Hi,

I am getting an Invalid class exception for some reason.
I have an array that is sent over the socket.

I will be sending this serializable object in a loop, each time sending a different array.

The program runs fine for some time and suddenly crashes saying Invalid class Exception.
I dont understand why it executes for some part of the loop and why it crashes in between.

I have the following program.

import java.io.*;

public class GridServ implements java.io.Serializable{

private String serverArray[][];
private int noOfRows;
private int noOfCols;

public GridServ(){
serverArray = new String[50][50];
noOfRows = 0;
noOfCols = 0;
}

public void setGrid(String array[][]){
for (int i=0;i
for (int j=0;j
serverArray[i][j]=array[i][j];
}

public void setSize(int rows, int cols){
noOfRows = rows;
noOfCols = cols;
}

public void writeToFile(){
String outGrid = "/home/vsangam/grid/Grid.txt";
try{
BufferedWriter out = new BufferedWriter(new OutputStreamWriter(new
FileOutputStream(outGrid, false)));
for (int i=0;i
for (int j=0;j
out.write(serverArray[i][j]+" ");
out.newLine();
}
out.close();
}catch(Exception e){System.out.println("Exception while writing to file:GridServ.writeToFile() " +e);}



}

I my main program, I create a GridServ object and call the setGrid(array [][]) function.
In my receiving program, I just call the writeToFile() function that writes the grid array to a file.

It runs fine for some part of the loop, but the program crashes after sometime.
can anybody please explain why ??


Thanks,
Venkatesh.
