在以东道方式管理我的WT申请(gwt 2.0.4)时,我收到了GWT序列化例外:

INFO: GwtRpcEventSrvc: ERROR: The serialization policy file  /84EC7BA65AF8175BAA99B47877FDE163.gwt.rpc  was not found; did you forget to include it in this deployment?

Hosted mode generates serializations policy files (*.gwt.rpc) with different md5 that those that were created during GWT compilation - these are deployed on my server. GWT is missing serialization policy file that hosted mode client wants.

在以非敌对方式行事时,一切都是罚款的。

我试图通过Ant或Eclipse debug配置启动模式,结果相同。 GWT汇编班次和东道模式班次(包括)相同。

GWT Compilation Ant script:

<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="${dir.build.root}/ProjectC/src" />

主办模式发射——文字:

RPC 方法签名:

public List<MyData> getSmpeWorkDddefZonesData(String processId);

MyData 下定义(在作为非GWT项目――数据级的项目E中宣布):

package com.mypackage.data;

import java.io.Serializable;

public interface MyData extends Serializable {...

MyData is linked in module inherited from another GWT module: com.mypackage.Data.gwt.xml:

<module>
  <source path="data" />
</module>

主要模块com.myapp.Main.gwt.xml:

...
  <inherits name="com.mypackage.Data" />
...

如何使东道国产生相同的序列化政策档案?
