我有一个 Maven 基础 GWT 应用程序。
当我通过 Maven 编译、构建并部署它到 JBoss AS 7.1.1 时，我的 GWT-RPC-Service 出现了 ClassNotFoundException。在我包含之前，我部署了并且可以显示 GWT-Widgets，所以 GWT-Jars 应该在那里......
我的 Maven 依赖项如下所示：
<dependency>
<groupId>com.google.gwt</groupId>
<artifactId>gwt-dev</artifactId>
<version>2.5.0</version>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>com.google.gwt</groupId>
<artifactId>gwt-user</artifactId>
<version>2.5.0</version>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>com.google.gwt</groupId>
<artifactId>gwt-servlet</artifactId>
<version>2.5.0</version>
<scope>compile</scope>
</dependency>
我的 EAR 看起来像这样：
-myEar.ear
| |
| |- core.jar
|
|--|- gwt-ui.war
| |
| |-- gwt-ui
| | |-- gwt
| | |-- sc
| | |-- wgt-ui.nocache.js
| |
| |-- META-INF
| | | (is Empty)
| |
| |-- WEB-INF
| | |-- classes
| | | |
| | | |- mygwtProj.client
| | | | |- services
| | | | | | - MyService.class
| | | | | | - MyServiceAsync.class
| | | | |- dto
| | | | | | - DTO.class
| | | |
| | | |- mygwtProj.server
| | | | |- MyServiceImpl.class
| | |-- deploy
| | |-- lib
| | | | (all gwt-jars-files)
| | |-- beans.xml
| | |-- web.xml
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();
}
我的服务异步
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);
}
我的服务实现
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;
}
}

有人知道出了什么问题吗？
