Hi,
I've not had the opportunity to work with Jersey since 0.4 but when I integrated Jersey with Spring using cglib proxied resources, I got Jersey to inject dependencies on the resources as follows:
..
import org.springframework.aop.framework.Advised;
import org.springframework.aop.support.AopUtils;
...
public Object getInstance(ResourceProviderContext context) {
try {
initSpringContext(context);
initBeanName();
Object resource = springContext.getBean(beanName, resourceClass);
if (AopUtils.isAopProxy(resource)) {
Advised aopResource = (Advised) resource;
context.injectDependencies(aopResource.getTargetSource().getTarget());
} else {
context.injectDependencies(resource);
}
return resource;
} catch (Exception ex) {
throw new ContainerException("Unable to create resource", ex);
}
}The above example uses the SPI described here:
http://weblogs.java.net/blog/mhadley/archive/2007/09/integrating_jer.html. This demonstrates how to get at the cglib proxied object using Spring. However, I'm aware that the Jersey SPI has changed quite a bit since I did this.
It would be really nice, if at some point, Jersey had an optional library for users wanting to integrate with Spring.
HTH,
Duncan Eley

Subject: Re: Injectable fields not set on target object for proxied resource (using cglib)
Hmm, this seems like a general problem with proxies. How is this
usually handled, can the jersey component provider get access to the
proxied object somehow or do we need support for injection via bean
setters/getters as an alternative to fields ?
