用eclipse+myeclipse+tomcat开发JSF时遇到的问题

我的配置:eclipse: eclipse-SDK-3.2.1-win32
myeclipse: MyEclipseEnterpriseWorkbenchInstaller_5.1.0GA_E3.2.1
tomcat: apache-tomcat-6.0.2我有一条语句:
<h:inputText required="false" value="#{user.name}"/>
运行时报错:
According to TLD or attribute directive in tag file, attribute value does not accept any expressions
我在另一个环境试过，没错（myeclipse5.0，tomcat版本记不清了）
请高手帮忙看看，别嫌分少哈，没分了。内容:
User.java:
package mypro;public class User {
private String name;
public void setName(String name)
{
this.name=name;
}
public String getName()
{
return this.name;
}
}
