• @Local annotation in EJB 3.

  - by stratwine

  Hi, I have a stateless session bean and a standalone-java-program acting as a client. The bean method executes just fine when the interface is marked @Remote. However,when I mark that interface with @Local instead of @Remote, I get the following Exception. [java] javax.naming.NamingException: Could not dereference object [Root exception is java.lang.RuntimeException: Could not find InvokerLocator URL at JNDIaddress "chapter1/HelloUserBean/local"; looking up local Proxy from Remote JVM?] But I expected even the latter to work, since it is the same computer that the code executes in. Seeing this behavior, I am assuming that, the Application-Server and the Standalone-Java-Program use different JVM instances and not a single JVM instance and so this client can access only through a remote interface. Is that assumption correct ? Thanks !

• Removing the Default Wrap Character From all records

  - by aceinthehole

  I am using BizTalk 2009 and I have a flat file that is similar to the following "0162892172","TIM ","LastName ","760 "," ","COMANCHE ","LN " "0143248282","GEORGE ","LastName ","625 "," ","ENID ","AVE " When I parse it and start mapping it I need to get rid of the quotation marks. I have marked the Wrap Character attribute for the schema as a quotation mark but it doesn't remove it when BizTalk is parsing the file. Is there an easy way to specify the removal of a wrap character or am I going to have to run it through a script functiod every time? Also I would like to be able to remove the trailing spaces as well, if at all possible.

• Add the "selected" attribute to a drop down option with jQuery

  - by gaoshan88

  How do I add the attribute "selected" to a drop down menu option based on that option matching some variable? Here is how the dropdown is populated... loginOptions = ["First", "Second", "Third]; var Login = $( '#Login' ); for ( var i = 0; i < loginOptions.length; i++ ) { Login.append('<option value="'+ loginOptions[i] +'">'+ loginOptions[i] +'</option>'); } I want to mark one option as "selected" based on whether or not its value matches another variable. so if loginOption[i] is equal to var existingLoginValue then set that option to 'selected' Something that would do if(loginOptions[i] === existingLoginValue){ print 'selected'; }; Thanks!

• How can I copy a queryset to a new model in django admin?

  - by user3806832

  I'm trying to write an action that allows the user to select the queryset and copy it to a new table. So: John, Mark, James, Tyler and Joe are in a table 1( called round 1) The user selects the action that say to "move to next round" and those same instances that were chosen are now also in the table for "round 2". I started trying with an action but don't really know where to go from here: def Round_2(modeladmin, request, queryset): For X in queryset: X.pk = None perform.short_description = "Move to Round 2" How can I copy them to the next table with all of their information (pk doesn't have to be the same)? Thanks

• Any particular reason why FaceBook's Subscribe Button isn't showing on my web page?

  - by Axonn

  I got this FaceBook profile for my upcoming website and I can't get the Subscribe button to show, NOT EVEN ON FaceBook's page! http://www.facebook.com/profile.php?id=100003492130845 Now, if you go here on FaceBook's page where we build the Subscribe button: http://developers.facebook.com/docs/reference/plugins/subscribe/ And add the above link, it will show nothing. I enabled subscribing and I also created myself a page, linked to the same profile: http://www.facebook.com/pages/Axonn-Says/372194956141393 But not even the page works ::- /. LATER EDIT: I temporarily added 2 other Subscribe buttons on my website to demonstrate that it works for example for Mark Zuck's page and to demonstrate that there are no JS conflicts. The 2 buttons appeared ok, but my button still didn't show up.

• For simple C cmd programs: how to add "program executed in 12,345 seconds" ?

  - by WoodsieLord

  I'm a windows user, and I'm learning C. I use Codeblocks and visual c++ 2008 express at home to write simple C command line programs (I'm a beginner) and I find really useful when codeblocks adds a few lines at the end with the time it takes (example: "Process returned 0 (0x0) execution time : 6.848 s"). I want to add this functionality to the .exe so I can 'benchmark' or 'test' the program on a few computers. I tried using time(NULL) but it only works with 1 second precision. I also found very interesting answers here (I'm actually looking for the same thing): http://stackoverflow.com/questions/2173323/calculating-time-by-the-c-code The solution proposed by Mark Wilkins, works fine on visual c++ 2008 express on my windows 64 bit PC, but the .exe does not work anywhere else. Am I doing something wrong? I would like a method to count elapsed wall time for my programs, that must have 32bit compatibility. Thanks in advance!

• Flagging complex properties as Browsable in the compact framework

  - by Rowland Shaw

  I'm working on a compact framework project and whilst most of the properties are fairly straight forward (I.e. mark them as browsable in the xmta file), I'm struggling to get this to work for more complex types - on the full framework, I'd just implement a custom TypeConverter and go from there, but it seems the CF TypeConverter doesn't have any of the type converting methods to override, which has left me a little stuck? It probably should be blindingly obvious but how would I go about supporting design time property support for more complex types (for the sake of argument, assume I can already convert to and from a string, but I'd prefer to keep this strongly typed, rather than just pretend it was a string and parse it both ways. Where should I be looking to achieve this?

• Tooltip equivalent for touch devices?

  - by eteubert

  Hey folks, Touch devices are on the rise. More and more website developers try to optimize their pages for those devices. Until recently the most common solution was to build a mobile version for the website. But with tablets this will most likely change to adjusting the original pages to be touch compatible. One big issue I encountered are tooltips. There are some websites and web applications relying heavily on storing important informations in some kind of tooltip triggered by hovering the mouse arrow over some interface element - which does not exist on touch devices. So what do you think is a good universal way to adopt these pages without redesigning the site from scratch? Does this universal way even exist? My first idea was a tiny touchable question mark but this would hardly be big enough for a finger.

• NameValueCollection Issue In Proxy Generation

  - by N W. annor-adjei

  I have a proxy generation problem I am building my own customised XMLMembershipProvider in WCF. The code runs well in ASP.Net and am consuming the same code in WCF for silverlight, My class inherits the Membership provider hence have implemented all the MembershipProvider methods. Now, consumung this methods in WCF requires also the Initialize Method having NameValueCollection as passin parameter, which is the cause of the problem because WCF does not supporteCollection serialization. when the initialize method is marked as OperationContract, Proxy class does not get generated. I could have use Dictionary but that is impossible here bacause the base class's initialize method accepts two parameter one of which should be a NameValueCollection. If i don't mark the Initialize as OperationContract, the proxy class is generated with all the methods but i realized i still need the Initialize marked as Operation contract to start the provider. Has any one got any idea about the use of NameValueCollection in WCF and the work around this problem Thank you. Nicholas

• Could I use Revert after abrupting Merge?

  - by John

  Hallo all, Just now I tried to upload a modified working copy to its branch in the following steps: 1. Update 2. Commit Then I attempted to Merge the changes in the trunk to this branch. However during editing of the conflicts I realized there were so many conflicting codes that I could not address completely today, then I gived up the Merge, and the working copy got an exclamation mark immediately. Thru Check for modifications I found that many many files had been modified or had conflicts. It seems that the Merge has been somehow wrongly carried out. My question: could I return to the state before the Merge simply using Revert? Thanks a lot in advance, John

• jQuery DataLink - Does DataLink solve my use case?

  - by AnApprentice

  Hello, I recently heard of the jQuery datalink plugin and wondered if I should be using if for the following: I have a an inbox in my app that consists of the following: Inbox (index) - List of Items (list of mails) Inbox (show) Item Viewer (1 mail) Inbox Unread Counter The challenge I'm having now is a user can mark a mail as read/unread in either view which makes keeping the counter accurate challenging. Can datalink help with this? If so how? Also, I read that datalink requires forms is that true? Or can I bind the links to anything like 0 and anytime a mailitem changes from read to unread it would automatically update? Thanks

• Save user favorites

  - by Radu D

  Hi, In my application I need to display items to the user. He can mark some items as favorites. I need to display those differently. How can I save the favorites on the user's computer? I need something like a config entry ... but I need to change that as the user add/remove the favorites. Do you think that I should save that in registry ... or on the disk in a separate file? Does .net offers some support for such situations? Thanks, Radu

• Chrome vs Safari - CSS the mystery pixel

  - by Aji

  I have an issue of the mysterious pixel in CSS. Site in question: http://www.lymphcareri.com/about/ The idea is that under the menu is a line, which gets highlighted upon hover and blends in with the line under the header. However, Safari and Chrome both interpret the CSS different in such a way, that I cannot get those lines to line up in both browsers (no pun intended). It is either on the mark, or off. Chrome shaves off one pixel on the bottom margin of the nav link, making the line appear just above. Any idea why that is?

• DOM class injection in PHP

  - by Adam Kiss

  idea Via jQuery, I was able to mark all :first-child and :last-child elements in document (well, almost all :)) with class first which could I later style (i.e. first li in ul#navigation would be easily adressable as ul#navigation .first). I used following code: var $f = $('*:first-child') $f.addClass('first'); var $l = $('body *:last-child') $l.addClass('last'); question Now, my question is if it's possible to do the same via php, so non-JS users/gadgets could have the same effects and additional styling and also it would be less overkill on browser. So, is it possible to capture output, parse it as html and inject this class easily in php?

• Do you have to create a View Controller to move between views?

  - by Frames84

  I want a single startup view with a button and a welcome screen. When the button is pressed I then want to navigate to a second view which contains a table view and toolbar. I've tried creating a ViewController but my button is shown on all views. I just want a single view, then when it's pressed i go to the next view and the 'real' app starts. Can someone please try and explain the best architecture to do this? (like in chapter 6 of beginning iPhone 3 Development by Dave Mark and Jeff LaMarche ) Thanks

• Explanation needed for sum of prime below n numbers

  - by Bala Krishnan

  Today I solved a problem given in Project Euler its problem no 10 and it took 7 hrs for my python program to show the result. But in that forum itself a person named lassevk posted solution for this and it took only 4 sec. And its not possible for me to post this question in that forum because its not discussion forum. So, think about this if you want to mark this question as non-constructive. marked = [0] * 2000000 value = 3 s = 2 while value < 2000000: if marked[value] == 0: s += value i = value while i < 2000000: marked[i] = 1 i += value value += 2 print s If any one understand this code please explain it simple as possible. Link to the Problem 10 question.

• distinguishing a string with flex

  - by haluk

  Hi, I need to tokenize some strings which will be splitted of according to operators like = and !=. I was successful using regex until the string has != operator. In my case, string was seperated into two parts, which is expected but ! mark is in the left side even it is part of given operator. Therefore, I believe that regex is not suitable for it and I want to benefit from lex. Since I do not have enough knowledge and experience with lex, I am not sure whether it fits my work or not. Basically, I am trying to do replace the right hand side of the operators with actual values from other data. Do you people think that can it be helpful for my case? Thanks.

• "import as" leads to unresolved import error, "from .. import" does not

  - by Markus R.

  I'm trying to write some plugins for the irc bot supybot with eclipse/pydev. Pydev gives me errors about unresolved imports on supybot-modules/packages (e. g. import supybot.utils as utils), but works ok on e. g. "from supybot.commands import *". So I guess I set up dydev correctly, as it finds the wanted modules. The problem must be in pydev/eclipse, as the bot works correct and in eric5 I get also no errors about that. Removing the interpreter and setting it up didn't help. Any other ideas on how to fix this? System: Arch Linux, Eclipse Juno, PyDev 2.7.1, wanted (and set up) python interpreter is 2.7, supybot is installed in site-packages for Python 2.7. Edit: Just noticed: PyDev doesn't mark the "from ... import *" as error, but if I use functions imported from there I get an error on that function.

The project shows up but with a red exclamation mark and an error saying: "The project cannot be built until build path errors are resolved" Can somebody help me out with this? I tried this http://www.scottdstrader.com/blog/ether_archives/000921.html but it didn't work. Also, are there any good ways of syncing an eclipse workspace across multiple computers?

• Unexpected key-value behavior in a Core Data Context

  - by ????

  If I create an array of strings (via key-value coding) containing the names of a Managed Object entity's attributes which are stored in the App Delegate the first time, I get an array of NSStrings without any problems. If I subsequently make the same call later from the same entry point in code, that same collection becomes an array of NULL objects- even though nothing in the Core Data Context has changed. One unappealing work-around involves re-creating the string array every time, but I'm wondering if anyone has a guess as to what's happening behind the scenes. // Return an array of strings with the names of attributes the Activity entity - (NSArray *)activityAttributeNames { #pragma mark ALWAYS REFRESH THE ENTITY NAMES? //if (activityAttributeNames == nil) { // Create an entity pointer for Activity NSEntityDescription *entity = [NSEntityDescription entityForName:@"Activity" inManagedObjectContext:managedObjectContext]; NSArray *entityAttributeArray = [[NSArray alloc] initWithArray:[[entity attributesByName] allValues]]; // Extract the names of the attributes with Key-Value Coding activityAttributeNames = [entityAttributeArray valueForKeyPath:@"name"]; [entityAttributeArray release]; //} return activityAttributeNames; }
