Re: about gmail4j using a http proxy

[Tomas Varaneckas]

It's possible that I couldn't get it to work either. You could try asking people in Gmail4j Google Groups.

Hi Tomas,

 

Thank you for your reply.

My HTTP proxy does not need any credentials; besides, after adding these

            proxyClient.getState().setProxyCredentials(new AuthScope(proxy_host,proxy_port, null), new UsernamePasswordCredentials("", ""));
I still cannot get it to work.

 

In http://code.google.com/p/gmail4j/source/browse/trunk/src/main/java/com/googlecode/gmail4j/http/HttpProxyAwareSslSocketFactory.java?r=32&spec=svn32, I notice in particular the following line in the

    public Socket createSocket() throws IOException {



        //FIXME doesn't work

        log.debug("Creating socket! with proxy: " + proxy.address());



        ProxyClient proxyClient = new ProxyClient();

        proxyClient.getHostConfiguration().setHost("nmap.gmail.com", 993);



        proxyClient.getHostConfiguration().setProxy("**", 123);



        proxyClient.getState().setCredentials(new AuthScope("172.16.1.99", 993),



                new UsernamePasswordCredentials(TestConfigurer.getInstance().getGmailCredentials().getUsername(), 



                        new String(TestConfigurer.getInstance().getGmailCredentials().getPasword())));



        proxyClient.getState().setProxyCredentials(AuthScope.ANY

            , new UsernamePasswordCredentials("tomasv", "***"));



        ProxyClient.ConnectResponse resp = proxyClient.connect();



        return resp.getSocket();

    }

Do you remember whether this proxy functionality ever worked? I would greatly appreciate if you could please point out to me how to achieve connecting to IMAP server through http proxy. If this is all that do the work, I am surprised.

 

Thank you once again!

 

Best regards,

Bin.

Hi Bin,

I haven't looked at Gmail4j for quite a while, but hopefully this source code will be helpful, browse around. It's from a project where proxy settings work:

http://code.google.com/p/hawkscope/source/browse/plugins/gmail/trunk/src/main/java/com/varaneckas/hawkscope/plugins/gmail/GmailCheckerPlugin.java

Try setting proxy credentials:

conn.setProxyCredentials(user,

pass.toCharArray());

Hopefully this helps. Good luck!

Tomas

Hi Tomas,

 

I saw your development of gmail4j can handle gmail using IMAP through an HTTP proxy. But I could not get it to work. I tried to send you a message from your webpage; don't know whether you got it or not.

 

Basically, I managed to get java code for ImapGmailClient to work without any proxy server. But when I use the same code behind a proxy server after adding

((ProxyAware) connection).setProxy(proxy_host, proxy_port);

I just cannot get connection to imap server.

On the other hand, using RssGmailClient, I can get it to work after adding

connection.setProxy(proxy_host, proxy_port);

Here, the proxy_host and proxy_port in both places are the same.

 

In the documentation of gmail4j http://www.varaneckas.com/gmail4j/0.3/apidocs/com/googlecode/gmail4j/javamail/ImapGmailConnection.html , it clearly says:

ImapGmailConnection is ProxyAware, allowing to use JavaMail IMAP via HTTP proxy, which was not possible by JavaMail design.

 

Could you please suggest where I did wrong? Thanks a lot.

 

Best regards,

Bin.
