What is OpenProj?
OpenProj is an open-source desktop project management application similar to Microsoft Project. OpenProj has a familiar user interface and even opens existing MS Project files. OpenProj is interoperable with Project, Gantt Charts and PERT charts.

System requirements
  • Minimum JRE version is 1.6
  • Minimum 512Mb RAM internal memory. You might need more if you expand the data.

OpenProj on an eComStation machine with Open JDK


Installing OpenProj
Download the file openproj-1.4.zip. Create a folder (directory) "Openproj". Open the zip file with a filemanager. Now you get a folder (directory) with the name "openproj-1.4". Open the folder "openproj-1.4" and copy the contents to the new folder "Openproj". Remove the files "openproj.sh" and "openproj.bat", we can't use these files. The file "openproj.bat" is a batch file and can run in OS/2-eComStation, but there is no reference to Java.

The used cmd file
OpenProj works well with Open JDK in OS/2-eCS. I have a openproj.cmd file with the following contents; 
@echo off
SET CLASSPATH=
set BEGINLIBPATH=[drive: java]\JAVA160\bin
set path=[drive: java]\JAVA160\bin
[drive: Openproj]
cd [drive: Openproj]\Openproj
java -Xms128m -Xmx512m -Duser.home=[drive: Openproj]\Openproj -jar openproj.jar 2>Openproj_bugs.txt
I use 2 separate folders (directories), one for Java and one for OpenProj with the files created by this program. The references used in the cmd file;

  • [drive: java] = drive with Java
  • [drive: Openproj] = drive with Openproj

should be replaced by real drive letters. Save the file and rename it to openproj.cmd or use/adjust openproj.cmd from the distribution. This file is copied to the Openproj directory. Furthermore, different paths?, adjust according to your needs.
The program wants to store the user files in the default directory "ODIN\My Documents", however you can choose your own directory but it cannot be saved as preference. The helppage doesn't work because it can't find our browser.

Create a new program object or copy it from the file below. Specify the path and file name: "[drive: Openproj\Openproj\openproj.cmd". In the tabpage Session check the boxes "OS/2 window", "Running as an icon" and "Close Window to end program". In the tabpage General you can enter the name "OpenProj".

Parameters / options explained
  • The "-Xms128m" specify the initial size of the memory allocation pool.
  • The "-Xmx512m" indicates the maximum limit of the used memory.
  • The statement "-Duser.home=[drive: Openproj]\Openproj" will ensure that OpenProj will save all necessary files in own directory instead of saving them in the home directory.
  • The addition "2>Openproj_bugs.txt" ensures that errors are saved in the file "Openproj_bugs.txt". The 2 in "2>" is not a typo!

Download
In the file you can find the above command file (all drive letters are on set to C:) and an OS/2 Openproj icon: Openproj-eCS.zip.
