Hello everybody :)
Just 2 hours ago I downloaded trial JExcel from


I joined the lib folder to my IDE (JBuilder 8) etc... But the thing is I can't compile any code like:
Java Code:
Application app = new Application();
        File xlsFile = new File("Workbook.xls");
        Workbook workbook = app.openWorkbook(xlsFile);
        Worksheet s = workbook.getWorksheet(0);
        Cell cell = s.getCell("C4");

As soon as I push Run error appears like a...
log4j:WARN No appenders could be found for logger (com.jniwrapper.DefaultLibraryLoader).

log4j:WARN Please initialize the log4j system properly.
I don't understand the lines mean :confused:

The code like
Java Code:
import com.jniwrapper.UInt32;
import com.jniwrapper.win32.ole.OleFunctions;
import com.jniwrapper.win32.com.types.*;
import com.jniwrapper.win32.jexcel.Application;
import java.io.File;
import com.jniwrapper.win32.jexcel.*;
import java.io.*;
import com.jniwrapper.DefaultLibraryLoader;
import com.jniwrapper.Library;
...is OK (no red underlining)
If you know the problem is please help...
