I know, there are many different questions and so many answers about this problem... But I can't understand... I have: ubuntu-9.10-desktop-amd64 + NetBeans6.7.1 installed "as is" from off. rep. I need connecting to some site over the HTTPS. For this I use Apache's HttpClient. From tutorial I read: "Once you have JSSE correctly installed, secure HTTP communication over SSL should be as simple as plain HTTP communication." And some example:
HttpClient httpclient = new HttpClient();
GetMethod httpget = new GetMethod("https://www.verisign.com/");
try {
httpclient.executeMethod(httpget);
System.out.println(httpget.getStatusLine());
} finally {
httpget.releaseConnection();
}
By now, I write this:
HttpClient client = new HttpClient();
HttpMethod get = new GetMethod("https://mms.nw.ru");
//get.setDoAuthentication(true);
try {
int status = client.executeMethod(get);
System.out.println(status);
BufferedInputStream is = new BufferedInputStream(get.getResponseBodyAsStream());
int r=0;byte[] buf = new byte[10];
while((r = is.read(buf)) > 0) {
System.out.write(buf,0,r);
}
} catch(Exception ex) {
ex.printStackTrace();
}
As a result I have a set of errors:

========================================================== What have I to do to create simplest SSL connection? (Probably without KeyManager and Trust manager etc. while.)
