why documentum webtop is shiped with java windows jre

I开发者_开发百科 found 2 big files in documentum webtop

 webtop\wdk\contentXfer\win-jre1.6.0_16.zip
 webtop\wdk\contentXfer\win-jre1.5.0_06.zip

Why webtop is shipped with it?

If all your users have java on their PCs then you can delete the JREs packaged with webtop. I have done this before. Also I stripped out other files not used. For example:

• the help files (not used as client did their own help)
• Delete Sources and Web Workflow manager
• Remove Themes

• Remove UCF Jars and JRE

  Make sure to check the runtime java version setting in: "wdk/contentXfer/ucf.installer.config.xml"

  Your PC clients must have at least this version of java installed. This is from Webtop 6.7

Webtop version 6.0 and above uses Java Applet for file operations such as check-in, check-out, import etc.

EMC named this technology as UCF. So to execute the Java Applet of this UCF technology Webtop shipped with Windows JRE.
