  • getHeaderField("WWW-Authenticate") giving improper value in J2ME

    - by kehers
    I'm building a client for an api that uses http digest access authentication for authentication. I have studied the rfc to know the setup the required response headers and this works well on my emulator. Problem however is when I test on my phone (nokia E5), I found out that getting the www-authenticate header from the returned headers doesnt get the full value [code] // c = (HttpConnection) Connector.open(url) and other declarations String digest = c.getHeaderField("WWW-Authenticate"); System.out.println(digest); // gives only: Digest //no realm, qop and others [/code] I'm I doing something wrong or it is from the phone? What are my other options?

  • URL getRequestParameterMap not working

    - by DD
    I'm using IceFaces 1.8.2 and trying to get a parameter from the URL using: ((HttpServletRequest) FacesContext.getCurrentInstance() .getExternalContext().getRequest()).getParameter(name); This works fine on the inital request. However, when I do a partialSubmit on a component, it stops working. I'm assuming that its to do with how requests are processed when partial submits are done. Is there a workaround? At the moment, I'm having to ((HttpServletRequest) FacesContext.getCurrentInstance().getExternalContext() .getRequest()).getQueryString(); and manually pass the query string. Thanks.

  • 1:M relationship in Hibernate and cascading operations

    - by EugeneP
    Table SUBCOURSE references COURSE COURSE(id, name) SUBCOURSE(id, course_id, name) So, 1:M. Hibernate generates for Course: @OneToMany(fetch = FetchType.LAZY, mappedBy = "course", cascade = CascadeType.ALL) public Set getSubCourses() { return this.subCourses; } for Subcourse it generates @ManyToOne(fetch = FetchType.LAZY) @JoinColumn(name = "course_id", nullable = false) public Course getCourse() { return this.course; } Now the problem is that cascading does not work as expected. I want to create a collection of SubCourse objects (Set), fill it and then bind it to setSubCourses() of Course object. Though, having ManyToOne thing in a Subcourses table, I need to manually setCourse() before adding to collection on each object. If I do not do so, an exception is raised. What can you recommend me?

  • Similar Sub-Classes

    - by praks5432
    Lets say I have a class A that is fairly simple like this - public class A{ private int randomField = 0; protected int key; protected double dmg; } Now I want to write a number of sub-classes that inherit the protected fields and only differ based on the initial values that are assigned to those fields - for example, if I wrote two subclasses B and C, the only difference between those two sub-classes would be that the values key and dmg would have different values. They would share a method, set, which would be exactly the same, in that it would affect the same variable. I find when I'm writing these sub-classes I'm repeating myself, as I just change the constructor to set different initial values to key and dmg, and simply copy and paste the set method. Is there a 'good' way to do this?

  • add objects with different name through for loop

    - by Gandalf StormCrow
    What is the best way to do the following: List<MyObject> list = new LinkedList<MyObject>(); for(int i=0; i<30;i++) { MyObject o1 = new MyObject(); list.add(o1); } But the things is I don't wanna create objects with same name, I wanna create them with different name like o1,o2,o3,o4,o5,o6,o7,o8,o9,o10 and I wanna add each to the list. What is the best way to do this ?

  • How the clients (client sockets) are identified?

    - by Roman
    To my understanding by serverSocket = new ServerSocket(portNumber) we create an object which potentially can "listen" to the indicated port. By clientSocket = serverSocket.accept() we force the server socket to "listen" to its port and to "accept" a connection from any client which tries to connect to the server through the port associated with the server. When I say "client tries to connect to the server" I mean that client program executes "nameSocket = new Socket(serverIP,serverPort)". If client is trying to connect to the server, the server "accepts" this client (i.e. creates a "client socket" associated with this client). If a new client tries to connect to the server, the server creates another client socket (associated with the new client). But how the server knows if it is a "new" client or an "old" one which has already its socket? Or, in other words, how the clients are identified? By their IP? By their IP and port? By some "signatures"? What happens if an "old" client tries to use Socket(serverIP,serverIP) again? Will server create the second socket associated with this client?

  • Are there any data-binding solution that works in C++ and GWT and supports structures polymorphism?

    - by user116854
    I expect it should share a common description, like XmlSchema or IDL and should generate classes for target language. I found Thrift and it's really nice solution, but it doesn't support structures polymorphism. I would like to have collections of base class objects, where I could place instances of subclasses, serialize this and deserialize at the opposite side. Some mechanism of polymorphic behavior support, like Visitor, would be a perfect. Does anybody know something suitable for these requirements?

  • Whats wrong with this while loop?

    boolean r = false ; int s = 0 ; while (r == false) ; { s = getInt() ; if (!(s>=0 && s<=2)) System.out.println ("try again not a valid response") ; else r = true ; } The text never displays itself even when a 3 or a 123 is entered and the loop never terminates. Whats wrong here?

  • Multiply without multiplication, division and bitwise operators, and no loops. Recursion

    - by lxx22
    public class MultiplyViaRecursion{ public static void main(String[] args){ System.out.println("8 * 9 == " + multiply(8, 9)); System.out.println("6 * 0 == " + multiply(6, 0)); System.out.println("0 * 6 == " + multiply(0, 6)); System.out.println("7 * -6 == " + multiply(7, -6)); } public static int multiply(int x, int y){ int result = 0; if(y > 0) return result = (x + multiply(x, (y-1))); if(y == 0) return result; if(y < 0) return result = -multiply(x, -y); return result; } } My question is very simple and basic, why after each "if" the "return" still cannot pass the compilation, error shows missing return.
