how to set my TrustManager[] in webdav

Hi,
Is it possible to replace 
"System.setProperty("javax.net.ssl.trustStore", truststore_name)" by 
setting my  trustManagers[] in webdav?

I have the certificate of the server and I want to use the following 
code to create my  trustManagers[] :
-----------------------------------------------------------------------
    private TrustManager[] createMyTrustManagers(X509Certificate 
certificate) {
          TrustManager[] trustManagers = null;
            KeyStore trustStore = KeyStore.getInstance("JKS");
            trustStore.load(null, null);           
                trustStore.setCertificateEntry("server", certificate);
                if (trustStore != null) {                   
                    TrustManagerFactory trustManagerFactory = 
TrustManagerFactory.getInstance("JKS", "SunJSSE");
                    trustManagerFactory.init(trustStore);   
                    trustManagers = trustManagerFactory.getTrustManagers();
                }
           ......
    return trustManagers;
    }
  
Thanks in advance,
Fatiha.
