Using installed certificate in creating HTTPSCONNECTION

[Former Member]

Hi,

I have installed the correct certificate of the 3rd party system in my server in the following places in Visual Admin -> Services -> Key Storage:

1. As a default certificate

2. In the J2EE Engine Ticket Key Store

3. In J2EE Trusted CA?s

Now I need to programmatically use this certificate in generating the HTTPS connection from my SAP system to 3rd party system. I am not sure how to go about it. So it would be great if you could help.

Here is my code:

//Start of code

private StringBuffer sendRequest(BufferedReader input) {

StringBuffer serverResponse = new StringBuffer();

StringBuffer toServer = new StringBuffer();

StringBuffer fromServer = new StringBuffer();

try

{

String httpsURL = https://pi.ercot.com/servlet/piController;

try {

URL myurl = new URL(httpsURL);

// keystoreCAs keystore instance with trusted certificates

String ks = KeyStore.getDefaultType();

KeyStore keystoreCAs = KeyStore.getInstance("PKCS12");

keystoreCAs.load(null, null);

// Create factory

SecureConnectionFactory factory = new SecureConnectionFactory(keystoreCAs, null);

// Create the HTTPS connection

HttpURLConnection con = factory.createURLConnection(httpsURL);

con.setUseCaches(false); // Don't look at possibly cached data

con.setDoOutput( true );

con.setDoInput( true );

BufferedWriter br = new BufferedWriter( new OutputStreamWriter( con.getOutputStream() ));

br.write( "input=" );

while ( input.ready() )

{

br.write( (char)input.read() );

}

input.close();

BufferedReader serverReader = new BufferedReader( new InputStreamReader( con.getInputStream() ));

while( serverReader.ready() )

{

serverResponse.append( (char)serverReader.read() );

}

serverReader.close();

connServer.disconnect();

}

catch (MalformedURLException mue) {

System.out.println(httpsURL + " is not a URL that can be resolved");

}

catch (CertificateException ce) {

ce.printStackTrace();

}

}

catch (Exception e) {

e.printStackTrace();

}

return serverResponse;

}

//End of code

Now I am getting an exception as shown below:

iaik.security.ssl.SSLException: Server certificate rejected by ChainVerifier

The line causing this exception is highlighted in BOLD above.

Please let me know the reason for this.

Thanks,

Ajay

Tried out the code given in that particular link. It doesn't seem to help. Still getting the same error.
