Hi,

I’m very disappointed.
I’ve got a web app under Eclipse (3.2) and Sysdeo Tomcat plug-in.
This web app use the Spring Framework and works fine.

I want to migrate this web app under MyEclipse.
I tried first MyEclipse 5.5.1 and then MyEclipse 6.
In both cases, I get the same beheavior :
Tomcat tells that it can’t find the ContextLoaderListener ; here is the trace :

ERROR [main] – Erreur lors de la configuration de la classe d’écoute de l’application (application listener) org.springframework.web.context.ContextLoaderListener

In fact, when I give Spring capabilities to a project, the libraries uploaded don’t have this package at all (neither Spring 1, nor Spring 2).
So I suppressed MyEclipse Spring capabilities and I copied the spring.jar from my right project under Eclipse/Tomcat Plugin into my WEB-INF/lib under MyEclipse, and put it in the classpath.
Of course, the spring.jar gets the cllass in the right package, but impossible to get a right launch from Tomcat.

How is it possible ; what’s wrong with me ; it seems so basic and I spent so much time on this problem.

Thanks very very very much for a good idea.

Please remove the spring.jar you added to your /lib dir, and then go back to your Java Build Path, to the Libraries tab, and the Spring Core and Spring Web (2.0 if you like) back to your biuld path as seen in the screenshot below.

The classes you need are in the Spring Web library.

Thanks a lot, a lot, a lot.
I had to place somes others lib (like spring-webmvc and some dependancies) but you gave me the right direction ; again thanks.

By the way, when you give capabilities to a project (by the appropriate menu/item), then suppress (by hand) theses capabilities, you could not use anymore the possibility to give back theses capabilities, because the item has became disable in the menu.
The consequence is that it is harder to get the right lib by hand.
Well, couldn’t be possible to edit some parameter file where it is marked that the project has capabilities, and that way find again the initial use of the menu/item ?

I’m glad it helped.

If you mean the libraries (for example, you forget to add all the libraries the first time) you can always get back to them from the Libraries tab, under Add Library then “MyEclipse Libraries”.

Well, couldn’t be possible to edit some parameter file where it is marked that the project has capabilities, and that way find again the initial use of the menu/item ?

It’s possible to manually remove capabilities by removing those natures from the .project file, but it’s not encouraged.
