An apparatus, system, and method are disclosed for supporting service components written in non-native runtime code in a Service Component Architecture (“SCA”). A read module is included to read an implementation type definition having metadata identifying executable code that executes a new implementation type. A receive module is included to detect a dynamic service call to a service component having the new implementation type. The dynamic service call is defined in an SCA message from a calling SCA component. A passing module is included to pass the dynamic service call to a predefined SCA implementation handler associated with the new implementation type. The SCA implementation handler includes native runtime code and implementation logic for executing the dynamic service call by executing non-native runtime code that returns a result to the SCA implementation handler. A packaging module packages the result in an SCA return message to the calling SCA component.
