Hi everybody!

Im developing a web application with JSP, and im finding this problem.
Im trying to create a text file with some information. This is an
extraction of the code im using:

....

import java.io.BufferedWriter;
import java.io.OutputStreamWriter;
import java.io.FileOutputStream;

....

    public void toLogFile(String fileNameIn, String comentarioIn){
        String path = "";
        try{
            BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(new
FileOutputStream(path + fileNameIn, true)));
            String resultado = "";
            bw.write("PEDIDO: ");
            bw.newLine();
            bw.write("Cliente: " + getClientName());
            bw.newLine();

// code for finding what i want to write in the text file

            if (suReferencia != "") resultado += "Referencia de cliente: " +
suReferencia + "\n";
            resultado += "Comentarios: " +
Conversor.procesaComentario(comentarioIn) + "\n";
            for(int i = 0; i < numDetalles; i++){
                resultado += " - " + detalles[i].detalleToString() + "\n";
            }
// Found what i want to write. Now i write it in the text file.

            bw.write(resultado);
            bw.newLine();
            bw.flush();
            bw.close();
        }
        catch(Exception e){
            System.err.println("---Logger Exception---");
            System.err.println("Mensaje: " + e);
        }
    }

This works fine in my development computer, whose operating system is
Windows XP, but when i try it in my production computer, with UNIX
instead of Windows, the JSP that calls the method "toLogFile" returns
this error (in spanish):

In english, "No se puede compilar la clase para JSP", would be "the
class cannot be compiled for JSP".

Does anybody have an idea of what can be happening? I think the error
can be related with the Windows/UNIX difference, but im not sure.

Thank you in advance, and sorry for writing too much code and error
text.
Greetings
