I have one service class to do the DB operations through the DAO classes , i inject the DAO object using spring. It is working fine.
After that i exposed the same service method as a webservice method using JAX-WS annotation. After that it is not working it saying my dao object not get injected , so i am getting nullpointerexception. the way i am doing is correct or not?
1. Your web service class is NOT managed/under control of Spring IoC container. So there is no DI. That's why NPE.
2. If you want your web service class to be mananged by Spring.
If you use Metro JAX-WS RI, then Metro JAX-WS RI ext has integration with Spring.
Spring will manage your web service class. So DI will be possible/OK.
