Hai,
Below code would solve your problem of reading the mpp file using mpxj API . Below code is an example of standalone application which takes and argument of mpp file name with out extension. ex. temp.mpp file is given as "temp" argument to the application. Compile and run the file.
//import com.tapsterrock.mpp.MPPFile;
import java.util.*;
import com.tapsterrock.mpx.MPXFile;
import com.tapsterrock.mpx.Task;
import com.tapsterrock.mpx.*;
public class MPPReadTest extends Thread
     public static void main(String[] args)
          try{
int i=0;
Runtime rt=Runtime.getRuntime();
Process p=rt.exec("java com.tapsterrock.utility.MppMpx "+args[0]+".mpp "+args[0]+".mpx");
p.waitFor();
MPXFile mpx=new MPXFile(""+args[0]+".mpx");
LinkedList llist=mpx.getChildTasks();
for(i=0;i<llist.size();i++)
Task t=(Task)llist.get(0);
System.out.println("Task Details : \n"+llist.get(0));
System.out.println("\n\nTask name : "+t.getName());
System.out.println("Task Unique ID : "+t.getUniqueID());
System.out.println("Task Unique ID : "+t.getUniqueID());
System.out.println("\tStart Date : "+t.getStart());
System.out.println("\tFinish Date : "+t.getFinish());
System.out.println("\tDuration : "+t.getDuration().getDuration());
getSubTasks(t,t.getUniqueID());
          }catch(Exception e)
               System.out.println("Error : "+e.toString());
public static void getSubTasks(Task tt,Integer parentTaskId)
int i=0;
int j=0;
Integer tempTaskId=new Integer(0);
if(tt.getChildTasks().size()>0)
for(i=0;i<tt.getChildTasks().size();i++)
Task t=(Task)tt.getChildTasks().get(i);
if(parentTaskId==t.getParentTask().getUniqueID())
System.out.println("\n\nTask name : "+t.getName());
System.out.println("Task Parent Unique ID : "+t.getParentTask().getUniqueID());
System.out.println("Task Unique ID : "+t.getUniqueID());
System.out.println("\tStart Date : "+t.getStart());
System.out.println("\tFinish Date : "+t.getFinish());
System.out.println("\tDuration : "+t.getDuration().getDuration());
tempTaskId=t.getParentTask().getUniqueID();
else
tempTaskId=t.getUniqueID();
System.out.println("\n\nTask name : "+t.getName());
System.out.println("Task Parent Unique ID : "+t.getParentTask().getUniqueID());
System.out.println("Task Unique ID : "+t.getUniqueID());
System.out.println("\tStart Date : "+t.getStart());
System.out.println("\tFinish Date : "+t.getFinish());
System.out.println("\tDuration : "+t.getDuration().getDuration());
LinkedList resources=t.getResourceAssignments();
if(resources.size()>0)
for(j=0;j<resources.size();j++)
System.out.println("\n\t Task ID \t\t Task Name \t\t\t\t\t ResourceID \t\t Resource Name");
System.out.println("\t"+t.getUniqueID()+"\t\t\t\t"+t.getName()+"\t\t"+((ResourceAssignment)resources.get(j)).getResource().getUniqueID()+"\t\t\t\t"+((ResourceAssignment)resources.get(j)).getResource().getName());
if(t.getChildTasks().size()>0)
getSubTasks(t,tempTaskId);
else
