Re: Console Output Not Going Anywhere

Sun, 09 Aug 2009 09:15:03 -0700

I had added a few lines from the deployed version trying to get it to work, but, on my tomcat5.5 system, this original code: 

public class AppInitializer implements ServletContextListener
   {
   public void contextInitialized(ServletContextEvent e)
       {
       log.write("AppInitializer::ContextInitialized entrance");

       ServletContext sc= e.getServletContext();
log.write("AppInitializer::ContextInitializer: context name='" + sc.getServletContextName() + "'"); // log.write("AppInitializer::ContextInitializer: context path='" + sc.getContextPath() + "'"); 

       // Order is important!!  Need the database
       initDB(sc);
       initAppInfo(sc);
       initXRef(sc);
log.write("AppInitializer::Seems to have run OK\n*******************\n"); 
       }


using a "log.write" class/method with this in it:

   public void write(String msg)   // Need to do more with this later
{ // (e. g., timestamp, logging levels, etc.) 
       if(msg == null || msg.length() == 0)
           {
           System.err.println("<null>");
           return;
           }
if(msg.substring(0, 1).equals("\n") || (msg.length() > 5 && msg.substring(0, 4).equals("****")) || !AddTs) 
           System.err.println(msg);
       else
           System.err.println(getTimestamp() + ": " + msg);
       System.err.flush();
       }
(Not that, except for deciding whether or not to time stamp the entry, it is just using System.err.println to output the message) 
produces this in the log:

catalina_2009-07-18.log:AppInitializer::ContextInitialized entrance
ccatalina_2009-07-18.log:Jul 18 13:43:05: AppInitializer::ContextInitializer: context name='infoisland' catalina_2009-07-18.log:Jul 18 13:43:06: AppInitializer::Seems to have run OK

That makes sense, Tomcat 6 doesn't use commons logging by default

problem explained.
if you want tomcat to use commons logging, you could build the extras package

what class is Logger.getLogger(....), doesn't look like a tomcat class,
so, no, it wont show up in the tomcat configured logs.
Also, System.out/err only show up in the logs if you have swallowOutput
set AND it happens during a request.
ServletContextListener don't happen during servlet requests

ANY ideas why my console AND my log file are being sent to a black
hole?  BTW, I have also set and unset swallowOutput="true" multiple
times in my<Context>  tag.


Sorry, I should have mentioned that.  Yes, I've tried it both ways,
multiple times.  BTW, is that something new in Tomcat6?  I've never
seen it before now.

did you set

I'm trying to get Tomcat 6 up and working; didn't have this problem
on 5.

The code:

System.err.println

does not print to the log files.  With this logging.properties:
org.apache.catalina.core.ContainerBase.[Catalina].[info-dev].[/infoisland].level 
= ALL
org.apache.catalina.core.ContainerBase.[Catalina].[info-dev].handlers 
= 3info-dev.org.apache.juli.FileHandler

I get some exceptions, etc. in the info-dev.log file.  With this:
org.apache.catalina.core.ContainerBase.[Catalina].[info-dev].[/infoisland].level 
= ALL
org.apache.catalina.core.ContainerBase.[Catalina].[info-dev].[/infoisland].handlers 
= java.util.logging.ConsoleHandler

I get zero bytes.  In neither of the above cases to I get the
output from several System.err.println's or System.out.println's.
Can someone tell me how to find out where my console is going, or
how to redirect it?

TIA
