Here is what we do to redirect stdout in Resin. The servlet is set to
<load-on-startup/> so that the init() method is called on server start.
public class HomePath extends HttpServlet
{
public static final String STDOUT_PATH_KEY =
"com.cinteractive.ps2.log.stdout";
private PrintStream _stdout = null;
protected void doGet( HttpServletRequest req, HttpServletResponse res )
throws ServletException, IOException
{
// print version and app configuration information
}
public void init( ServletConfig config )
throws ServletException
{
super.init( config );
// lots more initialization stuff here
// ....
initStdout( config );
}
private void initStdout( ServletConfig config )
throws ServletException
{
// get the log file path info from the config properties.
final String logFileName = config.getInitParameter( STDOUT_PATH_KEY );
if( logFileName == null )
return;
// create the logfile, and open it for write on System.out.println.
try
{
final File file = new File( logFileName );
file.createNewFile();// create if it doesn't already exist
_stdout = new PrintStream( new FileOutputStream( file.getPath(), true
) );
System.setOut( _stdout );
}
catch( IOException e )
{
throw new ServletException( "Error setting System.out.", e );
}
}
}

Subject: capturing standard out
JSP list,
Could anyone help me? I am attempting to run a java class (which
has a main method) from within a jsp page, and display the
output, which is being sent to System.out.println. Is this
possible, I feel that it should be, but my attempts have all
fallen flat.
If this is not simple to do with jsp, could anyone advise a
better way to run a java class and capture the output in a
browser? I have tried perl but can't seem to get hold of the
output.
TIA
Chris Probert
