Hello all,
I'm new to this forum.

I have a problem in reading data from .properties file...

Follow is my properties file...

log4j.properties

log4j.rootLogger=warn, file, mail

log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.maxFileSize=100KB
log4j.appender.file.maxBackupIndex=5
log4j.appender.file.File=D:\log.txt
log4j.appender.file.threshold=info
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n

#email appender
log4j.appender.mail=org.apache.log4j.net.SMTPAppender
#defines how othen emails are send
log4j.appender.mail.BufferSize=1
log4j.appender.mail.SMTPHost="smtp.Honeywell.com"
log4j.appender.mail.From=PraveenKumar.J@Honeywell.com
log4j.appender.mail.To=PraveenKumar.J@Honeywell.com
log4j.appender.mail.Subject=Log ...
log4j.appender.mail.threshold=error
log4j.appender.mail.layout=org.apache.log4j.PatternLayout
log4j.appender.mail.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n
--------------------------------------------------------------------------------------------------


I want to access file path given in .properties file..
I'm coding like this...

Properties props = new Properties();
String p=props.getProperty("file.FILE");

The above code is not getting me the string.. it shows null value...

Any solution...?

Thanks in advance......
