QTP support tip: Load Java support without using the _JAVA_OPTIONS environment variable?

The _JAVA_OPTIONS environment variable is automatically created during Java and Oracle Add-in's installation. This environment variable will load Java support automatically when starting the Java application.

There may be instances where a user may not be able to use this additional environment variable. How would a user load Java support without using the _JAVA_OPTIONS environment variable?


Launch the Java application using options "-Xrunmicsupp" and "-Xbootclasspath" options to the application's command line to load Java support, without use of environment variables.

To configure a Java application with java.exe, the following command line should be used:

java -Xrunmicsupp -Xbootclasspath/a:<mic_classes> <ApplicationClass>

By default, <mic_classes> is "<UFT/QTP>\bin\java_shared\classes;<UFT/QTP>\bin\JAVA_S~1\classes\jasmine.jar"

  • QuickTest Professional: "C:\Program Files\HP\QuickTest Professional\bin\java_shared\classes;C:\PROGRA~1\HP\QUICKT~1\bin\JAVA_S~1\classes\jasmine.jar"
  • Unified Functional Testing: :"C:\Program Files (x86)\HP\Unified Functional Testing\bin\java_shared\classes";"C:\Program Files (x86)\HP\Unified Functional Testing\bin\java_shared\classes\jasmine.jar"


java -Xrunmicsupp -Xbootclasspath/a:C:\PROGRA~1\HP\QUICKT~1\bin\JAVA_S~1\classes;C:\PROGRA~1\HP\QUICKT~1\bin\JAVA_S~1\classes\jasmine.jar –jar C:\SwingSet2\SwingSet2\SwingSet2.jar




Note: It is possible to create a batch file containing command lines and launch your application via the batch file.
