xfire 调用问题

我用SPRING + Xfire 
在调用服务端方法时 每调用一次 就会出现ERROR [http-8080-Processor24] WSS4JInHandler.invoke(271) | org.apache.ws.security.WSSecurityException: WSHandler: Signature: no crypto properties
 
异常 但是却能调用该方法 这是什么问题 怎样解决？客户端：public static void main(String[] args) {
WSS4JOutHandler wsOut;
Client client;
try {

/**
 * 动态访问
 */

client = new Client(new URL(
"http://localhost:8080/PYPproject/getlistservice.ws?wsdl"));

Properties properties = new Properties();
properties.setProperty(WSHandlerConstants.ACTION,
WSHandlerConstants.SIGNATURE);
// 私钥名字
properties.setProperty(WSHandlerConstants.USER, "ws_security");
// properties文件URL
properties.setProperty(WSHandlerConstants.SIG_PROP_FILE,
"outsecurity.properties");
// callback类
properties.setProperty(WSHandlerConstants.PW_CALLBACK_CLASS,
PasswordHandler.class.getName()); // 绑定
wsOut = new WSS4JOutHandler(properties); client.addOutHandler(new DOMOutHandler());
client.addOutHandler(wsOut);

String tem = "123456%%2006";
Object[] results = client.invoke("addId",new Object[] { tem });
System.out.println(results[0].toString());

/*Object[] results = client.invoke("sayHello",new Object[] {});
System.out.println((String)results[0]);*/
 client.invoke("Look",new Object[] {});
 
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
