Components.xml Class loader not found

[jugovi]

I have created a Patato project who has an entity class PrettyPatato. Eclipse creates 2 more classes deriving EntityHome and EntityQuery. Their names are PrettyPatatoHome and PrettyPatatoList respectively.

Then in components.xml I define a component named componentPotato.
Here is my component.xml code

<component class="org.domain.patato.session.PrettyPatatoList" name="componentPotato"/>

When I start the JBoss Server through Eclipse it gives me this error

Exception sending context initialized event to listener instance of class org.jboss.seam.servlet.SeamListener

java.lang.RuntimeException: error while reading /WEB-INF/components.xml

     at org.jboss.seam.init.Initialization.initComponentsFromXmlDocument(Initialization.java:154)

     at org.jboss.mx.loading.LoadMgr3.beginLoadTask(LoadMgr3.java:306)

......

No other modifications have been made to the project.

Here is my configuration
Java 1.5,
Seam 2.0.1GA,
JBoss 4.2.2GA

Any help will be highly appreciated.

Are you using an ear project that contains a war module or just a standalone war project?

[jugovi]

Thanks Keith for reading my post.

I use a standalone WAR project.

I juste made a test which was to move PrettyPatatoList to the entity package and the components.xml file got read without any problems.

I know Eclipse uses a different deployment method for the entity and the session packages. How can I fix this diference without breaking the way Eclipse works.

I will keep working on it but any comment will be highly apreciated.

Sounds like you're using the Eclipse JBoss Tools, and unfortunately, I'm not that familiar with them.

You might try reading ClassLoadingConfiguration.

Its possible it could provide some clues, especially if you look at the artifacts that are deployed to your jboss server.

I'd assume this is a hotdeploy class in WEB-INF/dev.  Hot deployed classes cannot be referenced in components.xml.

Thank you for comfirming what i taught.
Fot those wondering how i bypassed this problem,I simply created another folder and within the same packageName as in the hot-deploy folder.

So when I have finished working on my class I simply drag and drop the file in the non hot-deploy folder.
