  • selenium and firefox timeout behavior

    - by Md. Reazul Karim
    I am facing this strange timeout behavior. I tried to load some page using: WebDriver drv = new FirefoxDriver(); drv.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS); drv.get(url); String email = ""; try { WebElement aElem = Util.safeFindElementByXpath(drv, "//p[1]/a[1]"); if (aElem != null) { email = aElem.getAttribute("href"); } } catch (Exception e) { } drv.quit(); return email; The safeFindElementByXpath is: static WebElement safeFindElementByXpath(WebDriver driver, String xpath) { try { return driver.findElement(By.xpath(xpath)); } catch (NoSuchElementException e) { return null; } } Now I set the firefox network.http.connection-timeout and network.http.connection-retry-timeout both to 10. Now if I restart the firefox I can see the new values. But if I try to run the above code - the firefox window opens and it waits for a particular website for a long time. Hence I open another tab in the same firefox window and check the values of timeout and find them to be 90 and 250. If I change the values on that same window, the selenium code immediately finishes requesting for the page (ie it goes after the exception block). So the thing is that the same code will work on many sites and I don't know beforehand which site is invalid/down and I was thinking of putting this code in a separate thread and kill the thread after some time from the calling thread. But that is not possible I guess because the child thread has no way to poll anything as it is stuck at page request and can't go to the polling code afterwards. Now the thing is that I want any kind of hack/workaround to accomplish this: try getting the emails for good sites and if there are bad sites just give up after a certain period (press the panic button sorta thing). Thanks

  • Full and Partial Matching of Sets

    - by jeffrey
    I have several sets of the same type [Y, M, D] and am trying to write a function to search these sets and return an array of the available sets that fit my parameters. ReturnedSets = return_matches(Y,M,D); I want the three parameters of the function return_matches to be optional. Which means any combination of values can be used to return the sets. For example, one could write - return_matches(13,null,2); - and the function would look for all sets that contain [13, anyValue, 2]; I'm writing this in PHP, to allow users to manage dated files on my website, but I'd like to be able to use this function again for other uses. Thanks! edit: (This, or variations of this, is all I can come up with so far... There is something extra that I don't understand, because this function ends up / would not work to return sets that contain y and d, but leaving m arbitrary. if(y == s[0]){ if(m == s[1]){ if(d == s[2]){ print "day match"; } } else {print "month match";} } else {print "year match";} } else {print "no match";}

  • Make text appear briefly in a JPanel

    - by Roo
    Hi, I am trying to make text appear briefly before it disappears. It would be along the lines of 1) Set color to black 2) wait x amount of seconds 3) set color to background color The method I call is repaint(), which then calls paintComponent(Graphics painter). repaint() is called only if I press the space-bar. I thought of trying repaint();Thread.sleep(1000);repaint(); (I do catch the Interrupt exception, just not shown), but it only calls paintComponent once per space-bar . Is there an easy way to do this or is this something that is a bit challenging?

  • how to pass user created connection to hibernate

    - by Mrityunjay
    hi, is there any way, to restrict hibernate not to create connection of its own(what we define in hibernate.properties or hibernate.cfg.xml), instead i can create and pass the connection to hibernate for further processing. The problem is that i need to set the ApplicationContext on the connection given that the i am using oracle connection. I know how to create a connection and set the applicationContext on to it.. but the problem is that i don't know how to force hibernate to use the connection that i have created.. Please help..

  • Can I set a timeout for a InputStream's read() function?

    - by Zombies
    I have a DataInputStream that I obtained from a Socket. Is there any way I can set a timeout for dis.read(...)? Currently I spawn a new thread to do the read. While the parent thread does a thread.join(timeout) to wait before interrupting it. I am aware of nio, but I don't think I want to refactor that much at this point. Thanks.

  • Evaluating creation of GUI via file vs coding

    - by nevets1219
    I'm working on a utility that will be used to test the project I'm currently working on. What the utility will do is allow user to provide various inputs and it will sends out requests and provide the response as output. However, at this point the exact format (which input is required and what is optional) has yet to be fleshed out. In addition, coding in Swing is somewhat repetitive since the overall work is simple though this should be the safest route to go as I have more or less full control and every component can be tweaked as I want. I'm considering using a configuration file that's in XML to describe the GUI (at least one part of it) and then coding the event handling part (in addition to validation, etc). The GUI itself shouldn't be too complicated. For each type of request to make there's a tab for the request and within each tab are various inputs. There seems to be quite a few questions about this already but I'm not asking for a 3rd party library to do this. I'm looking to do this myself, since I don't think it'll be too overly complicated (hopefully). My main consideration for using this is re-usability (later on, for other projects) and for simplifying the GUI work. My question is: are there other pros/cons that I'm overlooking? Is it worth the (unknown) time to do this? I've built GUI in VB.NET and with Flex3 before.

  • Android: The concept for detecting changes of an opened file

    - by niko
    I wrote an application for video recording which stores the recording to a file. Currently I am looking for a way to implement some kind of "listener" to listen for file changes. The concept I would like to implement is the following: Check the file on a set period of time (for example one second), extract changes (get the data that was written in the last period) and do something with these data. I would be very thankful if anyone of you could give any suggestion or point to any useful resource that could help to solve the given problem.

  • I'm confused about Polymorphism

    - by Vtanathip
    I'm know polymorphism rule that we can send it via parameter like this code interface Animal { void whoAmI(); } class A implements Animal{ @Override public void whoAmI() { // TODO Auto-generated method stub System.out.println("A"); } } class B implements Animal{ @Override public void whoAmI() { // TODO Auto-generated method stub System.out.println("B"); } } class RuntimePolymorphismDemo { public void WhoRU(List t){ System.out.println(t.getClass()); } public static void main(String[] args) { A a = new A(); B b = new B(); RuntimePolymorphismDemo rp = new RuntimePolymorphismDemo(); rp.WhoRU(a); rp.WhoRU(b); } } but List<Example> examples = new ArrayList<Example>(); This code,I'm don't understand why we must use List. why we can't use like this? ArrayList<Example> examples = new ArrayList<Example>(); Because when we use List we can't use method that only have in ArrayList class like trimToSize() and How I know when to use or not use?

  • Matching Class arrays

    - by frinkz
    I'm writing a routine to invoke methods, found by a name and an array of parameter Class values Matching the Method by getName works, but when trying to match the given Class[] for parameters, and Method.getParameterTypes(), I'm having trouble. I assumed that this would work: Class[] searchParams = new Class[] { float.class, String.class }; Class[] methodParams = m.getParameterTypes(); if(methodParams == searchParams) { m.invoke(this, paramValues); } But apparantly not - m.invoke is never reached. I've checked, and methodParams gives the same classes as searchParams. The code below works, and picks the right method, but it seems like a very dirty way of doing things, I'm sure I'm missing something obvious. Class[] searchParams = new Class[] { float.class, String.class }; Class[] methodParams = m.getParameterTypes(); boolean isMatch = true; for(int i = 0; i < searchParams.length; i++) { if(!searchParams.getClass().equals(methodParams.getClass())) { isMatch = false; } } if(isMatch) { m.invoke(this, paramValues); }

  • How to create an ARGB_8888 pixel value?

    - by vidstige
    Say I want to create an array of pixel values to pass into the createBitmap method described here. I have three int values r, g, b in the range 0 - 0xff. How do I transform those into a opaque pixel p? Does the alpha channel go in the high byte or the low byte? I googled up the documentation but it only states that: Each pixel is stored on 4 bytes. Each channel (RGB and alpha for translucency) is stored with 8 bits of precision (256 possible values.) This configuration is very flexible and offers the best quality. It should be used whenever possible. So, how to write this method? int createPixel(int r, int g, int b) { retrurn ? }

  • Why is J2EE scalable?

    - by py213py
    I heard from various sources that J2EE is highly scalable, but to me it seems that you could never scale a J2EE application to the level of the google search engine or any other large website. I would like to hear the technical reasons why it is so scalable.

  • How to make a swing app aware of screen size change?

    - by Marton Sigmond
    Hi, while my swing app is running I change the size of the screen (e.g. from 1024x768 to 800x600). Is there any event I can listen to to be notified about this? Alternatively I could check the screen size in every couple of second, but the Toolkit.getScreenSize() keeps telling me the old value. How could I get the real screen size after the change? Environment: Linux (tested on SuSE ES 11 and Ubuntu 9.04) I appreciate your help. Marton

  • Struts 1 - problem in showing ActionMessages through a JSP page

    - by Yatendra Goel
    I am using Struts 1.3.10. I am trying to display ActionMessage and ActionError set by Action class through a JSP page. The problem is that the ActionErrors are displaying well but ActionMessages are not displaying. When I debug the application, I found that the messages (reference variable of ActionMessages) contains messages. I also saved those messages through saveMessages(request, messages) method of Action class. So, I think that the problem is in the JSP code through which I am trying to display those messages. The JSP code is as follows: <logic:messagesPresent> <ul id="messsages"> <html:messages id="msg" message="true"> <li><bean:write name="msg"/> </li> </html:messages> </ul> </logic:messagesPresent>

  • 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); } }

  • Print unique ascii characters in eclipse console

    - by Shaded
    Hey guys, Kind of a strange question but... here it goes. Recently my application threw an IOException that the text only had a clubs symbol in it (like the suit in cards) I know this is probably because there was a number in there that was cast to a char and printed to the screen, and I've found where that might have happened. The only problem is, I can't recreate it in eclipse because the eclipse console doesn't want to print those characters for me. All I get are boxes. I figure this is an encoding issue or something but I need eclipse to print out those characters just like the windows console would. Is there a setting I can change to do this?
