Servlet won't write logs

LeperKing

Hi All,

I developing java servlets using eclipse with Tomcat plugin on a tomcat server on my PC. I'm trying to get the log method to work, but nothing is in the server directory. EG

this.log("This is a message in the log.\n);

Anyone any ideas?

Thanks,
LK.

Never used java servlets or Tomcat but problems like this in a web environment normally come down to permissions. Does the user the webserver is running as have write permissions to the directory you expect to see the log file in?

I'm not really an experienced Java programmer myself, but I generally use my own debugging function, something like the following:

private void debug(String strVariableName, String strValue)
{
        try
	{
		//Open the file in 'append' mode.
	    	BufferedWriter out = new BufferedWriter(new FileWriter("D://somepath//somefile.log", true));
		    	
		out.write("The vaule of "+ strVariableName +" was: " + strValue +"\r\n") ;
		    	
	 	out.close() ;
	}catch(IOException exp){
		System.err.println("ERROR:" + exp.toString());
	}catch(Exception ex){
		System.err.println(ex.toString());
	}
}

Hi,

You have a number of options

(1) Log4j

(2) Or used the log method from the ServletContext

Thanks folks problem sorted.

System.out.println() goes to the tomcat logs, which is all i need.
