  • What's the cause of (and treatment for) this java MySQL exception?

    - by justkevin
    I'm getting the following exception when executing the first preparedstatement after a period of inactivity: com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure The last packet successfully received from the server was 2,855,054 milliseconds ago. The last packet sent successfully to the server was 123 milliseconds ago. at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(Unknown Source) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(Unknown Source) at java.lang.reflect.Constructor.newInstance(Unknown Source) at com.mysql.jdbc.Util.handleNewInstance(Util.java:406) at com.mysql.jdbc.SQLError.createCommunicationsException(SQLError.java:1074) at com.mysql.jdbc.MysqlIO.reuseAndReadPacket(MysqlIO.java:3052) at com.mysql.jdbc.MysqlIO.reuseAndReadPacket(MysqlIO.java:2938) at com.mysql.jdbc.MysqlIO.checkErrorPacket(MysqlIO.java:3481) at com.mysql.jdbc.MysqlIO.sendCommand(MysqlIO.java:1959) at com.mysql.jdbc.MysqlIO.sqlQueryDirect(MysqlIO.java:2109) at com.mysql.jdbc.ConnectionImpl.execSQL(ConnectionImpl.java:2648) at com.mysql.jdbc.PreparedStatement.executeInternal(PreparedStatement.java:2077) at com.mysql.jdbc.PreparedStatement.executeQuery(PreparedStatement.java:2228) This only shows up if my application hasn't communicated with MySQL recently. Subsequent queries execute normally. I suspect it's some kind of timeout issue, but the periods of inactivity are way below the 8 hour timeout for MySQL. Any suggestions?

  • How to sort a Map<Key, Value> on the values in Java?

    - by Abe
    I am relatively new to Java, and often find that I need to sort a Map on the values. Since the values are not unique, I find myself converting the keySet into an array, and sorting that array through array sort with a custom comparator that sorts on the value associated with the key. Is there an easier way?

  • How to cause AggregateException with TPL?

    - by Sly
    I'm trying to recreate the conditions that will cause this exception: System.AggregateException: A Task's exception(s) were not observed either by Waiting on the Task or accessing its Exception property. As a result, the unobserved exception was rethrown by the finalizer thread.` I wrote this program thinking I'd cause the exception but it does not: using System; using System.Threading.Tasks; namespace SomeAsyncStuff { class Program { static void Main(string[] args) { Task.Factory.StartNew(() => { throw new NullReferenceException("ex"); }); GC.Collect(); Console.WriteLine("completed"); } } } In my real application, I use TPL and I did not code my exception handling right. As a result I get that exception. Now I'm trying to recreate the same conditions in a separate program to experiment with unobserved exceptions.

  • Google Maps: How to add HTML elements to specific coordinates ?

    - by Christian Toma
    I would like to know how and if I can add standard HTML elements (div, button) to a specific set of coordinates on the map ? For example I have a set of coordinates and I would like to attach a custom balloon notification to them and when I pan away from the coordinates the element should disappear and when I pan back to them, the element should reappear. Is it possible to do this with Google Maps ?

  • Exception declared on ANTLR grammar rule ignored

    - by Kaleb Pederson
    I have a tree parser that's doing semantic analysis on the AST generated by my parser. It has a rule declared as follows: transitionDefinition throws WorkflowStateNotFoundException: /* ... */ This compiles just fine and matches the rule syntax at the ANTLR Wiki but my exception is never declared so the Java compiler complains about undeclared exceptions. ./tool/src/main/antlr3/org/antlr/grammar/v3/ANTLRv3.g shows that it's building a tree (but I'm not actually positive if it's the v2 or v3 grammar that ANTLR 3.2 is using): throwsSpec : 'throws' id ( ',' id )* -> ^('throws' id+) ; I know I can make it a runtime exception, but I'd like to use my exception hierarchy. Am I doing something wrong or should that syntax work?

    - by armmer
    I'm trying to add a custom sort method to the Issue.rb model in Redmine from the redmine_task_board plugin.

Thank you for any help.

  • Why not use PHP's built-in session handling?

    - by Dougal
    Is there currently - or has there ever been - any serious or significant problem with PHP's built-in session handling? I mean, it's always worked for me and my projects. But I see some codebases and frameworks out there seem to use a custom handler. Is this reinventing the wheel? Or improving on some flaws? What flaws?

  • calling Greasemonkey functions from web page

    - by well son
    Hi Can I call function() of my custom Greasemonkey from my page? For example, I created a GM script that contains do_this() function. I want my-web-site.com call the do_this() function. But I can't. I know, I can by doing unsafeWindow.do_this() but doing so prevents me from calling GM_xmlhttpRequest(). Any ideas?

  • lift `??` construct and maven example

    - by coubeatczech
    Hi, I have browsed lift's MegaProtoUser and encountered this construction: ??("Last Name"). Can anyone explain, what that means? Also, I didn't find a way how to add a custom field into MegaProtoUser. The maven's lift's basic archetype defines another field, but it never shows anywhere. (Version 1.0) Thanks for answering

  • Use WPF DLL Assembly in ASP.NET problem

    - by liimur
    Hello, I have C++ project that compiles as DLL Assembly in .NET 3.5 SP1 Project is used for Image rendering processing by using WPF (it loads 2 images from local folder, applies one image on another and saves the output file in the same folder). I want to use that that project as a reference in ASP.NET project to the rendering on the website. So I created simple Web Project in ASP.NET C# that uses C++ project as a Reference. Everything works great in ASP.NET Web Development Server (built-in Web server in VS2008). But once I publish this project to IIS on the same Machine or use IIS for debug instead of built-in Web server Image rendering it's not working anymore. I'm not getting any exceptions or error messages, it just output image is not processes as it supposed to be. If anyone know what could cause that I would really appreciate your insight!

  • Separate php.ini file for each Apache virtual host?

    - by Calvin L
    Is it possible to have a separate php.ini file that overrides the default php.ini file for each virtual host? I'm running Apache/2.2.14, PHP 5.3.2-1. For example I have several vhosts pointing to domains in my /var/www/ directory: /var/www/website1.com /var/www/website2.com What I'd like is to be able to place a custom php.ini file in each directory that would override the default values only for that vhost, but keep the original defaults if the value isn't specified: /var/www/website1.com/htdocs/ /var/www/website1.com/php.ini

  • How can my WiX uninstall restore a registry value change?

    - by Thomas
    The installer I'm writing using WiX 3.0 uses a RegistryValue element to modify an existing registry value (originally written by our main product). I'm trying to figure out a way to restore the registry value when the user uninstalls my utility. I'd like to avoid using a custom action, but that might be the only recourse? TIA.

  • how to install mysqlDb for MySQL and Python ON WINDOWS

    - by Spikie
    I AM A NET DEVELOPER TRY TO INSTALL MYSQLDB FOR PYTHON I KEEP HAVING THIS ERROR MESSAGE raise ImproperlyConfigured("Error loading MySQLdb module: %s" % e) django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module: No module named MySQLdb I AM FOLLOWING THIS INSTRUCTION FROM THIS SITE <"http://sourceforge.net/project/shownotes.php?release_id=303257" I DO NOT UNDERSTAND THESE LINES Windows ....... C:... python setup.py install C:... python setup.py bdist_wininst The latter example should build a Windows installer package, if you have the correct tools. In any event, you must have a C compiler. Additionally, you have to set an environment variable (mysqlroot) which is the path to your MySQL installation. In theory, it would be possible to get this information out of the registry, but like I said, I don't do Windows, but I'll accept a patch that does this. I HAVE BEEN SEARCHING FOR ANSWER ALL DAY PLEASE DO ANYBODY REALLY KNOW HOW TO DO THIS OR AT LEAST POINT ME IN THE RIGHT DIRECTION???? THANKS and what is the c compiler for???????

  • How does WAS/IIS manage ServiceHost instances?

    - by foosnazzy
    It appears that WAS will call ServiceHostFactory.CreateHost() once per each service implementation. How does WAS manage the lifetime of the ServiceHost/ServiceHostFactory? We have a custom factory/host that is occasionally being re-initialized. I'm wondering if WAS is recycling itself or it has some other reason to re-create the ServiceHostFactory/ServiceHost. I'm guessing the ServiceHostFactory gets fired up for the AppDomain and is a singleton, can someone confirm?

  • Hiding a deprecated sharepoint web

    - by BeraCim
    Hi all: I want to hide a Sharepoint web that has been deprecated (via custom means) due to the release of a newer version, whether it would be making it invisible in the sites and workspaces, or via some special archiving function provided by Sharepoint. Basically I do not wish the users to be able to see the deprecated site. I was wondering what are the options for doing so, both programmatically or via Sharepoint utils/interfaces? Thanks.
