• Suggestions for connecting .NET WPF GUI with Java SE Server aoo

  - by Sam Goldberg

  BACKGROUND We are building a Java (SE) trading application which will be monitoring market data and sending trade messages based on the market data, and also on user defined configuration parameters. We are planning to provide the user with a thin client, built in .NET (WPF) for managing the parameters, controlling the server behavior, and viewing the current state of the trading. The client doesn't need real-time updates; it will instead update the view once every few seconds (or whatever interval is configured by the user). The client has about 6 different operations it needs to perform with the server, for example: CRUD with configuration parameters query subset of the data receive updates of current positions from server It is possible that most of the different operations (except for receiving data) are just different flavors of managing the configuration parameters, but it's too early in our analysis for us to be sure. To connect the client with the server, we have been considering using: SOAP Web Service RESTful service building a custom TCP/IP based API (text or xml) (least preferred - but we use this approach with other applications we have) As best as I understand, pros and cons of the different web service flavors are: SOAP pro: totally automated in .NET (and Java), modifying server side interface require no code changes in communication layer, just running refresh on Web Service reference to regenerate the classes. con: more overhead in the communication layer sending more text, etc. We're not using J2EE container so maybe doesn't work so well with J2SE REST pro: lighter weight, less data. Has good .NET and Java support. (I don't have any real experience with this, so don't know what other benefits it has.) con: client will not be automatically aware if there are any new operations or properties added (?), so communication layer needs to be updated by developer if server interface changes. con: (both approaches) Server cannot really push updates to the client at regular intervals (?) (However, we won't mind if client polls the server to get updates.) QUESTION What are your opinions on the above options or suggestions for other ways to connect the 2 parts? (Ideally, we don't want to put much work into the communication layer, because it's not the significant part of the application so the more off-the-shelf and automated the better.)

• Zend: Fetching row from session db table after generating session id

  - by Nux

  Hi, I'm trying to update the session table used by Zend_Session_SaveHandler_DbTable directly after authenticating the user and writing the session to the DB. But I can neither update nor fetch the newly inserted row, even though the session id I use to check (Zend_Session::getId()) is valid and the row is indeed inserted into the table. Upon fetching all session ids (on the same request) the one I newly inserted is missing from the results. It does appear in the results if I fetch it with something else. I've checked whether it is a problem with transactions and that does not seem to be the problem - there is no active transaction when I'm fetching the results. I've also tried fetching a few seconds after writing using sleep(), which doesn't help. $auth->getStorage()->write($ident); //sleep(1) $update = $this->db->update('session', array('uid' => $ident->user_id), 'id='.$this->db->quote(Zend_Session::getId())); $qload = 'SELECT id FROM session'; $load = $this->db->fetchAll($qload); echo $qload; print_r($load); $update fails. $load doesn't contain the row that was written with $auth-getStorage()-write($identity). $qload does contain the correct query - copying it to somewhere else leads to the expected result, that is the inserted row is included in the results. Database used is MySQL - InnoDB. If someone knows how to directly fix this (i.e. on the same request, not doing something like updating after redirecting to another page) without modifying Zend_Session_SaveHandler_DbTable: Thank you very much!

• How to Schedule Backups with SQL Server Express

  - by The Official Microsoft IIS Site

  Microsoft’s SQL Server Express is a fantastic product for anyone needing a relational database on a limited budget. By limited budget I’m talking free. Yes SQL Server Express is free but it comes with a few limitations such as only utilizing 1 GB of RAM, databases are limited to 10 GB, and it does not include SQL Profiler. For low volume sites that do not need enterprise level capabilities, this is a compelling solution. Here is a complete SQL Server feature comparison of all the SQL Server...(read more)

For example, I sent these parameters: id = 1 (GET) name = 'John' (GET) surname = 'Smith' (GET) Example $request = $this->getRequest(); echo $request->getParam[0]; // Will output 1 echo $request->getParam[1]; // Will output 'John' echo $request->getParam[2]; // Will output 'Smith' Thank you!

• how to get last inserted id - zend

  - by Lemon

  I'm trying to get latest inserted id from a table using this code: $id = $tbl->fetchAll (array('public=1'), 'id desc'); but it's always returning "1" any ideas? update: I've just discovered toArray();, which retrieves all the data from fetchAll. The problem is, I only need the ID. My current code looks like this: $rowsetArray = $id->toArray(); $rowCount = 1; foreach ($rowsetArray as $rowArray) { foreach ($rowArray as $column => $value) { if ($column="id") {$myid[$brr] = $value;} //echo"\n$myid[$brr]"; } ++$rowCount; ++$brr; } Obviously, I've got the if ($column="id") {$myid[$brr] = $value;} thing wrong. Can anyone point me in the right direction? An aternative would be to filter ID's from fetchAll. Is that possible?

• zend framework can't find Model classes ?

  - by user284503

  Yall: I have a simple question, it might be a simple configuration issue, but I have a Model defined, and when I try to access it from a controller it fails. The Model is in the model directory, and when I look at the quickstart app, it seems like this should work. Here is my model: <?php class Application_Model_User { protected $_user; protected $_password; protected $_userId; // very simple right } ?> My controller just stops.. here is the controller code: <?php class UserController extends Zend_Controller_Action { public function init() { } public function indexAction() { // display login form $users = new Application_Model_User(); echo "test never echos.. stopped above ? weird huh.."; // fails before .. } ?> Thank you everyone,

• Draw text on a loaded pdf file with Zend Framework

  - by Rick de Graaf

  Hello, I'm trying to load a existing pdf file, and fill this with database information. Loading the file and everything is working, except for writing data to the loaded page. It doesn't write text to the loaded page. If I add a new page en use a foreach to apply drawing to all pages, all added pages are written, except for the loaded one. Below is the code I'm using: $pdf = Zend_Pdf::load('./documents/agreements/_root/gegevens.pdf'); // Load pdf $pdf->pages = array_reverse($pdf->pages); // reverse pages $pdf->pages[] = new Zend_Pdf_Page(Zend_Pdf_Page::SIZE_A4); // Add a page (A4) $font = Zend_Pdf_Font::fontWithName(Zend_Pdf_Font::FONT_HELVETICA); // Set font foreach($pdf->pages as $page) // Apply settings+text to every page (total of 2) { $page->setFont($font, 36); $page->setAlpha(0.25); $page->drawText('LALALALALALALA', 62, 260, 'UTF-8'); } $pdf->save('./documents/agreements/Gegevens_'.$this->school_id.'.pdf'); // Save file

• Suspend file validation on Zend Framework

  - by dimitris mistriotis

  Hi, Currently on my application I have a form where I ask the user to upload an image file to be used as a logo. I want to allow the user to reset that to nothing by supplying no file (by just pressing the upload button from the browser). In this scenario the only thing left is to suspend file validation when no file is included. Currently I get the *self::NO_FILE* error from the *Zend_Validate_File_Upload* class. Is there any way to suspend the validation so that nothing will be checked if no file has been provided?

• need advice on Zend framework Application architecture, or say approach dealing with modules

  - by simple

  Let me start with the things that I did and how am I using some things to get results I have set up modular structure as: application/ /configs /layouts /models /modules /users /profile /frontend /backend /controllers /views .... I write a plugin that does addes changes with FrontController-setModuleControllerDirectoryName() FrontController-addModuleDirectory() and It is all good I have a changed all the directories according weather admin page is requested in the url or not (it is some thing like /admin/some/some) Let's say I have a single layout for anything that is related to Profile viewing , in this case the "Profile" module. The Profile layout is divided into three parts In the layout I was pulling out the Profile/PhotoController 's index action with a action() $this->action('index', 'photo', 'profile'); Then I have faced few issues 1. Can get passed Params inside the Photo Controller when calling ( profile/profile/index); 2. found out that helper Action() is evil cause it starts another dispatching loop =) --- and now I am thinking that my approach on plugging in controllers modules into layout also evil =). anyhow how Should I deal with plugging in some controllers (another module controllers) into the layout ?

• Zend framework helper intellisense

  - by Nicky De Maeyer

  Not so much a programming problem, but more a productivity problem. We've got quite a few custom view and action helpers in our project. Working with around 7 programmers. Now when someone, creates a helper or if one would want to use a helper, it all goes through the brokers. This means we do not get intellisense for those helpers, which can be real time consuming, having to go look in the docs or the code files. This is ofcourse true for both build in and custom helpers. Does any1 share this pain? Does any1 have a solution for this?

• Zend Framework Router Getting /module/VALUE/controller/action

  - by cappuccino

  I've been googling around and I can't seem to find anything which explains the use of ZF router well. I've read the documentation on the site, which seems to only talk about re-routing. I am trying to make the format: /module/value/controller/action give /module/controller/action passing on value as a parameter e.g. /store/johnsmithbigsale/home/newstuff would route to /store/home/newstuff passing on johnsmithbigsale as the value to a parameter with a hidden namespace e.g. storeName. Some help would be greatful!

• File Server - Storage configuration: RAID vs LVM vs ZFS something else... ?

  - by privatehuff

  We are a small company that does video editing, among other things, and need a place to keep backup copies of large media files and make it easy to share them. I've got a box set up with Ubuntu Server and 4 x 500 GB drives. They're currently set up with Samba as four shared folders that Mac/Windows workstations can see fine, but I want a better solution. There are two major reasons for this: 500 GB is not really big enough (some projects are larger) It is cumbersome to manage the current setup, because individual hard drives have different amounts of free space and duplicated data (for backup). It is confusing now and that will only get worse once there are multiple servers. ("the project is on sever2 in share4" etc) So, I need a way to combine hard drives in such a way as to avoid complete data loss with the failure of a single drive, and so users see only a single share on each server. I've done linux software RAID5 and had a bad experience with it, but would try it again. LVM looks ok but it seems like no one uses it. ZFS seems interesting but it is relatively "new". What is the most efficient and least risky way to to combine the hdd's that is convenient for my users? Edit: The Goal here is basically to create servers that contain an arbitrary number of hard drives but limit complexity from an end-user perspective. (i.e. they see one "folder" per server) Backing up data is not an issue here, but how each solution responds to hardware failure is a serious concern. That is why I lump RAID, LVM, ZFS, and who-knows-what together. My prior experience with RAID5 was also on an Ubuntu Server box and there was a tricky and unlikely set of circumstances that led to complete data loss. I could avoid that again but was left with a feeling that I was adding an unnecessary additional point of failure to the system. I haven't used RAID10 but we are on commodity hardware and the most data drives per box is pretty much fixed at 6. We've got a lot of 500 GB drives and 1.5 TB is pretty small. (Still an option for at least one server, however) I have no experience with LVM and have read conflicting reports on how it handles drive failure. If a (non-striped) LVM setup could handle a single drive failing and only loose whichever files had a portion stored on that drive (and stored most files on a single drive only) we could even live with that. But as long as I have to learn something totally new, I may as well go all the way to ZFS. Unlike LVM, though, I would also have to change my operating system (?) so that increases the distance between where I am and where I want to be. I used a version of solaris at uni and wouldn't mind it terribly, though. On the other end on the IT spectrum, I think I may also explore FreeNAS and/or Openfiler, but that doesn't really solve the how-to-combine-drives issue.

• How to connect to database on remote server

  - by user137263

  Where there is VPN to remote server and then access to the database via local network interface, how can one establish a remote link between one's computer (with a programme such as Visual Studio 2010) and SQL Server (e.g. 2008 R2) ? Any attempts to create a direct link to the SQL Server are blocked. Whilst the SQL Server can be configured to allow external access, this provides its own host of problems. Any help would be much appreciated.
