jsf - p:commandButton action throws javax.el.PropertyNotFoundException -


the error in:

<!doctype html public "-//w3c//dtd xhtml 1.0 transitional//en"  "http://www.w3.org/tr/xhtml1/dtd/xhtml1-transitional.dtd">  <html xmlns="http://www.w3.org/1999/xhtml"   xmlns:h="http://java.sun.com/jsf/html"   xmlns:f="http://java.sun.com/jsf/core"   xmlns:ui="http://java.sun.com/jsf/facelets"   xmlns:p="http://primefaces.org/ui">  <h:head>     <title>fya web</title> </h:head>    <h:body>       <ui:composition template="/base/base.xhtml">     <ui:param name="title" value="fya web login"/>         <ui:define name="content">             <h:form id="form">                   <p:panel id="panel" header="inicio sesión">                       <p:messages id="panelmsg"/>                        <h:panelgrid columns="3">                           <h:outputlabel for="nomusuario" value="usuario: *" />                           <p:inputtext id="nomusuario" value="#{login.usu.nomusuario}" required="true" label="usuario"/>                          <h:outputlabel for="pwdusuario" value="contraseña: *" />                           <p:password id="pwdusuario" value="#{login.usu.contraseña}" label="contraseña" required="true"/>                       </h:panelgrid>                        <p:commandbutton id="btniniciar" value="iniciar sesión" action="#{login.validar}" update="panelmsg" ajax="true"/>                   </p:panel>               </h:form>         </ui:define>     </ui:composition>         </h:body>

this managed bean.

package pe.edu.cibertec.managed; @managedbean(name="login") public class loginbean {  private usuario usuario=new usuario(); private static loginservice loginservice= new loginserviceimpl();  public usuario getusuario() {     return usuario; }  public void setusuario(usuario usuario) {     this.usuario = usuario; }  public string validar() throws exception {     if(loginservice.validar(usuario))         return "paginas/principal";     else{         facescontext.getcurrentinstance().addmessage(null, new facesmessage("datos incorrectos"));         return null;     } }   }

maybe think im doing wrong, can me please?

that can happen when didn't install primefaces. way <p:xxx> tags treated template text (meaning, not parsed jsf components facelets printed plain vanilla straight html output). el expressions in template text default resolved property value expressions (like in <p>blah #{bean.foo} blah</p>) requires getter method. el expressions represent method expression throw exception because there's no getter found in bean.

to install primefaces, make sure jar file in webapp's /web-inf/lib (if you're using ide eclipse, make sure absolutely not touch build path setting, if ever fiddled there in careless attempt solve it, undo all!), , make sure project rebuilt , server's work folder cleant , deploy in server contain primefaces jar file in right place.

another thing take account, taglib uri http://primefaces.org/ui introduced in primefaces 3.0. if happen have jar of primefaces 2.x or older, can face problem. you'd need either upgrade primefaces @ least 3.0, or fall using 2.x compatible taglib uri http://primefaces.prime.com.tr/ui.

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
