i followed blog here.. http://hwellmann.blogspot.com/2012/11/logging-with-slf4j-and-logback-in.html

am using following jars slf4j: jul-to-slf4j-1.7.5.jar, slf4j-api-1.7.5.jar

and in logging.properties

handlers = org.slf4j.bridge.slf4jbridgehandler

i not getting mixed messages on start of tomcat. not printing tomcat format, throws handler error

below snippet of logs

i have been on problem days, tried lot of combinations, couldnt find luck it.

thanks in advance!

just create or edit catalina_home/bin/setenv.sh linux:

classpath=$catalina_home/bin/jul-to-slf4j-1.7.5.jar:\   $catalina_home/bin/slf4j-api-1.7.5.jar

or catalina_home\bin\setenv.bat windows:

set classpath=%catalina_home%\bin\jul-to-slf4j-1.7.5.jar;^ %catalina_home%\bin\slf4j-api-1.7.5.jar

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...
