Can JCover be used in case of EJBs, servlets etc?
For performance reasons JCover emits instrumentation code in your source minimally, but relies on native code to attach to the JVM when your application is running. JCover uses standard runtime switches to register itself with the JVM. If the host environment (EJB, Servlet Engine, etc.) supports these switches, then it should be possible to use JCover in that environment. Refer to topic Using JCover with Application Servers in help documentation for more information.
