将GWT-RPC-Applicaton部署到JBoss AS 7.1.1时出现ClassNotFoundException

我有一个maven base GWT-Application。

当我通过Maven编译，构建并部署到JBoss AS 7.1.1时，我的GWT-RPC-Service获得了ClassNotFoundException。在我包含我已部署并且我可以显示GWT-Widgets之前，所以GWT-Jars应该在那里......

My Maven-Dependencies看起来像这样：

<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

为MyService：

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();
}

MyServiceAsync中

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); 
}

MyServiceImpl 

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;
}
}

任何人都有一个错误的线索？

1 个答案:

答案 0 :(得分：1)

感谢您的输入。 我现在想出了问题。

是一个愚蠢的错误。在maven配置中，我设置了client-Package中的所有Classes都不应该包含在打包中，因为它们被编译为JS。这包括我的服务界面...... 我将它移动到一个新的包共享，并包含在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。

使用此配置，可以使用： - ）
