How To: Write MPX files

Versions of Microsoft Project up to Project 98 could read and write MPX files as a data interchange format. Versions of Project after Project 98 until Project 2010 can only read MPX files. Versions of Microsoft Project after 2010 cannot read MPX files. Other third party project planning applications continue to use MPX as a data interchange format.

The sample code below illustrates how to write data to an MPX file.

import net.sf.mpxj.ProjectFile;
import net.sf.mpxj.mpx.MPXWriter;

// ...

MPXWriter writer = new MPXWriter();
writer.write(projectFile, outputFileName);
