This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
I am new to applets. I am not sure whether this question should be posted here. Is there anyway I can get the system information which is accessing a java web app through a browser. 1.Free hard disk space 2.CPU info 3.RAM 3.Operation System 4.Browser We can do it with ActiveX control, but is there anything equivalent in Java?
On your way in you may have missed that we have a policy on screen names here at JavaRanch. Basically, it must consist of a first name, a space, and a last name, and not be obviously fictitious. Since yours does not conform with it, please take a moment to change it, which you can do right here.
As to your question, some of this information can be gleaned from the HTTP User-Agent header (OS and browser), although that can be forged. CPU and OS is also available through Java system properties, but those are off-limits for regular applets - you'd need to digitally sign the applet to access these properties.

I would like to know what is the procedure to digitally sign the applet. And also how could we access the above mentioned properties like RAM and free hard disk space from an applet.
