I am having more than 25 jar files how to add all of them in a classpath?

Include all the directories which contain . class files and JAR files when setting the CLASSPATH. You need to load a class that is not present in the current directory or any sub-directories. You need to load a class that is not in a location specified by the extensions mechanism.
To check our CLASSPATH on Windows we can open a command prompt and type echo %CLASSPATH%. To check it on a Mac you need to open a terminal and type echo $CLASSPATH.
If all the jar files are in the same folder, as of jdk6, Java supports classpath wildcards. http://download.oracle.com/javase/6/docs/technotes/tools/windows/classpath.html
So you can use something like,
/path/to/jar/*
Also consider having a separate classpath for each project.

Separate them with a colon / semicolon (: / ;) on *nix / win
But it would be way easier to use an IDE (Eclipse, NetBeans) to handle the classpath for you.
