retaining comment in properties file

I'm loading properties file using properties api and saving it back with changes using same api...but if any comments were present in the file (preceded by #)..are getting lost if i save back.

Is their any way to retain the comments which were present in the file while saving back.

Thanks,

AFAIK, there is no way to retain the header or comments. As a workaround, you can use a dummy property :

---- myfile.properties ----
#This is a comment
myvalue1=foo
myvalue2=bar
__MY_COMMENT__=This is a comment \
               that spans on 3 \
               lines

HTH,

Default implementation of java.util.Properties ignores all comments. You could create wrapper that will replace all first '#' or '!' chars in property file with unique strings like:
#comment
comment206467=comment

before reading property file and will replace all this properties names with '#' or '!' symbols back when property file will be stored.
