I am trying out the Spring Extensions of Restlet 1.1RC2 in OSGi, specifically
Equinox 3.4.0, Spring 2.5.5, and Spring-DM 1.1.1. My Spring application context
is using the SpringFinder bean in much the same way the Restlet Spring example
does:
<bean id="v1Router" class="org.restlet.ext.spring.SpringRouter">
<property name="attachments">
<map>
<entry key="/jobs">
<bean class="org.restlet.ext.spring.SpringFinder">
<lookup-method name="createResource" bean="jobsResource"/>
</bean>
</entry>
</map>
</property>
</bean>
When Spring tries to use CGLib for the "lookup-method" it cannot find the CGLib
classes and gets this exception:
Caused by: org.springframework.beans.factory.BeanCreationException: Error
creating bean with name 'org.restlet.ext.spring.SpringFinder#19e215b' defined in

The only solution I've found is to modify the MANIFEST.MF in
org.restlet.ext.spring_2.5.jar and import all the of "net.sf.cglib.*" related
packages. Is this a bug in the Restlet's Spring Extension manifest or might I
have something wrong in my environment?
Thanks for your help,
Adam
