if excel file resource, can't use file manipulate rather resources, , believe read-only -- sure want do? instead load command line string tells program start looking file, or create property file tells first look.

if using jexcel can call workbook.getworkbook(java.io.inputstream is) , resource stream via class's getresourceasstream(...) method.

  public void getvalues() throws exception   {      workbook w1; //reads file      w1 = workbook.getworkbook(windagelogic.class.           getresourceasstream("/calculator/table1.xls") );      //...
