  • log4net - getting appenders specific to only one logger

    - by andreav
    I'm looking for a way to get all appenders attached to one logger instance. I tried: Hierarchy hierarchy = LogManager.GetRepository() as Hierarchy; hierarchy.GetAppenders() as per documentation this returns all appenders for all loggers currently configured. When I try this: LogManager.GetLogger("MyLoggerName").Logger.Repository.GetAppenders(); I get the same result. I would like to retrieve only appenders attached to one logger ("MyLoggerName" in this case) Were am i wrong? Thank you.

  • Java Null Pointer Exception :-(

    - by John-Michael Reed
    I've got a Null Pointer Exception in my main that just won't go away and I'm totally out of ideas. The error is on the line "Board[x][y].color = 2;" in which Board is a public, static array of piece objects that contain instance variables like the one "color" that is being set to 2 in the above statement. Pieces is not static - that is there are many different copies of pieces, each with its own data, but only one board. The array has been initialized and defined as both public Piece[][] Board = new Piece[8][8] and public static Piece[][] Board = new Piece[8][8], but no matter how I mess around with it (getting rid of static, putting the variable in another object, etc.), I can't seem to get the error to go away. Help?

  • how do you find the exact variable of a null pointer exception

    - by OVERTONE
    I've been at this one for a bit now. I've got a null pointer exception so im guessing somethings not been initialized. AdminMessages.inbox1.setText(messageRsetArray[0]); thats my code where its targetting. but i cant find what inside it hasnt been initiazed. AdminMessages is a class which contains a JTextField called inbox1, messageRsetArray is an array which has taken variables from an array. also inbox1 is static. i coulndt get the getters and setter to work. i know its bad practice though.

  • Best tool for monitoring Coldfusion interoperability with .Net web service

    - by John Galt
    Is there a tool to see the message sent to webservice hosted on an IIS server? I have a webservice written in .Net and our ColdFusion people are having trouble building a "complex" parameter. This problem is described from a ColdFusion perspective at: adobe forum question It runs when called from a .net client. While hosted on a server inside our LAN, I put it out on a public server so the WSDL could be viewed: please take a quick look at this WSDL here When the CF developer runs her code, she gets: java.lang.IllegalArgumentException: argument type mismatch ...and I am wondering if there is a tool I could run on the server that hosts my webservice to see if it is even entering the WS or is being rejected by Java code that CF uses and is not really even getting to my webservice.

  • iPhone/iPad fatal error in C++ code produces no output in the log

    - by morgancodes
    I'm trying to move away from Objective-C to C++ for audio in my iPad programming, due to the a few reports I've heard of Objective-C selectors sometimes causing audio glitches. So I'm starting to use pure C++ files. When a fatal error happens in one of the C++ files, I get no output from the log. The app just crashes. For example, if I do this in my C++ file: env = new ADSR(); cout << "setting env to null\n"; env = NULL; env->setSustainLevel(1); cout << "called function on non-initialized env\n"; I get the following output: setting env to null After that, there's a method called on NULL, which apparently kills the app, but absolutely nothing to that effect is reported. What do I need to do to have useful information logged when there's an error in my C++ code?

  • sysklogd ignores my log facilities

    - by Synther Lawrence
    I'm using sysklogd 1.5.5. All I want is to get local0 entries in /var/log/vr file. My conf: *.*;local0.none /var/log/messages local0.* /var/log/vr When I do logger -p local0.info "local0 test from logger" the message appear in /var/log/vr file. That's ok. But the following sends message to /var/log/messages instead of /var/log/vr: #include <stdlib.h> #include <syslog.h> int main(int argc, char const* argv[]) { openlog(NULL, LOG_PID, LOG_LOCAL0); syslog(LOG_INFO, "local0 test from app\n"); closelog(); return 0; } Where am I wrong?

  • Mac OS X: getting names of changed/written files

    - by Patrick
    I remember having a command line tool on an older Mac OS X version (Tiger?) that told me the name of every file that was written to (or read) by any process on the system. It used fseventd (? or something like that). Is there something like that for the newest Mac OS X (10.6)? It should be run in a terminal window and then I can use the system as normal. Let's say I type cat /etc/passwd, the output of that program would be similar to /bin/cat /etc/passwd I can't use lsof because I can't get the timing right. Is this clear or do you need more information?

  • appengine log console extremely slow

    - by Joey
    I am using the python app engine and finding that the log console on the local development server is terribly slow. Output to this window seems to show in chunks of about 5-15 lines every second. Is that typical? I find that it's so slow that it hinders my debugging time waiting for log data to appear.

  • How to use the Zend_Log instance that was created using the Zend_Application_Resource_Log in a model

    - by Alex
    Our Zend_Log is initialized by only adding the following lines to application.ini resources.log.stream.writerName = "Stream" resources.log.stream.writerParams.mode = "a" So Zend_Application_Resource_Log will create the instance for us. We are already able to access this instance in controllers via the following: public function getLog() { $bootstrap = $this->getInvokeArg('bootstrap'); //if (is_null($bootstrap)) return false; if (!$bootstrap->hasPluginResource('Log')) { return false; } $log = $bootstrap->getResource('Log'); return $log; } So far, so good. Now we want to use the same log instance in model classes, where we can not access the bootstrap. Our first idea was to register the very same Log instance in Zend_Registry to be able to use Zend_Registry::get('Zend_Log') everywhere we want: in our Bootstrap class: protected function _initLog() { if (!$this->hasPluginResource('Log')) { throw new Zend_Exception('Log not enabled'); } $log = $this->getResource('Log'); assert( $log != null); Zend_Registry::set('Zend_Log', $log); } Unfortunately this assertion fails == $log IS NULL --- but why?? It is clear that we could just initialize the Zend_Log manually during bootstrapping without using the automatism of Zend_Application_Resource_Log, so this kind of answers will not be accepted.

  • Managing a log stream in C++ in a cout-like notation

    - by Andry
    Hello! I have a class in c++ in order to write log files for an application of mine. I have already built the class and it works, it is something like this: class Logger { std::string _filename; public: void print(std::string tobeprinted); } Well, it is intuitive that, in order to print a line in the log file, for an object of Logger, it is simply necessary to do the following: Logger mylogger("myfile.log"); mylogger.print(std::string("This is a log line")); Well. Using a method approach is not the same as using a much better pattern like << is. I would like to do the following: Logger mylogger("myfile.log"); mylogger << "This is a log line"; That's all. I suppose I must overload the << operator... But overloading using this signature (the classic one): ostream& operator<<(ostream& output, const MyObj& o); But I do not have a ostream... So, should I do as follows? Logger& operator<<(Logger& output, const std::string& o); Is this the right way? Thanks

  • Java Custom exception throw behaves differently between different Projects

    - by Pablo
    I am attempting to call the following in my code: public void checkParticleLightRestriction(Particle parent) throws LightException { if ( parent == null ) { throw new LightException("quantum-particle-restrict.23", this); } In one Project the exception is thrown and the effect is similar to calling "return" whereby I am returned back to the point immediately succeeding where this method was called. However in another Project I get thrown completed out of the current package and to a point way prior to the point preceeding this method. It likes instead of being kicked out of a bar I am being deported all the way out of the country. My option are the wrap the throw in a try / catch but I am wondering why this difference in behaviour beween the 2 projects ?

  • Deactivate any calls to Log before publishing: are there tools to do this?

    - by Nicolas Raoul
    According to Google, I must "Deactivate any calls to Log methods in the source code" before publishing my Android app (section 4 of the publication checklist). My open-source project is large and it is a pain to do it manually every time I release. Additionally, removing a Log line is potentially tricky, for instance: if(condition) Log.d(LOG_TAG, "Something"); data.load(); data.show(); If I comment the Log line, then the condition applies to the next line, and chances are load() is not called. Are such situations rare enough that I can decide it should exist? This is on the official checklist, so I guess many people do this on a regular basis. So, is there a tool that removes all Log lines? Preferably one that is not tricked by code like the above.

  • null pointer exception on list.add

    - by Eric
    I've been working on this one error for a few hours so I thought I'd pick the brains of some pros. I am getting a null pointer exception at the modelData.add(i, es) method. I know from debugging that es isn't null. I'm really confused, thanks. public class EventTableModel extends AbstractTableModel { //private int rowCount = 0; protected List<EventSeat> modelData; private static final int COLUMN_COUNT = 3; private Event e; Event j = GUIpos.m; int i = 1; public EventTableModel(Event e) { this.e = e; try { System.out.println(modelData); for (EventSeat es : e.getEventSeats()) { modelData.add(i, es); i++; } } catch (DataException ex) { Logger.getLogger(EventTableModel.class.getName()).log(Level.SEVERE, null, ex); } }

  • CMD Execption Handling C/C++

    - by ciyo
    I will use some CMD commands in my program and these commands might throw some exceptions. And as you know, when an exception accours, CMD writes its own error message the screen. But, I want to write my own error message. My question is this: Is there a way to block CMD messages and write only my own error messages? P.S. This is not a complex program. It executes CMD commands using System(). Example: Let's say, the user can rename and copy any files in the program. As you know, if the user does not enter file's path properly, an error message is showed on the screen. And I want that this error message never appears on the screen. Only my own error message is showed. Thank you!

  • Adding Timestamp to Java's GC messages in Tomcat 6

    - by ripper234
    I turned on Java's GC log options -XX:+PrintGC -XX:+PrintGCTimeStamps -XX:+PrintGCDetails Which print out these messages to standard output (catalina.out): 314.884: [CMS-concurrent-mark-start] 315.014: [CMS-concurrent-mark: 0.129/0.129 secs] [Times: user=0.14 sys=0.00, real=0.13 secs] 315.014: [CMS-concurrent-preclean-start] 315.016: [CMS-concurrent-preclean: 0.003/0.003 secs] [Times: user=0.00 sys=0.00, real=0.00 secs] 315.016: [CMS-concurrent-abortable-preclean-start] 332.055: [GC 332.055: [ParNew: 17128K->84K(19136K), 0.0017700 secs] 88000K->70956K(522176K) icms_dc=4 , 0.0018660 secs] [Times: user=0.00 sys=0.00, real=0.00 secs] CMS: abort preclean due to time 352.253: [CMS-concurrent-abortable-preclean: 0.023/37.237 secs] [Times: user=0.78 sys=0.02, real=37.23 secs] How can I make these log lines appear with an actual timestamp (including date) instead of these numbers, which presumably mean "time since JVM started" ?

  • SQL Server 2008 error message from store procedure

    Hello everyone, When we met with such error message from store procedure, Message 1205, Level 13, State 52, the process Pr_FooV2, Line 9 Services (Process ID 111) and another process is deadlock in the lock | communication buffer resources, and has been chosen as the deadlock victim. Rerun the transaction. I am wondering whether such messages are stored in log files? I searched log folder of my SQL Server 2008 installation root (in my environment, it is C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\Log), but can not find such files. thanks in avdance, George

  • Tools for viewing logs of unlimited size

    - by jkff
    It's no secret that application logs can go well beyond the limits of naive log viewers, and the desired viewer functionality (say, filtering the log based on a condition, or highlighting particular message types, or splitting it into sublogs based on a field value, or merging several logs based on a time axis, or bookmarking etc.) is beyond the abilities of large-file text viewers. I wonder: Whether decent specialized applications exist (I haven't found any) What functionality might one expect from such an application? (I'm asking because my student is writing such an application, and the functionality above has already been implemented to a certain extent of usability)

  • ADO.NET DataService Exception

    - by Ravi
    Hi, I am working on C#.Net with ADO.NET Dataservice. I try to update one record to relational tabel, when I reach context.SetLink() I am getting exception("The context is not currently tracking the entity"). I don't know how to solve this problem. My code is specified below. LogNote dbLogNote =logNote; LogSubSession dbLogSubSession = (from p in context.LogSubSession where p.UID == logNote.SubSessionId select p).First<LogSubSession>() as LogSubSession; context.AddToLogNote(dbLogNote); dbLogNote.LogSubSession = dbLogSubSession; context.SetLink(dbLogNote, "LogSubSession", dbLogSubSession); context.SaveChanges(); Here LogSubSession is a primary table and LogNote is a foreign table. I am updating data into foreign table based on primary key table. Thanks

  • When to use try/catch

    - by coffeeaddict
    I'm always finding myself wanting to put a try/catch around the lets say Business Layer methods. But I feel though that I don't need a try/catch if I'm simply rethrowing it up to the Presentation Layer. Is that right? I should not be rethrowing an exception from code that's wrapped in a try/catch in a BL method and should be letting the caller which would be from the Presentation Layer code be using a try/catch to handle it there? The BL method will throw an error without the try/catch anyway..the compiler will. So it wouldn't make sense to use a try/catch in a BL method that's to be consumed by a layer higher up correct?

  • Is there a way to force JUnit to fail on ANY unchecked exception, even if swallowed

    - by Uri
    I am using JUnit to write some higher level tests for legacy code that does not have unit tests. Much of this code "swallows" a variety of unchecked exceptions like NullPointerExceptions (e.g., by just printing stack trace and returning null). Therefore the unit test can pass even through there is a cascade of disasters at various points in the lower level code. Is there any way to have a test fail on the first unchecked exception even if they are swallowed? The only alternative I can think of is to write a custom JUnit wrapper that redirects System.err and then analyzes the output for exceptions.
