WebServices with CXF - Configuration files I

I'll show 2 basic configuration files: web.xml & my hibernate configuration file (mapping.cfg.xml)

<web-app version = "2.4" xmlns = "http://java.sun.com/xml/ns/j2ee" xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation = "http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> <display-name>Archetype Created Web Application</display-name> <context-param> <param-name>webAppRootKey</param-name> <param-value>my-web-app</param-value> </context-param> <!--Log4J Configuration --> <context-param> <param-name>log4jConfigLocation</param-name> <param-value>/WEB-INF/conf/log4j/log4j-config.xml</param-value> </context-param> <!--Spring Context Configuration --> <context-param> <param-name>contextConfigLocation</param-name> <param-value> /WEB-INF/conf/spring/daoApplicationContext.xml, /WEB-INF/conf/spring/serviceApplicationContext.xml, /WEB-INF/conf/cxf/cxf-services.xml </param-value> </context-param> <!--Log4J Listener --> <listener> <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class> </listener> <!--Spring Context Listener --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!--Servlet Declarations --> <servlet> <servlet-name>webApplicationServlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/conf/spring/webApplicationContext.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet> <display-name>CXF Servlet</display-name> <servlet-name>CXFServlet</servlet-name> <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>CXFServlet</servlet-name> <url-pattern>/services/*</url-pattern> </servlet-mapping> <!--Servlet Mappings --> <servlet-mapping> <servlet-name>webApplicationServlet</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping> <!--Session Time-out in minutes --> <session-config> <session-timeout>30</session-timeout> </session-config> <!--Welcome file --> <welcome-file-list> <welcome-file>/index.jsp</welcome-file> </welcome-file-list> <!--Reference to a my DB Conection --> <resource-ref> <description>DB Connection</description> <res-ref-name>jdbc/bookStoreDS</res-ref-name> <res-type>javax.sql.DataSource</res-type> <res-auth>Container</res-auth> <res-sharing-scope>Shareable</res-sharing-scope> </resource-ref> </web-app>

As you noticed I'm using Spring MVC (see webApplicationServlet), but for now let's focus on Spring and CXF:

My 3 main configuration files are listed here, where the 3rd one is for CXF (really obvious file name) and to enable Apache CXF is so simple, Did you remember XFire? <!--Spring Context Configuration --> <context-param> <param-name>contextConfigLocation</param-name> <param-value> /WEB-INF/conf/spring/daoApplicationContext.xml, /WEB-INF/conf/spring/serviceApplicationContext.xml, /WEB-INF/conf/cxf/cxf-services.xml </param-value> </context-param> ... ... ... <servlet> <display-name>CXF Servlet</display-name> <servlet-name>CXFServlet</servlet-name> <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>CXFServlet</servlet-name> <url-pattern>/services/*</url-pattern> </servlet-mapping>

This is not rocket science! So simple :)


Now let's see my (small) Hibernate configuration file (which I just called mapping.cfg.xml) <hibernate-configuration> <session-factory> <mapping class="mx.com.mylibrary.core.persistence.domain.Author"/> <mapping class="mx.com.mylibrary.core.persistence.domain.Book"/> <mapping class="mx.com.mylibrary.core.persistence.domain.Editor"/> </session-factory> </hibernate-configuration> Instead of using resource=, I'm using class=, because I don't have any hbm.xml file. I'm mapping directly to the class (due to Java Annotations, my mapping it was declared on each POJO).

Now what do you think? Is not as complex as looks like.
