Posted: Jul 27, 2003 8:24 AM

Hi,
I would like to write a app. that when oppen:
- log details such:
* Date,
* Time,
* Events such Errors...
Each time the program run it should create a new log file, but the previous one should remain in....
After I should be able to read the files with a Text editor (xx.text).

Many thanks for your help
Best wishes for your future.

Hi.
Try the following code, it will catch any error and then write it to a textfile.


try
{
   //lots of code where something can go wrong
}
catch(Exception e)
{
  
   BufferedWriter bw = new BufferedWriter(new FileWriter(file));
   PrintWriter outFile = new PrintWriter(bw,true);
   outFile.print(e);

   //then also write the date and time, I'm sure
   //you can find it yourself how to fix the rest :-)
   outFile.print(date and time variable);

   outFile.close(); 

}

To do logging properly, take a look at Apache's log4j.
