The MPXJ library provides a set of facilities to allow project information to be manipulated in Java. MPXJ supports three file formats, Microsoft Project Exchange (MPX), Microsoft Project (MPP), and Microsoft Project Data Interchange (MSPDI).
The library is currently based around a set of data structures modelled on the data described by the MPX file format. All manipulation of project data takes place using these data structures, which can be read from or written to the various supported file formats. The following notes explain what facilities MPXJ offers for each file format.
MPX: The MPX file format can be read by all versions of Microsoft Project, and written by all versions up to Microsoft Project 98. MPXJ allows MPX files to be created, read and written. See http://support.microsoft.com/default.aspx?scid=KB;EN-US;Q270139 for a definition of the file format.
MPP: The MPP file format is Microsoft's proprietary way of storing project data. MPXJ supports read only access to MPP files produced by Microsoft Project 98, Microsoft Project 2000, Microsoft Project 2002, and Microsoft Project 2003.
MSPDI: The MSPDI file format is Microsoft's XML file format for storing project data. Microsoft Project 2002 and Microsoft Project 2003 can read and write MSPDI files. MPXJ allows MSPDI files to be created, read, and written.
is an open source Java implementation of a file handling library to create, read, and write Microsoft Project Exchange (MPX) files, Project 2002 and 2003 MSPDI XML files, and read Microsoft Project 98, 2000, 2002, and 2003 (MPP) files.
