some problems. This section helps pinpoint and resolve some common problems that may occur when testing Java applets and applications.

Running another application/applet with the same settings

You can run another Java application or applet with the same settings as the one you are currently running to help determine whether you are encountering a general problem with the Java Add-in or an application-specific problem.

When running another Java application or applet, do the following:

  • Determine whether the application is a standalone application or an applet.

  • If the application is an applet, check the browser type.

  • If the applet is executed from a shortcut, execute another applet with the same command.

  • If the applet is executed from a batch file, copy the batch file and change only the class file that invokes the applet.

    If the classpath must also be changed, add only the new items needed. Do not remove any of the items from the original application or applet classpath.

Check that the settings in your environment correspond to the environment settings defined in this section, or check for a batch file that may override the settings.

A different application works but current application does not

First check whether you can record and run tests if you invoke the other Java applet or application using exactly the same settings.

Check that the settings in your environment correspond to the environment settings defined in this section, or check for a batch file that may override the settings.

UFT One 2021 R1 or earlier: Java 6

The following known issues are related to using Java 6:

If you are using Oracle Java JRE 5 or 6 on Microsoft Internet Explore, the JVM might not use the Java settings added to your system's environment variables.

Check that the settings in your environment correspond to the environment settings defined in Java environment variables, or check for a batch file that may override the settings.

In addition, you may need to do the following:

  1. Add -agentlib:jvmhook at the beginning of the _JAVA_OPTIONS and IBM_JAVA_OPTIONS environment variables.

  2. Delete the JAVA_TOOL_OPTIONS environment variable.
