Contains classes that represent Web service invocations as threadsafe, reusable objects. This approach is similar to the JDBC Object support in the Spring framework (see the `org.springframework.jdbc.object` package).

This higher level of Web service abstraction depends on the lower-level abstraction in the `org.springframework.jdbc.core` package. Exceptions thrown are as in the `org.springframework.dao` package, meaning that code using this package does not need to implement JDBC or RDBMS-specific error handling.
