  • RuntimeException: Could not start Selenium session: Internal Server Error

    - by user79685
    I am trying to detect a midair collision problem (simultaneous editin) using selenium. So I start a selenium session A with following (Super Class) selenium = new MASSelenium(serverHost, serverPort, *iexplore, browserURL); selenium.start(); selenium.open("index.cgi"); then I try starting a different selenium session B pointing to a different browser from the superclass (Sub Class): selenium2 = new MASSelenium(getServerHost(), getServerPort(), *firefox, getBrowserURL()); selenium2.start(); selenium2.open("index.cgi"); It works fine on my local machine (behaves as expected) but then when i run this same test on a remote machine (using bamboo build tool), i get this exception: java.lang.RuntimeException: Could not start Selenium session: Internal Server Error at com.thoughtworks.selenium.DefaultSelenium.start(DefaultSelenium.java:89) at gov.baba.arc.mas.selenium.tests.SimultaneousEditingConflictDetected.setUp(SimultaneousEditingConflictDetected.java:78) Caused by: com.thoughtworks.selenium.SeleniumException: Internal Server Error at com.thoughtworks.selenium.HttpCommandProcessor.throwAssertionFailureExceptionOrError(HttpCommandProcessor.java:97) at com.thoughtworks.selenium.HttpCommandProcessor.getCommandResponseAsString(HttpCommandProcessor.java:168) at com.thoughtworks.selenium.HttpCommandProcessor.executeCommandOnServlet(HttpCommandProcessor.java:104) at com.thoughtworks.selenium.HttpCommandProcessor.doCommand(HttpCommandProcessor.java:86) Any idea why this is happening?

  • Trying to add AddThis to multiple items through JavaScript

    - by Mantorok
    I have to add an AddThis chunk to a bunch of controls, the reason I'm doing this through JS is because the addthis: attributes cause XHTML validation errors, so I wrote a JS script that takes the control I want to add the html into and some other bits: function AddExternalLinks(control, url, title) { $(control).html("<div class'addthis_toolbox addthis_default_style'><a class='addthis_button_facebook'" + " addthis:url=" + url + " addthis:title=" + title + " addthis:description=" + title + "></a>" + "<a class='addthis_button_twitter' " + " addthis:url=" + url + " addthis:title=" + title + " addthis:description=" + title + "></a></div>" + "<script type='text/javascript' src='http://s7.addthis.com/js/250/addthis_widget.js#username=cornwallweb'></script>"); However this does not work, the html is added fine but the script fails with the following error: *c._Queuer is not a constructor [Break on this error] if(!window._ate){var _atd="www.addthis...(c) 2008, 2009, 2010 Add This, LLC / addthi...wallweb (line 2) Any ideas?

  • Java MVC - How to divide a done text game into MVC?

    - by Zopyrus
    Been sitting here for hours now trying to figure this out, so a bit sympathy for this large question. :) The Goal: I simply want to divide my done code into MVC (Model View Controller) parts. I have the game logics done and text based - the code works fine. The Problem: Well, I want to implement this code into MVC, but where do explain for the MODEL that it should use text-based? Because the VIEW is only for the layout (graphically) correct? I am having a REALLY hard time figuring out where to begin at all. Any pointers would be so nice! Here is my game logics code: import mind.*; import javax.swing.*; import java.util.*; import java.lang.*; import java.awt.*; public class Drive { String[] mellan; boolean gameEnd, checkempty, checkempty2, enemy, enemy2; String gr,rd,tom; int digits; public Drive() { // Gamepieces in textform gr="G"; rd="R"; tom=" "; mellan = new String[7]; String[] begin = {gr,gr,gr,tom,rd,rd,rd}; String[] end = {rd,rd,rd,tom,gr,gr,gr}; //input Scanner in = new Scanner(System.in); mellan=begin; gameEnd=false; while (gameEnd == false) { for(int i=0; i<mellan.length; i++) { System.out.print(mellan[i]); } System.out.print(" Choose 0-6: "); digits = in.nextInt(); move(); checkWin(); } } void move() { //BOOLEAN for gameruls!!! checkempty = digits<6 && mellan[digits+1]==tom; checkempty2 = digits>0 && mellan[digits-1]==tom; enemy = (mellan[digits]==gr && mellan[digits+1]==rd && mellan[digits+2]==tom); enemy2 = (mellan[digits]==rd && mellan[digits-1]==gr && mellan[digits-2]==tom); if(checkempty) { mellan[digits+1]=mellan[digits]; mellan[digits]=tom; } else if (checkempty2) { mellan[digits-1]=mellan[digits]; mellan[digits]=tom; } else if (enemy) { mellan[digits+2]=mellan[digits]; mellan[digits]=tom; } else if (enemy2) { mellan[digits-2]=mellan[digits]; mellan[digits]=tom; } } void checkWin() { String[] end = {rd,rd,rd,tom,gr,gr,gr}; for (int i=0; i<mellan.length; i++){ } if (Arrays.equals(mellan,end)) { for (int j=0; j<mellan.length; j++) { System.out.print(mellan[j]); } displayWin(); } } void displayWin() { gameEnd = true; System.out.println("\nNicely Done!"); return; } // Kör Drive! public static void main(String args[]) { new Drive(); } } Here is how I defined my DriveView thus far: (just trying to make one button to work) import mind.*; import javax.swing.*; import java.util.*; import java.lang.*; import java.awt.*; import java.awt.event.*; public class DriveView extends JFrame { JButton ruta1 = new JButton("Green"); JButton ruta2 = new JButton("Green"); JButton rutatom = new JButton(""); JButton ruta6 = new JButton("Red"); private DriveModel m_model; public DriveView(DriveModel model) { m_model = model; //Layout for View JPanel myPanel = new JPanel(); myPanel.setLayout(new FlowLayout()); myPanel.add(ruta1); myPanel.add(ruta2); myPanel.add(rutatom); myPanel.add(ruta6); this.setContentPane(myPanel); this.pack(); this.setTitle("Drive"); this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); } void addMouseListener(ActionListener mol) { ruta2.addActionListener(mol); } } And DriveController which gives me error at compile import mind.*; import java.awt.*; import java.awt.event.*; import javax.swing.*; import java.lang.*; public class DriveController { private DriveModel m_model; private DriveView m_view; public DriveController(DriveModel model, DriveView view) { m_model = model; m_view = view; view.addMouseListener(new MouseListener()); } class MouseListener implements ActionListener { public void actionPerformed(ActionEvent e) { String mening; mening = e.getActionCommand(); if (mening.equals("Green")) { setForeground(Color.red); } } } }

  • transform:translateX vs transition on left property. Which has better performance? CSS

    - by JackMahoney
    I'm making a slide out menu with HTML and CSS3 - especially transitions. I would like to know what is best practice / best performance to slide a relatively positioned div horizontally. When i click a button it adds a class to my div. Which class is better? (Note I can add all the browser prefixes later and this site only targets modern browsers). //option 1 .animate{ -webkit-transition:all ease 0.3s; -webkit-transform:translateZ(200px); } //option 2 .animate{ -webkit-transition:all ease 0.3s; left:200px; } Thanks

  • Django + Postgres: How to specify sequence for a field

    - by Giovanni Di Milia
    I have this model in django: class JournalsGeneral(models.Model): jid = models.AutoField(primary_key=True) code = models.CharField("Code", max_length=50) name = models.CharField("Name", max_length=2000) url = models.URLField("Journal Web Site", max_length=2000, blank=True) online = models.BooleanField("Online?") active = models.BooleanField("Active?") class Meta: db_table = u'journals_general' verbose_name = "Journal General" ordering = ['code'] def __unicode__(self): return self.name My problem is that in the DB (Postgres) the name of the sequence connected to jid is not journals_general_jid_seq as expected by Django but it has a different name. Is there a way to specify which sequence Django has to use for an AutoField? In the documentation I read I was not able to find an answer.

  • How to Uncheck A radio button

    - by user281867
    Hi, I have two forms, one with a radio button that users must select to edit.

  • Should Java IOException have been an unchecked RuntimeException?

    - by Derek Mahar
    Do you agree that the designers of Java class java.io.IOException should have made it an unchecked run-time exception derived from java.lang.RuntimeException instead of a checked exception derived only from java.lang.Exception? I think that class IOException should have been an unchecked exception because there is little that an application can do to resolve problems like file system errors. However, in When You Can't Throw An Exception, Elliotte Rusty Harold claims that most I/O errors are transient and so you can retry an I/O operation several times before giving up: For instance, an IOComparator might not take an I/O error lying down, but — because many I/O problems are transient — you can retry a few times, as shown in Listing 7: Is this generally the case? Can a Java application correct I/O errors or wait for the system to recover? If so, then it is reasonable for IOException to be checked, but if it is not the case, then IOException should be unchecked so that business logic can delegate handling this exception to a separate system error handler.

  • Grafting Scala 2.8 into a Netbeans NBAndroid Project...What steps am I missing?

    - by Michael Kohout
    Hi All; Due to Apple's recent T+C hijinks, I've become interested in developing for Android. Anyways, I'm trying to get a mixed-language Android 2.1 project going in Netbeans 6.8 (with the NBAndroid 0.10 plugin). The two languages being Java and Scala(2.8 head build). To give you a basic idea of what the app does right now, it's just a simple "Hello World" app. To get this to build, I've modified the projects's build.xml file: -- -injars ${scala-library}(!META-INF/MANIFEST.MF,!library.properties) -outjars "${build.classes.dir}/classes.min.jar" -libraryjars "${file.reference.android.jar}" -dontwarn -dontoptimize -dontobfuscate -keep public class * extends android.app.Activity -keep public class scala.xml.include.sax.Main** I've gotten the project so that it'll build, but it errors on startup in my Android Emulator(inside the emulator Android tells me my application has stopped unexpectedly). So my questions are: Does anyone see what I may be doing wrong? And is there any way to get access to the logs that the emulator must create? thanks Mike Kohout

  • request parameter is taking null value in servlets

    - by Dusk
    Hi, I want to know how can I get the value of the request parameters "j_username" and "j_password"? After successfully login using form based authentication, I want my servlet to get the value of parameters "j_username" and "j_password", but I'm getting null as the value in both parameters. Could anyone please tell me how can I get the actual value of both paramters?

  • RSpec mocking a nested model in Rails - ActionController problem

    - by emson
    Hi All I am having a problem in RSpec when my mock object is asked for a URL by the ActionController. The URL is a Mock one and not a correct resource URL. I am running RSpec 1.3.0 and Rails 2.3.5 Basically I have two models. Where a subject has many notes. class Subject < ActiveRecord::Base validates_presence_of :title has_many :notes end class Note < ActiveRecord::Base validates_presence_of :title belongs_to :subject end My routes.rb file nests these two resources as such: ActionController::Routing::Routes.draw do |map| map.resources :subjects, :has_many => :notes end The NotesController.rb file looks like this: class NotesController < ApplicationController # POST /notes # POST /notes.xml def create @subject = Subject.find(params[:subject_id]) @note = @subject.notes.create!(params[:note]) respond_to do |format| format.html { redirect_to(@subject) } end end end Finally this is my RSpec spec which should simply post my mocked objects to the NotesController and be executed... which it does: it "should create note and redirect to subject without javascript" do # usual rails controller test setup here subject = mock(Subject) Subject.stub(:find).and_return(subject) notes_proxy = mock('association proxy', { "create!" => Note.new }) subject.stub(:notes).and_return(notes_proxy) post :create, :subject_id => subject, :note => { :title => 'note title', :body => 'note body' } end The problem is that when the RSpec post method is called. The NotesController correctly handles the Mock Subject object, and create! the new Note object. However when the NoteController#Create method tries to redirect_to I get the following error: NoMethodError in 'NotesController should create note and redirect to subject without javascript' undefined method `spec_mocks_mock_url' for #<NotesController:0x1034495b8> Now this is caused by a bit of Rails trickery that passes an ActiveRecord object (@subject, in our case, which isn't ActiveRecord but a Mock object), eventually to url_for who passes all the options to the Rails' Routing, which then determines the URL. My question is how can I mock Subject so that the correct options are passed so that I my test passes. I've tried passing in :controller = 'subjects' options but no joy. Is there some other way of doing this? Thanks...

  • Why does by iPhone App cannot load NSURL when linked against iPhone OS SDK 4.0 and run on iPhone OS

    - by Tichel
    I have an iPhone App linked against iPhone SDK 4.0 but as deployment target I selected OS 3.1. When I start the application on my iPod touch running 3.1.3 I get an error that the class NSURL cannot be found: dyld: Symbol not found: _OBJC_CLASS_$_NSURL Referenced from: /var/mobile/Applications/21ECAA8E-8777-4020-82F5-56C510D0AEAE/myTracks4iPhoneOS.app/myTracks4iPhoneOS Expected in: /System/Library/Frameworks/CoreFoundation.framework/CoreFoundation in /var/mobile/Applications/21ECAA8E-8777-4020-82F5-56C510D0AEAE/myTracks4iPhoneOS.app/myTracks4iPhoneOS Data Formatters temporarily unavailable, will re-try after a 'continue'. (Not safe to call dlopen at this time.) mi_cmd_stack_list_frames: Not enough frames in stack. mi_cmd_stack_list_frames: Not enough frames in stack. When I declare CoreFoundation as weak framework then I am able to start the App. But the class NSURL itself does not work. Any idea? Thanks, Dirk

  • jQuery Validate() special function

    - by kevin
    I'm using the jQuery validate() plugin for some forms and it goes great. The only thing is that I have an input field that requires a special validation process. Here is how it goes: The jQuery validate plugin is called in the domready for all the required fields. Here is an example for an input: <li> <label for="nome">Nome completo*</label> <input name="nome" type="text" id="nome" class="required"/> </li> And here is how I call my special function: <li> <span id="sprytextfield1"> <label for="cpf">CPF* (xxxxxxxxxxx)</label> <input name="cpf" type="text" id="cpf" maxlength="15" class="required" /> <span class="textfieldInvalidFormatMsg">CPF Inv&aacute;lido.</span> </span> </li> And at the bottom of the file I call the Spry function: <script type="text/javascript"> <!-- var sprytextfield1 = new Spry.Widget.ValidationTextField("sprytextfield1","cpf"); //--> </script> Of course I call the Spry CSS and JavaScript files in the head section as well as my special-validate.js. When I just use the jQuery validate() plugin and click on the send button, the page goes automatically back to the first mistaken input field and shows the error type (not a number, not a valid email etc.). But with this new function, this "going-back-to-the-first-mistake" feature doesn't work, of course, because the validate() function sees it all good. I already added a rule for another form (about pictures upload) and it goes like this: $("#commentForm").validate({ rules: { foto34: { required: true, accept: "jpg|png|gif" } } }); Now my question is, how can I add the special validation function as a rule of the whole validation process? Here is the page to understand it better: link text and the special field is the first one: CPF. I hope I was clear explaining my problem.

  • SLF4J, Common Logging, console output

    - by Mauricio Scheffer
    I have this 3rd party library that has: slf4j-api-1.5.5.jar slf4j-jdk14-1.5.5.jar jcl-over-slf4j-1.5.5.jar I want to write some tests against this library and see its log output, and I don't want to add any more logging libraries (no log4j or anything else). I understand that SLF4J and Common Logging are both logging abstractions so I probably need to write my own simple concrete logger (or maybe not, since jcl-over-slf4j includes org.apache.commons.logging.impl.SimpleLog?). If so, what interfaces should I implement, and more importantly, how do I set up SL4J/Common Logging to use my logger in my test? I read in the SLF4J docs that I have to modify the StaticLoggerBinder class... does that really mean that I actually have to download SLF4J sources, modify the class and recompile it?

  • [PHP] Difference between normal and magic setters and getters

    - by Saif Bechan
    I am using a magic getter/setter class for my session variables, but I don't see any difference between normal setters and getters. The code: class session { public function __set($name, $value) { $_SESSION[$name] = $value; } public function __unset($name) { unset($_SESSION[$name]); } public function __get($name) { if(isset($_SESSION[$name])) { return $_SESSION[$name]; } } } Now the first thing I noticed is that I have to call $session->_unset('var_name') to remove the variable, nothing 'magical' about that. Secondly when I try to use $session->some_var this does not work. I can only get the session variable using $_SESSION['some_var']. I have looked at the PHP manual but the functions look the same as mine. Am I doing something wrong, or is there not really anything magic about these functions.

I have no clue how to proceed now, any idea guys? :)

  • file reading in python

    - by Jagdev
    So my whole problem is that I have two files one with following format(for Python 2.6): #comments config = { #comments 'name': 'hello', 'see?': 'world':'ABC',CLASS=3 } This file has number of sections like this. Second file has format: [23] [config] 'name'='abc' 'see?'= [23] Now the requirement is that I need to compare both files and generate file as: #comments config = { #comments 'name': 'abc', 'see?': 'world':'ABC',CLASS=3 } So the result file will contain the values from the first file, unless the value for same attribute is there in second file, which will overwrite the value. Now my problem is how to manipulate these files using Python. Thanks in advance and for your previous answers in short time ,I need to use python 2.6

  • hibernate column uniqueness question

    - by Seth
    I'm still in the process of learning hibernate/hql and I have a question that's half best practices question/half sanity check. Let's say I have a class A: @Entity public class A { @Id @GeneratedValue(strategy=GenerationType.AUTO) private Long id; @Column(unique=true) private String name = ""; //getters, setters, etc. omitted for brevity } I want to enforce that every instance of A that gets saved has a unique name (hence the @Column annotation), but I also want to be able to handle the case where there's already an A instance saved that has that name. I see two ways of doing this: 1) I can catch the org.hibernate.exception.ConstraintViolationException that could be thrown during the session.saveOrUpdate() call and try to handle it. 2) I can query for existing instances of A that already have that name in the DAO before calling session.saveOrUpdate(). Right now I'm leaning towards approach 2, because in approach 1 I don't know how to programmatically figure out which constraint was violated (there are a couple of other unique members in A). Right now my DAO.save() code looks roughly like this: public void save(A a) throws DataAccessException, NonUniqueNameException { Session session = sessionFactory.getCurrentSession(); try { session.beginTransaction(); Query query = null; //if id isn't null, make sure we don't count this object as a duplicate if(obj.getId() == null) { query = session.createQuery("select count(a) from A a where a.name = :name").setParameter("name", obj.getName()); } else { query = session.createQuery("select count(a) from A a where a.name = :name " + "and a.id != :id").setParameter("name", obj.getName()).setParameter("name", obj.getName()); } Long numNameDuplicates = (Long)query.uniqueResult(); if(numNameDuplicates > 0) throw new NonUniqueNameException(); session.saveOrUpdate(a); session.getTransaction().commit(); } catch(RuntimeException e) { session.getTransaction().rollback(); throw new DataAccessException(e); //my own class } } Am I going about this in the right way? Can hibernate tell me programmatically (i.e. not as an error string) which value is violating the uniqueness constraint? By separating the query from the commit, am I inviting thread-safety errors, or am I safe? How is this usually done? Thanks!

    Hi everybody, I noticed a weird behaviour of iPhone OS when using decimal values. The simulator parse them from strings in a correct way but when I test the app on my iPhone it lose the decimal part. In particular, I store values in a dictionary that I retrieve in this way: Code: NSString *thickStr = [dictionary valueForKey:@"thickness"]; NSNumber *thickNum = [[[self class] numberFormatter] numberFromString:thickStr]; [self setSpessore:thickNum]; where the "numberFormatter" class is defined as below: Code: + (NSNumberFormatter *)numberFormatter { static NSNumberFormatter *_formatter; if (_formatter == nil) { _formatter = [[NSNumberFormatter alloc] init]; [_formatter setNumberStyle:NSNumberFormatterDecimalStyle]; [_formatter setFormatterBehavior:NSNumberFormatterBehavior10_4]; [_formatter setGeneratesDecimalNumbers:TRUE]; } return _formatter; } But it doesn't work! The App on iPhone keeps on convert the string to a simple integer, forgetting the decimal part, while the app on iPhone simulator works fine!

  • Java Logger with Servlets

    - by Sunny
    Hi Guys, I am using a wrapper class A which initializes the java.util.logger static class A { public static Logger logger; public static void init(){ logger = Logger.getLogger("test"); } Now, everywhere in my program I call A.init() and then logger.log("Message+uniqid"). But recently I moved to HTTP servlets and I am having problems. Basically, If a app is already running and the logger is logging... and someone else runs the app again, the logger from the previous instance stops and starts logging for the second one. Can anyone have a solution to how I should go about fixing this static variable issue? I can pass the logger into all constructor classes but thats really tedious. Any better solution would be appreciated..

  • How can I highlight empty fields in ASP.NET MVC 2 before model binding has occurred?

    - by Richard Poole
    I'm trying to highlight certain form fields (let's call them important fields) when they're empty. In essence, they should behave a bit like required fields, but they should be highlighted if they are empty when the user first GETs the form, before POST & model validation has occurred. The user can also ignore the warnings and submit the form when these fields are empty (i.e. empty important fields won't cause ModelState.IsValid to be false). Ideally it needs to work server-side (empty important fields are highlighted with warning message on GET) and client-side (highlighted if empty when losing focus). I've thought of a few ways of doing this, but I'm hoping some bright spark can come up with a nice elegant solution... Just use a CSS class to flag important fields Update every view/template to render important fields with an important CSS class. Write some jQuery to highlight empty important fields when the DOM is ready and hook their blur events so highlights & warning messages can be shown/hidden as appropriate. Pros: Quick and easy. Cons: Unnecessary duplication of importance flags and warning messages across views & templates. Clients with JavaScript disabled will never see highlights/warnings. Custom data annotation and client-side validator Create classes similar to RequiredAttribute, RequiredAttributeAdapter and ModelClientValidationRequiredRule, and register the adapter with DataAnnotationsModelValidatorProvider.RegisterAdapter. Create a client-side validator like this that responds to the blur event. Pros: Data annotation follows DRY principle (Html.ValidationMessageFor<T> picks up field importance and warning message from attribute, no duplication). Cons: Must call TryValidateModel from GET actions to ensure empty fields are decorated. Not technically validation (client- & server-side rules don't match) so it's at the mercy of framework changes. Clients with JavaScript disabled will never see highlights/warnings. Clone the entire validation framework It strikes me that I'm trying to achieve exactly the same thing as validation but with warnings rather than errors. It needs to run before model binding (and therefore validation) has occurred. Perhaps it's worth designing a similar framework with annotations like Required, RegularExpression, StringLength, etc. that somehow cause Html.TextBoxFor<T> etc. to render the warning CSS class and Html.ValidationMessageFor<T> to emit the warning message and JSON needed to enable client-side blur checks. Pros: Sounds like something MVC 2 could do with out of the box. Cons: Way too much effort for my current requirement! I'm swaying towards option 1. Can anyone think of a better solution?

  • Java - AWT / Swing - handling the Event Descriptor Thread

    - by waitinforatrain
    Hi, I have a question about the 'Event Descriptor Thread'. I have a Main class that is also a JFrame. It initialises the rest of the components in the code, some of them do not involve Swing and some of them do. Is it enough to simply initialise the Main class using the EDT like this?... public static void main(String[] args) { javax.swing.SwingUtilities.invokeLater(new Runnable() { public void run() { new Main(); } }); } This way everything would run on the Event Dispatcher thread.
