Query

[Sunita Pahwa <sp...@ggn.aithent.com>]

Hi,
I am running XTest.class to see how XML files can be used for configuring log4j. This class can be found in following path

c:\jakarta-log4j-1.0.4\org\apache\log4j\xml\examples\XTest.class
I have installed log4j in c drive.

I run it by giving following command on command prompt:
java XTest sample1.xml
A run time error comes saying
log4j:ERROR Could not parse input stream [java.io.FileInputStream@218aa2].
java.lang.SecurityException: sealing violation

log4j:ERROR No appenders could be found for category (some.cat).

log4j:ERROR Please initialize the log4j system properly.

Can anybody tell what is the reason and solution?

Thanks in advance,
