Unhandled execption in EXE containing executable jar file.

[Jigar Naik]

Hi,

I have created one executable Jar file, to which i pass arguements. and from that executable jar file i have created exe file using jar 2 exe converter.

now that exe file is called by another application. and if my java program throws some execptions which i have not handled.

where can i find the execption ???

I have cheked windows EventViewer but could not find anything about the exe.

Simply logs the exception either on console or (more better) in file.

yeah... but what if i havent loged it... and i want to know what was the error... by default does jvm create log file somewhere.....

NO. As far as my knowledge and experience is concerned the unhandled error/exception goes to the default console. In my case its mostly CMD.

So basically it stays in a buffer...

I can't say where it stays exactly but the good practice will be to define checked custom exception class for your app and log them if they get thrown during execution.

Hi again,

I have done all the logging in my program.. but what i can see in the log file... that it has printed only first 2 statements... and rest of the statement were not printed in to the log files...

plus there has not been logged any error... i have done all the exception handling...

the only possibility i can see is that, there might be an internal error in log4j.
I have checked the log4j api, which says…

You can enable log4j internal logging by defining the log4j.configDebug variable.

http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/helpers/LogLog.html

I have enabled log4j loggin… but all the log statements are getting printed on console only… what I am trying is to print log4j internal logging statement in a separate file…

How do I do that ???

Below is my log4j.properties file.

log4j.rootLogger=DEBUG, daily
log4j.category.test.LoggingTest=DEBUG, daily
log4j.appender.daily=org.apache.log4j.DailyRollingFileAppender
log4j.appender.daily.File=E:\\InteractCRM\\PG_HOME\\logs\\PaymentGateway.log
log4j.appender.daily.layout=org.apache.log4j.PatternLayout
log4j.appender.daily.layout.ConversionPattern=%d{ISO8601} - %p [%t] %m%n
log4j.appender.daily.DatePattern='.'yyyy-MM-dd
log4j.debug=true

Can anybody help me out with this issue…
