  • Retrieving the type of a Collection

    - by nevets1219
    So I have something like the following in Java: private List<SomeType>variable; // ....variable is instantiated as so ... variable = new ArrayList<SomeType>(); // there's also a getter public List<SomeType> getVariable() { /* code */ } What I would like to be able to do is figure out that variable is a collection of SomeType programmatically. I read here that I can determine that from the method getVariable() but is there any way to tell directly from variable? I have been able to retrieve SomeType from the getter method based on the information in the link. I have also been successful in retrieving all the fields of the surrounding class via SurroundingClass.getClass().getDeclaredFields() but this doesn't tell me that it is List<SomeType>.

  • DataSetProvider - DataSet to ClientDataSet

    - by nomad311
    I am trying to take data from a TMSQuery which is connected to my DB and populate a ClientDataSet with some of that data using a DataSetProvider. My problem is that I will need to modify some of this data before it can go into my ClientDataSet. The ClientDataSet has persistent fields that will not match up with the raw DB data. I can't even get a string from the DB into a memo field in ClientDataSet. The ClientDataSet is a part of my data tier so I will need to conform the data from the DB to the ClientDataSet field by field (well most will be able to go right through, but many will require routing and/or conversion). Does anyone have experience with this?

  • How to display unique success messages on jquery form validation

    - by mastah
    Hi guys, hope you can help me on this one, I'm currently using this: jQuery plugin:validation (Homepage) I've been reading related questions here, but this one is the closest get. http://stackoverflow.com/questions/1863448/jquery-validation-on-success from the plugin's documentation http://docs.jquery.com/Plugins/Validation/validate#toption success String, Callback If specified, the error label is displayed to show a valid element. If a String is given, its added as a class to the label. If a Function is given, its called with the label (as a jQuery object) as its only argument. That can be used to add a text like "ok!". Currently I'm only object given to me is the label, and I can only add text to it. Now what I want is to have unique success message. For example: username field will have a success message: 'username okay!' email = 'email seems right' something along those lines, instead of displaying just one generic success message on all the fields. Thanks in advanced :)

  • DTO and mapper generation from Domain Objects

    - by Nicolas
    I have plenty of java domain objects that I need to transform to DTOs. Please, don't start with the anti-pattern thing, the Domain Objects are what they are because of a long history, and I can't modify them (or not too much, see below). So, of course, we've passed the age of doing all that manually. I've looked around, and dozer seems the framework of choice for DTO mapping. But... what I'd really like is this: annotate classes and fields that I want in DTO, and run a tool that would generate the DTOs and the mappers. Does that sound too unreasonable? Does such a tool already exist?

  • MySQL: Blank row in table after LOAD DATA INFILE

    - by Tom
    Hi, I'm uploading a large amount of data from a CSV (I'm doing it via MySQL Workbench): LOAD DATA INFILE 'C:/development/mydoc.csv' INTO TABLE mydatabase.mytable CHARACTER SET utf8 FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"' LINES TERMINATED BY '\r'; However, I'm noticing that it keeps adding an empty line full of nulls/zeros after the last record. I'm guessing it's because of the "LINES TERMINATED" command. However, I need that to load the data in correctly. Is there some way around this / some better SQL to avoid the blank row in the table? Thanks

  • Spring: Inject static member (System.in) via constructor

    - by Julian Lettner
    I wrote some sort of console client for a simple application. To be more flexible, I thought it would be nice to only depend on java.io.Input-/OutputStream, instead of accessing System.in/out directly. I renamed the class ConsoleClient to StreamClient, added setters and made sure that the instance fields are used instead of System.in/out. At the moment my client code looks like this: ApplicationContext appCtx = new ClassPathXmlApplicationContext("..."); StreamClient cc = (StreamClient) appCtx.getBean("streamClient"); cc.setInputStream(System.in); cc.setOutputStream(System.out); cc.run(); // start client Question: Is there a way to move lines 3 and 4 into the Spring configuration (preferably constructor injection)? Thanks for your time.

  • How can I put rows of MySQL data under the appropriate titles using PHP?

    - by sfarbota
    I have the following MySQL table structure: num field company phone website 1 Gas abcd 123456789 abcd.com 2 Water efgh 987654321 efgh.com 3 Water ijkl 321654987 ijkl.com 4 Heat mnop 987654321 mnop.com 5 Gas qrst 123789654 qrst.com ... Is it possible with PHP (maybe using some mixture of GROUP_BY and ORDER_BY) to echo the data to the screen in the following format: Gas: abcd qrst 123456789 123789654 abcd.com qrst.com Water: efgh ijkl 987654321 321654987 efgh.com ijkl.com Heat: mnop 321654987 mnop.com The exact format of it isn't important. I just need for the different rows of data to be listed under the appropriate field with none of the fields repeated. I've been trying to figure this out for a while now, but I'm new to PHP and I can't seem to figure out how to do this, if it's even possible, or if there's a better way to organize my data to make it easier.

  • mysql select query problem

    - by Chocho
    i have a form that has a multiple select drop down. a user can select more than one options in the select. the name of the select is array[]; using php i implode(",",$array) in mysql db, it stores the field as a text in this format "places"= "new york, toronto, london" when i want to display these fields i explode the commas. i am trying to run a report to display the places. here is my select: "select * from mytable where db.places .. userSelectedPlaces" how can i check toronto in lists of "places" that user selected? note "places" in the db might be either just "toronto" or it might be comma separated lists of places like "ny, toronto, london, paris, etc".

  • Is this code thread-safe?

    - by mafutrct
    I've got a class with several properties. On every value update, a Store method is called with stores all fields (in a file). private int _Prop1; public int Prop1 { get { return _Prop1; } set { _Prop1 = value; Store(); } } // more similar properties here... private XmlSerializer _Ser = new ...; private void Store() { lock (_Ser) { using (FileStream fs = new ...) { _Ser.Serialize (fs, this); } } } Is this design thread-safe? (Btw, if you can think of a more appropriate caption, feel free to edit.)

  • Reset UITextField's original placeholder text

    - by Michael
    I'm adding some user feedback mechanism into my app. The user types some comments into a text field and when that editing is done it updates a UITextView. Then when the user hits the submit button and moves on in the app the user may have need to send more feedback from the same form for a different item. I can reset the other fields and labels in the app to their default values when I hide the view, but not the textField (?). How can I reestablish the placeholder text next time the user accesses this view? Your suggestions are humbly appreciated.

  • Simple way to use Foreign Key values for sorting?

    - by Brian Rizzo
    Disclaimer: I jumped to C# 2008 recently and SubSonic 3 (3.0.0.4) at the same time. I haven't used Linq for much of anything in the past. Is there an easy way to use the foreign key display value for sorting, rather than the FK Id (which is numeric)? I've added a new Find method in my ActiveRecord.tt to help with sorting based on a string field name but after doing some testing I realized that even though its working as it should be, I am not handling foreign key fields at all (they are just sorting by their value). Even if I need to change how I am accessing the data it is early enough in the project to do that. Just looking for suggestions.

  • JSF hiding exceptions?

    - by bshacklett
    I have a managed bean for a JSF page which is doing JPA calls in the constructor to populate fields in the bean. I'm having a bit of trouble with another call to persist an entity (to populate data for testing). I'm expecting it to throw some sort of exception since it's not working, but I'm not getting anything. Just of the heck of it I tried the following: Query newQuery = em.createQuery("Bad Syntax"); List newList = newQuery.getResultList(); I'd expect an IllegalArgumentException here since the query string is completely invalid, but the page still loads and I don't see any exceptions anywhere. Am I right in expecting this exception? If so, why am I not seeing it?

  • Add characters to month loop?

    - by JM4
    I currently have a php loop running exactly how I need it with proper validations (in both php and javascript) with one exception, if the month is less than 2 digits, (i.e. 1,2,3,4), I need for a '0' to appear before: 01 - January 02 - February ... 10 - October My code for the loop is currently: <select name="Month"> <option value="">Month</option> <?php for ($i=1; $i<=12; $i++) { echo "<option value='$i'"; if ($fields["Month"] == $i) echo " selected"; echo ">$i</option>"; } ?> </select> any ideas? Also note, this month date is being stored in session, not interested in printing to screen

  • Modeling software for network serialization protocol design

    - by Aurélien Vallée
    Hello, I am currently designing a low level network serialization protocol (in fact, a refinement of an existing protocol). As the work progress, pen and paper documents start to show their limits: i have tons of papers, new and outdated merged together, etc... And i can't show anything to anyone since i describe the protocol using my own notation (a mix of flow chart & C structures). I need a software that would help me to design a network protocol. I should be able to create structures, fields, their sizes, their layout, etc... and the software would generate some nice UMLish diagrams.

  • Please suggest some alternative to Drupal

    - by abovesun
    Drupal propose completely different approach in web development (comparing with RoR like frameworks) and it is extremely good from development speed perspective. For example, it is quite easy to clone 90% of stackoverflow functionality using Drupal. But it has several big drawbacks: it is f''cking slow (100-400 requests per page) db structure very complicated, need at least 2 tables for easy content (entity) type, CCK fields very easy generate tons of new db tables anti-object oriented, rather aspect-oriented bad "view" layer implementation, no strange forward layouts and so on. After all this items I can say I like Drupal, but I would like something same, but more elegant and more object oriented. Probably something like http://drupy.net/ - drupal emulation on the top of django. P.S. I wrote this question not for new holy word flame, just write if you know alternative that uses something similar approach.

  • What should I consider when deploying a new web farm?

    - by tsilb
    My web app has been chugging along just great in Production for years with one App server and one Web server. Now we're moving to a multi-server environment with 2 App and 3 Web servers. I have enough time to make changes before the go-live. As a Developer, what considerations should I take into account from coding, deployment, and architectural/ecosystem management perspectives? Already on my list: Remove tight-coupling between servers Applicable files (i.e. downloadables) stored in IMAGE fields in SQL instead of files on app server Deployment: Take out node out of the farm at a time

  • symfony sfValidatorSchemaCompare and dateformat output problem

    - by Gerbrand
    public function configure() { $this->widgetSchema['start_date'] = new sfWidgetFormInput(); $this->widgetSchema['end_date'] = new sfWidgetFormInput(); $this->validatorSchema->setPostValidator( new sfValidatorOr ( array( new sfValidatorAnd( array (new sfValidatorSchemaCompare('start_date', sfValidatorSchemaCompare::NOT_EQUAL, null), new sfValidatorSchemaCompare('end_date', sfValidatorSchemaCompare::EQUAL, null) )), new sfValidatorSchemaCompare('start_date', sfValidatorSchemaCompare::LESS_THAN_EQUAL, 'end_date', array('throw_global_error' => false), array('invalid' => 'The start date ("%left_field%") must be before the end date ("%right_field%")'))))); } I've got following input dates which I want to check if the end date isn't before the start date: Input: Start = 31/03/10 End= 07/03/10 Output: The start date (2010-03-31) must be before the end date (2010-03-07) Can you in some way change the date output? I need the error message to set the date format the same as the input. Also my input fields are set with the wrong date format when the error appears. Tried several things, but no luck at this moment. Didn't find a solution or information on symfony it self. I'm using symfony version 1.2.11

  • Graphical database monitoring tool for debugging

    - by salle55
    I would love a tool that in real-time showed changes in a set of predefined tables in a graphical way, for example different colors on fields that has changed value, added records, deleted records etc. I don't want a list of all transactions (like SQL Server Profiler), instead a clever visualized more graphical approach where you can get a great overview if you are just monitoring a few tables. I realize the visualization would be hard if there is a lot of transactions against the database, but with monitoring on a few tables and a single session during debugging it would be possible. Does something like this exist? I think it would be great for debugging! Preferably for SQL Server and/or MySQL.

  • SDP media field format

    - by TacB0sS
    Hey, I would like to create a SDP media field with its attributes, and there are a few things I don't understand. I've skimmed and read the relevant RFC and I understand most of what each field means, but what I don't understand is how do I derive from the Audio/Video Format of the JMF, which parameters of the format compose the rtpmap registry entries I need to use. I see many times the fields m=audio 12548 RTP/AVP 0 8 101 a=rtpmap:0 PCMU/8000 a=rtpmap:8 PCMA/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-16 a=silenceSupp:off - - - - a=ptime:20 a=sendrecv these are received from the pbx server I'm connecting to, what do they mean in the terms of the JMF audio format properties. (I do understand these are standard audio format commonly used in telecommunication) UPDATE: I was more wondering about the format parameter '0 8 101' at the end of m=audio 12548 RTP/AVP 0 8 101 Thanks in advance, Adam Zehavi.

  • RESTful web services - best way to return result of an operation?

    - by saille
    I am designing a RESTful API and I would like to know what the most RESTful way is to return details about an operation. E.g. an operation on a resource occurs when some data is POSTed to a URL. HTTP status codes will indicate either success or failure for the operation. But apart from success/failure I need to indicate some other info to the client, such as an ID number. So my question is, should the ID number be returned in an XML document in the response content, or should it be returned in some custom HTTP header fields? Which is more in line with the principles of REST? Or am I free to choose.

  • Is there a good reflection library available for Scala?

    - by Erik Engbrecht
    I'm working on a library that needs reflection, and needs Scala-specific information as opposed to what is available via the standard Java reflection API. Right now I'm using the undocumented code in scalap (the Scala equivalent to javap) and trying to associate the data it provides with Java reflection objects so that I can call methods and such (scalap just parses class files). I found this but there's nothing there... https://github.com/dubochet/scala-reflection ...and I've searched the Scala SVN repo for traces of it and failed to find it there, either (but it could be I just missed it). Does anyone know of a Scala reflection library that provides information similar to what scalap provides but also allows you to call methods, access fields, etc like the Java reflection library?

  • Using set with values from a table

    - by gozzilli
    I'm writing a database of all DVDs I have at home. One of the fields, actors, I would like it to be a set of values from an other table, which is storing actors. So for every film I want to store a list of actors, all of which selected from a list of actors, taken from a different table. Is it possible? How do I do this? It would be a set of foreign keys basically. I'm using a MySQL database for a Django application (python), so any hint in SQL or Python would be much appreciated. I hope the question is clear, many thanks.

  • How to set labels inside textfields for username and password like facebook?

    - by NAVEED
    I have a login form for my website. This login form have two text fields, username and password. Currently I am placing labels(username, password) just before textfields. But now I want to removed these two labels and want to show text(username, password) inside textfield. When user focuses on these textfields then texts should be removed and user can enter his desired username and password. I have also noticed that when user open a login form then font color of text(username, password) populated in textfield(username, password) is of diffent color and when user start typing in that field then previous text is removed and new font color is black. How is it possible?
