Re: Injecting proxy services in page.
To be honest, I dont understand exactly what the Problem is. If you work with Spring-Beans, they are normally safe to serialize, as its only the proxy. We´ve done this all the time (even with older wicket versions) without any problems. It looks like you have some Classpath-Issue here. The Service-Class you mentioned, is that an Interface or do you work with the concrete Implementation. I got similar Issues when working with Implementation-Classes and CGLib. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Injecting-proxy-services-in-page-tp4659209p4659580.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: Injecting proxy services in page.
We've heard that there is a fix for this available in Wicket 1.5. However, we are stuck with Wicket 1.4.7 and cannot upgrade, for various reasons. (We're also already using the AnnotationConfigWebApplicationContext referred to in the previous post.) Are there any other workarounds for this problem? Is it OK to make the problem classes implement Serializable just to move past this issue (even if they are injected with the @SpringBean, and are service classes), or should we try other workarounds? -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Injecting-proxy-services-in-page-tp4659209p4659563.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: Injecting proxy services in page.
If you are already using XmlWebApplicationContext (extends AbstractRefreshableWebApplicationContext like AnnotationConfigWebApplicationContext) that is probably not the issue, but you can set the context class in your web.xml like this: servlet ... init-param param-namecontextClass/param-name param-value org.springframework.web.context.support.AnnotationConfigWebApplicationContext /param-value /init-param /servlet -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Injecting-proxy-services-in-page-tp4659209p4659252.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: Injecting proxy services in page.
At the risk of turning this into a Spring discussion on a Wicket forum, how does one control that? I would like to try your suggestion, but am not sure what knob to twist. We just implement ApplicationContextAware, and point to our spring config file in web.xml. I don't set anywhere asking for a particular KIND of appcontext to be used. When it hands it to me, it is XmlWebApplicationContext. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Injecting-proxy-services-in-page-tp4659209p4659245.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
