  • can a webservice load jars during run time

    - by KItis
    I have created a simple web-service using Java. i want to load jars related to web-service during runtime. I have done this task for normal Java application. there what I did was JarFile jar = new JarFile(f.getPath()); final Manifest manifest = jar.getManifest(); final Attributes mattr = manifest.getMainAttributes(); // Read the manifset in jar files and get the Name attribute // whare it specified the class that need to load //for (Object a : mattr.keySet()) { for (Iterator iter = mattr.keySet().iterator(); iter.hasNext();) { Object obj = (Object)iter.next(); if ("ServiceName".equals(obj.toString())) className = mattr.getValue((Name) obj); //System.out.println(className); } /* * Create the jar class loader and use the first argument passed * in from the command line as the jar file to use. */ JarClassLoader jarLoader = new JarClassLoader(f.getPath()); /* Load the class from the jar file and resolve it. */ Class c = jarLoader.loadClass(className, true); My problem is can I put jars that need to be loaded during run time in to separate folder rather than putting in to WEBINF folder. do i have to put jars both in axis and web-application. thanks in advance for any contribution for this question.

    I want to perform asynchronous JavaScript downloads of two files that have dependencies attached to them. function addScript(url) { var script = document.createElement('script'); script.src = url; document.getElementsByTagName('head')[0].appendChild(script); } addScript('http://google.com/gmaps.js'); addScript('http://jquery.com/jquery.js'); function requiresJQuery() { ... } function requiresGmaps() { ... } function requiresBothJQueryGmaps() { ... } // do some work that has no dependencies on either JQuery or Google maps ... // now call a function that requires Gmaps to be loaded if (GmapsIsLoaded) { requiresGmaps(); } // then do something that requires both JQuery & Gmaps (or wait until they are loaded) if (JQueryAndGmapsIsLoaded) { requiresBothJQueryGmaps(); } Question: How can I create an event to indicate when: JQuery is loaded? Google Maps is loaded JQuery & Google Maps are both loaded?

  • Surface Detection in 2d Game?

    - by GamiShini
    I'm working on a 2D Platform game, and I was wondering what's the best (performance-wise) way to implement Surface (Collision) Detection. So far I'm thinking of constructing a list of level objects constructed of a list of lines, and I draw tiles along the lines. ( http://img375.imageshack.us/img375/1704/lines.png ). I'm thinking every object holds the ID of the surface that he walks on, in order to easily manipulate his y position while walking up/downhill. Something like this: //Player/MovableObject class MoveLeft() { this.Position.Y = Helper.GetSurfaceById(this.SurfaceId).GetYWhenXIs(this.Position.X) } So the logic I use to detect "droping/walking on surface" is a simple point (player's lower legs)-touches-line (surface) check (with some safety approximation - let`s say 1-2 pixels over the line). Is this approach OK? I`ve been having difficulty trying to find reading material for this problem, so feel free to drop links/advice.

  • Java Web Application on Tomcat - Displaying a File Uploaded by User

    - by walnutmon
    I need to display uploaded files on a web application, the flow is as follows User uploads file through web UI Validation on image Makes call to imageRepository.store( uploadedImage, user.getSite() ) The user wants the image displayed which adds <img src="${anUploadedImage.getUrl()}"/> but that is where I'm stuck, what can getUrl() do? The simple solution is to put it someplace and let Apache serve the file, but then I can't use the application to ensure that one user isn't modifying the URL to view other users files, which in this case is important

  • getting error as Internal Server error

    - by Rishi2686
    Hi There, When I try to run my site it gives error as Internal Server error, when I refresh the page I get my result properly.The error page looks like this: Internal Server Error The server encountered an internal error or misconfiguration and was unable to complete your request. Please contact the server administrator, [email protected] and inform them of the time the error occurred, and anything you might have done that may have caused the error. More information about this error may be available in the server error log. Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request. I also checked error_log file on my server, it gives error as: [Sat Jun 12 01:21:55 2010] [error] [client 117.195.6.76] File does not exist: /home/rohit25/public_html/test/500.shtml, referer: http://www.test.mysite.com/home.php sometimes error can be; [Sat May 29 19:35:12 2010] [error] [client 97.85.189.208] File does not exist: /home2/carlton/public_html/test/favicon.ico Are there any changes required in configuration file, I also tried to involve this error code in custom error page, it shows error page, which could not resolve this issue.

  • Suggestion on UPnP presentation

    - by Microkernel
    Hi all, I am working on an embedded device (bit higher end in terms of system resources but still an embedded one) which has lot of media content in it. I am trying to make it UPnP complaint and want to be able to control this device using a UPnP complaint control point/companion device like ipad. The step towards this is to be able to present the playlist content to the user. We thought of using HTML5 as a format to use. But as I am a noob in web technologies, I am not sure whats the best way to produce and present rich dynamic web pages. The content thats presented are video/audio listing that device can play and want this listing to be generated using the user's input criteria. So, what would be the best way to generate these dynamic pages which are rich and rendered as HTML5 pages. (looked at XML & XSLT, but there seems to be some limitations in how well one can use XSLT from some rewviews I saw). Thanks Microkernel PS: This may be silly or very basic as I am a embedded systems developer and not even a noob in web technologoes...

  • More efficient comparison of numbers

    - by Pez Cuckow
    I have an array which is part of a small JS game I am working on I need to check (as often as reasonable) that each of the elements in the array haven't left the "stage" or "playground", so I can remove them and save the script load I have coded the below and was wondering if anyone knew a faster/more efficient way to calculate this. This is run every 50ms (it deals with the movement). Where bots[i][1] is movement in X and bots[i][2] is movement in Y (mutually exclusive). for (var i in bots) { var left = parseInt($("#" + i).css("left")); var top = parseInt($("#" + i).css("top")); var nextleft = left + bots[i][1]; var nexttop = top + bots[i][2]; if(bots[i][1]>0&&nextleft>=PLAYGROUND_WIDTH) { remove_bot(i); } else if(bots[i][1]<0&&nextleft<=-GRID_SIZE) { remove_bot(i); } else if(bots[i][2]>0&&nexttop>=PLAYGROUND_HEIGHT) { remove_bot(i); } else if(bots[i][2]<0&&nexttop<=-GRID_SIZE) { remove_bot(i); } else { //alert(nextleft + ":" + nexttop); $("#" + i).css("left", ""+(nextleft)+"px"); $("#" + i).css("top", ""+(nexttop)+"px"); } } On a similar note the remove_bot(i); function is as below, is this correct (I can't splice as it changes all the ID's of the elements in the array. function remove_bot(i) { $("#" + i).remove(); bots[i] = false; } Many thanks for any advice given!

  • Is Webhooks a style/pattern or a specification?

    - by Emilio
    I've been reading about Webhooks and I'm trying to determine if it's a specification vs a style/pattern. By "specification" I mean that the implementation details, e.g. headers, payload and so on are well defined. By "style" or "pattern" I mean in the sense that REST is a style (as opposed to a spec) or a pattern which describes usage but doesn't define implementation details. From what I see, Webhooks is a style/pattern. That the event(s) which triggers the http callbacks are generated however the developer wants, and that the http callbacks have no specific implementation requirements except to be an http post. Is this correct?

  • Is this a legitimate implementation of a 'remember me' function for my web app?

    - by user246114
    Hi, I'm trying to add a "remember me" feature to my web app to let a user stay logged in between browser restarts. I think I got the bulk of it. I'm using google app engine for the backend which lets me use java servlets. Here is some pseudo-code to demo: public class MyServlet { public void handleRequest() { if (getThreadLocalRequest().getSession().getAttribute("user") != null) { // User already has session running for them. } else { // No session, but check if they chose 'remember me' during // their initial login, if so we can have them 'auto log in' // now. Cookie[] cookies = getThreadLocalRequest().getCookies(); if (cookies.find("rememberMePlz").exists()) { // The value of this cookie is the cookie id, which is a // unique string that is in no way based upon the user's // name/email/id, and is hard to randomly generate. String cookieid = cookies.find("rememberMePlz").value(); // Get the user object associated with this cookie id from // the data store, would probably be a two-step process like: // // select * from cookies where cookieid = 'cookieid'; // select * from users where userid = 'userid fetched from above select'; User user = DataStore.getUserByCookieId(cookieid); if (user != null) { // Start session for them. getThreadLocalRequest().getSession() .setAttribute("user", user); } else { // Either couldn't find a matching cookie with the // supplied id, or maybe we expired the cookie on // our side or blocked it. } } } } } // On first login, if user wanted us to remember them, we'd generate // an instance of this object for them in the data store. We send the // cookieid value down to the client and they persist it on their side // in the "rememberMePlz" cookie. public class CookieLong { private String mCookieId; private String mUserId; private long mExpirationDate; } Alright, this all makes sense. The only frightening thing is what happens if someone finds out the value of the cookie? A malicious individual could set that cookie in their browser and access my site, and essentially be logged in as the user associated with it! On the same note, I guess this is why the cookie ids must be difficult to randomly generate, because a malicious user doesn't have to steal someone's cookie - they could just randomly assign cookie values and start logging in as whichever user happens to be associated with that cookie, if any, right? Scary stuff, I feel like I should at least include the username in the client cookie such that when it presents itself to the server, I won't auto-login unless the username+cookieid match in the DataStore. Any comments would be great, I'm new to this and trying to figure out a best practice. I'm not writing a site which contains any sensitive personal information, but I'd like to minimize any potential for abuse all the same, Thanks

  • Why function callback of Connection is not handled with Yahoo UI ?

    - by quilovnic
    I use Yahoo UI with Grails (so grailsui) and I try to upload a file with Ajax and get a JSON response from the server : The response is correctly returned by my controller but a popup is displayed to save the file but it's not a file it's a JSON result. My Yahoo Code is : callback = { success: function(o){alert('success');}, failure: function(o){alert('failure');} } YAHOO.util.Connect.asyncRequest('POST', '/my/url', callback); The http response is the JSON result. What's hell is wrong ? Why does I have dialog box to download the file ? Thanks a lot.

  • distributing R package with optional S4 syntax sugar

    - by mariotomo
    I've written a small package for logging, I'm distributing it through r-forge, recently I received some very interesting feedback on how to make it easier to use, but this functionality is based on stuff (setRefClass) that was added to R in 2.12. I'd like to keep distributing the package also for R-2.9, so I'm looking for a way to include or exclude the S4 syntactical sugar automatically, and include it when the library is loaded on a R = 2.12 system. one other option I see, that is to write a small S4 package that needs 2.12, imports the simpler logging package and exports the syntactically sugared interface... I don't like it too much, as I'd need to choose a different name for the S4 package.

  • Self-signed ceritificates for many users/browsers/sites

    - by Demiurg
    Here is my problem - I have a lot of users using different browsers accessing many internal web sites using https. I can create my own Certificate Authority, than create a certificate for each server and after that have all the users import it. Obviously, it cannot work in reality - there are too many users and too many sites, and some sites will be added in the future. I'm looking for a way to automate this. Is there a way to create a certificate so that all major browsers (IE, FF, Opera, Chrome and Safari) would trust it for all servers ? If so, what is the best way to install it automatically in all major browsers ?

  • Methods of pulling data from a database

    - by kingrichard2005
    I'm getting ready to start a C# web application project and just wanted some opinions regarding pulling data from a database. As far as I can tell, I can either use C# code to access the database from the code behind (i.e. LINQ) of my web app or I can call a stored procedure that will collect all the data and then read it with a few lines of code in my code behind. I'm curious to know which of these two approaches, or any other approach, would be the most efficient, elegant, future proof and easiest to test.
