我正在尝试在外部服务器上运行j2ee项目。项目是在netbeans(6.7.1)中完成的,当我从那里运行它时,一切都很好(我在glassfish v3服务器上运行)。但当我从asadmin脚本运行glassfish并将项目的war文件给他时,它返回异常:
Exception Details: javax.el.PropertyNotFoundException
Target Unreachable, identifier 'loginBean' resolved to null
我在寻找答案,但什么也帮不了我。有什么我想念的,在玻璃鱼配置上网本的地方吗?
关于我发现的最普遍的问题:
loginbean在
faces-config.xml
中声明我已在我的
loginBean
上设置会话范围我在
@ManagedBean()
中没有LoginBean.java
,但我使用的是jsf1.2,而不是2.0我发现可能是因为
myfaces.jar
和sun的jsf,但我首先删除了它,错误仍然出现。我试着把
javaee.jar
放到glassfish/lib

最佳答案
就我而言,原因完全不同。
我复制了一个包含serialversionuid字段的类:
private static final long serialVersionUID = 5443351151396868724L;
所以我有两个不同的类和对象具有相同的serialversionuid,这就是问题的线索。
