Getting SSLHandShakeException

While I am accessing the wsdl url I am getting the exception in android

javax.net.ssl.SSLHandshakeException: java.security.cert.CertPathValidatorException: Trust anchor for certification path not found.

i have used ksoap2 library for executing the WSDL file.

I had also implemented certification classes, but i am getting the same issue

please tell if there is any solution for this.

I am using these two classes for certification:

AndroidInsecureHttpsServiceConnectionSE class:

    package com.example.androidwsdltest;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.net.URL;

    public AndroidInsecureHttpsServiceConnectionSE(String host, int port,
            String file, int timeout) throws IOException {
        // allowAllSSL();
        connection = (HttpsURLConnection) new URL("https", host, port, file)
                .openConnection();
        updateConnectionParameters(timeout);
