• Most awkward/misleading method in Java Base API ?

  - by JG

  I was recently trying to convert a string literal into a boolean, when the method "boolean Boolean.getBoolean(String name)" popped out of the auto-complete window. There was also another method ("boolean Boolean.parseBoolean(String s)") appearing right after, which lead me to search to find out what were the differences between these two, as they both seemed to do the same. It turns out that what Boolean.getBoolean(String name) really does is to check if there exists a System property (!) of the given name and if its value is true. I think this is very misleading, as I'm definitely not expecting that a method of Boolean is actually making a call to System.getProperty, and just by looking at the method signature, it sure looks (at least to me) like it should be used to parse a String as a boolean. Sure, the javadoc states it clearly, but I still think the method has a misleading name and is not in the right place. Other primitive type wrappers, such as Integer also have a similar method. Also, it doesn't seem to be a very useful method to belong in the base API, as I think it's not very common to have something like -Darg=true. Maybe it's a good question for a Java position interview: "What is the output of Boolean.getBoolean("true")?". I believe a more appropriate place for those methods would be in the System class, e.g., getPropertyAsBoolean; but again, I still think it's unnecessary to have these methods in the base API. It'd make sense to have these in something like the Properties class, where it's very common to do this kind of type conversions. What do you think of all this ? Also, if there's another "awkward" method that you're aware of, please post it. N.B. I know I can use Boolean.valueOf or Boolean.parseBoolean to convert a string literal into a boolean, but I'm just looking to discuss the API design.

• Dynamcally resising an open Accordion

  - by alavers

  I have an Accordion and the height of its content can be dynamically resized. I would like to see the Accordion dynamically respond to the child item's height, but I'm having trouble doing this. <lt:Accordion Name="MyAccordion" SelectionMode="ZeroOrOne" HorizontalAlignment="Stretch"> <lt:AccordionItem Name="MyAccordionItem" Header="MyAccordion" IsSelected="True" HorizontalContentAlignment="Stretch" VerticalAlignment="Stretch"> <StackPanel> <Button Content="Grow" Click="Grow"/> <Button Content="Shrink" Click="Shrink"/> <TextBox Name="GrowTextBox" Text="GrowTextBox" Height="400" Background="Green" SizeChanged="GrowTextBox_SizeChanged"/> </StackPanel> </lt:AccordionItem> </lt:Accordion> private void Grow(object sender, System.Windows.RoutedEventArgs e) { GrowTextBox.Height += 100; } private void Shrink(object sender, System.Windows.RoutedEventArgs e) { GrowTextBox.Height -= 100; } private void GrowTextBox_SizeChanged(object sender, System.Windows.SizeChangedEventArgs e) { MyAccordion.UpdateLayout(); MyAccordionItem.UpdateLayout(); } Mind you, if I collapse and then re-open the accordion, it takes shape just the way I want, but I'd like this resizing to occur immediately when the child resizes. I feebly attempted to fix this by adding a SizeChanged event handler that calls UpdateLayout() on the Accordion and AccordionItem, but this doesn't have any visual effect. I can't figure out where proper resizing takes place inside the Accordion control. Does anyone have an idea?

• Loading JNI lib on Mac OS X?

  - by Clinton

  Background So I am attempting to load a jnilib (specifically JOGL) into Java on Mac OS X at runtime. I have been following along the relevant Stack Overflow questions: Maven and the JOGL Library Loading DLL in Java - Eclipse - JNI How to make a jar file that include all jar files The end goal for me is to package platform specific JOGL files into a JAR and unzip them into a temp directory and load them at start-up. I worked my problem back to simply attempting to load JOGL using hard-coded paths: File f = new File("/var/folders/+n/+nfb8NHsHiSpEh6AHMCyvE+++TI/-Tmp-/libjogl.jnilib"); System.load(f.toString()); f = new File ("/var/folders/+n/+nfb8NHsHiSpEh6AHMCyvE+++TI/-Tmp-/libjogl_awt.jnilib"); System.load(f.toString()); I get the following exception when attempting to use the JOGL API: Exception in thread "main" java.lang.UnsatisfiedLinkError: no jogl in java.library.path But when I specify java.library.path by adding the following JVM option: -Djava.library.path="/var/folders/+n/+nfb8NHsHiSpEh6AHMCyvE+++TI/-Tmp-/" Everything works fine. Question Is it possible use System.load (or some other variant) on Mac OS X as a replacement for -Djava.library.path that is invoked at runtime?

  - by Gandalf StormCrow

  I'm trying to read in a multi line string then split it then print it .. here is the string : 1T1b5T!1T2b1T1b2T!1T1b1T2b2T!1T3b1T1b1T!3T3b1T!1T3b1T1b1T!5T1*1T 11X21b1X 4X1b1X When I split the string with ! I get this without the last line string : 1T1b5T 1T1b5T1T2b1T1b2T 1T2b1T1b2T1T1b1T2b2T 1T1b1T2b2T1T3b1T1b1T 1T3b1T1b1T3T3b1T 3T3b1T1T3b1T1b1T 1T3b1T1b1T5T1*1T 5T1*1T11X21b1X 11X21b1X Here is my code : import java.io.BufferedInputStream; import java.util.Scanner; public class Main { public static void main(String args[]) { Scanner stdin = new Scanner(new BufferedInputStream(System.in)); while (stdin.hasNext()) { for (String line : stdin.next().split("!")) { System.out.println(line); for (int i = 0; i < line.length(); i++) { System.out.print(line.charAt(i)); } } } } } Where did I make the mistake, why is not reading in the last line? After I read in all lines properly I should go trough each line if I encounter number I should print the next char the n times the number I just read, but that is long way ahead first I need help with this. Thank you UPDATE : Here is how the output should look like : 1T1b5T 1T2b1T1b2T 1T1b1T2b2T 1T3b1T1b1T 3T3b1T 1T3b1T1b1T 5T1*1T 11X21b1X 4X1b1X Here is a solution in C(my friend solved it not me), but I'd stil wanted to do it in JAVA : #include <stdio.h> int main (void) { char row[134]; for (;fgets (row,134,stdin)!=NULL;) { int i,j=0; for (i=0;row[i]!='\0';i++) { if (row[i]<='9'&&row[i]>='1') j+=(row[i]-'0'); else if ((row[i]<='Z'&&row[i]>='A')||row[i]=='*') for (;j;j--) printf ("%c",row[i]); else if (row[i]=='b') for (;j;j--) printf (" "); else if (row[i]=='!'||row[i]=='\n') printf ("\n"); } } return 0; }

• problem with two key ranges in couchdb

  - by Duasto

  I'm having problem getting the right results in my coordinate system. To explain my system, I have this simple database that have x_axis, y_axis and name columns. I don't need to get all the data, I just need to display some part of it. For example, I have a coordinate system that have 10:10(meaning from x_axis -10 to 10 and from y_axis -10 to 10) and I want to display only 49 coordinates. In sql query I can do it something like this: "select * from coordinate where x_axis = -3 and x_axis <= 3 and y_axis = -3 y_axis <= 3" I tried this function but no success: "by_range": { "map": "function(doc) { emit([doc.x_axis, doc.y_axis], doc) }" } by_range?startkey=[-3,-3]&endkey=[3,3] I got a wrong results of: -3x-3 -3x-2 -3x-1 -3x0 -3x1 -3x2 -3x3 <-- should not display this part -- -3x4 -3x5 -3x6 -3x7 -3x8 -3x9 -3x10 <-- end of should not display this part -- ..... up to 3x3 to give you a better understanding of my project here is the screenshot of that I want to be made: Oops they don't allowed new poster to post an image img96(dot)imageshack(dot)us/img96/5382/coordinates(dot)jpg <<< just change the "(dot)" to "."

• Serialization of Entity Framework Models with .NET WCF Rest Service

  - by Chris Phillips

  I'm trying to put together a very simple REST-style interface for communicating with our partners. An example object in the API is a partner, which we'd like to have serialized like this: <partner> <id>ID</id> <name>NAME</name> </partner> This is fairly simply to achieve using the .NET 4.0 WCF REST template if we simply declare a partner class as: public class Partner { public int Id {get; set;} public string Name {get; set;} } But when I use the Entity Framework to define and store Partner objects, the resulting serialization looks something like this: <Partner p1:Id="NCNameString" p1:Ref="NCNameString" xmlns:p1="http://schemas.microsoft.com/2003/10/Serialization/" xmlns="http://schemas.datacontract.org/2004/07/TheTradeDesk.AdPlatform.Provisioning"> <EntityKey p1:Id="NCNameString" p1:Ref="NCNameString" xmlns="http://schemas.datacontract.org/2004/07/System.Data.Objects.DataClasses"> <EntityContainerName xmlns="http://schemas.datacontract.org/2004/07/System.Data">String content</EntityContainerName> <EntityKeyValues xmlns="http://schemas.datacontract.org/2004/07/System.Data"> ... This XML is obviously unacceptable for use as an external API. What are suggested mechanisms for using EF for the data store but maintaining a simple XML serialization interface?

  This is a Project Euler problem. If you don't want to see candidate solutions don't look here. Hello you all! im developping an application that will find the sum of all even terms of the fibonacci sequence. The last term of this sequence is 4,000,000 . There is something wrong in my code but I cannot find the problem since it makes sense to me.

• C# XML node with colon

  - by Sticky

  Hi, my code attempts to grab data from the RSS feed of a website. It grabs the nodes fine, but when attempting to grab the data from a node with a colon, it crashes and gives the error "Namespace Manager or XsltContext needed. This query has a prefix, variable, or user-defined function." The code is shown below: WebRequest request = WebRequest.Create("http://buypoe.com/external.php?type=RSS2&lastpost=true"); WebResponse response = request.GetResponse(); StringBuilder sb = new StringBuilder(""); System.IO.StreamReader rssStream = new System.IO.StreamReader(response.GetResponseStream(), System.Text.Encoding.GetEncoding("utf-8")); XmlDocument rssDoc = new XmlDocument(); rssDoc.Load(rssStream); XmlNodeList rssItems = rssDoc.SelectNodes("rss/channel/item"); for (int i = 0; i < 5; i++) { XmlNode rssDetail; rssDetail = rssItems.Item(i).SelectSingleNode("dc:creator"); if (rssDetail != null) { user = rssDetail.InnerText; } else { user = ""; } } I understand that I need to define the namespace, but am unsure how to do this. Help would be appreciated.

• A rectangle drawn with DrawingContext.DrawRectangle blocks mouse

  - by dharmatech

  The WPF program below puts up a window which looks like this: Mouse-movement outside the black square causes the window title to be updated with the mouse's position. The updating stops when the mouse enters the square. I'd like for MouseMove to continue to trigger even when the mouse is over the square. Is there a way to do this? using System.Windows; using System.Windows.Controls; using System.Windows.Media; namespace Wpf_Particle_Demo { class DrawingVisualElement : FrameworkElement { public DrawingVisual visual; public DrawingVisualElement() { visual = new DrawingVisual(); } protected override int VisualChildrenCount { get { return 1; } } protected override Visual GetVisualChild(int index) { return visual; } } public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); var canvas = new Canvas(); Content = canvas; var element = new DrawingVisualElement(); canvas.Children.Add(element); CompositionTarget.Rendering += (s, e) => { using (var dc = element.visual.RenderOpen()) dc.DrawRectangle(Brushes.Black, null, new Rect(0, 0, 50, 50)); }; MouseMove += (s, e) => Title = e.GetPosition(canvas).ToString(); } } }

• InputManager ignores cut/copy/paste when initiated from menu

  - by Wallstreet Programmer

  I'm using the InputManager to check if changes to controls are done by user or code. This works fine, except when user uses the context menu for cut/copy/paste. If the user do ctrl+v in a textbox, InputManager correctly notices it. However, if the paste is done from the context menu of the textbox, the InputManager never fires the PreNotifyInput or PostNotifyInput events. Anyone knows why? Or how to detect that these user actions? Below is a working sample. The lower textblock never gets updated when user uses the cut/copy/paste menu in the above textbox since PreNotifyInput never fires. XAML: <Window x:Class="InputMgrDemo.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Height="300" Width="300"> <StackPanel> <TextBox TextChanged="TextBox_TextChanged" /> <TextBlock Name="_text" /> </StackPanel> </Window> Code behind: using System.Windows; using System.Windows.Controls; using System.Windows.Input; namespace InputMgrDemo { public partial class Window1 : Window { public Window1() { InitializeComponent(); InputManager.Current.PreNotifyInput += ((sender, e) => _userInput = true); InputManager.Current.PostNotifyInput += ((sender, args) => _userInput = false); } private void TextBox_TextChanged(object sender, TextChangedEventArgs e) { if (_userInput) { _text.Text = (sender as TextBox).Text; } } private bool _userInput; } }

• Elegant code question: How to avoid creating unneeded object

  - by SeaDrive

  The root of my question is that the C# compiler is too smart. It detects a path via which an object could be undefined, so demands that I fill it. In the code, I look at the tables in a DataSet to see if there is one that I want. If not, I create a new one. I know that dtOut will always be assigned a value, but the the compiler is not happy unless it's assigned a value when declared. This is inelegant. How do I rewrite this in a more elegant way? System.Data.DataTable dtOut = new System.Data.DataTable(); . . // find table with tablename = grp // if none, create new table bool bTableFound = false; foreach (System.Data.DataTable d1 in dsOut.Tables) { string d1_name = d1.TableName; if (d1_name.Equals(grp)) { dtOut = d1; bTableFound = true; break; } } if (!bTableFound) dtOut = RptTable(grp);

• #include - brackets vs quotes in XCode?

  - by Chris Becke

  In MSVC++ #include files are searched for differently depending on whether the file is enclosed in "" or <. The quoted form searches first in the local folder, then in /I specified locations, The angle bracket form avoids the local folder. This means, in MSVC++, its possible to have header files with the same name as runtime and SDK headers. So, for example, I need to wrap up the windows sdk windows.h file to undefine some macro's that cause trouble. With MSVS I can just add a (optional) windows.h file to my project as long as I include it using the quoted form :- // some .cpp file #include "windows.h" // will include my local windows.h file And in my windows.h, I can pull in the real one using the angle bracket form: // my windows.h #include <windows.h> // will load the real one #undef ConflictingSymbol Trying this trick with GCC in XCode didn't work. angle bracket #includes in system header files in fact are finding my header files with similar names in my local folder structure. The MSVC system means its quite safe to have a "String.h" header file in my own folder structre. On XCode this seems to be a major no no. Is there some way to control this search path behaviour in XCode to be more like MSVC's? Or do I just have to avoid naming any of my headers anything that might possibly conflict with a system header. Writing cross platform code and using lots of frameworks means the possibility of incidental conflicts seems large.

• Can i change the identity of the logged in user in ASP.net?

  - by Rising Star

  I have an ASP.net application I'm developing authentication for. I am using an existing cookie-based log on system to log users in to the system. The application runs as an anonymous account and then checks the cookie when the user wants to do something restricted. This is working fine. However, there is one caveat: I've been told that for each page that connects to our SQL server, I need to make it so that the user connects using an Active Directory account. because the system I'm using is cookie based, the user isn't logged in to Active Directory. Therefore, I use impersonation to connect to the server as a specific account. However, the powers that be here don't like impersonation; they say that it clutters up the code. I agree, but I've found no way around this. It seems that the only way that a user can be logged in to an ASP.net application is by either connecting with Internet Explorer from a machine where the user is logged in with their Active Directory account or by typing an Active Directory username and password. Neither of these two are workable in my application. I think it would be nice if I could make it so that when a user logs in and receives the cookie (which actually comes from a separate log on application, by the way), there could be some code run which tells the application to perform all network operations as the user's Active Directory account, just as if they had typed an Active Directory username and password. It seems like this ought to be possible somehow, but the solution evades me. How can I make this work?

• what's the performance difference between int and varchar for primary keys

  - by user568576

  I need to create a primary key scheme for a system that will need peer to peer replication. So I'm planning to combine a unique system ID and a sequential number in some way to come up with unique ID's. I want to make sure I'll never run out of ID's, so I'm thinking about using a varchar field, since I could always add another character if I start running out. But I've read that integers are better optimized for this. So I have some questions... 1) Are integers really better optimized? And if they are, how much of a performance difference is there between varchars and integers? I'm going to use firebird for now. But I may switch later. Or possibly support multiple db's. So I'm looking for generalizations, if that's possible. 2) If integers are significantly better optimized, why is that? And is it likely that varchars will catch up in the future, so eventually it won't matter anyway? My varchar keys won't have any meaning, except for the unique system ID part. But I may want to obscure that somehow. Also, I plan to efficiently use all the bits of each character. I don't, for example, plan to code the integer 123 as the character string "123". So I don't think varchars will require more space than integers.

• Where to start when doing a Domain Model?

  - by devoured elysium

  Let's say I've made a list of concepts I'll use to draw my Domain Model. Furthermore, I have a couple of Use Cases from which I did a couple of System Sequence Diagrams. When drawing the Domain Model, I never know where to start from: Designing the model as I believe the system to be. This is, if I am modelling a the human body, I start by adding the class concepts of Heart, Brain, Bowels, Stomach, Eyes, Head, etc. Start by designing what the Use Cases need to get done. This is, if I have a Use Case which is about making the human body swallow something, I'd first draw the class concepts for Mouth, Throat, Stomatch, Bowels, etc. The order in which I do things is irrelevant? I'd say probably it'd be best to try to design from the Use Case concepts, as they are generally what you want to work with, not other kind of concepts that although help describe the whole system well, much of the time might not even be needed for the current project. Is there any other approach that I am not taking in consideration here? How do you usually approach this? Thanks

• What happens when we say "listen to a port" ?

  - by smwikipedia

  Hi, When we start a server application, we always need to speicify the port number it listens to. But how is this "listening mechanism" implemented under the hood? My current imagination is like this: The operating system associate the port number with some buffer. The server application's responsibiligy is to monitor this buffer. If there's no data in this buffer, the server application's listen operation will just block the application. When some data arrives from the wire, the operating system will know that check the data and see if it is targed at this port number. And then it will fill the buffer. And then OS will notify the blocked server application and the server application will get the data and continue to run. Question is: If the above scenario is correct, how could the opearting system know there's data arriving from wire? It cannot be a busy pooling. Is it some kind of interrupt-based mechanism? If there's too much data arriving and the buffer is not big enough, will there be data loss? Is the "listen to a port" operation really a blocking operation? Many thanks.

• What are salesforce.com and Apex like as an application development platform?

  - by mhollers

  I have recently discovered that salesforce.com is much more than an online CRM after coming across a Morrison's Case Study in which they develop a works management application. I've been trying it out with a view to recreating our own Works Management system on the platform. My background is in Microsoft and .Net, and the obvious 1st choice would be asp.net. However, there's only really myself with .net experience and my manager with a more legacy Synergy programming background, and I am self taught and am looking at evaluating other RAD options (eg Ironspeed). the nature of the business is in the main 2-5 concurrent construction type contracts that run for 3-5 yrs each, each requiring 15-50 system users. Traditionally we have used our character based Works Mangement system for everything and tweaked it for each contract. The Salesforce licensing model on the face of it suits this sort of flexibilty, but I'm worried about the development flexibilty/learning curve and all the issues that surround lock-in. There doesn't seem to be much neutral sober analysis of the platform on the web that isn't salesforce's own material/blogs Has anyone any experience of developing an application on salesforce as compared to the more 'traditional' .Net route?

• How can I debug a session

  - by Organ Grinding Monkey

  I have been asked to work of a very large web application and deploy it. The problem that I'm facing here is that when I deploy the application and more that 1 user logs into the system, the sessions seem to cross over i.e: Person A logs in and works on the site, all good. When person B logs in, person A will then be logged in as person B as well. I have been asked to work of a very large web application and deploy it. The problem that I'm facing here is that when I deploy the application and more that 1 user logs into the system, the sessions seem to cross over i.e: Person A logs in and works on the site, all good. When person B logs in, person A will then be logged in as person B as well. If anyone has experienced this behaviour before and can steer me in the right direction, that would be first prize, Second prize would be to show me how I can debug this situation so that I can find out where the problem is and fix it. Some information about the application. From what I've been told and what I've seen within the app is that it started as a .Net 1.1 application and got upgraded to .Net 2 and that's why the log in system was done the way it is. (The application is huge and now complete and that's why I cant rewrite the whole user authentication process, it will just take to long and I don't know what effect it might have) All the Logged in User information is stored in properties that have been added in the Global.asax.vb file. (could this be the problem?) Any help here would be greatly appreciated

• reporting tool/viewer for large datasets

  - by FrustratedWithFormsDesigner

  I have a data processing system that generates very large reports on the data it processes. By "large" I mean that a "small" execution of this system produces about 30 MB of reporting data when dumped into a CSV file and a large dataset is about 130-150 MB (I'm sure someone out there has a bigger idea of "large" but that's not the point... ;) Excel has the ideal interface for the report consumers in the form of its Data Lists: users can filter and segment the data on-the-fly to see the specific details that they are interested in - they can also add notes and markup to the reports, create charts, graphs, etc... They know how to do all this and it's much easier to let them do it if we just give them the data. Excel was great for the small test datasets, but it cannot handle these large ones. Does anyone know of a tool that can provide a similar interface as Excel data lists, but that can handle much larger files? The next tool I tried was MS Access, and found that the Access file bloats hugely (30 MB input file leads to about 70 MB Access file, and when I open the file, run a report and close it the file's at 120-150 MB!), the import process is slow and very manual (currently, the CSV files are created by the same plsql script that runs the main process so there's next to no intervention on my part). I also tried an Access database with linked tables to the database tables that store the report data and that was many times slower (for some reason, sqlplus could query and generate the report file in a minute or soe while Access would take anywhere from 2-5 minutes for the same data) (If it helps, the data processing system is written in PL/SQL and runs on Oracle 10g.)

• Line End Problem Reading with Scanner Class in Java

  - by dikbas

  I am not an experienced Java programmer and i'm trying to write some text to a file and then read it with Scanner. I know there are lots of ways of doing this, but i want to write records to file with delimiters, then read the pieces. The problem is so small. When I look the output some printing isn't seen(shown in below). I mean the bold line in the Output that is only written "Scanner". I would be appreciated if anyone can answer why "String: " isn't seen there. (Please answer just what i ask) I couldn't understand if it is a simple printing problem or a line end problem with "\r\n". Here is the code and output: import java.io.FileReader; import java.io.FileWriter; import java.io.IOException; import java.util.Scanner; public class Tmp { public static void main(String args[]) throws IOException { int i; boolean b; String str; FileWriter fout = new FileWriter("test.txt"); fout.write("Testing|10|true|two|false\r\n"); fout.write("Scanner|12|one|true|"); fout.close(); FileReader fin = new FileReader("Test.txt"); Scanner src = new Scanner(fin).useDelimiter("[|\\*]"); while (src.hasNext()) { if (src.hasNextInt()) { i = src.nextInt(); System.out.println("int: " + i); } else if (src.hasNextBoolean()) { b = src.nextBoolean(); System.out.println("boolean: " + b); } else { str = src.next(); System.out.println("String: " + str); } } fin.close(); } } Here is the output: String: Testing int: 10 boolean: true String: two String: false Scanner int: 12 String: one boolean: true

• Enterprise integration of disparate systems

  - by Chris Latta

  We're about to embark on a fairly large integration effort to kill off a bunch of Access and Sql Server databases and get everything into one coherent enterprise system. There are also a number of other systems (accounting, CRM, payroll, MS Exchange) that hold critical data that we need to integrate (use for data validation in other systems), report on and otherwise expose. It is likely that some of these systems will change in the next few years, so we need to isolate our systems to be ready for change. Ideally we would be able to expose our forms in a consistent manner across as many of our our systems as possible without having to re-develop them for each system. We are currently targeting SharePoint (2007 and soon 2010), Office (2007 and soon 2010 - Word, Excel, PowerPoint and Outlook), Reporting Services, .Net console applications, .Net Windows applications, shell extensions, and with the possibility of exposing some functionality on mobile devices (BlackBerries currently, maybe iPhones later) and via our website. We're moving development to Visual Studio 2010 (from 2005) ahead of migrating to SharePoint 2010 and Office 2010. Given that most of our development is presently targeted to the .Net framework (mostly in C#) it seems logical to stick with this unless there is some compelling reason to switch frameworks/platform for some aspects. We're thinking of your standard Database-Data Integration layer-Business Objects Layer-Web Services (or REST) layer-Client Application plus doing our own client application with WPF (or something else?) forms that can also be exposed in the MS systems (SharePoint, Office, Windows). So, we don't want much, just everything :) Basically we need to isolate ourselves from database and systems changes, create an API that can be used throughout our systems and then make this functionality available in our client applications. I'm very keen to get pointers from anyone who has tips on how to pull this off. Should we look at the Enterprise Library as a place to start? Is REST with ASP.Net MVC2 a better solution than Web Services for a system like this? Will WPF deliver forms re-use or is there something better?

• Java: Copying an exe-file and launching afterwards fails

  - by Philip

  Hi, I want to copy an existing .exe-file from one directory to another and launch it afterwards with Java. Like this: FileIO.copy( new File( sourceFile ), new File( targetFile ) ); System.out.println( "Existing: " + new File( targetFile ).exists() ); System.out.println( "Launching " + targetFile ); String cmd[] = { targetFile }; Process p = Runtime.getRuntime().exec( cmd ); p.waitFor(); System.out.println( "Result: " + p.exitValue() ); The output is like this: Existing: true Launching C:\test\Launcher.new.exe Result: 2 So Java says that the file is valid and existing, but Windows just can't launch the process because it thinks the file is not there. The pathes are absolute and with backslashes. I also have all permissions on the files so I'm allowed to execute them. The Launcher.new.exe is generated by Launch4j, so it's more or less standalone. At least it doesn't depend on DLLs in the same folder. But strange: It works when I copy and launch the notepad.exe. One more strange thing: If I don't copy the file by Java but by hand, the launching also fails with the same error. OS is Vista with SP1. Any clue?
