的当运行在托管模式下我的GWT应用程序（GWT 2.0.4），调用远程Tomcat上运行RPC方法，我得到GWT序列化异常：GWT序列化政策托管模式不同步

托管模式产生使用不同的md5序列化策略文件（* .gwt.rpc），这些是在GWT编译过程中创建的 - 这些部署在我的服务器上。 GWT缺少托管模式客户端需要的序列化策略文件。
当在非托管模式下运行时，一切都很好。
我试图通过Ant或Eclipse调试配置启动托管模式，结果相同。 GWT编译类路径和托管模式类路径（包括）是相同的。
GWT编译Ant脚本：
<java failonerror="true" fork="true" classname="com.google.gwt.dev.Compiler">
<classpath>
<pathelement location="${basedir}/src" />
<pathelement location="${dir.build.root}/ProjectA/src" />

<pathelement location="../ExternalLibs/libs/gwt-log-3.0.0.jar" />

托管模式启动 - Ant脚本：
<target name="hosted" description="Run hosted mode">
<java failonerror="true" fork="true" classname="com.google.gwt.dev.HostedMode">

RPC方法签名：
public List<MyData> getSmpeWorkDddefZonesData(String processId);
MyData定义（在ProjectE宣称是非-GWT项目 - 数据层）：
package com.mypackage.data;
import java.io.Serializable;
public interface MyData extends Serializable {...
迈德特从其他GWT模块继承模块链接： com.mypackage.Data.gwt.xml：
<module>
<source path="data" />
</module>
主要模块com.myapp.Main.gwt.xml：
...
<inherits name="com.mypackage.Data" />

如何使托管产生相同的序列化策略文件？
感谢，它帮助！只需添加更多细节：我必须使用-war/path/to/my/built/war选项启动托管模式，而不是默认路径。 – foch
