  • What permissions do I need to grant to run RavenDB in Server mode?

    - by dalesmithtx
    I'm reading through Rob Ashton's excellent blog post on RavenDB: http://codeofrob.com/archive/2010/05/09/ravendb-an-introduction.aspx and I'm working through the code as I read. But when I try to add an index, I get a 401 error. Here's the code: class Program { static void Main(string[] args) { using (var documentStore = new DocumentStore() { Url = "http://localhost:8080" }) { documentStore.Initialise(); documentStore.DatabaseCommands.PutIndex( "BasicEntityBySomeData", new IndexDefinition<BasicEntity, BasicEntity>() { Map = docs => from doc in docs where doc.SomeData != null select new { SomeData = doc.SomeData }, }); string entityId; using (var documentSession = documentStore.OpenSession()) { var entity = new BasicEntity() { SomeData = "Hello, World!", SomeOtherData = "This is just another property", }; documentSession.Store(entity); documentSession.SaveChanges(); entityId = entity.Id; var loadedEntity = documentSession.Load<BasicEntity>(entityId); Console.WriteLine(loadedEntity.SomeData); var docs = documentSession.Query<BasicEntity>("BasicEntityBySomeData") .Where("SomeData:Hello~") .WaitForNonStaleResults() .ToArray(); docs.ToList().ForEach(doc => Console.WriteLine(doc.SomeData)); Console.Read(); } } } It throws the 401 error when on the line that makes the PutIndex() call. Any ideas what permissions I need to apply? And where I need to apply them?

  • Execute code on assembly load

    - by Dmitriy Matveev
    I'm working on wrapper for some huge unmanaged library. Almost every of it's functions can call some error handler deeply inside. The default error handler writes error to console and calls abort() function. This behavior is undesirable for managed library, so I want to replace the default error handler with my own which will just throw some exception and let program continue normal execution after handling of this exception. The error handler must be changed before any of the wrapped functions will be called. The wrapper library is written in managed c++ with static linkage to wrapped library, so nothing like "a type with hundreds of dll imports" is present. I also can't find a single type which is used by everything inside wrapper library. So I can't solve that problem by defining static constructor in one single type which will execute code I need. I currently see two ways of solving that problem: Define some static method like Library.Initialize() which must be called one time by client before his code will use any part of the wrapper library. Find the most minimal subset of types which is used by every top-level function (I think the size of this subset will be something like 25-50 types) and add static constructors calling Library.Initialize (which will be internal in that scenario) to every of these types. I've read this and this questions, but they didn't helped me. Is there any proper ways of solving that problem? Maybe some nice hacks available?

  • Using multiple sockets, is non-blocking or blocking with select better?

    - by JPhi1618
    Lets say I have a server program that can accept connections from 10 (or more) different clients. The clients send data at random which is received by the server, but it is certain that at least one client will be sending data every update. The server cannot wait for information to arrive because it has other processing to do. Aside from using asynchronous sockets, I see two options: Make all sockets non-blocking. In a loop, call recv on each socket and allow it to fail with WSAEWOULDBLOCK if there is no data available and if I happen to get some data, then keep it. Leave the sockets as blocking. Add all sockets to a fd_set and call select(). If the return value is non-zero (which it will be most of the time), loop through all the sockets to find the appropriate number of readable sockets with FD_ISSET() and only call recv on the readable sockets. The first option will create a lot more calls to the recv function. The second method is a bigger pain from a programming perspective because of all the FD_SET and FD_ISSET looping. Which method (or another method) is preferred? Is avoiding the overhead on letting recv fail on a non-blocking socket worth the hassle of calling select()? I think I understand both methods and I have tried both with success, but I don't know if one way is considered better or optimal. Only knowledgeable replies please!

  • Perl Script in background

    - by himz
    I have a perl script i made to automatically telnet into different servers . but its interface is only command line. To make it more user friendly for general windows users , i need to make GUI for it . My idea is to make GUI in a language like VB,java ,etc and let that call perl script . my script will run in background in a command prompt and whatever the result it displays back in GUI. Got some success. GUI in vb ,I run an instance of CMD in background ,run perl script in that .But that is wer program fails .As perl script runs in a thread for perl , i only get the output when script completes(rather say when it timeout). i need a mechanism where i can interact with the perl script , take output of script and show to user , then take input from user and so on . Please can you all suggest me some way to actually make this happen. PS: No limitation on using any language for GUI (as core work is done by perl script,GUI only there to give appropriate commands to script) Thanks in advance

  • convert password encryption from java to php

    - by Obay
    I'm trying to create a PHP version of an existing JSP program, however I'm stuck at the password encryption part. Could you please tell me how to convert this one? I know it tries to get the md5() but after that, I don't get it. I get lost in the Stringbuffer and for() parts. Can you help me out? public static String encryptPassword( String password ) { String encrypted = ""; try { MessageDigest digest = MessageDigest.getInstance( "MD5" ); byte[] passwordBytes = password.getBytes( ); digest.reset( ); digest.update( passwordBytes ); byte[] message = digest.digest( ); StringBuffer hexString = new StringBuffer(); for ( int i=0; i < message.length; i++) { hexString.append( Integer.toHexString( 0xFF & message[ i ] ) ); } encrypted = hexString.toString(); } catch( Exception e ) { } return encrypted; }

  • C# Inheritence: Choosing what repository based on type of inherited class

    - by Oskar Kjellin
    I have been making a program that downloads information about movies from the internet. I have a base class Title, which represents all titles. Movie, Serie and Episode are inherited from that class. To save them to the database I have 2 services, MovieService and SerieService. They in turn call repositories, but that is not important here. I have a method Save(Title title) which I am not very happy with. I check for what type the title is and then call the correct service. I would like to perhaps write like this: ITitleService service = title.GetService(); title.GetSavedBy(service); So I have an abstract method on Title that returns an ITitleSaver, which will return the correct service for the instance. My question is how should I implement ITitleSaver? If I make it accept Title I will have to cast it to the correct type before calling the correct overload. Which will lead to having to deal with casting once again. What is the best approach to dealing with this? I would like to have the saving logic in the corresponding class.

  • Rename a file with perl

    - by perlnoob
    I have a file in a different folder I want to rename in perl, I was looking at a solution earlier that showed something like this: for (<backup.rar>) { my $file = $_; my $new = $_ 'backup'. @test .'.rar'; rename $file, $new or die "Error, can not rename $file as $new: $!"; } however backup.rar is in a different folder, I did try putting "C:\backup\backup.rar" in the < above, however I got the same error. C:\Program Files\WinRARperl backup.pl String found where operator expected at backup.pl line 35, near "$_ 'backup'" (Missing operator before 'backup'?) syntax error at backup.pl line 35, near "$_ 'backup'" Execution of backup.pl aborted due to compilation errors. I was using # Get time my @test = POSIX::strftime("%m-%d-%Y--%H-%M-%S\n", localtime); print @test; To get the current time, however I couldn't seem to get it to rename correctly. What can I do to fix this? Please note I am doing this on a windows box.

  • How to determine the data type of a CvMat

    - by Chris
    When using the CvMat type, the type of data is crucial to keeping your program running. For example, depending on whether your data is type float or unsigned char, you would choose one of these two commands: cvmGet(mat, row, col); cvGetReal2D(mat, row, col); Is there a universal approach to this? If the wrong data type matrix is passed to these calls, they crash at runtime. This is becoming an issue, since a function I have defined is getting passed several different types of matrices. How do you determine the data type of a matrix so you can always access its data? I tried using the "type()" function as such. CvMat* tmp_ptr = cvCreateMat(t_height,t_width,CV_8U); std::cout << "type = " << tmp_ptr->type() << std::endl; This does not compile, saying "term does not evaluate to a function taking 0 arguments". If I remove the brackets after the word type, I get a type of 1111638032 EDIT minimal application that reproduces this... int main( int argc, char** argv ) { CvMat *tmp2 = cvCreateMat(10,10, CV_32FC1); std::cout << "tmp2 type = " << tmp2->type << " and CV_32FC1 = " << CV_32FC1 << " and " << (tmp2->type == CV_32FC1) << std::endl; } Output: tmp2 type = 1111638021 and CV_32FC1 = 5 and 0

  • Programmatically modifying a file on Windows Server 2008 (Web Ed.)

    - by Tom
    I have written a .NET 2008 application, incorporating Microsoft.Office.Interop.Excel, that modifies an existing Excel 2007 spreadsheet. It works perfectly on my WinXP development computer. When I upload the app to a Microsoft Web Server 2008, it opens the file and reads from the file, but when the app tries to save the file, it throws this exception: "System.Runtime.InteropServices.COMException (0x800A03EC): 'july2009.xlsx' is read-only. To save a copy, click OK, then give the workbook a new name in the Save As dialog box." The file is NOT read-only, nor is it opened by any other user or app. The app and the Excel file both reside on the D: (data-only) drive. My first instinct was to look at file permissions. When nothing else worked, I literally created a temporary Group, added EVERY user and security entity to it and granted the group full control of the entire D: drive. No luck. Then I tried manually elevating the permission by running my app as administrator. No luck. Finally, I copied the file to my XP development computer and ran the app there. Of course it worked perfectly. Can anyone please tell me how to give my program permission to edit a file on Server 2008? Thanks!

  • Finding a 3rd party QWidget with injected code & QWidget::find(hwnd)

    - by David Menard
    Hey, I have a Qt Dll wich I inject into a third-party Application using windows detours library: if(!DetourCreateProcessWithDll( Path, NULL, NULL, NULL, TRUE, CREATE_DEFAULT_ERROR_MODE | CREATE_SUSPENDED, NULL, NULL, &si, &pi, "C:\\Program Files\\Microsoft Research\\Detours Express 2.1\\bin\\detoured.dll", "C:\\Users\\Dave\\Documents\\Visual Studio 2008\\Projects\\XOR\\Debug\\XOR.dll", NULL)) and then I set a system-wide hook to intercept window creation: HHOOK h_hook = ::SetWindowsHookEx(WH_CBT, (HOOKPROC)CBTProc, Status::getInstance()->getXORInstance(), 0); Where XOR is my programs name, and Status::getInstance() is a Singleton where I keep globals. In my CBTProc callback, I want to intercept all windows that are QWidgets: HWND hwnd= FindWindow(L"QWidget", NULL); which works well, since I get a corresponding HWND (I checked with Spy++) Then, I want to get a pointer to the QWidget, so I can use its functions: QWidget* q = QWidget::find(hwnd); but here's the problem, the returned pointer is always 0. Am I not injecting my code into the process properly? Or am I not using QWidget::find() as I should? Thanks, Dave EDIT:If i change the QWidget::find() function to an exported function of my DLL, after setting the hooks (so I can set and catch a breakpoint), QWidgetPrivate::mapper is NULL.

  • ildasm and dynamic exe files

    - by TonyNeallon
    Hi There, I am trying to create an application can modify properties in IL to create a slightly different executable. E.g Client A runs app and a label on the WinForm label Reads "Client A:". Client B runs the app and Label Says "Client B". Easy I know using config files or resource files but thats not an option for this project. The Main program needs to be able to generate .exe file dynamically based on some form fields entered by user. My solution was to create a standalone executable that contained all the elements which I needed to make dynamic. I then used ildasm to generate the IL and thought that I could use this IL and substitute tags for the elements i wanted to make dynamic. I could then replace those tags at runtime after user filled the form using regex etc. The problem is, the if i re save the IL file generated by ILDASM as an exe and try to run it. I just launches console and does nothing. Am I going about this the wrong way? I didnt want to delve into Reflection as the dynamic .exe is a really simple one and I thought reverse engineering IL with ildasm would be the quickest way. You thoughts and pointers are much appreciated. Tony

  • What data structure to use / data persistence

    - by Dave
    I have an app where I need one table of information with the following fields: field 1 - int or char field 2 - string (max 10 char) field 3 - string (max 20 char) field 4 - float I need the program to filter on field 1 based upon a segmented control and select a field 2 from a picker. From this data I need to look up field 4 to use in a calculation. Total records will be about 200. I never see it go above 400 - 500. I am going to use a singleton which I am able to do, I just need help with the structure for this with data persistence. What type of data structure should I use for this and should I use NSNumber, NSString, etc. or old data types like float, Char, etc. I thought about a struct put into an array but there is probably a better way. This is new to me so any help or reference to examples would be great. I also thought about a plist or dictionary but it looks like it is just a lookup and a field which obviously won't work. Core data looked like overkill to me. Also, with any recommendation how should I get initial data into it? I want the user to be able to edit and add to the database. Sorry for the old terms, you can see what generation I am from... Thanks in advance!!!!

  • DDK/WDM developing problem ... driver won't load on x64 windows platform

    - by user295975
    Hi there! I am a beginner at DDK/WDM driver developing field. I have a task which involves porting a virtual device driver from x86 to x64 (intel). I got the source code, I modified it a bit and compiled it succesfuly with DDK (build environments). But when I tried to load it on a ia64 Windows7 machine it didn't want to load. Then I tried some simple examples of device drivers from --http://www.codeproject.com/KB/system/driverdev.aspx (I put '--' to be able to post the hyperlink) and from other links but still the same problem. I hear on a forum that some libraries that you use to link are not compatible with the new machines and suggested to link to another similar libraries...but still didn't worked. When I build I use "-cefw" command line parameters as suggested. I do not have an *.inf file asociated but I'm copying it in system32/drivers and I'm using WinObj to see if next restart it's loaded into the memory. I also tried this program ( http://www.codeproject.com/KB/system/tdriver.aspx ) to load the driver into the memory but still didn't worked for me. Please please help me...I'm stuck on this and my deadline already passed. I feel I'driving nuts in here trying to discover what am I doing wrong.

  • Is it possible to update old database from dbml file ? (C#, .Net 4, Linq, SQL Server)

    - by Emil
    Hi all, I began recently a new job, a very interesting project (C#,.Net 4, Linq, VS 2010 and SQL Server). And immediately I got a very exciting challenge: I must implement either a new tool or integrate the logic when program start, or whatever, but what must happen is the following: the customers have previous application and database (full with their specific data). Now a new version is ready and the customer gets the update. In the mean time we made some modification on DB (new table, columns, maybe an old column deleted, or whatever). I’m pretty new in Linq and also SQL databases and my first solution can be: I check the applications/databases version and implement all the changes step by step comparing all tables, columns, keys, constrains, etc. (all this new information I have in my dbml and the old I asked from the existing DB). And I’ll do this each time the version changed. But somehow I feel, this is NOT a smart solution so I look for a general solution of this problem. Is there a way to update customers DB from the dbml file? To create a new one is not a problem (CreateDatabase with DataContext), is there any update/alter database methods? I guess I’m not the only one who search for such a solution (I found nothing in internet – or I looked for bad keywords). How did you solve this problem? I look also for an external tool, but first for a solution with C#, Linq or something similar. For any idea thank you in advance! Best regards, Emil

  • Background worker not working right

    - by vbNewbie
    I have created a background worker to go and run a pretty long task that includes creating more threads which will read from a file of urls and crawl each. I tried following it through debugging and found that the background process ends prematurely for no apparent reason. Is there something wrong in the logic of my code that is causing this. I will try and paste as much as possible to make sense. While Not myreader.EndOfData Try currentRow = myreader.ReadFields() Dim currentField As String For Each currentField In currentRow itemCount = itemCount + 1 searchItem = currentField generateSearchFromFile(currentField) processQuerySearch() Next Catch ex As Microsoft.VisualBasic.FileIO.MalformedLineException Console.WriteLine(ex.Message.ToString) End Try End While This first bit of code is the loop to input from file and this is what the background worker does. The next bit of code is where the background worker creates threads to work all the 'landingPages'. After about 10 threads are created the background worker exits this sub and skips the file input loop and exits the program. Try For Each landingPage As String In landingPages pgbar.Timer1.Stop() If VisitedPages.Contains(landingPage) Then Continue For Else Dim thread = New Thread(AddressOf processQuery) count = count + 1 thread.Name = "Worm" & count thread.Start(landingPage) If numThread >= 10 Then For Each thread In ThreadList thread.Join() Next numThread = 0 Continue For Else numThread = numThread + 1 SyncLock ThreadList ThreadList.Add(thread) End SyncLock End If End If Next

  • VB .Net - Reflection: Reflected Method from a loaded Assembly executes before calling method. Why?

    - by pu.griffin
    When I am loading an Assembly dynamically, then calling a method from it, I appear to be getting the method from Assembly executing before the code in the method that is calling it. It does not appear to be executing in a Serial manner as I would expect. Can anyone shine some light on why this might be happening. Below is some code to illustrate what I am seeing, the code from the some.dll assembly calls a method named PerformLookup. For testing I put a similar MessageBox type output with "PerformLookup Time: " as the text. What I end up seeing is: First: "PerformLookup Time: 40:842" Second: "initIndex Time: 45:873" Imports System Imports System.Data Imports System.IO Imports Microsoft.VisualBasic.Strings Imports System.Reflection Public Class Class1 Public Function initIndex(indexTable as System.Collections.Hashtable) As System.Data.DataSet Dim writeCode As String MessageBox.Show("initIndex Time: " & Date.Now.Second.ToString() & ":" & Date.Now.Millisecond.ToString()) System.Threading.Thread.Sleep(5000) writeCode = RefreshList() End Function Public Function RefreshList() As String Dim asm As System.Reflection.Assembly Dim t As Type() Dim ty As Type Dim m As MethodInfo() Dim mm As MethodInfo Dim retString as String retString = "" Try asm = System.Reflection.Assembly.LoadFrom("C:\Program Files\some.dll") t = asm.GetTypes() ty = asm.GetType(t(28).FullName) 'known class location m = ty.GetMethods() mm = ty.GetMethod("PerformLookup") Dim o as Object o = Activator.CreateInstance(ty) Dim oo as Object() retString = mm.Invoke(o,Nothing).ToString() Catch Ex As Exception End Try return retString End Function End Class

  • How to remove view from window?

    - by Wayfarer
    I am using Cocos2D for my main framework. In some cases, I want Cocos2D to load a nib file and have that be the view: window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; TargetPlayerViewController *myController = [[TargetPlayerViewController alloc]initWithNibName:@"TargetPlayerViewController" bundle:nil]; [window addSubview:[myController view]]; [window makeKeyAndVisible]; This works as expected, and shows the TargetPlayerViewController. Wonderful! What I need to know is: once that view has been loaded, how can I have the view remove itself? I've tried a few different ways, but all of them result in the program crashing. To test I have a button on the view set up which triggers this method: - (IBAction)GTFOnow:(id)sender { NSLog(@"GFTO"); window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; //[self.view removeFromSuperview]; //[window makeKeyAndVisible]; } In this method the view should remove itself from the view so I can go back to the Cocos2D. How do I do this?

  • Outlook 2010 Retrieving and restricting appointments programmatically causing recurrences to be incl

    - by Mike Dearing
    I wrote a winforms app that uses Microsoft.Office.Interop.Outlook to retrieve and restrict appointments based upon the date range entered by a user. This worked fine with Outlook 2007 installed, however now that some users have updated to Outlook 2010 the appointment retrieval is pulling back incorrect appointments along with the correct ones falling within the specified date range. The additional incorrect appointments being retrieved always appear to be recurring appointments. I was wondering if this is a known bug and if so what exactly is happening that is causing these additional recurring appointments to come in? I'd rather not have to throw in a workaround where I step through the items after they have been restricted and remove the extra ones, when this functionality works fine with 2007. Note: I've not recompiled or updated any code when experiencing this issue, just running the old program. This is the spot in my code where appointments are being restricted. This is similar to the way advised in the following msdn link: http://msdn.microsoft.com/en-us/library/bb611267.aspx Microsoft.Office.Interop.Outlook.Items outlookItems = outlookMapiFolder.Items.Restrict( "[Start] >= '" + outlookImport.startDay.ToString("g") + "' AND [Start] <= '" + outlookImport.endDay.ToString("g") + "'"); outlookItems.Sort("[Start]", Type.Missing); outlookItems.IncludeRecurrences = true;

    I'm having a bit of trouble getting my app to show up in the market under GoogleTV.

  • Writing XML in different character encodings with Java

    - by Roman Myers
    I am attempting to write an XML library file that can be read again into my program. The file writer code is as follows: XMLBuilder builder = new XMLBuilder(); Document doc = builder.build(bookList); DOMImplementation impl = doc.getImplementation(); DOMImplementationLS implLS = (DOMImplementationLS) impl.getFeature("LS", "3.0"); LSSerializer ser = implLS.createLSSerializer(); String out = ser.writeToString(doc); //System.out.println(out); try{ FileWriter fstream = new FileWriter(location); BufferedWriter outwrite = new BufferedWriter(fstream); outwrite.write(out); outwrite.close(); }catch (Exception e){ } The above code does write an xml document. However, in the XML header, it is an attribute that the file is encoded in UTF-16. when i read in the file, i get the error: "content not allowed in prolog" this error does not occur when the encoding attribute is manually changed to UTF-8. I am trying to get the above code to write an XML document encoded in UTF-8, or successfully parse a UTF-16 file. the code for parsing in is DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance(); DocumentBuilder loader = factory.newDocumentBuilder(); Document document = loader.parse(filename); the last line returns the error.

  • How do I find a source code position from an address given by a crash in Window CE

    - by Shane MacLaughlin
    I have a Windows mobile 4.0 application, written using EVC++ 4.0 SP4 with MFC, that is exhibiting a random occasional crash in the field. e.g. Exception ox800000002 at 00112584. It does not happen under various emulators and simulators, hence is very difficult to trace using a debugger. The crash throws up and address and exception type. Given that I have the PDB is there any way to track this address to the source. I can't recompile using VC++ 8 as it doesn't support the mobile 4 SDK. My guess is that without a stack trace I'm not going to have much joy, as the chances are that the exception may not be in my source. Worth a try all the same. Edit As suggested, I have looked at the address in the context of the .MAP file for the program. This reveals the following Address Publics by Value Rva+Base Lib:Object 0001:00000000 ?GetUnduValue@@YANMM@Z 00011000 f 7Par.obj ' ' ' 0001:001124b8 ?OnLButtonUp@CGXGridUserDragSelectRangeImp@@UAAHPAVCGXGridCore@@AAVCPoint@@AAI@Z 001234b8 f gxseldrg.obj 0001:001126d8 ?OnSelDragStart@CGXGridUserDragSelectRangeImp@@UAAHPAVCGXGridCore@@KK@Z 001236d8 f gxseldrg.obj Which suggests the error occured during CGXGridUserDragSelectRangeImp::OnLButtonUp(), which seems a bit odd as I don't think there was a mouse / keyboard / screen button pressed at the time. Could be the stack got fragged before the crash got reported, and I'm wasting my time. I'll recompile with assembler output to try to isolate it to a given line, but don't hold out much hope :( Does the fact that the map file reports segmented addresses e.g. 0001:xxxxxxxxx and the crash report unsegmented addresses mean I have to carry out some computation to get the map address from the crash address?

The problem is that whenever I push the cut button , the file doesn't get saved until I close the application thanks ...................... void play_cut() { try { // First, we get the format of the input file final AudioFileFormat.Type fileType = AudioSystem.getAudioFileFormat(inputAudio).getType(); // Then, we get a clip for playing the audio. c = AudioSystem.getClip(); // We get a stream for playing the input file. AudioInputStream ais = AudioSystem.getAudioInputStream(inputAudio); // We use the clip to open (but not start) the input stream c.open(ais); // We get the format of the audio codec (not the file format we got above) final AudioFormat audioFormat = ais.getFormat(); // We add a shutdown hook, an anonymous inner class. Runtime.getRuntime().addShutdownHook(new Thread() { public void run() { // We're now in the hook, which means the program is shutting down. // You would need to use better exception handling in a production application. try { // Stop the audio clip. c.stop(); // Create a new input stream, with the duration set to the frame count we reached. Note that we use the previously determined audio format AudioInputStream startStream = new AudioInputStream(new FileInputStream(inputAudio), audioFormat, c.getLongFramePosition()); // Write it out to the output file, using the same file type. AudioSystem.write(startStream, fileType, outputAudio); } catch(IOException e) { e.printStackTrace(); } } }); // After setting up the hook, we start the clip. c.start(); } catch (UnsupportedAudioFileException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } catch (LineUnavailableException e) { e.printStackTrace(); } }// end play_cut ......................

  • Performance of java on different hardware?

    - by tangens
    In another SO question I asked why my java programs run faster on AMD than on Intel machines. But it seems that I'm the only one who has observed this. Now I would like to invite you to share the numbers of your local java performance with the SO community. I observed a big performance difference when watching the startup of JBoss on different hardware, so I set this program as the base for this comparison. For participation please download JBoss 5.1.0.GA and run: jboss-5.1.0.GA/bin/run.sh (or run.bat) This starts a standard configuration of JBoss without any extra applications. Then look for the last line of the start procedure which looks like this: [ServerImpl] JBoss (Microcontainer) [5.1.0.GA (build: SVNTag=JBoss_5_1_0_GA date=200905221634)] Started in 25s:264ms Please repeat this procedure until the printed time is somewhat stable and post this line together with some comments on your hardware (I used cpu-z to get the infos) and operating system like this: java version: 1.6.0_13 OS: Windows XP Board: ASUS M4A78T-E Processor: AMD Phenom II X3 720, 2.8 GHz RAM: 2*2 GB DDR3 (labeled 1333 MHz) GPU: NVIDIA GeForce 9400 GT disc: Seagate 1.5 TB (ST31500341AS) Use your votes to bring the fastest configuration to the top. I'm very curious about the results. EDIT: Up to now only a few members have shared their results. I'd really be interested in the results obtained with some other architectures. If someone works with a MAC (desktop) or runs an Intel i7 with less than 3 GHz, please once start JBoss and share your results. It will only take a few minutes.

  • Can i use the open source rich text editor in my site ? what does this GNU do with that ?

    - by Shyju
    I want to use one rich text editor to one of my ASP page.I searched in internet and found that there are lot of open source items available like TinyMCE,FCK Editror,nice edit etc.. Can i put the same samples in my website.There is a GNU license associated with it.Can somebody interpret it for me to answer these questions 1 . Can i use it in my website without getting a permission from anyone ? 2 . Do i need maintain the same files always ? Can i make some customization and use it ? Customization is only the CSS changes its going to be. 3 . Do i need to put all the files as it is of the package which downloaded.because my download has samples which supports all languages. Do i need to put all those folders too From GNU license " if you distribute copies of such a program, whether gratis or for a fee, you must pass on to the recipients the same freedoms that you received. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights."
