Java client cannot connect ot Java server, locally, due VPN

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?

Executable jar and database connection error

I made a little project with java and a database. I tryed it on another computer and the executable jar works perfectly except for the methods that need to read or write in a database. If i start it from my IDE (NetBeans) it works fine if i connect to the database. How can i do? The exception that i get is this:

Your jar is trying to to connect to the database on the computer that it is currently running on (localhost). When you move the jar to another computer, Derby is not running on the new computer (now localhost) and you get the connection error. Change the Derby hostname in your configuration or code to the name of a computer that is running Derby.
The Derby docs have a tutorial on using Derby in server mode here: http://db.apache.org/derby/papers/DerbyTut/ns_intro.html#ns_lookat_code. It describes setting a protocol URL for the database:
protocol = "jdbc:derby://localhost:1527/";
"localhost" refers the current computer that the software is running on. Wherever you are defining this protocl URL, set localhost to the domain name of the computer the server is running on.
You'll also need to make sure that you have network connectivity between your client/jar computer and your database (Derby) server. You probably do if they are both on the same network.

Unable to connect to SQL Server 2008 R2 using java connection string

I am not able to connect with SQL server 2008 R2 using java. The same code is working with SQL server 2005.
I have tried to find out the port and ip for the sqlserver service and it is giving me
ip - 0.0.0.0 and port 1434
I tried to use the same connection string that works in SQL Server 2005, but it won't work for me in SQL Server 2008. Here is my connection string:
conn=DriverManager.getConnection(jdbc:sqlserver://127.0.0.1:1434:DatabaseNameconnect?autoReconnect=true,user, password);
This is the Error:
jdbc:sqlserver://127.0.0.1:1434;DatabaseName=connect;user=falcon;Password=admin

Any help ?

There are many possibilities for your problem:
Firewall
No TCP/IP connector
some services are not running
Try to connect with the SQL-management Studio to you database. If this works, try to connect with SQL-Authentification over TCP/IP.
update
Take a look at the Documentation at http://msdn.microsoft.com/en-en/library/ms143693(v=sql.90).aspx

One obvious problem is that SQL Server listens on port 1433, not 1434. I've already answered this question elsewhere, but I can't be sure if it's an exact match for your problem because you haven't told us what error message you get.

Check whether your RMI port on your other machine(s) is closed? jMeter uses 1099 by default.
Use cmd and type:
telnet [ip-address] 1099
You, of course, started the jMeter server on all machines, right?

this problem is resolve
my computer is connected to the internet and when i start jmeter-server its start on public ip.
my ip is 192.168.137.1 but some how its start on my public ip when i check on google with my public ip is same
i stop internet and start jmeter-serrver again its working
thanks

The above problem occurs when there is a PROXY problem occurs.
There are 2 ways to resolve this.
I was facing the same problem while creating a SOAP Envelope and calling a web service.
When I tried testing this request created by my code from SOAP-UI Client, it was working absolutely fine because I have set the proxy, username & password.
But When I tried to fetch the response by calling the web service from Eclipse code itself, this did not work for me.
I also tried to set the proxy object within Network Connections tab in Eclipse.
For this, I changed the initial setting from Native TO Manual & simply added my proxy, username & password.
But unfortunately, this also did not work for me.
I then simply added 1 line of code to pick up system set proxy within my code & this has resolved my problem.
You have to add : System.setProperty("java.net.useSystemProxies", "true");
This will simply pick up system set proxies within your code & will work fine.
If this is also not working, your request object has got some problem for sure.

Exception says :
Caused by: java.net.ConnectException: Connection timed out: connect
The URL you are trying to access for WebService isn't accessible from your machine.
double check it by ping, is there any proxy settings , firewall . ..etc.
