this should be no problem. a year ago i wrote a macro some time ago 
to work around  some weird encoding problems with the clipboard.
this macro inserts the output of xclip -o at the caret position. maybe
this helps you to get started.

void PasteX11Selection() {
 /** read a stream into a String with the platform default encoding */
 String readStream(InputStream in) {
  Reader   reader = new InputStreamReader(in);
  char[]   chunk = new char[1024];
  StringBuffer out  = new StringBuffer();
  for (;;) {
   int read = reader.read(chunk, 0, chunk.length);
   if (read < 0) break;
   out.append(chunk, 0, read);
  }
  reader.close();
  return out.toString();
 }
 
 // use xclip to access X11-selection content
 String[] xclip = { "xclip", "-o" }; 
 Process  proc = Runtime.getRuntime().exec(xclip);
 String stdout = readStream(proc.InputStream);
 String stderr = readStream(proc.ErrorStream);
 proc.waitFor();
 proc.exitValue(); 
 
 // insert text at caret position
 int caret = textArea.CaretPosition;
 buffer.insert(caret, stdout);
 textArea.CaretPosition = caret;
}

// check buffer vor changeability
if (buffer.isReadOnly()) { 
 Macros.error(view, "this file is read only."); 
 return; 
}
PasteX11Selection();
