anil halil created SEAMREST-58: ---------------------------------- Summary: NullPointerException when templating enabled Key: SEAMREST-58 URL: https://issues.jboss.org/browse/SEAMREST-58 Project: Seam REST Issue Type: Bug Components: Templating Affects Versions: 3.1.0.Final Reporter: anil halil I enabled solder catch with this annotations @ExceptionMapping.List({ @ExceptionMapping(exceptionType = NotFoundException.class, status = 404, message = "Requested resource does not exist."), @ExceptionMapping(exceptionType = IllegalArgumentException.class, status = 400, message = "Illegal argument value.") }) which should produce 404 for unknown/not mapped urls. But when i enter an unknown url it produces java.lang.NullPointerException at org.jboss.seam.rest.templating.TemplatingMessageBodyWriter.findAnnotation(TemplatingMessageBodyWriter.java:112) at org.jboss.seam.rest.templating.TemplatingMessageBodyWriter.isWriteable(TemplatingMessageBodyWriter.java:97) at org.jboss.seam.rest.templating.TemplatingMessageBodyWriter$Proxy$_$$_WeldClientProxy.isWriteable(TemplatingMessageBodyWriter$Proxy$_$$_WeldClientProxy.java) at org.jboss.resteasy.spi.ResteasyProviderFactory.getMessageBodyWriter(ResteasyProviderFactory.java:1033) at org.jboss.resteasy.core.SynchronousDispatcher.resolveContentTypeByAccept(SynchronousDispatcher.java:615) at org.jboss.resteasy.core.SynchronousDispatcher.writeJaxrsResponse(SynchronousDispatcher.java:591) at org.jboss.resteasy.core.SynchronousDispatcher.writeFailure(SynchronousDispatcher.java:433) at org.jboss.resteasy.core.SynchronousDispatcher.executeExceptionMapper(SynchronousDispatcher.java:335) at org.jboss.resteasy.core.SynchronousDispatcher.handleException(SynchronousDispatcher.java:235) at org.jboss.resteasy.core.SynchronousDispatcher.invoke(SynchronousDispatcher.java:129) at org.jboss.resteasy.plugins.server.servlet.ServletContainerDispatcher.service(ServletContainerDispatcher.java:208) at org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher.service(HttpServletDispatcher.java:55) at org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher.service(HttpServletDispatcher.java:50) at javax.servlet.http.HttpServlet.service(HttpServlet.java:848) at org.eclipse.jetty.servlet.ServletHolder.handle(ServletHolder.java:594) at org.eclipse.jetty.servlet.ServletHandler$CachedChain.doFilter(ServletHandler.java:1365) at org.jboss.solder.servlet.event.ServletEventBridgeFilter.doFilter(ServletEventBridgeFilter.java:74) at org.eclipse.jetty.servlet.ServletHandler$CachedChain.doFilter(ServletHandler.java:1336) at org.jboss.solder.servlet.exception.CatchExceptionFilter.doFilter(CatchExceptionFilter.java:65) at org.eclipse.jetty.servlet.ServletHandler$CachedChain.doFilter(ServletHandler.java:1336) at org.eclipse.jetty.servlet.ServletHandler.doHandle(ServletHandler.java:483) at org.eclipse.jetty.server.handler.ScopedHandler.handle(ScopedHandler.java:119) at org.eclipse.jetty.security.SecurityHandler.handle(SecurityHandler.java:524) at org.eclipse.jetty.server.session.SessionHandler.doHandle(SessionHandler.java:233) at org.eclipse.jetty.server.handler.ContextHandler.doHandle(ContextHandler.java:1065) at org.eclipse.jetty.servlet.ServletHandler.doScope(ServletHandler.java:412) at org.eclipse.jetty.server.session.SessionHandler.doScope(SessionHandler.java:192) at org.eclipse.jetty.server.handler.ContextHandler.doScope(ContextHandler.java:999) at org.eclipse.jetty.server.handler.ScopedHandler.handle(ScopedHandler.java:117) at org.eclipse.jetty.server.handler.ContextHandlerCollection.handle(ContextHandlerCollection.java:250) at org.eclipse.jetty.server.handler.HandlerCollection.handle(HandlerCollection.java:149) at org.eclipse.jetty.server.handler.HandlerWrapper.handle(HandlerWrapper.java:111) at org.eclipse.jetty.server.Server.handle(Server.java:351) at org.eclipse.jetty.server.AbstractHttpConnection.handleRequest(AbstractHttpConnection.java:454) at org.eclipse.jetty.server.AbstractHttpConnection.headerComplete(AbstractHttpConnection.java:890) at org.eclipse.jetty.server.AbstractHttpConnection$RequestHandler.headerComplete(AbstractHttpConnection.java:944) at org.eclipse.jetty.http.HttpParser.parseNext(HttpParser.java:634) at org.eclipse.jetty.http.HttpParser.parseAvailable(HttpParser.java:230) at org.eclipse.jetty.server.AsyncHttpConnection.handle(AsyncHttpConnection.java:76) at org.eclipse.jetty.io.nio.SelectChannelEndPoint.handle(SelectChannelEndPoint.java:609) at org.eclipse.jetty.io.nio.SelectChannelEndPoint$1.run(SelectChannelEndPoint.java:45) at org.eclipse.jetty.util.thread.QueuedThreadPool.runJob(QueuedThreadPool.java:599) at org.eclipse.jetty.util.thread.QueuedThreadPool$3.run(QueuedThreadPool.java:534) at java.lang.Thread.run(Thread.java:722) The problem arise from protected MediaType resolveContentTypeByAccept(List<MediaType> accepts, Object entity) { if (accepts == null || accepts.size() == 0 || entity == null) { return MediaType.WILDCARD_TYPE; } Class clazz = entity.getClass(); Type type = null; if (entity instanceof GenericEntity) { GenericEntity gen = (GenericEntity) entity; clazz = gen.getRawType(); type = gen.getType(); } for (MediaType accept : accepts) { if (providerFactory.getMessageBodyWriter(clazz, type, null, accept) != null) { return accept; } } return MediaType.WILDCARD_TYPE; } as you see getMessageBodyWriter has null as annotations parameter and TemplatingMessageBodyWriter findAnnotation function has this line for (Annotation a : annotations) which rises NullPointerException -- This message is automatically generated by JIRA.
