  • Architecture of a secure application that encrypts data in the database.

    - by Przemyslaw Rózycki
    I need to design an application that protects some data in a database against root attack. It means, that even if the aggressor takes control over the machine where data is stored or machine with the application server, he can't read some business critical data from the database. This is a customer's requirement. I'm going to encrypt data with some assymetric algorithm and I need some good ideas, where to store private keys, so that data is secure as well as the application usability was quite comfortable? We can assume, for simplicity, that only one key pair is used.

  • JNI AttachCurrentThread NULLs the jenv

    - by Damg
    Hello all, I'm currently in the process of adding JNI functionality into a legacy delphi app. In a single-threaded environment everything works fine, but as soon as I move into multi-threaded environment, things start to become hairy. My problem is that calling JavaVM^.AttachCurrentThread( JavaVM, @JEnv, nil ); returns 0, but puts the JEnv pointer to nil. I have no idea why jvm.dll should return a NULL pointer. Is there anything I am missing? Thank you in advance -- damg PS: * Environment: WinXP + JDK 1.6 * Using JNI.pas from http://www.pacifier.com/~mmead/jni/delphi/

  • Querying my JPA provider (Hibernate) for a collection of <Id,Name> of an entity

    - by Ittai
    Hi, I have an entity which looks something like this: Id (PK) Name Other business properties and associations... I have the need for my DAL (JPA with hibernate as provider) to return a list of the entities which correlate to some constraints (or just return them all) but instead of returning the entities themselves I'd like to receive only the Id and the Name properties. I know this can be achieved with HQL/SQL (something like: select id,name from entity where...) but I don't want to go down that road. I was thinking of somehow defining the pair a compositioned part of the entity and thought that might help me but I'm not sure that's "legal" as the Id is the PK. The logic for this scenario is to have a textbox which asynchronously queries the web-service (and through it the DAL) for the relevant entities and once an entity is selected then it is loaded as a whole and shipped to the front-end. Would appreciate any feedback, Ittai

  • J2SE Client Server App: Client calls RMI method. Server handles RMI method and returns, but Client

    - by Mike
    J2SE Client Server App: Client calls RMI message. Server handles RMI method and returns, but Client never receives it. Any ideas how this could happen? Our attempted solution is to set client read timeouts and come up with a framework for resending requests or otherwise handling those failures gracefully. But really, I'd like to know any root causes for how this might happen rather than addressing the symptoms.

  • Sharing application classloaders on weblogic

    - by mR_fr0g
    My project has several deployed artifacts as ear files. My understanding is that each of the ears will have it's own classloader. Is it possible to tell weblogic to use the same classloader for each of these deployables. What factors do i need to consider when making this change?

  • Does GAE/OpenID/OAuth support xmlhttp proxy?

    - by h2g2java
    Currently, my code would construct the GWT form, which user would submit directly to openId (or any authenticaiton service). Such a method works fine. However, what if I had the gwt page server access the OpenID provider, is there a way/strategy for the server to mediate authentication between its client and the auth provider? I wish to know the answers with respect to GAE as the proxy and, regardless if GAE or Tomcat is the intended proxy, answers wrt Google Accounts OpenID OAuth If so, it would be wonderful if someone could describe the installation strategy.

  • how to go the middle of the singularly linked list in one iteration?

    - by u3050
    Recently I have been asked one question that in a singularly linked list how do we go to the middle of the list in one iteration. A --> B --> C --> D (even nodes) for this it should return address which points to B A --> B --> C (odd nodes) for this also it should return address which points to B There is one solution of taking two pointers one moves one time and other moves two times but it does not seem working here LinkedList p1,p2; while(p2.next != null) { p1 = p1.next; p2 = p2.next.next; } System.out.print("middle of the node" + p1.data); //This does not give accurate result in odd and even Please help if anyone has did this before.

  • TestNG - Factories and Dataproviders

    - by Tim K
    Background Story I'm working at a software firm developing a test automation framework to replace our old spaghetti tangled system. Since our system requires a login for almost everything we do, I decided it would be best to use @BeforeMethod, @DataProvider, and @Factory to setup my tests. However, I've run into some issues. Sample Test Case Lets say the software system is a baseball team roster. We want to test to make sure a user can search for a team member by name. (Note: I'm aware that BeforeMethods don't run in any given order -- assume that's been taken care of for now.) @BeforeMethod public void setupSelenium() { // login with username & password // acknowledge announcements // navigate to search page } @Test(dataProvider="players") public void testSearch(String playerName, String searchTerm) { // search for "searchTerm" // browse through results // pass if we find playerName // fail (Didn't find the player) } This test case assumes the following: The user has already logged on (in a BeforeMethod, most likely) The user has already navigated to the search page (trivial, before method) The parameters to the test are associated with the aforementioned login The Problems So lets try and figure out how to handle the parameters for the test case. Idea #1 This method allows us to associate dataproviders with usernames, and lets us use multiple users for any specific test case! @Test(dataProvider="players") public void testSearch(String user, String pass, String name, String search) { // login with user/pass // acknowledge announcements // navigate to search page // ... } ...but there's lots of repetition, as we have to make EVERY function accept two extra parameters. Not to mention, we're also testing the acknowledge announcements feature, which we don't actually want to test. Idea #2 So lets use the factory to initialize things properly! class BaseTestCase { public BaseTestCase(String user, String password, Object[][] data); } class SomeTest { @Factory public void ... } With this, we end up having to write one factory per test case... Although, it does let us have multiple users per test-case. Conclusion I'm about fresh out of ideas. There was another idea I had where I was loading data from an XML file, and then calling the methods from a program... but its getting silly. Any ideas?

  • Is it OK to write a constructor which does nothing?

    - by Roman
    To use methods of a class I need to instantiate a class. At the moment the class has not constructor (so I want to write it). But than I have realized that the constructor should do nothing (I do need to specify values of fields). In this context I have a question if it is OK to write constructor which does nothing. For example: public Point() { }

  • Maven profile for single module

    - by c0mrade
    I have a multi module maven project, which builds successfully, I'd like to build just one of the modules I have. How would I do that with profiles ? I could do it from console in two ways, one way is go to the child module and mvn package or I could use reactor to build just one module. Can I do the same thing with profiles? By modifying POM? Thank you EDIT If is impossible from POM, can I do it from settings.xml ?

  • How do I pass an ArrayList to method that takes a collection as an input

    - by Ankur
    I want to pass some ArrayList X into method a(Collection someCol) that takes Collection as an input. How can I do this? I thought an ArrayList was a Collection and thus I should be able to "just do it" but it seems that Collection is an interface and ArrayList implements this interface. Is there something I can do to make this work ... if you understand the theory that would also help me and possibly lots of other people. Thanks

  • Is there a better way than a sequence of if's to handle events?

    - by Matt
    I recently ran across several objects implemented to handle events with a hard coded mapping using this pattern: public void handleEvent(Event event) { if(event.getCode() == SOME_STATIC_EVENT) doSomething(event); if(event.getCode() == ANOTHER_STATIC_EVENT) doSomethingElse(event); } where doSomething functions are implemented as methods of the same class. In hopes of striving for looser coupling, how would you suggest abstracting out this pattern? Also, what's the best approach for mapping 0..N functions to a fired event?

  • Drools rule to filter element with a numeric property below a percentage of the total

    - by Mario
    Hello, I have just started using Drools on a small project and now I need to write a rule a bit complex and I don't really know what's the best way to do it. I am applying this rule to a list of objects of the same type (this class have a property called numberOfExecutions). I need to check for each element of the list if the numberOfExecutions of that element is bigger than 5% of the total numberOfExecutions (the sum of numberOfExecutions of all the elements in the list). I could not think of a nice way to implement this in drools so far, do you have a suggestion?

  • XML Doc to JSP to TIFF

    - by SPD
    We have around 100 word templates, every time user gets a business request he goes into shared folder select the template he/she wants and enter information and save it as tiff, these tiffs later processed by some batch program. I am trying to automate this process. So I defined an XML which has Template information like <Template id="1"> <Section id="1"> <fieldName id="1">Date</fieldName> <fieldValue></fieldValue> <fieldtype></fieldType> <fieldProperty>textField</fieldProperty> </Section> <Section id="2"> <fieldName id="2">Claim#</fieldName> <fieldValue></fieldValue> <fieldtype></fieldType> <fieldProperty>textField</fieldProperty> </Section> </Template> Based on the template values I generate the JSP on fly. Now I would like to generate a TIFF file out of it in specified format. I am not sure how to handle this requirement. *edited the original question.

  • Is there a design pattern to cut down on code duplication when subclassing Activities in Android?

    - by Daniel Lew
    I've got a common task that I do with some Activities - downloading data then displaying it. I've got the downloading part down pat; it is, of course, a little tricky due to the possibility of the user changing the orientation or cancelling the Activity before the download is complete, but the code is there. There is enough code handling these cases such that I don't want to have to copy/paste it to each Activity I have, so I thought to create an abstract subclass Activity itself such that it handles a single background download which then launches a method which fills the page with data. This all works. The issue is that, due to single inheritance, I am forced to recreate the exact same class for any other type of Activity - for example, I use Activity, ListActivity and MapActivity. To use the same technique for all three requires three duplicate classes, except each extends a different Activity. Is there a design pattern that can cut down on the code duplication? As it stands, I have saved much duplication already, but it pains me to see the exact same code in three classes just so that they each subclass a different type of Activity.

  • Write to text file using ArrayList

    - by Ugochukwutubelum Chiemenam
    The program is basically about reading from a text file, storing the current data into an ArrayList, then writing data (from user input) into the same text file. Kindly let me know where I am going wrong in this sub-part? The data inside the text file is as follows: abc t1 1900 xyz t2 1700 The compiler is showing an error at the line output.format("%s%s%s%n", public class justTesting { private Scanner input; private Formatter output; private ArrayList<Student> tk = new ArrayList<Student>(); public static void main(String[] args) { justTesting app = new justTesting(); app.create(); app.writeToFile(); } public void create() { Text entry = new Text(); Scanner input = new Scanner(System.in); System.out.printf("%s\n", "Please enter your name, ID, and year: "); while (input.hasNext()) { try { entry.setName(input.next()); entry.setTelNumber(input.next()); entry.setDOB(input.next()); for (int i = 0; i < tk.size(); i++) { output.format("%s%s%s%n", tk.get(i).getName(), tk.get(i) .getTelNumber(), tk.get(i).getDOB()); } } catch (FormatterClosedException fce) { System.err.println("Error writing to file."); return; } catch (NoSuchElementException nsee) { System.err.println("Invalid input. Try again: "); input.nextLine(); } System.out.printf("%s\n", "Please enter your name, ID, and year: "); } } public void writeToFile() { try { output = new Formatter("testing.txt"); } catch (SecurityException se) { System.err .println("You do not have write access permission to this file."); System.exit(1); } catch (FileNotFoundException fnfe) { System.err.println("Error opening or creating file."); System.exit(1); } } }
