我是新的码头，我试图在这里运行示例程序“ http://www.codeproject.com/Articles/128145/Run-Jetty-Web-Server-Within-Your-Application ”但我在遇到错误消息我的页面“ 的http：//本地主机：8585 / runJetty / ” 

"HTTP ERROR: 503
Problem accessing /runJetty/. Reason: 
    Service Unavailable

错误日志我从月食得到：

Answer 1:

2012-04-20 11：14：32.617：WARN：oejx.XmlParser：致命@文件：/ C：/用户/ *** /工作区/测试/ WEB-INF / web.xml中线：1栏：7：有机.xml.sax.SAXParseException：处理指令目标匹配 “[XX] [mm]的[11]” 是不允许的。

您登录说，你在web.xml的格式不正确。 行1，式柱7.它可以是UTF-8 字节顺序标记

尝试验证，您的XML是简洁（wellformed）并没有一个BOM。 Java不使用的材料明细表。



Answer 2:

其实，我解决了这个问题。 我用日食码头插件运行。

  1. 我没有在我的日食的JDK的lib，这就是为什么该消息继续显示，我需要安装了完整的JDK，这是最主要的原因。

  2. 我装码头插件的两个版本，至极是jetty7和jetty8。 我想他们彼此什么冲突，所以我删除了jetty7，和它的作品！



Answer 3:

这些答案都不为我工作。

我不得不删除所有已部署的Java Web应用程序：

  • 在Windows /显示视图/其他...
  • 围棋服务器文件夹并选择“服务器”
  • 在本地主机上的J2EE预览右击
  • 点击添加和删除...点击删除所有

然后在服务器上运行项目

该错误消失了！

你将不得不部署另一个项目，因为它不会被服务器发现之前停止服务器。 否则，你会得到一个404错误



Answer 4:

我有同样的问题。 我通过从XML文件中的换行符解决它。 我做了 

<operationBindings>
    <OperationBinding>
        <operationType>update</operationType>
        <operationId>makePdf</operationId>
        <serverObject>
            <className>com.myclass</className>
            <lookupStyle>new</lookupStyle>
        </serverObject>
        <serverMethod>makePdf</serverMethod>
    </OperationBinding>
</operationBindings>

代替 ... 

<serverObject>
            <className>com.myclass
</className>
            <lookupStyle>new</lookupStyle>
</serverObject>


Answer 5:

删除/从工作区中删除的项目。 并重新导入项目到工作区。 这种方法为我工作。



Answer 6:

学习的servlet VS摆幅会有所帮助。 获得从摆动API数据： 

@POST
@Path(“/e”)
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)

public Response api1(String requestJson, public Response api1(String requestJson,                                  @Context HttpHeaders httpHeaders)

{

String h1 = httpHeaders.getHeaderString(“h1”);

switch (h1) {

case “1”: {

if (h1 != null) {

if (validateJsonSyntax(requestJson)) {

ObjectMapper objectMapper = new ObjectMapper();                                try {

Object1 obj = objectMapper.readValue(requestJson, json1.class);        return Response.status(Response.Status.ACCEPTED).build();                                }

catch (Exception e) {

return Response.status(Response.Status.BAD_REQUEST).build();                                }

}

}
}
break;

default:            {            }            break;
}        return Response.status(Response.Status.BAD_REQUEST).build();

}

得到HttpServet处理数据： 

public class c1 extends HttpServlet {

@Override
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {

//super.doPost(request, response);

String h1 = request.getHeader(“h1”);
String h2 = request.getHeader(“h2”);

switch (h1) {

case “one”: {

if (h2 != null) {
InputStream inStrReqBody = request.getInputStream();
if (inStrReqBody != null) {
String strReqBody = IOUtils.toString(inStrReqBody,
request.getCharacterEncoding());
if (validateJsonSyntax(strReqBody)) {
ObjectMapper objectMapper = new ObjectMapper();
try {
Object1 obj1 = objectMapper.readValue(strReqBody, VNFCatalogResponse.class);
response.setStatus(HttpServletResponse.SC_ACCEPTED);
} catch (Exception e) {
\
response.setStatus(HttpServletResponse.SC_BAD_REQUEST);

}
}
}
}
}

}
}
