[How to set Relative Path for Jasper Report]

Hello Everyone,

My small Swing Project is ready to deploy. Now I realised that i had used absolute path for Jasper Report which will create problem on client side I guess.

So I want to use relative path for that i searched but didnot get any appropriate answer.

Here is code 

             DefaultTableModel jtm2 = (DefaultTableModel) jTable2.getModel();
            JRDataSource dataSource = new JRTableModelDataSource(jtm2);
            JasperPrint jprint = JasperFillManager.fillReport("E:\Swing Project\SCMPayBoard\src\scmpayboard\EmpReport.jasper", null, dataSource);
            JasperViewer.viewReport(jprint, false);

How do i change the path E: drive into relative so where ever user install, it wont create problem.

I searched the syntax (.) (..) single dot and double dot and tried various variation but no result.

Please guide me

JDBC Driver -net.ucanaccess.jdbc.UcanaccessDriver

JDBC URL- jdbc:ucanaccessE:ProjectPayBoardDatabaseDbTest1.accdb
