Ethan,

	Please DO NOT "top post." Reply to another person's comments and 
questions "in-line" by placing your comments directly beneath those that 
you want to reply to. Your following this practice makes it much easier 
for other people to follow the discussion.

	OK, that is fine. In earlier versions of Tomcat (e.g., ver. 1.4.x), 
Tomcat's log file was called "catalina.out" (by default), not 
"localhost.log". Perhaps this name ("localhost.log") is peculiar to Red 
Hat distributions, such as Fedora Linux.

	OK, I erred. My email client did not properly display the entire email 
thread, just part of it. I apologize for seeming to be confrontational.

	I do? I "answer a lot of silly questions on this list?" Well, I will be 
damned. From time to time, I ask a few silly questions, too.

	I do not think that your question is "silly." Rather, I think that you 
need to learn a bit more about Tomcat, Java, and J2EE Web 
administration. I shall reiterate my earlier suggestion: make certain 
that your compiler and JRE are compatible by ensuring that they share 
the same version and are from the same creator, e.g., Sun, 
Blackdown.org, GNU, etc.

Cherif,

	What do you think? Please let us know.
