• fastest public web app framework for quick DB apps?

  - by Steve Eisner

  I'd like to pick up a new tech for my toolbox - something for rapid prototyping of web apps. Brief requirements: public access (not hosted on my machine) - like Google's appengine, etc no tricky configuration necessary to build a simple web app host DB access (small storage provided) including some kind of SQLish query language easy front end HTML templating ability to access as a JSON service C# or Java,PHP or Python - or a fun new language to learn is OK free! An example app, very simple: render an AJAXy editable (add/delete/edit/drag) list of rich-data list items via some template language, so I can quickly mock up a UI for a client. ie. I can do most of the work client-side, but need convenient back end to handle the permanent storage. (In fact I suppose it doesn't even need HTML templating if I can directly access a DB via AJAX calls.) I realize this is a bit vague but am wondering if anyone has recommendations. A Rails host might be best for this (but probably not free) or maybe App Engine, or some other choice I'm not aware of? I've been doing everything with heavyweight servers (ASP.NET etc) for so long that I'm just not up on the latest... Thanks - I'll follow up on comments if this isn't clear enough :)

• Reload a UITable on the fly when editing a UITextField inside one of the cells

  - by Saze

  I have a UITable containing some customs UITableCells. Those cells contain a few UILabels and a UITextField. The datasource of the table comes from a main controller's property. (This controller is also the delegate and the dataSource for the table). Here's a simplified screenshot of the UI: Now, I need to update "on the fly" the content of all the UILabels when the user edits one of the UITextFields. To do so, at the I am listening to the "Editing Changed" event at the UITextField level. This triggers the following action: - (IBAction) editChangeHandler: (id) sender { MyAppDelegate *delegate = [[UIApplication sharedApplication] delegate]; [[delegate.viewController.myDataSourceArray objectAtIndex:self.rowIndex] setANumber: [theTextField.text intValue]]; [delegate.viewController reloadRows]; } The reloadRows method in the viewController is as such: - (void) reloadRows { NSLog(@"called reloadRows"); //perform some calculations on the data source objects here... [theUITable reloadData]; } My problem here is that whenever the user changes the value in the field, the reloadRows method is successfully called, so is apparently the reloadData but it also causes the keyboard to be dismissed. So in the end, the user can only touch one key when editing the TextField before the keyboard is dismissed and the table reloaded. Does anybody knows a solution to this or have experienced the same issue?

• Is there a point to have multiple VS projects for an ASP.NET MVC application?

  - by mare

  I'm developing MVC application where I currently have 3 projects in solution. Core (it is supposed to be for Repositories, Business Classes, Models, HttpModules, HttpFilters, Settings, etc.) Data access (Data provider, for instance SqlDataProvider for working with SQL Server datastore - implements Repository interfaces, XmlDataProvider - also implements Repository interfaces but for local XML files as datastore) ASP.NET MVC project (all the typical stuff, UI, controllers, content, scripts, resources and helpers). I have no Models in my ASP.NET MVC project. I've just run into a problem because of that coz I want to use the new DataAnnotation feature in MVC 2 on my Bussiness class, which are, as said in Core, however I have I want to be able to localize the error messages. This where my problem starts. I cannot use my Resources from MVC project in Core. The MVC project references Core and it cannot be vice-versa. My options as I see them are: 1) Move Resources out but this would require correcting a whole bunch of Views and Controllers where I reference them, 2) Make a complete restructure of my app What are your thoughts on this? Also, Should I just move everything business related into Models folder in MVC project?? Does it even make any sense to have it structured like that, because we can just make subfolders for everything under MVC project? The whole Core library is not intended to ever be used for anything else, so there actually no point of compiling it to a separate DLL. Suggestions appreciated.

• Can it be done?

  - by bzarah

  We are in design phase of a project whose goal is replatforming an ASP classic application to ASP.Net 4.0. The system needs to be entirely web based. There are several new requirements for the new system that make this a challenging project: The system needs to be database independent. It must, at version 1.0, support MS SQL Server, Oracle, MySQL, Postgres and DB2. The system must be able to allow easy reporting from the database by third party reporting packages. The system must allow an administrative end user to create their own tables in the database through the web based interface. The system must allow an administrative end user to design/configure a user interface (web based) where they can select tables and fields in the system (either our system's core tables or their own custom tables created in #3) The system must allow an administrative end user to create and maintain relationships between these custom created tables, and also between these tables and our system's core tables. The system must allow an administrative end user to create business rules that will enforce validation, show/hide UI elements, block certain actions based on the identity of specific users, specific user groups or privileges. Essentially it's a system that has some core ticket tracking functionality, but allows the end user to extend the interface, business rules and the database. Is this possible to build in a .Net, Web based environment? If so, what do you think the level of effort would be to get this done? We are currently a 6 person shop, with 2.5 full time developers.

• (Python/Pyramid) Better ways to have standard list/form editors?

  - by badcat

  I'm working on a number of Pyramid (former Pylons) projects, and often I have the need to display a list of some content (let's say user accounts, log entries or simply some other data). A user should be able to paginate through the list, click on a row and get a form where he/she can edit the contents of that row. Right now I'm always re-inventing the wheel by having Mako templates which use webhelpers for the pagination, Jquery UI for providing a dialog and I craft the editor form and AJAX requests on the client and server side by hand. As you may know, this eats up painfully much time. So what I'm wondering is: Is there a better way of providing lists, editor dialog and server/client communication about this, without having to re-invent the wheel every time? I heard Django takes off a big load of that by providing user accounts and other stuff out of the box; but in my case it's not just about user accounts, it can be any kind of data that is stored on the server-side in a SQL database, which should be able to be edited by a user. Thanks in advance!

• How to handle exceptions from an image-generating Servlet?

  - by ssahmed555

  I have a simple (Servlet, JSP, and JSTL) web app whose main functionality is displaying images retrieved from a back-end server. The controller servlet forwards the user to a JSP that in turn uses another Servlet to display the resulting image on that same JSP. Further down, the JSP has a line similar to: <a href="<c:out value='${imageURL}'/>"><img src="<c:out value='${imageURL}'/>" alt="image view" border="1"></a> which invokes a GET request on the image-generating servlet causing it to generate the image. My question is: how do I handle Exceptions thrown by this image-generating servlet? I already have an error page defined (in web.xml) to handle ServletException within my web app but this doesn't work for this image-generating Servlet, and results in the following errors showing up in my Tomcat server logs: SEVERE: Exception Processing ErrorPage[exceptionType=javax.servlet.ServletException, location=/WEB-INF/ExceptionPage.jsp] java.lang.IllegalStateException: Cannot reset buffer after response has been committed What's my recourse in this situation? I'd like to be able to handle Exceptions thrown from this image-generating Servlet, and display some error on the main UI or forward the user to another error page.

• Simulate Golf Game Strategy

  - by Mitchel Sellers

  I am working on what at best could be considered a "primitive" golf game, where after a certain bit of randomness is introduced I need to play out a hole of golf. The hole is static and I am not concerned about the UI aspect as I just have to draw a line on a graphic of the hole after the ball has been hit showing where it traveled. I'm looking for input on thoughts of how to manage the "logic" side of the puzzle, below are some of my thoughts on the matter, input, suggestions, or references are greatly appreciated. Map out the hole into an array with a specific amount of precision, noting the type of surface: out of bounds, fairway, rough, green, sand, water, and most important the hole. Map out "regions" and if the ball is contained inside one of these regions setup parameters for "maximum" angle of departure. (For example the first part of the hole the shot must be between certain angles Using the current placement of the ball, and the region contained in #2, define a routine to randomly select the shooting angle, and power then move the ball, adjust the trajectory and move again. I know this isn't the "most elegant" solution, but in reality, we are looking for a quick and dirty solution, as I just have to do this a few times, set it and forget it afterward. From a languages perspective I'll be using ASP.NET and C# to get this done.

• autoreload webpage on new release

  - by user3726562

  I have a website in PHP which is completely ajax-based. There is an index.php, but a part from it, all the other page are never rendered directly into the browser. Instead, all the post and get request are done tfrom javascript through ajax. So basically, if you go to /contact.php you will not see anything. All the pages are rendered inside index.php. So, there are a lot of people that use this page that are not very good in using the web. Asking them to "refresh" the page makes them to wonder what we are talking about. Unfortunately. The biggest issue happens when we do a new release. Especially the javascript code (but not only) can be the old one in a client's webpage as they maybe havent refreshed the page for some week (lol). S I do an svn-update and the new code is on the server. I just refresh my page and see the new features. However, the poor guys that dont really know how to make a refresh, will not see anything. I have added a big button on the page with the text "refresh". Which makes a location.reload. Hopefully this can help a few of them. But my question is: how to "force" the browser to reload itself when a new svn-version has been released? Hopefully in a simple way, without needing some node.js, javascript timer or stuff like that. It is also quite important to not refresh the page when the user is doing something with the page (maybe writing a mail in the UI, and then suddenly the page get refreshed: not so good).

• How to display controllers with proper aligning in iPhone screen ?

  - by chatcja

  I have a issue of displaying information in iPhone screen. Case is as follows. I crated a view-based application in Xcode name as myView. Then open myViewViewController.xib interface builder, change back groung color and added label at top-let (0, 0) of the view. Then I add new file named as myView2ViewController, which is subclass of UIViewController and corresponding XIB also generated. Open myView2ViewController in IB and added a label at top-left as previous. Also changed the background color. In the "applicationDidFinishLaunching" of AppDeligate do following myView2ViewController *mView = [[myView2ViewController alloc] initWithNibName:@"myView2ViewController" bundle:nil]; [window addSubview:mView.view]; When I run the application, it is shown as upper part of the Label is sheared. It seems as whole UI has been moved 20 px upper (Because, there is a horizontal space in the bottom). I guess this is due to some positioning. But still I could not found any way to fix it. Hope somebody will help me to identify this issue !!

• NSView only redraws on breakpoint

  - by Jacopo

  I have a custom view inside a NSPopover. It should change according to user input and it does the first time the user interact with it but it fails to redraw the following times. I have tried to put an NSLog inside the -drawRect: method and it doesn't get called during normal execution. When I try to debug and put a breakpoint inside the method it gets called normally and the app works as it should. I explicitly call the view -setNeedsDisplay: method every time I need it to redraw. I don't understand why it should make a difference. Here is the code that update the status of the view. These methods are part of the NSTextField delegate method -textDidChange: and I checked that these get called every time the user type something in the textfield associated with popover. [tokenCloud tokensToHighlight:[NSArray arrayWithObject:completeSuggestionString]]; tokenCloud.tokens = filteredTokens; [tokenCloud setNeedsDisplay:YES]; The views is a series of recessed button. The first line update the status of all the buttons in the popover and the second add or delete buttons. They both work properly because the first time they are called the view is update properly. I have also checked that both the status of the buttons in tokenCloud and its property tokens are updated correctly. The problem is that the NSView subclass, tokenCloud, doesn't redraw so the changes are not reflected in the UI the second time. Here is the draw method of the view: - (void)drawRect:(NSRect)rect { [self recalculateButtonLocations]; NSLog(@"Redrawn"); } Again this method gets called normally every time I update the view if I place a breakpoint in [self recalculateButtonLocations];. If instead I let the app run normally nothing gets logged in the console the second time I update the view. Same thing if I include the NSLog in the recalculateButtonLocations method, nothing gets logged the second time meaning that the method is not called.

• Suggestions on Working with this Inherited Generic Method

  - by blu

  We have inherited a project that is a wrapper around a section of the core business model. There is one method that takes a generic, finds items matching that type from a member and then returns a list of that type. public List<T> GetFoos<T>() { List<IFoo> matches = Foos.FindAll( f => f.GetType() == typeof(T) ); List<T> resultList = new List<T>(); foreach (var match in matches) { resultList.Add((T)obj); } } Foos can hold the same object cast into various classes in inheritance hierarchy to aggregate totals differently for different UI presentations. There are 20+ different types of descendants that can be returned by GetFoos. The existing code basically has a big switch statement copied and pasted throughout the code. The code in each section calls GetFoos with its corresponding type. We are currently refactoring that into one consolidated area, but as we are doing that we are looking at other ways to work with this method. One thought was to use reflection to pass in the type, and that worked great until we realized the Invoke returned an object, and that it needed to be cast somehow to the List <T>. Another was to just use the switch statement until 4.0 and then use the dynamic language options. We welcome any alternate thoughts on how we can work with this method. I have left the code pretty brief, but if you'd like to know any additional details please just ask.

• How can I create dynamically updated views in a tab bar view, based on settings selection?

  - by Diggers

  Hi all, Noob question.... I've created a Tab Bar application. It has four tabs and works fine. Each view is created with a XIB and is effectively static. Each view takes user input and responds on screen. What I need to be able to do is change the input options the user have - in effect remove some UITextFields dependant upon which option the user selects in settings. I've created root.plist and created settings no problem i've also created additional XIBS for the altered UI, but what I don't know how to do, is call these into the tab view controller on demand. Effectively tab one has 3 possible views, tab two 3 possible views etc. But I only want the one that's relevant for the users settings selction to be displayed? Make sense? For reference, if we call the different views - UIInputViewA1, ...A2,....A3 UIInputViewB1,....B2....B3 etc. Hope someone can help, been trawling the net for nights trying to get my head round this. Beggining iPhone Development Bible doesn't help either. If you need any more info, please shout. Cheers Paul.

• Writing all the html of a document with jquery instead of in the page body?

  - by Robert

  I'm a UI person currently working on a web application, where most of the people I work with are back end developers. I'm currently at a disagreement with them about whether or not the above is a prudent thing to do. This application doe use quite a bit of JavaScript, and wouldn't even work without it unfortunately. This being the case, One of the back end developers that I'm working with is claiming that pages could and even SHOULD be build completely with JavaScript or jquery. This caught me completely off guard. We're talking about div tags, lists, background images and text here. I'm trying to explain to him that this isn't the right way to do things at all, and from a best practices perspective: content(html) should be separate from presentation(css), and behavior(script etc.). I know that it's possible to write html in jquery, although I haven't done it, but am I wrong in my thinking that this isn't the way things should be done. Is it even possible to write ALL the code with jquery? would love to hear any thoughts either way, as I will be discussing this with him again tomorrow.

• Cannot reach reach jQuery (in parent document ) from IFRAME

  - by Michael Joyner

  I have written a backup program for SugarCRM. My program sets a iframe to src=BACKUP.PHP My backup program sends updates to parent window with: echo "<script type='text/javascript'>parent.document.getElementById('file_size').value='".fileSize2human(filesize($_SESSION['archive_file_name']))."';parent.document.getElementById('file_count').value=".$_SESSION['archive_file_count'].";parent.document.getElementById('description').innerHTML += '".$log_entry."\\r\\n';parent.document.getElementById('description').scrollTop = parent.document.getElementById('description').scrollHeight;</script>"; echo str_repeat( ' ', 4096); flush(); ob_flush(); I have added a JQUERY UI PROGRESS BAR and I need to know how I update the progress bar on the parent window.

• WordPress > Cannot get custom meta settings to change once set...

  - by Scott B

  The script below adds a custom meta box to the WordPress page editor interface. It lists two specific categories, "noindex" and "nofollow", which my custom theme automatically installs when the theme is activated. It works fine for selecting and assigning the categories to the page. However, if the user unchecks either of them, the settings do not stick. Once selected, they cannot be removed from the page, regardless if they are unchecked when the page is saved. <?php function my_post_categories_meta_box() { add_meta_box('categorydiv', __('Page Options'), 'post_categories_meta_box_modified', 'page', 'side', 'core'); } function post_categories_meta_box_modified($post) { $noindexCat = get_cat_ID('noindex'); $nofollowCat = get_cat_ID('nofollow'); if(in_category("noindex")){ $noindexChecked = " checked='checked'";} if(in_category("nofollow")){ $nofollowChecked = " checked='checked'";} ?> <div id="categories-all" class="ui-tabs-panel"> <ul id="categorychecklist" class="list:category categorychecklist form-no-clear"> <li id='category-<?php echo $noindexCat ?>' class="popular-category"><label class="selectit"><input value="<?php echo $noindexCat ?>" type="checkbox" name="post_category[]" id="in-category-<?php echo $noindexCat ?>"<?php echo $noindexChecked ?> /> noindex</label></li> <li id='category-<?php echo $nofollowCat ?>' class="popular-category"><label class="selectit"><input value="<?php echo $nofollowCat ?>" type="checkbox" name="post_category[]" id="in-category-<?php echo $nofollowCat ?>"<?php echo $nofollowChecked ?> /> nofollow</label></li> </ul> </div> <?php } add_action('admin_menu', 'my_post_categories_meta_box'); ?>

• Zoom in Java Swing application

  - by Shirky

  Hi there, I am looking for ways to zoom in a Java Swing application. That means that I would like to resize all components in a given JPanel by a given factor as if I would take an screenshot of the UI and just applied an "Image scale" operation. The font size as well as the size of checkboxes, textboxes, cursors etc. has to be adjusted. It is possible to scale a component by applying transforms to a graphics object: protected Graphics getComponentGraphics(Graphics g) { Graphics2D g2d=(Graphics2D)g; g2d.scale(2, 2); return super.getComponentGraphics(g2d); } That works as long as you don't care about self-updating components. If you have a textbox in your application this approach ceases to work since the textbox updates itself every second to show the (blinking) cursor. And since it doesn't use the modified graphics object this time the component appears at the old location. Is there a possibility to change a components graphics object permanently? There is also a problem with the mouse click event handlers. The other possibility would be to resize all child components of the JPanel (setPreferredSize) to a new size. That doesn't work for checkboxes since the displayed picture of the checkbox doesn't change its size. I also thought of programming my own layout manager but I don't think that this will work since layout managers only change the position (and size) of objects but are not able to zoom into checkboxes (see previous paragraph). Or am I wrong with this hypothesis? Do you have any ideas how one could achieve a zoomable Swing GUI without programming custom components? I looked for rotatable user interfaces because the problem seems familiar but I also didn't find any satisfying solution to this problem. Thanks for your help, Chris

• Update MySQl table onDrop?

  - by dougvt

  Hi all. I am writing a PHP/MySQL application (using CodeIgniter) that uses some jQuery functionality for dragging table rows. I have a table in which the user can drag rows to the desired order (kind of a queue for which I need to preserve the rank of each row). I've been trying to figure out how to (and whether I should) update the database each time the user drops a row, in order to simplify the UI and avoid a "Save" button. I have the jQuery working and can send a serialized list back to the server onDrop, but is it good design practice to run an update query this often? The table will usually have 30-40 rows max, but if the user drags row 1 far down the list, then potentially all the rows would need to be updated to update the rank field. I've been wondering whether to send a giant query to the server, to loop through the rows in PHP and update each row with its own Update query, to send a small serialized list to a stored procedure to let the server do all the work, or perhaps a better method I haven't considered. I've read that stored procedures in MySQL are not very efficient and use a separate process for each call. Any advice as to the right solution here? Thanks very much for your help!

• How to delay program for a certain number of milliseconds, or until a key is pressed?

  - by Jack

  I need to delay my program's execution for a specified number of milliseconds, but also want the user to be able to escape the wait when a key is pressed. If no key is pressed the program should wait for the specified number of milliseconds. I have been using Thread.Sleep to halt the program (which in the context of my program I think is ok as the UI is set to minimise during the execution of the main method). I have thought about doing something like this: while(GetAsyncKeyState(System.Windows.Forms.Keys.Escape) == 0 || waitTime > totalWait) { Thread.Sleep(100); waitTime += 100; } As Thread.Sleep will wait until at least the time specified before waking the thread up, there will obviously be a large unwanted extra delay as it is scaled up in the while loop. Is there some sort of method that will sleep for a specified amount of time but only while a condition holds true? Or is the above example above the "correct" way to do it but to use a more accurate Sleep method? If so what method can I use? Thanks in advance for your help.

• How do I unbind another jQuery function on .click()?

  - by Mike Barwick

  I have this script that run to fix my menu bar to the browser on scroll. Nothing really needs to change here (works as it should). However, you may need it... var div = $('#wizMenuWrap'); var editor = $('#main_wrapper'); var start = $(div).offset().top; $(function fixedPackage(){ $.event.add(window, "scroll", function() { var p = $(window).scrollTop(); $(div).css('position',((p)>start) ? 'fixed' : 'static'); $(div).css('top',((p)>start) ? '0px' : ''); //Adds TOP margin to #main_wrapper (required) $(editor).css('position',((p)>start) ? 'relative' : 'static'); $(editor).css('top',((p)>start) ? '88px' : ''); }); }); Now for the issue at hand. I have another script function that calls a modal pop-up (which again works as it should). However, it's not slick from a UI perspective when I scroll the page when the modals open. So I want to disable the script above when the modal script below is called. In other words, when I click to open the modal pop-up, the script above shouldn't work. $(function () { var setUp = $('.setupButton'); // SHOWS SPECIFIED VIEW $(setUp).click(function () { $('#setupPanel').modal('show'); //PREVENTS PACKAGE SELECT FIXED POSITION ON SCROLL $(setUp).unbind('click',fixedPackage); }); }) As you can see above, I tried to unbind the scroll function (the first code snippet), but this is not correct. These two scripts are in two separate js libraries.

• Returning a Value from a jQuery Dialog Button Instead of Running a Function

  - by kamera

  I'm working on an admin UI and I can't wrap my head around how to get a specific kind of modal behaviour. I'm using jQuery. I already have a system for modal dialogs in place, where an openModal(settings) function opens a modal. Based on the settings, it will show/hide or sometimes inject various dialogs. I also have a generic confirmation dialog and this is the one I'm not sure how to make work. The layout is simple: <div id="confirmation-dialog"> <h2>Are you sure?</h2> <button class="button.yes">Yes</button> <button class="button.no">No</button> </div> I could just hard-code each button to do what I need it to do but I would like this to be more generic. Ideally, I would like it to function like this: (I know this doesn't work) function deleteImportantThing() { if (confirmThis() == true) { // Delete the thing } else { // Do nothing, close dialog } } function confirmThis() { openModal({kind: "confirm"}); // Check which button is clicked, then return true or false } I guess I just don't know enough JavaScript to get this to work, or to even figure out where to look. Any advice? I know there are modal dialog plug-ins out there but I'd have to change how the rest of my modals work to integrate them, and I'd like to do this myself if at all possible.

• How to structure Javascript programs in complex web applications?

  - by mixedpickles

  Hi there. I have a problem, which is not easily described. I'm writing a web application that makes heavy usage of jquery and ajax calls. Now I don't have experience in designing the architecture for javascript programms, but I realize that my program has not a good structure. I think I have to many identifiers referring to the same (at least more or less) thing. Let's have an exemplary look at an arbitrary UI widget: The eventhandlers use DOM elements as parameters. The DOM element represents a widget in the browser. A lot of times I use jQuery objects (I think they are basically a wrapper around DOM elements) to do something with the widget. Sometimes they are used transiently, sometimes they are stored in a variable for later purposes. The ajax function calls use strings identifiers for these widgets. They are processed server side. Beside that I have a widget class whose instances represents a widget. It is instantiated through the new operator. Now I have somehow four different object identifiers for the same thing, which needs to be kept in sync until the page is loaded anew. This seems not to be a good thing. Any advice?

• Problems With SWT on Mac

  - by Jav

  I've got a java project that uses an SWT UI and I'm having trouble deploying it on any Mac OS X computers. The program itself works perfectly on Windows when it is either run from within Eclipse or from a jar file. On Mac, the program also works fine in Eclipse, but when I try to run it from a jar file, I get the following error: 2010-04-30 13:33:04.564 java[17825:41b] *** _NSAutoreleaseNoPool(): Object 0x10b9b0 of class NSCFString autoreleased with no pool in place - just leaking Stack: (0x944acf4f 0x943b9432 0x678fb79 0x35a19b1 0x359ba7f) 2010-04-30 13:33:04.566 java[17825:41b] *** _NSAutoreleaseNoPool(): Object 0x115ef0 of class NSCFNumber autoreleased with no pool in place - just leaking Stack: (0x944acf4f 0x943b9432 0x678a0b0 0x35a19b1 0x359ba7f) 2010-04-30 13:33:04.567 java[17825:41b] *** _NSAutoreleaseNoPool(): Object 0x121000 of class NSCFString autoreleased with no pool in place - just leaking Stack: (0x944acf4f 0x943b9432 0x678fb79 0x35a19b1) 2010-04-30 13:33:04.581 java[17825:41b] *** _NSAutoreleaseNoPool(): Object 0x123720 of class NSPathStore2 autoreleased with no pool in place - just leaking Stack: (0x944acf4f 0x943ba637 0x943c238f 0x943c1e8e 0x943c694b 0x678992e 0x35a19b1) 2010-04-30 13:33:04.582 java[17825:41b] *** _NSAutoreleaseNoPool(): Object 0x12d660 of class NSPathStore2 autoreleased with no pool in place - just leaking Stack: (0x944acf4f 0x943ba637 0x943b9739 0x943c3eb2 0x943c6b22 0x678992e 0x35a19b1) ... ... ... The actual error is much larger, and continues until the program crashes. I know that I am using the correct swt.jar file and I have tried running the program with the -XstartOnFirstThread VM argument, but still have not had any luck. Does anybody have any ideas or any suggestions where I could start looking for a solution? Thanks.

• jQuery Mobile and Select menu with URLs

  - by user1907347

  Been battling with this for a while now. I'm trying to get a select menu to work as a navigation menu but I cannot get the URLs to work and have it actually change pages. In the head: <script> $(function() { $("#select-choice-1").click(function() { $.mobile.changePage($("#select-choice-1")); }); }); </script> With this Menu: <div id="MobileWrapper" data-role="fieldcontain"> <select name="select-choice-1" id="select-choice-1" data-theme="a" data-form="ui-btn-up-a" data-mini="true"> <option data-placeholder="true">Navigation</option><!-- data=placeholder makes this not show up in the pop up--> <option value="/index.php" data-ajax="false">Home</option> <option value="/services/index.php" data-ajax="false">Services</option> <option value="/trainers/index.php" data-ajax="false">Trainers</option> <option value="/locations/index.php" data-ajax="false">Locations</option> <option value="/calendar/index.php" data-ajax="false">Calendar</option> <option value="/contactus/index.php" data-ajax="false">Contact Us</option> </select> </div><!--END MobileWrapper DIV-->

• Keeping a web app project organized?

  - by user246114

  Hi, I'm writing a web app, using jsp to create the page content. I need a pretty good amount of javascript to make the app work. Does anyone have any recommendations on how to structure my project, such that it doesn't become a mess? This is a broad question, but the basic problem is that I'm insert javascript code directly into my jsp content. Then I might have some external js files. Ids and such are strewn between multiple files. I'm not really sure what a best practice is for keeping this type of project organized. Do you always keep your javascript in separate files? There has to be a few hooks in the jsp pages though for them, right? I tried using GWT because I'm really a c/java developer, and I was hoping it would help keep my project more organized (definitely helps) - but GWT is a pain to use with jsp, it really wants you to do all UI generation client side after the page is done loading, doesn't work for what I need to do. Again, broad question, any tips would be great, Thanks
