UUhistle as an Applet

This example code shows how to include UUhistle in a web page as an applet.

<applet id="UUhistle" 
        height="600" 
        width="550"
        name="UUhistle"
        archive="UUhistle_lean.jar"
        code="uuhistle.MainApplet.class">

  <param name="submit_type" value="POST">
  <param name="submit_url"  value="http://www.example.com/uuhistle_post.php">
  <param name="exercises"   value="http://www.example.com/exercises">

  Your browser doesn't support Java applets.

</applet>

You can use either UUhistle_lean.jar or UUhistle_full.jar from the Downloads page.

You can use the following applet parameters. All of them are optional.

Parameter	Explanation
course_id	An identifier for a course that uses the UUhistle applet. If this is given, then users of the applet can load example programs and exercises from a course config file whose name features the course ID. (See how to create course config files.)
exercise_id	An identifier of a particular example program within the course config file. If given, the exercise with this ID is immediately loaded when UUhistle starts. If there is a dot in the ID, the part before the dot is used as the course ID and the `course_id` parameter is ignored.
exercises	An URL that specifies the directory where the course config file is located. Unless given, the applet's location will be used as a default. Must begin with `http://` or `https://` (See how to create course config files.)
submit_type	If set to the value `POST`, allows users to submit their solutions (for grading and/or logging purposes). If not set, users can not send their solutions.
submit_url	Defines where results are POSTed. Required if `submit_type` is set to `POST`. Must contain the full URL, e.g. `http://www.example.com/uuhistle_post.php`. Read more on POSTing solutions.
user_id	A value that identifies the user (student) using UUhistle. If given, POSTed submissions will automatically contain this ID. Otherwise, UUhistle will prompt the user for an ID before they send a solution.
