  • Migrating from hand-written persistence layer to ORM

    - by Sergey Mikhanov
    Hi community, We are currently evaluating options for migrating from hand-written persistence layer to ORM. We have a bunch of legacy persistent objects (~200), that implement simple interface like this: interface JDBC { public long getId(); public void setId(long id); public void retrieve(); public void setDataSource(DataSource ds); } When retrieve() is called, object populates itself by issuing handwritten SQL queries to the connection provided using the ID it received in the setter (this usually is the only parameter to the query). It manages its statements, result sets, etc itself. Some of the objects have special flavors of retrive() method, like retrieveByName(), in this case a different SQL is issued. Queries could be quite complex, we often join several tables to populate the sets representing relations to other objects, sometimes join queries are issued on-demand in the specific getter (lazy loading). So basically, we have implemented most of the ORM's functionality manually. The reason for that was performance. We have very strong requirements for speed, and back in 2005 (when this code was written) performance tests has shown that none of mainstream ORMs were that fast as hand-written SQL. The problems we are facing now that make us think of ORM are: Most of the paths in this code are well-tested and are stable. However, some rarely-used code is prone to result set and connection leaks that are very hard to detect We are currently squeezing some additional performance by adding caching to our persistence layer and it's a huge pain to maintain the cached objects manually in this setup Support of this code when DB schema changes is a big problem. I am looking for an advice on what could be the best alternative for us. As far as I know, ORMs has advanced in last 5 years, so it might be that now there's one that offers an acceptable performance. As I see this issue, we need to address those points: Find some way to reuse at least some of the written SQL to express mappings Have the possibility to issue native SQL queries without the necessity to manually decompose their results (i.e. avoid manual rs.getInt(42) as they are very sensitive to schema changes) Add a non-intrusive caching layer Keep the performance figures. Is there any ORM framework you could recommend with regards to that?

  • Programmatically access currency exchange rates

    - by Adam Pierce
    I'm setting up an online ordering system but I'm in Australia and for international customers I'd like to show prices in US dollars or Euros so they don't have to make the mental effort to convert from Australian dollars. Does anyone know if I can pull up to date exchange rates off the net somewhere in an easy-to-parse format I can access from my PHP script ? UPDATE: I have now written a PHP class which implements this. You can get the code from my website.

  • What are the advantages and disadvantages of a web site that contains a single page ?

    - by Misha Moroshko
    I would like to code a little web site that will contain several sections like "Home", "Gallery", "Contact Us", "FAQs", and so on. I thought to do this in one HTML by putting each section in a div and show only one div per time (using Javascript / jQuery), based on the chosen menu button. Alternatively, I could create a separate HTML page per section, and link these pages to the menu buttons. What are the advantages and disadvantages of these two methods ?

  • How can I stop cruise control re-building after a failed build?

    - by RodeoClown
    I got back from the weekend to discover that somebody *ahem* had missed a file commit last thing Friday afternoon... Cruise control has been having fun, and tried to re-build every five minutes since then despite no further commits. This means that my colleagues and I have received approximately six hojillion emails from cruise control. A single fail email would be more than enough to notify us. Is there any way to stop cruise control building on failure, at least until a new commit occurs?

  • which should be drawn first , class or sequence diagram?

    - by m0j1
    hi , I've had this discussion with my professor at college about UML diagrams . hi believes that sequence diagrams should be drawn before getting to class diagrams . but I think the opposite . I think after finishing the usecase diagram , the next diagram should be class diagram and after that we should get to sequence diagram . Rational rose requires us to use the classes in sequence diagram, which are already in class diagram . can anyone help me with this? thanks

  • Exploded (unpacked) EAR vs. Packaged EAR file?

    - by Adam
    In my office we use exploded EAR's (and inside them exploded WAR directories) for our test environments, and then a packaged one for production. I've yet to find a good explanation of the reason behind this though. I understand it's easier from a deployment perspective to push out a single file during builds, but it prevents us from doing things like property file changes without doing complete rebuilds (we could skip the compiles, but our environment currently binds the compile and jar processes together). What are the major advantages / disadvantages between these two configurations?

  • iPhone - How do I find the MAC address of the connected WiFi access point?

    - by Ciaran
    Without using the private APIs, is it possible to programatically determine the MAC address of the access point that the iPhone is connected to? I understand that this should be doable using the core BSD libraries, but we are new to this, so it would be great if someone can point us to some starter code. Note: we're trying to determine the MAC address of the remote device - not the MAC address of the iPhone.

    - by Picaro De Vosio
    Hi, Dll best practices document from Microsoft available Here recommends avoiding use of memory management function from the dynamic C Run-Time (CRT) within DllMain. But DllMain function of MFC Extension DLL is dynamically allocating the memory for CDynLinkLibrary in the code snippet available at MSDN "http://msdn.microsoft.com/en-us/library/1btd5ea3%28v=VS.80%29.aspx". Is it a violation of Dll Best Practices or ok to use in MFC extension DLL? thanks

  • How to convert a fixed height/width-fixed layout to elastic?

    - by phretor
    I used the same software used here http://us.gn.bartal.org/ to create a fixed width/height treemap in HTML + CSS. I would like to make it elastic by having a JavaScript function to convert all pixels absolute positions and sizes to percentages. How would you suggest to proceed? Is there some jQuery/Prototype/Dojo magic that I can exploit?

  • ASP.NET - What happens when a HttpCookie expiration has been crossed

    - by user70192
    Hello, I am creating some cookies in my ASP.NET application. These cookies expire 10 minutes after they have been created. I follow the approach described on MSDN as shown here: http://msdn.microsoft.com/en-us/library/system.web.httpcookie.expires.aspx My question is, when a cookie "expires", what happens? Does the browser automatically delete the cookie? Is it our responsibility as developers to remove the cookies if they exist and have expired? Thank you,

  • CDN with South America peering points / edge nodes

    - by Bill
    Hello, Does anyone one know of a CDN (Content Delivery Network) with true South American peering points or edge nodes? This seems to be quite rare. It seems that most CDNs serve Central and South America from Texas. However, our application requires low latency in Brazil, so this is not a good solution for us. We would like to avoid having to set up servers in South America just for this piece of the application, but may end up doing that. Thanks, Bill

  • reCaptcha integration with php

    - by Neil Bradley
    Hi there, I'm building a contact us page that also uses a reCaptcha, but im having a few issues with it. I fill in all of the fields in the contact form and the correct reCaptcha words, but the form does not submit. I'm assuming this is something to do with the validation, but wondered if someone might be able to spot where i'm going wrong? The PHP code at the top of my page looks like this; <?php include('includes/session.php'); $err = ''; $success = ''; if(isset($_POST["docontact"]) && $_POST["docontact"] == "yes") { //get form details $form = new stdClass(); $form->name = sanitizeOne($_POST["name"], "str"); $form->email = sanitizeOne($_POST["email"], "str"); $form->phone = sanitizeOne($_POST["phone"], "str"); $form->mysevenprog = sanitizeOne($_POST["mysevenprog"], "str"); $form->enquiry = sanitizeOne($_POST["enquiry"], "str"); $form->howfindsite = sanitizeOne($_POST["howfindsite"], "str"); //Check for errors (required: name, email, enquiry) if($form->name == "") { $err .= '<p class="warning">Please enter your name!</p>'; } if($form->email == "") { $err .= '<p class="warning">Please enter your email address!</p>'; } if($form->enquiry == "") { $err .= '<p class="warning">Please supply an enquiry message!</p>'; } //Send Email if($err == "") { $mailer = new BlueMailer(); $mailer->AddAddress(Configuration::getVar("developer_email"), Configuration::getVar("admin_email_name")); include('templates/email/contact-us-admin.php'); if(!$mailer->Send()) { $err .= "<p>There was an error sending submitting your request!, Please try again later."; } else { $success = 'thanks'; } } } else { //Initialise empty variables $form = new stdClass(); $form->name = ""; $form->email = ""; $form->phone = ""; $form->mysevenprog = ""; $form->enquiry = ""; $form->howfindsite = ""; } ?> And then in the body of my page I have the form as follows; <?php if($err != "") : ?> <div class="error"> <?php echo $err; ?> </div> <?php endif; ?> <?php if($success == 'thanks') : ?> <h3>Thank you for your enquiry</h3> <p>Your enquiry has been successfully sent.
