Examples of org.apache.geronimo.kernel.Kernel.loadGBean()

org.apache.geronimo.kernel.Kernel.loadGBean()
Load a specific GBean into this kernel. This is intended for applications that are embedding the kernel. @param gbeanData the GBean to load @param classLoader the class loader to use to load the gbean @throws org.apache.geronimo.kernel.GBeanAlreadyExistsException if the name is already used @throws org.apache.geronimo.kernel.InternalKernelException if there is a problem during registration
