Thanks for your reply. I tried out NDC and is working fine.

But I could not use MDC. It gave the following error:

java.lang.NoSuchMethodError: org.apache.log4j.spi.LoggingEvent.getMDC

I am using log4j-1.3alpha0.jar and a jdbcappender which extends log4j (

My code snippet is:

*Logger loggerObj = LoggerFactory.getLogger("UsageLogger");*



*loggerObj.info("MDC test");*



My log4j.xml entry is:

*<param **name="sql" value="INSERT INTO LOGSTAB (id, prio, cat, thread, msg,
throwable, ndc, mdc, the_timestamp) VALUES (FELIXLOGS_SEQ.NEXTVAL,@INC@,
'@PRIO@', '@CAT@', '@THREAD@', '@MSG@', '@THROWABLE@', '@NDC@',

Why is it happening? I understand that you can store only one value in the
database using NDC. Please correct me if I am wrong.

Thanks & Regards
