Reg :: Warning While Printing

[Sumit Adhikari]

Dear Developers,

   I am having some errors while I plot some data and print to pdf file.
Attached is the logfile for reference.
   I am particularly worried about following two lines :

   log4j:WARN No appenders could be found for logger
(org.apache.xmlgraphics.image.loader.spi.ImageImplRegistry).
   log4j:WARN Please initialize the log4j system properly.

   Please let me know what will be the prescription for this messages (Or
for this warning I must not be bothered).

Regards,
--
