  • User Session Management with Spring

    - by Chris
    I am developing a flex java - spring web app and have set up the business logic using hibernate. I want to maintain sessions so that when the user logs in , i can track the logged in user to display information that is related to the username. I want to do this using spring if possible and wondered if anyone could redirect me to a tutorial or even explain the method to which this is achieved , or if it is hard to achieve. Thanks Chris

  • How to get started with testing(jMock)

    - by London
    Hello, I'm trying to learn how to write tests. I'm also learning Java, I was told I should learn/use/practice jMock, I've found some articles online that help to certain extend like : http://www.theserverside.com/news/1365050/Using-JMock-in-Test-Driven-Development http://jeantessier.com/SoftwareEngineering/Mocking.html#jMock And most articles I found was about test driven development, write tests first then write code to make the test pass. I'm not looking for that at the moment, I'm trying to write tests for already existing code with jMock. The official documentation is vague to say the least and just too hard for me. Does anybody have better way to learn this. Good books/links/tutorials would help me a lot. thank you EDIT - more concrete question : http://jeantessier.com/SoftwareEngineering/Mocking.html#jMock - from this article Tried this to mock this simple class : import java.util.Map; public class Cache { private Map<Integer, String> underlyingStorage; public Cache(Map<Integer, String> underlyingStorage) { this.underlyingStorage = underlyingStorage; } public String get(int key) { return underlyingStorage.get(key); } public void add(int key, String value) { underlyingStorage.put(key, value); } public void remove(int key) { underlyingStorage.remove(key); } public int size() { return underlyingStorage.size(); } public void clear() { underlyingStorage.clear(); } } Here is how I tried to create a test/mock : public class CacheTest extends TestCase { private Mockery context; private Map mockMap; private Cache cache; @Override @Before public void setUp() { context = new Mockery() { { setImposteriser(ClassImposteriser.INSTANCE); } }; mockMap = context.mock(Map.class); cache = new Cache(mockMap); } public void testCache() { context.checking(new Expectations() {{ atLeast(1).of(mockMap).size(); will(returnValue(int.class)); }}); } } It passes the test and basically does nothing, what I wanted is to create a map and check its size, and you know work some variations try to get a grip on this. Understand better trough examples, what else could I test here or any other exercises would help me a lot. tnx

  • Open source tool for hosting projects similar to "Google Project Hosting"

    - by Jeesmon
    We are looking for open source tool for hosting our internal projects like "Google Project Hosting". The tool should support individual wiki and version control for each project and it should be easy to configure for each project like in google code. We explored trac but seems it lack good support for multiple projects. The tool will be installed in our internal host and cannot use hosted service. A java based tool will be ideal.

  • Iteration order of HashSet

    - by eljenso
    If every object added to a java.util.HashSet implements Object.equals() and Object.hashCode() in a deterministic fashion, is the iteration order over the HashSet guaranteed to be identical for every identical set of elements added, irrespective of the order in which they were added?

  • How to group a database write and spreadsheet write in single "transaction"

    - by WhyGeeEx
    I have a Java program that writes results to both a DB (SQL Server) and a spreadsheet (POI), and it would be best if neither is written to if there's an error with either. It would be a lot worse if the spreadsheet was produced and then an error happened while saving to the DB, so I'm doing the DB-write first. Even so, I'm wondering if someone knows of a way to guarantee they both succeed or fail as a unit. Thanks!

  • How to set Accept-Language header on request from applet

    - by Jo
    Hi, I'm not familiar with Java but I need to make a request to a remote webservice from within my applet. The webservice (.Net 1.1) uses HttpContext.Current.Request.UserLanguages[0] to determine the language to use. But the value of this member is alway null. So is there a way to pass the Accept-Language header along with something like "en-GB" set?

  • Parsing plain text to some structured object

    - by Jeriho
    I am working on parsing plain text and converting it to key-value pairs. For example, plain text: some_uninteresting_thing key1 valueA, valueB, valueC key2 valueD key3 valueE valueF key4 valueG(valueH, valueI) key5 some_uninteresting_thing valueJ some_uninteresting_thing key6 some_uninteresting_thing (key6 shouldn't be mapped because has no appropriate values) As you can see plain text is lenient. What java library can handle this? If no such library exist, any suggestions on algorithm to do this.

  • How to explictely obtain post data in Spring MVC?

    - by predhme
    Is there a way to obtain the post data itself? I know spring handles binding post data to java objects. But if I had two fields that I want to process manually, how do I obtain that data? Assuming I had two fields in my form <input type="text" name="value1" id="value1"/> <input type="text" name="value2" id="value2"/> How would I go about retrieving those values in my controller?

  • Upside down question mark issue

    - by Madhumita
    We have a very strange problem in out application, all of a sudden we started noticing upside down question marks being saved along with other text typed in to the fields on the screen. These upside down question marks were not originally entered by the users and it is unclear where they come from. We are using Oracle 10g with java. And this is happening, even when no data is copied from Microsoft Word
