- - ### Field Detail

    - #### FILE_PROTOCOL_PREFIX

          static final java.lang.String FILE_PROTOCOL_PREFIX

      the file protocol prefix for systemid. This file protocol must be appended to an absolute path. Typically: `FILE_PROTOCOL_PREFIX + file.getAbsolutePath()` Note that on Windows, an extra '/' must be appended to the protocol prefix so that there is always 3 consecutive slashes.
