Preparing Java Web Start Applications for Testing With TestComplete

Applies to TestComplete 15.65, last modified on July 17, 2024

Support for Java Web Start has been removed from Java version 11.

TestComplete provides access to Java Web Start applications (.jnlp) that are open in Internet Explorer.

Before testing your Java Web Start application, you may need to configure the environment in order for your tests to work correctly.

Preparing the Javaws.Policy File

To configure the javaws.policy file, do the following:

  • Locate the javaws.policy file, which is normally located in the <Java-dir>\lib\security\ subfolder of the JRE (Java Runtime Environment) folder.

    You need to prepare the javaws.policy file for the JRE that has the same bitness as the tested Java Web Start application.
  • Open this file in the appropriate text editor.

  • Write the following lines for the grant group:

    permission java.lang.RuntimePermission "";
    permission java.lang.RuntimePermission "accessDeclaredMembers";
    permission java.lang.reflect.ReflectPermission "suppressAccessChecks";

If You Use JavaFX

If your Java Web Start application contains JavaFX controls, then you need to make any of the following changes to the <Java-dir>\lib\security\javaws.policy file:

  • Add the permission (it will enable all the other permissions):

    grant {

– or –

  • Specify the permission for the codebase of your Java Web Start app:

    grant codeBase "file:///c:/work/my-javafx-app.jar" {

Preparing the Web Browser

If you are testing a Java Web Start application embedded into a web page, you may need to configure your browser. For example, you may need to set the page’s zoom ratio or prevent security warnings. For detailed instructions, see Preparing Web Browsers.
