NoSuchElementException while trying to access any page

[Daniel8]

Hi,

I updated from Spring 3.0.6 to Spring 3.1 RC1 and now cannot access any page. I get the exception below. Nothing has changed in my configuration since I copied the new Spring jars. I have a suspicion that it is related to some handler mappings but do not know were to start looking into this. It seems that something is not backwards compatible in Spring 3.1.
Any hint how to get to the bottom of this is greatly appreciated.

Probably there are dependencies from 3.0.6 that are no longer used in 3.1.

Did you copy the files manually or are you using a build tool like Maven?

Hi Skram

I copied the Spring jars into my web app's lib folder and this broke it.

I solved my own case. One of my colleagues created an annotation based edit controller and in addition mapped it in the someApp-servlet.xml. As we have hundreds of controllers, services, etc. it was quite difficult to find out that this.

<bean name="/policyWordingEdit.htm" class="foo.subfoo.PolicyWordingEditController">

@Controller("policyWordingEditController")
public class PolicyWordingEditController {

It is quite rough that Spring does not throw an easier to understand exception. It was not clear initially that this actually came from a simple setup mistake in someApp-servlet.xml. What is weird is that this mistake was tolerated by Spring 3.0 and threw in 3.1 RC1 a rather not understandable exception.
