XML : Warning in log4j xml file

      <?xml version="1.0" encoding="UTF-8"?>      <!DOCTYPE log4j:configuration SYSTEM "log4j.dtd" >      <log4j:configuration>    

In the second line of above code, i am getting the following warning :(

The file cannot be validated as the XML definition "<>\src\main\java\log4j.dtd (The system cannot find the file specified)" that is specified as describing the syntax of the file cannot be located

Someone please suggest the solution.

Thanks in advance
