prepareExercise

public static InteractionGenerator prepareExercise(String exerciseId,
                                                   User user,
                                                   String lang)
                                            throws IOException

Prepare for generating the interactions for the requested exercise. The default implementation loads the exercise description as XML. If the exercise identifier begins with "mbase:", it is fetched through MBase. If not, a file name is constructed by prepending the value of the property "exercises.location" as a path, and appending the suffix ".omdoc". The normal case is to use MBase, but the other possibility is there for debugging purposes, since the current MBase implementation in ActiveMath changes the content on storage, but the direct loading does not.

Parameters:

exerciseId - identifier for the exercise.

Returns:

interaction generator object for the exercise.

Throws:

IOException - can happen in case of direct loading.

prepareExercise

public static InteractionGenerator prepareExercise(String exerciseId,
                                                   String strategy,
                                                   User user,
                                                   String lang)
                                            throws IOException

Throws:

IOException

prepareExercise

public static InteractionGenerator prepareExercise(org.jdom.Document exercise,
                                                   User user)

Prepare for generating the interactions for the provided exercise. It is the same as prepareExercise(String exerciseId), but uses the provided exercise content instead of loading it.

Parameters:

exercise - exercise document.

Returns:

interaction generator object for the exercise.

loadExercise

protected static org.jdom.Document loadExercise(String exerciseId,
                                                User user)
                                         throws IOException

Throws:
