Executing java .jar from UNIX script

Shell Programming and Scripting
1

I have a .jar placed in my Unix directory. The .jar creates a .csv file .I want to execute the .jar and place the output file in a target Unix directory.
The Unix Script is as follows. The issue that i am facing is that the file is not being placed in the REPORTDIR=/cdunix/IQNavigator/wrk instead it is placed in the directory where the .jar is present

#!/bin/sh

It is kind of hard to guess at why a java script is placing a file in the wrong directory if you don't show us the java code...

Below is the java code. Actually i am not so good in java or unix. The java code was initially created by someone else to generate a .xls file and then the shell script would place the file into the right directory(which was working perfectly fine).
Then i was supposed to make some changes in the java code to create a .csv file so i created the below code with someone's help .The code is creating the .csv file as desired but now the generated file is not being placed in the right directory.

the initial code was as below------

public class Int2TextUtility
{

    public Int2TextUtility()
    {
    }

    public static void main(String args[])
    {
        if(args.length < 2)
        {
            System.err.println("Usage: <java class name> <report path> <file name>");
            System.exit(1);
        }
        SimpleDateFormat dateFormat = new SimpleDateFormat("MMddyyyy");
        String date = dateFormat.format(new Date());
        String reportPath = args[0];
        String fileName = (new StringBuilder(String.valueOf(args[1]))).append(date).append(".xls").toString();
        System.out.println((new StringBuilder("report file name ")).append(fileName).toString());
        String query = prepareQuery();
        System.out.println("Preparing connection..");
        Connection conn = getConnection();
        System.out.println((new StringBuilder("Got connection..")).append(conn).toString());
        try

            writeToExcel(conn, query, reportPath, fileName);
