我正在创建我的第一个项目 Java EE 7,但我遇到了麻烦。感谢任何帮助。
- 雄猫 7.0.34
- JSF 2.2
- Primefaces 3.5
- javaee-api-7.0.jar
当应用程序启动时,Tomcat 日志显示以下消息:
"validateJarFile (C:\...\build\web\WEB-INF\lib\javaee-api-7.0.jar)-jar not loaded. See Servlet 2.3 Spec, section 9.7.2. Offending class: javax/servlet/Servlet .class"
当我单击调用托管 bean 的按钮时,出现错误:
Advertência: /index.xhtml @18,66 value="#{indexMB.user}": Target Unreachable, identifier 'indexMB' resolved to null
javax.el.PropertyNotFoundException: /index.xhtml @18,66 value="#{indexMB.user}": Target Unreachable, identifier 'indexMB' resolved to null
索引MB
@Named("indexMB")
@RequestScoped
public class IndexMB {
private String password;
private String user;
public String loginTest(){
return (this.user.equals("admin") ? "adminPage" : "inOutPage");
}
// getters and setters
}
索引.xhtml
<html ...>
<f:loadBundle basename="i18n" var="bundle" />
<h:head>
<title>#{bundle['index_title']}</title>
</h:head>
<h:body>
#{bundle['index_appname']}
<br />
<h:form id="frmIndex">
<p:panelGrid columns="2">
<p:outputLabel for="user" value="#{bundle['lblUser']}" />
<p:inputText id="user" value="#{indexMB.user}" />
<p:outputLabel for="password" value="#{bundle['lblPassword']}" />
<p:password id="password" value="#{indexMB.password}" />
</p:panelGrid>
<p:commandButton action="#{indexMB.loginTest}" value="#{bundle['btn_login']}" />
</h:form>
</h:body>
