permission denied in jnlp trying call showDocument whit a pdf file
i need some help whit this showDocument in my jnlp aplication.
I trying show a pdf file in another tab from browser, but the java plugin denied.

My JNLP file has a 

      <security>
            <all-permissions/>
      </security>
and my code is:

        AccessController.doPrivileged(new PrivilegedAction()
		{
			@Override
			public Object run()
			{
				try
				{
					applet.getAppletContext().showDocument(new URL("file:///C:/Contrato.PDF"), "_blank");
				}
				catch(Exception e)
				{
					e.printStackTrace();
					showException("Erro ao exibir arquivo:" + e.getMessage());
				}
				return null;
			}
		});

but i receive that exception

        java.lang.SecurityException: showDocument url permission denied

if i try to do showDocument(google.com, _blank) that work..
but when i try to show any file.. do not.
