• Seam app with JBoss 'minimal' Config?

  - by Shadowman

  I'd like to improve the performance of my Seam apps and JBoss appserver, particularly by removing things that aren't necessary in the standard configuration. Ideally, I'd like to be able to run it using the "minimal" profile. Can anyone give me any guidance as to what is needed to run a Seam app using "minimal"? Here are the kind of things my app requires: JPA, using Hibernate with a PostgreSQL backend EJB3 JSF (RichFaces/Facelets) E-mail, eventually, although not required at this particular moment I'll be developing my app using JBoss Tools on Eclipse, so I would also need anything that is required by the tools for development and deployment. I've found that the default configuration just has too many additional components and features installed by default, and that greatly affects performance when I'm trying to develop. Any help you can give would be great! Thanks!

• wanting a good memory + disk caching solution

  - by brofield

  I'm currently storing generated HTML pages in a memcached in-memory cache. This works great, however I am wanting to increase the storage capacity of the cache beyond available memory. What I would really like is: memcached semantics (i.e. not reliable, just a cache) memcached api preferred (but not required) large in-memory first level cache (MRU) huge on-disk second level cache (main) evicted from on-disk cache at maximum storage using LRU or LFU proven implementation In searching for a solution I've found the following solutions but they all miss my marks in some way. Does anyone know of either: other options that I haven't considered a way to make memcachedb do evictions Already considered are: memcachedb best fit but doesn't do evictions: explicitly "not a cache" can't see any way to do evictions (either manual or automatic) tugela cache abandoned, no support don't want to recommend it to customers nmdb doesn't use memcache api new and unproven don't want to recommend it to customers

• GUI design techniques to enhance user experience

  - by aku

  What techniques do you know\use to create user-friendly GUI ? I can name following techniques that I find especially useful: Non-blocking notifications (floating dialogs like in Firefox3 or Vista's pop-up messages in tray area) Absence of "Save" button MS OneNote as an example. IM clients can save conversation history automatically Integrated search Search not only through help files but rather make UI elements searchable. Vista made a good step toward such GUI. Scout addin Microsoft Office was a really great idea. Context oriented UI (Ribbon bar in MS Office 2007) Do you implement something like listed techniques in your software? Edit: As Ryan P mentioned, one of the best way to create usable app is to put yourself in user's place. I totally agree with it, but what I want to see in this topic is specific techniques (like those I mentioned above) rather than general recommendations.

• Android Developers, Are you adding APP 2 SD in a future app release and if so for which applications

  - by Anthony

  For Android application developers regarding 2.2 and the new App 2 SD feature. Android 2.2 now allows you to have your applications installed onto the SD card instead of using the phones internal memory. Will any of you be adding this feature onto your next release and if so what is your app? I know applications built with the App 2 SD function cannot be used when the SD card is mounted. Maybe 2 versions of each app on the market would work out great for those that would need an app while the phone is mounted. What do you think about this idea? Are you aware of any other negative issues that arise from an application built for this feature?

• Can FLV AAC stream be played in Android

  - by HariKJ

  Hi, I'm trying to build a radio player and the client is providing a stream which is a FLV container with the audio being AAC When I read the headers it shows up as audio/aacp. I have tried all possible ways such as using the 1) Streaming through mediaplayer (Does not work) 2) Use the NPR mode of using a proxy stream (I get a broken pipe exception) 3) Play it in chunks ( Plays but I need the SDCard and the playback is not very great) 4) Use the GPL'd FAAD2 Library but I would have to pay the royalty fee Can some one help me out on figuring this issue out. The last option that I have is to have my client change the stream to mp3 container (which I know that it works) Regards, Hari

• generate Grid from template

  - by theXs

  Howdy, I've got another question regarding phone 7... I want to generate a couple of Grids in a stackpanel - since they all have the same layout I thought it would be a great idea to use DataTemplates ... But then I found that the GRID Object has no "DataTemplate" Property and now I'm kinda stuck ... the template which I use is the following: <DataTemplate x:Key="Speise"> <Grid> <TextBlock Height="36" Margin="8,43,104,0" TextWrapping="Wrap" Text="TextBlock" VerticalAlignment="Top"/> <TextBlock HorizontalAlignment="Right" Height="36" Margin="0,44,8,0" TextWrapping="Wrap" Text="TextBlock" VerticalAlignment="Top" Width="92"/> </Grid> </DataTemplate> The way I now thought of creating my objects is: Grid blubber = (Grid)this.Resources["Speise"]; But that is not working ... I think it's again a really short thing, but I have no clue of how to google for it :(

• How to exclude results with get_object_or_404?

  - by googletorp

  In Django you can use the exclude to create SQL similar to not equal. An example could be. Model.objects.exclude(status='deleted') Now this works great and exclude is very flexible. Since I'm a bit lazy, I would like to get that functionality when using get_object_or_404, but I haven't found a way to do this, since you cannot use exclude on get_object_or_404. What I want is to do something like this: model = get_object_or_404(pk=id, status__exclude='deleted') But unfortunately this doesn't work as there isn't an exclude query filter or similar. The best I've come up with so far is doing something like this: object = get_object_or_404(pk=id) if object.status == 'deleted': return HttpResponseNotfound('text') Doing something like that, really defeats the point of using get_object_or_404, since it no longer is a handy one-liner. Alternatively I could do: object = get_object_or_404(pk=id, status__in=['list', 'of', 'items']) But that wouldn't be very maintainable, as I would need to keep the list up to date. I'm wondering if I'm missing some trick or feature in django to use get_object_or_404 to get the desired result?

• Gson serialization depending on field value

  - by Serj Lotutovici

  I have a POJO that is similar to: public class MyGsonPojo { @Expose @SerializedName("value1") private String valueOne; @Expose @SerializedName("value2") private boolean valueTwo; @Expose @SerializedName("value3") private int valueThree; // Getters and other stuff here } The issue is that this object has to be serialized into a json body for a call to the server. Some fields are optional for the request and if I even send it with default and null values, the API responds differently (Unfortunately changing the api is not an option). So basically I need to exclude fields from serialization if any of them is set to a default value. For example if the field valueOne is null the resulting json should be: { "value2" : true, "value3" : 2 } Any idea how to make this a painless effort? I wouldn't want to build the json body manually. Any help would be great. Thank you in advice.

• How do I set up a test duplicate of a Django and Postgresql based web application?

  - by cojadate

  Not sure if this is an excessively broad and newbie-ish question for Stack Overflow but here goes: I paid someone else to build a web application for me and now I want to tweak certain aspects of it myself. I learn best by trial and error – changing stuff and seeing what happens. Obviously that's not a great way to treat a live site, so I need to duplicate the site on some kind of test server which I can play with without fear of the consequences. Unfortunately the closest I've come to programming has been creating ActionScript-based websites. I've never touched a database. So I really don't know where to start with setting up a test server. I would really appreciate any advice about where to start. I am completely ignorant and lost here. The web application is built in python/django using a Postgresql database. I use Mac OS X 10.6 if that makes any difference.

• last_login_at not working (null) w/ Authlogic Magic Columns...

  - by bgadoci

  I am using the Authlogicgem for authentication and most of it seems to be working great. Authlogic provides several columns that you can add to your Users table (for example) that it knows to fill in if they are present. i.e. login_count, current_login_ip, last_request_at and last_login_at. All seem to be working fine with the exception of the last_login_at field which is null for each user. Is there anything specific that could be causing this perhaps having to do with the user sessions, etc? I can post code if needed but wasn't sure what would relate to this.

• workflow assign task to multiple users

  - by Artru

  I have MOSS. I want to make a page where a user, say administrator, could send some instructions to a server, for example using standard library and make task for a group of users forcing them to read files. After the reading users would press "already read it" and administrator would know who did it/who did not. I created simple workflow in office designer and choose assigne task to Group1, which is in the sharepoint server. After WF run everyone who is in Group1 get message about a task, that's great. However this task is general for group and if we go to the site section "current tasks", we can see it, while I want this task for every person in Group1. Futher question, is it possible to create form where administrator will choose users for this task, 'cause now I munualy set group in WF.

• Livevalidation: only validate when default value is changed

  - by usr122212

  Hello there! I am validating my html form with livevalidation and everything works great except for one feature. I have a input field with a default value age, I only want the livevalidation to validate when it says something other than "age". so maybe the user will type in 20 then the validation will fire checking its things but if left as "age" it won't check it all. But as of now, it just checks everything with a validation script and this is a problem for me as I have lots of fields in my form and some of them are optional so when I hit submit, the livevalidation checks the age field as well even if the user didnt touch it to begin with. Would this be possible with livevalidation ? Thanks for the help.

• Creating controls in ASP with dynamic IDs

  - by mattdell

  Hi, I'm creating a chat widget that will be dropped into CommunityServer. The widget works great, but I just discovered that if I drop two of these widgets onto the same page, only one of them works! And I'm quite certain the reason is because the chat window is defined in ASP, and now there are two instances of the chat window, with the same ID, on the same page. I am doing this with straight ASP & Javascript (not by choice), so my chat window is defined as: <telerik:RadListBox ID="rlbMessages" runat="server" > (don't mind that it's a telerik control). So I was hoping I could do something like this: <telerik:RadListBox ID="<%= 'rlbMessages' + chatRoomID %>" runat="server" > But from what I've gathered, apparently you can't assign ID's this way? What is the alternative?

• Learning to use open source software [closed]

  - by dole

  Do you know any book, blog, tutorial which explains in a detailed way the use of some open source projects? Maybe you have written such a tutorial, example of open source libraries, and your final product is great for a beginner to understand it. I'm in the learning stage of OOP and I really need to learn by examples. I'll like to find some text which explains the use of some open source software/libraries and the good practices. Beign honestly I feel scared to use the open source libraries as I wish/think at this moment. I feel like as I still write procedural code and not OOP. Do you know such tutorials, links, blogs, stories, pages? PS: I know C and PHP. I can't say that I know C++ yet, and that's why I need your help.

• Using NSThread to solve waiting for image from URL on the iPhone

  - by james.ingham

  So I have the following code in a method which I want to set a UIImageView image to that of one from an online source: [NSThread detachNewThreadSelector:@selector(loadImage) toTarget:self withObject:nil]; Then in the method called by the thread I have this: - (void) loadImage { NSURL *url = [NSURL URLWithString:logoPath]; // logoPath is an NSString with path details NSData *data = [NSData dataWithContentsOfURL:url]; logoImage.image = [UIImage imageWithData:data]; } This works great however I get many warnings within the Debugger Console along the lines of: 2010-05-10 14:30:14.052 ProjectTitle[2930:633f] * _NSAutoreleaseNoPool(): Object 0x169d30 of class NSHTTPURLResponse autoreleased with no pool in place - just leaking This occurs many times each time I call the new thread and then eventually, under no pattern, after calling a few of these threads I get the classic 'EXC_BAD_ACCESS' run-time error. I understand that this is happening because I'm not retaining the object but how can I solve this with the code in 'loadImage' shown above? Thanks

• How to animate a UIButton selected background Image

  - by Thomas Joos

  hi all, I have a class defining a custom UIButton. I configurate a normal and selected state like this: //custom image UIImage *image = [UIImage imageNamed:@"customIconCreationBG.png"]; UIImage *stretchImage = [image stretchableImageWithLeftCapWidth:0.0 topCapHeight:0.0]; [self setBackgroundImage:stretchImage forState:UIControlStateNormal]; UIImage *imageSelected = [UIImage imageNamed:@"customIconCreationBG_selected.png"]; UIImage *stretchImageSelected = [imageSelected stretchableImageWithLeftCapWidth:0.0 topCapHeight:0.0]; [self setBackgroundImage:stretchImageSelected forState:UIControlStateSelected]; In another class I'm filling an array with custom buttons and i'm adding a button pressed method. It sets the selected state to TRUE -(void)buttnPressed:(id)sender { NSLog(@"button pressed"); [[NSNotificationCenter defaultCenter] postNotificationName:@"unselectBGIcons" object:self]; HorizontalListIcon *pressedIcon = ((HorizontalListIcon *)sender); [pressedIcon setSelected:TRUE]; } The button switches to another background, which is great. Is there a way to animate this change ( fading in? ) because it's a bit hard now. Greets

• TextMate/Macfusion combo for mounting projects over SSH

  - by Sam Lee

  Here is my workflow: I use Macfusion to mount a server over SSH, and then edit the root directory of the project in TextMate (using mate /Volumes/server/projectdir). I have a plug in installed that disables refreshing on refresh. This works ALMOST perfectly--the only thing I have problems with is "Find in Project": it's REALLY slow. Has anyone run into this problem before and been able to find any solutions? Currently I go to terminal when I have to do a search, but it would be great to be able to do it in TextMate. Thanks!

  - by Diver D

  HI there I am hoping for some help with a query I have. I have this query var group = from r in CustomerItem group r by r.StoreItemID into g select new { StoreItemID = g.Key, ItemCount = g.Count(), ItemAmount = Customer.Sum(cr => cr.ItemAmount),RedeemedAmount = Customer.Sum(x => x.RedeemedAmount) }; I am returning my results to a list so I can bind it listbox. I have a property called EntryType which is an int. There are 2 available numbers 1 or 2 Lets say I had 3 items that my query is working with 2 of them had the EntryType = 1 and the 3rd had EntryType2. The first records had a ItemAmount of 55.00 and the 3rd had a ItemAmount of 50.00 How can I group using something simlar to above but minus the ItemAmount of 50.00 from the grouped amount to return 60.00? Any help would be great!!

• Selenium not finding LiveValidation text.

  - by McNabbToSkins

  I am using the Selenium IDE to test some of my web development. I am using the JQuery LiveValidation in my code. I have an input box with some javascript behind it that will do a regular expresson and either ouput "OK" or "Error" next to the input text box based on what the user has entered. For some reason when testing with selenium the LiveValidation will not get triggered no matter what I do and therefore I can not test it. When I do it manually it works great. Has anyone run into this problem before? Any help would be appreciated.

• Creating C# form fields with events based off of a text file

  - by evolve

  I need to generate windows form fields based off of a text file that I am parsing. I also want to automatically generate validation event handlers which all will be basically the same only the form field and the regular expression which is used to validate the field will change. I'm having a difficult time figuring out the quickest and easiest method to go about doing this. Any pointers in the right direction would really be great, maybe even some keywords that I'm missing. I can only imagine this type of question has been covered before, I just don't know what I'm searching for really.

• Object reference not set to an instance of an object - how to find the offending object name in the

  - by Jason

  This is the bane of my programming existence. After deploying an application, when this error crops up, no amount of debug dump tells you WHAT object was not instantiated. I have the call stack, that's great, it tells me roughly where the object is, but is there any way to get .NET to tell me the actual name of the object? If you catch them while debugging, of course the program breaks right on the offending creature, but if it happens after the program is in the wild, good luck. There has to be a way. I've explored the exceptions returned in these instances and there is just nothing helpful.

• Preventing cross-site scripting in ASP.NET MVC - using jQuery or standard HtmlHelpers

  - by user313353

  I am building an ASP.NET MVC application that is AJAX-driven. For some reason I need to add some DOM elements on the fly when clicking a submit button. This is accomplished with jQuery.append(). One element inserted is a textarea, whose the data must be parse before submitting to ensure that no cross-site scripting can be done. We know that the Html.Encode() works great but must be declared outside a script tag. All I have done with jQuery is embedded within a script tag. 1) Is there a way to take advantage of the Html.Encode() within a script tag? 2) How can I accomplish this with jQuery? At worst I can use HttpUtility.HtmlEncode(), which is called on the server-side. Thanks for your help. Roland
