That won't quite do it if you want only the names of matching files.
The following will do it for you without xargs:

find <dir> -type f [-name <file name pattern] -exec grep -l <pattern> {} \;

which is almost the same as

find <dir> -type f [-name <file name pattern] -exec grep -q <pattern> {} 
\; -print

grep -l prints out just the name of any file containing the pattern.
grep -q prints nothing but returns 0 for matching files

-exec is a conditional operator; if the command called by -exec returns
0, -exec returns TRUE.  This can be useful if you wanted an action
other than -print, say -delete for example.
