CLASSPATH and packages
Posted on 1998-06-09
Im about going out of my skull here..
First off im using the JDK1.1.5 on a WIN95 system (single user)
I have been working with Java for a while now however I have never created my own packages or really even had to set the CLASSPATH. I've only imported the API packages up til now.
Now I've wanted to experiement with creating my own packages and using packages that I have received from other people (I found one that was written by Jim Buzbee called houseblend that allows you to rotate and manupulate fonts, etc...its at www.nyx.net/~jbuzbee/font.html (for a plug))
anyway using this as an example of my problem...
the package is called houseblend
I have set up my CLASSPATH as the following:
set CLASSPATH=c:\jdk115\;c:\jd
and have tried putting the package houseblend in a directory off both of these directories the class file that is my concern is called HersheyFont.class
so the path to that file is c:\jdk115\houseblend\Hersh
The HersheyFont.java file compiles without a hitch
but when I try to compile the test.java class that came with the package it gives me the following error which leads me to believe that I have somehow specified the CLASSPATH or the directory structure wrong:
test.java:19: Package houseblend not found in import
OR
if i have the period "." at the front of my classpath the compiler would give me this error:
error: File.\HersheyFont.class does not contain type HersheyFont as expected but type houseblend.HersheyFont.
Please remove the file or make sure that it appears in the correct subdirectory of the class path
Obviously something is messed up with my classpath or subdirectories (very few errors are THAT specific but I still cant seem to figure it out)
The test.java has multiple import statements one of which is: import houseblend.*;
and there is a package statement in the HersheyFont class
Any comments or questions would be greatly appreciated
I'll assign it as easy for now (it sure SEEMS easy... the documentation I have read about creating packages is straightforward)
I think Im in the forest so deep that i cant see the trees

test.java is located in the same directory as the package itself
so in the example situation it is located in the c:\jdk115\myjava\classes\h
font package (and it imports the package)
If I remove the package statement from the source code (and the import) and run the test class it works (because its in the same directory)
but id really like to know what im missing here

Classes which belong to different packages should not really live in the same directory. If the class belongs to a package, then its directory is pretty much defined (relative to CLASSPATH directory). I am not exactly sure where you should put the class not belonging to any package which imports other packages. Try either putting test.java into some package (houseblend or your own) or try moving it out of houseblend directory (e.g. one level up).
