## org.apache.cayenne.remote.hessian.service
Class HessianServlet

    java.lang.Object
      javax.servlet.GenericServlet
          com.caucho.hessian.server.HessianServlet
              org.apache.cayenne.remote.hessian.service.HessianServlet

All Implemented Interfaces:
  Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig

    public class HessianServlet

extends com.caucho.hessian.server.HessianServlet

An extension of the `com.caucho.hessian.server.HessianServlet` that installs default Cayenne handlers, simplifying `web.xml` configuration. Here is a sample configuration:

            <servlet>
              <servlet-name>cayenne</servlet-name>
              <servlet-class>org.apache.cayenne.remote.hessian.service.HessianServlet</servlet-class>
            </servlet>

            <servlet-mapping>
              <servlet-name>cayenne</servlet-name>
              <url-pattern>/cayenne</url-pattern>
            </servlet-mapping>

Custom service class and interface can be specified in a manner compatible with Hessian recommendations, namely via service-class and api-class servlet parameters.
