  • Context menu opens slowly in Explorer in Windows 7, why?

    - by xxzoid
    I'm running a Windows 7 on my reasonably modern laptop, when I open the context menu in Windows Explorer it really takes it time to show up (~10 seconds). There are some programs that have their commands added to it (an archive manipulation utility, an antivirus, a version control system and such). I think one of them freezes the operation. Is there a benchmark tool to measure it somehow or a tool to turn them off by one in Explorer without uninstalling them (which would be a penultimate measure, because use them)?

  • Fedora 13 becomes unresponsive when too many applications running.

    - by user61766
    I am using Fedora 13 64bit on Dell Vostro full 4GB RAM system with default Gnome GUI. This is very annoying problem that I don't how to fix except by rebooting the whole PC. When I have too many applications running ( like browser windows), the system start acting sluggish. The fist symptoms appear in Eclipse IDE which becomes so terrible it just becomes frozen for sometime one whole minute after I try to edit something in the editor. Then Firefox seems like it has crashed. Google Chrome becomes very unresponsive as well. All GUI applications including File manager becomes unresponsive. When I check System Monitor, the CPU is still around 20% and memory is at 80% but the system seems getting fried up. This progressively becomes worse until I soft reboot it or if I dont do it evetually the whole system is fried, no response to any keyboard key or mouse and I have to hit the hardware turn off button. I regularly yum update the system but this makes no difference. Please don't tell not to run too many applications because I need those for my work. I thought Linux is well designed Operating System but I am very disappointed so far. Can some one here help ?

  • How to give the menus associated with dojo's dijit.ComboBox different css from those of dijit.Menu

    - by sprugman
    When you use a dijit.ComboBox, the type ahead suggestions get implemented as a dijit.Menu. I've got a design which calls for the matched portion of the suggestion rows to be normal, and the unmatched portion to be bold. The structure that dojo creates is like this: <ul class="dijitReset dijitMenu"> <li role="option" class="dijitReset dijitMenuItem"> <span class="dijitComboBoxHighlightMatch">Ch</span>oice One </li> <li role="option" class="dijitReset dijitMenuItem"> <span class="dijitComboBoxHighlightMatch">Ch</span>oice Two </li> </ul> So I can target the matched part, but not the unmatched part. So my css needs to be something like: .dijitMenuItem { font-weight: bold; } .dijitMenuItem .dijitComboBoxHighlightMatch { font-weight: normal; } The problem is, if I do that, all menus will be bolded, and I don't want that. Just doing something like this: <select dojoType="dijit.form.ComboBox" class="foobar">[options]</select> puts the foobar class in the ComboBox, but the menu is an independent node not under that hierarchy. What's the easiest way to add a css class around the popup menu that the ComboBox generates?

  • AS3 How do I stop sound and video when clicking a menu button to go to another frame?

    - by Jennifer Heidelberg
    Hello, I have a problem with my slideshow script. I have embedding a flash video file into my website with this slideshow called monoslideshow, and everything seems to work perfectly. Trouble is, when I am clicking on another menu button that should jump to another frame, it still keeps playing the video and sound while displaying the new menu data. So I will probably need some code that stops the video instantly, when another menu button is clicked. But how do I write it and where do I put it? Here is my actionscript for the video file to show: var loaderSlide:Loader = new Loader(); var monoslideshow:Object; loaderSlide.contentLoaderInfo.addEventListener(Event.COMPLETE, onLoadComplete); addChild(loaderSlide); loaderSlide.load(new URLRequest("monoslideshow.swf")); function onLoadComplete(event:Event):void { monoslideshow = event.target.content; monoslideshow.showLogo = false; monoslideshow.setViewport(new Rectangle(730, 20, 700, 660)); var xml:XML = <album title="TITLE" itemPath="photography/makingoff/" thumbnailPath="thumbnails/"> <contents> <video source="VIDEO.flv" /> </contents> </album> monoslideshow.loadXML(xml); } It would be great to get a solution to this problem, otherwise my website will be kinda messy ;) THANK YOU!!

  • Create a subtitle for menu items in Silverstripe CMS?

    - by ELF
    Hi I'm using Silverstripe CMS on the "Simple" template. I'm wondering how to create subtitles for the menu items. The current navigation template is like so: <nav class="primary"> <span class="nav-open-button">²</span> <ul> <% loop $Menu(2) %> <li class="$LinkingMode"><a href="$Link" title="$Title.XML">$MenuTitle.XML</a></li> <% end_loop %> </ul> I'm thinking i could somehow edit $Menutitle.XML but how? Also the sub title should be displayed directly under the Title but as the same button. The SubTitle would need to have a different css rule so that it could be smaller. I know that the CMS has an area for me to edit the page titles which become the menu titles, would it be easy to add a subtitle to the admin like that or is there some other easier way? I only need to make a few of them.

  • UK OUG Conference Highlights and Insights

    - by Richard Bingham
    As per my preemptive post, this was the first time the annual conference organized by the UK Oracle User Group (UKOUG) was split into two events, one for Oracle Applications and another in December for Oracle Technology. Apps13, as it was branded, was hailed as a success, with over 1000 registered attendees and three days of sessions, exhibition, round-tables and many other types of content. As this poster on their stand illustrates, the UKOUG is a strong community with popular participants from both big and small Oracle partners and customers. The venue was a more intimate setting than previous years also, allowing everyone to casually bump into those they hoped to. It gave a real feeling of an Apps Community. The main themes over the days where CRM and Customer Experience, HCM, and FIN/SCM. This allowed people to attend just one focused day if they wanted. In addition the Apps Transformation stream ran across all three days, offering insights, advice, and details on the newer product solutions like Fusion Applications.  Here are some of the key take-aways I got from the conference, specific to my role in Fusion Applications Developer Relations: User Experience continues to be a significant reason for adopting some of the newer application products available, with immediately obvious gains in user productivity and satisfaction reported by customers. Also this doesn't stop with the baked-in UX either, with their Design Patterns proving popular and indeed currently being extended to including things like extending on ADF mobile and customizing the Simplified UI. More on this to come from us soon. The executive sessions emphasized the "it's a journey" phrase, illustrating that modern business applications are powered by technologies such as Cloud, Mobile, Social and Big Data and these can be harnessed to help propel your organization forward. Indeed the emphasis is away from the traditional vendor prescribed linear applications road map, and towards plotting a course based on business priorities supported by a broad range of integrated solutions. To help with this several conference sessions demoed the new "Applications Navigator" tool, developed in partnership with OUG members, which offers a visual framework to help organizations plan their Oracle Applications investments around business and technology imperatives. Initial reaction was positive, especially as customers do not need to decipher Oracle's huge product catalog and embeds the best blend of proven and integrated applications solutions. We'll share more on this when it is generally available. Several sessions focused around explanations and interpretation of Oracle OpenWorld 2013, helping highlight the key Oracle Applications messages and directions. With a relative small percentage of conference attendees also at OpenWorld (from a show of hands) this was a popular way to distill the information available down into specific items of interest for the community. Please note the original OpenWorld 2013 content is still available for download but will not remain available forever (via the Oracle website OpenWorld Content Catalog > pick a session > see the PDF download). With the release of E-Business Suite 12.2 the move to develop and deploy on the Fusion Middleware stack becomes a reality for many Oracle Applications customers. This coupled with recent E-Business Suite features such as the Integrated SOA Gateway and the E-Business Suite SDK for Java, illustrates how the gap between the technologies and techniques involved in extending E-Business Suite and Fusion Applications is quickly narrowing. We'll see this merging continue to evolve going forwards. Getting started with Oracle Cloud Applications is actually easier than many customers expected, with a broad selection of both large and medium sized organizations explaining how they added new features to their existing Oracle Applications portfolios. New functionality available from Fusion HCM and CX are popular extensions that do not have to disrupt those core business services. Coexistence is the buzzword here, and the available integration is also simpler than many expected, commonly involving an initial setup data load, then regularly incremental synchronizations, often without a need for real-time constant communication between systems. With much of this pre-built already the implementation process is also quite rapid. With most people dressed in suits, we wanted to get the conversations going without the traditional english reserve, so we decided to make ourselves a bit more obvious, as the photo below shows. This seemed to be quite successful and helped those interested identify and approach us. Keep a look out for similar again. In fact if you're in the UK there is an "Apps Transformation Day" planned by the UKOUG for the 19th March 2014, with more details to follow. Again something we'll be sure to participate in. I am hoping to attend the next half of the UKOUG annual conference, Tech13, that focuses more on Oracle technology and where there is more likely to be larger attendance of those interested in the lower-level aspects of applications customization and development. If you're going, let me know and maybe we can meet up.

  • Oracle WebCenter: Common User Experience Architecture

    - by kellsey.ruppel(at)oracle.com
    You may remember that the key goals of the new release of WebCenter are providing a Modern User Experience, unparalleled Application Integration, converging all the best of the existing portal platforms into WebCenter and delivering a Common User Experience Architecture.  In previous weeks we've provided an overview of Oracle WebCenter and discussed some of the other key goals and this week, we'll focus on how the new release of Oracle WebCenter delivers a Common User Experience Architecture.When Oracle talks about a Common User Experience Architecture, it really focuses on a core set of areas.  First, the way that information is accessed needs to be consistent and extensible so that as requirements change, the applications don't need to be rewritten for every change. Second, this information access layer needs to be securely accessible to any application, site, or any other channel that needs to leverage this information.  Third, there needs to be a consistent presentation layout, Oracle calls it a UI shell, so that all resources can fit together in a useable, productive way.  Fourth, there needs to be a common set of design patterns for how different menus, features, and services fit into this UI Shell for broad and productive usability.  Fifth, there needs to be a set of design patterns for the individual services that plug into this UI shell so that end users can move from one module of the application to another without new learning.  Finally, all of these layers need to be customizable in an easy way that insulates IT from patching and upgrading problems and allows the business owners the agility to quickly change with the market conditions.As Oracle has already announced, we will release our next generation of enterprise applications called Oracle Fusion Applications.  We have thousands of developers building these applications that all had different programming tool experience and UI design experience.  We've educated over 6,000 developers building Oracle Fusion Applications to leverage these Common User Experience Architecture patterns to speed their learning curve of the new Java standards as well as SOA principles to deliver a revolutionary new set of applications.  You could imagine the big challenge with getting all these developers with different backgrounds and different UI design skills to deliver a completely integrated application user experience.  This is why Oracle invested heavily in designing this Common User Experience Architecture, based on Oracle WebCenter and the Oracle Application Development Framework (ADF).  It pulls together the best practices and design patterns that Oracle development required in order to bring Fusion Applications to market and Oracle WebCenter is the user experience layer that all of this is surfaced through.  In this way, customers can quickly brand a deployment for new partnerships without having to redevelop a new site.  Or they can quickly add new options to the UI Shell to enable their line of business managers to quickly adapt to a new competitive product.  And with the core integration of the activities to produce a Business Activity Stream, customers are able to stay on top of all their key business actions when they happen as they happen and more importantly, the system can recommend actions or resources to help act on these activities.And we've authored this whole set of design patterns for Oracle development to take advantage of in delivering Fusion Applications.  We're also applying these design patterns to our existing eBusiness Suite, Peoplesoft, Siebel, and JD Edwards applications so that they can tie in the exact same way that Fusion Applications has been brought together.  This will provide customers with a complete Common User Experience Architecture for their entire ecosystem of applications within their enterprise whether they are from Oracle, another vender, or custom built applications. And this is all provided in the new release of Oracle WebCenter.  These design patterns cover elements around delivering a complete, aggregated menu of all the capabilities that their role allows independent of which application they are trying to access.   It means that as they move from one application to another, they will have a consistent user experience.  And if they are using an Oracle application, any customizations that are made to the application are preserved and managed through upgrades and patches.Be sure to check back this week as we share more information and resources on Oracle's Common User Experience Architecture.

  • TOTD #166: Using NoSQL database in your Java EE 6 Applications on GlassFish - MongoDB for now!

    - by arungupta
    The Java EE 6 platform includes Java Persistence API to work with RDBMS. The JPA specification defines a comprehensive API that includes, but not restricted to, how a database table can be mapped to a POJO and vice versa, provides mechanisms how a PersistenceContext can be injected in a @Stateless bean and then be used for performing different operations on the database table and write typesafe queries. There are several well known advantages of RDBMS but the NoSQL movement has gained traction over past couple of years. The NoSQL databases are not intended to be a replacement for the mainstream RDBMS. As Philosophy of NoSQL explains, NoSQL database was designed for casual use where all the features typically provided by an RDBMS are not required. The name "NoSQL" is more of a category of databases that is more known for what it is not rather than what it is. The basic principles of NoSQL database are: No need to have a pre-defined schema and that makes them a schema-less database. Addition of new properties to existing objects is easy and does not require ALTER TABLE. The unstructured data gives flexibility to change the format of data any time without downtime or reduced service levels. Also there are no joins happening on the server because there is no structure and thus no relation between them. Scalability and performance is more important than the entire set of functionality typically provided by an RDBMS. This set of databases provide eventual consistency and/or transactions restricted to single items but more focus on CRUD. Not be restricted to SQL to access the information stored in the backing database. Designed to scale-out (horizontal) instead of scale-up (vertical). This is important knowing that databases, and everything else as well, is moving into the cloud. RBDMS can scale-out using sharding but requires complex management and not for the faint of heart. Unlike RBDMS which require a separate caching tier, most of the NoSQL databases comes with integrated caching. Designed for less management and simpler data models lead to lower administration as well. There are primarily three types of NoSQL databases: Key-Value stores (e.g. Cassandra and Riak) Document databases (MongoDB or CouchDB) Graph databases (Neo4J) You may think NoSQL is panacea but as I mentioned above they are not meant to replace the mainstream databases and here is why: RDBMS have been around for many years, very stable, and functionally rich. This is something CIOs and CTOs can bet their money on without much worry. There is a reason 98% of Fortune 100 companies run Oracle :-) NoSQL is cutting edge, brings excitement to developers, but enterprises are cautious about them. Commercial databases like Oracle are well supported by the backing enterprises in terms of providing support resources on a global scale. There is a full ecosystem built around these commercial databases providing training, performance tuning, architecture guidance, and everything else. NoSQL is fairly new and typically backed by a single company not able to meet the scale of these big enterprises. NoSQL databases are good for CRUDing operations but business intelligence is extremely important for enterprises to stay competitive. RDBMS provide extensive tooling to generate this data but that was not the original intention of NoSQL databases and is lacking in that area. Generating any meaningful information other than CRUDing require extensive programming. Not suited for complex transactions such as banking systems or other highly transactional applications requiring 2-phase commit. SQL cannot be used with NoSQL databases and writing simple queries can be involving. Enough talking, lets take a look at some code. This blog has published multiple blogs on how to access a RDBMS using JPA in a Java EE 6 application. This Tip Of The Day (TOTD) will show you can use MongoDB (a document-oriented database) with a typical 3-tier Java EE 6 application. Lets get started! The complete source code of this project can be downloaded here. Download MongoDB for your platform from here (1.8.2 as of this writing) and start the server as: arun@ArunUbuntu:~/tools/mongodb-linux-x86_64-1.8.2/bin$./mongod./mongod --help for help and startup optionsSun Jun 26 20:41:11 [initandlisten] MongoDB starting : pid=11210port=27017 dbpath=/data/db/ 64-bit Sun Jun 26 20:41:11 [initandlisten] db version v1.8.2, pdfile version4.5Sun Jun 26 20:41:11 [initandlisten] git version:433bbaa14aaba6860da15bd4de8edf600f56501bSun Jun 26 20:41:11 [initandlisten] build sys info: Linuxbs-linux64.10gen.cc 2.6.21.7-2.ec2.v1.2.fc8xen #1 SMP Fri Nov 2017:48:28 EST 2009 x86_64 BOOST_LIB_VERSION=1_41Sun Jun 26 20:41:11 [initandlisten] waiting for connections on port 27017Sun Jun 26 20:41:11 [websvr] web admin interface listening on port 28017 The default directory for the database is /data/db and needs to be created as: sudo mkdir -p /data/db/sudo chown `id -u` /data/db You can specify a different directory using "--dbpath" option. Refer to Quickstart for your specific platform. Using NetBeans, create a Java EE 6 project and make sure to enable CDI and add JavaServer Faces framework. Download MongoDB Java Driver (2.6.3 of this writing) and add it to the project library by selecting "Properties", "LIbraries", "Add Library...", creating a new library by specifying the location of the JAR file, and adding the library to the created project. Edit the generated "index.xhtml" such that it looks like: <h1>Add a new movie</h1><h:form> Name: <h:inputText value="#{movie.name}" size="20"/><br/> Year: <h:inputText value="#{movie.year}" size="6"/><br/> Language: <h:inputText value="#{movie.language}" size="20"/><br/> <h:commandButton actionListener="#{movieSessionBean.createMovie}" action="show" title="Add" value="submit"/></h:form> This page has a simple HTML form with three text boxes and a submit button. The text boxes take name, year, and language of a movie and the submit button invokes the "createMovie" method of "movieSessionBean" and then render "show.xhtml". Create "show.xhtml" ("New" -> "Other..." -> "Other" -> "XHTML File") such that it looks like: <head> <title><h1>List of movies</h1></title> </head> <body> <h:form> <h:dataTable value="#{movieSessionBean.movies}" var="m" > <h:column><f:facet name="header">Name</f:facet>#{m.name}</h:column> <h:column><f:facet name="header">Year</f:facet>#{m.year}</h:column> <h:column><f:facet name="header">Language</f:facet>#{m.language}</h:column> </h:dataTable> </h:form> This page shows the name, year, and language of all movies stored in the database so far. The list of movies is returned by "movieSessionBean.movies" property. Now create the "Movie" class such that it looks like: import com.mongodb.BasicDBObject;import com.mongodb.BasicDBObject;import com.mongodb.DBObject;import javax.enterprise.inject.Model;import javax.validation.constraints.Size;/** * @author arun */@Modelpublic class Movie { @Size(min=1, max=20) private String name; @Size(min=1, max=20) private String language; private int year; // getters and setters for "name", "year", "language" public BasicDBObject toDBObject() { BasicDBObject doc = new BasicDBObject(); doc.put("name", name); doc.put("year", year); doc.put("language", language); return doc; } public static Movie fromDBObject(DBObject doc) { Movie m = new Movie(); m.name = (String)doc.get("name"); m.year = (int)doc.get("year"); m.language = (String)doc.get("language"); return m; } @Override public String toString() { return name + ", " + year + ", " + language; }} Other than the usual boilerplate code, the key methods here are "toDBObject" and "fromDBObject". These methods provide a conversion from "Movie" -> "DBObject" and vice versa. The "DBObject" is a MongoDB class that comes as part of the mongo-2.6.3.jar file and which we added to our project earlier.  The complete javadoc for 2.6.3 can be seen here.

  • TOTD #166: Using NoSQL database in your Java EE 6 Applications on GlassFish - MongoDB for now!

    - by arungupta
    The Java EE 6 platform includes Java Persistence API to work with RDBMS. The JPA specification defines a comprehensive API that includes, but not restricted to, how a database table can be mapped to a POJO and vice versa, provides mechanisms how a PersistenceContext can be injected in a @Stateless bean and then be used for performing different operations on the database table and write typesafe queries. There are several well known advantages of RDBMS but the NoSQL movement has gained traction over past couple of years. The NoSQL databases are not intended to be a replacement for the mainstream RDBMS. As Philosophy of NoSQL explains, NoSQL database was designed for casual use where all the features typically provided by an RDBMS are not required. The name "NoSQL" is more of a category of databases that is more known for what it is not rather than what it is. The basic principles of NoSQL database are: No need to have a pre-defined schema and that makes them a schema-less database. Addition of new properties to existing objects is easy and does not require ALTER TABLE. The unstructured data gives flexibility to change the format of data any time without downtime or reduced service levels. Also there are no joins happening on the server because there is no structure and thus no relation between them. Scalability and performance is more important than the entire set of functionality typically provided by an RDBMS. This set of databases provide eventual consistency and/or transactions restricted to single items but more focus on CRUD. Not be restricted to SQL to access the information stored in the backing database. Designed to scale-out (horizontal) instead of scale-up (vertical). This is important knowing that databases, and everything else as well, is moving into the cloud. RBDMS can scale-out using sharding but requires complex management and not for the faint of heart. Unlike RBDMS which require a separate caching tier, most of the NoSQL databases comes with integrated caching. Designed for less management and simpler data models lead to lower administration as well. There are primarily three types of NoSQL databases: Key-Value stores (e.g. Cassandra and Riak) Document databases (MongoDB or CouchDB) Graph databases (Neo4J) You may think NoSQL is panacea but as I mentioned above they are not meant to replace the mainstream databases and here is why: RDBMS have been around for many years, very stable, and functionally rich. This is something CIOs and CTOs can bet their money on without much worry. There is a reason 98% of Fortune 100 companies run Oracle :-) NoSQL is cutting edge, brings excitement to developers, but enterprises are cautious about them. Commercial databases like Oracle are well supported by the backing enterprises in terms of providing support resources on a global scale. There is a full ecosystem built around these commercial databases providing training, performance tuning, architecture guidance, and everything else. NoSQL is fairly new and typically backed by a single company not able to meet the scale of these big enterprises. NoSQL databases are good for CRUDing operations but business intelligence is extremely important for enterprises to stay competitive. RDBMS provide extensive tooling to generate this data but that was not the original intention of NoSQL databases and is lacking in that area. Generating any meaningful information other than CRUDing require extensive programming. Not suited for complex transactions such as banking systems or other highly transactional applications requiring 2-phase commit. SQL cannot be used with NoSQL databases and writing simple queries can be involving. Enough talking, lets take a look at some code. This blog has published multiple blogs on how to access a RDBMS using JPA in a Java EE 6 application. This Tip Of The Day (TOTD) will show you can use MongoDB (a document-oriented database) with a typical 3-tier Java EE 6 application. Lets get started! The complete source code of this project can be downloaded here. Download MongoDB for your platform from here (1.8.2 as of this writing) and start the server as: arun@ArunUbuntu:~/tools/mongodb-linux-x86_64-1.8.2/bin$./mongod./mongod --help for help and startup optionsSun Jun 26 20:41:11 [initandlisten] MongoDB starting : pid=11210port=27017 dbpath=/data/db/ 64-bit Sun Jun 26 20:41:11 [initandlisten] db version v1.8.2, pdfile version4.5Sun Jun 26 20:41:11 [initandlisten] git version:433bbaa14aaba6860da15bd4de8edf600f56501bSun Jun 26 20:41:11 [initandlisten] build sys info: Linuxbs-linux64.10gen.cc 2.6.21.7-2.ec2.v1.2.fc8xen #1 SMP Fri Nov 2017:48:28 EST 2009 x86_64 BOOST_LIB_VERSION=1_41Sun Jun 26 20:41:11 [initandlisten] waiting for connections on port 27017Sun Jun 26 20:41:11 [websvr] web admin interface listening on port 28017 The default directory for the database is /data/db and needs to be created as: sudo mkdir -p /data/db/sudo chown `id -u` /data/db You can specify a different directory using "--dbpath" option. Refer to Quickstart for your specific platform. Using NetBeans, create a Java EE 6 project and make sure to enable CDI and add JavaServer Faces framework. Download MongoDB Java Driver (2.6.3 of this writing) and add it to the project library by selecting "Properties", "LIbraries", "Add Library...", creating a new library by specifying the location of the JAR file, and adding the library to the created project. Edit the generated "index.xhtml" such that it looks like: <h1>Add a new movie</h1><h:form> Name: <h:inputText value="#{movie.name}" size="20"/><br/> Year: <h:inputText value="#{movie.year}" size="6"/><br/> Language: <h:inputText value="#{movie.language}" size="20"/><br/> <h:commandButton actionListener="#{movieSessionBean.createMovie}" action="show" title="Add" value="submit"/></h:form> This page has a simple HTML form with three text boxes and a submit button. The text boxes take name, year, and language of a movie and the submit button invokes the "createMovie" method of "movieSessionBean" and then render "show.xhtml". Create "show.xhtml" ("New" -> "Other..." -> "Other" -> "XHTML File") such that it looks like: <head> <title><h1>List of movies</h1></title> </head> <body> <h:form> <h:dataTable value="#{movieSessionBean.movies}" var="m" > <h:column><f:facet name="header">Name</f:facet>#{m.name}</h:column> <h:column><f:facet name="header">Year</f:facet>#{m.year}</h:column> <h:column><f:facet name="header">Language</f:facet>#{m.language}</h:column> </h:dataTable> </h:form> This page shows the name, year, and language of all movies stored in the database so far. The list of movies is returned by "movieSessionBean.movies" property. Now create the "Movie" class such that it looks like: import com.mongodb.BasicDBObject;import com.mongodb.BasicDBObject;import com.mongodb.DBObject;import javax.enterprise.inject.Model;import javax.validation.constraints.Size;/** * @author arun */@Modelpublic class Movie { @Size(min=1, max=20) private String name; @Size(min=1, max=20) private String language; private int year; // getters and setters for "name", "year", "language" public BasicDBObject toDBObject() { BasicDBObject doc = new BasicDBObject(); doc.put("name", name); doc.put("year", year); doc.put("language", language); return doc; } public static Movie fromDBObject(DBObject doc) { Movie m = new Movie(); m.name = (String)doc.get("name"); m.year = (int)doc.get("year"); m.language = (String)doc.get("language"); return m; } @Override public String toString() { return name + ", " + year + ", " + language; }} Other than the usual boilerplate code, the key methods here are "toDBObject" and "fromDBObject". These methods provide a conversion from "Movie" -> "DBObject" and vice versa.

    Hello, I can't touch any button in my UIActionSheet. If I copy/paste this code in a new project, it works as expected. I'm forcing the First Responder = doesn't work I'm using [menu showFromTabBar:self.tabBarController.tabBar]; = doesn't work I'm using [menu showInView:self.view.window]; = doesn't work UIActivityIndicatorView *progressView = [[UIActivityIndicatorView alloc] initWithFrame:CGRectMake(150, 105, 25, 25)]; progressView.activityIndicatorViewStyle = UIActivityIndicatorViewStyleWhiteLarge; UIActionSheet *menu = [[UIActionSheet alloc] initWithTitle:@"first_time_loading" delegate:self cancelButtonTitle:@"device_stop_info" destructiveButtonTitle:nil otherButtonTitles:nil]; [menu addSubview:progressView]; [menu setTag:9]; [menu becomeFirstResponder]; [menu showInView:self.view]; // [menu becomeFirstResponder]; [menu setBounds:CGRectMake(0,0,320, 175)]; [progressView startAnimating]; [progressView hidesWhenStopped]; [menu becomeFirstResponder]; Don't know where to look for more ideas ...
