java - Jar file ran by cron doesn't write his own log -


i have simple java program (java version 1.7), email sender, , want log events during running. decided use org.apache.log4j.logger this. created log4j.properties file contains following:

log4j.rootlogger=info, file log4j.appender.file=org.apache.log4j.rollingfileappender log4j.appender.file.file=autoemail.log log4j.appender.file.maxfilesize=2mb log4j.appender.file.maxbackupindex=10 log4j.appender.file.layout=org.apache.log4j.patternlayout log4j.appender.file.layout.conversionpattern=%d{dd/mm/yyyy hh:mm:ss,sss} %5p %c{1}:%l - %m%n log4j.appender.file.encoding=utf-8

this how load configuration:

propertyconfigurator.configure(cl.getresource("resources/log4j.properties")); logger = logger.getlogger(""); logger.info("auto email sending started...");

where cl classloader. when run eclipse on localhost, works desired, log file has been created if didn't exist, , on next run appended.

then wanted run email sender program automatically every day @ 7 am. created scheduled cron job, executes following:

java -jar /var/projects/autoemail/autoemail.jar  2>> /var/projects/autoemail/autoemail.err

on first run worked fine, log file had been created , info or error had been inserted, since program doesn't write event it. jar file runs, because can see sent emails. when started searching reason, , ran command, showed me permission denied error. checked rights of log file, , was: rw-rw-r--. modified, @ last rwxrwxrwx, still doesn't write log, , can't see error message in syslog file. owner doesn't need sudo right, think. btw server ubuntu 13/04.

does have idea of can wrong, still needed, or have do?

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
