Stand-alone references

Stand-alone references allow a Java™ program to invoke SCA components or imports.

Services that are not defined as SCA components (for example, JavaServer Pages) can still invoke SCA components; they do so through the use of stand-alone references. Stand-alone references contain partner references that identify the components to call. On their own, stand-alone references do not have any implementation or interface.

You can use the palette in the assembly editor to create stand-alone references in the module assembly. You can add partner references to the stand-alone references and wire them to target components or target imports.

You can only use one stand-alone references node in each assembly diagram.
