The deployer places the sca-contibution jar under the repository and adds an EmbeddedRuntimeGBean to the configuration. When the configuration is started, the EmbeddedRuntimeGBean deploys the sca-contribution into EmbeddedSCADomain. The plugin has servlet-host implementations for Geronimo-Tomcat and Geronimo-Jetty so that the services exposed with webservice binding use the webcontainer in Geronimo. Proxies to SCA services are obtained through the SCADomain made available by the EmbeddedSCADomainGBean. > On Oct 3, 2008, at 2:57 AM, ant elder wrote: > > I'd like to start spending more time actively working on the Tuscany > Geronimo integration and having that more support the SCA JEE specification > (see: [1]).
