Maven2的多模块EJB 3.1项目 - 部署错误

的问题是taht我收到以下错误qhile部署我的项目到GlassFish：Maven2的多模块EJB 3.1项目 - 部署错误

java.lang.RuntimeException: Unable to load EJB module. DeploymentContext does not contain any EJB Check archive to ensure correct packaging

但是，让我们开始在项目结构看起来像在Maven2的...

我已经建立了以下情况：

MultiModuleJavaEEProject - 父模块
- >模型--->打包成JAR
- > EJB1 ----> packag ED作为EBJ
- > EJB2 ---->打包为EBJ
- >网站---->打包为战争

所以模型，EJB1，EJB2和网络是儿童/父MultiModuleJavaEEProject的模块。

_ejb1取决于型号。
_ejb2依赖于ejb1。
_web依赖于ejb2。

聚甲醛的样子：

和模型仅仅是一个简单的POJO：

package testing.model; 
public class Data { 
    private String data; 
    public String getData() { 
     return data; 
    } 
    public void setData(String data) { 
     this.data = data; 
    } 
}

而且EJB1只包含一个无状态EJB。

package testing.ejb1; 

import javax.ejb.Stateless; 
import testing.model.Data; 

@Stateless 
public class DataService { 
    private Data data; 
    public DataService(){ 
     data = new Data(); 
     data.setData("Hello World!"); 
    } 
    public String getDataText(){ 
     return data.getData(); 
    } 
}

还有EJB2仅仅是一个无状态EJB：

package testing.ejb2; 

import javax.ejb.EJB; 
import javax.ejb.Stateless; 
import testing.ejb1.DataService; 

@Stateless 
public class Service { 
    @EJB 
    DataService service; 

    public Service(){ 

    } 
    public String getText(){ 
     return service.getDataText(); 
    } 
}

和Web模块中只包含一个Servlet：

package testing.web; 

import java.io.IOException; 
import java.io.PrintWriter; 
import javax.ejb.EJB; 
import javax.servlet.ServletException; 
import javax.servlet.http.HttpServlet; 
import javax.servlet.http.HttpServletRequest; 
import javax.servlet.http.HttpServletResponse; 
import testing.ejb2.Service; 

public class SimpleServlet extends HttpServlet { 

    @EJB 
    Service service; 

    public void doGet(HttpServletRequest request, 
         HttpServletResponse response) 
     throws ServletException, IOException { 

     PrintWriter out = response.getWriter(); 
     out.println("SimpleServlet Executed"); 
     out.println("Text: "+service.getText()); 
     out.flush(); 
     out.close(); 
    } 
}

并在Web web.xml文件模块看起来像：

<!DOCTYPE web-app PUBLIC 
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" 
"http://java.sun.com/dtd/web-app_2_3.dtd" > 

<web-app> 
    <display-name>Archetype Created Web Application</display-name> 
    <servlet> 
    <servlet-name>simple</servlet-name> 
    <servlet-class>testing.web.SimpleServlet</servlet-class> 
    </servlet> 
    <servlet-mapping> 
    <servlet-name>simple</servlet-name> 
    <url-pattern>/simple</url-pattern> 
    </servlet-mapping> 
</web-app>

所以没有进一步的文件由我设置。在任何ejb文件中都没有ejb-jar.xml，因为我使用的是EJB 3.1。所以我认为ejb-jar.xml描述符是可选的。我这是正确的？
但问题是，已经提到的错误：

java.lang.RuntimeException: Unable to load EJB module. DeploymentContext does not contain any EJB Check archive to ensure correct packaging

任何人可以帮助？

我不知道为什么你有web.xml（而不是使用注释）......但如果你真的想，改变这种：

<!DOCTYPE web-app PUBLIC 
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" 
"http://java.sun.com/dtd/web-app_2_3.dtd" >

进入这个：

<?xml version="1.0" encoding="UTF-8"?> 
<web-app xmlns="http://java.sun.com/xml/ns/javaee" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" 
version="3.0"> 
    <display-name>Archetype Created Web Application</display-name> 
    ... 
</web-app>

并重建/重新部署。

非常感谢sooo！而已！ – gerry 2010-03-25 12:49:37

对于任何使用Glassfish 3.1和Eclipse 3.7，m2e 1.0和m2e-wtp集成：的人来说，Eclipse WTP for Glassfish开始部署分解罐，这些罐是buggy in Glassfish 3.1。至少使用Glassfish 3.1.1 Beta 1来使Eclipse WTP集成再次工作。

要测试您是否受此问题影响，请测试从Eclipse导出WAR并使用Glassfish管理控制台手动部署WAR时是否一切正常。
