  • [grails + xfire] How to handle errors in SOAP services?

    - by Mulone
    Hi all, I'm implementing a web service on the xfire plugin. I was wondering how I'm supposed to handle the errors. I tried with this setup but the error is not returned to the SOAP client: GaSession[] myMethod( String userId ) throws MyException{ GaUser user = GaUser.findByUserId( userId ) if (!user) throw new MyException("user ${userId} does not exist") // do stuff and return valid results } Is there a standard way to handle errors and return them to the client in a clear way? My log is full of messages like: 2010-06-13 18:20:40,926 [Thread-289] DEBUG aegis.XMLClassMetaInfoManager - Mapping file : /com/mycompany/MyClass.aegis.xml not found. Is there a way to fix this? Cheers!

  • Likelihood of IOError during print vs. write

    - by jkasnicki
    I recently encountered an IOError writing to a file on NFS. There wasn't a disk space or permission issue, so I assume this was just a network hiccup. The obvious solution is to wrap the write in a try-except, but I was curious whether the implementation of print and write in Python make either of the following more or less likely to raise IOError: f_print = open('print.txt', 'w') print >>f_print, 'test_print' f_print.close() vs. f_write = open('write.txt', 'w') f_write.write('test_write\n') f_write.close() (If it matters, specifically in Python 2.4 on Linux).

  • ListView exception for Images + Text

    - by drozzy
    I am trying to create a simple Icon+Text ListView but it does not work. I am using 2.1 Android SDK. My main class is very small slightly modified from the tutorial: public class Stuffs extends ListActivity { static final String[] COUNTRIES = new String[] {"A", "B","C"}; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setListAdapter(new ArrayAdapter<String>(this, R.layout.list_item, R.id.title, COUNTRIES)); } } and my list_item.xml file is this: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content" android:orientation = "horizontal"> <ImageView android:id = "@+id/icon" android:src="@drawable/icon" /> <TextView android:id = "@+id/title" android:padding="10dp" android:textSize="16sp" > </TextView> </LinearLayout> I have also created a "drawable" directory in my res directory and copied a "icon.png" into it. But any time I try to run this the application hangs up unexpected in my android emulator. Am I missing something?

  • What happens on a JMS queue when onMessage() throws a JMSException?

    - by user311121
    Hi, I'm using Spring 2.5 with my custom class that implements MessageListener. If a JmsException is thrown in my onMessage( ) method, what happens to the state of the queue? Is the message considered "delivered" by the queue the moment onMessage is called? Or does the JmsException trigger some kind of rollback and the message is re-entered on the queue? Thanks in advance!

  • Null pointer exception on .iterator() call

    - by Peter
    I'm getting a strange NullPointerException, evidently thrown by the following line of code: Iterator<Note> it = notes.iterator(); I've checked, and at the time the java.util.TreeSet notes is always non-null (with 15 elements). The TreeSet API says nothing about iterator() throwing NullPointerExceptions. What else could be going here?

  • Error : The Type Initializer of Daemon.Global threw an exception in c#

    - by srk
    I am using the below class file, where some variables are declared to use in the entire application. Now I used that variable BlockLogOut in another class file to make the value true. I just put this below line and getting error in it.. TypeInitializationException Global.BlockLogOut = True; The weird thing is, it was working fine for many months and i am getting this error now on the above line. Of course i was modifying some other stuffs in the application, but surely not this class file. What would have been the problem? namespace Daemon { class Global { public static bool BlockLogOut = false; } }

  • MySQL transaction conundrum

    - by David Faitelson
    I need to perform several inserts in a single atomic transaction. For example: start transaction; insert ... insert ... commit; However when MySQL encounters an error it aborts only the particular statement that caused the error. For example, if there is an error in the second insert statement the commit will still take place and the first insert statement will be recorded. Thus, when errors occur a MySQL transaction is not really a transaction. To overcome this problem I have used an error exit handler where I rollback the transaction. Now the transaction is silently aborted but I don't know what was the problem. So here is the conundrum for you: How can I both make MySQL abort a transaction when it encounters an error, and pass the error code on to the caller?

  • Python raises a KeyError (for an out of dictionary key) even though the key IS in the dictionary

    - by ignorantslut
    I'm getting a KeyError for an out of dictionary key, even though I know the key IS in fact in the dictionary. Any ideas as to what might be causing this? print G.keys() returns the following: ['24', '25', '20', '21', '22', '23', '1', '3', '2', '5', '4', '7', '6', '9', '8', '11', '10', '13', '12', '15', '14', '17', '16', '19', '18'] but when I try to access a value in the dictionary on the next line of code... for w in G[v]: #note that in this example, v = 17 I get the following error message: KeyError: 17 Any help, tips, or advice are all appreciated. Thanks.

  • jUnit same exception in different cases

    - by coubeatczech
    Hi, I'm writing a jUnit test for a constructor that parses a String and then check numerous things. When there's wrong data, for every thing, some IllegalArgumentException with different message is thrown. So I would like to write tests for it, but how can i recognize what error was thrown? This is how can I do it: @Test(expected=IllegalArgumentException.class) public void testRodneCisloRok(){ new RodneCislo("891415",dopocitej("891415")); } and this is how I would like to be, but I don't know if it is possible to write it somehow: @Test(expected=IllegalArgumentException.class("error1")) public void testRodneCisloRok(){ new RodneCislo("891415",dopocitej("891415")); }

  • Which of the two exceptions was called?

    - by Rob
    If I have a routine that can throw an ArgumentException in two places, something like... if (Var1 == null) { throw new ArgumentException ("Var1 is null, this cannot be!"); } if (Val2 == null) { throw new ArgumentException ("Var2 is null, this cannot be either!"); } What’s the best way of determining in my calling procedure which of the two exceptions was thrown? Or Am I doing this in the wrong fashion?

  • What's the best practice in case something goes wrong in Perl code?

    - by Geo
    I saw code which works like this: do_something($param) || warn "something went wrong\n"; and I also saw code like this: eval { do_something_else($param); }; if($@) { warn "something went wrong\n"; } Should I use eval/die in all my subroutines? Should I write all my code based on stuff returned from subroutines? Isn't eval'ing the code ( over and over ) gonna slow me down?
