i have a servlet and a CheckUser class. the CheckUser class and the servlet in different path.
so if the servlet want to use CheckUser class must import it..if commented out "import CheckUser;",
the compiler will say "can't find class CheckUser".

but in the CheckUser class, we did not use something like "package com.***.***"....we just put CheckUser
class in a path which is exist in the CLASSPATH...

in jdk 1.3 no problem. but the problem appears in jdk1.4..a error report: says '.' expected

as CEHJ said: Java classes are *always* in packages, even if there is no 'package' declaration...
so, i want to know which package CheckUser belongs to? because i didnot use 'package' declaration.....(if
CheckUser.java in path /home/com/***/ and /home/com/*** in the CLASSPATH)

The way to avoid the compiler error is to compile thus:
javac -sourcepath <path to CheckUser> <filename>.java
There is no need then to import CheckUser at all.

What I would say though, is that one ought to minimise source file dispersal. Think about the comment you made about packages. If there are the correct relations between packages, there is no need to yank together dispersed source.

Java 1.4 is a lot more strict about import statements...

Normally if you are sure that your file is in the classparh, never will be necesary to import'it.
