NoClassDefFoundError with DatePicker on app reload
Hello, I've a problem with the DatePicker component. Every time I reload my application (in Eclipse - Run - 'My project' on MyEclipse Tomcat, or with an application undeploy/redeploy on Tomcat), I got the stacktrace below. java.lang.NoClassDefFoundError: org.apache.wicket.extensions.yui.calendar.DatePicker at booby.dbadmin.people.FormPerson.(FormPerson.java:174) at cosimoo.wizardorderprocess.WizardOrderProcess$Address.(WizardOrderProcess.java:90) at cosimoo.wizardorderprocess.WizardOrderProcess.(WizardOrderProcess.java:693) at cosimoo.PagePassOrderOrCustomizeNewProduct$1.onClick(PagePassOrderOrCustomizeNewProduct.java:21) at org.apache.wicket.markup.html.link.Link.onLinkClicked(Link.java:214) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.apache.wicket.RequestListenerInterface.invoke(RequestListenerInterface.java:183) at org.apache.wicket.request.target.component.listener.ListenerInterfaceRequestTarget.processEvents(ListenerInterfaceRequestTarget.java:73) at org.apache.wicket.request.AbstractRequestCycleProcessor.processEvents(AbstractRequestCycleProcessor.java:90) at org.apache.wicket.RequestCycle.processEventsAndRespond(RequestCycle.java:1166) at org.apache.wicket.RequestCycle.step(RequestCycle.java:1241) at org.apache.wicket.RequestCycle.steps(RequestCycle.java:1316) at org.apache.wicket.RequestCycle.request(RequestCycle.java:493) at org.apache.wicket.protocol.http.WicketFilter.doGet(WicketFilter.java:354) at org.apache.wicket.protocol.http.WicketFilter.doFilter(WicketFilter.java:194) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:230) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:175) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:128) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:104) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:261) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:844) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:581) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:447) at java.lang.Thread.run(Unknown Source) However, I'm sure that class is in my path...

Re: NoClassDefFoundError with DatePicker on app reload
iirc, YuiLib calls Application.get() to check whether the app is in deployment/development mode. gerolf On Wed, Feb 20, 2008 at 9:26 PM, Martijn Dashorst [EMAIL PROTECTED] wrote: Erhm, are they trying to do something like Application.get()?
