java Paypal与struts2的集成

我正在尝试整合paypal。我遵循了这个链接中给出的所有步骤：Paypal Integration Wizard

当我点击Paypal按钮时，我得到的错误如下：

javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
    at sun.security.ssl.Alerts.getSSLException(Unknown Source)

    at sun.security.ssl.SSLSocketImpl.startHandshake(Unknown Source)
    at sun.security.ssl.SSLSocketImpl.startHandshake(Unknown Source)

浏览完论坛后，我添加了以下代码：

static public void doTrustToCertificates() throws Exception {
    try{
        Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());
        TrustManager[] trustAllCerts = new TrustManager[]{
            new X509TrustManager() {

                @Override
                public X509Certificate[] getAcceptedIssuers() {
                        // TODO Auto-generated method stub
                        return null;
                }

                @Override
                public void checkServerTrusted(X509Certificate[] arg0, String arg1)
                        throws CertificateException {
                        // TODO Auto-generated method stub
                }

                @Override
                public void checkClientTrusted(X509Certificate[] arg0, String arg1)
                        throws CertificateException {
                        // TODO Auto-generated method stub
                        }
                }
        };

        SSLContext sc = SSLContext.getInstance("SSL");
        sc.init(null, trustAllCerts, new SecureRandom());
        HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
        HostnameVerifier hv = new HostnameVerifier() {
            public boolean verify(String urlHostName, SSLSession session) {
                if (!urlHostName.equalsIgnoreCase(session.getPeerHost())) {
                    System.out.println("Warning: URL host '" + urlHostName + "' is different to SSLSession host '" + session.getPeerHost() + "'.");
                }
                return true;
            }
        };
        HttpsURLConnection.setDefaultHostnameVerifier(hv);
    } catch(Exception e){
        e.printStackTrace();
    }
}

并在调用URL之前调用了该方法。现在我得到一个不同的例外说明

有 Java 编程相关的问题?
