Need a working example of configuring log4j RollingFileAppender via properties -

-

i using log4j logging, , property file configuration. currently, log files big (3.5 gb large log file). think need use rollingfileappender - when log file continues grow overly large. believe have misconfigured it; have working example of configuring rollingfileappender?

for record, current configuration looks this:

log4j.appender.main_log.file=${catalina.base}/logs/webtop.log log4j.appender.main_log=org.apache.log4j.rollingfileappender log4j.appender.main_log.layout=com.mycompany.util.log.log4jsimplelayout log4j.appender.main_log.datepattern='.'yyyy-mm-dd log4j.appender.main_log.maxfilesize=10mb log4j.appender.main_log.maxbackupindex=99 log4j.appender.main_log.append=true log4j.rootcategory=all, main_log

an alternative rollingfileappender fine solution.

i believe have misconfigured it; have working example of configuring rollingfileappender?

this seems work fine me @mcherm. see below.

are sure using log4j.properties think are? try changing .file path see if log output goes new file. version of log4j using? i'm running 1.2.15.

hope helps.

i created following test program:

package com.j256.ormlite; import org.apache.log4j.logger; public class foo {     private static logger logger = logger.getlogger(foo.class);     public static void main(string[] args) {         (int x = 0; x < 10000000; x++) {             logger.error("goodness shouldn't happening right here!!!!");         }     } }

my log4j.properties file holds:

log4j.appender.main_log=org.apache.log4j.rollingfileappender log4j.appender.main_log.file=${catalina.base}/logs/webtop.log log4j.appender.main_log.layout=com.j256.ormlite.log4jsimplelayout log4j.appender.main_log.maxfilesize=10mb log4j.appender.main_log.maxbackupindex=5 log4j.appender.main_log.append=true log4j.rootcategory=all, main_log

notice removed datepattern wasn't valid rollingfileappender. layout is:

package com.j256.ormlite; import org.apache.log4j.spi.loggingevent; public class log4jsimplelayout extends org.apache.log4j.layout {     @override     public string format(loggingevent event) {         return "log message = " + event.getmessage().tostring() + "\n";     }     @override     public boolean ignoresthrowable() {         return true;     }     public void activateoptions() {     } }

running -dcatalina.base=/tmp/ files in /tmp/logs/ go index #5 , 10mb in size. if tune maxfilesize or maxbackupindex, adjusts appropriately.

C#: Application without a window or taskbar item (background app) that can still use Console.WriteLine() -

-
i'm trying create application adheres following: no taskbar no console or form window can utilize console.writeline() . (i.e. if executes app command prompt write console.) the problem if create windows form (or wpf) application can have there no taskbar, console or window show up, console.writeline() nothing. if create console app, writes console, can't figure out how hide (and if did hide it, write command prompt window?)... how do this? just create standard console application. callers responsibility hide window caused program (from how run c# console application console hidden ): system.diagnostics.processstartinfo start = new system.diagnostics.processstartinfo(); start.filename = dir + @"\myprocesstostart.exe"; start.windowstyle = system.diagnostics.processwindowstyle.hidden;

this question has answer here: how convert between big-endian , little-endian values in c++? 28 answers i've been looking around how convert big-endian little-endians. didn't find solve problem. seem there's many way can conversion. anyway following code works ok in big-endian system. how should write conversion function work on little-endian system well? this homework, since systems @ school running big-endian system. it's got curious , wanted make work on home computer also #include <iostream> #include <fstream> using namespace std; int main() { ifstream file; file.open("file.bin", ios::in | ios::binary); if(!file) cerr << "not able read" << endl; else { cout << "opened" << endl; int i_var; double d_var; while(!file.eof()) {...

i'm trying load particular private key encoded in binary der format ( pkcs#8 ) ruby. however, openssl::pkey won't recognize it. can make work doing console work , transforming pem so: openssl pkcs8 -inform der -in file.key -passin pass:xxxxxxxx >private_key.pem after this, key can correctly read. however, since whole process done in memory instead of writing , reading files. so question is: possible load private keys binary encoded der format ruby/openssl? thank time, fernando yes, can indirectly load pkcs#8 der-encoded private keys using ruby openssl. openssl::pkey::rsa.new handle pem-formatted pkcs#8, easy read binary der , convert pem-formatted string , load string. for example, these der-encoded private keys: $ openssl genrsa | openssl pkcs8 -topk8 -outform der \ -nocrypt -out pkcs8.key $ openssl genrsa | openssl pkcs8 -topk8 -outform der \ -v2 des3 -passout pass:secret -out pkcs8_des3.key you can this: require 'open...
