问题 I'm developing with Java SE application using Hibernate 4 and c3p0 for communication with MariaDB database. It's long running application, waiting for signals from outside, so sometimes database closes my connections after 8 hours of inactivity. I tried to configure c3p0 connections validating but it's not working. Could you help me? Error log (thrown during named query execution): 2014-10-27 08:10:19.062 ERROR [trans] com.example.runnable.T1 - Exception thrown during event processing,

问题 In an app which I have programmed, I have a java.net.SocketException on a specific computer: java.net.SocketException: Address family not supported by protocol family: connect This specific computer runs Windows 7 32 Bit and is connected to the internet through Local Area Connection (Ethernet). The app runs correctly on other computers, with Windows 7 and Windows 8, connected through Local Area Connection or through Wi-Fi, so I am actually not sure that the problem is programmatic. I have

问题 I'm developing an application for Android 2.2 and LG Black devices. When I run the application on my LG device I get the following SocketException, which is never happen on other devices!

问题 I have a .NET 4.0 C# console application. The application is deployed to a network file share (which I believe is a Windows 2000 Server file server) like this: \\server\share\Apps\Beta\Group\JobName\JobName.exe The agent machine that will execute the application is a Windows 2008 R2 Server, x64. I use a domain user account to run the application from the command line. When run under a certain account we'll call UserBeta , the application throws the following exception when trying to connect

问题 I'm downloading a big file (say around 100mb) and I'm receiving SocketException: Read timed out every now and then. I'm thinking of raising the socket timeout. Actually, I'm thinking of setting the socket timeout to 0 (infinite) as eventually the sizes that the files that my app will be downloading may even go greater than 300mb, or even greater than 300mb. Is this a good practice? Regarding socket timeout, when does the timeout countdown actually starts? I mean, when a socket timeout occurs,

问题 As of yesterday, 3/12/2014 I started getting errors pushing my free Python 3.3, Mongodb, cron app to the Openshift server. There error is OSError: [Errno 98] Address already in use I can get the app to push and run correctly if I do a 'rhc app-force-stop' first then to my push everytime(pain in the butt). It seems like push is no longer stopping the app before the push and restart. Everything was working fine yesterday morning so the issue has cropped up in the last 24 hours. Any comments
