What is the windows registry for JRE autodownload option in the Java Control Panel?

I want to set the JRE autodownload option found on the advanced tab of the Java Control Panel in Windows XP to 'Always Auto-Download' on a very large number of machines. What is the 开发者_如何学Gowindows registry key name for this option and the value for 'Always Auto-Download' ? Thanks!

Look for the C:\Documents and Settings\<USER_NAME>\Application Data\Sun\Java\Deployment\deployment.properties file.

Add line deployment.javaws.autodownload=NEVER after #deployment.properties if you want to set JRE Auto-Download to Newer.

Add line deployment.javaws.autodownload=PROMPT after #deployment.properties if you want set JRE Auto-Download to Prompt User.

Or delete deployment.javaws.autodownload option if you want set JRE Auto-Download to Always.
