  - by thisisananth

  I have written an SAX parser in my Google App Engine Web application. in that I try to validate my xml file with an xsd. But I am getting an access control exception when my code is tyring to access that xsd. java.security.AccessControlException: access denied (java.io.FilePermission \WEB-INF\ApplicationResponse.xsd read) at java.security.AccessControlContext.checkPermission(AccessControlContext.java:264) at java.security.AccessController.checkPermission(AccessController.java:427) at java.lang.SecurityManager.checkPermission(SecurityManager.java:532) at com.google.appengine.tools.development.DevAppServerFactory$CustomSecurityManager.checkPermission(DevAppServerFactory.java:166) at java.lang.SecurityManager.checkRead(SecurityManager.java:871) at java.io.FileInputStream.(FileInputStream.java:100) at com.sun.org.apache.xerces.internal.impl.xs.XMLSchemaLoader.xsdToXMLInputSource(XMLSchemaLoader.java:830) at com.sun.org.apache.xerces.internal.impl.xs.XMLSchemaLoader.processJAXPSchemaSource(XMLSchemaLoader.java:708) at com.sun.org.apache.xerces.internal.impl.xs.XMLSchemaLoader.loadSchema(XMLSchemaLoader.java:554) at com.sun.org.apache.xerces.internal.impl.xs.XMLSchemaValidator.findSchemaGrammar(XMLSchemaValidator.java:2459) at com.sun.org.apache.xerces.internal.impl.xs.XMLSchemaValidator.handleStartElement(XMLSchemaValidator.java:1807) at com.sun.org.apache.xerces.internal.impl.xs.XMLSchemaValidator.startElement(XMLSchemaValidator.java:705) at com.sun.org.apache.xerces.internal.impl.XMLNSDocumentScannerImpl.scanStartElement(XMLNSDocumentScannerImpl.java:330) at com.sun.org.apache.xerces.internal.impl.XMLNSDocumentScannerImpl$NSContentDispatcher.scanRootElementHook(XMLNSDocumentScannerImpl.java:779) at com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl$FragmentContentDispatcher.dispatch(XMLDocumentFragmentScannerImpl.java:1794) at com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl.scanDocument(XMLDocumentFragmentScannerImpl.java:368) at com.sun.org.apache.xerces.internal.parsers.XML11Configuration.parse(XML11Configuration.java:834) at com.sun.org.apache.xerces.internal.parsers.XML11Configuration.parse(XML11Configuration.java:764) at com.sun.org.apache.xerces.internal.parsers.XMLParser.parse(XMLParser.java:148) at com.sun.org.apache.xerces.internal.parsers.AbstractSAXParser.parse(AbstractSAXParser.java:1242) at sax.SAXLocalNameCount.parse(SAXLocalNameCount.java:220) at com.sms2mint.InterfaceServlet.doGet(InterfaceServlet.java:54) Please let me know how to debug this?

• Retrieving saved checkboxes' name and values from database

  - by sermed

  I have a form with checkboxes, each one has a value. When the registered user select any checkbox the value is incremented (the summation) and then then registred user save his selection of checkbox if he satisfied with the result of summation into database all this work fine ...i want to enable the registred user to view his selection history by retriving and displaying the checkboxes he selected in a page with thier values ... How I can do that? I'm just able to save the selected checkboxes as choice 1, choice 2, for example .. I want to view the selected checkboxes that is saved in database as the appear in the page when the user first select them: for example if the registred user selects these 3 options LEAD DEEP KEEL (1825) FULLY BATTENED MAINSAIL (558) TEAK SIDE DECKS (2889) They will be saved as for example (choice1, choice2, choice3). But if he want to view selected checkboxes the appear exactly as first he selects them: LEAD DEEP KEEL (1825) FULLY BATTENED MAINSAIL (558) TEAK SIDE DECKS (2889) This is my user table: $query="CREATE TABLE User( user_id varchar(20), password varchar(40), user_type varchar(20), firstname varchar(30), lastname varchar(30), street varchar(50), city varchar(50), county varchar(50), post_code varchar(10), country varchar(50), gender varchar(6), dob varchar(15), tel_no varchar(50), vals varchar(50), email varchar(50))"; and the code to inser the options selected to database <?php include("databaseconnection.php"); $str = ''; foreach($_POST as $key => $val) if (strpos($key,'choice') !== false) $str .= $key.','; $query = "INSERT INTO User (vals) VALUES('$str')"; $result=mysql_query($query,$conn); if ($result) { (mysql_error(); } else { echo " done"; } ?> And this is my form: function checkTotal() { document.listForm.total.value = ''; var sum = 0; for (i=0;i

• Regex issue with comma's telling me there are 6 args, instead of intended 4

  - by Azher

  I have a scenario outline table that looks like the following: Scenario Outline: Verify Full ad details Given I am on the xxx classified home page And I have entered <headline> in the search field & clicked on search When I click on full details Then I should see <headline> <year> <mileage> <price> displaying correctly and successfully Examples: |headline |year |mileage |price | |alfa romeo 166 |2005 |73,000 |6,990 | When I run my scenario it spits out that I have 6 args. But what I thought, I should only have 4 args: headline, year, mileage and price. I am thinking that it is taking the comma's and what is before and after it as two seperate args. Is there any way that I can make cucumber think that there are only 4 args with the example below? I have looked at messing around with regex but I dont seem to be getting anywhere. Any help would be greatly appreciated.

• Fastest PNG decoder for .NET

  - by sboisse

  Our web server needs to process many compositions of large images together before sending the results to web clients. This process is performance critical because the server can receive several thousands of requests per hour. Right now our solution loads PNG files (around 1MB each) from the HD and sends them to the video card so the composition is done on the GPU. We first tried loading our images using the PNG decoder exposed by the XNA API. We saw the performance was not too good. To understand if the problem was loading from the HD or the decoding of the PNG, we modified that by loading the file in a memory stream, and then sending that memory stream to the .NET PNG decoder. The difference of performance using XNA or using System.Windows.Media.Imaging.PngBitmapDecoder class is not significant. We roughly get the same levels of performance. Our benchmarks show the following performance results: Load images from disk: 37.76ms 1% Decode PNGs: 2816.97ms 77% Load images on Video Hardware: 196.67ms 5% Composition: 87.80ms 2% Get composition result from Video Hardware: 166.21ms 5% Encode to PNG: 318.13ms 9% Store to disk: 3.96ms 0% Clean up: 53.00ms 1% Total: 3680.50ms 100% From these results we see that the slowest parts are when decoding the PNG. So we are wondering if there wouldn't be a PNG decoder we could use that would allow us to reduce the PNG decoding time. We also considered keeping the images uncompressed on the hard disk, but then each image would be 10MB in size instead of 1MB and since there are several tens of thousands of these images stored on the hard disk, it is not possible to store them all without compression.

• How to convert from hex-encoded string to a "human readable" string?

  - by John Jensen

  I'm using the Net-SNMP bindings for python and I'm attempting to grab an ARP cache from a Brocade switch. Here's what my code looks like: #!/usr/bin/env python import netsnmp def get_arp(): oid = netsnmp.VarList(netsnmp.Varbind('ipNetToMediaPhysAddress')) res = netsnmp.snmpwalk(oid, Version=2, DestHost='10.0.1.243', Community='public') return res arp_table = get_arp() print arp_table The SNMP code itself is working fine. Output from snmpwalk looks like this: <snip> IP-MIB::ipNetToMediaPhysAddress.128.10.200.6.158 = STRING: 0:1b:ed:a3:ec:c1 IP-MIB::ipNetToMediaPhysAddress.129.10.200.6.162 = STRING: 0:1b:ed:a4:ac:c1 IP-MIB::ipNetToMediaPhysAddress.130.10.200.6.166 = STRING: 0:1b:ed:38:24:1 IP-MIB::ipNetToMediaPhysAddress.131.10.200.6.170 = STRING: 74:8e:f8:62:84:1 </snip> But my output from the python script yields a tuple of hex-encoded strings that looks like this: ('\x00$8C\x98\xc1', '\x00\x1b\xed;_A', '\x00\x1b\xed\xb4\x8f\x81', '\x00$86\x15\x81', '\x00$8C\x98\x81', '\x00\x1b\xed\x9f\xadA', ...etc) I've spent some time googling and came across the struct module and the .decode("hex") string method, but the .decode("hex") method doesn't seem to work: Python 2.7.3 (default, Apr 10 2013, 06:20:15) [GCC 4.6.3] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> hexstring = '\x00$8C\x98\xc1' >>> newstring = hexstring.decode("hex") Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/lib/python2.7/encodings/hex_codec.py", line 42, in hex_decode output = binascii.a2b_hex(input) TypeError: Non-hexadecimal digit found >>> And the documentation for struct is a bit over my head.

  I have tested this on Windows XP SP3 and Windows 7 Ultimate in IE7 and IE8 (in all compatiblity modes) and it fails the same way on both.

• How to add deploy.jar to classpath?

  - by dma_k

  I am facing the problem: I need to add ${java.home}/lib/deploy.jar JAR file to classpath in the runtime (dynamically from java). The solution with Thread#setContextClassLoader(ClassLoader) (mentioned here) does not work because of this bug (if somebody can explain what is really a problem – you are welcome). The solution with -Xbootclasspath/a:"%JAVA_HOME%/jre/lib/deploy.jar" does not work well for me, because I want to have "pure executable jar" as a deliverable: no wrapping scripts please (more over %JAVA_HOME% may not be defined in user's environment in Windows for example, plus I need to write a script per platform) The solution with merging deploy.jar file into my deliverable works only if I make a build on Windows platform. Unfortunately, when the deliverable is produced on build server running on Linux, I got Linux-dependant JAR, which does not execute on Windows – it fails with the trace below. I have read How the Java Launcher Finds Classes and Java programming dynamics: Java classes and class loading articles but I've got no extra ideas, how to correctly handle this situation. Any advices or solutions are very welcomed. Trace: java.lang.NoClassDefFoundError: Could not initialize class com.sun.deploy.config.Config at com.sun.deploy.net.proxy.UserDefinedProxyConfig.getBrowserProxyInfo(UserDefinedProxyConfig.java:43) at com.sun.deploy.net.proxy.DynamicProxyManager.reset(DynamicProxyManager.java:235) at com.sun.deploy.net.proxy.DeployProxySelector.reset(DeployProxySelector.java:59) ... java.lang.NullPointerException at com.sun.deploy.net.proxy.DynamicProxyManager.getProxyList(DynamicProxyManager.java:63) at com.sun.deploy.net.proxy.DeployProxySelector.select(DeployProxySelector.java:166)

• Selenium Webdriver Java - looking for alternatives for Actions and Robot when performing drag-and-drop

  - by Ja-ke Alconcel

  I first tried Actions class and the drag-and-drop does work on different elements, however it was unable to locate the a specific draggable element on it's exact screen/webpage position. Here's the code I've used: Point loc = driver.findElement(By.id("thiselement")).getLocation(); System.out.println(loc); WebElement drag = driver.findElement(By.id("thiselement")); Actions test = new Actions(driver); test.dragAndDropBy(drag, 0, 60).build().perform(); I checked the element with it's pixel location and it prints (837, -52), which was somewhere on top of the webpage and was pixels away from the actual element. Then I tried using the Robot class and works perfectly fine on my script, but can only provide constant successful runs on a single test machine, running it with a different machine with different screen resolution and screen size will render the script to fail due to the dependency of Robot on the pixel location of the element. The sample code of the Robot script I'm using: Robot dragAndDrop = new Robot(); dragAndDrop.mouseMove(945, 166); //actual pixel location of the draggable element dragAndDrop.mousePress(InputEvent.BUTTON1_MASK); sleep(3000); dragAndDrop.mouseMove(945, 226); dragAndDrop.mouseRelease(InputEvent.BUTTON1_MASK); sleep(3000); Is there any alternative for Actions and Robot to automate drag-and-drop? Or maybe a help on working the script to work on Actions as I really can't use Robot. Thanks in advance.

• Popovercontroller doesn't display full

  - by user2959234

  I have an UIPopovercontroller in with an content that generate from an viewcontroller. popOverController = [[UIPopoverController alloc]initWithPopUp:emLightPopUp]; popOverController.delegate = self; // Get device position. CGRect position = {parentButton.frame.origin,emLightPopUp.popUpView.frame.size}; CGSize popUpViewFrameSize = emLightPopUp.popUpView.frame.size; Link screenshot: http://i.stack.imgur.com/AxqoG.png The issue is that when I change the position of select devices (touched button) upwards, the displayed popup will be resized like the screenshot. I already try to set content size inside the subclass of uipopover but it still doesn't work: self.popoverContentSize = emLightPopUp.popUpView.frame.size; EDIT: I solved this problems by calculate the position that display the popup and scroll the scrollview inside into an upper position. Check out this code: -(void)moveDeviceOutMiddleScreen:(id)deviceButton { UIButton* button = (UIButton*)deviceButton; CGFloat yPositionRange = button.frame.origin.y - self.floorZoomScrollView.contentOffset.y; int middle_top_y = 70; int middle_bottom_y = 166; if (yPositionRange > middle_top_y && yPositionRange < middle_bottom_y) { CGRect newRect = CGRectMake(self.floorZoomScrollView.contentOffset.x, self.floorZoomScrollView.contentOffset.y +yPositionRange*0.6, self.floorZoomScrollView.frame.size.width, self.floorZoomScrollView.frame.size.height); [self.floorZoomScrollView scrollRectToVisible:newRect animated:NO]; } } Thanks for your responses.

• Ubuntu 11 and 12 initially fast but later bogs down, CPU pegged

  - by uos??

  I started with Ubuntu 11 a few weeks ago. It's on a DELL M4300 with a OCZ SSD. Default setup, except that I've installed the proprietary NVIDIA graphics and BROADCOM wireless drivers. Dual boot with Windows. If I cold boot into Ubuntu, it is very fast, just like the Windows experience that I'm used to. But SOMETHING happens, and I haven't yet determined what, but the system gets incredibly slow and stays that way. At first I thought it had to do with Adobe Flash because it seemed to be triggered by sites with Flash. But then I removed Flash and the problem remains. I thought it was just an overheating problem, but I've now upgraded to 12.04 which supposedly fixes the overheating problems I've read about. Perhaps the heat situation was brought on by Flash in my early cases? So I installed Jupiter for CPU management, but the thermometer reports a familiar Windows-side temperature of 53 degrees Celsius. Switching Jupiter to lower performance doesn't help. When I check the System Monitor application, sorting by CPU usage, there are no obvious problem processes. However, in the graphs tab, both CPU cores are pegged at 100%! I notice that the slowness seems to be similar to the extremely bad performance I got prior to installing the NVIDIA drivers. I'm not sure if that helps. This is the strangest part to me - although the temperature seems OK, even after rebooting, the system remains slow - starting with GRUB2 which is very noticeably delayed, all the way through to either Ubuntu or Windows! That's right, even the Windows side suffers effects and takes several minutes to complete booting whereas normally (with my SSD) it's ready to use in 15 seconds. The only way to fix it is to shutdown and let the parts cool down. Or maybe it just needs to completely power off and boot rather than a soft reboot, temperature has nothing to do with it? - is that possible? But know that I have never had this problem in Windows, even if Windows gets very hot (135 F) a reboot would be enough time for it to recover. For this reason, I don't think it's a heat thing, but I can't imagine what else could be surviving the reboot. I'm entirely updated - there are no pending updates. I have the Post-Release updates of NVIDIA too, btw. If this sounds CLOSE to something you know about, but one of the details doesn't line up exactly, it might be a mistake in my perception. Are there tests you can suggest to rule something out?

I don't know the relationship of which scenarios GRUB2 is also slow, but WHEN it is slow, it is slow both before the menu appears and after the selection is made - although for the diagnosis of GRUB2 it is harder for me to tell what the normal speeds should be. With SSD, I would expect that GRUB2 could load instantly, and that the GRUB2 purple would disappear instantly after the selection. The only delay to be expected is the change in graphics modes (though I couldn't guess why that ever requires any noticeable time)

• Flash animations doesn't work

  - by sosen

  I have a following problem: I have Ubuntu 12.04 installed on my Athlon 1800+ + 1 GB RAM + Nvidia Geforce4 MMX 440 (pretty old configuration) and everything works just fine except Flash Player in my Web browser (tried Firefox and Chromium). Instead of movie/animation, I get blank space. I updated my system via update manager, checked the plugins (everything OK), installed and updated flash player one more time, installed Ubuntu restricted extras, tried Firefox's Flash Aid, even tried Youtube Html 5 (still the same result)... Please, help me! I enjoy working with Linux and Ubuntu is the first that works for me well (after Open Suse and Fedora) but I have no idea what is wrong now...

• Desktop interface crashes after software updates

  - by N.C. Weber

  Recently, after installing Ubuntu software updates on the evening of December 7th, 2012, my desktop interface crashes regularly leaving me with a command line screen with a long string of automated commands showing (I assume what goes on behind the pretty desktop). At first, I thought it was only crashing whenever I played DirectX games in WINE, but now it crashes if I open the native Firefox browser or if it's doing nothing at all but sitting there. Apport attempts to report the bugs after restart, but often they crash as well. I've done a SMART check on the hard drive, and everything report OK. No read errors, no bad sectors. I am using an Acer Extensa 4620Z Memory: 2.0 GiB Processor: Intel Pentium Dual CPU T2370 @ 1.73GHz x 2 GraphicsL: Intel 965GM x86/MMX/SSE2 OS: Ubuntu 12.10 32-bit Disk: 116.0 GB with 33.4 GB Available

  - by Nemo Peeters

  I have Ubuntu 12.04 on a Dell latitude E6410, I have a problem when using the VGA output I always have dual monitor and can't switch on the "mirror display" toggle under systems setting/displays. It's rather annoying when having to do presentation with a video projector. the option "mirror display" is in light grey and I can"t tick the box. Thanks for those who might have an idea how to resolve this? update: driver is: Intel® Ironlake Mobile x86/MMX/SSE2 card something like this ? description: VGA compatible controller product: Core Processor Integrated Graphics Controller vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 version: 02 width: 64 bits clock: 33MHz
