Hi all,

Can you please tell me what advantages can i get in tomcat 6?
Can you please give me the differences between tomcat 5.1.17 and tomcat 6.x?

This will help !

Tomcat 5.x uses 2.4/2.0 Servlet/JSP Spec whereas Tomcat 6.x uses 2.5/2.1 Servlet/JSP spec (I don't know the exact sub version , please refer to documents )

Also, Tomcat 6 uses the NIO package, which has the potential for notable performance gains. Google for "Tomcat NIO" for more detail.

i have configured tomcat 6.0.18 in my test environment.
i can see that the SEVERE exceptions are going into localhost.2008-10-21.log file and these exceptions are not being printed in catalina.out file.

Is there a way, i can get these exceptions in catalina.out file too.
I also want to print the output of System.out.println into catalina.out, when my servlet call this System.out.println
Please suggest how it can be done
 
It is sorta covered in the JavaRanch Style Guide.
