classpaths

[cameron <ca...@ogmios.ca>]

do classpaths automatically include subdirectories?

i.e. if I put /usr/local/tomcat into my classpath will I be able to find 
the classes defined in: /usr/local/tomcat/common/lib/ or 
/usr/local/tomcat/server/lib/, or do I have to specify each subdir as well?

The smart-ass answer is:
Yes, but only if your classes are defined as part of the common.lib package.

The helpful answer in the general case is:
No, you have to put each directory on your classpath separately.

The helpful answer for Tomcat specifically is:
Provided you're using a fairly recent Tomcat version, you don't have to 
worry about it.  Jars (*not* individual classes) that you put in either 
common/lib or server/lib will be picked up automatically by Tomcat when it 
starts -- that's why those directories are special and revered.  If you're 
not aware of the classloader issues involved with these, be sure to read 
and understand the oft-referenced guide:

http://jakarta.apache.org/tomcat/tomcat-4.1-doc/class-loader-howto.html

Happy trails,
justin

No, I don't believe they do.  

Besides, putting a ./lib directory into your classpath
won't do you any good - the jars underneath have to be
listed individually.  If you put a directory into the
classpath, there should only be .class files in it.
