  • @Intertceptors does not work for web bean for JSF page.

    - by Drevlyanin
    @Named @ConversationScoped @Interceptors(MyInterceptor.class) public class BeanWeb implements Serializable { public String methodThrowException throws Exception() { throws new Exception(); } } public class MyInterceptor { @AroundInvoke public Object intercept(InvocationContext ic) throws Exception { try { return ic.proceed(); } catch (Exception e) { return null; } } } For @Stateless beans interceptor works, but for the BeanWeb interceptor does not work. And we have never entered into "intercept" method. Why is this happening? How could intercept method calls in BeanWeb? P.S.: All this spin under Glassfish 3.x.

  • Attribute vector emptying itself

    - by ravloony
    Hello, I have two classes, derived from a common class. The common class has a pure virtual function called execute(), which is implemented in both derived classes. In the inherited class I have an attribute which is a vector. In both execute() methods I overwrite this vector with a result. I access both classes from a vector of pointers to their objects. The problem is when I try to access the result vector form outside the objects. In one case I can get the elements (which are simply pointers), in the other I cannot, the vector is empty. Code: class E; class A{ protected: vector<E*> _result; public: virtual void execute()=0; vector<E*> get_result(); }; vector<E*> A::get_result() { return _result; } class B : public A { public: virtual void execute(); }; B::execute() { //... _result = tempVec; return; } class C : public A { public: virtual void execute(); }; C::execute() { //different stuff to B _result = tempvec; return; } main() { B* b = new B(); C* c = new C(); b->execute(); c->execute(); b->get_result();//returns full vector c->get_result(); //returns empty vector!! } I have no idea what is going on here... I have tried filling _result by hand from a temp vector in the offending class, doing the same with vector::assign(), nothing works. And the other object works perfectly. I must be missing something.... Any help would be greatly appreciated.

  • Converting keys of an array/object-tree to lowercase

    - by tstenner
    Im currently optimizing a PHP application and found one function being called around 10-20k times, so I'd thought I'd start optimization there. function keysToLower($obj) { if(!is_object($obj) && !is_array($obj)) return $obj; foreach($obj as $key=>$element) { $element=keysToLower($element); if(is_object($obj)) { $obj->{strtolower($key)}=$element; if(!ctype_lower($key)) unset($obj->{$key}); } else if(is_array($obj) && ctype_upper($key)) { $obj[strtolower($key)]=$element; unset($obj[$key]); } } return $obj; } Most of the time is spent in recursive calls (which are quite slow in PHP), but I don't see any way to convert it to a loop. What would you do?

    - by BobAlmond
    Hi all, I want to ask about pointer in C++ I have some simple code: int add(int a, int b){ return a+b; } int runner(int x,int y, int (*functocall)(int, int)){ return (*functocall)(x,y); } now, suppose I call those functions using this way : cout<<runner(2,5,&add); or maybe cout<<runner(2,5,add); is there any difference? because when I tried, the result is the same and with no error.

  • Performance implications of using a variable versus a magic number

    - by Nathan
    I'm often confused by this. I've always been taught to name numbers I use often using variables or constants, but if it reduces the efficiency of the program, should I still do it? Heres an example: private int CenterText(Font font, PrintPageEventArgs e, string text) { int recieptCenter = 125; int stringLength = Convert.ToInt32(e.Graphics.MeasureString(text, font)); return recieptCenter - stringLength / 2; } The above code is using named variables, but runs slower then this code: private int CenterText(Font font, PrintPageEventArgs e, string text) { return 125 - Convert.ToInt32(e.Graphics.MeasureString(text, font) / 2); } In this example, the difference in execution time is minimal, but what about in larger blocks of code?

  • Passing report values to a query

    - by Beavis
    I'm a novice with Microsoft Access as my background is mostly .NET. I'm sure what I'm trying to accomplish is dead simple but I need some direction. I have a report and a query. The query returns a single numeric value based on a single numeric criteria. Select total from table where id = [topic] I have placed a text box on my report so I can feed the id to this query and in return get the total. It seems like DLookUp is what I want but no matter how I construct it, I get an "#Error" in the text box when I run the report. Currently my DLookUp looks like this (I just hard-coded now for simplicity): =DLookUp("[total]","myquery","[topic] = 3") How can I pass a value from a field on my report to a query so I can return the query's single numeric value? Thanks.

  • Jquery Match() IP Address?

    - by user1635970
    I'm using a jquery script to validate form fields. This works well, but I'd like to change the validation of one field to check for IP Addresses. The regex I want to use is : \b(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\b How do I amend the below to work with this ? (This is how the validation works for email address) jQuery("#Email").validate({ expression: "if (VAL.match(/^[^\\W][a-zA-Z0-9\\_\\-\\.]+([a-zA-Z0-9\\_\\-\\.]+)*\\@[a-zA-Z0-9_]+(\\.[a-zA-Z0-9_]+)*\\.[a-zA-Z]{2,4}$/)) return true; else return false;", message: "Should be a valid Email id" });

  • Mapping restful ajax requests to spring

  • Returning and instance of a Class given its .class (MyClass.class)

    - by jax
    I have an enum that will hold my algorithms. I cannot instantiate these classes because I need the application context which is only available once the application has started. I want to load the class at runtime when I choose by calling getAlgorithm(Context cnx). How do I easily instantiate a class at runtime given its .class (and my constructor takes arguments)? All my classes are subclasses of Algorithm. public enum AlgorithmTypes { ALL_FROM_9_AND_LAST_FROM_10_ID(AlgorithmFactory.AlgorithmAllFrom9AndLastFrom10Impl.class), ALL_FROM_9_AND_LAST_FROM_10_CURRENCY_ID(AlgorithmFactory.AlgorithmAllFrom9AndLastFrom10Impl.class), DIVIDE_BY_9_LESS_THAN_100(AlgorithmFactory.AlgorithmAllFrom9AndLastFrom10Impl.class), TABLES_BEYOND_5_BY_5(AlgorithmFactory.AlgorithmAllFrom9AndLastFrom10Impl.class); private Class<? extends Algorithm> algorithm; AlgorithmTypes(Class<? extends Algorithm> c) { algorithm = c; } public Algorithm getAlgorithm(Context cnx) { return //needs to return the current algoriths constructor which takes the Context Algorithm(Context cnx); } }

  • Groovy: Dynamically addings methods with a specific signature.

    - by Reverend Gonzo
    So, I need to dynamically create (or inject) methods into an object that have a specific return type and method signature, because a Java tool we're using will be finding this methods via Reflection and checks for void type. Method names will be determined at runtime. Using metaClass. = { ... } however adds a closure which doesn't show up as a regular method (even if it can be used as one) and also has a return type. I can't modify the method finding code, and it it not Groovy-aware. I can't use methodMissing() or invokeMethod() because the method needs to actually exist. If I could overload class.getMethods() I think it would be possible, but I can't figure out how. Is there any way to do this in Groovy?

  • [grails + xfire] How to handle errors in SOAP services?

    - by Mulone
    Hi all, I'm implementing a web service on the xfire plugin. I was wondering how I'm supposed to handle the errors. I tried with this setup but the error is not returned to the SOAP client: GaSession[] myMethod( String userId ) throws MyException{ GaUser user = GaUser.findByUserId( userId ) if (!user) throw new MyException("user ${userId} does not exist") // do stuff and return valid results } Is there a standard way to handle errors and return them to the client in a clear way? My log is full of messages like: 2010-06-13 18:20:40,926 [Thread-289] DEBUG aegis.XMLClassMetaInfoManager - Mapping file : /com/mycompany/MyClass.aegis.xml not found. Is there a way to fix this?

Here is the code: Node* search(Node* head, int x) { if(!head) return NULL; else if(x == head->key) return head; else if(x < head->key) search(head->lchild, x); else search(head->rchild, x); } I got the same warning when compiling it in Linux, but got the correct result. But in Xcode, the result was wrong. By the way, I got the correct answer and no warning in Visual Studio.

  • PHP - BUG with filter_var and FILTER_VALIDATE_FLOAT

    - by Samuele
    I think there is a bug in this filter_var or maybe I'm doing something wrong: Try this: $options = array( 'options' => array( 'default' => 3, 'min_range' => 1000.0, 'max_range' => 5000.6, ) ); $VariableValue2 = 5698; $VariableValue4 = 5698.2; $chicco3 = filter_var($VariableValue2, FILTER_VALIDATE_INT, $options); $chicco4 = filter_var($VariableValue4, FILTER_VALIDATE_FLOAT, $options); It suppose to don't validate it... Infact the value: 5698 is greater than 5000.6!!!! But with FILTER_VALIDATE_INT it work FINE!! It return 3 that is the default value in case it don't validate it... PERFECT... Instead, with FILTER_VALIDATE_FLOAT it validate it... It return 5698.2!!! I'm doing something wrong??? Thank you to everybody... Samuele
