Question

From the command line, how do I set the Java CLASSPATH option to point to one or more directories containing multiple jar file? Are there wildcards for recursive directory and sub-directory support?

(My JAR files are sorted in several sub-directories.)

Answer 1

If you are using Java 6 or higher you can use wildcards of this form:

java -classpath ".;c:\mylibs\*;c:\extlibs\*" MyApp

If you would like to add all subdirectories: lib\a\, lib\b\, lib\c\, there is no mechanism for this in except:

java -classpath ".;c:\lib\a\*;c:\lib\b\*;c:\lib\c\*" MyApp

There is nothing like lib\*\* or lib\** wildcard for the kind of job you want to be done.
