  • PDO prepare silently fails

    - by Wabbitseason
    I'm experimenting with PHP's session_set_save_handler and I'd like to use a PDO connection to store session data. I have this function as a callback for write actions: function _write($id, $data) { logger('_WRITE ' . $id . ' ' . $data); try { $access = time(); $sql = 'REPLACE INTO sessions SET id=:id, access=:access, data=:data'; logger('This is the last line in this function that appears in the log.'); $stmt = $GLOBALS['db']->prepare($sql); logger('This never gets logged! :('); $stmt->bindParam(':id', $id, PDO::PARAM_STR); $stmt->bindParam(':access', $access, PDO::PARAM_INT); $stmt->bindParam(':data', $data, PDO::PARAM_STR); $stmt->execute(); $stmt->closeCursor(); return true; } catch (PDOException $e) { logger('This is never executed.'); logger($e->getTraceAsString()); } } The first two log messages always show up, but the third one right after $stmt = $GLOBALS['db']->prepare($sql) never makes it to the log file and there's no trace of an exception either. The sessions db table remains empty. The log message from the _close callback is always present. Here's how I connect to the database: $db = new PDO('mysql:host=' . DBHOST . ';dbname=' . DBNAME, DBUSER, DBPASS); $db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); I have PHP 5.2.10. I tried to simply run $GLOBALS['db']->exec($sql) with a "manually prepared" $sql content, but it still failed silently. The query itself is all right I was able to execute it via the db console.

  • in app purchases question

    - by bdt
    I am looking into the iPhone in app purchased models and need to implement a subscription. Ex content will be available for 24 hours. Now the most important thing is that it needs to be available on all the other devices, so bought on the iPhone, viewable on the iPad. I'm not sure how this works ? I need to store some information on the developer server but is this the transaction id and current date/time so when launching the app on the iPad, you will attempt to buy the content again. Apple will see that this user already bought that and hopefully returns the transaction ID. At that moment I can verify if the time limit it still valid or not. Can anyone confirm this method off working? If this is correct is there a 'renew'?

  • How to change order in ordered+persisted collection?

    - by Jaroslav Záruba
    I just need to change order of items in a (previously persisted) ordered collection... I tried simply passing the re-arranged collection to a setter: after committing a transaction the collection is gone. Then I tried to clear() the existing collection and addAll() afterwards: clear() makes persistent manager to mark all the elements as deleted. (But obviously I would like to be able to work with the collection items in the very transaction.) (The collection is not in a default fetch group, so I tried the above also with the named fetch group added into the fetch plan. No luck.) This must be the most stupid question, but I ran out of ideas and I'm stuck here two days already. I swear I googled. :(

  • Managing logs/warnings in Python extensions

    - by Dimitri Tcaciuc
    TL;DR version: What do you use for configurable (and preferably captured) logging inside your C++ bits in a Python project? Details follow. Say you have a a few compiled .so modules that may need to do some error checking and warn user of (partially) incorrect data. Currently I'm having a pretty simplistic setup where I'm using logging framework from Python code and log4cxx library from C/C++. log4cxx log level is defined in a file (log4cxx.properties) and is currently fixed and I'm thinking how to make it more flexible. Couple of choices that I see: One way to control it would be to have a module-wide configuration call. # foo/__init__.py import sys from _foo import import bar, baz, configure_log configure_log(sys.stdout, WARNING) # tests/test_foo.py def test_foo(): # Maybe a custom context to change the logfile for # the module and restore it at the end. with CaptureLog(foo) as log: assert foo.bar() == 5 assert log.read() == "124.24 - foo - INFO - Bar returning 5" Have every compiled function that does logging accept optional log parameters. # foo.c int bar(PyObject* x, PyObject* logfile, PyObject* loglevel) { LoggerPtr logger = default_logger("foo"); if (logfile != Py_None) logger = file_logger(logfile, loglevel); ... } # tests/test_foo.py def test_foo(): with TemporaryFile() as logfile: assert foo.bar(logfile=logfile, loglevel=DEBUG) == 5 assert logfile.read() == "124.24 - foo - INFO - Bar returning 5" Some other way? Second one seems to be somewhat cleaner, but it requires function signature alteration (or using kwargs and parsing them). First one is.. probably somewhat awkward but sets up entire module in one go and removes logic from each individual function. What are your thoughts on this? I'm all ears to alternative solutions as well. Thanks,

  • Besides EAR and EJB, what do I get from a J2EE app server that I don't get in a servlet container li

    - by dacracot
    We use Tomcat to host our WAR based applications. We are servlet container compliant J2EE applications with the exception of org.apache.catalina.authenticator.SingleSignOn. We are being asked to move to a commercial J2EE application server. The first downside to changing that I see is the cost. No matter what the charges for the application server, Tomcat is free. Second is the complexity. We don't use either EJB nor EAR features (of course not, we can't), and have not missed them. What then are the benefits I'm not seeing? What are the drawbacks that I haven't mentioned? Mentioned were... JTA - Java Transaction API - We control transaction via database stored procedures. JPA - Java Persistence API - We use JDBC and again stored procedures to persist. JMS - Java Message Service - We use XML over HTTP for messaging. This is good, please more!

  • Reading from a oracle temp table in a separate procedure than the one it was populted in

    - by Bob
    I have a 2 stored procedures, the first creates an oracle temp table and the second reads from it. The temp table only has scope for that session. I'm calling the procedures from .Net and the second procedure never returns any results. However if I use the same sprocs and parameters in SQL*Plus it works fine. I've tried creating an Oracle Transaction object and had hoped I'd be able to read the tables in while still using the same transaction - trying to emulate an SQL Plus type of single connection environment. Any ideas what I'm doing wrong??

  • How do i keep my DB and lucene in sync?

    - by acidzombie24
    So i can have a transaction in sql. But i am sure its not a good idea to wait in the middle of a transaction for lucene to finish also i am unsure if lucene is permanently saved in the DB until i do something there. Whats the best way to keep my DB and lucene in sync? I am thinking of adding a lucene_queue in my sql db and everytime i make a change i add it into the queue (removing older queue if any) and delete it once it is done. Is this the best way? Also i am unsure how to make lucene permanently keep the changes i made and how frequent i can/should do it.

  • NonUniqueObjectException during DAO integration test?

    - by HDave
    I have a JPA/Hibernate application and am trying to get it to run against H2 and MySQL. Currently I am using Atomikos for transactions and C3P0 for connection pooling. Despite my best efforts my DAO integration tests are failing with org.hibernate.NonUniqueObjectException. I do tend to re-use the same object (same ID even) over and over for all the different tests and I am sure that is the cause, but I can see in the logs that Spring Test and Atomikos are clearly rolling back the transaction associated with each test method. I would have thought the rollback would have also cleared the persistence context too. On a hunch, I added an a call to dao.clear() at the beginning of the faulty test methods and the problem went away!! Rollback doesn't clear the persistence context...hmmm.... Not sure if this is relevant, but I see a possible autocommit setting problem in the log file: [20100613 23:06:34] DEBUG [main] SessionFactoryImpl.(242) | instantiating session factory with properties: .....edited for brevity.... hibernate.connection.autocommit=true, ....more stuff follows Because I am using connection pooling, I figure that Hibernate is where I'll have to indicate I want autocommit off. I found the autocommit property documented here and I put it in my EntityManagerFactory config as follows: <bean id="myappTestLocalEmf" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"> <property name="persistenceUnitName" value="myapp-core" /> <property name="persistenceUnitPostProcessors"> <bean class="com.myapp.core.persist.util.JtaPersistenceUnitPostProcessor"> <property name="jtaDataSource" ref="myappPersistTestJdbcDataSource" /> </bean> </property> <property name="jpaVendorAdapter"> <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter"> <property name="showSql" value="true" /> <property name="database" value="$DS{hibernate.database}" /> <property name="databasePlatform" value="$DS{hibernate.dialect}" /> </bean> </property> <property name="jpaProperties"> <props> <prop key="hibernate.transaction.factory_class">com.atomikos.icatch.jta.hibernate3.AtomikosJTATransactionFactory</prop> <prop key="hibernate.transaction.manager_lookup_class">com.atomikos.icatch.jta.hibernate3.TransactionManagerLookup</prop> <prop key="hibernate.connection.autocommit">false</prop> <prop key="hibernate.format_sql">true"</prop> <prop key="hibernate.use_sql_comments">true</prop> </property> </bean>

  • PHP PDO close()?

    - by PHPLOVER
    Can someone tell me, when you for example update, insert, delete.. should you then close it like $stmt->close(); ? i checked php manual and don't understand what close() actually does. EXAMPLE: $stmt = $dbh->prepare("SELECT `user_email` FROM `users` WHERE `user_email` = ? LIMIT 1"); $stmt->execute(array($email)); $stmt->close(); Next part of my question is, if as an example i had multiple update queries in a transaction after every execute() for each query i am executing should i close them individually ? ... because it's a transaction not sure i need to use $stmt->close(); after each execute(); or just use one $stmt->close(); after all of them ? Thanks once again, phplover

  • Jqyery Bugs?? Long decimal number after two numbers multiply...

    - by Jerry
    Hi all I am working on a shopping site and I am trying to calculate the subtotal of products. I got my price from a array and quantity from getJSON response array. Two of them multiply comes to my subtotal. I can change the quantity and it will comes out different subtotal. However,when I change the quantity to certain number, the final subtotal is like 259.99999999994 or some long decimal number. I use console.log to check the $price and $qty. Both of them are in the correct format ex..299.99 and 6 quantity.I have no idea what happen. I would appreciate it if someone can help me about it. Here is my Jquery code. $(".price").each(function(index, price){ $price=$(this); //get the product id and the price shown on the page var id=$price.closest('tr').attr('id'); var indiPrice=$($price).html(); //take off $ indiPrice=indiPrice.substring(1) //make sure it is number format var aindiPrice=Number(indiPrice); //push into the array productIdPrice[id]=(aindiPrice); var url=update.php $.getJSON( url, {productId:tableId, //tableId is from the other jquery code which refers to qty:qty}, productId function(responseProduct){ $.each(responseProduct, function(productIndex, Qty){ //loop the return data if(productIdPrice[productIndex]){ //get the price from the previous array we create X Qty newSub=productIdPrice[productIndex]*Number(Qty); //productIdPrice[productIndex] are the price like 199.99 or 99.99 // Qty are Quantity like 9 or 10 or 3 sum+=newSub; newSub.toFixed(2); //try to solve the problem with toFixed but didn't work console.log("id: "+productIdPrice[productIndex]) console.log("Qty: "+Qty); console.log(newSub); **//newSub sometime become XXXX.96999999994** }; Thanks again!

  • javascript innerHTML without childNodes?

    - by John Doe
    hi all im having a firefox issue where i dont see the wood for the trees using ajax i get html source from a php script this html code contains a tag and within the tbody some more tr/td's now i want to append this tbody plaincode to an existing table. but there is one more condition: the table is part of a form and thus contains checkboxe's and drop down's. if i would use table.innerHTML += content; firefox reloads the table and reset's all elements within it which isnt very userfriendly as id like to have what i have is this // content equals transport.responseText from ajax request function appendToTable(content){ var wrapper = document.createElement('table'); wrapper.innerHTML = content; wrapper.setAttribute('id', 'wrappid'); wrapper.style.display = 'none'; document.body.appendChild(wrapper); // get the parsed element - well it should be wrapper = document.getElementById('wrappid'); // the destination table table = document.getElementById('tableid'); // firebug prints a table element - seems right console.log(wrapper); // firebug prints the content ive inserted - seems right console.log(wrapper.innerHTML); var i = 0; // childNodes is iterated 2 times, both are textnode's // the second one seems to be a simple '\n' for(i=0;i<wrapper.childNodes.length;i++){ // firebug prints 'undefined' - wth!?? console.log(wrapper.childNodes[i].innerHTML); // firebug prints a textnode element - <TextNode textContent=" "> console.log(wrapper.childNodes[i]); table.appendChild(wrapper.childNodes[i]); } // WEIRD: firebug has no problems showing the 'wrappid' table and its contents in the html view - which seems there are the elements i want and not textelements } either this is so trivial that i dont see the problem OR its a corner case and i hope someone here has that much of expirience to give an advice on this - anyone can imagine why i get textnodes and not the finally parsed dom elements i expect? btw: btw i cant give a full example cause i cant write a smaller non working piece of code its one of those bugs that occure in the wild and not in my testset thx all

  • Where to open sessions in a Spring/Hibernate stack?

    - by CaptainAwesomePants
    I'm trying to figure out a good design for a Spring/Hibernate app. When creating such an app, it appears like there are a handful of major decisions. The first major decision seems to be where to put the session/transaction boundary. It seems like I have 3 major choices: as a filter before controllers are even invoked, immediately below the controllers at the service call level, and stuffed way below the business level in repository calls. It seems to me like the right call is the middle path, but I'm not sure. I don't want my transactions open too long, but at the same time, I don't want to constantly worry about detached objects and lazy loading in the business logic. Still, there are some downsides. For instance, it makes it hard for the business logic to make a remote call without holding up a transaction for a few seconds. I wonder if there's a better way?

  • Logging exceptions to database in NServiceBus

    - by IGoor
    If an exception occurs in my MessageHandler I want to write the exception details to my database. How do I do this? Obviously, I cant just catch the exception, write to database, and rethrow it since NSB rollbacks all changes. (IsTransactional is set to true) I tried adding logging functionality in a seperate handler, which I caledl using SendLocal if an exception occured, but this does not work: public void Handle(MessageItem message) { try { DoWork(); } catch(Exception exc) { Bus.SendLocal(new ExceptionMessage(exc.Message)); throw; } } I also tried using Log4Net with a custom appender, but this also rolled back. Configure.With() .Log4Net<DatabaseAppender>(a => a.Log = "Log") appender: public class DatabaseAppender : log4net.Appender.AppenderSkeleton { public string Log { get; set; } protected override void Append(log4net.Core.LoggingEvent loggingEvent) { if (loggingEvent.ExceptionObject != null) WriteToDatabase(loggingEvent.ExceptionObject); } } Is there anyway to log unhandled exceptions in the messagehandler when IsTransactional is true? Thanks in advance.

  • Git graph with ref logs

    - by Francisco Garcia
    I am trying to improve my custom git log format string. I have almost everything I want except the ref names. I can already get a log similar to what I want: > git log --all --source --pretty=oneline --graph * b7c7ad3855b54e94ad7ac03f2d2e5b96d6e5ac1d refs/heads/b1 na | * 695e1482622a79230fa1d83afb8d70e86847334a refs/heads/master Merge branch 'b1' | |\ | |/ |/| * | ec21f370f82096c0208f43b390da234d92e8c74a refs/heads/b1 beta * | c6bc1f55ab3b1bd568493a5de4298dfcb4f66d8d refs/heads/b1 alfa * | 762dd868ae87753afc1cbf9803744c76f9a9e121 refs/heads/b1 tango | * 57fb27bff06ee9bb569f93ba815e9dcd69521c13 refs/heads/master little last post commit |/ | * 8d613d09b43152a7263b6e02d47ec8a4304f54be refs/heads/b3 the other commit | * e1f32b7cb86633351df06e37c2c58ef3f9fafc40 refs/heads/b3 something |/ | * 01b5c6728cf25dd576733211ce75dd3ecc29c7ba refs/heads/b2 this time a I am fighting to get a customized output with my own format string like this: > git log --pretty=format:'%h - %gD %s' --source -g b7c7ad3 - HEAD@{0} na ec21f37 - HEAD@{1} beta 01b5c67 - HEAD@{2} this time a 01b5c67 - HEAD@{3} this time a 695e148 - HEAD@{4} Merge branch 'b1' 57fb27b - HEAD@{5} little last post commit My main problem is that I cannot get the ref names I want. I assume it is one of the %g? format strings, but none of them seem to give me the full ref name. Another problem is that the %g? format strings are empty unless I walk the reflogs (-g). However git refuses to combine --graph with -g How can reproduce the first sample with a format string which I can further customize?

  • Javascript callback with AJAX + jQuery

    - by Fred
    Hey! I have this jQuery code (function () { function load_page (pagename) { $.ajax({ url: "/backend/index.php/frontend/pull_page/", type: "POST", data: {page: pagename}, success: function (json) { var parsed = $.parseJSON(json); console.log(parsed); return parsed; }, error: function (error) { $('#content').html('Sorry, there was an error: <br>' + error); return false; } }); } ... var json = load_page(page); console.log(json); if (json == false) { $('body').fadeIn(); } else { document.title = json.pagename + ' | The Other Half | freddum.com'; $("#content").html(json.content); $('#header-navigation-ul a:Contains('+page+')').addClass('nav-selected'); $('body').fadeIn(); } })(); and, guessed it, it doesn't work. The AJAX fires fine, the server returns valid JSON but the console.log(json); returns undefined and the js crashes when it gets to json.pagename. The first console.log(parsed) also returns good data so it's just a problem with the return (I think). I knew I was clutching at straws and would be extremely if this worked, but it doesn't. To be honest, I don't know how to program callback functions for this situation. Any help is greatly appreciated!

  • How to replace pairs of strings in two files to identical IDs?

    - by Péter Török
    Sorry if the title is not very intelligible, I couldn't come up with anything better. Hopefully my explanation is clear enough: I have a pair of rather large log files with very similar content, except that some strings are different between the two. A couple of examples: UnifiedClassLoader3@19518cc | UnifiedClassLoader3@d0357a JBossRMIClassLoader@13c2d7f | JBossRMIClassLoader@191777e That is, wherever the first file contains UnifiedClassLoader3@19518cc, the second contains UnifiedClassLoader3@d0357a, and so on. [Update] There are about 40 distinct pairs of such identifiers.[/Update] I want to replace these with identical IDs so that I can spot the really important differences between the two files. I.e. I want to replace all occurrences of both UnifiedClassLoader3@19518cc in file1 and UnifiedClassLoader3@d0357a in file2 with UnifiedClassLoader3@1; all occurrences of both JBossRMIClassLoader@13c2d7f in file1 and JBossRMIClassLoader@191777e in file2 with JBossRMIClassLoader@2 etc. Using the Cygwin shell, so far I managed to list all different identifiers occurring in one of the files with grep -o -e 'ClassLoader[0-9]*@[0-9a-f][0-9a-f]*' file1.log | sort | uniq However, now the original order is lost, so I don't know which is the pair of which ID in the other file. With grep -n I can get the line number, so the sort would preserve the order of appearance, but then I can't weed out the duplicate occurrences. Unfortunately grep can not print only the first match of a pattern. I figured I could save the list of identifiers produced by the above command into a file, then iterate over the patterns in the file with grep -n | head -n 1, concatenate the results and sort them again. The result would be something like 2 ClassLoader3@19518cc 137 ClassLoader@13c2d7f 563 ClassLoader3@1267649 ... Then I could (either manually or with sed itself) massage this into a sed command like sed -e 's/ClassLoader3@19518cc/ClassLoader3@2/g' -e 's/ClassLoader@13c2d7f/ClassLoader@137/g' -e 's/ClassLoader3@1267649/ClassLoader3@563/g' file1.log > file1_processed.log and similarly for file2. However, before I start, I would like to verify that my plan is the simplest possible working solution to this. Is there any flaw in this approach? Is there a simpler way?

  • zend session exception on zend_session::start with forms

    Hi I'm having issues with trying to use Zend_Form_SubForm and sessions. My controller is in essance acting a wizard showing different subforms depending on the stage of the wizard. Using the example I am planning on storing the forms in a session namespace. My controller looks like this. include 'mylib/Form/addTaskWizardForm.php'; class AddtaskController extends Zend_Controller_Action{ private $config = null; private $log = null; private $subFormSession = null; /** * This function is called and initialises the global variables to this object * which is the configuration details and the logger to write to the log file. */ public function init(){ $this->config = Zend_Registry::getInstance()->get('config'); $this->log = Zend_Registry::getInstance()->get('log'); //set layout $this->_helper->layout->setLayout('no-sidemenus'); //we need to get the subforms and $wizardForms = new addTaskWizardForm(); $this->subFormSession = new Zend_Session_Namespace('addTaskWizardForms'); if(!isset($this->subFormSession->subforms)){ $this->subFormSession->subforms = $wizardForms; } } /** * The Landing page controller for the site. */ public function indexAction(){ $form = $this->subFormSession->subforms->getSubForm('start'); $this->view->form = $form; } However this is causing the application session to crash out with Uncaught exception 'Zend_Session_Exception' with message 'Zend_Session::start() Any idea why this is having issues with the Zend Session?? thanks.

  • innodb lock wait timeout

    - by shantanuo
    As per the documentation link given below: When a lock wait timeout occurs, the current statement is not executed. The current transaction is not rolled back. (Until MySQL 5.0.13 InnoDB rolled back the entire transaction if a lock wait timeout happened. You can restore this behavior by starting the server with the --innodb_rollback_on_timeout option, available as of MySQL 5.0.32. http://dev.mysql.com/doc/refman/5.0/en/innodb-parameters.html#sysvar_innodb_lock_wait_timeout Does it mean that when a lock wait timeout occurs, it compromises the transactional integrity? "roollback on timeout" was the default behaviour till 5.0.13 and I guess that was the correct way to handle such situations. Does anyone think that this should be the default behaviour and the user should not be asked to add a parameter for a functionality that is taken for granted?

  • How do I bind arrays to columns in a WPF datagrid

    - by user1432917
    I have a Log object that contains a list of Curve objects. Each curve has a Name property and an array of doubles. I want the Name to be in the column header and the data below it. I have a user control with a datagid. Here is the XAML; <UserControl x:Class="WellLab.UI.LogViewer" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" mc:Ignorable="d" d:DesignHeight="500" d:DesignWidth="500"> <Grid> <StackPanel Height="Auto" HorizontalAlignment="Stretch" Margin="0" Name="stackPanel1" VerticalAlignment="Stretch" Width="Auto"> <ToolBarTray Height="26" Name="toolBarTray1" Width="Auto" /> <ScrollViewer Height="Auto" Name="scrollViewer1" Width="Auto" HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Visible" CanContentScroll="True" Background="#E6ABA4A4"> <DataGrid AutoGenerateColumns="True" Height="Auto" Name="logDataGrid" Width="Auto" ItemsSource="{Binding}" HorizontalAlignment="Left"> </DataGrid> </ScrollViewer> </StackPanel> </Grid> In the code behind I have figured out how to create columns and name them, but I have not figured out how to bind the data. public partial class LogViewer { public LogViewer(Log log) { InitializeComponent(); foreach (var curve in log.Curves) { var data = curve.GetData(); var col = new DataGridTextColumn { Header = curve.Name }; logDataGrid.Columns.Add(col); } } } I wont even show the code I tried to use to bind the array "data", since nothing even came close. I am sure I am missing something simple, but after hours of searching the web, I have to come begging for an answer.

  • Starting an Intent to Launch an app to Background in Android

    - by Tista
    Hi all, I'm using Wikitude API 1.1 as an AR viewer in my application. The problem with Wikitude, if I haven't launched the actual Wikitude application since the phone's bootup, I will get a NullPointerException everytime I start my own application. So I figure if I can start my app first and them check if Wikitude is installed and or running. If it's not installed, go to market n download. If it's not running, then we should run it straight to background so that my app doesn't loose its focus. // Workaround for Wikitude this.WIKITUDE_PACKAGE_NAME = "com.wikitude"; PackageManager pacMan = Poligamy.this.getPackageManager(); try { PackageInfo pacInfo = pacMan.getPackageInfo(this.WIKITUDE_PACKAGE_NAME, pacMan.GET_SERVICES); Log.i("CheckWKTD", "Wikitude is Installed"); ActivityManager aMan = (ActivityManager) this.getSystemService(ACTIVITY_SERVICE); List<RunningAppProcessInfo> runningApps = aMan.getRunningAppProcesses(); int numberOfApps = runningApps.size(); for(int i=0; i<numberOfApps; i++) { if(runningApps.get(i).processName.equals(this.WIKITUDE_PACKAGE_NAME)) { this.WIKITUDE_RUNNING = 1; Log.i("CheckWKTD", "Wikitude is Running"); } } if(this.WIKITUDE_RUNNING == 0) { Log.i("CheckWKTD", "Wikitude is NOT Running"); /*final Intent wIntent = new Intent(Intent.ACTION_MAIN, null); wIntent.addCategory(Intent.CATEGORY_LAUNCHER); final ComponentName cn = new ComponentName("com.wikitude", "com.mobilizy.wikitudepremium.initial.Splash"); wIntent.setComponent(cn); wIntent.setFlags(Intent.FLAG_ACTIVITY_NO_USER_ACTION); startActivityIfNeeded(wIntent, 0);*/ } } catch (NameNotFoundException e) { // TODO Auto-generated catch block Log.i("CheckWKTD", "Wikitude is NOT Installed"); e.printStackTrace(); //finish(); } The part I block commented is the intent to start Wikitude. But I always failed in restricting Wikitude to background. Any help? Thanks before. Best, Tista

  • Get the ID of a Child in a cascade="all" relationship, while adding it to a collection, in Hibernate

    - by Marco
    Hi, i have two Entities, "Parent" and "Child", that are linked through a bidirectional one-to-many relationship with the cascade attribute set to "all". When adding a Child object to the Parent children collection using the code below, i can't get the ID of the persisted child until i commit the transaction: Parent p = (Parent) session.load(Parent.class, pid); Child c = new Child(); p.addChild(c); // "c" hasn't an ID (is always zero) However, when i persist a child entity by explicitly calling the session.save() method, the ID is created and set immediately, even if the transaction hasn't been committed: Child c = new Child(); session.save(c); // "c" has an ID Is there a way to get the ID of the child entity immediately without calling the session.save() method? Thanks
