Deep understanding of Java classpath is something that is too often neglected. I won’t write an article about classpath, internet is full of readings about it :
- How Classes are Found at java.sun.com
- Classpath (Java) page from Wikipedia
- Classpath entry in the Java Glossary
- Java Tip 105: Mastering the classpath with JWhich
JWhich provides a command line interface and a Java api where jcfind only has command line interface and is written in python.
I prefer to use jcfind from the command line because it’s really faster than Which4j and the command line is more practical. In Java software, I use the JWhich API that is really easy to use. The big drawback of using Which4j from command line is that you must provide a full class name, using it’s API you can search for a class simple name.
