Downloading and installing JNLP and JAR files can be a problem for users, for example due to security restrictions. Also, not all JDKs contain JNLP.
An alternative is to download the JAR file and to deploy it to client machines through the command line or a batch file. You can download the JAR file from: http://<server>:19120[/instance_name]/ManualTesting/capture/manualtestingapplet.jar
To launch the application from the command line, use the following command:
java -cp manualtestingapplet.jar com.borland.sctm.manualtesting.ManualTestingApplet 19150 "Manual Testing | Silk Central" "Keep this application running in the background to enable screen and video capturing." "en"
This way, the manual testing application can be automatically started or testers can start it on demand using a desktop shortcut.
