Thanks for replay. I'm sorry I have missed e-mail regard server .xml with romment removed. so I attached this file.
regard <Context path="" docBase="SIT/"/> i think that a mistake the correct form is in the file. "SIT" is name of my application. I don't able to match timestamp of error whith a request because i don't know how to trace all request in tomcat conaitner. How can do it? I have essentially only catalina_log (with error) and standard_out_log (in which i have application "SIT" stdout message).
