我正在使用jersey（而不是maven）开发web服务。我收到错误，如下面的堆栈跟踪（错误500）所示。我安装了apache tomcat6作为本地服务器。

REST Service Invoked Successfully..
我已经创建了一个客户端程序（如指定http://crunchify.com/create-very-simple-jersey-rest-service-and-send-json-data-from-java-client/），如下所示.Below是myclient程序......
public class Client {
//"http://localhost:8080/Snapshothealthapp1/rest/json/product/get"
public static void main(String[] args) {
BufferedReader in=null;
try {
String JSON_DATA =
"{"
+ " \"SnapshotRequest\": ["
+ " {"
+ " \"AuthenticationType\": \"email\","
+ " \"EmailAddress\": \"test@gmail.com\","
+ " \"Password\" : \"12345\","
+ " \"PracticeID\" : \"null\","
+ " \"DeviceID\" : \"null\""
+ " } ]"
+ "}";
System.out.println("declared string in json format" + JSON_DATA);
JSONObject jsonObject = new JSONObject(JSON_DATA);
System.out.println(jsonObject);
URL url = new URL("http://localhost:8080/Snapshothealthapp1/v1/bharathi/vishnu");
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestProperty("Content-Type","application/json; charset:ISO-8859-1;");
connection.setDoOutput(true);
connection.connect();
System.out.println("connection completed");
OutputStreamWriter out = new OutputStreamWriter(connection.getOutputStream());
out.write(jsonObject.toString());
System.out.println(""+connection.getResponseCode());
if(connection.getResponseCode() == 200)
{
System.out.println("success");
in = new BufferedReader(new
InputStreamReader(connection.getInputStream()));
}
else
{
System.out.println("error");
in = new BufferedReader(new
InputStreamReader(connection.getErrorStream()));
System.out.println("error stream...."+connection.getErrorStream());
}
out.close();
System.out.println("close connection");
String s= in.readLine();
int[] m= new int[2];
System.out.println("read from server" +s);
while (in.readLine() != null) {
}
System.out.println("\nREST Service Invoked Successfully..");
in.close();
} catch (Exception e) {
System.out.println("\nError while calling REST Service");
System.out.println(e);
}
}
}
我的服务器看起来像
@Path("/bharathi")
public class Test {
@POST
@Path("/vishnu")
@Consumes(MediaType.APPLICATION_JSON)
public Response crunchifyREST(InputStream incomingData) {
StringBuilder crunchifyBuilder = new StringBuilder();
try {
BufferedReader in = new BufferedReader(new InputStreamReader(incomingData));
String line = null;
while ((line = in.readLine()) != null) {
crunchifyBuilder.append(line);
}
} catch (Exception e) {
System.out.println("Error Parsing: - ");
}
System.out.println("Data Received: " + crunchifyBuilder.toString());
// return HTTP response 200 in case of success
return Response.status(200).entity(crunchifyBuilder.toString()).build();
}
}
我坐在这前面最后4个小时。我无法弄清楚这里发生了什么。我无法从那里得到答案......我得到的错误没有500 ..
在我的浏览器（chrome）上测试了网址后，我得到了以下内容......
HTTP Status 500 - Servlet.init() for servlet jersey-servlet threw exception

这是否与我的本地服务器有关？任何帮助都会非常明显......提前谢谢.....
