We are writing to ask about how to solve the problem that we encounter when we are trying to develop the sample of Cisco API application.
We have tried to run the sample of Cisco API sample application from the DevNet form.
Here is the link of the sample that we've tried and followed:
https://developer.cisco.com/site/extension-mobility/learn/sample-apps/index.gsp
package asd;
import java.io.*;
import java.net.*;
import javax.net.ssl.*;
import java.security.*;
import java.security.cert.X509Certificate;
import java.net.URLEncoder;
import javax.xml.ws.Service;
import javax.net.ssl.TrustManagerFactory;
public class asdf {
public static void main(String[] args) throws Exception {
//EM API service URL on Unified CM host host.com
//Note this sample assumes the certificate for the host with subject
//name 'cucm-host.com' has been imported into the Java keystore
//To test with insecure connection use the URL as http://cucm-host.com:8080/emservice/EMServiceServlet
URL url = new URL("https://192.168.10.11:8443/emservice/EMServiceServlet");
//Create a java.net URLConnection object to make the HTTP request
URLConnection conn = url.openConnection();
//setDoOutput=true causes the URLConnection to perform a POST operation
conn.setDoOutput(true);
//The request body will be in HTTP form encoded format
conn.setRequestProperty("Content-Type","application/x-www-form-urlencoded");
//Build a string containing the contents of the E/M API XML request - here 'login'
String EMRequest = "<request><appinfo><appid>operator</appid><appcertificate>operator</appcertificate></appinfo>";
EMRequest += "<login><devicename>SEP000000000001</devicename><userid>user01</userid><deviceprofile>EM-USER01</deviceprofile>";
EMRequest += "<exclusiveduration><time>60</time></exclusiveduration></login></request>";
//URL encode/escape the request
EMRequest = URLEncoder.encode(EMRequest,"UTF-8");
//Build the complete HTTP form request body
EMRequest = "xml="+EMRequest;
//Create an OutputStreamWriter for the URLConnection object and make the request
OutputStreamWriter writer = new OutputStreamWriter(conn.getOutputStream());
writer.write(EMRequest);
writer.flush();
//Read the response
BufferedReader reader = new BufferedReader(new InputStreamReader(conn.getInputStream()));
//Output the response to the console
String line;
while ((line = reader.readLine()) != null) {
System.out.println(line);
}
//Cleanup the stream objects
writer.close();
reader.close();
}
private static void disableSslVerification() {
try
{
// Create a trust manager that does not validate certificate chains
TrustManager[] trustAllCerts = new TrustManager[] {new X509TrustManager() {
public java.security.cert.X509Certificate[] getAcceptedIssuers() {
return null;
}
public void checkClientTrusted(X509Certificate[] certs, String authType) {
}
public void checkServerTrusted(X509Certificate[] certs, String authType) {
}
}
};
// Install the all-trusting trust manager
SSLContext sc = SSLContext.getInstance("SSL");
sc.init(null, trustAllCerts, new java.security.SecureRandom());
HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
// Create all-trusting host name verifier
HostnameVerifier allHostsValid = new HostnameVerifier() {
public boolean verify(String hostname, SSLSession session) {
return true;
}
};
// Install the all-trusting host verifier
HttpsURLConnection.setDefaultHostnameVerifier(allHostsValid);
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
} catch (KeyManagementException e) {
e.printStackTrace();
}
}
}
We have followed the steps, but we can not solve the SSL error:
