Good Morning:
I have several problems to connect a server I am deploying.
First, I have a web service wsdl in a server I control.
And second, I am programming a java client to connect via https with 8443 port to tomcat webservice to return the data.
I firstly installed the pfx certificate on the server, and it works.
Second, I downloaded the client .cer certificate file from the browser and I have to use it to call the webservice https with 8443 and I am having the same error always.

I used thie same webservice first with 8080 port and it worked perfectly, but now with the certificate it doesn't work.
Can anybody explain to me, which have I to do with the .cer file in the client java project?
Thanks.
On the client side, you probably have to set these properties :
-Djavax.net.ssl.keyStore=path_to_keystore
-Djavax.net.ssl.keyStorePassword=keystore_password
Of course, the keystore contains your certificate (.cer)
Can you post your client code ?

I have checked on the internet but found no good solution or explanation on this issue. Please help..
It was occuring because my Java version was pointed to wrong path and it has different policy files. Thats why it was throwing this error.
Setting java home and path resolved my issue:)

Also I observed when, I am trying to run application using JRE 1.8.172 same code work fine. In windows JRE 1.8.192 also working.
I also added mydomain.com in my DNS. and mydomain.com certificate in my code.

There has been a change in Java 8 update 181 and later with the default settings in JNDI when a client connects to a server using SSL. If the server's certificate hostname doesn't match the host that the client connected to, the connection is rejected with that exact message.
The issue and the workaround are described in the Java 8 update 181 release notes.
We have a client server application which runs using spring remoting framework and we are using jetty server and Java 1.7. We deliver both client and server to the customers.
At one of customer's office, for one of the user login, he is getting this Exception which is mentioned in the title of the postjava.net.SocketException:Unexpected end of file from the server. He is actually doing the search for something which makes a server call and finally he ends up getting this error in the error log.
The weird thing is, nobody else in the Customer's office gets this error. It is very weird.
And also i googled about this exception but did not get appropriate answer.
Please provide your suggestions.

I am trying to build a desktop app in java using facebook API provided by google. I have a number of questions :
1) Do I have to make use of socket programming? (coz I am a newbie and I haven't :/ )
2) And it is giving a java.net.UnknownHost Exception in facebook api when I try to create a auth_token.
Any extra info would be a great help. :)

It sound like your machine can't access api.facebook.com host. Are you using a proxy to connect to Internet?
Try using telnet to make sure the whole computer can connect to the internet (not only your proxy-configured driver):
> telnet api.facebook.com 80

api.facebook.com is the endpoint for the old REST API which is deprecated; you should probably be connecting to graph.facebook.com
Nonetheless, api.facebook.com should be resolvable and still work if you're using the legacy APIs.
This is almost certainly a problem with your network, firewall, computer, DNS, or JDK - its a problem with your code connecting to Facebook, not a problem on Facebook's side
