• Actually XSLT Lookup (Store variables during loop and use in it another template)

  - by krisvandenbergh

  Is there a way to store a variable/param during a for-each loop in a sort of array, and use it in another template, namely <xsl:template match="Foundation.Core.Classifier.feature">. All the classname values that appear during the for-each should be stored. How would you implement that in XSLT? Here's my current code. <xsl:for-each select="Foundation.Core.Class"> <xsl:for-each select="Foundation.Core.ModelElement.name"> <xsl:param name="classname"> <xsl:value-of select="Foundation.Core.ModelElement.name"/> </xsl:param> </xsl:for-each> <xsl:apply-templates select="Foundation.Core.Classifier.feature" /> </xsl:for-each> Here's the template in which the classname parameters should be used. <xsl:template match="Foundation.Core.Classifier.feature"> <xsl:for-each select="Foundation.Core.Attribute"> <owl:DatatypeProperty rdf:ID="{Foundation.Core.ModelElement.name}"> <rdfs:domain rdf:resource="$classname" /> </owl:DatatypeProperty> </xsl:for-each> </xsl:template> The input file can be found at http://krisvandenbergh.be/uml_pricing.xml

• can someone help me with why my OnClickListener won't work? Android

  - by clayton33

  Is there something simple i might be missing? The "kruis" picture shows up on my ImageButton, so i'm pretty sure my main.xml is good, but when i click on the ImageButton, i get no Toast and testView does not change... been struggling for a few hours on this now, not sure what i'm doing wrong! package com.matchit; import android.app.Activity; import android.os.Bundle; import android.view.View; import android.view.View.OnClickListener; import android.widget.ImageButton; import android.widget.TextView; import android.widget.Toast; public class matchit extends Activity { OnClickListener cardListener; TextView testView; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); testView = (TextView)findViewById(R.id.test); ImageButton b1 = (ImageButton)findViewById(R.id.card1); b1.setImageResource(R.drawable.kruis); b1.setOnClickListener(cardListener); cardListener = new OnClickListener(){ @Override public void onClick(View v) { testView.setText("its working"); Toast.makeText(getApplicationContext(), "its working", Toast.LENGTH_LONG).show(); } }; } }

• IPad SQLite Push and Pull Data from external MS SQL Server DB

  - by MattyD

  This carries on from my previous post (http://stackoverflow.com/questions/4182664/ipad-app-pull-and-push-relational-data). My plan is that when the ipad application starts I am going to pull data (config data i.e. Departments, Types etc etc relational data that is used across the system) from a webhosted MS SQL Server DB via a webservice and populate it into an SQL Lite DB on the IPad. Then when I load a listing I will pull the data over the line again via a webservice and populate it into the SQL Lite db on the ipad (than just run select commands to populate the listing). My questions are: 1. What is the most efficient way to transfer data across the line via the web? Everyone seems to do it a different way. My idea is that I will have a webService for each type of data pull (e.g. RetrieveContactListing) that will query the db and than convert that data into "something" to send across the line. My question really is what is the "something" that it should be converting into? 2. Everyone talks about odata services. Is this suited for applications where complex read and writes are needed? Ive created a simple iphone app before that talked to an sql server db (i just sent my own structured xml across the line) but now with this app the data calls are going to be a lot larger so efficiency is key.

• 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; } }

• Hibernate collection mapping challenge

• How to reference an embedded JCA resource adapater

  - by cg

  For our current J2EE project based on JBoss, we need to interface with a remote system using message driven beans and a JCA resource adapter provided as a RAR file by a third party. I would like to package and deploy the entire project as an EAR file to our JBoss server. Most notably, the RAR file should be embedded within the EAR file and not be deployed globally. All of this is working fine so far, but I'm not particularly happy with the way the RAR file is referenced. The jboss.xml packaged with the MDB for example, currently looks like this: <jboss> <enterprise-beans> <message-driven> <ejb-name>testBean1</ejb-name> <resource-adapter-name>test1.ear#thirdparty-1.0.rar</resource-adapter-name> </message-driven> </enterprise-beans> </jboss> While this is generally working fine, it will break when the EAR file is renamed to "test2.ear". Is there a way to reference the embedded RAR file without hard-coding the containing archive's name?

• JPA/Hibernate Parent/Child relationship

  - by NubieJ

  Hi I am quite new to JPA/Hibernate (Java in general) so my question is as follows (note, I have searched far and wide and have not come across an answer to this): I have two entities: Parent and Child (naming changed). Parent contains a list of Children and Children refers back to parent. e.g. @Entity public class Parent { @Id @Basic @GeneratedValue(strategy = GenerationType.IDENTITY) @Column(name = "PARENT_ID", insertable = false, updatable = false) private int id; /* ..... */ @OneToMany(cascade = { CascadeType.ALL }, fetch = FetchType.LAZY) @JoinColumn(name = "PARENT_ID", referencedColumnName = "PARENT_ID", nullable = true) private Set<child> children; /* ..... */ } @Entity public class Child { @Id @Basic @GeneratedValue(strategy = GenerationType.IDENTITY) @Column(name = "CHILD_ID", insertable = false, updatable = false) private int id; /* ..... */ @ManyToOne(cascade = { CascadeType.REFRESH }, fetch = FetchType.EAGER, optional = false) @JoinColumn(name = "PARENT_ID", referencedColumnName = "PARENT_ID") private Parent parent; /* ..... */ } I want to be able to do the following: Retrieve a Parent entity which would contain a list of all its children (List), however, when listing Parent (getting List, it of course should omit the children from the results, therefore setting FetchType.LAZY. Retrieve a Child entity which would contain an instance of the Parent entity. Using the code above (or similar) results in two exceptions: Retrieving Parent: A cycle is detected in the object graph. This will cause infinitely deep XML... Retrieving Child: org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role: xxxxxxxxxxx, no session or session was closed When retrieving the Parent entity, I am using a named query (i.e. calling it specifically) @NamedQuery(name = "Parent.findByParentId", query = "SELECT p FROM Parent AS p LEFT JOIN FETCH p.children where p.id = :id") Code to get Parent (i.e. service layer): public Parent findByParentId(int parentId) { Query query = em.createNamedQuery("Parent.findByParentId"); query.setParameter("id", parentId); return (Parent) query.getSingleResult(); } Why am I getting a LazyInitializationException event though the List property on the Parent entity is set as Lazy (when retrieving the Child entity)?

• Programmatic Text Wrapping in TextView

  - by Andrew

  I'm working on a custom widget for my application to replicate the look of a Preference button for layouts. The issue is the 'summary' text wont wrap when it hits the right wall of the view. One of the goals I'm trying to keep is that this widget is completely made from java with no xml attributes. here's what the widget looks like at the moment: http://dl.dropbox.com/u/56017670/Screenshot_2012-09-05-17-22-45.png notice that the middle two don't wrap the text but the text obviously runs right off the edge of the widget below is the code I'm using to create the text view. public void setSummary(String summary) { if (!TextUtils.isEmpty(summary)) { if (mSummaryView == null) { mSummaryView = new TextView(mContext); mSummaryView.setTextSize(14); mSummaryView.setTextColor(mContext.getResources().getColor( android.R.color.tertiary_text_dark)); addView(mSummaryView); } mSummaryView.setText(summary); mSummaryView.setVisibility(View.VISIBLE); } else { if (mSummaryView != null) { mSummaryView.setVisibility(View.GONE); } } mSummaryText = summary; } and here is the code I'm using to layout mSummaryView mSummaryView.layout( mPreferencePadding + mIconWidth, centerVertical + (mCombinedTextHeight / 2) - mSummaryHeight, width - mPreferencePadding, centerVertical + (mCombinedTextHeight / 2)); I've tried to add mSummaryView.setSingleLine(false); along with quite a few other tricks but they all ended in the same way.

• What is the performance impact of CSS's universal selector?

  - by Bungle

  I'm trying to find some simple client-side performance tweaks in a page that receives millions of monthly pageviews. One concern that I have is the use of the CSS universal selector (*). As an example, consider a very simple HTML document like the following: <!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>Example</title> <style type="text/css"> * { margin: 0; padding: 0; } </head> <body> <h1>This is a heading</h1> <p>This is a paragraph of text.</p> </body> </html> The universal selector will apply the above declaration to the body, h1 and p elements, since those are the only ones in the document. In general, would I see better performance from a rule such as: body, h1, p { margin: 0; padding: 0; } Or would this have exactly the same net effect? Essentially, what I'm asking is if these rules are effectively equivalent in this case, or if the universal selector has to perform more unnecessary work that I may not be aware of. I realize that the performance impact in this example may be very small, but I'm hoping to learn something that may lead to more significant performance improvements in real-world situations. Thanks for any help!

• Android - Custom Widget doesnt update

  Hi, I'm trying to make a widget to my app, but it doesnt update. I just need to change the textview text and open an activity when a press a button, but none of them works... the code public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) { RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.newswidget); views.setTextViewText(R.id.tvNews, "prueba1"); views.setString(R.id.tvNews, "setText", "prueba3"); Intent intent = new Intent(context, DoctorChatAndroid.class); PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0); views.setOnClickPendingIntent(R.id.ibNext, pendingIntent); for (int i = 0; i < appWidgetIds.length; i++) { appWidgetManager.updateAppWidget(i, views); } the layout <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content"> <ImageButton android:id="@+id/ibNext" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@android:drawable/ic_media_ff" android:layout_alignParentRight="true"/> <ImageButton android:id="@+id/ibLast" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@android:drawable/ic_media_rew" android:layout_toLeftOf="@id/ibNext"/> <TextView android:id="@+id/tvNews" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/nwNoNewAnswer" android:layout_toLeftOf="@id/ibLast"/> </RelativeLayout> the other xml thx a lot!!!

• Is is possible to determine a password input string as plaintext or hashed?

  - by Godders

  I have a RESTful API containing a URI of /UserService/Register. /UserService/Register takes an XML request such as: <UserRegistrationRequest> <Password>password</Password> <Profile> <User> <UserName>username</UserName> </User> </Profile> </UserRegistrationRequest> I have the following questions given the above scenario: Is there a way (using C# and .Net 3.5+) of enforcing/validating that clients calling Register are passing a hashed password rather than plaintext? Is leaving the choice of hashing algorithm to be used to the client a good idea? We could provide a second URI of /UserService/ComputePasswordHash which the client would call before calling /UserService/Register. This has the benefit of ensuring that each password is hashed using the same algorithm. Is there a mechanism within REST to ensure that a client has called one URI before calling another? Hope I've explained myself ok. Many thanks in advance for any help.

• Populating an array into a TableView - Thanks in advance.

  - by tssav

  Hello Developers, View not being populated with the array. I would really appreciate if I could get some help. Thanks!! In a tableView I have the following: NSDictionary *cat = [category objectAtIndex:indexPath.row]; cell.textLabel.text = [cat valueForKey:@"reference"]; This populates the tableView with the content of the array from an XML file. There is another array “data” that prints out the content to the debug console and I want to populate another view with this content. But I am having lot of trouble populating the next view with the data array. NSLog(@"cellForRowAtIndexPath-- Reference:%@: Verse:%@", [cat valueForKey:@"reference"], [cat valueForKey:@"data"]); The didSelectRowAtIndexPath method looks like this: Verse *vvc = [[Verse alloc] initWithNibName:@"VerseView" bundle:nil]; vvc.verses = [[category objectAtIndex:indexPath.row] valueForKey:@"verse"]; [self.navigationController pushViewController:vvc animated:YES]; [vvc release]; [tableView deselectRowAtIndexPath:indexPath animated:YES]; In the cellForRowAtIndexPath of the next view I have the following: NSDictionary *cat = [verses objectAtIndex:indexPath.row]; cell.textLabel.text = [cat valueForKey:@"data"]; What I would like is to have the “data” in a textView. I don’t know what’s wrong. Any help would be appreciated!

• Android: CustomListAdapter

  - by primal

  Hi, I have implemented a custom list view which looks like the twitter timeline. adapter = new MyClickableListAdapter(this, R.layout.timeline, mObjectList); setListAdapter(adapter); The constructor for MyClickableListAdapter is as follows private class MyClickableListAdapter extends ClickableListAdapter{ public MyClickableListAdapter(Context context, int viewId, List objects) { super(context, viewId, objects); } ClickableListAdapter extends BaseAdapter and implements the necessary methods. The xml code for the list view is as follows <ListView android:id="@+id/android:list" android:layout_width="fill_parent" android:layout_height="wrap_content" /> This is what it looks like. I have 3 questions 1) I tried registering a context menu for the list view by adding the line after setting the list adapter registerforContextMenu(getListView()); But on long-click the menu doesnt get displayed. I cannot understand what I am doing wrong! 2) Is it possible to display a textview above the listview? I tried it by adding the code for textview above the listview. But then, only the textview gets displayed. 3) I have seen in many twitter clients that on clicking post a window pops up from the top covering only some portion of the screen and rest of the timeline is visible. How can this be done possibly without starting a new activity? Any help would be much appreciated..

• Servlet Security question about j_security_check, j_username and j_password

  - by Nitesh Panchal

  Hello, I used jdbcRealm in my web application and it's working fine. I defined all constraints also in my web.xml. Like all pages of url pattern /Admin/* should be accessed by only admin. I have a login form with uses standard j_security_check, j_username and j_password. Now, when i type Admin/home.jsf it rightly redirects me login.jsf and there when i type the password i am redirected to home.jsf. This works alright but problem comes i directly go to login.jsf and then type password and username. This time it again redirects me to login.jsf. Is there any way through which i can specify which page to go when successful login is there? I need to specify different different pages for different roles. For Admin, it is /Admin/home.jsf for general users it is /General/home.jsf because login form is shared between different type of users. Where do i specify all these things? Secondly, i want to have a remember me checkbox at the end of login form. How do i do this? By default, it is submitted to j_security_check servlet and i have no control over its execution. Please help. This doesn't seem so hard but looks like i am missing something.

• Visual Studio / Blend... how you organize that?

  - by TomTom

  Virst time more complex stuff in WPF. I am a little lost on the split betwen VS and Blend. It seems I am VERY limited with editors in Visual Studio for editing controls - when customizing, for example, it seems I Can enter astyle in XML... but in blend I Can tell it to make a copy of the CURRENT style and use that as a starter, definitely more convenient. I understand the "difference in focus", but it seems to me that i Really need both tools to work, especially if the controls I Do are: More complex Not user controls "on purpose" (to allow more customization by programmes using the application). THis means when I do a control, my approach would be: Work on the backend as good as it gets without front end (i.e. implement all methods needed etc., but can be dummies) Switch over to Blend (closing visual studio - as the projcet must be closed) Put in the initial templating Switch over to VIsual Studio (closing blend) Put logic in and debug. This seems pretty counterintuitively. Am I missing something obvious here?

• LDAP/AD Integrated Group/Membership Management Package suitable for embedding in an application

  - by Ernest

  In several web applications, it is often necessary to define groups of users for purposes of membership as well as role management. For example, in one of our applications we would like to user a group of "Network Engineers" and another group that consists of "Managers" of such Network Engineers. The information we need is contact details of members of each group. So far, we have written our own tools to allow the administrator of the application to add/delete/move groups and their memberships and either store them in a XML file or a database. Increasingly, companies already have the groups we want defined in LDAP/AD, so it would be best to create a pointer in our application to the correspoding group in LDAP. Although there are a number of LDAP libraries and LDAP browsers available and we could code this and provide a web front end to get a list of available groups and their members, we are wondering if there is already a "component framework" available that would readily provide this LDAP browsing functionality that we could just embed this into our application. Something between a library and a full LDAP browser product ? (To clarify, the use case is for an admin of our web application to create a locally relevant group name and then map it to an exiting LDAP group. To enable this in the UI, we would like to present a way for the admin to browse available groups in the company LDAP server, view their membership, and select the LDAP group they would like to map to the locally relevant group name. In a second step, we would then synchronize the members of that LDAP group and their contact details to a store in our application ) Appreciate any pointers.

• Dynamically disable custom (VBA) Excel context menu buttons?

  - by Lopsided

  The Scenario Hi guys, I am about to add a few custom controls to the cell context menu in my Excel workbook using the instructions found on this MSDN page. The only problem I am having is that I need the items to only be enabled for a specific column/range of cells. I've looked around, and I've been unable to find any steps for this--there are some for VSTO development (written in C#), but that is not what I need. I plan to write this using the VBA IDE built into Office, and perhaps a bit of XML using the Custom UI Editor. The Question So basically, I'm looking for a way to run a function at the time the context menu is called (i.e., upon right-click) that validates the selection to make sure it is in the appropriate column. If it isn't, I would like my custom buttons to be greyed out. P.S. Please don't think I am asking you to write my code. Creating these buttons should be very simple, as I have created many before (albeit they were all Ribbon items), and I hope it is okay to ask for some quick assistance on this very specific issue. Thank you in advance!

• Using EhCache for session.createCriteria(...).list()

  - by James Smith

  I'm benchmarking the performance gains from using a 2nd level cache in Hibernate (enabling EhCache), but it doesn't seem to improve performance. In fact, the time to perform the query slightly increases. The query is: session.createCriteria(MyEntity.class).list(); The entity is: @Entity @Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE) public class MyEntity { @Id @GeneratedValue private long id; @Column(length=5000) private String data; //---SNIP getters and setters--- } My hibernate.cfg.xml is: <!-- all the normal stuff to get it to connect & map the entities plus:--> <property name="hibernate.cache.region.factory_class"> net.sf.ehcache.hibernate.EhCacheRegionFactory </property> The MyEntity table contains about 2000 rows. The problem is that before adding in the cache, the query above to list all entities took an average of 65 ms. After the cache, they take an average of 74 ms. Is there something I'm missing? Is there something extra that needs to be done that will increase performance?

• jQuery pagination without all the rows of data before hand

  - by Aaron Mc Adam

  Hi guys, I'm trying to find a solution for paginating my search results. I have a built the links and everything works without jQuery. I've also got AJAX working for the links, but I just need a way of tidying up the list of links, as some search results return up to 60 pages and the links spread to two rows in my template. I am searching the Amazon API, and can only return 10 results at a time. Upon clicking the pagination links, the next 10 results are returned. I have access to the total results number from the XML, but not all the data at once, so I can't put all the data into a "hiddenResults" div that the jQuery Pagination plugin needs. Here is the jQuery I have for the pagination: var $pagination = $("#pagination ul"); $pagination.delegate('.pagenumbers', 'click', function() { var $$this = $(this); $$this.closest('li').addClass('cached'); $pagination.find("#currentPage").removeAttr('id').wrapInner($('<a>', {'class':'pagenumbers', 'href':'book_data.php?keywords='+keywords})); $$this.closest('li').attr('id','currentPage').html( $$this.text() ); $.ajax({ type : "GET", cache : false, url : "book_data.php", data : { keywords : keywords, page : $$this.text() }, success : show_results }); return false; }); function show_results(res) { $("#searchResults").replaceWith($(res).find('#searchResults')).find('table.sortable tbody tr:odd').addClass('odd'); detailPage(); selectForm(); if ( ! ( $pagination.find('li').hasClass('cached') ) ) { $.get("book_data.php", { keywords : keywords, page : ( $pagination.find("#currentPage").text() + 1 ) } ); } }

• Projects integration question

  - by qkrsppopcmpt

  Other team has one legacy system, which is data aggregators. It is implemented as web service using JAVA, SOAP,MTOM,Tomcat and Axis2. They have wsdl files defining functionalities such as search, retrieve data, upload, download. Our team has a new developed website which is developed using RoR with mySQL. It is sort of social networking. Users can register, add friends, upload images, videos. Also, they can search data. We are required to connect the two systems. One possible solution I think is - Adding components into our website. The component invoke services on the aggregators. - Synchronize website database to the aggregators. My doubts are: 1. How to add components in our websites? The components should use Java or Ruby or adapter from java to ruby. It is possible using ruby invoke web service. I think it should work since it is the point of web service. If so, can ruby call those services in wsdl directly? But how to deal with those different data structure? How to synchroinze our database to the aggregators. I think the best way is also through web service invocation such as upload. That means, we have to export the db records into xml files and then write some tools to upload. The web service project support MTOM. So, it is fine to upload huge data. Am I on the right record? Can anybody give me some hint. Thanks.

• Are there good reasons not to use an ORM?

  - by hangy

  During my apprenticeship, I have used NHibernate for some smaller projects which I mostly coded and designed on my own. Now, before starting some bigger project, the discussion arose how to design data access and whether or not to use an ORM layer. As I am still in my apprenticeship and still consider myself a beginner in enterprise programming, I did not really try to push in my opinion, which is that using an object relational mapper to the database can ease development quite a lot. The other coders in the development team are much more experienced than me, so I think I will just do what they say. :-) However, I do not completely understand two of the main reasons for not using NHibernate or a similar project: One can just build one’s own data access objects with SQL queries and copy those queries out of Microsoft SQL Server Management Studio. Debugging an ORM can be hard. So, of course I could just build my data access layer with a lot of SELECTs etc, but here I miss the advantage of automatic joins, lazy-loading proxy classes and a lower maintenance effort if a table gets a new column or a column gets renamed. (Updating numerous SELECT, INSERT and UPDATE queries vs. updating the mapping config and possibly refactoring the business classes and DTOs.) Also, using NHibernate you can run into unforeseen problems if you do not know the framework very well. That could be, for example, trusting the Table.hbm.xml where you set a string’s length to be automatically validated. However, I can also imagine similar bugs in a “simple” SqlConnection query based data access layer. Finally, are those arguments mentioned above really a good reason not to utilise an ORM for a non-trivial database based enterprise application? Are there probably other arguments they/I might have missed? (I should probably add that I think this is like the first “big” .NET/C# based application which will require teamwork. Good practices, which are seen as pretty normal on Stack Overflow, such as unit testing or continuous integration, are non-existing here up to now.)

• How to display recently view items in iphone

  - by Pugal Devan

  Hi friends, I have created tab bar and have three views. Tab-1 --> table view and it navigates to detail table view. Tab-2 --> map view. Tab-3 --> table view.(Recent view for Tab-1 items). Now i have displayed the names in the table view in tab-1. The names are changed dynamically and displayed using XML parsing. In tab-3 is the recent view. Now i want to display the details in recent view those who visit recently in tab-1 view. I want to display only 10 items in the recent view. So i have used NSMutableArray and i have set deleagtes due to get the items in recent view from tab-1 view. How to avoid the duplicate recent items and how to remove the older items and inserts the new recent items in recent view. Here my sample code, In Recent view class, stories = [[NSMutableArray alloc] initWithCapacity:10]; items = [[NSMutableDictionary alloc] init]; NSString *preferName = [devDelegate getCurrentAuthor]; //(get name dynamically) [items setObject:preferName forKey:@"preferName"]; [stories addObject:[items copy]]; cell.textLabel.text = [[stories objectAtIndex:storyIndex] objectForKey:@"preferName"]; So please guide me to how to achieve this. Thanks.
