• How to implement thread timeout in J2ME?

  - by lilo

  I am using Connector in J2ME and found that sometimes it take a very long time to send a request, and sometime it may halt the whole process. So I try to put code related to Connector in a thread and try to set timeout to the thread. But I found out that it's very difficult to do this in J2ME because there's no join(long) in J2ME. Is there any way to do this? Or any better way to deal with network connection in J2ME? Thanks a lot in advance.

• Low overhead Java Web Services container?

  - by trojanfoe

  I want to provide a Java-based Web Service, but I don't require the features of a full-blown J2EE Application Server. I would like it to start as quickly as possible, though that's not a hard requirement. The Web Service will handle multiple connections and require access to an Oracle database so it will at least require a thread pool and database connection pool. I may want to put a JSP interface onto it later to provide an internal maintainence interface. I have looked at Jetty with an Apache CXF stack, but it looks like I'll have to do a fair amount configuration before even coding the web service - Will it be worth it? Will it even work? Should I forget about the complexity and simply go with JBoss/Weblogic/etc and put up with the bloat and extra start-up time?

• Java and Different Types of Stacks

  - by Rarge

  Currently the only stack I know anything about is Vector, I normally use this in place of an array but I understand that there is other types of stacks and they all suit different jobs. The project I am currently working on requires me to be inserting objects in a certain position inside a stack, not always the front of the stack and I am under the impression that a Vector may not be the best class for this job. Could somebody please give me a brief description of the other types of stacks available to me with the Java language and their advantages and disadvantages? Are these names homogeneous? E.g. Are they only used in the Java language or are they used as general terms in Computer Science? Thank you

• how to test if a string is a valid UTF16 string?

  - by superb

  I am using mongodb and javascript to do some string processing. Now I got some error like: Sun May 23 07:42:20 Assertion failure JS_EncodeCharacters( _context , s , srclen , dst , &len) scripting/engine_spidermonkey.cpp 152 0x80f4f7e 0x80f8794 0x811525b 0x811a953 0x8119fc4 0x8111bc5 0x81b408e 0x81c4ee7 0x81b4a10 0x817a881 0x817a7d8 0x817a6e2 0x811e1bb 0x80a777b 0x80a8f8a 0xb7cb2455 0x80a37a1 mongodb-linux-i686-1.4.2/bin/mongo(_ZN5mongo12sayDbContextEPKc+0xfe) [0x80f4f7e] After doing some google, I find that JS_EncodeCharacters return false if the input is not a valid UTF16 string. (if spidermonkey is build with UTF-8 enabled) So I was wondering how to test if the input string if a proper UTF16 string? so I can skip such kind of string to avoid problem ... Thanks

• How do I save a file generated by an OS X Dashboard Widget?

  - by Weston C

  I've got a web app that I'm porting to an OS X Dashboard widget. The web app generates some data on the client side using JavaScript, and then, when the user wants to save it, sends it to a server-side script which relays the data back with the Content-disposition: attachment; HTTP header, triggering a save-file dialog in most browsers. I've tried duplicating this in the Dashboard environment. The Widget simply disappears. I don't know, but I suspect that it may be actually navigating to the unfamiliar content. So, how do I trigger a "save file dialog" -- or, failing that, use any method at all to save the data the Widget generates as a file?

• Help with variables and new lines, and quoting in a bash script

  - by Scott

  I would like to automate the following svn command. Note this command produces the desired results on my system - Ubuntu 10.04, svn 1.6.6, bash shell, when issued from the command line: svn ci -m $'Added new File: newFile.txt\nOrig loc: /etc/networking/newFile.txt' /home/user/svnDir/newFile.txt I would like to run that command in a bash script, assuming that the original full path to the file is contained in the variable $oFileFull, and the filename is in $oFileName. The script is executed from the svn directory. I need to allow for the possibility that the file name and or path contain spaces. so the line inside my shel script might look like: svn ci -m$'Added new file: ${oFileName}\nOrig loc: ${oFileFull}' ${oFileName} But I want the variables (which may contain spaces) expanded before the command is executed, and I cannot figure out how to do this while enclosing the svn comment in single quotes which is necessary in order to get the new line in the subversion comment log. I am pulling my hair out trying to figure out how to properly quote and assemble this command. Any help appreciated.

• Ant var and property scope

  - by bobtheowl2

  I have a main build script that calls various targets. One of these targets needs to store a value and another target needs to display it. Obviously this is not working so I think it may be related to scope. I've tried var, property, and declaring the property outside of target1. Since var seems to be mutable, it looks like I need to use it instead, but each time my output is empty. Main script <antcall target="target1"/> <antcall target="display"/> In target1: <var name="myVar" value="${anotherVar}"/> In display: <echo>${myVar}</echo>

• border highlighting loop with jquery

  - by Tek

  I'm having trouble coming up with a loop that changes the border color of an image from black to yellow and yellow to black over x seconds. Then applying an interrupt to the loop when the image gets clicked on. I don't know where to start, can someone point me in the right direction? I think I may be using the wrong tools to properly write this. Here's what I've come up so far, though if there's a better way to write this, do share! for( i = 100; i >= 0; i--) { $("#imgid").css("border-color", 'rgb(' + i + '%,' + i + '%,0)'); } I'm having trouble picturing how I could combine two loops so that I can also count upwards as well so that it will turn into yellow and back to black. I also don't know how to go about controlling the amount of time it takes for that loop to execute and creating an interrupt when #imigid is clicked. Which is where I'm not sure how to write.

• Is Sphinx better than LaTex in writing manuals/books?

  - by Masi

  Only a few people recommended to use Sphinx at the beginning of the year. Sphinx has developed rather fast recently. I noted today that Sage has made a change from direct editing with LaTex to Sphinx. This is evident in William Stein's answer on 2nd April about Sage's tutorial The tutorial is not a latex document anymore. It's an entirely different Sphinx document that can output pdf. It suggests me that Sphinx may be at a level such that it is suitable for me. Is Sphinx better than LaTex in writing manuals/books?

• Disadvantages of hard coding credentials? What's the resolution?

  - by SeeBees

  I am building a Sharepoint web part that will be used by all users. The web part connects to a web service which needs credentials with higher privileges than common users. I hard coded credentials in the web part's code. query.Credentials = new System.Net.NetworkCredential("username", "password", "domain"); query is an instance of the web service class This may not be a good approach. In regard with security, source code of the web apart is available to people who are not allowed to see the credential. This is bad enough, But is there any other drawback of this approach? How to prevent hard coding credentials into the source code? Thanks

• help designing a method, should I use out or ref or return the type?

  - by Blankman

  I have a method that I will use in the following contexts: 1. User user = null; if(...) { user = defaultUser; SetUser(a,b,user); } else { SetUser(a,b,user); } SaveUser(user); So some cases are where user may be null, while in other cases it will already be initialized. How should I design the SetUser method? I currently have it like so, but this causes an error when user is null. public void SetUser(object a, object b, User user) { if(user == null) user = new User(); user.Security = a.security; user.Blah = b.type; }

• CQRS, Commands, Javascript

  - by Tolu

  I have an architecture where a task-based UI passes commands to a service layer. Now, my intention is to implement the UI in javascript, using KendoUI and the service layer, domain layer etc. in .NET. I'm also looking at future mobile implementations of the client that may use say Java rather than Javascript. If I define the commands in .NET, I'd like to know how to use them from my Javascript client so the client can communicate the commands appropriately to service layer. Do I have to use something like Apache Thrift for this i.e. to define the commands at both the client and service layer?

• Database permissions and ORMs

  - by Jonn

  I've been using .NET's Entity Framework a lot lately and have absolutely no wish to go back to using Stored Procedures. Been shocked though that the company I'm building this project for had a policy where applications were only given accounts that only had permissions to access stored procedures! Apparently, they believe that there's a security risk involved in allowing applications to access the tables/views directly. I don't get this. My first question is, can someone enlighten me as to what kind of security risk applications having direct access to the database may pose? AND If that's the case, are there any other ORM solutions that can provide a workaround to this (I can't think of any logical possibility atm) that would allow me to circumvent the restrictions on the user account to be assigned to me? OR is my understanding that I'd need direct permissions for the tables and views wrong?

• Wordpress items catalogue plugin

  - by cosmorocket

  Could you please recommend me a plugin for Wordpress or may be a tiny standalone php script that allows to add some items with text info and a photo to a database, XML or just a text file from a special admin page. Then I need to fetch these items from the source and show in the page some way. To understand the task better, please check this page http://treaky.com/denis/products-classiccare.html. There is a main area that shows items but now it's just a dummy html to see how it should look in the end. Thank you!

• Optimizing Dijkstra for dense graph?

  - by Jason

  Is there another way to calculate the shortest path for a near complete graph other than Dijkstra? I have about 8,000 nodes and about 18 million edges. I've gone through the thread "a to b on map" and decided to use Dijkstra. I wrote my script in Perl using the Boost::Graph library. But the result isn't what I expected. It took about 10+ minutes to calculate one shortest path using the call $graph-dijkstra_shortest_path($start_node,$end_node); I understand there are a lot of edges and it may be the reason behind the slow running time. Am I dead in the water? Is there any other way to speed this up?

• How do I get the path of the current executed file in python?

  - by Sorin Sbarnea

  This may seam a newbie question but it is not. It looks that common approaches are not always working: Currently I know only two options but none of them looks to work an all cases. sys.argv[0] This means using path = os.path.abspath(os.path.dirname(sys.argv[0])) but this does not work if you are running from another python script from another directory, and this can really happen in real life. __file__ this means that path = os.path.abspath(os.path.dirname(__file__)) but I found that this doesn't work: py2exe that doesn't have a __file__ attribute but there is an workaround. when you run from IDLE with execute() there is no __file__ attribute OS X 10.6 where I get NameError: global name '__file__' is not defined Related questions with incomplete answers: http://stackoverflow.com/questions/1296501/python-find-path-to-file-being-run http://stackoverflow.com/questions/1483827/python-path-to-current-file-depends-on-how-i-execute-the-program http://stackoverflow.com/questions/2259503/how-to-know-the-path-of-the-running-script-in-python http://stackoverflow.com/questions/509742/python-chdir-to-dir-the-py-script-is-in

• How to deal with the new line character in the Silverlight TextBox

  - by Ian Oakes

  When using a multi-line TextBox (AcceptsReturn="True") in Silverlight, line feeds are recorded as \r rather than \r\n. This is causing problems when the data is persisted and later exported to another format to be read by a Windows application. I was thinking of using a regular expression to replace any single \r characters with a \r\n, but I suck at regex's and couldn't get it to work. Because there may be a mixture of line endings just blindy replacing all \r with \r\n doesn't cut it. So two questions really... If regex is the way to go what's the correct pattern? Is there a way to get Silverlight to respect it's own Environment.NewLine character in TextBox's and have it insert \r\n rather just a single \r?

• Access 2007 - Forms created on the fly

  - by glinch

  Hi There, Hopefully I can find some words of advice from somebody. Is it possible to create forms 'on-the fly' so to speak in MS-Access 2007 I have a structure of tables: tblCustomer tblQuestAns A customer may answer the questionnaire answers many times as they relate to all products. I propose to hopefully have an initial input form that will ask how many products of which there could be more than 1 eg: TV, Video (say the user selects 2) On entering that data the next form should hopefully update itself to include the list of questions eg TV Q1, Q2 Q3 - Video (1) Q1, Q2 Q3 - Video (2) Q1, Q2 Q3 Is that possible? Any point in the right direction would be appreciated. Thanks Noel

• Spring and JUnit annotated tests: creating fixtures in separate transactions

  - by Francois

  I am testing my Hibernate DAOs with Spring and JUnit. I would like each test method to start with a pre-populated DB, i.e. the Java objects have been saved in the DB, in a Hibernate transaction that has already been committed. How can I do this? With @After and @Before, methods execute in the same Hibernate transaction as the methods decorated with @Test and @Transactional (first level cache may not be flushed by the time the real test method starts). @BeforeTransaction and @AfterTransaction apparently cannot work with Hibernate because they don't create transactions even if the method is annotated with @Transactional in addition to @Before/AfterTransaction. Any suggestion?

• Circular dock/menu in css or jquery

  - by sasidhar

  Is it possible to have a circular menu or dock using css or jquery.? I have a set of images as the dock items that need to be displayed as a circular dock... however the number of items in the dock are not constant and may vary.... so i cannot tend to use constant values for positioning each item in a pre-defined manner. Ajax loads some images into this particular div and i need to use css or jquery to style this so that they get displayed as circular dock items. Any idea on how this can be implemented..? I would like a browser in-specific implementation, but i also welcome if some one has some solutions specific to few browsers... UPDATE I don't think i exactly want a pie menu... it easily gets messed up as the number of dock items increase. I am looking for a spiral dock. and by spiral i mean that the menu items must be in the following alignment..

• What is branched in a repository?

  - by Peter M

  Ok I hope that this will end up sounding like a reasonable question. From what I understand of subversion if you have a repo that contains multiple projects, then you can branch individual projects within that repo (see SVN Red book - Using Branches) However what I don't quite follow is what happens when you create a branch in one of the distributed systems (Git, Hg, Bazaar - I don't think it matters which one). Can you branch just a sub-directory of the repo, or when you create the branch are you branching the entire repo? This question is part of a larger one that I posted on superuser (choice and setup of version control) and has come about as I am trying to figure out how to best version control a large hierarchal layout of independent projects. It may be that for distributed systems that what I would like to do is best handled by a sub-project mechanism of some sort - but again that is something I am not clear on although I have heard the term mentioned in regards to git.

• RSS-Feed or XML-Stream?

  - by Maenny

  HI Folks, I am programming a website for online-reservation-management, preferably for holiday homes. I want to implement a service, which allows the user to pass all their occupation dates to other websites. My question is, what would be the most professional way to do this? Generate a XML-stream Create a valid RSS Feed I think that a XML file has the advantages of being straight to the point, without any information that noone needs. Webmasters of other websites surely prefer the structure of a simple XML file. On the other hand, when someone without programming knowledge wants to use the RSS-Feed with a feedreader or simply with the browser, it may be user-friendlier to use a RSS-FEED. What so you think, I'm unsure...? Greetz Maenny

• ant support for dynamic target

  - by Li He

  I previous saw some similar questions on stackoverflow but didn't see any solution. I guess the answer could be impossible and I am trying to see who can provide me this confirmation. AFAIK, an ant project contains several targets and each target may have several tasks. There is an task MacroDef that defines a sequential of `things' (tasks I suppose?). I tried to put target inside this block but ant complains the name of the target is missing (I am using the attribute of the macrodef to generate the name of the target). So it could be a dead end. Then I found that by using a task `script', we have access to the Project and can even call addTarget/AddOrReplaceTarget from there. But it seems that the targets I create there have no impact on the running targets. Does that mean ant doesn't support manipulating dependencies at target runtime? Is there any way to generate these targets before ant start building the dependency graph?
