在TomCat上部署球衣代码后获取异常

[英]Getting exception after deploying jersey code on TomCat

问题描述

我正在学习泽西岛将文件上传到server.Got下面来自net的代码，如果我通过NetBeans运行它，则工作正常，但是如果我通过TomCat部署.war文件，那么我会遇到异常。 

<html>
<body>
<h1>File Upload with Jersey</h1>

<form action="rest/file/upload" method="post" enctype="multipart/form-data">

   <p>
    Select a file : <input type="file" name="file" />
   </p>

   <input type="submit" value="Upload It" />
</form>

</body>
</html>

UploadFileService .class 

@Path("/file")
public class UploadFileService {

@POST
@Path("/upload")
@Consumes(MediaType.MULTIPART_FORM_DATA)
public Response uploadFile(
        @FormDataParam("file") InputStream uploadedInputStream,
        @FormDataParam("file") FormDataContentDisposition fileDetail) {

    String uploadedFileLocation = "d://uploaded/"
            + fileDetail.getFileName().substring(2);


            System.out.println(uploadedFileLocation+"================="+fileDetail.getFileName());
    // save it
    writeToFile(uploadedInputStream, uploadedFileLocation);

    String output = "File uploaded to : " + uploadedFileLocation;

    return Response.status(200).entity(output).build();

}

// save uploaded file to new location
private void writeToFile(InputStream uploadedInputStream,
        String uploadedFileLocation) {

    try {
        OutputStream out = new FileOutputStream(new File(
                uploadedFileLocation));
        int read = 0;
        byte[] bytes = new byte[1024];

        out = new FileOutputStream(new File(uploadedFileLocation));
        while ((read = uploadedInputStream.read(bytes)) != -1) {
            out.write(bytes, 0, read);
        }
        out.flush();
        out.close();
    } catch (IOException e) {

        e.printStackTrace();
    }

}

}

web.xml中 

<web-app id="WebApp_ID" version="2.4"

</web-app>

我引用了此链接，并添加了所有必需的jar文件：

  • 球衣核心，1.18
  • 新泽西州多-1.18
  • 新泽西服务器1.18
  • 新泽西州的servlet-1.18
  • ASM-3.1

我仍然低于例外

2 个解决方案

解决方案1
 1 已采纳  2014-09-17 16:34:15

我发现只有Glassfish才支持Jersey，甚至JBoss和TomCat都不支持

解决方案2
 0  2014-11-30 20:54:44

我正在将Tomcat和Jetty用于Jersey。 因此受到支持。

解决此问题的方法是从此处添加jersey-bundle（ http://mvnrepository.com/artifact/com.sun.jersey/jersey-bundle ）。 从最新版本中选择任何一个。 我用1.8解决了这个问题。
