To deploy your custom field extensions, the Java code must be compiled and the resulting *.class files must be uploaded to the appropriate sub-directory under ~/CB-.../tomcat/webapps/cb/WEB-INF/classes/..., where the sub-directory is the equivalent of the extension's package name.

If you have multiple custom field extensions, along with custom Wiki Plugins, Workflow Actions, and so on, you may choose to pack your custom classes into one Java archive (*.jar), along with your custom language resource files, and put that JAR file into the ~/CB-.../tomcat/webapps/cb/WEB-INF/lib directory.

Restart Codebeamer for your newly deployed classes to be loaded.
