Your question doesn't make a lot of sense the way it is worded so I am going to go out on a limb and try to answer what I think you are saying. JWS and JNLP runs in a sandbox UNLESS you sign your code and request full permissions.

Java Code:

<?xml version="1.0" encoding="UTF-8"?>
<jnlp spec="1.0+"
  codebase="http://my.website.com"
  href="some/location/thisFile.jnlp">
<information>
  <title>App Title</title>
  <vendor>Your company</vendor>
  <homepage href="www.MyWebsite.com" />
  <description>Description of what this app does.</description>
</information>
<offline-allowed/>
<security>
  <all-permissions/>
</security>
<resources>	
	<jar href="some/location/someSignedJar.jar"/>
	<j2se version="1.6"/>	
</resources>
<application-desc/>
</jnlp>

This is an example, you need to read the JNLP spec to make sure you include the tags you need to run your app. In this example the file "/some/loction/someSignedJar.jar" on your website MUST be signed with a certificate in order for it to work.
