Injecting in Interceptors
Hi there, I am developing a Authorization interceptor and need to perform a JNDI lookup to get some Stateless EJBs from JBoss. My problem is that this interceptor init() method gets no parameters. I need to get at least the ServletContext of the web application to specify the main JNDI lookup name. (EJBs might be deployed in different JNDIs dirs depending on which application I deploy them). Anybody has an idea on how can I get info about ServletContext in the init() method of an interceptor? I'd like to lookup EJBs there and not lookup them for every request (I know I can get the info I need from ActionInvocation object that every intercept() gets) I'm using Struts 2.1 Thanks for any ideas, Ignacio -- View this message in context: http://www.nabble.com/Injecting-in-Interceptors-tp21570523p21570523.html Sent from the Struts - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org

org.apache.struts2.ServletActionContext.getServletContext() is what you want. musachy On Tue, Jan 20, 2009 at 3:03 PM, Ignacio de Córdoba icord...@skios.es wrote: Hi there, I am developing a Authorization interceptor and need to perform a JNDI lookup to get some Stateless EJBs from JBoss.

Re: Injecting in Interceptors
Hi Musachy and thanks for your reply but that static invocation in that class is not working if called from an interceptor or, at least, from the init() method of the interceptor. Probably this is due to the way it gets the ServletContext. Probably it first gets the request or the session, and uses current thread for that. As in the init() method there is no Action (remember Interceptors are not binded to an action or request, but instanciated only once at the web application deployment) there is no request/response/session, and so I returns null. No ServletContext. :-( Any other ideas? :-) Thanks, Ignacio Musachy Barroso wrote: org.apache.struts2.ServletActionContext.getServletContext() is what you want. musachy On Tue, Jan 20, 2009 at 3:03 PM, Ignacio de Córdoba icord...@skios.es wrote: Hi there, I am developing a Authorization interceptor and need to perform a JNDI lookup to get some Stateless EJBs from JBoss.

agr, that's true, it won't be available on the init method.

You don't need to get JNDI resources on every request--use the lazy initialization pattern and only get it the first time. Since interceptors aren't re-instantiated this should work fine.

Re: Injecting in Interceptors
Thanks for your reply Dave, I'll have to solve it that way... but I wanted to use the init() method and so avoid the if() checking for the EJBS existance... Without any info about the environment I don't really get how that method is useful for anything.

Re: Injecting in Interceptors
Hi, I saw that plugin but it solves the application name subdir to be supplied in the JNDI lookup with a parameter in the Annotation, which makes it code dependant. I need to get that data from the ServletContext (application name) or at least a webapp init parameter. As I see it, the lazy load aproach seems the best for the moment.
