Answer 1

En realidad, he resuelto el problema. Lo ejecuto por eclipse jetty plugin.

1. yo no tenía la lib JDK en mi eclipse, es por eso que el mensaje seguirá mostrando dicho que necesito instalado el JDK completo, esa es la razón principal.

2. Instalé dos versiones de Jetty Plugin, que es jetty7 y jetty8. Creo que entran en conflicto entre ellos o algo así, así que eliminé el jetty7, ¡y funciona!

Answer 2

2012-04-20 11:14:32.617:WARN:oejx.XmlParser:FATAL@file:/C:/Users/***/workspace/Test/WEB-INF/web.xml line:1 col:7 : org.xml.sax.SAXParseException: The processing instruction target matching "[xX][mM][lL]" is not allowed.

que se conecte dice, que web.xml está mal formado. Línea 1, columna 7. Puede ser un UTF-8 Byte-Order-Marker

Intente verificar que su xml esté bien formado y no tenga una lista de materiales. Java no usa listas de materiales.

Answer 3

Tuve el mismo problema. Lo resolví eliminando el salto de línea del archivo xml. Hice

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

en lugar de ...

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

Answer 4

Ninguna de estas respuestas trabajó para mí.

tuve que quitar toda aplicación Java Web desplegado:

• Windows/Show View/Other ...
• Vaya la carpeta del servidor y seleccione "Servidores"
• Haga clic en el J2EE Vista previa en localhost
• clic aquí para agregar y quitar ... Haga clic en Quitar todo

a continuación, ejecute el proyecto en el servidor

¡El error se ha ido!

Deberá detener el servidor antes de implementar otro proyecto porque el servidor no lo encontrará. De lo contrario, obtendrá un error 404

Answer 5

Eliminar/Eliminar el proyecto del espacio de trabajo. y Reimportar el proyecto al espacio de trabajo. Este método funcionó para mí.

Answer 6

Aprender servlet vs swing ayudará. Obtener datos de API Swing:

@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(); 

} 

obtener datos de HttpServet manipuladores:

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); 

} 
} 
} 
} 
} 

} 
}
