Oh. I see. Take a look at com.caucho.security.SecurityContext. You can try: HttpServletRequest request = (HttpServletRequest) com.caucho.security.SecurityContext.getProvider(); You could also try: WebBeansContainer webBeans = WebBeansContainer.getCurrent(); ServletContext webApp = webBeans.getByType(ServletContext.class); As Serge mentioned, you can also create a filter that stores the context in a ThreadLocal. If you do that, make absolutely certain you clear the ThreadLocal at the end of the filter otherwise very bad things will happen.

This is a hack, but what we do is create a ThreadLocal with the current
request object. Something like this:
public abstract class ThreadRequest {
private static ThreadLocal requestHolder = new ThreadLocal();
/**
* Sets the current thread's request.
*/
public static void setRequest(HttpServletRequest request) {
requestHolder.set(request);
}
/**
* Gets the current thread's request.
*/
public static HttpServletRequest getRequest() {
return (HttpServletRequest) requestHolder.get();
}
}
Then you need a filter that sets this and clears it from the thread.
ThreadRequest.setRequest(request);
try {
// Now hand it off to everything else.
chain.doFilter(proxiedRequest, response);
} finally {
ThreadRequest.setRequest(null);
}
This gives you static access to the current request on this thread.
