• Building a Java EE app on Mac OS X Snow Leopard for Glassfish 3

  - by Simon

  I'm having a bit of a problem building a Java Enterprise Edition web application on Mac OS X 10.6.2 using Ant 1.7.1, Glassfish v3 and Java EE 6. The problem is that the build process does not find the Java EE libraries which fair enough as I don't think Apple supply them with the default Java installation but I know they exist in the Glassfish distribution. Which jars are the correct ones to build against (I'm assuming javaee.jar is a general jar which references all the other needed jars) and what should I be putting in my ant build.xml file? Any help is very much appreciated.

• regex , php, preg_match

  - by Michael

  I'm trying to extract the mileage value from different ebay pages but I'm stuck as there seem to be too many patterns because the pages are a bit different . Therefore I would like to know if you can help me with a better pattern . Some examples of items are the following : http://cgi.ebay.com/ebaymotors/1971-Chevy-C10-Shortbed-Truck-/250647101696?cmd=ViewItem&pt=US_Cars_Trucks&hash=item3a5bbb4100 http://cgi.ebay.com/ebaymotors/1987-HANDICAP-LEISURE-VAN-W-WHEEL-CHAIR-LIFT-/250647101712?cmd=ViewItem&pt=US_Cars_Trucks&hash=item3a5bbb4110 http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItemNext&item=250647101696 Please see the patterns at the following link (I still cannot figure it out how to escape the html here http://pastebin.com/zk4HAY3T However they are not enough many as it seems there are still new patters....

• Full page reload on Post/Redirect/Get ignoring cache control

  - by Kristof Neirynck

  I have a page that loads a lot of images, css and javascript. I've added a far future Expires header and set Cache-Control to public on these external dependencies so they should be cached. But every time I do a Post/Redirect/Get chrome tries to load these again. This behavior is very similar to reloading the page. I've added ETags and handle the If-None-Match header which helps a bit, but it still generates too many useless requests. How do I tell chrome and safari to get the files from cache? chrome NOK safari NOK firefox OK ie OK Also see Full page reload on Post/Redirect/Get ignoring cache control on the google support forum.

• jquery slider breaks on page refrsh

  - by Nik

  I have a jquery content slider on a site I'm developing. I am having a strange problem that seems to be across all browsers and that is the slider slides the wrong distance if the page is refreshed via the refresh button. To re-create the problem please follow these steps - click this link http://www.aus-media.com/dev/site_BYS/index.html then click on the 'About Bikram Yoga' menu item at the bottom. Click on the 'more' and 'back' tabs on this page and you will notice it works fine. Then refresh the page by clicking the refresh button and try the more and back buttons again. I'm a bit of a javascript newby so I'm lost to why it's doing this. Any help would be great. Thanks Nik

• Problem retrieving Hostaddress from Win32_TCPIPPrinterPort

  - by Anthony

  I'm running into an odd issue retrieving printer port addresses. When I get all the entries in Win32_TCPIPPrinterPort, the HostAddress field (which should have the IP address) is usually blank/null, only the port name has a value. To make it a bit stranger, if a particular port is not in use by any printer, THEN the HostAddress will have the the proper value. The C# code is simple, and results in something like this; IP_192.168.1.100, printerportxyz, richTextBox1.Clear(); ManagementObjectSearcher portSearcher = new ManagementObjectSearcher("root\\CIMV2", "SELECT * FROM Win32_TCPIPPrinterPort"); foreach (ManagementObject port in portSearcher.Get()) { richTextBox1.AppendText( String.Format("Name: {0} HostAddress: {1}", port["Name"], port["HostAddress"]) ); } I also tried the same thing in WSH/VBS, and saw the same behavior.

• Any Win32 APIs to get the screenshots?

  - by Microkernel

  Hi all, I am writing an app, which needs to take the screen shots automatically (just like pressing PrintScreen button). So please suggest me how to get this done. A raw 24 bit BMP image would suffice. PLEASE NOTE: My app is in C, so any win32 APIs that can be called from my code is what I am looking for. (Sometimes back I had got an example code from codeproject which used to get the screen shots but the mouse pointer user to blink when the screen shot is taken. As multiple shots are taken this looks irritating to the user, so I don't want the mouse pointer to blink!) Regards, Chethan KR

• Frequent Netbeans freezes

  - by danilo

  I'm using Netbeans 6.8 for PHP projects located on network drives in a Windows network. Frequently, the IDE gets really slow (like a temporary freeze) to a point where it's totally unusable. At first it seems like a total crash, but after some time (might be sevaral minutes) the IDE works again as before. This happens with Netbeans 6.7 as well as 6.8 on my Windows XP 32-bit installation. I'm using Java 1.6.0_13. This is a fresh Netbeans installation, so it can't have to do with too many temp files. I assume it has to do with the frequent code checks that Netbeans does. It's probably not very fast when doing this over the network connection. But it can't be that this feature renders the IDE useless... This thread deals with the same issue http://forums.netbeans.org/viewtopic.php?t=5548. Does anyone know a solution to this problem?

• Ideablade Update

  Hi, I'm using IdeaBlade version 3.6. I noticed the following generated SQL update query : (@P1 nchar(32),@P2 nvarchar(32),@P3 nvarchar(512),@P4 nchar(32),@P5 int,@P6 nvarchar(32),@P7 int,@P8 datetime,@P9 datetime,@P10 datetime,@P11 int,@P12 datetime,@P13 int,@P14 int,@P15 int,@P16 nvarchar(32),@P17 nvarchar(128),@P18 nvarchar(32),@P19 nvarchar(32),@P20 datetime,@P21 datetime,@P22 bit,@P23 nvarchar(32),@P24 nvarchar(64),@P25 nchar(32))update "dbo"."GSS_Documents" set "DocumentID"=@P1,"FileName"=@P2,"FilePath"=@P3,"BusinessOfficeID"=@P4,"Pages"=@P5,"FileSize"=@P6,"DocumentType"=@P7,"DateCreated"=@P8,"EffectiveDateCreated"=@P9,"DateProcessed"=@P10,"ProcessorID"=@P11,"DateReviewed"=@P12,"ReviewerID"=@P13,"WorkflowStatus"=@P14,"ApprovalStatus"=@P15,"AccountNumber"=@P16,"AccountName"=@P17,"SerialNumber"=@P18,"TransactionID"=@P19,"CriticalDate"=@P20,"EmergencyDate"=@P21,"GenerateSMSAlert"=@P22,"CustomerPhoneNumber"=@P23,"CustomerEmailAddress"=@P24 where "DocumentID"=@P25 Problem is DocumentID is the primary key.

• jQuery live() ... have to click twice to activate links?

  - by neezer

  I have the following bit of code, simply: $(function() { $('a.add-photos-link').live('click', function(e) { $(this).colorbox({ overlayClose: false, onComplete: function() { $('#add_photos').submit(function(e) { // more stuff to do e.preventDefault(); }); } }); e.preventDefault(); }); }); However, this only seems to work after single-clicking on the link TWICE. These links are dynamically added to the page (a.add-photos-link). Why is this happening and what can I do to fix it so it fires after the first single-click?

• Private VCS hosts for school projects?

  - by Ibrahim

  I want to use version control for a partner project for school, but these days it seems like there are no private, free VCS hosts that I could use. I would prefer to use git if possible, but I wouldn't mind SVN. Alternatively, if there aren't any, shouldn't there be some way for me to use git without a central repository? I don't know enough about git, but I assume that is the point of a DVCS, no? I've considered scp'ing a clone of the repository to my school unix account and then giving my partner access to that, but it seems like it would be a bit of a pain. What are your thoughts/suggestions? Edit: I do know of one site called xp-dev, but I'm not sure how much I trust it. But I could use that and use git-svn on my side, since my partner has actually only ever used svn. But still wondering if there are any alternatives.

• Flash AS3: crop TextField content off at X lines, add '...' at the end

  - by matt lohkamp

  There's only room for three lines of text in the interface, but the content is external and variable, and if it ends up taking up more than three lines, there needs to be some sort of 'view all' button functionality. I can kind of think about what that function needs to look like, but I'm not quite sure what the best way to do it in AS3 would be. Something like (in pseudo code): function cropText(source:TextField, length:int, append:String):TextField{ if(source.lineCount > length){ source.text = // magic function that retuns the first length lines, // minus append.length characters, with the append value tacked onto the end } return source; } ... right? How would you fill in the missing bit?

• Android: Context menu doesn't show up for ListView with members defined by LinearLayout?

  - by RandomEngy

  I've got a ListActivity and ListView and I've bound some data to it. The data shows up fine, and I've also registered a context menu for the view. When I display the list items as just a simple TextView, it works fine: <TextView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/nametext" android:layout_width="wrap_content" android:layout_height="wrap_content"/> However when I try something a bit more complex, like show the name and a CheckBox, the menu never shows up: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content" android:orientation="horizontal"> <TextView android:id="@+id/nametext" android:layout_width="wrap_content" android:layout_height="wrap_content"/> <CheckBox android:id="@+id/namecheckbox" android:layout_width="wrap_content" android:layout_height="wrap_content" /> </LinearLayout> Can long-presses work on more complex elements? I'm building on 2.1.

• Differences between Perl and PHP

  - by lok

  I'm planning to lern Perl 5 and as I have only used PHP until now, I wanted to know a bit about how the languages differ from each other. As PHP started out as a set of "Perl hacks" it has obviously cloned some of Perls features. What are the main differences in the syntax? Is it true that with Perl you have more options and ways to express something? Why is Perl not used for dynamic websites very often anymore? What made PHP gain more popularity than it?

• jQuery preventDefault stops rest of code working

  - by Tim

  I have this code where I am using jQuery to navigate to the next page, because I want some effects to take place before that happens. The problem is, that everything after the prevent.Default(); doesn't seem to work! $("a").click(function(event){ event.preventDefault(); $(".content-center").animate({height: "0px"}, 500); navigate($(this).attr('href')); }); I need things to happen in that order, so that the animation happens and once it's complete - load the next page... Does anyone have any ideas? Many thanks in advance? Tim Updated code (moves to new page but no animation occurs) --- $("a").click(function(event){ event.preventDefault(); var driver = $(this).attr('href'); $(".content-center").animate({ height: "0px" }, 500, function(){ navigate(driver); }); }); see: http://bit.ly/aOeYgE Many thanks for your help!!

• jquery validation of controls

  - by Vinodtiru

  Hi , I am looking at validation of some text boxes for somethings like required, minlength, max length, email etc... I am able to get examples that work fine on submit button on page. I want to do this validation on a button click which will only raise a ajax request and not submit of page. On internet all the sample is found was with submit button. Is there a easy way to change this code a little bit o make it work for non submit button click or any new jquery or java plugin to do the same. I am using the jquery.validation.js for now. This works with submit buttons. Any kind of help with suggestion or help is appreciated. Thanks in advance.

• Scoping inside Javascript anonymous functions

  - by DCD

  I am trying to make a function return data from an ajax call that I can then use. The issue is the function itself is called by many objects, e.g.: function ajax_submit (obj) { var id = $(obj).attr('id'); var message = escape ($("#"+id+" .s_post").val ()); var submit_string = "action=post_message&message="+message; $.ajax({ type: "POST", url: document.location, data: submit_string, success: function(html, obj) { alert (html); } }); return false; } Which means that inside the anonymous 'success' function I have no way of knowing what the calling obj (or id) actually are. The only way I can think of doing it is to attach id to document but that just seems a bit too crude. Is there another way of doing this?

• Thoughts on a Shoutbox anyone?

  - by sologhost

  I'm wanting to create a shoutbox, though I'm wondering if there is another way to go about this rather than using setInterval to query the database for new shouts every number of seconds. Honestly, I don't like having to go about it this way. Seems a bit redundant and repetitive and just plain old wrong. Not to mention the blinking of the shouts as it grabs the data. So I'm wondering on how the professionals do this? I mean, I've seen shoutboxes that work surperb and doesn't seem to be using any setInterval or setTimeout javascript functions to do this. Can anyone suggest any ideas or an approach to this that doesn't use setInterval or setTimeout?? Thanks :)

• ruby on rails state machines

  - by srboisvert

  I'm looking to implement a state machine to manage a user moving through a series of steps over an extended period of time (weeks) with emails and then they interact with the app. I've looked at a couple of AASM plugins and forks (it seems like this plugin space has become a bit chaotic) and am curious what people would recommend. I saw the automatic AASM by hashrocket, that transitions states using cron, and from the title it looks like it might fit the bill but there doesn't appear to be any documentation anywhere and it looks more like a skeleton app than a plugin.

• ReadOnly Property in Custom Column Types in Sharepoint

  - by Ray Booysen

  Hey all I'm creating a custom column in a feature for Sharepoint. It is essentially this: <Field Type="Integer" ID="<insert guid here>" ReadOnly="true" Name="xxx" DisplayName="XXX" Group="YYY" /> When the field is deployed and attached to a content type, the content type shows no instance of this field being attached. The documentation about ReadOnly is a bit vague but definitely states that the column will be available for viewing in a View. However, when I create a view it is not available. The moment I remove ReadOnly from the field, it is available on the content type without any problems. Any ideas?

• Are there any serialization frameworks for java

  - by Grofit

  I know there is simple, which seems to be a decent enough XML serializer and i know there is Jaxb which seems to do the job as well. However im after something a bit more generic, so I could serialize my model to Xml, Json, Binary etc. So the models are just dumb objects that just get thrown into some sort of serialization factory and then the relevant output is spat out... I dont see any reason why you couldn't do this with reflection, so for a REALLY simple solution get the relevent public properties, cut off the get or set and make that the element name... i.e getPersonName() would become <PersonName>xxxx</PersonName> or PersonName:XXXXX

• [Rails] Calling a method from a view using link_to_function

  - by Jeff

  Hello! I'm trying to have an image that when clicked associates the selected guideline to a project. I'm using link_to_function which somewhat behaves but I can not get the method I am calling in the link_to_function to redirect to another page. Is there a better way to do this? Below is a bit of my code. I can paste in additional parts if necessary: <% @guidelines.each do |guideline| %> <tr> <td align='center'><%= link_to_function image_tag("../../../images/icons/action_add.png"), add_guideline(guideline) %></td> <td><%=h guideline.title %></td> My GuidelinesController.helper method looks like this: def add_guideline(guideline) @project = Project.find(params[:project_id]) @project.guidelines << guideline @project.save redirect_to dashboard_path #doesn't work :( end

• Can’t tap button after interface rotation

  - by zoul

  Hello! I’ve got a view that has to be presented both in landscape and portrait. The transition between different orientations is done by repositioning and resizing the subviews. One of the subviews is a button (plain UIButton with an image background). When the interface rotates to landscape, the button starts misbehaving – it can only be tapped on its left part, the right part does not respond. When I move the button a bit to the left, the tappable part grows. The button should not be obscured by any other view, it’s clearly visible. When I override the hitTest:withEvent: method in the parent view, I see that the taps in the “numb” part of the button result in nil being returned. I think I have seen this behaviour once before, but unfortunately I’ve forgotten the source of the problem :) Any help?

• Large Scale VHDL modularization techniques

  - by oxinabox.ucc.asn.au

  I'm thinking about implimenting a 16 bit CPU in VHDL. A simplish CPU. ADD, MULS, NEG, BitShift, JUMP, Relitive Jump, BREQ, Relitive BREQ, i don't know somethign along these lines Probably all only working with 16bit operands. I might even cut it down and use only a single operand and a accumulator. With Some status regitsters, Carry, Zero, Neg (unless i use a Accumlator), I know how to design all the parts from logic gates, and plan to build them up from first priciples, So for my ALU I'll need to 'build' a ADDer, proably a Carry Look ahead, group adder, this adder it self is make up oa a couple of parts, wich are themselves made up of a couple of parts. Anyway, my problem is not the CPU design, or the VHDL (i know the language, more or less). It's how i should keep things organised. How should I use packages, How should I name my processes and port maps? (i've never seen the benifit of naming the port maps, or processes)
