I want to figure out how can I run a java program which demand different types parameters to be passed. Here the instructions of the author's program :

RUN : 

$ cd wmart/work/
$ java -jar WMartSimulator <seed> <maxDays> <daysForward> <membersFile> [<parameters>]

Java may require sufficient options depending on your environment. For example:

$ java -d64 -Xms1G -Xmx30G -Djava.library.path=/usr/ilog/cplex/bin/x86-64_debian4.0_4.1:/usr/local/lib -jar WMartSimulator.jar 0 30 7 member/type1.csv demandfile=demand/trial.csv\;demand/trial.csv:logdir=result/trial-type1

I've tried to execute the program by mapping his specific instructions to my owns. And here is what I've done :

In the program arguments of eclipse, I've put :

0 30 7 bin/work/member/type1.csv "demandfile=bin/work/demand/trial.csv"

And the VM arguments :

-Djava.library.path="C:\Program Files (x86)\LPSolve IDE\LpSolveIDE.exe"

After setting them up I got the following general description of my error :

java.lang.NullPointerException
    at edu.iw.mace.environment.Settings.<init>(Settings.java:69)
    at edu.iw.mace.environment.Market.<init>(Market.java:94)
    at edu.iw.mace.environment.Market.<init>(Market.java:79)
    at org.wmart.core.WBoard.<init>(WBoard.java:67)
    at org.wmart.core.WAuctioneer.initialize(WAuctioneer.java:52)
    at org.wmart.core.WMart.setupAuctioneers(WMart.java:1339)
    at org.wmart.core.WMart.<init>(WMart.java:112)
    at org.wmart.core.WMartSimulator.<init>(WMartSimulator.java:83)
    at org.wmart.core.WMartSimulator.main(WMartSimulator.java:47)

The corresponding bloc codes of Settings.java:69 is :

public Settings() throws FactoryException, MaceException {

        try {
            config = new PropertiesConfiguration(PROPERTIES_FILE);
        } catch (ConfigurationException e) {
            log.error(e.fillInStackTrace());
        }
        config.setAutoSave(true);// line 69

        initProperties();
    }

I wonder if I have followed correctly what it is prescribed in the author's website : https://github.com/ikfj/wmart/#run

Could you tell what is the wrong thing in my configuration ?. And also, if you can give me the specific documentation that deals with those specific problems.

    What's the complete error message? as you can see yourself `edu.iw.mace.environment.Settings.(Settings.java:69)` really does not give any information about the actual problem. – Joni Nov 08 '13 at 19:34
  • The java.library.path property shouldn't point to a file, but to a directory (or a set of directories) – JB Nizet Nov 08 '13 at 21:20
