• Best practices for an internal webservice

  - by sankara

  Experience says that using WSDL-SOAP based webservice for internal consumption is an overkill. There are too many service-based POJO classes that when let into the system complicates it way too much. One option would be use adapter pattern, map the request/response objects to internal domain classes and . But is it even required? Is there a better approach? What are your suggestions?

• Spring @Transactional Annotation Best Practice

  - by Thomas Einwaller

  We are currently discussing the Best Practice for placing the @Transactional annotations in our code. Do you place the @Transactional in the DAO classes and/or their methods or is it better to annotate the Service classed which are calling using the DAO objects? Or does it make sense to annotate both "layers"?

• accessing id property via javascript

  - by webzide

  Dear experts Is there a way to access the ID of an dom element? I don't mean using the getElementById attribute to find out a array of objects. Bascially I already know the DOM element and that object reference is at hand. All I need is to access the ID property. I know something like if(element.id==value) won't work. Thanks in advance.

• [C++] STL list - how to find a list element by its object fields

  - by Dominic Bou-Samra

  I have a list: list<Unit *> UnitCollection; containing Unit objects, which has an accessor like: bool Unit::isUnit(string uCode) { if(this->unitCode == uCode) return true; else return false; } How do I search my UnitCollection list by uCode and return the corresponding element (preferably it's index). I have looked at the find() method, but i'm not sure you can pass a boolean method in instead of a searched item parameter if that makes sense.

• Iterating through child components

  - by ken

  I have button-group component which contains a set of button-element components. The template is defined as: {{#each buttons}} {{button-element titleBinding="title" action="buttonAction"}} {{/each}} I'd like the buttonAction() method in the button-group component to have easy access to the set of button-element components and iterate through them. What's the easiest way to do this? I know I could use a jQuery/DOM approach like: this.$('.btn').doSomething(); But I'd like to address the component objects not the DOM directly.

• Correcting a plist with dictionaries

  - by ingenspor

  Plist is copyed to documents directory if it doesn't exist. If it already exists, I want to use the "Name" key from NSDictionary in bundleArray to find the matching NSDictionary in documentsArray. When the match is found, I want to check for changes in the strings and replace them if there is a change. If a match is not found it means this dictionary must be added to documents plist. This is my code: - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { [self managePlist]; return YES; } - (void)managePlist { NSError *error; NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSString *path = [documentsDirectory stringByAppendingPathComponent:@"Objects.plist"]; NSString *bundle = [[NSBundle mainBundle] pathForResource:@"Objects" ofType:@"plist"]; NSFileManager *fileManager = [NSFileManager defaultManager]; if (![fileManager fileExistsAtPath: path]) { [fileManager copyItemAtPath:bundle toPath:path error:&error]; } else { NSArray *bundleArray = [[NSArray alloc] initWithContentsOfFile:bundle]; NSMutableArray *documentArray = [[NSMutableArray alloc] initWithContentsOfFile:path]; BOOL updateDictionary = NO; for(int i=0;i<bundleArray.count;i++) { NSDictionary *bundleDict=[bundleArray objectAtIndex:i]; BOOL matchInDocuments = NO; for(int ii=0;ii<documentArray.count;ii++) { NSMutableDictionary *documentDict = [documentArray objectAtIndex:ii]; NSString *bundleObjectName = [bundleDict valueForKey:@"Name"]; NSString *documentsObjectName = [documentDict valueForKey:@"Name"]; NSRange range = [documentsObjectName rangeOfString:bundleObjectName options:NSCaseInsensitiveSearch]; if (range.location != NSNotFound) { matchInDocuments = YES; } if (matchInDocuments) { if ([bundleDict objectForKey:@"District"] != [documentDict objectForKey:@"District"]) { [documentDict setObject:[bundleDict objectForKey:@"District"] forKey:@"District"]; updateDictionary=YES; } } else { [documentArray addObject:bundleDict]; updateDictionary=YES; } } } if(updateDictionary){ [documentArray writeToFile:path atomically:YES]; } } } If I run my app now I get this message: '-[__NSCFDictionary setObject:forKey:]: mutating method sent to immutable object' How can I fix this? When this is fixed, do you think my code will work? If not, I would be happy for some suggestions on how to do this. I have struggled for a while and really need to publish the update with the corrections! Thanks a lot for your help.

• If you stick to standard coding in .NET, is there reason to manually invoke the GC or run finalizers

  - by Matt

  If you stick to managed code and standard coding (nothing that does unconventional things withe CLR) in .NET, is there any reason to manually invoke the GC or request to run finalizers on unreferenced objects? The reason I ask is thaty I have an app that grows huge in Working Memory set. I'm wondering if calling System.GC.Collect(); and System.GC.RunFinalizers(); would help, and if it would force anything that wouldn't be done by the CLR normally anyways.

• How could I generate instances of an object randomly at the top of the screen and make them "fall"?

  - by Custard

  I am making a game in Flash CS4 (actionscript 3) and I would like to be able to make "copies" of an instance that would randomly appear at the top of the screen and fall. For example, multiple objects(that are the same one) are falling from the top of the screen continuously, starting at random X positions. (i think this would be considered Real-Time effect). P.S., please tell me if the information is insufficient for an answer, I couldn't think of much more to add to it. Thanks for your time and answers, -Custard

• Setting custom SQL in django admin

  - by eugene y

  I'm trying to set up a proxy model in django admin. It will represent a subset of the original model. The code from models.py: class MyManager(models.Manager): def get_query_set(self): return super(MyManager, self).get_query_set().filter(some_column='value') class MyModel(OrigModel): objects = MyManager() class Meta: proxy = True Now instead of filter() I need to use a complex SELECT statement with JOINS. What's the proper way to inject it wholly to the custom manager?

• shared_ptr as class member

  - by idimba

  It's common to declared contained objects as a pointers to that class, while "forward declarating" them in header file. This in order to reduce physical dependencies in code. For example class B; // forward declaration class A { private: B* pB; }; Would it be good idea to declare such a member as shared_ptr, instead of naked pointer? I would prefer scoped_ptr, but AFAIKit it won't be in standard.
