java - Call COM port from webpage -

-

i'm looking way call com port webpage.

i thinking abut running java webstart (or flash?) program opens local web server allows interact com port using jsonp.

are there show stopping security restrictions on way don't know of? should possible:

  • use native libraries (java com bridge) java ws application
  • open local port
  • access local port javascript, using <script> tags
  • do without scaring users "this website trying nasty, off fast can" kind of messages :)

i've used java com bridge before, shouldn't problem - @ least i'm able run native code.

so how jnlp file have working? alternatives java ws? better install daemon?

impossible. violates sorts of basic security principles, part do without scaring users "this website trying nasty, off fast can" kind of messages
