getInputStream in interface SchemeStrategy

Parameters:

sessionId - the Id of the current JVoiceXML session.

uri - the URI of the object to open.

method - type of the request method

timeout - fetch timeout in msec to wait for the content to be returned before throwing an error.badfetch event.

parameters - request parameters

Returns:

InputStream to the referenced object.

BadFetchError - error opening the document or unsupported method type

UnsupportedElementError - the requested element is not supported

IOException - error creating the input stream

getScheme

public String getScheme()

Get the scheme that is handled by this strategy.

Specified by:

getScheme in interface SchemeStrategy

Returns:
