This page describes a common interface between WeBWorK questions and Java, Flash and Geogebra applets.

Applets should respond when called by these functions

getXML() - the WW question is asking for an XML description of the applet's state. The description is text -- it is not base64 encoded. The XML description of the applet state should be suitable for use in setXML
setXML(state) - the applet is sending an XML description to reset the applet's state. The description is text -- it is not base64 encoded.
setConfig(configuration) - the applet is sending an initial configuration for the applet (should we use initialConfiguation or reset?) The description is text -- it is not base64 encoded.
getAnswer() -- the applet responds with a string simulating an answer entered by the student. This is typically called when the submit button is pressed.
isActive() - a 1 or "true" response by the applet indicates that the applet is loaded, initialized and ready to go.
debug() - set when the applet is called from WW. If debug=1 the WW question is in debug mode and if the applet has the ability to issue extra error messages these should be turned on. If debug=0 then these error messages should be turned off.

Demos of applets can be found at

The interface is still being tweaked and so expect minor changes to continue along with significant new features.
