WAB context not finding local classes [message #739911]

I'm running Virgo Jetty 3.0.1; my setup looks like this:

src/
    com/foo/bar/
                Baz.java
WebContent/
    META-INF/
        spring/
            baz-context.xml
        MANIFEST.MF
    WEB-INF
        web.xml

baz-context.xml contains (... is the xmlns stuff):

<beans ...>
    <bean id="baz" class="com.foo.bar.Baz" />
</beans>

When I start this bundle I get an error:

Caused by: java.lang.ClassNotFoundException: com.foo.bar.Baz

My web.xml contains:

	<context-param>
		<param-name>contextClass</param-name>
		<param-value>org.eclipse.virgo.web.dm.ServerOsgiBundleXmlWebApplicationContext</param-value>
	</context-param>
	
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>

Clearly Baz is a class. Strangely, if I move my spring config to the WEB-INF directory and set it up to be loaded by the servlet loader (using the web.xml stuff), the class is found and things come up just fine -- which leads me to believe the MANIFEST is correct and the actual class is getting included.

Why can't I initialize this class in the spring/ folder?

Supposing I can eventually initialize that bean with a config in the spring/ folder, can beans in servlet specific contexts reference items defined in those configs?

Hi,

You can either put all your spring context information in the applicationContext.xml file under WEB-INF and no config will be required in the web.xml or keep it in META-INF/spring and specify that as the location with 'contextConfigLocation' context-param.

Yes, servlet specific contexts will have full access to beans in your spring/osgi context, it will be one of its parent contexts due to the config you have put in web.xml as shown in your post.

As a side note, all the Manifest should need is the bundle classpath being set to include WEB-INF/classes where Baz.class should be compiled to.

That would bring spring-dm extender into the picture. You want to keep spring context files out of META-INF/spring for web-apps and let org.eclipse.virgo.web.dm.ServerOsgiBundleXmlWebApplicationContext deploy them.
