[jboss-user] [JBoss Seam] - Ajax4JSF mediaOutput tag and Seam

I'm trying to display thumbnails of images I have on the database using a4j:mediaoutput, like this: <a4j:mediaOutput element="img" mimeType="image/jpeg" createContent="#{download.sendThumbnail}" value="#{screenshot.id}" /> The "download" component looks like this: | @Name("download") | @Stateless | public class DownloadBean implements Download { | | @PersistenceContext | private EntityManager em; | | @Override | public void sendImage(OutputStream os, Object screenshotId) throws IOException { | Screenshot ss = em.find(Screenshot.class, screenshotId); | if (ss != null) | os.write(ss.getImageData()); | } | | @Override | public void sendThumbnail(OutputStream os, Object screenshotId) throws IOException { | Screenshot ss = em.find(Screenshot.class, screenshotId); | if (ss != null) | os.write(ss.getThumbnailData()); | } | | } When loading the page, however, I get the following exception in the server console: | 00:49:02,174 ERROR [[default]] Servlet.service() for servlet default threw exception | javax.faces.el.EvaluationException: /entry.xhtml @170,79 createContent="#{download.sendThumbnail}": Target Unreachable, identifier 'download' resolved to null | at com.sun.facelets.el.LegacyMethodBinding.invoke(LegacyMethodBinding.java:73) | at org.ajax4jsf.framework.resource.UserResource.send(UserResource.java:110) | at org.ajax4jsf.framework.resource.ResourceLifecycle.send(ResourceLifecycle.java:86) | at org.ajax4jsf.framework.resource.InternetResourceService.sendResource(InternetResourceService.java:256) | at org.ajax4jsf.framework.resource.InternetResourceService.serviceResource(InternetResourceService.java:240) | at org.ajax4jsf.framework.resource.InternetResourceService.serviceResource(InternetResourceService.java:141) | at org.ajax4jsf.framework.ajax.xmlfilter.BaseFilter.doFilter(BaseFilter.java:261) | at org.jboss.seam.web.Ajax4jsfFilter.doFilter(Ajax4jsfFilter.java:60) | at org.jboss.seam.servlet.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:68) | at org.jboss.seam.web.LoggingFilter.doFilter(LoggingFilter.java:58) | at org.jboss.seam.servlet.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:68) | at org.jboss.seam.debug.hot.HotDeployFilter.doFilter(HotDeployFilter.java:68) | at org.jboss.seam.servlet.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:68) | at org.jboss.seam.servlet.SeamFilter.doFilter(SeamFilter.java:149) | at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) | at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) | at org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) | at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) | at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) | at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:230) | at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:175) | at org.jboss.web.tomcat.security.SecurityAssociationValve.invoke(SecurityAssociationValve.java:179) | at org.jboss.web.tomcat.security.JaccContextValve.invoke(JaccContextValve.java:84) | at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:128) | at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:104) | at org.jboss.web.tomcat.service.jca.CachedConnectionValve.invoke(CachedConnectionValve.java:157) | at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) | at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:241) | at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:844) | at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:580) | at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:447) | at java.lang.Thread.run(Thread.java:619) | So how can it possibly be null? The "download" component is loaded ok, since it shows up in the Seam component list during deploy. What am I doing wrong? Could this be a configuration problem? Using JBoss 4.2.1GA, Seam CVS and Ajax4JSF v1.1.1. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4076051#...
