Using user-defined classes in WM Java Service

hi all,
i want to use some user defined java classes in my java service .where can i put java classes (in which folder) so that those are available to write custom java service…
thanks in advance

Basically put your jar file (contains new classes) in c:\webmetods6\IntegrationServer\lib\jars folder and restart IS.Then IS will locate those news classes and you can start importing classes when creating java services.
