  • What is "with" used for in PHP?

    - by Jason
    I have come across this line in the eloquent ORM library: return with(new static)->newQuery(); I've never seen "with" used before, and cannot find it in the PHP documentation. I'm guessing "with" is a stop-word in most searches, so I am not even getting close. Never having encountered "with" in many years of programming PHP, I feel like I'm missing out. What does it do? I did come across one passing comment regarding the ORM, that mentioned "with" is no longer needed in PHP-5.4, but that was as much as was said.

  • How to determine bandwidth used by cron job?

    - by Lost_in_code
    I'm not a unix guy. CPanel does a good job of managing cronjobs and that is what I used to run dozens of cronjobs. All of them combined run more than 5000 times every day. Every cron makes a call to an external API. How can I check how much bandwidth are all the cron jobs eating? For my website I use awstats and that shows bandwidth usage et al. Another thing is that I dont want the admins to ban the cron jobs because they are using too much bandwidth (and CPU), more than what is allocated in my web hosting package.

  • QFileDialog used as widget

    - by lvp
    Hi! My goal is: user can choose file (only *mp3) and after clicking twice on it it should play (so the QString to file should be send to play() funtion) Firstly I started to work with QTreeView, but it has signal when the file is selected. So I decided to create QFileDialog and used it as widget built-in into MainWindow. The only problem that I have, that after double-click it dissapers. It is possible to avoid it? Should I work with some QDialog::finished() signal or, QDialog::done()?

  • Compiling a DLL which includes Ogre3D gives an assertion error when used

    - by samaursa
    Hi, I have a framework that I am building and is being compiled into a static library to be used by other projects. The library works perfectly without issues. The problem is that the link time is very long for the projects that use the library so I thought I will make a DLL project of the same framework. I started with baby steps and created an MFC DLL project through visual studio. The project has the following header: /// -------------------------------------------- #ifndef OGRECORE_H #define OGRECORE_H #ifdef OGREFW_EXPORT #define OGREFW_DLL __declspec(dllexport) #else #define OGREFW_DLL __declspec(dllimport) #endif class OgreRoot; namespace OgreFW { class OGREFW_DLL OgreCore// : public OIS::KeyListener, public OIS::MouseListener { public: OgreCore(); ~OgreCore(); }; }; #endif // OGRECORE_H and this is the source #include "stdafx.h" #include "OgreCore.h" //#include "Ogre.h" //#include "OgreRoot.h" //#include "OgreRenderWindow.h" //#include "OgreLog.h" //#include "OgreLogManager.h" //#include "OgreOverlay.h" //#include "OgreViewport.h" //#include "OgreRenderWindow.h" //#include "OgreFrameListener.h" //#include "OgreWindowEventUtilities.h" //#include "OgreSceneNode.h" //#include "OgreEntity.h" //#include "OgreManualObject.h" //#include "OgreMeshManager.h" //#include "OgreConfigFile.h" //#include "OgreOverlayContainer.h" //#include "OgreOverlayManager.h" namespace OgreFW { OGREFW_DLL OgreCore::OgreCore() { } // ------------------------ OGREFW_DLL OgreCore::~OgreCore() { } } As you can see I have commented out Ogre includes. When a project uses the compiled DLL and constructs this (OgreCore) class, it works perfectly fine. As soon as uncomment one of the Ogre includes and compile the DLL again, the project that uses the DLL now gives an assertion error. The full details can be found here in the Ogre forum post. I posted the question there first but since its not really an Ogre specific question I thought I will try here as well. The link to the Ogre post is: http://www.ogre3d.org/forums/viewtopic.php?f=2&t=58403 Thank you in advance

  • RegAsm for Class Library Used in VB6 Application

    - by michael.lukatchik
    To be short and to the point, I've built a C# class library that is both COM-Visible and Registered for COM Interop. I've compiled the library, which resulted in the generation of .dll and .tlb files. I have another machine that's running a VB6 application. So, I copied the .dll and .tlb files over to C:/Windows/system32 folder on the machine. I then registered those files using the following: C:\Windows\Microsoft.NET\Framework\v2.0.50727\RegAsm C:\Windows\system32\TestClass.dll /tlb:TestClass.tlb After the files were registered successfully, I added a project reference to the Test.tlb file from inside my VB6 app, then I tried to invoke a method in my new referenced class like so: Dim myObject As TestNamespace.TestClass Set myObject = New TestNamespace.TestClass MsgBox (myObject.TestMethod()) It doesn't work, and I receive a -2147024894 Automation Error. I've read that I shouldn't install the dll into a private folder like system32. I should either be registering in the GAC or I should be registering in another location using the "/codebase" option: C:\Windows\Microsoft.NET\Framework\v2.0.50727\RegAsm C:\TestClass.dll /tlb:TestClass.tlb /codebase Is there any reason I shouldn't be using system32? Past devs that have worked on this project have placed assembly files used by this VB6 project into system32 and there haven't seemed to be any issues. When I register my dll in the system32 location, I get the Automation Error. When I register my dll in another location (i.e. C:/), the method call into my class library from VB6 works as expected. What gives? I should mention that we will NOT be using the GAC to register any DLL's. That's just the way it is. Any help is appreciated. Mike

  • Can FluentNHibernate be used with .Net4?

    - by stiank81
    I have a WPF application running with .Net3.5 using FluentNHibernate, and all works fine. When I upgraded to VS2010 I ran into some odd problems, but after changing to use x64 variant of SQLite it worked fine again. Now I want to change to use .Net4, but this has turned into a more painful experience then I expected.. First I met a problem which required that I set a [SecurityCritical] attribute. Fine - I fixed this. But the reason this was exposed was because an exception was thrown in the first place. And the exception thrown was the following - when calling FluentConfiguration.BuildConfiguration: FluentConfigurationException unhandled An invalid or incomplete configuration was used while creating a SessionFactory. Check PotentialReasons collection, and InnerException for more detail The inner exception gives us more information: Message = "Could not create the driver from NHibernate.Driver.SQLite20Driver, NHibernate, Version=2.1.2.4000, Culture=neutral, PublicKeyToken=aa95f207798dfdb4." This is what I saw in my own project when moving to VS2010. I have tried changing Fluent to use the x64 variant of SQLite, but this doesn't change anything. Does it sound like it might be related to mixing of 32bit and 64bit assemblies? I see that there are also others that have seen this problem, but I haven't really seen any solution yet. Anyone out there using Fluent with .Net4 and SQLite - on a 64bit machine - successfully? Help! I'm lost...

  • XmlAttribute/XmlText cannot be used to encode complex type

    - by Conrad C
    I want to serialize a class Ticket into xml. I get the error :"XmlAttribute/XmlText cannot be used to encode complex type" because of my customfield class.

  • Count bits used in int

    - by sigvardsen
    If you have the binary number 10110 how can I get it to return 5? e.g a number that tells how many bits are used? There are some likewise examples listed below: 101 should return 3 000000011 should return 2 11100 should return 5 101010101 should return 9 How can this be obtained the easiest way in Java? I have come up with the following method but can i be done faster: public static int getBitLength(int value) { int l = 1; if (value >> 16 > 0) { value = value >> 16; l += 16; } if (value >> 8 > 0) { value = value >> 8; l += 8; } if (value >> 4 > 0) { value = value >> 4; l += 4; } if (value >> 2 > 0) { value = value >> 2; l += 2; } if (value >> 1 > 0) { value = value >> 1; l += 1; } return l; }

  • How to view shell commands used by eclipse "run configurations"

    - by gmale
    Given a "run configuration" in Eclipse, I want to print out the associated shell command that would be used to run it. For example: Right now, in Eclipse, if I click "play" it will run: mvn assembly:directory -Dmaven.test.skip=true I don't see that command, I just know that's what the IDE must run, at some point. However, some of the other run configurations are far more complex with long classpaths and virtual machine options and, frankly, sometimes I have no idea what the equivalent shell command would be (particularly when it comes to Flex). There must be some way to access the shell command that would be associated with a "Run Configuration" in Eclipse/Flex Builder. This information must be available, which leads me to believe someone has written a plugin to display it. Or maybe there's already an option built into Eclipse for accessing this. So is there a way to, essentially, convert an Eclipse run configuration into a shell command? (for context only: I'm asking because I'm writing a bash script that automates everything I do, during development--from populating the Database all the way to opening Firefox and clearing the cache before running the web app. So every command I run from the IDE needs to exist in the script. Some are tricky to figure out.)

  • Creating an appropriate index for a frequently used query in SQL Server

    - by Slauma
    In my application I have two queries which will be quite frequently used. The Where clauses of these queries are the following: WHERE FieldA = @P1 AND (FieldB = @P2 OR FieldC = @P2) and WHERE FieldA = @P1 AND FieldB = @P2 P1 and P2 are parameters entered in the UI or coming from external datasources. FieldA is an int and highly on-unique, means: only two, three, four different values in a table with say 20000 rows FieldB is a varchar(20) and is "almost" unique, there will be only very few rows where FieldB might have the same value FieldC is a varchar(15) and also highly distinct, but not as much as FieldB FieldA and FieldB together are unique (but do not form my primary key, which is a simple auto-incrementing identity column with a clustered index) I'm wondering now what's the best way to define an index to speed up specifically these two queries. Shall I define one index with... FieldB (or better FieldC here?) FieldC (or better FieldB here?) FieldA ... or better two indices: FieldB FieldA and FieldC FieldA Or are there even other and better options? What's the best way and why? Thank you for suggestions in advance!

  • How to find which delimiter was used during string split (VB.NET)

    - by typoknig
    Hi all, lets say I have a string that I want to split based on several characters, like ".", "!", and "?". How do I figure out which one of those characters split my string so I can add that same character back on to the end of the split segments in question? Dim linePunctuation as Integer = 0 Dim myString As String = "some text. with punctuation! in it?" For i = 1 To Len(myString) If Mid$(entireFile, i, 1) = "." Then linePunctuation += 1 Next For i = 1 To Len(myString) If Mid$(entireFile, i, 1) = "!" Then linePunctuation += 1 Next For i = 1 To Len(myString) If Mid$(entireFile, i, 1) = "?" Then linePunctuation += 1 Next Dim delimiters(3) As Char delimiters(0) = "." delimiters(1) = "!" delimiters(2) = "?" currentLineSplit = myString.Split(delimiters) Dim sentenceArray(linePunctuation) As String Dim count As Integer = 0 While linePunctuation > 0 sentenceArray(count) = currentLineSplit(count)'Here I want to add what ever delimiter was used to make the split back onto the string before it is stored in the array.' count += 1 linePunctuation -= 1 End While

  • How to efficiently resize an array of values, without boxing, used within a Dictionary<string, float[]>

    - by makerofthings7
    In the code below, Pages is defined as public SortedDictionary<DateTime, float[]> Pages { get; set; } I am trying to dynamically increase the size of this array. Can anyone tell how to increase the sized of the innermost float[]? var tt = currentContainer.Pages[dateTime]; Array.Resize<float>(ref tt, currentContainer.Pages.Count + 1); Fail 1 I tried the following code and get index out of range exception SortedDictionary<DateTime, float[]> Pages = new SortedDictionary<DateTime,float[]>(); float[] xx = new float[1]; xx[0] = 1; DateTime tempTime = DateTime.UtcNow; Pages.Add(tempTime, xx); var tt = Pages[tempTime]; Array.Resize<float>(ref tt, Pages.Count + 1); Pages[tempTime][1] = 2; Fail 2 The following gives a compile time error (property, index, or dynamic member can't be used as a ref value) SortedDictionary<DateTime, float[]> Pages = new SortedDictionary<DateTime,float[]>(); float[] xx = new float[1]; xx[0] = 1; DateTime tempTime = DateTime.UtcNow; Pages.Add(tempTime, xx); var tt = Pages[tempTime]; // The line below is different from Fail 1 above ... compile time error Array.Resize<float>(ref Pages[tempTime], Pages.Count + 1); Pages[tempTime][1] = 2; Question What is the most performant answer to resize this array? Would the answer change if it's likely that the final size will be 100-200 floats or 700-900 floats? What if I change my allocation size from +1 to +128? .. or larger?

  • What to call factory-like (java) methods used with immutable objects

    - by StaxMan
    When creating classes for "immutable objects" immutable meaning that state of instances can not be changed; all fields assigned in constructor) in Java (and similar languages), it is sometimes useful to still allow creation of modified instances. That is, using an instance as base, and creating a new instance that differs by just one property value; other values coming from the base instance. To give a simple example, one could have class like: public class Circle { final double x, y; // location final double radius; public Circle(double x, double y, double r) { this.x = x; this.y = y; this.r = r; } // method for creating a new instance, moved in x-axis by specified amount public Circle withOffset(double deltaX) { return new Circle(x+deltaX, y, radius); } } So: what should method "withOffset" be called? (note: NOT what its name ought to be -- but what is this class of methods called). Technically it is kind of a factory method, but somehow that does not seem quite right to me, since often factories are just given basic properties (and are either static methods, or are not members of the result type but factory type). So I am guessing there should be a better term for such methods. Since these methods can be used to implement "fluent interface", maybe they could be "fluent factory methods"? Better suggestions? EDIT: as suggested by one of answers, java.math.BigDecimal is a good example with its 'add', 'subtract' (etc) methods. Also: I noticed that there's this question (by Jon Skeet no less) that is sort of related (although it asks about specific name for method)

  • Spring MessageSource not being used during validation

    - by Jeremy
    I can't get my messages in messages.properties to be used during Spring validation of my form backing objects. app-config.xml: <bean id="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource"> <property name="basename" value="messages" /> </bean> WEB-INF/classes/messages.properties: NotEmpty=This field should not be empty. Form Backing Object: ... @NotEmpty @Size(min=6, max=25) private String password; ... When I loop through all errors in the BindingResult and output the ObjectError's toString I get this: Field error in object 'settingsForm' on field 'password': rejected value []; codes [NotEmpty.settingsForm.password,NotEmpty.password,NotEmpty.java.lang.String,NotEmpty]; arguments [org.springframework.context.support.DefaultMessageSourceResolvable: codes [settingsForm.password,password]; arguments []; default message [password]]; default message [may not be empty] As you can see the default message is "may not be empty" instead of my message "This field should not be empty". I do get my correct message if I inject the messageSource into a controller and output this: messageSource.getMessage("NotEmpty", new Object [] {"password"}, "default empty message", null); So why isn't the validation using my messages.properties? I'm running Spring 3.1.1. Thanks!

  • System.IO.IOException: file used by another process

    - by Srodriguez
    Dear all, I've been working in this small piece of code that seems trivial but still i cannot really see where is the problem. My functions does a pretty simple thing. Opens a file, copy its contents, replace a string inside and copy it back to the original file (a simple search and replace inside a text file then). I didn't really know how to do that as I'm adding lines to the original file, so i just create a copy of the file, (file.temp) copy also a backup (file.temp) then delete the original file(file) and copy the file.temp to file. I get an exception while doing the delete of the file. Here is the sample code: private static bool modifyFile(FileInfo file, string extractedMethod, string modifiedMethod) { Boolean result = false; FileStream fs = new FileStream(file.FullName + ".tmp", FileMode.Create, FileAccess.Write); StreamWriter sw = new StreamWriter(fs); StreamReader streamreader = file.OpenText(); String originalPath = file.FullName; string input = streamreader.ReadToEnd(); Console.WriteLine("input : {0}", input); String tempString = input.Replace(extractedMethod, modifiedMethod); Console.WriteLine("replaced String {0}", tempString); try { sw.Write(tempString); sw.Flush(); sw.Close(); sw.Dispose(); fs.Close(); fs.Dispose(); streamreader.Close(); streamreader.Dispose(); File.Copy(originalPath, originalPath + ".old", true); FileInfo newFile = new FileInfo(originalPath + ".tmp"); File.Delete(originalPath); File.Copy(fs., originalPath, true); result = true; } catch (Exception ex) { Console.WriteLine(ex); } return result; }` And the related exception System.IO.IOException: The process cannot access the file 'E:\mypath\myFile.cs' because it is being used by another process. at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath) at System.IO.File.Delete(String path) at callingMethod.modifyFile(FileInfo file, String extractedMethod, String modifiedMethod) Normally these errors come from unclosed file streams, but I've taken care of that. I guess I've forgotten an important step but cannot figure out where. Thank you very much for your help,

  • Can ASM method-visitors be used with interfaces?

    - by Olaf Mertens
    I need to write a tool that lists the classes that call methods of specified interfaces. It will be used as part of the build process of a large java application consisting of many modules. The goal is to automatically document the dependencies between certain java modules. I found several tools for dependency analysis, but they don't work on the method level, just for packages or jars. Finally I found ASM, that seems to do what I need. The following code prints the method dependencies of all class files in a given directory: import java.io.*; import java.util.*; import org.objectweb.asm.ClassReader; public class Test { public static void main(String[] args) throws Exception { File dir = new File(args[0]); List<File> classFiles = new LinkedList<File>(); findClassFiles(classFiles, dir); for (File classFile : classFiles) { InputStream input = new FileInputStream(classFile); new ClassReader(input).accept(new MyClassVisitor(), 0); input.close(); } } private static void findClassFiles(List<File> list, File dir) { for (File file : dir.listFiles()) { if (file.isDirectory()) { findClassFiles(list, file); } else if (file.getName().endsWith(".class")) { list.add(file); } } } } import org.objectweb.asm.MethodVisitor; import org.objectweb.asm.commons.EmptyVisitor; public class MyClassVisitor extends EmptyVisitor { private String className; @Override public void visit(int version, int access, String name, String signature, String superName, String[] interfaces) { this.className = name; } @Override public MethodVisitor visitMethod(int access, String name, String desc, String signature, String[] exceptions) { System.out.println(className + "." + name); return new MyMethodVisitor(); } } import org.objectweb.asm.commons.EmptyVisitor; public class MyMethodVisitor extends EmptyVisitor { @Override public void visitMethodInsn(int opcode, String owner, String name, String desc) { String key = owner + "." + name; System.out.println(" " + key); } } The Problem: The code works for regular classes only! If the class file contains an interface, visitMethod is called, but not visitMethodInsn. I don't get any info about the callers of interface methods. Any ideas?

  • Android - dialer icon gets placed in recently used apps after finish()

    - by Donal Rafferty
    In my application I detect the out going call when a call is dialled from the dialer or contacts. This works fine and I then pop up a dialog saying I have detected the call and then the user presses a button to close the dialog which calls finish() on that activity. It all works fine except that when I then hold the home key to bring up the recently used apps the dialer icon is there. And when it is clicked the dialog is brought back into focus in the foreground when the dialog activity should be dead and gone and not be able to be brought back to the foreground. Here is a picture of what I mean. So two questions arise, why would the dialer icon be getting placed there and why would it be recalling my activity to the foreground? Here is the code for that Activity which has a dialog theme: public class CallDialogActivity extends Activity{ boolean isRecording; AudioManager audio_service; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.dialog); audio_service = (AudioManager) getSystemService(Context.AUDIO_SERVICE); getWindow().addFlags(WindowManager.LayoutParams.FLAG_BLUR_BEHIND); Bundle b = this.getIntent().getExtras(); String number = b.getString("com.networks.NUMBER"); String name = b.getString("com.networks.NAME"); TextView tv = (TextView) findViewById(R.id.voip) ; tv.setText(name); Intent service = new Intent(CallAudio.CICERO_CALL_SERVICE); startService(service); final Button stop_Call_Button = (Button) findViewById(R.id.widget35); this.setVolumeControlStream(AudioManager.STREAM_VOICE_CALL); stop_Call_Button.setOnClickListener(new View.OnClickListener(){ public void onClick(View v){ Intent service = new Intent(CallAudio._CALL_SERVICE); //this is for Android 1.5 (sets speaker going for a few seconds before shutting down) stopService(service); Intent setIntent = new Intent(Intent.ACTION_MAIN); setIntent.addCategory(Intent.CATEGORY_HOME); setIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); startActivity(setIntent); finish(); isRecording = false; } }); final Button speaker_Button = (Button) findViewById(R.id.widget36); speaker_Button.setOnClickListener(new View.OnClickListener(){ public void onClick(View v){ if(true){ audio_service.setSpeakerphoneOn(false); } else{ audio_service.setSpeakerphoneOn(true); } } }); } @Override protected void onResume() { super.onResume(); } @Override protected void onPause() { super.onPause(); } public void onCofigurationChanged(Configuration newConfig) { super.onConfigurationChanged(newConfig); } } It calls a service that uses AudioRecord to record from the Mic and AudioTrack to play it out the earpiece, nothing in the service to do with the dialler. Has anyone any idea why this might be happening?

  • SSIS - user variable used in derived column transform is not available - in some cases

    - by soo
    Unfortunately I don't have a repro for my issue, but I thought I would try to describe it in case it sounds familiar to someone... I am using SSIS 2005, SP2. My package has a package-scope user variable - let's call it user_var first step in the control flow is an Execute SQL task which runs a stored procedure. All that SP does is insert a record in a SQL table (with an identity column) and then go back and get the max ID value. The Execute SQL task saves this output into user_var the control flow then has a Data Flow Task - it goes and gets some source data, has a derived column which sets a column called run_id to user_var - and saves the data to a SQL destination In most cases (this template is used for many packages, running every day) this all works great. All of the destination records created get set with a correct run_id. However, in some cases, there is a set of the destination data that does not get run_id equal to user_var, but instead gets a value of 0 (0 is the default value for user_var). I have 2 instances where this has happened, but I can't make it happen. In both cases, it was just less that 10,000 records that have run_id = 0. Since SSIS writes data out in 10,000 record blocks, this really makes me think that, for the first set of data written out, user_var was not yet set. Then, after that first block, for the rest of the data, run_id is set to a correct value. But control passed on to my data flow from the Execute SQL task - it would have seemed reasonable to me that it wouldn't go on until the SP has completed and user_var is set. Maybe it just runs the SP, but doesn't wait for it to complete? In both cases where this has happened there seemed to be a few packages hitting the table to get a new user_var at about the same time. And in both cases lots of data was written (40 million rows, 60 million rows) - my thinking is that that means the writes were happening for a while. Sorry to be both long-winded AND vague. A winning combination! Does this sound familiar to anyone? Thanks.

  • Project compilation requires a class that is not used anywhere

    - by Susei
    When I build with ant my project that uses libgdx, I get a strange error. It says that a class com.google.gwt.dom.client.ImageElement is not found, but it isn't used at all in the code. How can I find what makes this class necessary? Even searching over the whole project doesn't give any results. It says that error is at PixmapTextureAtlas.java:16 (class source), but there is no code that uses that ImageElement class. Adding the library containing com.google.gwt.dom.client.ImageElement class helps, of course, but I'd like to figure out why this class in needed. Here is the place in ant log that tells of the actual error: Compiling 3 source files to /home/suseika/Projects/tendiwa/client/bin /home/suseika/Projects/tendiwa/client/src/org/tendiwa/client/PixmapTextureAtlas.java:16: error: cannot access ImageElement class file for com.google.gwt.dom.client.ImageElement not found Here is the whole ant log: /usr/lib/jvm/java-7-oracle/bin/java -Xmx128m -Xss2m -Dant.home=/opt/intellijidea/lib/ant -Dant.library.dir=/opt/intellijidea/lib/ant/lib -Dfile.encoding=UTF-8 -classpath /opt/intellijidea/lib/ant/lib/ant-apache-regexp.jar:/opt/intellijidea/lib/ant/lib/ant-swing.jar:/opt/intellijidea/lib/ant/lib/ant-apache-xalan2.jar:/opt/intellijidea/lib/ant/lib/ant-jdepend.jar:/opt/intellijidea/lib/ant/lib/ant-apache-resolver.jar:/opt/intellijidea/lib/ant/lib/ant-jsch.jar:/opt/intellijidea/lib/ant/lib/ant.jar:/opt/intellijidea/lib/ant/lib/ant-testutil.jar:/opt/intellijidea/lib/ant/lib/ant-launcher.jar:/opt/intellijidea/lib/ant/lib/ant-apache-bsf.jar:/opt/intellijidea/lib/ant/lib/ant-commons-logging.jar:/opt/intellijidea/lib/ant/lib/ant-netrexx.jar:/opt/intellijidea/lib/ant/lib/ant-junit.jar:/opt/intellijidea/lib/ant/lib/ant-commons-net.jar:/opt/intellijidea/lib/ant/lib/ant-apache-bcel.jar:/opt/intellijidea/lib/ant/lib/ant-antlr.jar:/opt/intellijidea/lib/ant/lib/ant-apache-log4j.jar:/opt/intellijidea/lib/ant/lib/ant-jai.jar:/opt/intellijidea/lib/ant/lib/ant-apache-oro.jar:/opt/intellijidea/lib/ant/lib/ant-jmf.jar:/opt/intellijidea/lib/ant/lib/ant-javamail.jar:/usr/lib/jvm/java-7-oracle/lib/tools.jar:/opt/intellijidea/lib/idea_rt.jar com.intellij.rt.ant.execution.AntMain2 -logger com.intellij.rt.ant.execution.IdeaAntLogger2 -inputhandler com.intellij.rt.ant.execution.IdeaInputHandler -buildfile /home/suseika/Projects/tendiwa/client/build.xml jar build.xml property path description compile ant property property property description compile mkdir javac jar ant property description _core_src_available available ontology antcall property description _core_src_available available _build_core ant property property compile echo /home/suseika/Projects/tendiwa/client mkdir javac jar jar Building jar: /home/suseika/Projects/tendiwa/MainModule.jar description tempfile mkdir Created dir: /tmp/tendiwa373148820 unjar Expanding: /home/suseika/Projects/tendiwa/MainModule.jar into /tmp/tendiwa373148820 Expanding: /home/suseika/Projects/tendiwa/tendiwa-backend.jar into /tmp/tendiwa373148820 Expanding: /home/suseika/Projects/tendiwa/tendiwa-ontology.jar into /tmp/tendiwa373148820 copy Copying 1 file to /tmp/tendiwa373148820 java Created item short_sword Created item short_bow Created item bucket Created item boot Created item steel_morningstar Created item rifle_ammo Created item handAxe Created item iron_armor Created item steel_mace Created item jacket Created item fedora Created item wooden_arrow Saving sources to /tmp/tendiwa373148820/ontology/src tendiwa/resources/SoundTypes.java tendiwa/resources/CharacterTypes.java tendiwa/resources/ObjectTypes.java tendiwa/resources/FloorTypes.java tendiwa/resources/ItemTypes.java tendiwa/resources/MaterialTypes.java mkdir mkdir mkdir Created dir: /tmp/tendiwa373148820/ontology/bin javac jar Building jar: /home/suseika/Projects/tendiwa/tendiwa-ontology.jar echo Resources source code generated ant property property compile echo /home/suseika/Projects/tendiwa/client mkdir javac jar jar jar Building jar: /home/suseika/Projects/tendiwa/MainModule.jar mkdir javac /home/suseika/Projects/tendiwa/client/build.xml:25: Compile failed;

  • What Is .recently-used.xbel and How Do I Delete It for Good?

    - by The Geek
    If you’re reading this article, you’ve probably noticed the .recently-used.xbel file in the root of your User folder, and you’re wondering why it keeps constantly coming back even though you repeatedly delete it. So What Is It? The quick answer is that it’s part of the GTK+ library used by a number of cross-platform applications, perhaps the most well-known of which is the Pidgin instant messenger client. As the name implies, the file is used to store a list of the most recently used files. In the case of Pidgin, this comes into play when you are transferring files over IM, and that’s when the file will appear again. Note: this is actually a known and reported bug in Pidgin, but sadly the developers aren’t terribly responsive when it comes to annoyances. Pidgin seems to go for long periods of time without any updates, but we still use it because it’s open-source, cross-platform, and works well. How Do I Get Rid of It? Unfortunately, there’s no way to easily get rid of it, apart from using a different application. If you need to transfer files over Pidgin, the file is going to re-appear… but there’s a quick workaround! The general idea is to set the file properties to Hidden and Read-only. You’d think you could just set it to Hidden and be done with it, but Pidgin will re-create the file every time, so instead we’re leaving the file there and preventing it from being accessed. You could also totally remove access through the Security tab if you wanted to, but this worked fine for me… as you can see, no more file in the folder. Of course, you can’t have the show hidden files and folders option turned on, or the file will continue to show up. Want to get really geeky? You can toggle hidden files with a shortcut key.

  • Set the JAXB context factory initialization class to be used

    - by user1902288
    I have updated our projects (Java EE based running on Websphere 8.5) to use a new release of a company internal framework (and Ejb 3.x deployment descriptors rather than the 2.x ones). Since then my integration Tests fail with the following exception: [java.lang.ClassNotFoundException: com.ibm.xml.xlxp2.jaxb.JAXBContextFactory] I can build the application with the previous framework release and everything works fine. While debugging i noticed that within the ContextFinder (javax.xml.bind) there are two different behaviours: Previous Version (Everything works just fine): None of the different places brings up a factory class so the default factory class gets loaded which is com.sun.xml.internal.bind.v2.ContextFactory (defined as String constant within the class). Upgraded Version (ClassNotFound): There is a resource "META-INF/services/javax.xml.bind.JAXBContext" beeing loaded successfully and the first line read makes the ContextFinder attempt to load "com.ibm.xml.xlxp2.jaxb.JAXBContextFactory" which causes the error. I now have two questions: What sort is that resource? Because inside our EAR there is two WARs and none of those two contains a folder services in its META-INF directory. Where could that value be from otherwise? Because a filediff showed me no new or changed properties files. No need to say i am going to read all about the JAXB configuration possibilities but if you have first insights on what could have gone wrong or help me out with that resource (is it a real file i have to look for?) id appreciate a lot. Many Thanks! EDIT (according to comments Input/Questions): Out of curiosity, does your framework include JAXB JARs? Did the old version of your framework include jaxb.properties? Indeed (i am a bit surprised) the framework has a customized eclipselink-2.4.1-.jar inside the EAR that includes both a JAXB implementation and a jaxb.properties file that shows the following entry in both versions (the one that finds the factory as well as in the one that throws the exception): javax.xml.bind.context.factory=org.eclipse.persistence.jaxb.JAXBContextFactory I think this is has nothing to do with the current issue since the jar stayed exactly the same in both EARs (the one that runs/ the one with the expection) It's also not clear to me why the old version of the framework was ever selecting the com.sun implementation There is a class javax.xml.bind.ContextFinder which is responsible for initializing the JAXBContextFactory. This class searches various placess for the existance of a jaxb.properties file or a "javax.xml.bind.JAXBContext" resource. If ALL of those places dont show up which Context Factory to use there is a deault factory loaded which is hardcoded in the class itself: private static final String PLATFORM_DEFAULT_FACTORY_CLASS = "com.sun.xml.internal.bind.v2.ContextFactory"; Now back to my problem: Building with the previous version of the framework (and EJB 2.x deployment descriptors) everything works fine). While debugging i can see that there is no configuration found and thatfore above mentioned default factory is loaded. Building with the new version of the framework (and EJB 3.x deployment descriptors so i can deploy) ONLY A TESTCASE fails but the rest of the functionality works (like i can send requests to our webservice and they dont trigger any errors). While debugging i can see that there is a configuration found. This resource is named "META-INF/services/javax.xml.bind.JAXBContext". Here are the most important lines of how this resource leads to the attempt to load 'com.ibm.xml.xlxp2.jaxb.JAXBContextFactory' which then throws the ClassNotFoundException. This is simplified source of the mentioned javax.xml.bind.ContextFinder class: URL resourceURL = ClassLoader.getSystemResource("META-INF/services/javax.xml.bind.JAXBContext"); BufferedReader r = new BufferedReader(new InputStreamReader(resourceURL.openStream(), "UTF-8")); String factoryClassName = r.readLine().trim(); The field factoryClassName now has the value 'com.ibm.xml.xlxp2.jaxb.JAXBContextFactory' (The day i understand how to format source code on stackoverflow will be my biggest step ahead.... sorry for the formatting after 20 mins it still looks the same :() Because this has become a super lager question i will also add a bounty :)
