• JSF 2.0: Validate equality of 2 InputSecret Fields (confirm password) without writing Code?

  - by yournamehere

  I'm developing a pure JavaEE6 application with JSF 2.0 and Glassfish. My JSF implementation is Primefaces (beside Mojarra provided by Glassfish). I want to verify if the values of 2 password fields in a JSF form are equal. With Seam, there is the neat component <s:validateEquality for="pw1"/>. I want do to the same without Seam, just using JSF (or maybe a component of a JSF library). Until now i only saw examples which validate the form with a custom validator. But i would like to compare the fields without writing Java code or Javascript code. Is that possible? This what it looks like with Seam: ... <h:inputSecret id="passwort" value="#{personHome.instance.password}" redisplay="true" required="true"> <f:validateLength minimum="8"/> <a:support event="onblur" reRender="passwortField" bypassUpdates="true" ajaxSingle="true" /> </h:inputSecret> ... <h:inputSecret id="passwort2" required="true" redisplay="true"> <!-- find the JSF2.0-equivalent to this tag: --> <s:validateEquality for="passwort"/> <a:support event="onblur" reRender="passwort2Field" bypassUpdates="true" ajaxSingle="true" /> </h:inputSecret> ... Any help is appreciated. Thanks!

• What is the best Binary Decision Diagram library for Java?

  - by reprogrammer

  A Binary Decision Diagram (BDD) is a data structure to represent boolean functions. I'd like use this data structure in a Java program. My search for Java based BDD libraries resulted into the following packages. Java Decision Diagram Libraries JavaBDD JDD JBDD bddbddb If you know of any other BDD libraries available for Java programs, please let me know so that I add it to the list above. If you have used any of these libraries, please tell me about your experience with the library. In particular, I'd like you to compare the available libraries along the following dimensions. Quality. Is the library mature and reasonably bug free? Performance. How do you evaluate the performance of the library? Support. Could you easily get support whenever you encountered a problem with the library? Was the library well documented? Ease of use. Was the API well designed?

• Debian Simple Gui for adding/removing users for protective directories

  - by ErocM

  We have a hosted site with a directory that is password protected. I need to have a user who knows very little about computers, maintain the users that have access to this directory. The list is going to get big, according to our customer database. My question is 2 fold: Is there a simple gui program that I can have this user utilize to be able to maintain the users without having to teach them how to use ssh and UNIX? Am I going about this the right way? Is there a better way to do this? Thanks for your help!

• Is it possible to rent an IP address to mask the server real IP address?

  - by net-girl

  A customer would like to lease an IP address and point it to a dedicated web server with the intention of "masking" the server's IP address so it would be difficult to tell where the site is hosted. I found a company that leases IP addresses here: http://www.webhostingtalk.com/showthread.php?t=1191688 Is this even possible? Can they rent an IP address from a 3rd party in order to hide the server's IP address? Update: My client will be hosting a government leaks site and is trying to become Raid-Proof similar to what the pirate bay did: http://torrentfreak.com/pirate-bay-moves-to-the-cloud-becomes-raid-proof-121017/ Only that I'm worried about using a reverse proxy because of the latency it could cause having the app servers hosted in one data center and the load balancer/reverse proxy in other and also having to pay twice for bandwidth.

• How to upgrade all dependencies to a specific version

  - by Calm Storm

  Hi, I tried doing a mvn dependency:tree and I get a tree of dependencies. My question is, My project depends on many modules which internally depends on many spring artifacts. There are a few version clashes. I want to upgrade all spring related libraries to say the latest one (2.6.x or above). What is the preferred way to do this? Should I declare all the deps spring-context, spring-support (and 10 other artifacts) in my pom.xml and point them to 2.6.x ? Is there any other better method ?

• Source Control - XCode - Visual Studio 2005/2008 / 2010

  - by Mick Walker

  My apologies if this has been asked before, I wasnt quite sure if this question should be asked on a programming forum, as it more relates to programming environment than a particular technology, so please accept my (double) appologies if I am posting this in the wrong place, my logic in this case was if it effects the code I write, then this is the place for it. At home, I do a lot of my development on a Mac Pro, I do development for the Mac, iPhone and Windows on this machine (Xcode & Visual Studio - (multiple versions installed in bootcamp, but generally I run it via Parallels)). When visiting a client, I have a similar setup, but on my MacBook Pro. What I want is a source control solution to install on the Mac Pro, that will support both XCode and multiple versions of visual studio, so that when I visit a client, I can simply grab the latest copy from source control via the MacBook Pro. Whilst visiting the client, he / she may suggest changes, and minor ones I would tend to make on site, so I need the ability to merge any modified code back into the trunk of the project / solution when I return home. At the moment, I am using no source control at all, and rely on simply coping folders and overwriting them when I return from a client- thats my 'merge'!!! I was wondering if anyone had any ideas of a source provider I could use, which would support both Windows and Mac development environments, and is cheap (free would be better).

• Get id when inserting new row using TableAdapter.Update on a file based database

  - by phq

  I have a database table with one field, called ID, being an auto increment integer. Using a TableAdapter I can read and modify existing rows as well as create new ones. However if I try to modify a newly inserted row I get an DBConcurrencyException: OleDbConnection conn = new OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=Shift.mdb;Persist Security Info=True"); ShiftDataSetTableAdapters.ShiftTableAdapter shiftTA = new ShiftDataSetTableAdapters.ShiftTableAdapter(); shiftTA.Connection = conn; ShiftDataSet.ShiftDataTable table = new ShiftDataSet.ShiftDataTable(); ShiftDataSet.ShiftRow row = table.NewShiftRow(); row.Name = "life"; table.Rows.Add(row); shiftTA.Update(row); // row.ID == -1 row.Name = "answer"; // <-- all fine up to here shiftTA.Update(row); // DBConcurrencyException: 0 rows affected Separate question, is there any static type of the NewShiftRow() method I can use so that I don't have to create table everytime I want to insert a new row. I guess the problem in the code comes from row.ID that is still -1 after the first Update() call. The Insert is successful and in the database the row has a valid value of ID. How can I get that ID so that I can continue with the second Update call? Update: IT looks like this could have been done automatically using this setting. However according to the answer on msdn social, OLEDB drivers do not support this feature. Not sure where to go from here, use something else than oledb? Update: Tried SQLCompact but discovered that it had the same limitation, it does not support multiple statements. Final question: is there any simple(single file based) database that would allow you to get the values of a inserted row.

• Feasibility of using Silverlight for web and windows client with common code base for data intensive

  - by Kabeer

  Hello. Recently in a conversation, someone suggested me to make use of Silverlight if I am targeting a web client and a windows client for the same application. This will cut down my effort for supporting the contrast in both presentation layers. Mine is a product, that will be deployed in enterprises. Both web and windows clients are desirable. With the above context, I have few queries: Is it advisable to adopt the recommended approach and whether this approach is becoming a trend? Besides, some configuration & deployment tweaking, will this significantly reduce effort on the presentation layer? Is there a possibility that my future prospects (for this product) will resist Silverlight footprint? Will I be able to make use of the ASP.Net MVC pattern? Will there be any performance implication for the web client? Will Silverlight support incremental load of controls? If my back-end includes SSRS, will I be able to harness all its front end features with Silverlight? Will I be able to support additional devices with same code base in future? Mine is a very data intensive application from both, data entry and reporting perspective. Is it advisable to use 3rd party controls (like Telerik) for improved user experience and developer productivity? Are their any professional quality open source Silverlight controls (library) available? Further, I seek information of best practices in the context I shared above.

• doublechecking: no db-wide 'unicode switch' for sql server in the foreseeable future, i.e. like Orac

  - by user72150

  Hi all, I believe I know the answer to this question, but wanted to confirm: Question Does Sql server (or will it in the foreseeable future), offer a database-wide "unicode switch" which says "store all characters in unicode (UTF-16, UCS-2, etc)", i.e. like Oracle. The Context Our application has provided "CJK" (Chinese-Japanese-Korean) support for years--using Oracle as the db store. Recently folks have been asking for the same support in sql server. We store our db schema definition in xml and generate the vendor-specific definitions (oracle, sql server) using vendor-specific xsl. We can make the change easily. The problem is for upgrades. Generated scripts would need to change the column types for 100+ columns from varchar to nvarchar, varchar(max) to nvarchar(max), etc. These changes require dropping and recreating indexes and foreign keys if the any indexes/fk's exist on the column. Non-trivial. Risky. DB-wide character encodings for us would eliminate programming changes. (I.e. we would not to change the column types from varchar to nvarchar; sql server would correctly store unicode data in varchar columns). I had thought that eventually sql server would "see the light" and allow storing unicode in varchar/clob columns. Evidently not yet. Recap So just to triple check: does mssql offer a database-wide switch for character encoding? Will it in SQL2008R3? or 2010? thanks, bill

• Selecting a Java framework for large application w/ only ONE user

  - by Bijan

  I am building a large application that will be hosted on an AWS server. I'm trying to select a web framework for assisting me with code organization, template design, and generally presentation aspects. Here are some points of consideration: Require security/login/user authentication. I may add the ability in the future to allow more than just an administrator to access the web app, but it is not a public facing website. AJAX support would be helpful. There are a couple widgets that I don't want to recreate. One is a tree object, where the user can expand/contract items in the list, can create new branches, add/edit objects. This would be better off in some dynamic view rather than all done in ugly html. Generally, this is just to provide the application with a face for control, management, and monitoring. Having an easier time adding buttons, CSS, AJAX widgets are great additions though, but not the primary purpose. I'm considering: Wicket Spring Seam GWT Stripe and the list goes on, as I'm sure you all know. I originally planned on using GWT, but then started to feel that GWT didn't cover my primary needs. I could be wrong about this, but there seems to be a lot of support for GWT AND Wicket/Spring. All of this 'getting lost in java frameworks' got me thinking outside the java realm for a framework that would suit my needs that was a clear option, like: JRuby/Rails Jython/Django Groovy/Grails Guice (just throwing this in there... I don't clearly understand the main purposes of all these frameworks. It doesn't seem like DInjection is something I need for a single purpose application) Thanks as always. This community makes Googling for esoteric programming information an order of magnitude better.

• Can GWT image sprites using ImageBundle be made to work in IE7 and IE6?

  - by aem

  I'm trying to use a ClientBundle in my GWT application to make multiple images get sent as a single file. I declare the bundle like so: public interface MyResources extends ClientBundle { public static final MyResources INSTANCE = GWT.create(MyResources.class); @Source("icon1.png") ImageResource icon1(); @Source("icon2.png") ImageResource icon2(); } This works great in Firefox and IE8, but in IE7 (and earlier) the whole sprite shows up in place of one of my original images - that is, icon1 is next to icon2 next to icon3, and so on. In IE8's developer tools using IE8-as-IE7 mode or Compatibility View, I can see that it's showing an image with a file name like 26BEFD2399A92A5DDA54277BA550C75B.cache.png, which is what I'd expect. So is there any way to make GWT image sprites work in IE7 and lower? If not, is there any way to gracefully degrade so users of other browsers get the speedup of spriting and IE7 and IE6 users get something that looks right but is slower? Edit: The Client Bundle Developer's Guide has a discussion of using ClientBundle and @sprite, and says "Support for IE6 isn't feasible in this format, because structural changes to the DOM are necessary to implement a "windowing" effect. Once it's possible to distinguish ie6 and ie7 in user.agent, we could revisit support for ie6. In the current implementation, the ie6 code won't render correctly, although is a purely cosmetic issue." Is this what's going on in my case, and is there a way to work around it? Showing all the images is "purely a cosmetic issue", but it's a pretty severe one.

• Right to Left UI in iPhone (Hebrew)

  - by Reflog

  Hello, I'm struggling in creating a RTL UI in iPhone application. The framework doesn't seem to have any support for RTL languages. The only thing is the alignment inside labels, which is nice, but it conflicts with other controls behaviour. The question is: Is there a working code for a RTL TableView? Something that would handle the disclosure buttons to be on the left, section titles to be right aligned, index view to be left aligned? As far as I understand I cannot move the index view of the tableview, i have to overlay some custom control... Any suggestions/pointers/examples? p.s. this is not a duplication of this question: http://stackoverflow.com/questions/1677988/right-to-left-alignment-for-uitableview since what I am looking for is a deeper customization, not just a new type of CellView. (Update: Mar 10) For now - I've removed support for indexView from the tableView at all, implemented the cells as custom views by myself (with disclosure buttons on the left), and customized the header/footer of the table as well. the only thing that is left is the Index View. Thanks in advance!

• PHP and C# communication on IIS7 (to generate dynamic PDF)

  - by David Murdoch

  Background: I couldn't find any decent free HTML to PDF conversion utilities in C#. There are 100s of them for PHP with extensive documentation, support, and CSS support. So I am using html2ps and html2pdf (php). I have PHP 5.2 installed on IIS7 and its working beautifully to create PDFs. I have the following in getPDF.aspx <!-- Output the header --> <DM:header runat="server" ID="header" /> <asp:Placeholder id="content" runat="server" /> <!-- Output the footer --> <DM:footer runat="server" ID="footer" /> and in getPDF.aspx.cs: protected void Page_Load(object sender, EventArgs e){ // AddContentControl simples adds a controls to the content Placeholder. AddContentControl("controls/page1.ascx"); AddContentControl("controls/page2.ascx"); AddContentControl("controls/page3.ascx"); } and in generatePDF.php: <?php /* ... includes and stuff here ... */ $data = "THE HTML GOES HERE!"; // creates the PDF from the $data and Outputs the created file. convert_to_pdf($data); ?> -- getPDF.aspx works perfectly...except the output is HTML. So how can I get getPDF.aspx to output its HTML as PDF generated by generatePDF.php?

• What's the strategy to implement a "knowledge base" in my company. [closed]

  - by Oscar Reyes

  In my current work we think we can get benefit from having a knowledge base, so the next time someone has a question/problem etc, that base can be consulted and an answer will show up. Also, it will reduce the risk from having people leaving the company with the knowledge and we would have to start all over again. My question is, what strategy can we follow to implement/buy/get/build/etc this knowledge base? Are there software ready for this? Would it be better to have something build by ourselves ( we have some programmers ) This is an small company ( < 30 ) and the base should be accessible from outside the office ( when the employees are with the customer etc.) so I guess a webapp is in order.

• Versioning friendly, extendible binary file format

  - by Bas Bossink

  In the project I'm currently working on there is a need to save a sizable data structure to disk (edit: think dozens of MB's). Being an optimist, I thought that there must be a standard solution for such a problem; however, up to now I haven't found a solution that satisfies the following requirements: .NET 2.0 support, preferably with a FOSS implementation Version friendly (this should be interpreted as: reading an old version of the format should be relatively simple if the changes in the underlying data structure are simple, say adding/dropping fields) Ability to do some form of random access where part of the data can be extended after initial creation (think of this as extending intermediate results) Space and time efficient (XML has been excluded as option given this requirement) Options considered so far: Protocol Buffers: was turned down by verdict of the documentation about Large Data Sets - since this comment suggested adding another layer on top, this would call for additional complexity which I wish to have handled by the file format itself. HDF5,EXI: do not seem to have .net implementations SQLite/SQL Server Compact edition: the data structure at hand would result in a pretty complex table structure that seems too heavyweight for the intended use BSON: does not appear to support requirement 3. Fast Infoset: only seems to have paid .NET implementations. Any recommendations or pointers are greatly appreciated. Furthermore if you believe any of the information above is not true, please provide pointers/examples to prove me wrong.

• Toshiba eStudio 281c turn off snmp in driver.

  - by Matt

  I have a customer with an eStudio 281c colour copier/printer and I'm having an issue with terminal services. Basically, the driver has the ability to query the printer for its configuration over snmp. I've set it to manual rather than auto so it's effectively switched off. Trouble is, when logging into terminal services it's still trying to communicate with the printer. This is an issue because when it fails it then defaults to being a different printer model with a different tray configuration. Users can still print but the settings are wrong. Any ideas?

• Are there website monitoring services that can monitor HTTP file download times?

  - by Mark

  The software company I work for would like to monitor how long it takes to download their installers (hosted in several locations and about 30-100mb each) from various countries around the world. I am aware of website monitoring services like Pingdom and Site24x7, and have contacted their customer services, but neither have the facility to monitor download times of such large files via HTTP. For various reasons, we are not able to rely on weblogs. Does anyone know of any third-party services that could help us? Many thanks.

• Use JAXB unmarshalling in Weblogic Server

  - by Leo

  Especifications: - Server: Weblogic 9.2 fixed by customer. - Webservices defined by wsdl and xsd files fixed by customer; not modifications allowed. Hi, In the project we need to develope a mail system. This must do common work with the webservice. We create a Bean who recieves an auto-generated class from non-root xsd element (not wsdl); this bean do this common work. The mail system recieves a xml with elements defined in xsd file and we need to drop this elements info to wsdlc generated classes. With this objects we can use this common bean. Is not possible to redirect the mail request to the webservice. We've looking for the code to do this with WL9.2 resources but we don't found anything. At the moment we've tried to use JAXB for this unmarshalling: JAXBContext c = JAXBContext.newInstance(new Class[]{WasteDCSType.class}); Unmarshaller u = c.createUnmarshaller(); WasteDCSType w = u.unmarshal(waste, WasteDCSType.class).getValue(); waste variable is an DOM Element object. It isn't the root element 'cause the root isn't included in XSD First we needed to add no-arg constructor in some autogenerated classes. No problem, we solved this and finally we unmarshalled the xml without error Exceptions. But we had problems with the attributes. The unmarshalling didn't set attributes; none of them in any class, not simple attributes, not large or short enumeration attributes. No problem with xml elements of any type. We can't create the unmarshaller from "context string" (the package name) 'cause not ObjectFactory has been create by wsldc. If we set the schema no element descriptions are founded and unmarshall crashes. This is the build content: <taskdef name="jwsc" classname="weblogic.wsee.tools.anttasks.JwscTask" /> <taskdef name="wsdlc" classname="weblogic.wsee.tools.anttasks.WsdlcTask"/> <target name="generate-from-wsdl"> <wsdlc srcWsdl="${src.dir}/wsdls/e3s-environmentalMasterData.wsdl" destJwsDir="${src.dir}/webservices" destImplDir="${src.dir}/webservices" packageName="org.arc.eterws.generated" /> <wsdlc srcWsdl="${src.dir}/wsdls/e3s-waste.wsdl" destJwsDir="${src.dir}/webservices" destImplDir="${src.dir}/webservices" packageName="org.arc.eterws.generated" /> </target> <target name="webservices" description=""> <jwsc srcdir="${src.dir}/webservices" destdir="${dest.dir}" classpathref="wspath"> <module contextPath="E3S" name="webservices"> <jws file="org/arc/eterws/impl/IE3SEnvironmentalMasterDataImpl.java" compiledWsdl="${src.dir}/webservices/e3s-environmentalMasterData_wsdl.jar"/> <jws file="org/arc/eterws/impl/Ie3SWasteImpl.java" compiledWsdl="${src.dir}/webservices/e3s-waste_wsdl.jar"/> <descriptor file="${src.dir}/webservices/META-INF/web.xml"/> </module> </jwsc> </target> My questions are: How Weblogic "unmarshall" the xml with the JAX-RPC tech and can we do the same with a xsd element? How can we do this if yes? If not, Exists any not complex solution to this problem? If not, must we use XMLBean tech. or regenerate the XSD with JAXB tech.? What is the best solution? NOTE: There are not one single xsd but a complex xsd structure in fact.

• visual studio 2008 vs 2010 Pro unmanaged code

  Hi, I'm a C++ programmer, I use Visual Studio 2008 Professional, only unmanaged code. I'm thinking of buying VS 2010 Pro. I'm confused, I don't know what are differences between those two. I know that, in plus, it has tr1 included. When I started using 2008 edition I was very pleased to see f.e. unit testing support but all new features are only for managed code. The C++ debugger in 2008 is very good, better than 2003 edition one. I would't like to buy a new tool and discover that I gained nothing and lost some functionality ( because f.e. something was moved to higher version). Once upon a time I switched from very good VS6 to VS 2003.Net and imagine what, after some time I discovered that Pro has no support for code optimalization. It is wonderful how Microsoft makes money. I wouldn't like to experience something like that again. What do you think, what can you recommended?

• WinForms data binding with a Save button?

  - by Mat

  How is data binding in C# WinForms supposed to work when you have a Save button? I don't want the data updated until I press Save! I have two forms (list and detail) backed by a BindingList<T> collection and my custom object from that collection, respectively. I can bind each form to the list or object appropriately. However, any changes made in the detail form are immediately reflected in the list form - I don't want to save the changes and update the details shown in the list until the Save button is pressed. Is data binding designed to support this? Is there a common pattern for doing so? Whichever way I look at it, binding doesn't seem to be able to support this scenario. I've considered the following: Pass a clone of the object to the detail form, but then I have to reconcile the changes on Save - changes may have been made to the copy in the list in the meantime. Implementing IEditableObject and calling EndEdit on save almost works as I can prevent the list being notified of the changes made until Save is pressed, but if something else causes a refresh the list is updated with the interim data. I'm currently left with dispensing with data binding in my detail view, and doing it all manually. Which is rather annoying.

• Detecting browser capabilities and selective events for mouse and touch

  - by skidding

  I started using touch events for a while now, but I just stumbled upon quite a problem. Until now, I checked if touch capabilities are supported, and applied selective events based on that. Like this: if(document.ontouchmove === undefined){ //apply mouse events }else{ //apply touch events } However, my scripts stopped working in Chrome5 (which is currently beta) on my computer. I researched it a bit, and as I expected, in Chrome5 (as opposed to older Chrome, Firefox, IE, etc.) document.ontouchmove is no longer undefined but null. At first I wanted to submit a bug report, but then I realized: There are devices that have both mouse and touch capabilities, so that might be natural, maybe Chrome now defines it because my OS might support both types of events. So the solutions seems easy: Apply BOTH event types. Right? Well the problem now take place on mobile. In order to be backward compatible and support scripts that only use mouse events, mobile browsers might try to fire them as well (on touch). So then with both mouse and touch events set, a certain handler might be called twice every time. What is the way to approach this? Is there a better way to check and apply selective events, or must I ignore the problems that might occur if browsers fire both touch and mouse events at times?

• Formula parsing / evaluation routine or library with generic DLookup functionality

  - by tbone

  I am writing a .Net application where I must support user-defined formulas that can perform basic mathematics, as well as accessing data from any arbitrary table in the database. I have the math part working, using JScript Eval(). What I haven't decided on is what a nice way is to do the generic table lookups. For example, I may have a formula something like: Column: BonusAmount Formula: {CurrentSalary} * 1.5 * {[SystemSettings][Value][SettingName=CorpBonus AND Year={Year}]} So, in this example I would replace {xxx} and {Year} with the value of Column xxx from the current table, and I would replace the second part with the value of (select Value from SystemSettings WHERE SettingName='CorpBonus' AND Year=2008) So, basically, I am looking for something very much like the MS Access DLookup function: DLookup ( expression, domain, [criteria] ) DLookup("[UnitPrice]", "Order Details", "OrderID = 10248") But, I also need to overall parsing routine that can tell whether to just look up in the current row, or to look into another table. Would also be nice to support aggregate functions (ie: DAvg, DMax, etc), as well as all the weird edge cases handled. So I wonder if anyone knows of any sort of an existing library, or has a nice routine that can handle this formula parsing and database lookup / aggregate function resolution requirements.

• Setting Access-Control-Allow-Origin in Dreamhost possible?

  - by Kaushik Gopal

  Just wanted a confirmation for this: Firefox currently doesn't play well for picking custom fonts through a sub-domain via the font-face tag. Other browsers do this without any problems. A little research showed up saying that i am required to set the Access-Control-Allow-Origin as is shown in the link here: http://pastie.org/653265 Essentially i have my blog at kaushikgopal.com/blog and i was trying to access fonts that within this blog that are available at font.kaushikgopal.com. I tried changing the same in my .htaccess file but couldn't resolve the issue.(I placed a .htaccess file within the font sub-domain folder and directly pasted code from the above pastie link). I submitted a ticket to dreamhost asking for assistance and they were helpful in clearly stating "We do not support Access-Control-Allow-Origin on shared hosting servers". So i didn't go the sub-domain route for fonts. But i'm a little curious, has anyone tried this (with a dreamhost hosting account would be helpful)? Just want to confirm what the tech-support guy suggested is accurate and there's no other way. Thanks. Another nice link clearly stating the problem : http://www.stevesouders.com/tests/font-face/xdomain.php
