\subsection{Apache CXF}
	\begin{frame}{Introduction to Apache CXF}
		\begin{itemize}
		  \item an open-source framework for web services.
		  \item includes a broad feature set, not only API for RESTful web services
		  \item high performance
		  \item easy integration with Spring Framework
		\end{itemize}	
	\end{frame}
	
	\begin{frame}{Configuring services in container with Spring}
		To register services you need to add cxf servlet definition to web.xml
		\lstinputlisting[language=XML]{code/cxf_web.xml}
		And service bean to spring's beans.xml
		\lstinputlisting[language=XML]{code/cxf_beans.xml}
	\end{frame}
	
	\begin{frame}{Apache CXF REST client}
		You can use the service interfaces on client side to produce client which will act like proxy.
		
		\lstinputlisting[language=JAVA]{code/SampleApplication.java}
		
		Client definition in client's beans.xml
		\lstinputlisting[language=XML]{code/client_beans.xml}
	\end{frame}
	
	\begin{frame}{Interceptors in Apache CXF}
		Using interceptors you can read and manipulate request or response before it reach service implementation.
		
		\lstinputlisting[language=JAVA]{code/SampleInterceptor.java}
		
		Interceptor definition in beans.xml
		\lstinputlisting[language=XML]{code/cxf_interceptor.xml}
	\end{frame}
	
	\begin{frame}{Providers in Apache CXF}
		You can use built-in JAXB or Jackson providers for JSON/XML serialization or create a custom one.
		  
		\lstinputlisting[language=JAVA]{code/CustomProvider.java}	
		   
		Provider definition in beans.xml
		\lstinputlisting[language=JAVA]{code/cxf_providers.xml}
	\end{frame}
	
	\begin{frame}{Exception handling in Apache CXF}
		It is possible to prepare custom exception mapper for your given exception type and handle it nicely.
		
		\lstinputlisting[language=JAVA]{code/ExceptionMapper.java} 
		
		Exception Mapper definition in beans.xml
		\lstinputlisting[language=XML]{code/cxf_exception.xml} 
	\end{frame}
	
	\begin{frame}{CXF Advanced Features}
		\begin{itemize}
		  \item multiparts - mapping to InputStream, DataSource or custom Java types
		  \item failover and load distribution - alternate addresses in case of connection failures or heavy load
		  \item complex search queries - mapping query parameters to a bean
		  \item integration with OSGi
		  \item bean with implementation can support JAX-RS and JAX-WS at the same time			
		\end{itemize}
