I am having a similar problem.
I have an application running on Websphere 7 Dev environment
http://appl.company.com/appl/home.action
And also on my localhost system
http://localhost/appl/home.action
I am trying to access a URL like below
http://appl.company.com/SiteContent/a.html from the above application
It works perfectly fine on my local system.
But on the development environment, on this particular line :-
String stream = (new java.net.URL(url)).openStream();
I am getting a "java.net.ConnectException: Connection refused" exception
On googling i figured, such problems are either due to one of the following
The port is wrong (cannot be this option, as same url running perfectly from local system)
Firewall is stopping it.
The Android SDK, do you config the path?
try to it what open a cmd window,input 'adb devices',see result waht display a device of you Moto

Remote debugging from eclipse

I am trying to remote a debug an application which is deployed through Websphere. I have all the port configured correctly on server side and on eclipse side. I can use
telnet host port
to connect to remote host and port correctly. But When I try to connect through remote debug through eclipse, I run into the error
Failed to connect to remote VM
com.sun.jdi.connect.spi.ClosedConnectionException
What can be the possible causes for this? I have checked and searched Stackoverflow for this error already. I have tried the most things from answer on this question Eclipse Error: "Failed to connect to remote VM"
I changed the port and it worked. It was a networking issue with that port of 7777.

Please anyone help me regarding, Thanks in advance!!
Looks like your Postgresql daemon is not running. Check if the server has started and is running. I dont know which OS you are using but try ps -ax on linux/mac or the task manager in windows.
Maybe a firewall that is blocking the connection, you have to provide more information about your environment to be sure.

Android Emulator get port Number

The port for emulator 5554 is not working when I try to type the command: telnet localhost 5554
The error is:
Connecting To localhost...Could not open connection to the host, on port 5554:
Connect failed
How could it connect to port 5554 to let the android emulator sending socket, and the android emulator program on client server side give a message that does not work ( unfortunately client has stopped)
Check whether your port is open or not using this link.

If u have personal firewall try disabling that.
