  • How to set the path to "context path" for uploaded files using Apache Common fileupload?

    - by BugKiller
    Hi, I'm using Apache common fileupload library with Netbeans 6.8 + Glassfish.I'm trying to change the current upload path to be in the current context path of the servlet , something like this: WEB-INF/upload so I wrote : File uploadedFile = new File("WEB-INF/upload/"+fileName); session.setAttribute("path",uploadedFile.getAbsolutePath()); item.write(uploadedFile); but I notice that the library save the uploaded files into glassfish folder , here what I get when I print the absolute path of the uploaded file : C:\Program Files\sges-v3\glassfish\domains\domain1\WEB-INF\upload\xx.rar My Question : How can I force the common fileupload to save the uploaded file in a path relative to the current servlet path , so I don't need to specify the whole path ? is this possible ?

  • iPhone: How to Maintain Original Image Size Thoughout Image Edits

    - by maddy
    hi, I am developing an iPhone app that resizes and merges images. I want to select two photos of size 1600x1200 from photo library and then merge both into a single image and save that new image back to the photo library. However, I can't get the right size for the merged image. I take two image views of frame 320x480 and set the view's image to my imported images. After manipulating the images (zooming, cropping, rotating), I then save the image to album. When I check the image size it shows 600x800. How do I get the original size of 1600*1200? I've been stuck on this problem from two weeks! Thanks in advance.

  • itunes sdk list albums

    - by Matt Facer
    Hi guys, I'm working on a new test app (just out of curiosity really) which is an add on to iTunes. I'm trying fairly basic things at the mo, and have managed to control volume, pause etc etc. I have a function from some demo code which loops through all the tracks in my main library and gets their album name... I then show the individual album name in my listbox. This is FAR from the best way to do it! Is there a way to query the library to get just the album names? I ultimately want to get to a point where I can have a list of albums (with images) - I click on the album name and that loads the associated tracks.... thanks for any help! (I'm using VB.net btw)

  • Allowing threads from python after calling a blocking i/o code in a python extension generated using

    - by SS
    I have written a python extension wrapping an existing C++ library live555 (wrapping RTSP client interface to be specific) in SWIG. The extension works when it is operated in a single thread, but as soon as I call the event loop function of the library, python interpreter never gets the control back. So if I create a scheduled task using threading.Timer right before calling the event loop, that task never gets executed once event loop starts. To fix this issue, I added Py_BEGIN_ALLOW_THREADS and Py_END_ALLOW_THREADS macros manually in the SWIG auto generated wrapper cxx file around every doEventLoop() function call. But now, I want to do the same (i.e. allow threads) when SWIG generates the code itself and not to change any code manually. Has anyone done something similar in SWIG? P.S. - I would also consider switching to any other framework (like SIP) to get this working. I selected SWIG over any other technology is because writing SWIG interface was really very easy and I just had to include the existing header files.

  • aio_write on linux with rtkaio is sometimes long

    - by Drakosha
    I'm using async io on linux with rtkaio library. In my tests everything works perfectly, but, in my real application i see that aio_write which is supposed to return very fast, is very slow. It can take more than 100 milis to write a 128KB to a O_DIRECT padded file. Both my test and the application use same I/O size, i check on the same file system (GFS). I added counting and i see that there are about 50% of async io operations that are short (shorter then 2 milis) and 50% that are long (longer than 2 milis). I also checked that the test and the application both use the same rtkaio library. I'm pretty lost, anyone any ideas where should i look? Another my related question: http://stackoverflow.com/questions/1799537/proc-sys-fs-aio-nr-is-never-higher-than-1024-aio-on-linux

  • How to make an HTTP request in a separate thread with timeout?

    - by Vitaly
    Hi, I haven't programmed in Delphi for a while and frankly didn't think I'll ever have to but... Here I am, desperately trying to find some information on the matter and it's so scarce nowadays, I can't find anything. So maybe you guys could help me out. Currently my application uses Synapse library to make HTTP calls, but it doesn't allow for setting a timeout. Usually, that's not a big problem, but now I absolutely must to have a timeout to handle any connectivity issues nicely. What I'm looking for, is a library (synchronous or not) that will allow making HTTP requests absolutely transparent for the user with no visible or hidden delays. I can't immediately kill a thread right now, and with possibility of many frequent requests to the server that is not responding, it's no good.

  • Update webreference gives troubles with different versions of dll

    - by Natrium
    In my application, I use some dll, let's say library.dll, version 1.0 In my webservice, I also use library.dll, but version 2.0 When I do an update of the webreference, the classes inside of the dll are also generated in the webreference. And this gives troubles because in my application, the classes that are defined in the dll now are also available in the reference and there is a mismatch. How can I solve this? I need to be able to tell the webservice to ignore the dll-code when updating the webreference in the one or the other way. I use Visual Studio 2008.

  • How can I programmatically find the IP address/netmask/gateway configured for a specific network dev

    - by Oren S
    Hi I would like to write a piece of code which checks, for each network device (e.g. eth0, lo, master devices) some statistics and configuration data about that device. I could find the statistics data (and most of the configuration data) in /sys/class/net/..., however, I couldn't find any C/C++ API or any entry in procfs/sysfs listing the inet addr, netmask and gateway. Some alternatives I checked: parsing the output from ifconfig/route/some other utilities: I don't want to start a subprocess every time I need to do the inspection. parsing /etc/sysconfig/network-scripts/: will give me only the start-up configuration, and not the current state. Also, since this code is intended for a product in my workplace, where every external library is inspected thoroughly (meaning it will take me forever to add any external library) I prefer solutions which rely on Linux native API and not external libraries. Thanks!

  • Kohana input & validation libraries - overlap?

    - by keithjgrant
    I'm familiarizing myself with Kohana. I've been reading up on the Input library, which automatically pre-filters GET and POST data for me, and the Validation libary, which helps with form validation. Should I use both together? The examples given in the Validation library documentation use the unfiltered $_POST array instead of $this->input->post(). Seems to me it would be more secure to chain the two, but the two sets of documentation seem to make no mention of each other, so I don't know if this would be redundant or not.

  • Who Knows AppWeb HTTP Server And It's Embedded PHP?

    - by Andi
    Hi all, on my search for a fast but comfortable web server I dropped into the homepage of EmbedThis(TM) AppWeb(TM) HTTP server. This one has 2 licencse models, GPLv2 and a commercial one with support. On the first view it looks good: the footprint is not too big, it is fast and it has a lot of configuration otions. The most important thing would be a fast PHP execution using a built-in PHP library. Unfortunately this PHP library doesn't include every option, especially "gettext" which one I need for I18N. My target platform is Linux on an embedded device with an ARM based CPU. Does anybody have experiences with the issues mentioned above? Kind regards, Andi

  • infoWindow on MarkerClusterer

    - by vishwanath
    I need infoWindow to be opened instead of zooming in map, when clicking on the ClusterMarker. I am using Gmaps util library MarkerClusterer for creating cluster of markers. I tried changing following line in markerclusterer.js ClusterMarker_.prototype = new GOverlay(); with ClusterMarker_.prototype = new GMarker(); so that I can get the openInfoWindow() function in the clustermarker, but that didnt worked out. Got some error. If possible, Please suggest solution so that this can be done with MarkerClusterer. Or else any other library which will be able to do this. Any help will be appreciated.

  • Quartz Window Services equivalent for Windows and X11?

    - by Jake Petroules
    What is the equivalent of Quartz Window Services for Windows and X11? I want to be able to capture individual windows with their decorations, shadows, etc., completely independent from each other. Basically what the Son of Grab example is able to do. http://developer.apple.com/mac/library/samplecode/SonOfGrab/Introduction/Intro.html Also it seems like it's not possible to capture non-top-level windows with QWS in Mac. For example I want to be able to capture a Java or Flash applet running inside Firefox. What other library would I need to use instead?

  • convert HTML to PDF with dynamic image using PD4ML

    - by vishwanath
    We are using PD4ML library to convert HTML to PDF. Is there any way with which I can include a image from the internet in my HTML to convert it into PDF. I am having problem in getting the image into PDF. I tried using base parameter in the PD4ML library but that didn't worked out. May be I am doing something wrong or PD4ML doesn't support including image from the internet. Because when I discussed my problem with other colleagues, found out that when we use the image from local server it gets to the PDF but image from internet don't. I am bound to use PD4ML, so solution with PD4ML only will be highly appreciated.

  • Error when using --static option with macrubyc

    I want to create a binary executable for a relatively simple script that would not require people to install macruby or HotCocoa. The script is here. I've understood that I want to use the --static option for the compiler and I'm using the following command: macrubyc -o postprocessor --static postprocessor.rb I get the following error: ld: library not found for -lLLVMBitWriter collect2: ld returned 1 exit status Error when executing `/usr/bin/g++ -o "postprocessor" -arch x86_64 -L/Library/Frameworks/MacRuby.framework/Versions/0.6/usr/lib -lmacruby-static -L/usr/local/lib -lpthread -lffi -lm -lLLVMBitWriter -lLLVMX86CodeGen -lLLVMX86Info -lLLVMSelectionDAG -lLLVMAsmPrinter -lLLVMJIT -lLLVMExecutionEngine -lLLVMCodeGen -lLLVMScalarOpts -lLLVMTransformUtils -lLLVMipa -lLLVMAnalysis -lLLVMTarget -lLLVMMC -lLLVMCore -lLLVMSupport -lLLVMSystem -lpthread -ldl -lxml2 -lobjc -lauto -licucore -framework Foundation "/var/folders/wU/wUGgoG1JGeKBgwalWLPMAU+++TI/-Tmp-/main-72203.o" "./postprocessor.o"' What should I do to get this running?

  • CMake & ExternalProject: Fails to find specific file

    - by Enrico
    Hi, we have some dependency libraries in our repository. The main part is build with cmake. Now the cmake-makefiles shall build the dependency libraries, which do not have a cmake build system. For one specific library there is a "Makefile.squirrel" which should be used. The cmakelists.txt for that library: cmake_minimum_required (VERSION 2.8) include(ExternalProject) ExternalProject_Add(squirrel, SOURCE_DIR "./" UPDATE_COMMAND "" BUILD_IN_SOURCE 1 CONFIGURE_COMMAND "" BUILD_COMMAND "make -f ${CMAKE_CURRENT_SOURCE_DIR}/Makefile.squirrel" INSTALL_COMMAND "" ) However, when running make I get an error message: [ 93%] Performing build step for 'squirrel,' /bin/sh: make -f /home/enrico/projekte/projectname/dependencies/SQUIRREL2/Makefile.squirrel: not found make[2]: *** [dependencies/SQUIRREL2/squirrel,-prefix/src/squirrel,-stamp/squirrel,-build] Error 127 make[1]: *** [dependencies/SQUIRREL2/CMakeFiles/squirrel,.dir/all] Error 2 make: *** [all] Error 2 ls -lA on /home/enrico/projekte/projectname/dependencies/SQUIRREL2/Makefile.squirrel shows that the file exists. Hardcoding the file path (not an option for the solution) does not work, too. any ideas or hints? Thanks, Enrico

  • How to find all the file handles by a process programmatically?

    - by kumar
    I have a process "x" which uses "system" C function to start ntpd daemon. I observed that ntpd are passed the open file descriptors of "x". ntpd holds on to the file descriptors even after original file is deleted. for ex: Some log files used by "x" are rotated out after sometime, but "ntpd" has file handle opened for these deleted files. Will it cause any problem? Alternatively I thought of setting "FD_CLOEXEC" flag for all the file descriptors before calling "system" function. But as we are running as an extension library to third process "x"( "x" loads our library based on some condition), there is no easy way to know about all the file descriptors process has opened. One way is to read /proc//fd and set "FD_CLOEXEC" for each file handle and reset it back after "system" function returns. I'm using Linux 2.16. Is there any other easy way to find all the file handlers? Thanks,

  • Read entire file in Scala?

    - by Brendan OConnor
    What's a simple and canonical way to read an entire file into memory in Scala? (Ideally, with control over character encoding.) The best I can come up with is: scala.io.Source.fromPath("file.txt").getLines.reduceLeft(_+_) or am I supposed to use one of Java's god-awful idioms, the best of which (without using an external library) seems to be: import java.util.Scanner import java.io.File new Scanner(new File("file.txt")).useDelimiter("\\Z").next() From reading mailing list discussions, it's not clear to me that scala.io.Source is even supposed to be the canonical I/O library. I don't understand what its intended purpose is, exactly. ... I'd like something dead-simple and easy to remember. For example, in these languages it's very hard to forget the idiom ... Ruby open("file.txt").read Ruby File.read("file.txt") Python open("file.txt").read()

  • "Use of undefined constant CURLOPT_PROTOCOLS and CURLPROTO_HTTP" but it works?

    - by Dave
    Hi on our dev environment we have show all errors, warnings and notices. I'm getting this: Notice: Use of undefined constant CURLOPT_PROTOCOLS - assumed 'CURLOPT_PROTOCOLS' in C:\notion\implementation\development\asterix\library\ExternalLibs\panda.php on line 69 Notice: Use of undefined constant CURLPROTO_HTTP - assumed 'CURLPROTO_HTTP' in C:\notion\implementation\development\asterix\library\ExternalLibs\panda.php on line 69 The code on line 69: curl_setopt($curl, CURLOPT_PROTOCOLS, CURLPROTO_HTTP); But the CURL code works, it goes off to the other server and retrieves whats necessary. What do these notices mean? Thanks very much.

  • FreeLibrary vs implicit unloading DLL

    - by Adil
    I have implemented a DLL including DllMain() entry function:- BOOL APIENTRY DllMain( HMODULE hModule, DWORD ul_reason_for_call, LPVOID lpReserved ) { case DLL_PROCESS_ATTACH: ... case DLL_THREAD_ATTACH: ... case DLL_THREAD_DETACH: ... case DLL_PROCESS_DETACH: ... } Unfortunately i made a mistake in DLL_PROCESS_DETACH case and accessing illegal memorey (access violation). I made a sample program which loads the library using LoadLibrary() function, uses the library function and finally call FreeLibrary() and return. When i executed this program, i didnt get any error message. But if i remove FreeLibrary(), in that case the DLL_PROCESS_DETACH case is executed implicitly and this time it gives error dialog box mentioning that there is access violation. Why calling FreeLibrary() suppress this error? OR internally it handles this exception? What is suggested way.

  • Media Foundation: another way to call IMFActivate::ShutdownObject?

    - by KenC
    Hi, Here is a question about IMFActivate::ActivateObject and IMFActivate::ShutdownObject in Media Foundation. According to MSDN, the component that calls ActivateObject is responsible for calling ShutdownObject. But there are two examples not following this rule: http://msdn.microsoft.com/en-us/library/dd388503%28VS.85%29.aspx and http://msdn.microsoft.com/en-us/library/dd317912%28VS.85%29.aspx In these two examples, they call ActivateObject and then release IMFActivate interface without calling ShutdownObject method. This is going to lead to memory leaking, right? Or there is another way to release the resource occupied by the object? (Can I use IMFMediaSource::Shutdown to release the object instead of using IMFActivate::ShutdownObject) Thanks in advance.
