Load application context for web services

[tasdemir]

I defined a class for loading context to use from web services. I doubt whether it is correct or not. Within web service I call it like: SpringUtil.getBean("xxxx").methodXXX();

public class SpringUtil {

static ApplicationContext springContext = null;

public static ApplicationContext getContext() {
if (springContext == null)
springContext = new ClassPathXmlApplicationContext("beans.xml");

return springContext;
}

public static Object getBean(String beanName) {
return getContext().getBean(beanName);
}
}

Why?! A Web Service normally runs in a Container from there you can load a context with the ContextLoaderListener and setup everything from there. Inject your beans instead of looking them up etc.

If you really fancy the lookup then use the WebApplicationContextUtils to retrieve a reference to the context loaded by the ContextLoaderListener.

You are right, but I'm only curious if I use something like this, also not only for web services, is there anything wrong for thread-safety or some other Spring philosophy.

It depends if it all belongs to one application I would want to make sure that there is only one application context. However with this you might run into the fact that you have multiple instances (a singelton per classloader).

Thanks for your replies

I defined the ContextLoaderListener in web.xml but how will i get context in a java class (web service).
