javax.net.ssl.SSLException: error while writing to socket

[Snigdha Solanki]

Hi,

I am writing a java program that reads the content from a secured site.
It is successfully able to open a URL connection but is not able to read the content type and the length and gives the following exception -

Computed URL is https://www.google.com
Content-type = null
Content-length = -1

Code snippet -

 
   
  URL page = new URL(fullURL); 
  URLConnection urlc = page.openConnection();
  urlc.setUseCaches(false); 
  System.out.println("Content-type = " + urlc.getContentType()); 
  System.out.println("Content-length = " + urlc.getContentLength());                    
                
  BufferedReader br = new BufferedReader(new InputStreamReader(urlc.getInputStream()));
 
 

Any idea as to what is going wrong?

thanks,
Snigdha

You get redirected from https://www.google.com to non-secure http://www.google.com.

Is this what you expected?

One thing to keep in mind is Google's use policy. They specifically do not allow Java HTTPSUrlConnection objects to connect to the Google site. It may be that their server is returning a purposefully bad result.
