Clients can be launched in a web browser with Java in Applet mode from the Gateway Webpage or the Designer.
The google chrome web browser platform will no longer support Java applets starting in 2015. However, Java applets will still be available on other web browsers. Also, your browser may block a Java Applet from launching, therefore you may need to unblock access to Java Applets.
To launch a Client in Applet mode
Go to the Gateway Home page.
Select the Applet mode from the drop down option associated with the launch button associated with your project.
The project should launch in its own window on your web browser.
