  • Hibernate Communications Link Failure in Hibernate Based Java Servlet application powered by MySQL

    - by Vatsala
    Let me describe my question - I have a Java application - Hibernate as the DB interfacing layer over MySQL. I get the communications link failure error in my application. The occurence of this error is a very specific case. I get this error , When I leave mysql server unattended for more than approximately 6 hours (i.e. when there are no queries issued to MySQL for more than approximately 6 hours). I am pasting a top 'exception' level description below, and adding a pastebin link for a detailed stacktrace description. javax.persistence.PersistenceException: org.hibernate.exception.JDBCConnectionException: Cannot open connection - Caused by: org.hibernate.exception.JDBCConnectionException: Cannot open connection - Caused by: com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure - The last packet successfully received from the server was 1,274,868,181,212 milliseconds ago. The last packet sent successfully to the server was 0 milliseconds ago. - Caused by: com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure - The last packet successfully received from the server was 1,274,868,181,212 milliseconds ago. The last packet sent successfully to the server was 0 milliseconds ago. - Caused by: java.net.ConnectException: Connection refused: connect the link to the pastebin for further investigation - http://pastebin.com/4KujAmgD What I understand from these exception statements is that MySQL is refusing to take in any connections after a period of idle/nil activity. I have been reading up a bit about this via google search, and came to know that one of the possible ways to overcome this is to set values for c3p0 properties as c3p0 comes bundled with Hibernate. Specifically, I read from here http://www.mchange.com/projects/c3p0/index.html that setting two properties idleConnectionTestPeriod and preferredTestQuery will solve this for me. But these values dont seem to have had an effect. Is this the correct approach to fixing this? If not, what is the right way to get over this? The following are related Communications Link Failure questions at stackoverflow.com, but I've not found a satisfactory answer in their answers. http://stackoverflow.com/questions/2121829/java-db-communications-link-failure http://stackoverflow.com/questions/298988/how-to-handle-communication-link-failure Note 1 - i dont get this error when I am using my application continuosly. Note 2 - I use JPA with Hibernate and hence my hibernate.dialect,etc hibernate properties reside within the persistence.xml in the META-INF folder (does that prevent the c3p0 properties from working?) edit - Here are the c3p0 parameters I tried out - select 1; 2

  • Silverlight (RIA Services) spontaneous culture changing

    - by Marc Wittke
    My RIA enabled Silverlight Application is setting the thread culture in the App constructor (this is absolutley okay since it is an intranet application and will never ever be used by someone who is not german): public App() { InitializeComponent(); Thread.CurrentThread.CurrentCulture = new CultureInfo("de-DE"); } It does what it should, the DataForms are displaying datetime values in german notation. BUT: it is spontaneously changing to en-US notation when navigating between items in the data source that is bound to the DataForm. Why?

  • Support for encoding query string or POST data in YUI ?

    - by faB
    How do you encode a javascript object/hash (pairs of properties and values) into a URL-encoded query string with YUI (2.7.0 or 3.0.0 Beta) ? I want to do the equivalent of Object.toQueryString() from Prototype: I need this to encode parameters for GET and POST requests with YAHOO.util.Connect. It turns out YAHOO.util.Connect has a setForm() method to serialize a form but that still leaves me out cold to encode parameters for GET requests, or the 4th parameter of YAHOO.util.Connect.asyncRequest() to pass post data.

  • How do you sort a C# dictionary by value?

    - by kurious
    I often have a Dictionary of keys & values and need to sort it by value. For example, I have a hash of words and their frequencies, and want to order them by frequency. There's SortedList which is good for a single value (frequency), but I want to map it back to the word. SortedDictionary orders by key, not value. Some resort to a custom class, but what's the cleanest way?

  • LinkedList parameters in Java

    - by Walt
    Hi there, I created a program that contains linked lists that are passed various methods. While this works just fine in Java... a style checker program we have to use doesn't like it It says: Declaring variables, return values or parameters of type 'LinkedList' is not allowed. If I declare them as simply List then I don't have access to the methods I want. What should I do?

  • Ruby: How can I have a Hash take multiple keys?

    - by zxcvbnm
    I'm taking 5 strings (protocol, source IP and port, destination IP and port) and using them to store some values in a hash. The problem is that if the IPs or ports are switched between source and destination, the key is supposed to be the same. If I was doing this in C#/Java/whatever I'd have to create a new class and overwrite the hashcode()/equals() methods, but that seems error prone from the little I've read about it and I was wondering if there would be a better alternative here.

  • setting z-index jquery ui controls?

    - by maxp
    Annoyingly, the jquery ui's set a few css properties inline, making it impossible to override them in the stylesheet. I tried to override the values with jquery, but then they get changed back as soon as the control is interacted with. Does anyone know if any of the jquery ui control's initialisers/constructors have the ability to override their z-index value or set other css properties?

    Hi, I've been using XPath with Selenium quite happily and even using getEval with a but of Javascript, but a colleague said wouldn't it be great to be able to use JQuery selectors in Selenium. I've googled it, but can't find any articles that seem to work for me. Could anyone provide a comprehensive guide on how to use JQuery syntax to extract doc elements and their respective values out of selenium. I'm using C# to write my selenium tests, so if any examples could be from a C# perspective that'd be great. Thanks
