  • IE6 PNG-transparency CSS hack not working

    - by John
    I looked around and decided to use a CSS approach rather than rely on JS... I figure the kind of corporate users stuck with IE6 might also have JS disabled by IT departments. So In my HTML I have: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <meta http-equiv="Content-Type" content="text/html;charset=utf-8" /> <title>My Page</title> <link rel="stylesheet" type="text/css" href="default.css" /> <!--[if IE 6]><link rel="stylesheet" type="text/css" href="ie6.css"><![endif]--> </head> <body> <img src="media/logo.png"/> </body> Then my ie6.css consists simply of: img { filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(...); } However none of this makes the slightest difference, no transparency. I commented out all the rest of the page so it is literally that one and still no luck. I removed the default.css stylesheet and still no difference.

  • problem parsing with XMLReader (using ReadSubTree)

    - by no9
    Hello. Im trying to build a simple XML to Controls parser in my CF application. In the code below the string im trying to parse looks like this: "<Panel><Label>Text1</Label><Label>Text2</Label></Panel>" The result i want with this code would be a Panel with two labels. But the problem is when the first Label is parsed the subreader.Read() returns false in the ParsePanelElementh method, and so it falls out of while statement. Since im new into XMLReader i must be missing something very simple. Any help would be apreciated ! peace. static class XMLParser { public static Control Parse(string aXmlString) { XmlReader reader = XmlReader.Create(new StringReader(aXmlString)); return ParseXML(reader); } public static Control ParseXML(XmlReader reader) { using (reader) { while (reader.Read()) { if (reader.NodeType == XmlNodeType.Element) { if (reader.LocalName == "Panel") { return ParsePanelElement(reader); } if (reader.LocalName == "Label") { return ParseLabelElement(reader); } } } } return null; } private static Control ParsePanelElement(XmlReader reader) { var myPanel = new Panel(); XmlReader subReader = reader.ReadSubtree(); while (subReader.Read()) { Control subControl = ParseXML(subReader); if (subControl != null) { myPanel.Controls.Add(subControl); }; } return myPanel; } private static Control ParseLabelElement(XmlReader reader) { reader.Read(); var myString = reader.Value as string; var myLabel = new Label(); myLabel.Text = myString; return myLabel; } }

  • JAXB does not call setter when unmarshalling objects

    - by Yaneeve
    Hi all, I am using JAXB 2.0 JDK 6 in order to unmarshall an XML instance into POJOs. In order to add some custom validation I have inserted a validation call into the setter of a property, yet despite it being private, it seems that the unmarshaller does not call the setter but directly modifies the private field. It is crucial to me that the custom validation occurs for this specific field every unmarshall call. What should I do? Code: @XmlAccessorType(XmlAccessType.FIELD) @XmlType(name = "LegalParams", propOrder = { "value" }) public class LegalParams { private static final Logger LOG = Logger.getLogger(LegalParams.class); @XmlTransient private LegalParamsValidator legalParamValidator; public LegalParams() { try { WebApplicationContext webApplicationContext = ContextLoader.getCurrentWebApplicationContext(); LegalParamsFactory legalParamsFactory = (LegalParamsFactory) webApplicationContext.getBean("legalParamsFactory"); HttpSession httpSession = SessionHolder.getInstance().get(); legalParamValidator = legalParamsFactory.newLegalParamsValidator(httpSession); } catch (LegalParamsException lpe) { LOG.warn("Validator related error occurred while attempting to construct a new instance of LegalParams"); throw new IllegalStateException("LegalParams creation failure", lpe); } catch (Exception e) { LOG.warn("Spring related error occurred while attempting to construct a new instance of LegalParams"); throw new IllegalStateException("LegalParams creation failure", e); } } @XmlValue private String value; /** * Gets the value of the value property. * * @return * possible object is * {@link String } * */ public String getValue() { return value; } /** * Sets the value of the value property. * * @param value * allowed object is * {@link String } * @throws TestCaseValidationException * */ public void setValue(String value) throws TestCaseValidationException { legalParamValidator.assertValid(value); this.value = value; } }

  • best practice for boolean REST results

    - by Andrew Patterson
    I have a resource /system/resource And I wish to ask the system a boolean question about the resource that can't be answered by processing on the client (i.e I can't just GET the resource and look through the actual resource data - it requires some processing on the backend using data not available to the client). eg /system/resource/related/otherresourcename I want this is either return true or false. Does anyone have any best practice examples for this type of interaction? Possibilities that come to my mind: use of HTTP status code, no returned body (smells wrong) return plain text string (True, False, 1, 0) - Not sure what string values are appropriate to use, and furthermore this seems to be ignoring the Accept media type and always returning plain text come up with a boolean object for each of my support media types and return the appropriate type (a JSON document with a single boolean result, an XML document with a single boolean field). However this seems unwieldy. I don't particularly want to get into a long discussion about the true meaning of a RESTful system etc - I have used the word REST in the title because it best expresses the general flavour of system I am designing (even if perhaps I am tending more towards RPC over the web rather than true REST). However, if someone has some thoughts on how a true RESTful system avoids this problem entirely I would be happy to hear them.

  • Compiling and linking libcurl to create a stand alone dll

    - by Haraldo
    Hi, I've managed to compile a dll with the necessary linked libraries (*.lib) and with CURL_STATICLIB set in the preprocessor section among other settings. I'm using "libcurl-7.19.3-win32-ssl-msvc.zip" package and compiling with VS 2008 express. This has been the first version I managed to get compiled properly with no link issues etc. The problem I have now is that my dll needs libcurl.dll to function and this is not ok. My dll needs to be independent. I have no idea how to implement this. I've taken all day just to get what I've got compiled. I've got runtime library set to Multi threaded dll (debug/release) respectively under C/C++ - code generation. I've a number of preprocessor set - CURL_STATICLIB being one of them. Configuration Type is set to Dynamic Library Use of MFC is set to Use MFC in a static library Additional Library Directories is set to the lib folders (debug/release) respectively. I've noticed there is a curllib_static.lib file which I've tried instead of curllib.lib as an additional dependency but it only compiles with the later. This is driving me nuts! So I guess I need some guidance as to how to make my dll completely static so it doesn't have any dependencies. I notice my dll is currently dependent on: CURLLIB.DLL MSVCR90D.DLL As I'm pretty new to C++ it could be a setting I'm missing in VS 2008 but I'm not sure. One person said I should be using a static library with *.a files (libcurl.a) etc but when I do this I get link errors which I haven't been able to resolve. Any guidance here would be much appreciated.

  • How can I choose different hints for different joins for a single table in a query hint?

    - by RenderIn
    Suppose I have the following query: select * from A, B, C, D where A.x = B.x and B.y = C.y and A.z = D.z I have indexes on A.x and B.x and B.y and C.y and D.z There is no index on A.z. How can I give a hint to this query to use an INDEX hint on A.x but a USE_HASH hint on A.z? It seems like hints only take the table name, not the specific join, so when using a single table with multiple joins I can only specify a single strategy for all of them. Alternative, suppose I'm using a LEADING or ORDERED hint on the above query. Both of these hints only take a table name as well, so how can I ensure that the A.x = B.x join takes place before the A.z = D.z one? I realize in this case I could list D first, but imagine D subsequently joins to E and that the D-E join is the last one I want in the entire query. A third configuration -- Suppose I want the A.x join to be the first of the entire query, and I want the A.z join to be the last one. How can I use a hint to have a single join from A to take place, followed by the B-C join, and the A-D join last?

  • vb.net, How can I limit a textchanged event for a textbox to keyboard input only?

    - by Luay
    Hi everyone, Please allow me to explain what I have and what I am trying to achieve. I have a textbox (called txtb1) and a button under it (called btn_browse) on a winform in a vb.net project. When the user clicks the button a folder browser dialog appears. The user selects his desired folder and when he/she clicks 'ok' the dialog closes and the path of the folder selected appears in the textbox. I also want to store that value in a variable to be used somewhere else(the value will be copied to an xml file when the user clicks 'apply' on the form, but this has no effect nor is related to my problem). To achieve that I have the following code: Public myVar As String Private Sub btn_browse_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btn_browse.Click Dim f As New FolderBrowserDialog If f.ShowDialog() = DialogResult.OK Then txtb1.Text = f.SelectedPath End If myVar = txtb1.text f.Dispose() End Sub This part works with no problems. Now, what if the user either: 1- decides to enter the path manually rather than use the browse button. or, 2- after using the browse button and selecting the folder they decide to manually change the location In trying to solve this I added a textchanged event to the textbox as follows: Private Sub txtb1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles txtb1.TextChanged myVar = txtb1.Text End Sub However, this is not working. Apparently, and I don't know if this is relevant, when the user selects the desired folder using the browse button the textchanged event is also triggered. and when I click on the textbox (to give it focus) and press any keyboard key the application simply stops responding. So my questions are: am I going about this the right way? if my logic is flawed, could someone point me to how usually such a thing could be achieved? is it possible to limit the triggering events to only keyboard input as a way around this? I tried the keydown and keypress events but I am getting the freeze. I would be grateful for your help. Thanks

  • Getting a "No default module defined for this application" exception while running controller unit t

    - by Doron
    I have an application with the default directory structure, for an application without custom modules (see structure figure at the end). I have written a ControllerTestCase.php file as instructed in many tutorials, and I've created the appropriate bootstrap file as well (once again, see figures at the end).

  • GET params in ruby-on-rails project - best practices?

    - by Lynn C
    I've inherited a little rails app and I need to extend it slightly. It's actually quite simple, but I want to make sure I'm doing it the right way... If I visit myapp:3000/api/persons it gives me a full list of people in XML format. I want to pass param in the URL so that I can return users that match the login or the email e.g. yapp:3000/api/persons?login=jsmith would give me the person with the corresponding login. Here's the code: def index if params.size > 2 # We have 'action' & 'controller' by default if params['login'] @person = [Person.find(:first, :conditions => { :login => params['login'] })] elsif params['email'] @persons = [Person.find(:first, :conditions => { :email => params['email'] })] end else @persons = Person.find(:all) end end Two questions... Is it safe? Does ActiveRecord protect me from SQL injection attacks (notice I'm trusting the params that are coming in)? Is this the best way to do it, or is there some automagical rails feature I'm not familiar with?

  • Unhandled exception when DataTemplate created dynamically using Silverlight 3.0

    - by user333397
    Requirement is to create a reusable multi-select combobox custom control. To accomplish this, I am creating the DataTemplate dynamically through code and set the combobox ItemTemplate. I am able to load the datatemplate dynamically and set the ItemTemplate, but getting unhandled exception (code: 7054) when we select the combobox.

  • How to map different UI views in a RESTful web application?

    - by MicE
    Hello, I'm designing a web application, which will support both standard UIs (accessed via browsers) and a RESTful API (an XML/JSON-based web service). User agents will be able to differentiate between these by using different values in the Accept HTTP header. The RESTful API will use the following URI structure (example for an "article" resource): GET /article/ - gets a list of articles POST /article/ - adds a new article PUT /article/{id} - updates an existing article based on {id} DELETE /article/{id} - deletes an existing article based on {id} The UI part of the application will however need to support multiple views, for example: a standard resource view a view for submitting a new resource a view for editing an existing resource a view for deleting an existing resource (i.e. display delete confirmation) Note that the latter three views are still accessed via GET, even though they are processed via overloaded POST. Possible solution: Introduce additional parameters (keywords) into URIs which would identify individual views - i.e. on top of the above, the application would support the following URIs (but only for Content-Type: text/html): GET /article/add - displays a form for adding a new article (fetched via GET, processed via POST) GET /article/123 - displays article 123 in "view" mode (fetched via GET) GET /article/123/edit - displays article 123 in "edit" mode (fetched via GET, processed via PUT overloaded as POST) GET /article/123/delete - displays "delete" confirmation for article 123 (fetched via GET, processed via DELETE overloaded as POST) A better implementation of the above might be to put the add/edit/delete keywords into a GET parameter - since they do not change the resource we're working with, it might be better to keep the base URI same for all of them. My question is: How would you map the above URI structure to UIs served to the regular user, considering that there can be several views per each resource, please? Do you agree with the possible solution detailed above, or would you recommend a different approach based on your experience? NB: we've already implemented an application which consists of a standalone RESTful API and a standalone web application. I'm currently looking into options for future projects where these two would be merged together (i.e. in order to reduce overhead). Thank you, M.

  • How do I use foreach with QDomNodeList in Qt?

    - by Venemo
    Hi Everyone, I'm new to Qt and I'm learning something new every day. Currently, I'm developing a small application for my Nokia N900 in my free time. Everything is fine, I am able to compile and run Maemo applications on the device. I've just learned about the foreach keyword in Qt. (I know it is not in C++, so I didn't think about it until I accidentally stumbled upon a Qt doc that mentioned it.) So, I decided to change my quite annoying and unreadable loops to foreach, but I failed with this: QDomNodeList list = doc.lastChild().childNodes().at(1).firstChild().childNodes(); for (int x = 0; x < list.count(); x++) { QDomElement node = list.at(x).toElement(); // Do something with node } This is how I tried: foreach (QDomElement node, doc.lastChild().childNodes().at(1).firstChild().childNodes()) { // Do something with node } For some reason the above code doesn't even compile. I get cryptic error messages from the compiler. Could someone please explain to me how to get it right? If the foreach loop doesn't support QDomNodeList, is there a way of handling XML files that do support foreach?

  • PHP and CURL under Windows 7 64 bits and Apache

    - by supermogx
    I'm trying to use curl with PHP on my box without any success. My Config : OS : win 7 64 bits, PHP : 5.3.1, Apache : 2.2.14 I was able to use the mysql extension, so the configuration of my php.ini seems fine. But I get and error in Apache log with curl : PHP Warning: PHP Startup: Unable to load dynamic library 'C:/php-5.3.1/ext/php_curl.dll' - The specified module could not be found.\r\n in Unknown on line 0 The file is right there, and it's loading php_mysql.dll without any problem. I tried everything : to put the dll file in apache\bin, windows\system32, put the path of the php EXT in the PATH environment variable. to put some lib (libeay.dll and sssomething.dll) in windows 32 Well, I think this might have something to do with my Windows being 64 bits or with the version of PHP.. maybe. I don't know anymore :( Any idea? Update I'm not using Wamp because I like to know what I do to my system, and ultimately choose the version that I want of apache, php and MySql. My Solution I added the path of PHP in my PATH environement variable and it worked. I'll try to find out what was the DLL needed. Update : Well it looks like it was libeay32.dll and sslleay32.dll had to be in the PATH environment variable. I added to the bin subdirectory of Apache and it worked.

  • Building an extension framework for a Rails app

    - by obvio171
    I'm starting research on what I'd need in order to build a user-level plugin system (like Wordpress plugins) for a Rails app, so I'd appreciate some general pointers/advice. By user-level plugin I mean a package a user can extract into a folder and have it show up on an admin interface, allowing them to add some extra configuration and then activate it. What is the best way to go about doing this? Is there any other opensource project that does this already? What does Rails itself already offer for programmer-level plugins that could be leveraged? Any Rails plugins that could help me with this? A plugin would have to be able to: run its own migrations (with this? it's undocumented) have access to my models (plugins already do) have entry points for adding content to views (can be done with content_for and yield) replace entire views or partials (how?) provide its own admin and user-facing views (how?) create its own routes (or maybe just announce its presence and let me create the routes for it, to avoid plugins stepping on each other's toes) Anything else I'm missing? Also, is there a way to limit which tables/actions the plugin has access to concerning migrations and models, and also limit their access to routes (maybe letting them include, but not remove routes)? P.S.: I'll try to keep this updated, compiling stuff I figure out and relevant answers so as to have a sort of guide for others.

  • Ruby custom class to and from YAML;

    - by Sanarothe
    Hi. I'm having trouble deserializing a ruby class that I wrote to YAML. Where I want to be I want to be able to pass one object around as a full 'question' which includes the question text, some possible answers (For multi. choice) and the correct answer. One module (The encoder) takes input, builds a 'question' class out of it and appends it to the question pool. Another module reads a question pool and builds an array of 'question' objects. Where I am currently Sample Question Pool --- | --- !ruby/object:MultiQ a: "no" answer: "no" b: "no" c: "no" d: "no" text: "yes?" Encoder dump to YAML file. Object is a MultiQ filled up with input.

I am setting the current ccnet.config <sourcecontrol type="svn"> <trunkUrl>https://bladerunner.azullo.local:8443/svn/application/trunk</trunkUrl> <executable>C:\Program Files (x86)\VisualSVN Server\bin\svn.exe</executable> <username>test</username> <password>test</password> <workingDirectory>D:\Development\Build\application\</workingDirectory> </sourcecontrol> <publishers> <xmllogger/> </publishers> <modificationDelaySeconds>10</modificationDelaySeconds> </project> When I run this I expect it to go to https://bladerunner.azullo.local:8443/svn/application/trunk, however i get the following ThoughtWorks.CruiseControl.Core.CruiseControlException: Source control operation failed: svn: OPTIONS of 'http://bladerunner.azullo.local:8080/svn/application/trunk': could not connect to server (http://bladerunner.azullo.local:8080) . Process command: C:\Program Files (x86)\VisualSVN Server\bin\svn.exe update D:\Development\build\application\ --username test --password ** --no-auth-cache --non-interactive at ThoughtWorks.CruiseControl.Core.Sourcecontrol.ProcessSourceControl.Execute(ProcessInfo processInfo) at ThoughtWorks.CruiseControl.Core.Sourcecontrol.Svn.UpdateSource(IIntegrationResult result) at ThoughtWorks.CruiseControl.Core.IntegrationRunner.Build(IIntegrationResult result) at ThoughtWorks.CruiseControl.Core.IntegrationRunner.Integrate(IntegrationRequest request) So for some reason it goes to 'http://bladerunner.azullo.local:8080/svn/application/trunk' If I remove the username and password elements in the ccnet.config. It goes to the correct url. I dont understand this behaviour. I have configured visual svn with a certificate using Active directory Certificate Services, if this was the problem I would expect it to show an error regarding the certificate instead of changing the url. I have cleared our state etc Any Ideas

  • HTML Doctype Setting / IE Quirks Mode

    - by Frederico
    I'm working within the parameters of an un-reachable developer, whom has created an html generation system for our products.. Whenever a new page is generated he places: <!-- updated page at 05/MAY/2010 02:58.58 --> <!-- You must use the template manager to modify the formatting of this page. --> resulting in my code looking like: <!-- updated page at 05/MAY/2010 02:55.30 --> <!-- You must use the template manager to modify the formatting of this page. --> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html lang="en" xmlns="http://www.w3.org/1999/xhtml" xml:lang="en"> I don't believe IE read's this doctype at all, as when looking at the developer screen, it renders in Quirks mode... is there any other way to force IE out of this horrible Quirks mode? I've been trying to reach the developer but he has been rather un-available.. Thank you in advance for any help you might have to offer.

  • Can FluentNHibernate be used with .Net4?

    - by stiank81
    I have a WPF application running with .Net3.5 using FluentNHibernate, and all works fine. When I upgraded to VS2010 I ran into some odd problems, but after changing to use x64 variant of SQLite it worked fine again. Now I want to change to use .Net4, but this has turned into a more painful experience then I expected.. First I met a problem which required that I set a [SecurityCritical] attribute. Fine - I fixed this. But the reason this was exposed was because an exception was thrown in the first place. And the exception thrown was the following - when calling FluentConfiguration.BuildConfiguration: FluentConfigurationException unhandled An invalid or incomplete configuration was used while creating a SessionFactory. Check PotentialReasons collection, and InnerException for more detail The inner exception gives us more information: Message = "Could not create the driver from NHibernate.Driver.SQLite20Driver, NHibernate, Version=2.1.2.4000, Culture=neutral, PublicKeyToken=aa95f207798dfdb4." This is what I saw in my own project when moving to VS2010. I have tried changing Fluent to use the x64 variant of SQLite, but this doesn't change anything. Does it sound like it might be related to mixing of 32bit and 64bit assemblies? I see that there are also others that have seen this problem, but I haven't really seen any solution yet. Anyone out there using Fluent with .Net4 and SQLite - on a 64bit machine - successfully? Help! I'm lost...

  • Send parameters to a web service.

    - by Alejandra Meraz
    Before I start: I'm programming for Iphone, using objective C. I have already implemented a call to a web service function using NSURLRequest and NSURLConnection. The function then returns a XML with the info I need. The code is as follows: NSURL *url = [NSURL URLWithString:@"http://myWebService/function"]; NSMutableURLRequest theRequest = [[NSMutableURLRequest alloc] initWithURL:url]; NSURLConnection theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self]; i also implemented the methods didRecieveResponse didRecieveAuthenticationChallenge didRecievedData didFailWithError connectionDidFinishLoading. And it works perfectly. Now I need to send 2 parameters to the function: "location" and "module". I tried using the following modification: NSMutableURLRequest theRequest = [[NSMutableURLRequest alloc] initWithURL:url]; [theRequest setValue:@"USA" forHTTPHeaderField:@"location"]; [theRequest setValue:@"DEVELOPMENT" forHTTPHeaderField:@"module"]; NSURLConnection theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self]; But it doesn't seem to work. I'm doing something wrong? is there a way to know if I'm using the wrong names for the parameters (as maybe it is "Location" or "LOCATION" or it doesn't matter?)? or a way to know which parameters is the function waiting for... Extra info: I don't have access to the source of the web service so I can't modify it. But I can access the WSDL. The person who made the function say is all there... but I can't make any sense of it .< Any help would be appreciated. :)

  • Learning Hibernate: too many connections

    - by stivlo
    I'm trying to learn Hibernate and I wrote the simplest Person Entity and I was trying to insert 2000 of them. I know I'm using deprecated methods, I will try to figure out what are the new ones later. First, here is the class Person: @Entity public class Person { private int id; private String name; @Id @GeneratedValue(strategy = GenerationType.TABLE, generator = "person") @TableGenerator(name = "person", table = "sequences", allocationSize = 1) public int getId() { return id; } public void setId(int id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } } Then I wrote a small App class that insert 2000 entities with a loop: public class App { private static AnnotationConfiguration config; public static void insertPerson() { SessionFactory factory = config.buildSessionFactory(); Session session = factory.getCurrentSession(); session.beginTransaction(); Person aPerson = new Person(); aPerson.setName("John"); session.save(aPerson); session.getTransaction().commit(); } public static void main(String[] args) { config = new AnnotationConfiguration(); config.addAnnotatedClass(Person.class); config.configure("hibernate.cfg.xml"); //is the default already new SchemaExport(config).create(true, true); //print and execute for (int i = 0; i < 2000; i++) { insertPerson(); } } } What I get after a while is: Exception in thread "main" org.hibernate.exception.JDBCConnectionException: Cannot open connection Caused by: com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: Too many connections Now I know that probably if I put the transaction outside the loop it would work, but mine was a test to see what happens when executing multiple transactions. And since there is only one open at each time, it should work. I tried to add session.close() after the commit, but I got Exception in thread "main" org.hibernate.SessionException: Session was already closed So how to solve the problem?

  • Why does 12:20 PM parse to 0:20 on the next day?

    - by Hanno Fietz
    I'm using java.text.SimpleDateFormat to parse string representations of date/time values inside an XML document. I'm seeing all times that have an hour value of 12 shifted by 12 hours into the future, i. e. 20 minutes past noon gets parsed to mean 20 minutes past midnight the following day. I wrote a unit test which seems to confirm that the error is made upon parsing (I checked the return values from getTime() with the linux shell command date). Now I'm wondering: is there a bug in the parse() method? is there something wrong with the input string? am I using the wrong format string for the input? The input data is taken from Yahoo's YWeather service. Here's the test and its output: public class YWeatherReaderTest { public static final String[] rgDateSamples = { "Thu, 08 Apr 2010 12:20 PM CEST", "Thu, 08 Apr 2010 12:20 AM CEST" }; public void dateParsing() throws ParseException { DateFormat formatter = new SimpleDateFormat("EEE, dd MMM yyyy K:m a z", Locale.US); for (String dtsSrc : YWeatherReaderTest.rgDateSamples) { Date dt = formatter.parse(dtsSrc); String dtsDst = formatter.format(dt); System.out.println(dtsSrc); System.out.println(dtsDst); System.out.println(); } } } Thu, 08 Apr 2010 12:20 PM CEST Fri, 09 Apr 2010 0:20 AM CEST Thu, 08 Apr 2010 12:20 AM CEST Thu, 08 Apr 2010 0:20 PM CEST The second output line of the second iteration is slightly weird, because 00:20 isn't PM. The milliseconds value of the Date object, however, corresponds to the (wrong) time of 20 minutes past noon.
