Re: wicket 1.6 snapshot - cdi - inject - NullPointerException
At the startup I can see WELD-000106 Bean: Managed Bean [class bookstoremodel.cdi.BigBenClock] with qualifiers [@Any @Default] BigBenClock reacts as it was not managed.

looks like a cdi problem since the NPE is inside BigBenClock which is created and injected by cdi... strange. -igor On Sat, Jul 28, 2012 at 2:41 PM, Francois Meillet wrote: > Here it is : > > org.apache.wicket.WicketRuntimeException: Can't instantiate page using > constructor 'public > bookstoreweb.test.BookPage(org.apache.wicket.request.mapper.parameter.PageParameters)' > and argument 'c=[color] > at > org.apache.wicket.session.DefaultPageFactory.newPage(DefaultPageFactory.java:193) > ~[wicket-core-6.0-SNAPSHOT.jar:6.0-SNAPSHOT] > at > org.apache.wicket.session.DefaultPageFactory.newPage(DefaultPageFactory.java:98) > ~[wicket-core-6.0-SNAPSHOT.jar:6.0-SNAPSHOT] > at > org.apache.wicket.session.DefaultPageFactory.newPage(DefaultPageFactory.java:44) > ~[wicket-core-6.0-SNAPSHOT.jar:6.0-SNAPSHOT] > at > org.apache.wicket.DefaultMapperContext.newPageInstance(DefaultMapperContext.java:137) > ~[wicket-core-6.0-SNAPSHOT.jar:6.0-SNAPSHOT] > at > org.apache.wicket.core.request.handler.PageProvider.resolvePageInstance(PageProvider.java:278) > ~[wicket-core-6.0-SNAPSHOT.jar:6.0-SNAPSHOT] > at > org.apache.wicket.core.request.handler.PageProvider.getPageInstance(PageProvider.java:166) > ~[wicket-core-6.0-SNAPSHOT.jar:6.0-SNAPSHOT] > at > org.apache.wicket.request.handler.render.PageRenderer.getPage(PageRenderer.java:78) > ~[wicket-core-6.0-SNAPSHOT.jar:6.0-SNAPSHOT] > at > org.apache.wicket.request.handler.render.WebPageRenderer.renderPage(WebPageRenderer.java:93) > ~[wicket-core-6.0-SNAPSHOT.jar:6.0-SNAPSHOT] > at > org.apache.wicket.request.handler.render.WebPageRenderer.respond(WebPageRenderer.java:237) > ~[wicket-core-6.0-SNAPSHOT.jar:6.0-SNAPSHOT] > at > org.apache.wicket.core.request.handler.RenderPageRequestHandler.respond(RenderPageRequestHandler.java:165) > ~[wicket-core-6.0-SNAPSHOT.jar:6.0-SNAPSHOT] > at > org.apache.wicket.request.cycle.RequestCycle$HandlerExecutor.respond(RequestCycle.java:814) > ~[wicket-core-6.0-SNAPSHOT.jar:6.0-SNAPSHOT] > at > org.apache.wicket.request.RequestHandlerStack.execute(RequestHandlerStack.java:64) > ~[wicket-request-6.0-SNAPSHOT.jar:6.0-SNAPSHOT] > at > org.apache.wicket.request.cycle.RequestCycle.execute(RequestCycle.java:253) > [wicket-core-6.0-SNAPSHOT.jar:6.0-SNAPSHOT] > at > org.apache.wicket.request.cycle.RequestCycle.processRequest(RequestCycle.java:210) > [wicket-core-6.0-SNAPSHOT.jar:6.0-SNAPSHOT] > at > org.apache.wicket.request.cycle.RequestCycle.processRequestAndDetach(RequestCycle.java:281) > [wicket-core-6.0-SNAPSHOT.jar:6.0-SNAPSHOT] > at > org.apache.wicket.protocol.http.WicketFilter.processRequest(WicketFilter.java:188) > [wicket-core-6.0-SNAPSHOT.jar:6.0-SNAPSHOT] > at > org.apache.wicket.protocol.http.WicketFilter.doFilter(WicketFilter.java:245) > [wicket-core-6.0-SNAPSHOT.jar:6.0-SNAPSHOT] > at > org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:243) > [catalina.jar:7.0.25] > at > org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:210) > [catalina.jar:7.0.25] > at > org.apache.catalina.filters.ExpiresFilter.doFilter(ExpiresFilter.java:1179) > [catalina.jar:7.0.25] > at > org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:243) > [catalina.jar:7.0.25] > at > org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:210) > [catalina.jar:7.0.25] > at > org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:243) > [catalina.jar:7.0.25] > at > org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:210) > [catalina.jar:7.0.25] > at > org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:224) > [catalina.jar:7.0.25] > at > org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:169) > [catalina.jar:7.0.25] > at > org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:472) > [catalina.jar:7.0.25] > at > org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:168) > [catalina.jar:7.0.25] > at > org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:98) > [catalina.jar:7.0.25] > at > org.apache.catalina.valves.AccessLogValve.invoke(AccessLogValve.java:927) > [catalina.jar:7.0.25] > at > org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:118) > [catalina.jar:7.0.25] > at > org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:407) > [catalina.jar:7.0.25] > at > org.apache.coyote.http11.AbstractHttp11Processor.process(AbstractHttp11Processor.java:987) > [tomcat-coyote.jar:7.0.

wicket 1.6 snapshot - cdi - inject - NullPointerException
Hi All,
The problem is : I got a NullPointerException after using @Inject
environment : wicket 1.6 snapshot - cdi (weld) - inject - NullPointerException
- tomcat 7 / jboss AS 7
module 1 : bookstoreservice (with a beans.xml file)
module 2 : bookstoreweb (with a beans.xml file)
in the bookstoreservice module I have these 2 classes:
@ApplicationScoped
public class Clock {
public DateTime getTime() {
return new DateTime().now();
}
}
@ApplicationScoped
public class BigBenClock {
@Inject
Clock clock;
public BigBenClock() {
}
public DateTime getBigBenTime() {
return clock.getTime().plusHours(2);
}
}
First use : All works fine
In a webpage, I have
@Inject
Clock clock;
@Inject
BigBenClock bigBenClock;
add(new Label("time", new PropertyModel(this, "clock.time")));
add(new Label("bigBenTime", new PropertyModel(this,
"bigBenClock.bigBenTime")));
All works fine, thanks to Igor's example
https://www.42lines.net/2011/11/15/integrating-cdi-into-wicket/
Second use : NullPointerException
If I use the injection in the bookstoreservice module with no injection in the
webpage like this
@Inject
Clock clock;
add(new Label("time", new PropertyModel(this, "clock.time")));
BigBenClock bigBenClock = new BigBenClock();
DateTime bigBenTime = bigBenClock.getBigBenTime();
I get a NullPointerException. The BigBenClock's clok is null.
Same result in Tomcat 7 and Jboss AS7.
This is how I start the Wicket application
getComponentInstantiationListeners().add(new JavaEEComponentInjector(this, new
ModuleJndiNamingStrategy()));
BeanManager beanManager = (BeanManager)getServletContext().getAttribute(
Listener.BEAN_MANAGER_ATTRIBUTE_NAME);
new
CdiConfiguration(beanManager).setPropagation(ConversationPropagation.NONE).configure(this);
Any advice ?
Thanks
François
