RE: Spring + Restlet 1.2-SNAPSHOT, NullPointerException
Thanks to Kevin and Jerome's help, I was able to get a working Spring
configuration. It still uses the deprecated Resource class, but it works for
now and that's good
enough for my needs. In case anyone is following this thread, here are the
details:
applicationContext.xml:
http://www.springframework.org/schema/beans";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xmlns:aop="http://www.springframework.org/schema/aop";
xmlns:tx="http://www.springframework.org/schema/tx";
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-2.5.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop-2.5.xsd";>
UniqResource.java:
public class UniqResource extends Resource {
private NextUniqDao nextUniqDao;
public final void setNextUniqDao(NextUniqDao nextUniqDao) {
this.nextUniqDao = nextUniqDao;
}
/** @see
org.restlet.resource.Resource#represent(org.restlet.representation.Variant) */
@Override
public Representation represent(Variant variant) throws
ResourceException {
Long next = this.nextUniqDao.pop();
this.getResponse().setStatus(Status.SUCCESS_OK);
return new ReaderRepresentation(new
StringReader(next.toString()), MediaType.TEXT_PLAIN);
}
/** @see org.restlet.resource.Resource#init(org.restlet.Context,
org.restlet.data.Request, org.restlet.data.Response) */
@Override
public void init(Context context, Request request, Response response) {
super.init(context, request, response);
getVariants().add(new Variant(MediaType.TEXT_PLAIN));
}
}
And finally, UniqSpringBeanRouter.java:
public class UniqSpringBeanRouter extends SpringBeanRouter {
/** @see
org.restlet.ext.spring.SpringBeanRouter#createFinder(org.springframework.beans.factory.BeanFactory,
java.lang.String) */
protected Finder createFinder(BeanFactory beanFactory, String beanName) {
SpringBeanFinder springBeanFinder = new SpringBeanFinder(beanFactory,
beanName);
springBeanFinder.setTargetClass(UniqResource.class);
return springBeanFinder;
}
}

RE: Spring + Restlet 1.2-SNAPSHOT, NullPointerException
Thanks for the resources, Jerome. I'll take a look and see what I can learn from them! -- http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447&dsMessageId=151
Spring + Restlet 1.2-SNAPSHOT, NullPointerException
I've been having trouble getting Spring to play nice with Restlet (I'm
experienced with Spring, a newbie with Restlet, so please bear with me!).
Using Spring 2.5.6 and Restlet 1.2-SNAPSHOT.
I want to define a resource called "uniq" and map /uniq to my UniqResource
bean (extends Resource). Simple, yeah? When I browse to
http://localhost:8182/uniq, I get the following stack trace:

}
/** @see

Long next = this.nextUniqDao.pop();
this.getResponse().setStatus(Status.SUCCESS_OK);
return new ReaderRepresentation(new StringReader(next.toString()),
MediaType.TEXT_PLAIN);
}
}
Clearly I'm missing something basic, but I can't figure it out. Any help
would be greatly appreciated!
