我有一個webservice和他的客戶端之間的安全問題。 我使用Axis2和Rampart構建自下而上的web服務，並從生成的wsdl創建客戶端。 我向你展示我的代碼和具體問題。Axis2 + Rampart WebService簽名和加密

int usage = pwcb.getUsage();
if (usage == WSPasswordCallback.DECRYPT || usage == WSPasswordCallback.SIGNATURE) {

OK 。我有一個稱爲「服務器」的WebService，其中一個函數「getWelcome」返回了一個簡單的String。 Importent只是安全性。
問題： 如果我執行我的客戶端，他返回一個NullPointerException並且他沒有與服務連接。這條線拋出該異常：
GetWelcomeResponse response = stub.getWelcome();
但是，如果我禁用壁壘模件，然後我得到的服務的連接，但他錯過了安全頭。問題是這條線：
client.engageModule("rampart");
任何人都可以幫助我嗎？
