Hey Saravana,

The new NGP file shoud be kept in the place where
NGramProfile.java is 
placed i.e where all other ngp files are present.
The ant script will then copy all the .class , ngp files, 
langmappings.properties file in the language-identifier.jar

...../nutch0.9      the nutch directory for creating new ngp
file

java -classpath build/language-identifier/language-
identifier.jar:build/language-identifier/classes/org/apache/
nutch/analysis/lang/NGramProfile
-create ta
sample.ta.utf8.txt UTF8 and i  got the error as follows

Exception in thread "main"
java.lang.NoClassDefFoundError: loaded class
NGramProfile was in fact named
org.apache.nutch.analysis.lang.NGramProfile
  at java.lang.VMClassLoader.defineClass(libgcj.so.7)
  at java.lang.ClassLoader.defineClass(libgcj.so.7)
  at
java.security.SecureClassLoader.defineClass(libgcj.so.7)

The best way is to use the following command:
