• I'm having a problem redeploying an applications using Drools and Tomcat 6

  - by FrankL

  I have a spring application that uses JBoss Drools 5. It works fine except for when I attempt to redeploy (i.e. hot deploy) the application after I make a change during development. It appears that tomcat keeps a lock on 2 drools jar files, drools-compiler-5.0.1.jar and drools-core-5.0.1.jar. Since they can't be deleted the new war file does not get deployed. If my application does not make any Drools logic calls, then the hot deploy works. Does anyone have any ideas?

• Parsing/executing C# code in C++ (on Linux)?

  - by Stick it to THE MAN

  I want to be able to add scripting functionality to my application. One of the language bindings I am considering is C# (and possibly VB.Net). The challenge is this: My application is developed in C++ My application runs on Linux I am aware of Mono, but I dont know (as yet), what is required to allow my C++ appliaction (running on linux), to be scriptable with .Net languages. Is this feasible? Am I crazy for even thinking of doing this? If I'm not crazy, can anyone provide some guidelines on how to go about implementing this? Help, tips, ideas, suggestions anyone?

• Visual Studio: Link executable

  - by smerlin

  Lets say I have: a static library project called "LIB" a application project called "LIBAPP" a application project called "APP" a application project called "APPTEST" When i add "LIB" to LIBAPP Project Dependencies, Visual Studio automatically links "LIBAPP" against LIB. But when i add APP to APPTEST Project Dependencies, it doesnt. Since i am doing unit tests of APP's classes in APPTEST, i have to link against APP, therefore i am currently manually linking against all *.obj files of APP (hundreds...) Since i have to change the link targets of APPTEST everytime i add or remove a *.cpp file from APP, this isnt a nice solution. So is there a way to force Visual Studio to do this for me automatically, like it does when adding a static library Project Dependency ?

• Communication via internet in Java

  - by Stuart

  What I mean is like servers on video games. You can run an application and it will set up a server on your computer with an IP and a port. For example, how would you make an application where one host application sets up a thing where it has an IP and a port, and another computer that has access to the internet as well can type in the IP and port and it would be able to communicate with the host? I mean simple communication, like sending a boolean or String. And would there be any security problems that would be needed to fix?

• Problem with Juggernaut and transparent wmode in Adobe AIR

  - by vortexmk

  Hi, I am trying to use juggernaut in Adobe AIR application, however the big issue with this is that the juggernaut flash file should have wmode parameter set to 'transparent'. This is a bit of a problem for juggernaut because it seems that it doesn't work with that parameter included. The interesting part is that it is working under Linux on all browsers and in air application, but on Windows it's working only with Safari all other browsers including the AIR application are not even connecting to the juggernaut server. So the question is, what is the cause of this and if anyone had similar problem I would be interested to hear about solutions or workarounds. Thanks, Peco

Is it possible?

• How does Windows' 'Open with' work?

  - by Frederick

  I was under the impression that when you double click a file (or choose 'Open With' from the right click menu), Windows simply calls the application with the filename as the parameter. Something like this: C: App.exe file.abc However, I just double clicked an .xls file and then checked the PEB of the Excel instance that sprang up. To my surprise the commandline did not contain the filename as a parameter. So that set me wondering. What exactly is mechanism Windows uses to have a file opened by a relevant application? Is there a special API that each application that supports such facility must expose?

• How to determine JAVA_HOME on Debian/Ubuntu?

  - by Witek

  On Ubuntu it is possible to have multiple JVMs at the same time. The default one is selected with update-alternatives. But this does not set the JAVA_HOME environment variable, due to a debian policy. I am writing a launcher script (bash), which starts a java application. This java application needs the JAVA_HOME environment variable. So how to get the path of the JVM which is currently selected by update-alternatives?

• MS SQL server: Single or multiple instances?

  - by Hugo Riley

  How costly (CPU or memory wise) is it to have multiple instances of SQL server 2005 instead of only one instance with prefixed databases? A company have three application providers. They each will install one application and they each require two or three databases. Should they all use the same instance or should every provider use it's own named instance? Is there any strong reason for one or other setup?

• Pros and Cons of Access Data Project (MS Access front end with SQL Server Backend)

  - by webworm

  I have been tasked with moving an existing MS Access application (mdb) over to an Access Data Project (adp). Basically the Access forms will remain the same but the data will be migrated over to SQL Server. I am not too familiar with Access Data Projects so I was hoping I could get some opinions on the pros and cons of using them. My first thought was to convert this to a web application or even a Winform application, however I really wanted to perform due dilligence in looking at Access Data Projects before making a decision. Thanks for any assistance.

• How to redirect external web request to localhost's testing server

  - by Ivan Monteiro

  Some web services calls my web application(www.myapplication.com/external_update_handler). I need to test those requests locally, so I'd like to know your opinions about how can I "redirect" those requests to my localhost dev machine(that is outside of my web aplication domain) so I can debug. Probably it's needed a service/server to get those external requests and a desktop application that sends it to localhost:5555/external_update_handler, but I have no idea where to start and simpler options.

• Are there any was to link my program with Wine-compiled part?

  - by seas

  I am trying to use windows dll functionality in Linux. My current solution is a compilation of a separate wine application, that uses dll and transfer requests/responses between dll and main application over IPC. This works, but is a real overhead comparing to a simple dll calls. I see that wine-compiled program usually is a bootstrapping-script and some .so, which (according to file utility) is normal linux dynamically linked library. Are there any way to link that .so directly to my application? Are there any manual?

  Hi All I am trying to implement a feature. But I've never had anything to do with "Web Services" before, other than using them. I have a desktop application, and I want that application to be able to sort of "post" some information (i.e. email address, username, user-selected options (just plain text) etc) to an application or "web service" on my ASP.NET web server. Can somebody please guide me in the right direction? How would I accomplish this? Thank you :) Jason

• How can I load scripts, styles and images from a non-URL source?

  - by Jen

  I am integrating WebKit (via Qt) into an application. Instead of having WebKit retrieve scripts, CSS files and images via URLs, I want my application to provide them (e.g. retrieved from a database). For example, a "regular" web page may contain this tag: <IMG src="photos/album1/123456.jpg"> Instead of WebKit fetching this image from a server or the file system, I would prefer some kind of callback that allows my application to provide this image. How can I accomplish this?

• Zend - Deny access to CSS, JS, Image files

  - by Vincent

  All, I have the following Zend application structure: helloworld - application - configs - controllers - models - layouts - include - library - public - design -- css -- site.css -- js -- global.js -- images -- siteheader.gif -- sitefooter.gif - .htaccess - index.php My .htaccess file in public folder looks like this: Options -MultiViews RewriteEngine On RewriteCond %{REQUEST_FILENAME} -s [OR] RewriteCond %{REQUEST_FILENAME} -l [OR] RewriteCond %{REQUEST_FILENAME} -d RewriteRule ^.*$ - [NC,L] RewriteRule ^.*$ index.php [NC,L] My document root points to the "public" folder. Currently, if the user visits a directory level URL, (Ex: http://localhost/design or localhost/css) , my .htaccess file above make sure to show him the "Access Forbidden" page. But if he visits the file level URL, (Ex: http://localhost/design/css/site.css), it shows him the CSS file or the js file or PHP file.. How can I make sure to lock file level access for the above file types, if accessed directly from the URL? Since my application is JS intensive, I want to protect it from users looking at it. Thanks

  - by gln

  I wrote an application in c++ which send data over tcp connection to several machines.as part of the protocol I use in my application, the other side sends hearbeat messages from time to time, then I know that the connection is still alive. now, I want this application to work on 100 machines or more at the same time. but, I see that sometimes I don't get these heartbeat messages although they sent: I see in wireshark that the packet arrived, then my OS doesn't ack on this message, so there are some retransmit without any ack from my OS. if I look in the window size property - I saw that there is no issue in this part. what can be the root cause for this behavior? it is something in my code that I should change? this is my select code: int res = select(fdCount, &readFds, NULL, NULL, NULL ); I'm using server 2008 r2. Please help me! thanks

• UINavigation controller problem

  - by VansFannel

  Hello. I'm developing an iPhone application and I'm trying to do this: I want an application with tree views. The view shown first, doesn't have a navigation bar. If the user tap on a button, I need to open the second view with a navigation bar and a table view. The user can also add new items to the table view. If the user do so, the application will show the third view where the user can add fields (this view has also a navigation bar). It may seem simple, but for me it is not. I don't know how to use the UINavigationController and have not found yet a similar example for what I do (paragraph translated by google). UPDATE I don't know how where to put UINavigationController. How can I do that? Can I use a UIViewController to call a UINavigationController? Thank you.
