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: Apr 3, 2009 10:54:19 AM org.restlet.engine.StatusFilter getStatus SEVERE: Unhandled exception or error intercepted java.lang.NullPointerException at java.lang.Class.isAssignableFrom(Native Method) at org.restlet.resource.Finder.handle(Finder.java:391) at org.restlet.routing.Filter.doHandle(Filter.java:156) at org.restlet.routing.Filter.handle(Filter.java:201) at org.restlet.routing.Router.handle(Router.java:520) at org.restlet.routing.Filter.doHandle(Filter.java:156) at org.restlet.routing.Filter.handle(Filter.java:201) at org.restlet.routing.Router.handle(Router.java:520) at org.restlet.routing.Filter.doHandle(Filter.java:156) at org.restlet.routing.Filter.handle(Filter.java:201) at org.restlet.routing.Router.handle(Router.java:520) at org.restlet.routing.Filter.doHandle(Filter.java:156) at org.restlet.engine.StatusFilter.doHandle(StatusFilter.java:153) at org.restlet.routing.Filter.handle(Filter.java:201) at org.restlet.routing.Filter.doHandle(Filter.java:156) at org.restlet.routing.Filter.handle(Filter.java:201) at org.restlet.engine.ChainHelper.handle(ChainHelper.java:126) at org.restlet.Component.handle(Component.java:724) at org.restlet.Server.handle(Server.java:355) at org.restlet.engine.ServerHelper.handle(ServerHelper.java:71) at org.restlet.engine.http.HttpServerHelper.handle(HttpServerHelper.java:149) at org.restlet.engine.http.StreamServerHelper$ConnectionHandler.run(StreamServerHelper.java:89) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:441) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:303) at java.util.concurrent.FutureTask.run(FutureTask.java:138) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:619) Apr 3, 2009 10:54:19 AM org.restlet.engine.LogFilter afterHandle INFO: 2009-04-03 10:54:19 127.0.0.1 - - 8182 GET /uniq - 500 365 - 39 http://localhost:8182 Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.8) Gecko/2009032711 Ubuntu/8.10 (intrepid) Firefox/3.0.8 - Here's my applicationContext.xml: <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd";> <bean id="springComponent" class="org.restlet.ext.spring.SpringComponent" init-method="start" destroy-method="stop"> <property name="server"> <bean class="org.restlet.ext.spring.SpringServer"> <constructor-arg value="http" /> <constructor-arg value="8182" /> </bean> </property> <property name="defaultTarget" ref="springRouter" /> </bean> <bean id="springRouter" class="org.restlet.ext.spring.SpringBeanRouter" /> <bean name="/uniq" autowire="byName" id="uniqResource" class="org.example.uniq.rest.UniqResource" scope="prototype"> <property name="nextUniqDao" ref="nextUniqDao" /> </bean> </beans> And UniqResource.java: package org.example.uniq.rest; import java.io.StringReader; import org.example.uniq.dao.NextUniqDao; import org.restlet.data.MediaType; import org.restlet.data.Status; import org.restlet.representation.ReaderRepresentation; import org.restlet.representation.Representation; import org.restlet.representation.Variant; import org.restlet.resource.Resource; import org.restlet.resource.ResourceException; 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) */ 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); } } Clearly I'm missing something basic, but I can't figure it out. Any help would be greatly appreciated! ------------------------------------------------------ http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447&dsMessageId=1535043
