org.springframework.osgi.service.importer.support. OsgiServiceCollectionProxyFactoryBean not found

[Beta User]

I trying to use the <osgi:list> in eclipse and I am getting the following error:

Class 'org.springframework.osgi.service.importer.support .OsgiServiceCollectionProxyFactoryBean' not found

I get this error after inserting the list element in my spring configuration file:

<osgi:list id="someId">
</osgi:list>

Context sensitive help shows that "<osgi:list> is available; however, when I type the above in I get the error mentioned. Is anyone successfully using <osgi:lists> from eclipse?

Hi

I've got similar problem using <osgi:set />. So far I found I need to add this to MANIFEST.MF:

Import-Bundle: org.springframework.osgi.core;version="[1.1.1.A,1.1.1.A]"

However, the set still does not contain references to services I'm about. Will post more details later on.

Ok, so I found out that a set of osgi services is actually resolved, but the autowiring of such set is failing. Here's what I've got:

bundle A - module-context.xml:
<bean id="barService" class="com.myapp.service.bar.BarService" />

bundle A - osgi-context.xml:
<osgi:service id="osgiBarService" interface="com.myapp.service.AppService" ref="barService" />

bundle B - module-context.xml
<bean id="serviceManager" class="com.myapp.manager.AppServiceManager" />

bundle B - osgi-context.xml
<osgi:set id="services" interface="com.myapp.service.AppService" />

bundle B - AppServiceManager.java

public class AppServiceManager {
@Autowired
protected Set<AppService> services;
}

However, if I inject the dependency, it works:

<bean id="serviceManager" class="com.myapp.manager.AppServiceManager">
<property name="services" ref="services" />
</bean>


Any ideas?

Have you enabled autowiring/component scanning (http://static.springframework.org/spring/docs/2.5.x/reference/beans.html#beans-annotation-config)?

Cheers,

Yes, I did. The error occurs when doing the actual autowiring. Here's the root cause of the exception I'm getting:

Can you please raise an issue on Spring-DM tracker? I'll take a closer look at it (the error message about the bean type is interesting)...

Thanks,

Hi,
There is a misunderstanding on how Autowired works with collections and arrays. See here:
http://static.springframework.org/spring/docs/2.5.x/reference/beans.html#beans-autowired-annotation
Basically when injecting an array or collection of type X, Spring will look for all beans of type X and it will inject those rather then injection a bean that is an array or collection.

[Beta User]

Right, I understand. So it is a limitation of Spring autowiring feature which works for simple beans only, not for maps, sets, etc. It means that even beans defined using <util:map /> or <util:set /> cannot be autowired.

[Beta User]

Actually, there's already an issue raised in Spring Issue Tracker: http://jira.springframework.org/browse/SPR-5038
