log4j

问题 I recently discovered that there was log4j extension for application insights. So following the example online I attempted to configure application insights and log4j to log items from my servlets living in an azure hosted tomcat. Well, the example seems very incomplete as it never makes mention of the key at all. From looking through the source I see an example (test?) that uses <param> within the log4j.xml but not much explanation of how to use or debug the actual logger. Does anyone out

问题 I often find myself adding either concatonated strings or using a string formatter in my debug statements in log4net and log4j should I surround these debug statements with an "if debug" block to stop myself from wasting resources by processing these parameters even though the debug statement will not be printed out? I would assume that checking if (isDebug) would be quicker and more efficient than having the string operations occuring, however it would lead to the program operating

问题 Is it possible to use a single log4j jar file in an tomcat 5.5 setup, where it can be used by multiple webapps and have seperate logging for each webapp? I have about 8 different webapps written where the only real difference between the log4j property files is the log filename. However if I attempt to move log4j from the webapp WEB-INF/lib directory to the tomcat5 shared/lib directory I run into problems. All the property files basically look the same as the one below, where I just set file

I've been using Java for my "home projects" for a while and now there's a need to make some of my projects available through the repositories like github or Google Code. As long as I'm the only developer for the project and as long as I always work in Eclipse, there are absolutely no questions about building and
