我编写了一个调用webservice的客户端。我的客户是：
String publisherEPR = "https://abc:8280/services/ProviderPublication";
protected void publicationOpenSession(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
System.out.println("Inside publicationOpenSession");
date = new Date();
namespace = "http://www.openoandm.org/xml/ISBM/";
fac = OMAbstractFactory.getOMFactory();
OMNamespace ns = fac.createOMNamespace(namespace, "ns1");
OMElement result = null;
channelURI = request.getParameter("TxtPublisher1ChannelURI");
textfield = request.getParameter("TxtAreaServicePublisherLog");
String finalChannelURI = "";
int count = 0;
try {
if (channelURI != null && (channelURI.indexOf(".") > -1)) {
System.out.println("Inside If Checking Channel URI");
String[] tempChannelURI = channelURI.split("\\.");
for (count = 0; count < tempChannelURI.length - 1; count++) {
finalChannelURI = finalChannelURI + tempChannelURI[count];
if (count < tempChannelURI.length - 2) {
finalChannelURI = finalChannelURI + ".";
}
}
System.out.println("Inside If Checking Channel URI : " + finalChannelURI);
}
System.out.println("OpenPublicationSession" + finalChannelURI);
System.out.println(publisherEPR);
OMElement OpenPublicationSessionElement = fac.createOMElement("OpenPublicationSession", ns);
OMElement ChannelURIElement = fac.createOMElement("ChannelURI", ns);
ChannelURIElement.setText(finalChannelURI);
OpenPublicationSessionElement.addChild(ChannelURIElement);
String webinfFolder = request.getSession().getServletContext().getRealPath("/WEB-INF");
ConfigurationContext ctx = ConfigurationContextFactory.createConfigurationContextFromFileSystem(
webinfFolder, webinfFolder + "/conf/axis2.xml");
Options options = new Options();
ServiceClient client = new ServiceClient(ctx, null);
EndpointReference targetEPR = new EndpointReference(publisherEPR);
options.setTo(targetEPR);
options.setAction("urn:OpenPublicationSession");
options.setManageSession(true);
options.setUserName(user_name);
java.util.Map<String, Object> m = new java.util.HashMap<String, Object>();
/*m.put("javax.net.ssl.trustStorePassword", "wso2carbon");
m.put("javax.net.ssl.trustStore", "wso2carbon.jks");
*/
System.out.println(new Date() + " Checkpoint1");
// We are accessing STS over HTTPS - so need to set trustStore parameters.
System.setProperty("javax.net.ssl.trustStore", "client.jks");
System.setProperty("javax.net.ssl.trustStorePassword", "apache");
/*m.put("javax.net.ssl.trustStore", "client.jks");
m.put("javax.net.ssl.trustStorePassword", "apache");*/
/*m.put("org.apache.ws.security.crypto.provider","org.apache.ws.security.components.crypto.Merlin");
m.put("org.apache.ws.security.crypto.merlin.keystore.type", "jks");
m.put("org.apache.ws.security.crypto.merlin.keystore.password","apache");
m.put("org.apache.ws.security.crypto.merlin.file", "client.jks");*/
//options.setProperties(m);
System.out.println(new Date() + " Checkpoint2");
client.setOptions(options);
MessageContext messageContext = new MessageContext();
messageContext.setOptions(options);
messageContext.setMessageID("MyMessageID");
System.out.println("provider:user_name: " + user_name);
messageContext.setProperty("username", user_name);
messageContext.setProperty("password", user_password);
MessageContext.setCurrentMessageContext(messageContext);
messageContext.setProperty("myproperty", "mypropertyvalue");
String falconNS = "http://cts.falcon.isbm";
falcon = fac.createOMNamespace(falconNS, "falcon");
OMElement falconUserElement = fac.createOMElement("FalconUser", falcon);
falconUserElement.setText(user_name);
client.addHeader(falconUserElement);
// invoke web-service
try {
errorText = "Client Didnt Respond.";
result = client.sendReceive(OpenPublicationSessionElement);
System.out.println(result.toString());
OMElement SessionIDElement = null;
SessionIDElement = result.getFirstChildWithName(new QName(namespace, "SessionID"));
SessionID = SessionIDElement.getText();
request.setAttribute("PublisherSession", SessionID);
StringBuffer text = new StringBuffer();
text.append((request.getParameter("TxtAreaServicePublisherLog")).trim());
text.trimToSize();
SessionID = SessionIDElement.getText();
StringBuffer publisherLog = new StringBuffer();
publisherLog.append((request.getParameter("TxtAreaServicePublisherLog")).trim());
publisherLog.trimToSize();
System.out.println("Checkpoint1");
publisherLog.append("\n" + new Date().toString() + " " + PUBLISHER_SESSION_SUCCESS_MSG + SessionID);
request.setAttribute("textMessageService2", publisherLog);
request.setAttribute("PublisherSession", SessionID);
System.out.println("Checkpoint3");
RequestDispatcher rd = request.getRequestDispatcher("/Provider.jsp");// hard-coded
try {
rd.forward(request, response);
} catch (IOException ioe) {
ioe.printStackTrace();
} catch (ServletException se) {
se.printStackTrace();
}
} catch (Exception e) {
errorText = "Client not responding";
buildErrorLog(request, response, e);
e.printStackTrace();
}
//buildCallLog(request, response, result);
} catch (Exception e) {
e.printStackTrace();
buildErrorLog(request, response, e);
}
}
And i have a proxy service upon which i have implemented security and its url is:
https://abc:8280/services/ProviderPublication.
我在回调处理程序中的句柄方法是：
public void handle(Callback[] callbacks) throws IOException, UnsupportedCallbackException {
System.out.println("\n \n " + new Date() + " ISBMClient.PWCBHandler.handle");
if(MessageContext.getCurrentMessageContext() == null){
System.out.println("CurrentMessageContext is null");
}else{
//get the credentials from the jsp
System.out.println("MessageID: " + MessageContext.getCurrentMessageContext().getMessageID());
dynamicUser = MessageContext.getCurrentMessageContext().getProperty("username").toString();
dynamicPassword = MessageContext.getCurrentMessageContext().getProperty("password").toString();
System.out.println("MessageContext user_name: " + dynamicUser);
System.out.println("MessageContext user_password: " + dynamicPassword);
}
for (int i = 0; i < callbacks.length; i++) {
WSPasswordCallback pwcb = (WSPasswordCallback)callbacks[i];
pwcb.setIdentifier(dynamicUser);
String id = pwcb.getIdentifier();
System.out.println("Invoking service with user: " + id);
if(dynamicUser.equals(id)){
pwcb.setPassword(dynamicPassword);
}
}
}
现在的问题是，当我通过我的客户端代码调用此代理服务时，我将获得异常

但是同样的代码正在为另一个用eclipse编写的Web服务工作。我究竟做错了什么？期待您的回答。提前致谢

您需要设置SOAP信封以及从Service Client传输有效负载的SOAP主体。我认为导致这个问题。请参阅此博客文章并重构您的代码以添加它。 http://amilachinthaka.blogspot.com/2009/09/sending-arbitrary-soap-message-with.html

这里的响应有点晚了，但我遇到了同样的错误消息，经过进一步的挖掘后，由于一些SSL证书失败。
有两种方法可以解决这个问题：
OR
使用您自己的自定义代码接受所有证书（例如下面的acceptallCerts()方法）
public class SslUtil {
private static class SmacsTrustManager implements X509TrustManager {
@Override
public void checkClientTrusted(X509Certificate[] arg0, String arg1) throws CertificateException {}
@Override
public void checkServerTrusted(X509Certificate[] arg0, String arg1) throws CertificateException {}
@Override
public X509Certificate[] getAcceptedIssuers() {
return null;
}
}
public static void acceptAllCerts(){
try{
SSLContext ctx = SSLContext.getInstance("TLS");
ctx.init(new KeyManager[0], new TrustManager[] {new SmacsTrustManager()}, new SecureRandom());
SSLContext.setDefault(ctx);
}catch (Exception e){
}
}
}
