Take a look there +first. + +If you want to try out the CRUD implementation type that this sample provides +please see the implementation-crud sample that provides the necessary client +code to bring up an application that uses this implementation extension. + +Sample Overview +--------------- +This sample contains a CRUD implementation type as an example of how to create +new implementation types. Components using this implementation type always +expose the same Create, Retrieve, Update and Delete interface. This sample +uses a singleton ResourceManager to perform the CRUD operations but of course +a real component would provide a real implementation. + +implementation-crud-extension/ + src/ + main/ + java/ + crud/ - implementation model interfaces + backend/ - fake component implementation + impl/ - implementations of the model interfaces + provider/ - runtime implementation + resources/ + META-INF/ + services/ - declares the extension + test/ + java/ + crud/ + CRUDTestCase.java - JUnit test case + resources/ + crud.composite - the SCA assembly used during unit testing + + build.xml - the Ant build file + pom.xml - the Maven build file + +Building The Sample Extension Using Ant +----------------------------------------- +With the binary distribution the sample extension can be built using Ant as +follows + +cd implementation-crud-extension +ant compile + +See the implementation-crud sample to run a sample that uses this +implementation extension. + +Building The Sample Using Maven +------------------------------------------- +With either the binary or source distributions the sample can be built +using Maven as follows. + +cd implementation-crud-extension +mvn + +Maven will also test that the sample extension built properly.
