If your J2EE app is deployed on the same server the PHP script is on, you can also execute it directly through as an independent process like this:

  public String execPHP(String scriptName, String param) {
    try {
      String line;
      StringBuilder output = new StringBuilder();
      Process p = Runtime.getRuntime().exec("php " + scriptName + " " + param);
      BufferedReader input =
        new BufferedReader
          (new InputStreamReader(p.getInputStream()));
      while ((line = input.readLine()) != null) {
          output.append(line);
      }
      input.close();
    }
    catch (Exception err) {
      err.printStackTrace();
    }
    return output.toString();
  }

You will pay the overhead of creating and executing a process, but you won't be creating a network connection every time you need to execute the script. I think that depending on the size of your output, one will perform better than the other.
