configuring Spring

Where in the documentation is this topic discussed?

I am using Tapestry for my presentation so I would have to integrate Spring with it as well as Hibernate and xdoclet.

I would like to use the ApplicationContext and I read in a tutorial (http://www.theserverside.com/article...r/chapter2.pdf) that I needed to add a <listener> to the web.xml file.

So I added:

<listener>
<listener-class> org.springframework.web.context.ContextLoaderListe ner
</listener-class>
</listener>



inside the <webapp> tags and received an error from Tomcat:

You must pay attention where you add the listener in web.xml
The exact sequence of XMl tags in web.xml is provided in the stackTrace:

Code:

---

"(icon?,display-name?,description?,distributable?,context-param*,filter*,filter-mapping*,listener*,servlet*,servlet-mapping*,session-config?,mime-mapping*,welcome-file-list?,error-page*,taglib*,resource-env-ref*,resource-ref*,security-constraint*,login-config?,security-role*,env-entry*,ejb-ref*,ejb-local-ref*)

---

so, you should add <listener> ...</listener> after filter-mapping and before servlet.

HTH

I wasn't aware of that, thank you.

You can have a look at HISPACTA (HIbernate, SPring, ACegi security and TApestry) example application at http://sourceforge.net/projects/hispacta . This may show you solutions to some common problems.
