  • Specifying Locations relative to the context XML in Spring

    - by Daisuke Shimamoto
    Is there a way to reference a properties file relative to the Spring's context file itself? What I want to do is the below: <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="locations"> <list> <!-- I want the below to be relative to this context XML file. --> <value>app.properties</value> </list> </property> </bean> I was imagining something like ${contextpath} that I could prepend to the above "app.properties" but couldn't find anything helpful. Thanks.

  • Is this a good approach to dealing with tagging?

    - by Mel
    Can this code be optimized or re-factored? Is this an optimal approach to tagging? The following code is a callback in my posts model. It creates a record that associates a tag with a post in a QuestionsTags joiner table. When necessary, if a given tag does not already exist in the tags table, the function creates it, then uses its id to create the new record in the QuestionsTags table. The difficulty with this approach is the QuestionsTags table depends on data in the tags table which may or may not exist. The function assumes the following tables: tags(id, tagName), posts(tags) // Comma delimited list questionsTags(postId, tagId) The idea is to loop over a delimited list of tags submitted with a post and check to see if each tag already exists in the tags table If tag exists: Check to see if there's already a QuestionTag record for this post and this tag in the QuestionTags table. If yes, do nothing (the association already exists) If no, create a new QuestionTag record using the id of the existing tag and the postId If tag does not already exist: Create the new tag in the tags table Use its id to create a new QuestionsTags record Code /** * @hint Sets tags for a given question. **/ private function setTags() { // Loop over the comma and space delmited list of tags for (local.i = 1; local.i LTE ListLen(this.tags, ", "); local.i = (local.i + 1)) { // Check if the tag already exists in the database local.tag = model("tag").findOneByTagName(local.i); // If the tag exists, look for an existing association between the tag and the question in the QuestionTag table if (IsObject(local.tag)) { local.questionTag = model("questionTag").findOneByPostIdAndTagId(values="#this.postId#,#local.tag.id#"); // If no assciatione exists, create a new QuestionTag record using the tagId and the postId if (! IsObject(local.questionTag)) { local.newQuestionTag = model("questionTag").new(postId = this.id, tagId = local.tag.id); // Abort if the saving the new QuestionTag is unsuccesful if (! local.newQuestionTag.save()) { return false; } } } // If the tag does not exist create it else { local.newTag = model("tag").new(tagName = local.i, userId = this.ownerUserId); // Abort if the the new tag is not saved successfully if (! local.newTag.save()) { return false; } // Otherwise create a new association in the QuestionTags table using the id of the newly created tag and the postId local.newQuestionTag = model("questionTag").new(postId = this.id, tagId = local.newTag.id); // Abort if the new QuestionTag does not save correctly if (! local.newQuestionTag.save()) { return false; } } } } FYI: I'm using CFWheels in my application, which explains the ORM functions used.

  • Netbeans Intellisense for Rails

    - by irishfury
    Has anybody figured out a way to make the Netbeans intellisense for ruby and rails better? It either has too many options in the list (which I understand is a problem since it is a dynamic language). Or it has no options in the list, as if it is not dynamic enough to find everything. Are there any hacks to make it better, or is this just something that needs to be improved within the Netbeans source code? I'm currently using 6.8. Please spare me the posts about how I don't really need to use intellisense, and I should use vim or emacs. I'm sure the vim programmers are 10 times more productive than me with all their cool shortcuts, but I have no desire to learn these tools.

  • Struts 2: redirect-action ? From on page to another and back again.

    - by Stephan
    Hello, i have a jsp page that has a submit button. This button is linked with another jsp page. So lets assume my stuts file looks like this: B.jsp So now the submit button being on page "A.jsp" will take me to B.jsp. This works. The problem is that i want to do the following: press on the submit button on page A.jsp , go to B.jsp where i will press again a button and go back to A.jsp . The problem is that to page B.jsp go many pages, so B.jsp has to know when pressing the submit button to which page will take me back , in this case A.jsp again. So in a few words, B.jsp has to know from which page i came from so that i can go back again by pressing a submit button (this could be a parameter that would be sent back to A.jsp again, but does not really matter at the current point) A.jsp - B.jsp - A.jsp C.jsp - B.jsp - C.jsp

  • C# LINQ join With Just One Row

    - by Soo
    I'm trying to make a query that grabs a single row from an SQL database and updates it. TableA AId AValue TableB BId AId BValue Ok, so TableA and TableB are linked by AId. I want to select a row in TableB based on AValue using a join. The following query is what I have and only grabs a value from TableB based on AId, I just don't know how to grab a row from TableB using AValue. I know you would need to use a join, but I'm not sure how to accomplish that. var row = DbObject.TableB.Single(x => x.AId == 1) row.BValue = 1; DbObject.SubmitChanges();

  • How to implement collection with covariance when delegating to another collection for storage?

    - by memelet
    I'm trying to implement a type of SortedMap with extended semantics. I'm trying to delegate to SortedMap as the storage but can't get around the variance constraints: class IntervalMap[A, +B](implicit val ordering: Ordering[A]) //extends ... { var underlying = SortedMap.empty[A, List[B]] } Here is the error I get. I understand why I get the error (I understand variance). What I don't get is how to implement this type of delegation. And yes, the covariance on B is required. error: covariant type B occurs in contravariant position in type scala.collection.immutable.SortedMap[A,List[B]] of parameter of setter underlying_=

  • ZF Site in ZF Site? How do I redirect form subdirectory to another subdirecotry?

    - by AD
    The deal is that I have a ZF site for which root directory is /public. How should I go about redirecting to a subdirectory if I want to do next? I want to have another subdirectory under /public/ that would not be linked to a main website in any way except it using save ZF. Lets say I have this: /public/newsite/ which will include a complete modular ZF (just I have it for the main site). That is the root directory for the NEWSITE would be /public/newsite/public. So my question how do I modify my .htaccess rules so it would redirect any requests from /public/newsite/ to /public/newsite/public/? Thank you in advance.

  • Is there any way to disable the "double-click to copy" functionality of a .NET label?

    - by DavidCarroll
    This is really annoying. I'm using the label as part of a list item user control, where the user can click it to select the list item and double-click it to rename it. However, if you had a name in the clipboard, double-clicking the label will replace it with the text of the label! I've also check the other labels in the application, and they will also copy to the clipboard on a doubleclick. I have not written any clipboard code in this program, and I am using the standard .NET labels. Is there any way to disable this functionality?

  • javascript ul button dropdown crashes after if doing more than 1 button

    - by Apprentice Programmer
    So i have a button drop down list that i want users to select a choice, and basically the button will return the users selection.Pretty straight forward, tested on jsFiddle and works great. Using ruby on rails btw, so i'm not sure if it might conflicting the way rails handle javascript actions. Heres the code: <%= form_for(@user, :html => {:class => 'form-horizontal'}) do |f| %> <fieldset> <p>Do you have experience in Business? If yes, select one of the following: <div class="input-group"> <div class="input-group-btn btn-group"> <button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown">Select one <span class="caret"></span></button> <ul class="dropdown-menu"> <li ><a href="#">Entrepreneurship</a></li> <li ><a href="#">Investments</a></li> <li ><a href="#">Management</a></li> <li class="divider"></li> <li ><a href="#">All of the Above</a></li> </ul> </div><!-- /btn-group --> <%= f.text_field :years_business , :class => "form-control", :placeholder => "Years of experience" %> </div> Now there are 2 more of these, and basically what happens is that if I select an item for the first time from the dropdown list, everything works great. But the moment I select the same button/or new button, the page immediately kind of refreshes, they selected value will not show up after the list drops down and user selects a value. I viewed the page source and added additional javascript src and types, but still doesnt work. the jquery code: jQuery(function ($) { $('.input-group-btn .dropdown-menu > li:not(.divider)').click(function(){ $(this).closest('ul').prev().text($(this).text()) }) }); Any suggestions what is causing the problem?? The jsfiddle link is here: http://jsfiddle.net/w4s8u/7/

  • Javascript / Jquery Tree Travesal question

    - by Copper
    Suppose I have the following <ul> <li>Item 1</li> <li>Item 2 <ul> <li>Sub Item</li> </ul> </li> <li>Item 3</li> </ul> This list is auto-generated by some other code (so adding exclusive id's/class' is out of the question. Suppose I have some jquery code that states that if I mouseover an li, it gets a background color. However, if I mouseover the "Sub Item" list item, "Item 2" will be highlighted as well. How can I make it so that if the user mouses over "Sub Item" it only puts a background color on that and not on "Item 2" as well?

    - by dev-cu
    I know there are good books to start with, but let's make a short list of 3-5 books, i don't think only one book could help you in the way of becoming a good architect. I read some time ago that an architect takes years to have the knowledge and the ability to make good decisions. Suppose someone has the potential, what is the way? Please, answers with books that doesn't repeat over the same theme, making your learning process widely. One short list per answer. Vote up that you think are the best ones. Thanks.

  • Setting a property from one collection to another collection

    - by ooo
    I have two colluections List<Application> myApps; List<Application> yourApps; These lists have overlapping overlapping data but they are coming from different sources and each source has some missing field data. Application object has a property called Description Both collections have a unique field called Key i want to see if there is a LINQ solution to: Loop through all applications in myApps and look at the key and see if that existing in yourApps. If it does, i want to take the description property from that application in yourApps and set the description property on the application on myApps to that same value i wanted to see if there was any slick way using lambda expressions (instead of having to have loops and a number of if statements.)

  • Does the order of the columns in a SELECT statement make a difference?

    - by Frank Computer
    This question was inspired by a previous question posted on SO, "Does the order of the WHERE clause make a differnece?". Would it improve a SELECT statement's performance if the the columns used in the WHERE section are placed at the begining of the SELECT statement? example: SELECT customer.id, transaction.id, transaction.efective_date, transaction.a, [...] FROM customer, transaction WHERE customer.id = transaction.id; I do know that limiting the list of columns to only the needed ones in a SELECT statement improves performance as opposed to using SELECT * because the current list is smaller.

  • using different string files in android

    - by boreas
    I'm porting my iPhone app to android and I'm having a problem with the string files now. The app is a translation tool and users can switch the languages, so all the localized strings are in both languages and they are independent from what locale the OS is running. For iOS version I have different files like de.strings, en.strings and fr.strings and so on. For every target with specified language pair I read the strings from the string tables, e.g. for de-fr I will include de.strings and fr.strings in project and set the name of the string tables in the info-list file and read strings from them. In the end I have one project containing different targets (with different info-list files) and all are well configured. I'm intending to do the same on android platform, but Is only one strings.xml allowed per project? How do I set different build target? How do I specify per target which strings.xml it should read?
