public boolean processArguments(TreeLogger logger,
                                String arguments)

Process any supplied arguments.

Will be called before start(TreeLogger, int, File), if at all.

Parameters:

logger - logger to use for warnings/errors

arguments - single string containing the arguments for this SCL, the format to be defined by the SCL

Returns:

true if the arguments were processed successfully

setBindAddress

public void setBindAddress(String bindAddress)

Will be called before start(TreeLogger, int, File), if at all. If not called, the SCL should listen on all addresses.

Parameters:

bindAddress - host name or IP address, suitable for use with InetAddress.getByName(String)

public abstract ServletContainer start(TreeLogger logger,
                                       int port,
