• Catching error caused by InitialContext.lookup

  - by Martin Schröder

  I'm developing a command line client (Java SE6) that now needs to talk to a Glassfish 2.1 server. The code for setting up this connection is try { final InitialContext context = new InitialContext(); final String ejbName = GeneratorCancelledRemote.class.getName(); generatorCancelled = (GeneratorCancelledRemote) context.lookup(ejbName); } catch (Throwable t) { System.err.println("--> Could not call server:"); t.printStackTrace(System.err); runWithOutEJB = true; } I'm now testing it without a running server and the client (when run from Eclipse 4.2) just bombs with 31.10.2012 10:40:09 com.sun.corba.ee.impl.transport.SocketOrChannelConnectionImpl WARNUNG: "IOP00410201: (COMM_FAILURE) Connection failure: socketType: IIOP_CLEAR_TEXT; hostname: localhost; port: 3700" org.omg.CORBA.COMM_FAILURE: vmcid: SUN minor code: 201 completed: No at com.sun.corba.ee.impl.logging.ORBUtilSystemException.connectFailure(ORBUtilSystemException.java:2783) at com.sun.corba.ee.impl.logging.ORBUtilSystemException.connectFailure(ORBUtilSystemException.java:2804) at com.sun.corba.ee.impl.transport.SocketOrChannelConnectionImpl.(SocketOrChannelConnectionImpl.java:261) at com.sun.corba.ee.impl.transport.SocketOrChannelConnectionImpl.(SocketOrChannelConnectionImpl.java:274) at com.sun.corba.ee.impl.transport.SocketOrChannelContactInfoImpl.createConnection(SocketOrChannelContactInfoImpl.java:130) at com.sun.corba.ee.impl.protocol.CorbaClientRequestDispatcherImpl.beginRequest(CorbaClientRequestDispatcherImpl.java:192) at com.sun.corba.ee.impl.protocol.CorbaClientDelegateImpl.request(CorbaClientDelegateImpl.java:184) at com.sun.corba.ee.impl.protocol.CorbaClientDelegateImpl.is_a(CorbaClientDelegateImpl.java:328) at org.omg.CORBA.portable.ObjectImpl._is_a(ObjectImpl.java:112) at org.omg.CosNaming.NamingContextHelper.narrow(NamingContextHelper.java:69) at com.sun.enterprise.naming.SerialContext.narrowProvider(SerialContext.java:134) at com.sun.enterprise.naming.SerialContext.getCachedProvider(SerialContext.java:259) at com.sun.enterprise.naming.SerialContext.getRemoteProvider(SerialContext.java:204) at com.sun.enterprise.naming.SerialContext.getProvider(SerialContext.java:159) at com.sun.enterprise.naming.SerialContext.lookup(SerialContext.java:409) at javax.naming.InitialContext.lookup(InitialContext.java:392) at com.werkii.latex.generator.Generator.main(Generator.java:344) Caused by: java.lang.RuntimeException: java.net.ConnectException: Connection refused: connect at com.sun.enterprise.iiop.IIOPSSLSocketFactory.createSocket(IIOPSSLSocketFactory.java:347) at com.sun.corba.ee.impl.transport.SocketOrChannelConnectionImpl.(SocketOrChannelConnectionImpl.java:244) ... 14 more Caused by: java.net.ConnectException: Connection refused: connect at sun.nio.ch.Net.connect(Native Method) at sun.nio.ch.SocketChannelImpl.connect(SocketChannelImpl.java:532) at com.sun.corba.ee.impl.orbutil.ORBUtility.openSocketChannel(ORBUtility.java:105) at com.sun.enterprise.iiop.IIOPSSLSocketFactory.createSocket(IIOPSSLSocketFactory.java:332) ... 15 more It's o.k. for now (while I'm still in development) that it bombs, but it does this repeatedly and the catch clause is never reached (even though I'm catching Throwable) - the message is not printed. So how can I handle connection errors during lookup in my program?

• Is it possible to keep mysql migration running without keeping connection open?

  - by taw

  ALTER TABLE can easily take a few days - and during this time there's a non-negligible chance of connection getting terminated due to network problems. Is it possible to start ALTER TABLE (or CREATE TABLE ... SELECT ...; or some other very long running query) and leave it running without keeping connection open all the time? (the obvious solution of screen + console mysql client won't easily work as there's no ssh running on that server, only mysqld).

• How can I emulate the ASP.NET Ajax UpdatePanel when using ASP.NET MVC?

  - by Gary McGill

  In "traditional" ASP.NET (Web Forms), the UpdatePanel control lets you do a partial refresh of a part of a page. You don't need to write much code to hook this up. What's the equivalent in ASP.NET MVC? I'm guessing I'd need to use a partial view for the bit that I want to update, then on the client side retrieve that HTML and pump it into the innerHtml of the correct DIV? A tutorial/example would be helpful...

• Tips for making administration of Drupal site easier

  - by Busk

  I'm creating a Drupal site for a client, and I'd like to make administrating the site as easy as possible for them.

But I was wondering if anyone has any other helpful tips. Thanks

  - by Jason Livesay

  Does anyone know where I can find the code for the carousel.us JavaScript 3D Carousel? Developer's site (http://www.piksite.com/carousel.us/) is down. I see it referenced all over in articles and tutorials but so far haven't been able to find the actual code to download except from that site which is just ads now. Client wants that specific thing and it doesn't make sense to code it from scratch. Thanks.

• xmlns='' was not expected when deserializing nested classes

  - by Mavrik

  I have a problem when attempting to serialize class on a server, send it to the client and deserialize is on the destination. On the server I have the following two classes: [XmlRoot("StatusUpdate")] public class GameStatusUpdate { public GameStatusUpdate() {} public GameStatusUpdate(Player[] players, Command command) { this.Players = players; this.Update = command; } [XmlArray("Players")] public Player[] Players { get; set; } [XmlElement("Command")] public Command Update { get; set; } } and [XmlRoot("Player")] public class Player { public Player() {} public Player(PlayerColors color) { Color = color; ... } [XmlAttribute("Color")] public PlayerColors Color { get; set; } [XmlAttribute("X")] public int X { get; set; } [XmlAttribute("Y")] public int Y { get; set; } } (The missing types are all enums). This generates the following XML on serialization: <?xml version="1.0" encoding="utf-16"?> <StatusUpdate> <Players> <Player Color="Cyan" X="67" Y="32" /> </Players> <Command>StartGame</Command> </StatusUpdate> On the client side, I'm attempting to deserialize that into following classes: [XmlRoot("StatusUpdate")] public class StatusUpdate { public StatusUpdate() { } [XmlArray("Players")] [XmlArrayItem("Player")] public PlayerInfo[] Players { get; set; } [XmlElement("Command")] public Command Update { get; set; } } and [XmlRoot("Player")] public class PlayerInfo { public PlayerInfo() { } [XmlAttribute("X")] public int X { get; set; } [XmlAttribute("Y")] public int Y { get; set; } [XmlAttribute("Color")] public PlayerColor Color { get; set; } } However, the deserializer throws an exception: There is an error in XML document (2, 2). <StatusUpdate xmlns=''> was not expected. What am I missing or doing wrong?

• How to set page expiry date in SharePoint

  - by deverop

  A client of mine needs the ability to expire pages on specific dates. When that date arrives, the page should be inaccessible (possibly switch to a non-published state) and should not appear in all menus. Any idea how to go about this?
