EMF ecore and xsd out of sync, how to resolve ?

- by SeB

Hi there, My application is using a model base on an xsd that have been converted to an ecore before generation of the java classes. One of my team member modified the .ecore metamodel in a previous version ,one attribute that used to be generated. He modified the attribute name but not the Extended MetaData specifying the element name used for xml persistance. <eStructuralFeatures xsi:type="ecore:EReference" name="javaDocsAndUserApi" upperBound="-1" eType="#//JavaDocsAndUserApi" containment="true" resolveProxies="false"> <eAnnotations source="http:///org/eclipse/emf/ecore/util/ExtendedMetaData"> <details key="kind" value="element"/> <details key="name" value="docsAndUserApi"/> </eAnnotations> </eStructuralFeatures> so we have an attribute name which is javaDocsAndUserApi and the persisted element named docsAndUserApi, and of course if I create change the attribute in the xsd to be named javaDocsAndUserApi, the ecore transformation will generate a metadata name javaDocsAndUserApi as well, which will break compatibility with previously persisted models. I have looked at xsd authoring guide to find an ecore:som_attribute that would allow me to specify which key to use in the xsd to force the metadata to be named docsAndUserApi during the xsd to ecore transformation but did not find anything. Does anybody have an idea to help me? Thank you.

Aligning music notes using String matching algorithms or Dynamic Programming

- by Dolphin

Hi I need to compare 2 sets of musical pieces (i.e. a playing-taken in MIDI format-note details extracted and saved in a database table, against sheet music-taken into XML format). When evaluating playing against sheet music (i.e.note details-pitch, duration, rhythm), note alignment needs to be done - to identify missed/extra/incorrect/swapped notes that from the reference (sheet music) notes. I have like 1800-2500 notes in one piece approx (can even be more-with polyphonic, right now I'm doing for monophonic). So will I have to have all these into an array? Will it be memory overloading or stack overflow? There are string matching algorithms like KMP, Boyce-Moore. But note alignment can also be done through Dynamic Programming. How can I use Dynamic Programming to approach this? What are the available algorithms? Is it about approximate string matching? Which approach is much productive? String matching algos like Boyce-Moore, or dynamic programming? How can I assess which is more effective? Greatly appreciate any insight or suggestions Thanks in advance

making clean page via page.tpl.php

- by user360051

I have a Drupal module creating a page via hook_menu(). I am trying to make it so the page has no extraneous html output, only what I want. You can view the page here, http://www.thomashansen.me/chat/thomas. If you look at the source, you can see a strange script tag at the end. My page-chat.tpl.php looks like this, <?php // $Id$ ?> <!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="<?php print $language->language ?>" lang="<?php print $language->language ?>" dir="<?php print $language->dir ?>"> <head> </head> <body> <?php print $content; ?> </body> </html> Where is that script tag coming from? and how do I get rid of it? If you need more information just ask.

Is context:annotation-config an alternative to @AutoWired?

- by Antacid

Is it correct that I can put context:annotation-config in my XML config and it will automatically inject the bean class without needing any annotations? So instead of using these annotation types: public class Mailman { private String name; @Autowired private Parcel Parcel; public Mailman(String name) { this.name = name; } @Autowired public void setParcel(Parcel Parcel) { this.Parcel = Parcel; } @Autowired public void directionsToParcel(Parcel Parcel) { this.Parcel = Parcel; } } I would just need to write this: <beans ... > <bean id="mailMan" class="MailMan"> <constructor-arg value="John Doe"/> </bean> <bean id="parcel" class="Parcel" /> <context:annotation-config /> </beans> and then my MailMan class would look a lot simpler without the need for annotations: public class Mailman { private String name; private Parcel Parcel; public Mailman(String name) { this.name = name; } }

Why doesn't setting clearTaskOnLaunch="true" cause OnCreate to be called?

- by cbrauer

My application works fine, once it is initialized in the OnCreate method of my View class. However, when I open my app after the Droid phone has been sitting idle all night, the OnCreate method is not being called. I use the OnCreate to initialize data, and that in turn initializes the GUI. The GUI clearly shows that OnCreate was not called. I tried setting clearTaskOnLaunch="true" in my Manifest. My Manifest is: <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.hedgetools.trin" android:versionCode="2" android:versionName="1.02"> <application android:icon="@drawable/icon" android:label="@string/app_name" android:clearTaskOnLaunch="true"> <activity android:name=".Trin" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> <uses-sdk android:minSdkVersion="6" /> <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> </manifest> This did not help. My OnCreate method is not being call after the Droid phone sits idle all night. Why doesn’t clearTaskOnLaunch cause OnCreate to be called? Any help or suggestions will be greatly appreciated.

Adding an Array inside an array in a PHP function

- by bateman_ap

I have created a function in PHP that calls a webservice and parses through the result, assinging values to variables and returning them all as an Array. This all works perfectly, however I have come across a need to have an "array within my array" I am assigning values as below: $productName = $product->Name; $productID = $product->ID; $productArray = array( 'productName' => "$productName", 'productID' => "$productID" ); return $productArray; However I now have a piece of data that comes back with multiple results so I need to have a additional array to store these, I am getting the values from the returned XML using a foreach loop, however I want to be able to add them to the array with a name so I can reference them in the returned data, this is where I have a problem... $bestForLists = $product->BestFors; foreach( $bestForLists as $bestForList ) { $productBestFors = $bestForList->BestFor; foreach( $productBestFors as $productBestFor ) { $productBestForName = $productBestFor->Name; $productBestForID = $productBestFor->ID; } } I tried creating an array for these using the below code: $bestForArray[] = (array( "productBestForID" => "$productBestForID", "productBestForName" => "$productBestForName" )); And then at the end merging these together: $productArray= array_merge($productArray,$bestForArray); If I print out the returned value I get: Array ( [productName] => Test Product [productID] => 14128 [0] => Array ( [productBestForID] => 56647 [productBestForName] => Lighting ) [1] => Array ( [productBestForID] => 56648 [productBestForName] => Sound ) ) I would like to give the internal Array a name so I can reference it in my code, or is there a better way of doing this, at the moment I am using the following in my PHP page to get values: $productName = $functionReturnedValues['productName']; I would like to use the following to access the array I could then loop through: $bestForArray = $functionReturnedValues['bestForArray']; Hope someone can help

Why is my searchable activity's Intent.getAction() null?

- by originalbryan

I've followed the SearchManager documentation yet am still having trouble making one of my app's activities searchable. From my activity, the SearchDialog appears, I enter a query, hit search, my activity reopens, then I see this in the log: D/SearchDialog( 584): launching Intent { act=android.intent.action.SEARCH flg=0x10000000 cmp=com.clinkybot.geodroid2/.views.Waypoints (has extras) } I/SearchDialog( 584): Starting (as ourselves) #Intent;action=android.intent.action.SEARCH;launchFlags=0x10000000;component=com.clinkybot.geodroid2/.views.Waypoints;S.user_query=sdaf;S.query=sdaf;end I/ActivityManager( 584): Starting activity: Intent { act=android.intent.action.SEARCH flg=0x10000000 cmp=com.clinkybot.geodroid2/.views.Waypoints (has extras) } D/WAYPOINTS( 1018): NI Intent { cmp=com.clinkybot.geodroid2/.views.Waypoints (has extras) } D/WAYPOINTS( 1018): NI null D/WAYPOINTS( 1018): NI false It appears to me that everything is fine up until the last three lines. The "NI" lines are getIntent().toString(), getIntent().getAction(), and getIntent().hasExtra(SearchManager.QUERY) respectively. ActivityManager appears to be starting my activity with the correct action. Then when my activity starts, it contains no action!? What am I doing wrong? The relevant portion of my manifest is: <activity android:name=".views.Waypoints" android:label="Waypoints" android:launchMode="singleTop"> <intent-filter> <action android:name="android.intent.action.SEARCH" /> <category android:name="android.intent.category.DEFAULT" /> </intent-filter> <meta-data android:name="android.app.searchable" android:resource="@xml/searchable" /> </activity>

What is the proper way to set my drawable directories to support the new Dell Streak without losing support for older devices?

- by emmby

This seems to be a widespread problem. I have the following drawable directories: drwxr-xr-x 18 mike staff 612 Feb 4 17:28 drawable/ drwxr-xr-x 51 mike staff 1734 Feb 4 17:32 drawable-nodpi/ drwxr-xr-x 44 mike staff 1496 Feb 4 17:30 drawable-normal-mdpi/ My xml drawable resources are in drawable. My resources intended for the large-mdpi (Dell Streak) and normal-hdpi (Droid, Nexus, Incredible, etc.) are all in drawable-nodpi. My resources for normal-mdpi (older phones like the G1) are in drawable-normal-mdpi. Unfortunately, the normal-hdpi phones like the Droid are pulling their resources from drawable-normal-mdpi instead of from drawable-nodpi. This is likely because of the rules in How Android Finds the Best-matching Resource. So the question is, how do I provide support for large-mdpi devices like the Streak along with normal-hdpi devices like the Droid, as well as normal-mdpi devices like the G1? The simplest solution would probably be to make two copies of my large resources, one in normal-hdpi for the droid and one in large-mdpi for the streak, but i'd like to avoid duplicating all of these resources. Update Per Mayra's suggestion, I could make an alias for every resource. However, there are a lot of resources I'd have to make aliases for, which would make maintenance a nightmare going forward, so I'm hoping for another solution.

Hibernate not saving foreign key, but with junit it's ok

- by Leonardo

Hi All, I have this strange problem. In a J2ee webapp with spring, smartgwt and hibernate, it happens that I have a class A wich has a set of class B, both of them mapped to table A and table B. I wrote a simple test case for testing the service manager which is supposed to do insert, update, delete and everything work as expected especially during insert. In the end I have one record in A and records in B with foreign key to A. But when I try to call the service from the web app, the entity in B are saved without a foreign key reference. I am sure that the service is the same. One thing I noticed is that enabling hibernate logging, seems that when the service is called from the application, one more update is made: insert A insert B update A update B update B (foreign key only) update A <--- ??? update B <--- ??? Instead, when junit test case is run, the update is as follows: insert A insert B update A update B update B (foreign key only) I suppose the latest update is what is causing the erroe, maybe it is overwriting values. Considering that the app is using spring, with the well known mechanism of DAO + Manager, where can I investigate to solve this issue ? Someone told me that the session is not closed, so hibernate would do one more update before release the objects by itself. I am pretty sure that all the configuration hbm, xml, and the rest are fine...but I maybe wrong. thanks

Why does Hibernate 2nd level cache only cache queries within a session?

- by Synesso

Using a named query in our application and with ehcache as the provider, it seems that the query results are tied to the session within the cache. Any attempt to access the value from the cache for a second time results in a LazyInitializationException We have set lazy = true for the following mapping because this object is also used by another part of the system which does not require the reference... and we want to keep it lean. <class name="domain.ReferenceAdPoint" table="ad_point" mutable="false" lazy="false"> <cache usage="read-only"/> <id name="code" type="long" column="ad_point_id"> <generator class="assigned" /> </id> <property name="name" column="ad_point_description" type="string"/> <set name="synonyms" table="ad_point_synonym" cascade="all-delete-orphan" lazy="true"> <cache usage="read-only"/> <key column="ad_point_id" /> <element type="string" column="synonym_description" /> </set> </class> <query name="find.adpoints.by.heading">from ReferenceAdPoint adpoint left outer join fetch adpoint.synonyms where adpoint.adPointField.headingCode = ?</query> Here's a snippet from our hibernate.cfg.xml <property name="hibernate.cache.provider_class">net.sf.ehcache.hibernate.SingletonEhCacheProvider</property> <property name="hibernate.cache.use_query_cache">true</property> It doesn't seem to make sense that the cache would be constrained to the session. Why are the cached queries not usable outside of the (relatively short-lived) sessions?

How to inherit the current path when invoking Maven's exec-maven-plugin?

- by wishihadabettername

I have an <exec-maven-plugin> which calls an external command (in this case, svnversion). The command is in the path for the current user. However, when a separate shell is spawned by the plugin, the path is not initialized. I don't want to hardcode or define a variable for each external command (there would be too much to maintain, especially that there are both Windows and *nix users). My pom.xml contains the following: <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>exec-maven-plugin</artifactId> <version>1.1</version> <executions> <execution> <id>svnversion-exec</id> <phase>process-resources</phase> <goals> <goal>exec</goal> </goals> <configuration> <executable>svnversion</executable> <arguments> <argument><![CDATA[ >version.txt ]]></argument> </arguments> </configuration> </execution> </executions> </plugin> Currently I get the following output: [INFO] [exec:exec {execution: svnversion-exec}] 'svnversion' is not recognized as an internal or external command, operable program or batch file. [ERROR] BUILD ERROR: Result of cmd.exe /X /C "svnversion >version.txt" execution is: '1'. Thank you!

How to start animation when I'm pressing on item of ListView?

- by Ares

I want to implement next functional: When I'm tapping on ListView's item, it's turning into red color. If I release it has to reverse color back. I made transition drawable and set it as item's background. I tried to implement SimpleGestureListener and started animation on onDown and reversed it on onSingleTapUp events, but it doesn't give me any results (works fine, but items don't turn into red). If I return super.onDown (not true), the onLongPress raise every time(even I manage to release it). @Override public boolean onDown(MotionEvent e) { if(_currentRow.getTag()!=null) if(_currentRow.getTag().toString().equals("anim")) _currentRow.setBackgroundDrawable(context.getResources() .getDrawable(R.xml.listviewitem_yellow_red)); _drawable = (TransitionDrawable) _currentRow.getBackground(); _drawable.startTransition(500); return true; //super.onDown(e); // IF I UNCOMMENT IT TURNS INTO RED, BUT TRIGGERED onLongClick event!!! } @Override public boolean onSingleTapUp(MotionEvent e) { if(_drawable!=null){ _drawable.reverseTransition(500); } return super.onSingleTapUp(e); } @Override public void onLongPress(MotionEvent e) { if(getLongClickListener()!=null) getLongClickListener().onLongClick(_currentRow, _object); super.onLongPress(e); } If someone knows how to solve this problem, please help me.

Cross-domain data access in JavaScript

- by vit

We have an ASP.Net application hosted on our network and exposed to a specific client. This client wants to be able to import data from their own server into our application. The data is retrieved with an HTTP request and is CSV formatted. The problem is that they do not want to expose their server to our network and are requesting the import to be done on the client side (all clients are from the same network as their server). So, what needs to be done is: They request an import page from our server The client script on the page issues a request to their server to get CSV formatted data The data is sent back to our application This is not a challenge when both servers are on the same domain: a simple hidden iframe or something similar will do the trick, but here what I'm getting is a cross-domain "access denied" error. They also refuse to change the data format to return JSON or XML formatted data. What I tried and learned so far is: Hidden iframe -- "access denied" XMLHttpRequest -- behaviour depends on the browser security settings: may work, may work while nagging a user with security warnings, or may not work at all Dynamic script tags -- would have worked if they could have returned data in JSON format IE client data binding -- the same "access denied" error Is there anything else I can try before giving up and saying that it will not be possible without exposing their server to our application, changing their data format or changing their browser security settings? (DNS trick is not an option, by the way).

ASP.NET 2.0 + Firefox/Safari - UI Issues?

- by Tejaswi Yerukalapudi

I'm developing on a system that was originally developed five years ago. I don't have access to the complete source code of the system, but it is completely driven by XML and runs on ASP.NET 2.0. This was originally written for IE6, but since Microsoft has officially decided to dump it, we moved to IE7. Some javascript is added on the client side, but nothing that changes the UI has been done. (We had to integrate a credit card reader into the system) This code is accessed primarily on tablet PCs running windows, but I'd like to persuade my company to use the iPad. [The tablet somehow costs around 3k$. I think selling a 3000$ device to a client when you have the iPad for 500$ is ridiculous.] Now, my problem is if we open it in any other browser (Tested it on safari / firefox), the UI is completely messed up with elements completely out of place. Doesn't ASP.NET generate HTML that runs on any browser? My second question is if there are any credit card readers available in the market that integrate with the iPad. I don't really care about the software part as it's taken care by our company, I just need it to read the card details and post it to the server. Thanks, Teja.

How do you move an admin menu item in Magento

I currently have an extension that I created and it currently sits inside of its own top level menu. I would like to move it so that the item would appear inside of the Customers menu. Does anyone know how to do this? It looks like this is handled inside the extensions config.xml file. The code that I have for it right now is as follows: <menu> <testimonials module="testimonials"> <title>Testimonials</title> <sort_order>71</sort_order> <children> <items module="testimonials"> <title>Manage Items</title> <sort_order>0</sort_order> <action>testimonials/adminhtml_testimonials</action> </items> </children> </testimonials> </menu> I tried changing the title element to Customers and it just created a duplicate Customers menu. Does anyone have any ideas? Thanks Josh Pennington

How do you deserialize a collection with child collections?

- by Stuart Helwig

I have a collection of custom entity objects one property of which is an ArrayList of byte arrays. The custom entity is serializable and the collection property is marked with the following attributes: [XmlArray("Images"), XmlArrayItem("Image",typeof(byte[]))] So I serialize a collection of these custom entities and pass them to a web service, as a string. The web service receives the string and byte array in tact, The following code then attempts to deserialize the collection - back into custom entities for processing... XmlSerializer ser = new XmlSerializer(typeof(List<myCustomEntity>)); StringReader reader = new StringReader(xmlStringPassedToWS); List<myCustomEntity> entities = (List<myCustomEntity>)ser.Deserialize(reader); foreach (myCustomEntity e in entities) { // ...do some stuff... foreach (myChildCollection c in entities.ChildCollection { // .. do some more stuff.... } } I've checked the XML resulting from the initial serialization and it does contain byte array - the child collection, as does the StringReader built above. After the deserialization process, the resulting collection of custom entites is fine, except that each object in the collection does not contain any items in its child collection. (i.e. it doesn't get to "...do some more stuff..." above. Can someone please explain what I am doing wrong? Is it possible to serialize ArrayLists within a generic collection of custom entities?

Programatically enable/disable menuBar buttons in Flex 4

I have the following XML in my Flex4 (AIR) project that defines the start of my menu interface: <mx:MenuBar x="0" y="0" width="100%" id="myMenuBar" labelField="@label" itemClick="menuChange(event)"> <mx:dataProvider> <s:XMLListCollection> <fx:XMLList xmlns=""> <menu label="File"> <item label="New"/> <item label="Load"/> <item label="Save" enabled="false"/> </menu> <menu label="Help"> <item label="About"/> </menu> </fx:XMLList> </s:XMLListCollection> </mx:dataProvider> </mx:MenuBar> I am trying to find the syntax that will let me set the save button to enabled=true after a file has been loaded by clicking "Load", however I can't figure out the syntax, can someone make a suggestion please. Currently the way that button clicks are detected is by a Switch/Case testing the String result of the MenuEvent event.item.@label. Maybe this isn't the best way?

MySQL Server version: 5.1.44 MySQL charset: UTF-8 Unicode (utf8) I create a new database name: utf8test collation: utf8_general_ci MySQL connection collation: utf8_general_ci My SQL looks like this: SET SQL_MODE="NO_AUTO_VALUE_ON_ZERO"; CREATE TABLE IF NOT EXISTS `test_table` ( `test_id` int(11) NOT NULL, `test_text` text NOT NULL, PRIMARY KEY (`test_id`) ) ENGINE=MyISAM DEFAULT CHARSET=utf8; INSERT INTO `test_table` (`test_id`, `test_text`) VALUES (1, 'hééélo'), (2, 'wööörld'); My PHP / HTML: <?php $db_conn = mysql_connect("localhost", "root", "") or die("Can't connect to db"); mysql_select_db("utf8test", $db_conn) or die("Can't select db"); // $result = mysql_query("set names 'utf8'"); // this works... why?? $query = "SELECT * FROM test_table"; $result = mysql_query($query); $output = ""; while($row = mysql_fetch_assoc($result)) { $output .= "id: " . $row['test_id'] . " - text: " . $row['test_text'] . "<br />"; } ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html lang="it" xmlns="http://www.w3.org/1999/xhtml" xml:lang="it"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>UTF-8 test</title> </head> <body> <?php echo $output; ?> </body> </html>

Hibernate collection multiple types

- by CaptainAwesomePants

I have a class Player that contains a list of Accessory objects. There are two kinds of Accessories. SocketedAccessories have a list of SocketJewels, and MagicAccessories have a list of MagicEnchantments. At the database level, there is a players table that represents the player, and an accessories table that contains a list of accessories. Accessories have a type field that indicates whether they are socketed or magical, and the columns that are only used by one type are just left blank by entries of the other type. There are socket_jewels and magic_enchantments tables, representing the socket jewels or the magic enchantments on each accessory. I am trying to figure out the correct way to map this with Hibernate. One way would be for the player to have two lists of accessories, one for SocketedAccessories and one for MagicAccessories. That seems undesirable, though. What I want is a way to specify that player should have a field List<Accessory> accessories that contains both types of thing. Is there a way to tell Hibernate, in either hbm.xml or annotations, to do this?
