how are you?
Well, the problem is that we are using Axis1 to consume a wsdl based webservice which works fine when the URL where the WSDL is located uses plain old HTTP connection, but when it uses a SSL secured conection it brings a ConnectionException when Axis1 tries to download the WSDL document content.
Even reading comments on XMLUtils.class the Axis developers aren't even sure if it will work with HTTPS as it reads on line 810.
Is there any way to solve this? Whe tried to install the certificates on the computer, on ...jre7/lib/security/cacerts and tried to trust all certificates but the problem persists...
Thanks in advance.
Edit:
You can reproduce the Exception with this code:
InputSource source = new InputSource(urlWSDL);
DocumentBuilder db = DocumentBuilderFactoryImpl.newInstance().newDocumentBuilder();
Document doc = (Document) db.parse(source);
The Exception is:

The problem was the Company Proxy, so I've appended:
System.setProperty("https.proxySet", "true");
System.setProperty("https.proxyHost", this.getConfiguracionProxy().getUrlProxy());
System.setProperty("https.proxyPort", this.getConfiguracionProxy().getPuertoProxy());
To:
System.setProperty("http.proxySet", "true");
System.setProperty("http.proxyHost", this.getConfiguracionProxy().getUrlProxy());
System.setProperty("http.proxyPort", this.getConfiguracionProxy().getPuertoProxy());
I've found the solution looking at Wireshark. When I was getting the file on SoapUI or on a web browser, the IP was other than the IP used by our application (the true IP). Then I realized that I was behind a proxy.
I've never used Wireshark... I've learned a lot, which is a good thing.
This sets as a System property the stored proxy configuration.
Thanks everybody.

I'm trying to consume a webservice using JAX-WS client and https.
The problem now is that i successfully created an instance of the service and get the port of the service but when trying to consume a service using that port it gives connection timeout.

Make sure service is running using SOAP,
if it's then try increasing the time
if still not working, try to change the port
Make sure the web service is running. You can use a tool such as SoapUI (free) to test SOAP web services.
I have problem to call locally (localhost) webservice from my Java client application to server application running on Java AS (wildfly10).
I used VM argument
-Djava.net.preferIPv4Stack=true
which was advice in other questions. There is VPN (Cisco AnyConnect) running (because there is one more WS that server application calls as client to remote server). The most probably the VPN is cause of my trouble, because without VPN running I am able to call WS. Is there any setting that make this working?

I am trying to execute a crawler program from my office. A very basic one which is available in internet and which works fine in my home PC. However while I am trying to run the same program in my office PC i am getting connect timed out error. I thought it was proxy problem and tried accessing some site from eclipse internal browser and it worked fine also.
Document doc = Jsoup.connect("http://flipkart.com/").timeout(0).get();

How can I fix this problem?
#alkis made the suggestion:
Try setting a user agent. ff you are using a proxy check this other question:
How to add proxy support to Jsoup (HTML parser)?
Try using:
System.out.println("Testing JSOUP\n--------------");
Proxy proxy = new Proxy( //
Proxy.Type.HTTP, //
InetSocketAddress.createUnresolved("www.yourPROXY.com", 80) //
);
Document doc = Jsoup.connect("http://en.wikipedia.org/").proxy(proxy).get();
Elements newsHeadlines = doc.select("#mp-itn b a");
System.out.println(newsHeadlines.html());

At first I thought may be server is not able to fetch External CSS. So I saved html string as html file and I am able to see the page on browser. That means server is able to access the CSS.
You may still be right about your CSS, since the fact that the main html has been saved does not mean that the CSS is well saved (actually, we don't even know if it tries to save it, have you tried to do your work through a proxy like Paros in order to know every communication you attempt?)
http://sourceforge.net/projects/paros/
By the way, your problem may be different. Are you behind a corporate proxy in your production environment? Does your "flying saucer pdf library" need any external resource (any .xsd or something like that) that could be stuck in the firewall and cause that time-out? Make sure that you have under controll all the communication your application generates and you will find your problem.
I am using the method openStream with Java
in = new BufferedReader(new InputStreamReader(url.openStream(), "UTF-8"));
How long is the method waiting of a response from the service where the URL is sended?
I am becoming same times errors messages like this and i don't know why.

Thanks
openStream() method is a shortcut for URL.openConnection().getInputStream()
you can set the timeout by yourself:
URLConnection con = url.openConnection();
con.setConnectTimeout(XXX);
From the JDK:
"If the timeout expires before the connection can be established, a java.net.SocketTimeoutException is raised. A timeout of zero is interpreted as an infinite timeout."
The default timeout is 0
Your Exception "Thrown to indicate that the IP address of a host could not be determined."
It seems that you might be behind a firewall, so you can add:
System.setProperty("java.net.useSystemProxies", "true"); //if you have set system proxy
or
System.setProperty("http.proxySet","true");
System.setProperty("proxyPort","port");
System.setProperty("proxyHost","proxyhost");
System.setProperty("http.proxyUser", "user" );
System.setProperty("http.proxyPassword", "password" );
to the related java class
java.net.UnknownHostException: dev.virtualearth.net implies that your DNS configuration is incorrect since Java doesn't know how to resolve dev.virtualearth.net to an IP address. What is the string representation of the URL you are opening?
