jboss7.x - 无法编码 EJB 参数 --- IllegalArgumentException : Can not set org. apache.commons.collections.FastHashMap 字段

Question

尝试使用 SearchFacade.java 的远程接口(interface)保存搜索结果时出现以下错误

"Failed to marshal EJB parameters"

Can not set org.apache.commons.collections.FastHashMap field org.apache.commons.validator.Field.hMsgs to org.apache.commons.collections.FastHashMap at sun.reflect.UnsafeFieldAccessorImpl.throwSetIllegalArgumentException(UnsafeFieldAccessorImpl.java:146) at

我正在使用 struts 1.1，EJB 2.1 使用 xdoclet 1.2.3 jar 来生成依赖文件。(这不可避免地要使用)，我的 Local,Home 接口(interface)是使用 Xdoclet 生成的。

我还在我的项目中使用 Java 6、Jboss EAP 6.1 Alpha。

注意:相同的代码在 Jboss 4.0 中运行时运行良好

所以不知道我的远程调用是否正确。

欢迎任何帮助。

Answer 1

作为参数或作为远程调用响应传递的对象必须是可序列化的。

例子:-

public class APIGetVerificationProofs implements Serializable {

    private static final long serialVersionUID = 1L;

    private String id;
    private String fileName;
    private String mimeType;
    private String itemId;
    private String type;
   .
   .
   .
   .
}
