Specify security access in JNLP

[Gerrit Hulleman]

Is it possible to specify what access the web start application needs to
run?

Using the JNLP code
<security>
<all-permissions/>
</security>

All access can be gained, but I would like to restrict it to contacting
certain servers and clipbaord access. More like 'java.awt.AWTPermission
"accessClipboard"'. Is it possible to use this policy code in the JNLP file?
