I have a problem with access the gmail from my working area. This is my code. It works in my home when network settings are default. The main problem is, in the working area there is more security on computers and network like firewalls etc..
I have to find a solution for run this script behind the firewall. Closing the firewall is not a permanent solution.
Also I added the error message to the below. Any help is appreciated.

I'm having some issues for creating a simple socket, I'm new to this kind of stuff sorry for a simple question thanks. I tried to follow some tutorial for creating Sockets in java and tried this so far
try {
Socket chatSocket = new Socket("127.0.0.1", 4242);
System.out.println("connection established");
}
catch (IOException e) {
e.printStackTrace();
}
I'm getting this kind of error

System.Net.Sockets.SocketException No connection could be made because the
target machine actively refused it 127.0.0.1:4242
I have no idea what is happening because, just followed what the tutorial does. I think the issue is on my local machine but I have no idea what is making the connection refuse
I am using SoapUI 5.2. When I Start SoapUI, it works fine but after a while, it goes offline and Startup Page keeps on saying 'The page could not be loaded'. The only time it get backs to work is after restarting the PC. I checked the log and found following stacktrace. I've tried forcing IPV4 as per few suggestion. But no luck.

what is RMI registry
http://docs.oracle.com/javase/7/docs/technotes/guides/rmi/faq.html#domain
I have a server which is crashing every few days and I am trying to work out where the problem lies. The software is running in an environment supplied by the customer and i need to know if we are the problem or windows/the network.
My question is... RMI registry, Is that something that java creates or is it something that exists in windows anyway? Why would a connection to localhost suddenly become unavailable or refused? Is there anything that i can do to troubleshoot immediately?
The RMI configuration is here:
<RMIService>
<class>com.s.i.system.RMIService</class>
<server name="Server">
<host>localhost</host>
<timeout>0</timeout>
</server>
</RMIService>
Here is the error that is created in the logs.

The RMI Registry is a component of the JRE, not of Windows. Clearly it is crashing, or far more probably it is being closed down incorrectly for some reason. I've never seen an RMI Registry crash in 18 years.
I have an app stored in digital ocean that before was stored in other server.
Before my app send email normally, now I got error:
I already check firewal stuff, iptables config, change port and etc. In my local environment the email flows normal, if I deploy back in my older server the email flows normal.
What more can be?

In tomcat server.xml, My max threads is 500, acceptCount is 500 and connection timeout is 20000. Still it shows the above mentioned error. I could see a pattern like only those threads between 100-250 are getting failed in consecutive runs. Can someone please help me on this
Please check Database connection pool maxtotal. It might be less and you may need to increase it.
