점점 NullPointerException이 평민-HttpClient를하고 EWSJavaAPI

Question

내가 EWS 자바 API 1.1.5 을 사용하고 다음과 같이 내가받은 편지함 폴더에 서비스를 결합하는 것을 시도하고있다 :

ExchangeService service = new ExchangeService(); 
     ExchangeCredentials credentials = new WebCredentials(email, password); 
     service.setCredentials(credentials); 
     service.setUrl(new java.net.URI("https://" + host 
       + "/EWS/Exchange.asmx")); 
Folder inbox = Folder.bind(service, WellKnownFolderName.Inbox); 

이 난에서 위의 코드를 호출 jsp 페이지. 내가 평민 - HttpClient를 3.1을 사용하고

:

하지만 난 NullPointerException이을 얻고있다.

이 예외는 tomcat 7에서 실행되는 웹 프로젝트에서 코드를 실행할 때 발생하지만 데스크톱 응용 프로그램에서 코드를 실행하면 정상적으로 작동합니다.

UPDATE :

1 HttpClient를 예외 전에 디버깅 :

2012-11-07/16:37:32.425 [http-bio-8080-exec-2] DEBUG Set parameter http.auth.scheme-priority = [NTLM, Basic, Digest] 
2012-11-07/16:37:32.425 [http-bio-8080-exec-2] DEBUG enter HttpState.setCredentials(AuthScope, Credentials) 
2012-11-07/16:37:32.425 [http-bio-8080-exec-2] DEBUG Set parameter http.socket.timeout = 100000 
2012-11-07/16:37:32.425 [http-bio-8080-exec-2] DEBUG Set parameter http.connection.timeout = 100000 
2012-11-07/16:37:32.425 [http-bio-8080-exec-2] DEBUG enter PostMethod.clearRequestBody() 
2012-11-07/16:37:32.425 [http-bio-8080-exec-2] DEBUG enter EntityEnclosingMethod.clearRequestBody() 

2 EWS 추적 예외 전에 :

<Trace Tag="EwsRequestHttpHeaders" Tid="33" Time="2012-11-07 15:14:24Z"> 
POST /EWS/Exchange.asmx HTTP/1.1 
Content-type : text/xml; charset=utf-8 
Accept-Encoding : gzip,deflate 
Keep-Alive : 300 
User-Agent : ExchangeServicesClient/0.0.0.0 
Connection : Keep-Alive 
Accept : text/xml 


</Trace> 

과 그 다음 보낼 생각 다음 요청 :

<Trace Tag="EwsRequest" Tid="1" Time="2012-11-07 15:18:19Z"> 
<?xml version="1.0" encoding="utf-8"?><soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:m="http://schemas.microsoft.com/exchange/services/2006/messages" xmlns:t="http://schemas.microsoft.com/exchange/services/2006/types"><soap:Header><t:RequestServerVersion Version="Exchange2010_SP1"></t:RequestServerVersion></soap:Header><soap:Body><m:FindItem Traversal="Shallow"><m:ItemShape><t:BaseShape>AllProperties</t:BaseShape></m:ItemShape><m:IndexedPageItemView MaxEntriesReturned="5" Offset="0" BasePoint="Beginning"></m:IndexedPageItemView><m:ParentFolderIds><t:DistinguishedFolderId Id="inbox"></t:DistinguishedFolderId></m:ParentFolderIds></m:FindItem></soap:Body></soap:Envelope> 
</Trace> 

그러나 예외가 아니라 예외가 throw됩니다.

UPDATE2 :는 IP 전화를 처리하기위한 내가 시스코 JTAPI 6.1 라이브러리를 사용하고 있음을 언급하는 것을 잊었다, 그리고 인터넷 검색 후 나는 다음과 같은 문제가 JTAPI의 최신 버전에서 해결되는 것을 발견

CSCtz31973 : Ews request printed is Null in case of StreamingSubscriptionRequest 

무엇 이해, EWS 요청을 null (microsoft webservices 요청을 보낼 수 없습니다), 그래서 jtapi 라이브러리를 업데이트하고 시도해보십시오.

수정 방법을 알려주십시오. 다음과 같이 잭스 - WS-RT 및 SAAJ-API의 항아리를 업그레이드 한 후 해결
