将GWT RPC应用程序部署到JBoss AS 7.1.1时发生ClassNotFoundException

我有一个基于maven的GWT应用程序

当我在Maven上编译、构建并部署到JBoss 7.1.1时，我得到了一个GWT RPC服务的ClassNotFoundException。在我加入之前，我已经部署并可以显示GWT小部件，所以GWT JAR应该在那里

我的Maven依赖项如下所示：

<dependency>

  <version>2.5.0</version>
  <scope>compile</scope>

我的服务：

import java.util.List;
import com.google.gwt.user.client.rpc.RemoteService;
import com.google.gwt.user.client.rpc.RemoteServiceRelativePath;
import mygwtProj.client.dto.DTO;

@RemoteServiceRelativePath("myService")
public interface ShopService extends RemoteService{
    List<DTO> getAircrafts();
}

有人知道怎么回事吗？

谢谢你的意见。 我现在找出了问题所在

这是一个愚蠢的错误。在maven配置中，我设置了客户端包中的所有类都不应该包含在包中，因为它们都编译为JS。这包括我的服务接口。。。 我将其移动到一个新的共享包中，并将其包含在gwt.xml中

还将gwt user和gwt dev更改为提供的maven范围，将gwt servlet更改为运行时

---

在这种配置下，它可以工作：-）

这不会解决您的问题，但是应该为gwt用户和gwt开发人员提供compile，因为它们在WEB-ING库中不是必需的。GWT最佳实践。@sachinshekharlow，“

编译

不是您所认为的”——）@eagle：与您当前的问题无关：GWT2.5.0中存在影响GWT-RPC的打包缺陷；我们很快就要发布2.5.1了。我想我理解运行时将它们放入Web INF/lib。我原以为只有提供了条件才能避免这种情况。

import java.util.List;
import com.google.gwt.user.client.rpc.AsyncCallback;
import mygwtProj.client.dto.DTO;

@RemoteServiceRelativePath("myService")
public interface ShopService extends RemoteService{
    void getAircrafts(AsyncCallback<List<DTO>> callback); 
}

import java.util.ArrayList;
import java.util.List;
import com.google.gwt.user.server.rpc.RemoteServiceServlet;
import mygwtProj.client.dto.DTO;
import mygwtProj.client.services.MyService;

public class MyServiceImpl extends RemoteServiceServlet implements MyService {
    private static final long serialVersionUID = 1L;

@Override
public List<DTO> getAircrafts() {

    List<DTO> list = new ArrayList<DTO>(1);
    list.add(new ShopItemDTO(1, "man", "typ", 1.0));
    return list;
}
}
