的Websphere應用8：的DataContentHandler需要類型的類com.sun.jersey.api.view.Viewable的字符串對象，被賦予對象

Question

我有以下代碼

import javax.servlet.http.HttpServletRequest; 
import javax.servlet.http.HttpServletResponse; 
import javax.ws.rs.Consumes; 
import javax.ws.rs.GET; 
import javax.ws.rs.Path; 
import javax.ws.rs.core.Context; 
import javax.ws.rs.core.MediaType; 
import javax.ws.rs.core.Response; 
import javax.xml.rpc.ServiceException; 
... 
import com.google.gson.Gson; 
import com.google.gson.GsonBuilder; 
import com.sun.jersey.api.view.Viewable; 
@Path("/test") 
public class TestResource { 
@GET 
public Response getMessage(@Context final HttpServletRequest request, 
     @Context final HttpServletResponse response) throws MalformedURLException, RemoteException, ServiceException, StdAddFault{ 
     ... 
     //Works fine 
//  return Response.ok(ret.toString()).type(MediaType.TEXT_PLAIN).build(); 
     //Throws Exception 
    return Response.ok(new Viewable("/app/jsp/test.jsp")).type(MediaType.TEXT_HTML).build(); 
} 
} 

應用結構是

webapp 
->jsp 
->WEB-INF 

我得到的例外是

錯誤500：javax.servlet.ServletException：java.io.IOException異常：" text/html的"的DataContentHandler需要String對象，給出類型類com.sun.jersey.api.view.Viewable

但是，這似乎符合所有的例子我能找到的對象。

此代碼的工作對我來說：

import com.sun.jersey.api.view.Viewable; 

import javax.servlet.http.HttpServletRequest; 
import javax.servlet.http.HttpServletResponse; 
import javax.ws.rs.GET; 
import javax.ws.rs.Path; 
import javax.ws.rs.core.Context; 
import javax.ws.rs.core.MediaType; 
import javax.ws.rs.core.Response; 
import java.net.MalformedURLException; 

@Path("/test") 
public class TestResource { 
    @GET 
    public Response getMessage(@Context final HttpServletRequest request, 
           @Context final HttpServletResponse response) throws MalformedURLException{ 
     return Response.ok(new Viewable("/dummy.jsp")).type(MediaType.TEXT_HTML).build(); 
    } 
} 

隨着src這內容/主/ web應用/ WEB-INF/JSP/dummy.jsp

Dummy response 

的服務器是GlassFish 3.1.1 Jersey 1.17

也許是一個糟糕的web.xml配置或可視路徑？ 我JSPTemplatesBasePath

<init-param> 
    <param-name>com.sun.jersey.config.property.JSPTemplatesBasePath</param-name> 
    <param-value>/WEB-INF/jsp</param-value> 
</init-param> 

[編輯] 我的web.xml

<?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"

    </filter> 
    <filter-mapping>

     <error-code>400</error-code> 
     <location>/WEB-INF/jsp/400.jsp</location> 
    </error-page> 
</web-app> 

在可視，你必須把路徑沒有你JSPTemplatesBasePath;）
