jsf - javax.el.PropertyNotFoundException:在类型 ma.controle.gestion.modele.Activite 上找不到属性“机构”
我正在使用 JSF 2.2.8 和休眠,我在下面的模型中有这个枚举,当我运行我的项目时出现这个错误
这是包含枚举字段的活动表的结构。
这是枚举
并且与下面的 Activite 模型有关系
这是我的我的后盾
这是我的 XHTML 我有这个 selectOneMenu
jsf - 它提供 PropertyNotFoundException Primefaces pieModel 和 JSFBeans
它提供了 PropertyNotfoundexception,但我不明白为什么,因为我有 getter 和 setter
javax.el.PropertyNotFoundException: /pages/protected/search2.xhtml @23,67 listener="#{fewosByRegionBean.getFewosByRegion().pieModel}": Target Unreachable, 'null' returned null
jsf - javax.el.PropertyNotFoundException:在类型 tn.ccs.evoice.entity.TicketSubject 上找不到属性“displayOrder”
1/我最近在我的 postgres 数据库中添加了一个列 (display_order):
2/我已经更新了它的相关实体:
3/ 我想使用以下代码在 jsf 页面中使用新列:
==> 我收到了这个错误:
请问我该怎么办?
jsf - 目标不可达返回空 JSF
我正在为我写一个小项目。它应该能够将一些属性保存到数据库中。这是我的 xhtml 片段:
因此,我的 Java 代码:
如果我正在执行此操作,我的 JBoss 会抛出带有 Text: Target Unreachable 'store' 的 PropertyNotFoundException,返回 null。我认为它应该工作,有人可以帮助我吗?
jsf - 具有默认方法 JSF 的接口中的 Getter
我有一个具有以下默认方法的接口:
我也有一个实现这个接口的控制器,但它不会覆盖该方法。
我正在尝试从我的 xhtml 访问此方法,如下所示:
但是,当我打开屏幕时,会出现以下错误:
如果我从控制器的实例访问此方法,它会返回正确的值,但是当我尝试从我的 xhtml 作为“属性”访问它时,会出现此错误。
有没有办法从我的控制器的引用中访问这个接口属性而不必实现该方法?
jsf - Changing faces-config.xml from 2.2 to 2.3 causes javax.el.PropertyNotFoundException: Target Unreachable, identifier 'bean' resolved to null
Have the following code snippets:
Bean:
faces-config.xml
group.xhtml
In result getting the exception:
Got it after changing faces-config.xml from ver 2.2 to ver 2.3 syntax.
Meaning, with faces-config.xml with the following content everything works fine:
JSF 2.3.2 deployed on the Payara 4.1.2.172 (Full) server, and also added to pom.xml with "provided" scope.
I have checked all solutions that I was able to find during several hours, including different version of beans.xml:
- initially beans.xml was not present in the project - issue persist;
- added empty beans.xml - issue persist;
- added beans.xml with two different options of bean-discovery-mode - "all" and "annotated" - issue persist;
Content of \WEB-INF\beans.xml:
Tested on local instances of Payara 4.1.2.172, GlassFish 5 (java ver 1.8.0_144), and remote instance of Payara 4.1.2.172 (java ver 1.8.0_131).
Thanks!
Note: Example projects like this one https://github.com/AnghelLeonard/JSF-2.3/tree/master/JSF23InjectInConverterValidator give the same error.
jsf - 目标不可达,标识符“测试”解析为空
索引.xhtml
测试.java
错误:
javax.servlet.ServletException: /index.xhtml @41,61 value="#{Test.adSoyad}": 目标不可达,标识符“测试”解析为空
javax.el.PropertyNotFoundException: /index.xhtml @41,61 value="#{Test.adSoyad}": 目标无法到达,标识符“测试”解析为空
javax.el.PropertyNotFoundException:目标不可达,标识符“测试”解析为空
jsf - Mojarra 2.3 中的 CDI 托管 bean 抛出 PropertyNotFoundException,目标无法访问,标识符“localeBean”解析为 null
我在 JSF 2.3 和 CDI 应用程序中发现 bean 有问题。我正在使用 Glassfish 5.0、Java 8 (1.8.0_151)。我的文件:
面孔-config.xml
LocaleBean:
向此 bean 提交表单后 Glassfish 日志中的消息:
javax.el.PropertyNotFoundException: /home.xhtml @15,81 value="#{localeBean.language}": 目标不可达,标识符'localeBean'解析为空
只有当我使用下面列出的导入而不是 javax.enterprise.context 包中的 @Named 和 @SessionScoped 时,表单提交才有效。
但是两者在 JSF 2.3 中都被弃用了。
有什么想法吗?谢谢!
jsf - Target Unreachable, identifier 'userBean' resolved to null
- There are two ways to configure managed beans, one is Using the "faces-config.xml" file, another is using "annotations".
- So in this demo, I want to configure beans using annotations in MyEclipse, but it didn't work.
- Here is the code:
1.UserBean.java
2.Login.xhtml the page users enter the id and password
3.Welcome.xhtml when user click the submit button, the page comes
4.faces-config.xml faces-config.xml
As you can see, I didn't configure the managed bean in the "faces-config.xml" file, I just use "@Named("userBean")" and "@RequestScoped" in my "UserBean.java" file to configure the bean.
1.I open the login.xhtml on the website
2.When I click the button to submit the data, it comes up this page:
I started to learn JSF these days, there are many confused things I need to figure out, thanks a lot if you can give me some notes or guidance on this question ^_^
(Ps.This is the first question I ask on stackoverflow, so I couldn't upload pictures directly, if you cannot see the pictures by hperlinks, please let me know.Thanks!)
jsp - org.apache.jasper.el.JspPropertyNotFoundException
我在代码中找不到属性异常时遇到了困难。我遵循了公共 getter 和 setter 的正确命名约定,但仍然收到异常,我不知道为什么。我一直在寻找解决方案,但没有发布高低。我究竟做错了什么?难道是我正在访问一个列表?
