Download the client from: http://properjavardp.sourceforge.net/ and then upload it under Resource Profiles as a new Web, Hosted Java Applet. Then add it to the appropriate roles and create whatever custom bookmarks you need, modifying the HTML code to match your preferences. 

Here is the HTML code that is generated by default:

archive="properJavaRDP12-1.1.jar,properJavaRDP13-1.1.jar,properJavaRDP14- 1.1.jar,properJavaRDP-1.1.jar,java-getopt-1.0.11.jar,log4j-java1.1.jar,properJavaRDP11-1.1.jar" width="640" height="480" name="ProperJavaRDP" align="top">

Here is what it looks like on a production system (what you would likely replace the generated code above with...after modifying to your liking): Running just the desktop:

Running Notepad:

TIPS: • You can add as many bookmarks as you need, with each one having completely different settings (just using the html code to define the differences) while still using the same uploaded Java files. • You might create one bookmark that says "RDP Desktop 800x600" and another that says "RDP Desktop 1024x768", to allow the end user to decide which resolution they prefer. • Use the description field to inform the user of what you want them to know before they access the link, such as make sure you are running Sun Java if the link does not load appropriately; and use this link to access the servers from a kiosk or Linux or Mac PCs. • For advanced security, tighen up the Java Access Control to be something more specific than just *.
