Question

我有一个Netbeans 7.4 / Jdk7 / Tomcat7的项目。

Project在前端使用Spring框架，在后端使用soap WCF服务。我声明，服务中的一种方法存在问题。我可以在Spring中获得此方法而不会出现任何编译错误，但是当我尝试运行该项目时会抛出异常：

org.apache.jasper.JasperException：无法为JSP编译类：
    在jsp文件中的行：30处发生错误：/ WEB-INF/jsp/include/page_header.jsp
   对于UserInfo类型
，方法isIsPosUser（）未定义

我的UserInfo类：

[Serializable, XmlRoot("user_info")]
[DataContract(Name = "user_info", Namespace = "urn:...")]
public class UserInfo
{
    private String _FullName;
    private String _EMail;
    private bool _IsPosUser;

    public UserInfo(string pFullName, 
                    string pEmail)
    {
        FullName = pFullName;
        EMail = pEmail;
    }

    public UserInfo()
    {
        //dummy
    }

    [XmlElement(ElementName = "full_name")]
    [DataMember(Name = "full_name")]
    public string FullName
    {
        get { return _FullName; }
        set { _FullName = value; }
    }

    [XmlElement(ElementName = "e_mail")]
    [DataMember(Name = "e_mail")]
    public string EMail
    {
        get { return _EMail; }
        set { _EMail = value; }
    }

    [XmlElement(ElementName = "IsPosUser")]
    [DataMember(Name = "IsPosUser")]
    public bool IsPosUser
    {
        get { return _IsPosUser; }
        set { _IsPosUser = value; }
    }

    public override string ToString()
    {
        return string.Format("FullName: {0}, EMail: {1}, IsPosUser: {2}", FullName, EMail, IsPosUser);
    }
}

在spring app中生成导入的wsdl的源代码：

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "UserInfo", propOrder = {
"fullName",
"eMail",
"isPosUser"
})
public class UserInfo {

@XmlElement(name = "full_name")
protected String fullName;
@XmlElement(name = "e_mail")
protected String eMail;
@XmlElement(name = "IsPosUser")
protected boolean isPosUser;


/**
 * Gets the value of the fullName property.
 * 
 * @return
 *     possible object is
 *     {@link String }
 *     
 */
public String getFullName() {
    return fullName;
}

/**
 * Sets the value of the fullName property.
 * 
 * @param value
 *     allowed object is
 *     {@link String }
 *     
 */
public void setFullName(String value) {
    this.fullName = value;
}

/**
 * Gets the value of the eMail property.
 * 
 * @return
 *     possible object is
 *     {@link String }
 *     
 */
public String getEMail() {
    return eMail;
}

/**
 * Sets the value of the eMail property.
 * 
 * @param value
 *     allowed object is
 *     {@link String }
 *     
 */
public void setEMail(String value) {
    this.eMail = value;
}

/**
 * Gets the value of the isPosUser property.
 * 
 */
public boolean isIsPosUser() {
    return isPosUser;
}

/**
 * Sets the value of the isPosUser property.
 * 
 */
public void setIsPosUser(boolean value) {
    this.isPosUser = value;
}

}

我尝试在身份验证后在jsp文件中获取此值：

<%
    SoapUsernamePasswordAuthenticationToken retVal = (SoapUsernamePasswordAuthenticationToken) SecurityContextHolder.getContext().getAuthentication();
    UserInfo userInfo = retVal.getUserInfo();
    boolean isPosUser = userInfo.isIsPosUser();
%>

这里抛出异常。如果我从我的spring应用程序中删除此方法调用，一切正常。问题出在userInfo.isIsPosUser（）;但无法弄清楚是什么原因。

提前致谢！

您在scriptlet中错过了类型化的issUes（）

boolean isPosUser = userInfo.IsPosUser();

而不是：

boolean isPosUser = userInfo.isIsPosUser();

HTTP状态500 - 无法为JSP编译类，该方法未定义
