• Glassfish 3: How do I get and use a developers build so I can navigate a stack trace including Glas

  - by Thorbjørn Ravn Andersen

  I am migrating a JSF 1.1 application to JEE 6 Web profile, and doing it in steps. I am in the process of moving from JSP with JSF 1.1 to Facelets under JSF 1.2 using the jsf-facelets.jar for JSF 1.2, and received an "interesting" stack trace when trying to lookup a key in a Map using a "{Bean.foo.map.key}" where the stacktrace complained about "key" not being a valid integer. (After code introspection I am workarounding it using a number as the key). That bug is not what this question is about. In such a situation it is essential to be able to navigate the source of every line in the stack trace. In Eclipse I normally attach a source jar to every jar on the build path, but in this particular case the Glassfish server adapter creates a library automatically containing the jars. Also there is to my knowledge no debug build of Glassfish where sources are included in the bundle. Glassfish is a non-trivial Maven project, and a bit picky too. I am not very familiar with maven, but have managed to checkout the code from Subversion and build it for the 3.0 tag according to http://wiki.glassfish.java.net/Wiki.jsp?page=V3FullBuildInstructions#section-V3FullBuildInstructions-CheckoutTheWorkspace - it appears to be the code corresponding to the official released 3.0 version. After finishing the "mvn -U install" part, I have then tried to create Eclipse projects by first using "mvn -DdownloadSources=true eclipse:eclipse" and then import them in Eclipse JEE 3.5.2 and specifying the M2_REPO variable but many of the projects still have compilation errors, and I cannot locate any instructions from Oracle about how to do this. I'd appreciate some help in just getting a functional IDE workspace reflecting the 3.0 version of Glassfish. I have Eclipse 3.5.2, Netbeans 6.8 and 6.9 beta, and IntelliJ IDEA 9, and Linux/Windows/OS X do do it on.

• Is there an easy way to replace a deprecated method call in Xcode?

  - by Alex Basson

  So iOS 6 deprecates presentModalViewController:animated: and dismissModalViewControllerAnimated:, and it replaces them with presentViewController:animated:completion: and dismissViewControllerAnimated:completion:, respectively. I suppose I could use find-replace to update my app, although it would be awkward with the present* methods, since the controller to be presented is different every time. I know I could handle that situation with a regex, but I don't feel comfortable enough with regex to try using it with my 1000+-files-big app. So I'm wondering: Does Xcode have some magic "update deprecated methods" command or something? I mean, I've described my particular situation above, but in general, deprecations come around with every OS release. Is there a better way to update an app than simply to use find-replace?

• Testing the program in different OS

  - by Alex Farber

  I want to test my program by installing it in different OS versions. My development computer is Ubuntu. What other Linux versions can I test by installing them inside VirtualBox and running my program there? Though it is not critical for me right now, I want to try something different and see what happens. Also, what is the chance that the program running in Linux will work in the Unix OS? The program is not open source, I can distribute only pre-built binaries.

• Keyboard shortcut to Un/Comment out code in Mathematica 7?

  - by dbjohn

  A keyboard shortcut to comment/uncomment out a piece of code is common in other programming IDE's for languages like Java, .Net. I find it a very useful technique when experimenting through trial and error to temporarily comment out and uncomment lines, words and parts of the code to find out what is and isn't working. I cannot find any such keyboard shortcut on the Mathematica front end in version 7. I know that it is possible to comment out code by selecting the code, right mouse click and select Un/Comment from the menu that appears but this is too slow while coding. I tried to access this using the menu key Menu on the keyboard but Mathematica frontend doesn't respond to or recognise this key unlike other applications, this could have allowed a key combination for commenting. Can someone else verify that this isn't unique to my machine and that the key isn't recognised by mathematica. I looked at this question and looked in the KeyEventTranslations.tr file but I don't think there is any way to create a shortcut to do this(?). Should I just live with it? Any other suggestions? (I have seen there is an Emacs version of mathematica, I have never tried Emacs or this Mma version and imagine that it would have this ability but would prefer not to go to the trouble and uncertainty of installing it. Also I would guess that the Wolfram Workbench could do this, but that may not be worth the investment just for this.)

• C# using the "this" keyword in this situation?

  - by Alex

  Hi, I've completed a OOP course assignment where I design and code a Complex Number class. For extra credit, I can do the following: Add two complex numbers. The function will take one complex number object as a parameter and return a complex number object. When adding two complex numbers, the real part of the calling object is added to the real part of the complex number object passed as a parameter, and the imaginary part of the calling object is added to the imaginary part of the complex number object passed as a parameter. Subtract two complex numbers. The function will take one complex number object as a parameter and return a complex number object. When subtracting two complex numbers, the real part of the complex number object passed as a parameter is subtracted from the real part of the calling object, and the imaginary part of the complex number object passed as a parameter is subtracted from the imaginary part of the calling object. I have coded this up, and I used the this keyword to denote the current instance of the class, the code for my add method is below, and my subtract method looks similar: public ComplexNumber Add(ComplexNumber c) { double realPartAdder = c.GetRealPart(); double complexPartAdder = c.GetComplexPart(); double realPartCaller = this.GetRealPart(); double complexPartCaller = this.GetComplexPart(); double finalRealPart = realPartCaller + realPartAdder; double finalComplexPart = complexPartCaller + complexPartAdder; ComplexNumber summedComplex = new ComplexNumber(finalRealPart, finalComplexPart); return summedComplex; } My question is: Did I do this correctly and with good style? (using the this keyword)?

• Help with jQuery Validation plugin and a form that uses 'panels'

  - by alex

  I have a form that works in 'sections' that I will refer to as 'panels'. By default, the form is listed out on the page, one panel after the other. However, with JavaScript, it puts the panels into one panel viewer, and displays them one after the other (with prev/next buttons). Example Form Workflow Panel 1: User Details - Panel 2: User Location - Panel 3: User Info - Panel 4: Confirm Details I am using the jQuery Validation plugin. My problem is, I have set up all the rules for all the inputs in the first 3 panels, and I'd like to be able to only validate a subset of them per panel. Example, when pushing 'next panel' after completing name & email (in the 1st, user details panel), I'd like to do a validation only on that panel first, and then get a boolean response (if the 1st panel validated), and if true, then proceed to the next panel. I've played around with a bit of the config, but unfortunately could not get it to work as I wanted. This is my first project with this plugin so I'm quite new to it! Is there a way to add rules dynamically to the plugin? i.e. not on $('form').validate(options) ? What I'd like to do, is call the validate() on the form, with all the error messages, and then on the 'next panel' code, do a switch case to determine which rules to add, and then call a validate() myself.

• Testing in Scrum

  - by alex

  In Scrum it's a good idea to test frequently when iteration is finished at customer. But the question is what kind of test should I use when some of the prototype is done with customer? In my knowledge Acceptance test is ok when all the iteration is done - but not some part of it. Examples for the test plan would be helpful

• Limit URL Parameter Length in Web.Config

  - by Alex

  Is it possible to add some kind of restriction to the web.config to limit URL parameter length? I want to prevent people at the earliest possible point from submitting too large URL parameters so the server doesn't get taxed more than necessary in the event that somebody tries to "attack" it with large invalid URL parameters.

• Qt/PyQt dialog with togglable fullscreen mode - problem on Windows

  - by Guard

  I have a dialog created in PyQt. It's purpose and functionality don't matter. The init is: class MyDialog(QWidget, ui_module.Ui_Dialog): def __init__(self, parent=None): super(MyDialog, self).__init__(parent) self.setupUi(self) self.installEventFilter(self) self.setWindowFlags(Qt.Dialog | Qt.WindowTitleHint) self.showMaximized() Then I have event filtering method: def eventFilter(self, obj, event): if event.type() == QEvent.KeyPress: key = event.key() if key == Qt.Key_F11: if self.isFullScreen(): self.setWindowFlags(self._flags) if self._state == 'm': self.showMaximized() else: self.showNormal() self.setGeometry(self._geometry) else: self._state = 'm' if self.isMaximized() else 'n' self._flags = self.windowFlags() self._geometry = self.geometry() self.setWindowFlags(Qt.Tool | Qt.FramelessWindowHint) self.showFullScreen() return True elif key == Qt.Key_Escape: self.close() return QWidget.eventFilter(self, obj, event) As can be seen, Esc is used for dialog hiding, and F11 is used for toggling full-screen. In addition, if the user changed the dialog mode from the initial maximized to normal and possibly moved the dialog, it's state and position are restored after exiting the full-screen. Finally, the dialog is created on the MainWindow action triggered: d = MyDialog(self) d.show() It works fine on Linux (Ubuntu Lucid), but quite strange on Windows 7: if I go to the full-screen from the maximized mode, I can't exit full-screen (on F11 dialog disappears and appears in full-screen mode again). If I change the dialog's mode to Normal (by double-clicking its title), then go to full-screen and then return back, the dialog is shown in the normal mode, in the correct position, but without the title line. Most probably the reason for both cases is the same - the setWindowFlags doesn't work. But why? Is it also possible that it is the bug in the recent PyQt version? On Ubuntu I have 4.6.x from apt, and on Windows - the latest installer from the riverbank site.

• Google Maps custom marker - can the iframe accept one like the static maps?

  - by alex

  I was reading the static maps API, and it says you can include a custom marker in the GET params. You simply link to an image file. I now have a second Google Map within an iframe, and was wondering if you can attach custom markers via the GET params to it? Here is the src attribute of the iframe currently. http://maps.google.com/maps?f=q&source=s_q&hl=en&geocode=&q=111+Fake+Street+Noosaville+Queensland+Australia&ie=UTF8&output=embed I can't seem to find the documentation on how to do this, if possible. Is this possible?

• SQL/Schema comparison and upgrade

  - by Workshop Alex

  I have a simple situation. A large organisation is using several different versions of some (desktop) application and each version has it's own database structure. There are about 200 offices and each office will have it's own version, which can be one of 7 different ones. The company wants to upgrade all applications to the latest versions, which will be version 8. The problem is that they don't have a separate database for each version. Nor do they have a separate database for each office. They have one single database which is handled by a dedicated server, thus keeping things like management and backups easier. Every office has it's own database schema and within the schema there's the whole database structure for their specific application version. As a result, I'm dealing with 200 different schema's which need to be upgraded, each with 7 possible versions. Fortunately, every schema knows the proper version so checking the version isn't difficult. But my problem is that I need to create upgrade scripts which can upgrade from version 1 to version 2 to version 3 to etc... Basically, all schema's need to be bumped up one version until they're all version 8. Writing the code that will do this is no problem. the challenge is how to create the upgrade script from one version to the other? Preferably with some automated tool. I've examined RedGate's SQL Compare and Altova's DatabaseSpy but they're not practical. Altova is way too slow. RedGate requires too much processing afterwards, since the generated SQL Script still has a few errors and it refers to the schema name. Furthermore, the code needs to become part of a stored procedure and the code generated by RedGate doesn't really fit inside a single procedure. (Plus, it's doing too much transaction-handling, while I need everything within a single transaction. I have been considering using another SQL Comparison tool but it seems to me that my case is just too different from what standard tools can deliver. So I'm going to write my own comparison tool. To do this, I'll be using ADOX with Delphi to read the catalogues for every schema version in the database, then use this to write the SQL Statements that will need to upgrade these schema's to their next version. (Comparing 1 with 2, 2 with 3, 3 with 4, etc.) I'm not unfamiliar with generating SQL-Script-Generators so I don't expect too many problems. And I'll only be upgrading the table structures, not any of the other database objects. So, does anyone have some good tips and tricks to apply when doing this kind of comparisons? Things to be aware of? Practical tips to increase speed?

• MySQL LEFT JOIN error

  - by Alex

  Hello, I've got some SQL that used to work with an older MySQL version, but after upgrading to a newer MySQL 5 version, I'm getting an error. Here's the SQL: SELECT portfolio.*, projects.*, types.* FROM projects, types LEFT JOIN portfolio ON portfolio.pfProjectID = projects.projectID WHERE projects.projectType = types.typeID AND types.typeID = #URL.a# ORDER BY types.typeSort, projects.projectPriority ASC and the new error I'm receiving: Unknown column 'projects.projectID' in 'on clause' How can I convert this to compatible SQL for the newer MySQL version? Thanks very much!

• Setting minOccurs="0" (required) on web service parameters of type int

  - by Alex Angas

  I have an ASP.NET 2.0 web method with the following signature: [WebMethod] public QueryResult[] GetListData( string url, string list, string query, int noOfItems, string titleField) I'm running the disco.exe tool to generate .wsdl and .disco files from this web service for use in SharePoint. The following WSDL for the parameters is being generated: <s:element minOccurs="0" maxOccurs="1" name="url" type="s:string" /> <s:element minOccurs="0" maxOccurs="1" name="list" type="s:string" /> <s:element minOccurs="0" maxOccurs="1" name="query" type="s:string" /> <s:element minOccurs="1" maxOccurs="1" name="noOfItems" type="s:int" /> <s:element minOccurs="0" maxOccurs="1" name="titleField" type="s:string" /> Why does the int parameter have minOccurs set to 1 instead of 0 and how do I change it? I've tried using [XmlElementAttribute(IsNullable=false)] in the parameter declaration without success.

• Using data from a dataset in styles with Mapnik

  - by Alex King

  I've setup Mapnik to connect to a PostGIS database, and display geometry. I'd like to have a column in my database called opacity, and use it as the opacity for that row of geometry when Mapnik renders it. So far, I've only found information on how to display text from the database, and how to use filters to display different styles when database values are within parameters. Nothing about how to use the values directly inside of a style or layer though - is this possible?

• Strange behavior of DDD debugger in Ubuntu

  - by Alex Farber

  I installed DDD debugger in Ubuntu and trying to work with it. It looks like DDD UI doesn't work properly with Ubuntu desktop environment. Edit boxes are almost unusable: sometimes they accept keyboard input, most of times input is ignored. Internal resizing panes are not working. Is there some way to get DDD UI working properly? The same behavior is in Ubuntu 9.10 32 bit, and 10.4 64 bit, so this is not Ubuntu version issue.

• How to build a simulation of a login hardware token in .Net

  - by Michel

  Hi, i have a hardware token for remote login to some citrix environment. When i click the button on the device, i get an id and i can use that to login to the citrix farm. I can click the button as much as i like, and every time a new code gets generated, and they all work. Now i want to secure my private website likewise, but not with the hardware token, but with a 'token app' on my phone. So i run an app on my phone, generate a key, and use that to (partly) authenticate myself on the server. But here's the point: i don't know how it works! How can i generate 1, 2 or 100 keys at one time which i can see (on the server) are all valid, but without the server and the phone app having contact (the hardware token also is an 'offline' solution). Can you help me with a hint how i would do this? This is what i thought of so far: the phone app and the server app know (hardcoded) the same encryption key. The phone app encrypts the current time. The server app decrypts the string to the current time and if the diff between that time and the actual server time is less than 10 minutes it's an ok. Difficult for other users to fake a key, but encryption gives such nasty strings to enter, and the hardware token gives me nice things like 'H554TU8' And this is probably not how the real hardware token works, because the server and the phone app must 'know' the same encryption key.

• Are CMAttitude and CATransform3D related by rotational matrices?

  - by Alex Stone

  I'm looking at the core motion class CMAttitude, it can express the device's orientation as a 3x3 rotational matrix. At the same time I've taken a look at the CATransform3D, which encapsulates the view's attitude, as well as scaling. The CATransform3D is a 4x4 matrix. I've seen that the OpenGL rotational matrix is 4x4 and is simply 0001 padded in the 4th row and column. I'm wandering if the CMAttitude's rotational matrix is related to CATransform's matrix? Can I use the device's rotation in space obtained via a rotational matrix to transform a UIView using CATransform3D? My intention is to let the user move the phone and apply the same transform to a UIView on the screen. Bonus question: if they are related, how do I transform a CMAttitude's rotational matrix to CATransform3D?

• Ruby TypeErrors involving `expected Data`

  - by Kenny Peng

  I've ran into situations where I have gotten these expected Data errors before, but they have always pointed to ActiveRecord not playing well with other libraries in the past. This piece of code: def load(kv_block, debug=false) # Converts a string block to a Hash using split kv_map = StringUtils.kv_array_to_hash(kv_block) # Loop through each key, value kv_map.each do |mem,val| # Format the member from camel case to underscore member = mem.camel_to_underscore() # If the object includes a method to set the key (i.e. the key # is a member of self), invoke the method, setting the value of # the member) if self.methods.include?(member.to_set_method_name()) then # Exception thrown here self.send(member.to_set_method_name(), val) # Else, check for the same case, this time for an instance variable elsif self.instance_variable_defined?(member.to_instance_var_name()) self.instance_variable_set(member.to_instance_var_name(), val) # Else, complain that the object doesn't understand the key with # respect to its class definition. else raise ArgumentError, "I don't know what to do with #{member}. #{self.class} does not have a member or function called #{member}" end end end produces the error wrong argument type #<Class:0x11a02088> (expected Data) (TypeError) in the each loop on the first if test. I've inspected a post-mortem debugging instance using rdebug, and running that line manually, it works without a hitch. Has anyone seen this error before and what's been your solution to it? I used to think it was ActiveRecord and other gems stomping on each other's definitions, but I removed any references to ActiveRecord and this still occurs.

• VSS keep resetting working folder a the root of the C: drive

  - by Alex

  I have noticed several times (that is it does not happens all the time, but occurs regulary) that VSS has forgoten my working folder settings and re-set it to be a root of the C: drive. It is very annoying to find out that some of the files you have checked out and been working on are not in the same folder where you expect them to be (and it also pollutes the drive with a C:\SubProject1, C:\SubProject2 folders instead of keeping them all inside of C:\Work). Any recomendation to prevent VSS from doing this again and again. And yes, please, don't recomment switching to SVN, CVS, TFS etc - there are the rules I can't change.

• Unicode and PHP - am I doing something wrong?

  - by alex

  I'm using Kohana 3, which has full support for Unicode. I have this as the first child of my <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> The Unicode character I am inserting into is é as in Café. However, I am getting the triangle with a ? (as in could not decode character). As far as I can tell in my own code, I am not doing any string manipulation on the text. In fact, I have placed the accent straight into a view's PHP file and it is still not working. I copied the character from this page: http://www.fileformat.info/info/unicode/char/00e9/index.htm I've only just started examining PHP's Unicode limitations, so I could be doing something horribly wrong. So, how do I display this character? Do I need to resort to the HTML entity?

• one table is shared between several websites

  - by sami

  I have a static table that's shared by several websites. By static, I mean that the data is read but never updated by the websites. Currently, all websites are served from the same server but that may change. I want to minimize the need for creating/maintaining this table for each of the websites, so I thought about turning it to an xml file that's stored in a shared library that all websites have access to. The problem is I use an ORM and use forign key constraints to ensure integrity of the ids used from that table, so by removing that table out of the MySQL database into an XML file, will this affect the integrity of the ids coming from that table? My table looks like this <table name="entry"> <column name="id" type="INTEGER" primaryKey="true" autoIncrement="true" /> <column name="title" type="VARCHAR" size="500" required="true" /> </table> and I use it as a foreign key in other tables <table name="refer"> <column name="id" type="INTEGER" primaryKey="true" autoIncrement="true" /> <column name="linkto" type="INTEGER"/> <foreign-key foreignTable="entry"> <reference local="linkto" foreign="id" /> </foreign-key> </table> So I'm wondering if I remove that table out of the database, is there a way to retain that referential integrity? And of course are these any other efficient ways to do the same thing? I just don't want to have to repeat that table for several websites.
