  • CodeIgniter's Scaffolding not working

    - by 01010011
    Hi, I keep getting a 404 Page Not Found whenever I try to access CodeIgniter's Scaffolding page in my browser, like so: localhost/codeignitor/index.php/blog/scaffolding/mysecretword I can access localhost/codeignitor/index.php/blog just fine. I followed CodeIgnitor's instructions in their "Create a blog in 20 minutes" by storing my database settings in the database.php file; and automatically connecting to the database by inserting "database" in the core array of the autoload.php; and I've added both parent::Controller(); and $this-load-scaffolding('myTableName') to blog's constructor. It still gives me this 404. Any suggestions?

  • How to develop JSP/Servlets Web App using MVC pattern?

    - by A.S al-shammari
    I'm developing a JSP/Servlets web app (no frameworks). I want to use MVC pattern. I designed my project like this : Controller :a servlet that reads a request, extracts the values,communicates with model objects and gives information to a JSP page. View : JSP Pages. Model : Java Classes / Java Beans .. etc . The problem : Index.jsp is the starting point (default page) in my web site. So, the Index.jsp becomes the controller to parse the request! .For example , the following request : index.jsp?section=article&id=10 parsed in index.jsp as following : <div class="midcol"> <!-- Which section? --> <%String fileName = request.getParameter("section"); if (fileName == null) { fileName = "WEB-INF/jspf/frontpage.jsp"; } else { fileName = "WEB-INF/jspf/" + fileName + ".jsp"; } %> <jsp:include page='<%= fileName%>' /> </div> Here, I can't force the servlet to be a controller .. because the index.jsp is the controller here since it's the starting point! Is there any solution to forward the request from index.jsp to the servlet and then go back to index.jsp ? Or any solution that achieves the MVC goal - the servlet should be the controller - ? I'm thinking of making a FrontPageController servlet as default page instead of index.jsp ! but I don't know if it's a perfect idea ?!

  • jQuery event handling with .live() problem with setInterval and clearInterval

    - by Kyle Lafkoff
    jQuery 1.4.2: I have an image. When the mouseover event is triggered, a function is executed that runs a loop to load several images. On the contrary, the mouseout event needs to set the image back to a predetermined image and no longer have the loop executing. These are only for the images with class "thumb": $("img.thumb").live("mouseover mouseout", function(event) { var foo = $(this).attr('id'); var wait; var i=0; var image = document.getElementById(foo); if (event.type == 'mouseover') { function incrementimage() { i++; image.src = 'http://example.com/images/file_'+i+'.jpg'; if(i==30) {i=0;} } wait = setInterval(incrementimage,500); } else if (event.type == 'mouseout') { clearInterval (wait); image.src = 'http://example.com/images/default.jpg'; } return false; }); When I mouseout, the image is set to the default.jpg but the browser continues to loop though the images. It will never stop. Can someone hit me with some knowledge? Thanks.

  • How to make an entity out of a join table without primary key

    - by tputkonen
    I'm trying to generate JPA entities out of an existing database having an "interesting" design. Database has a table called UserSet, which can have links to several other UserSets. There is a one to many relation between UserSets and LinkedUserSets. LinkedUserSets also has one to one relation to UserSets. I tried to generate a JPA Entity out of the database structure using Dali JPA Tools. The resulting entity Linkeduserset misses @Id or @EmbeddedId annotation and thus failes to compile. As the resulting entity contains only two @JoinColumns (which cannot be marked as @Id), I have not so far found a way around this issue. Database structure can not be modified in any way. Is there a way to overcome this somehow? Relevant pars of create table statements: CREATE TABLE `LinkedUserSets` ( `UsrSetID` INT(11) NOT NULL DEFAULT '0' , `ChildID` INT(11) NOT NULL DEFAULT '0' , CONSTRAINT `fk_LinkedUserSets_UserSet1` FOREIGN KEY (`UsrSetID` ) REFERENCES `UserSet` (`UsrSetID` )); CREATE TABLE `UserSet` ( `UsrSetID` INT(11) NOT NULL AUTO_INCREMENT , PRIMARY KEY (`UsrSetID`), CONSTRAINT `fk_UserSet_LinkedUserSets1` FOREIGN KEY (`UsrSetID` ) REFERENCES `LinkedUserSets` (`ChildID` )); Generated entities: @Entity @Table(name="linkedusersets") public class Linkeduserset { //bi-directional many-to-one association to Userset @ManyToOne @JoinColumn(name="UsrSetID") private Userset userset1; //bi-directional one-to-one association to Userset @OneToOne @JoinColumn(name="ChildID") private Userset userset2; } @Entity @Table(name="userset") public class Userset { private static final long serialVersionUID = 1L; @Id @Column(name="UsrSetID") private int jngSetID; //bi-directional many-to-one association to Linkeduserset @OneToMany(mappedBy="userset1") private Set<Linkeduserset> linkedusersets; //bi-directional one-to-one association to Linkeduserset @OneToOne(mappedBy="userset2") private Linkeduserset linkeduserset; } Error message: Entity "Linkeduserset" has no Id or EmbeddedId

  • Select box is not working properly after including google custom search box in web page

    - by Vinay
    I have got a select box and google custom search box in a page, when i choose a option from select box and navigate away from the page and again if i come back to the same page the option will not be selected (violates the default functionality of select box), The code is below <script src="https://www.google.com/jsapi" type="text/javascript"></script> <script type="text/javascript"> google.load('search', '1', {language : 'en'}); google.setOnLoadCallback(function() { var customSearchControl = new google.search.CustomSearchControl('004920913350056953771:kpkclvhujzk'); customSearchControl.setResultSetSize(google.search.Search.FILTERED_CSE_RESULTSET); var options = new google.search.DrawOptions(); options.setAutoComplete(true); options.enableSearchboxOnly("<?=$homeurl?>my_results.php", "query"); customSearchControl.draw('cse-search-form', options); }, true); </script> <select multiple="yes"> <option>1</option> <option>2</option> </select> If i remove the custom search script, the select box selected option will be retained even after navigating away from the page. (default functionality) Its working fine in chrome, IE but not in Firefox. Is there any solution for this, so that select box must work fine even in the presence of search box, but the order must be same 1) Search box 2)Select Box

  • How can I get the plain-text content of a Google Doc via Google Doc API in Silverlight?

    - by Edward Tanguay
    I would like to use the Google Doc API to retrieve the plain-text content of a Google Doc document (not a spreadsheet) via the Google Docs API. In the documentation I can find information about accessing Spreadsheets and how to "create/upload/copy" documents: http://code.google.com/apis/documents/overview.html Does anyone have a C# code example to do this in Silverlight, something like this: //PSEUDOCODE: WebClientGoogleDoc proxy = new WebClientGoogleDoc (); proxy.DownloadStringCompleted += new DownloadStringCompletedEventHandler(proxy_DownloadStringCompleted); proxy.DownloadProgressChanged += new DownloadProgressChangedEventHandler(proxy_DownloadProgressChanged); proxy.DownloadStringAsyncWithGoogleDocId("dc7gj86r_20dn2csqg3");

  • Slow retrieval of data in SQLITE takes a long using ContentProvider

    - by Arlyn
    I have an application in Android (running 4.0.3) that stores a lot of data in Table A. Table A resides in SQLite Database. I am using a ContentProvider as an abstraction layer above the database. Lots of data here means almost 80,000 records per month. Table A is structured like this: String SQL_CREATE_TABLE = "CREATE TABLE IF NOT EXISTS " + TABLE_A + " ( " + COLUMN_ID + " INTEGER PRIMARY KEY NOT NULL" + "," + COLUMN_GROUPNO + " INTEGER NOT NULL DEFAULT(0)" + "," + COLUMN_TIMESTAMP + " DATETIME UNIQUE NOT NULL" + "," + COLUMN_TAG + " TEXT" + "," + COLUMN_VALUE + " REAL NOT NULL" + "," + COLUMN_DEVICEID + " TEXT NOT NULL" + "," + COLUMN_NEW + " NUMERIC NOT NULL DEFAULT(1)" + " )"; Here is the index statement: String SQL_CREATE_INDEX_TIMESTAMP = "CREATE INDEX IF NOT EXISTS " + TABLE_A + "_" + COLUMN_TIMESTAMP + " ON " + TABLE_A + " (" + COLUMN_TIMESTAMP + ") "; I have defined the columns as well as the table name as String Constants. I am already experiencing significant slow down when retrieving this data from Table A. The problem is that when I retrieve data from this table, I first put it in an ArrayList and then I display it. Obviously, this is possibly the wrong way of doing things. I am trying to find a better way to approach this problem using a ContentProvider. But this is not the problem that bothers me. The problem is for some reason, it takes a lot longer to retrieve data from other tables which have only upto 12 records maximum. I see this delay increase as the number of records in Table A increase. This does not make any sense. I can understand the delay if I retrieve data from Table A, but why the delay in retrieving data from other tables. To clarify, I do not experience this delay if Table A is empty or has less than 3000 records. What could be the problem?

  • How do ASP.NET MVC Routes work?

    - by Pure.Krome
    Hi folks, imagine i have the following route setup... public static void RegisterRoutes(RouteCollection routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute( "Default", "{controller}/{action}/{id}", new { controller = "Home", action = "Index", id = "" } ); // Added custom route here! routes.MapRoute( "CatchAll", "{*catchall}," new { controller = "Error", action = "NotFound" } ); } nothing new - that's the default ASP.NET MVC1 RegisterRoutes method, with one custom route added. Now, if I goto the following url, i get a 404... http://whatever/Home/MissingActionMethod So there's no ActionMethod called MissingActionMethod in the HomeController. So, does this mean, if i goto the 1st route defined, above .. and fail to find an action .. do I then come back and try the second route? rinse-repeat? Or once i match a route, i then try and execute that route .. and if i fail (ie, find the action is missing) .. then .. bad luck? boomski? cheers!

  • How to efficiently show many Images? (iPhone programming)

    - by Thomas
    In my application I needed something like a particle system so I did the following: While the application initializes I load a UIImage laserImage = [UIImage imageNamed:@"laser.png"]; UIImage *laserImage is declared in the Interface of my Controller. Now every time I need a new particle this code makes one: // add new Laserimage UIImageView *newLaser = [[UIImageView alloc] initWithImage:laserImage]; [newLaser setTag:[model.lasers count]-9]; [newLaser setBounds:CGRectMake(0, 0, 17, 1)]; [newLaser setOpaque:YES]; [self.view addSubview:newLaser]; [newLaser release]; Please notice that the images are only 17px * 1px small and model.lasers is a internal array to do all the calculating seperated from graphical output. So in my main drawing loop I set all the UIImageView's positions to the calculated positions in my model.lasers array: for (int i = 0; i < [model.lasers count]; i++) { [[self.view viewWithTag:i+10] setCenter:[[model.lasers objectAtIndex:i] pos]]; } I incremented the tags by 10 because the default is 0 and I don't want to move all the views with the default tag. So the animation looks fine with about 10 - 20 images but really gets slow when working with about 60 images. So my question is: Is there any way to optimize this without starting over in OpenGl ES? Thank you very much and sorry for my english! Greetings from Germany, Thomas

  • How to install Eclipse + PHP Development Tools (PDT) + Debugger on Mac in The Year 2010

    - by aphex5
    I had a lot of trouble installing Eclipse and PDT on my system. It took two days, largely because all the tutorials I could find were out of date (written in 2008, it's 2010 now) and various steps they included were no longer necessary, broken, or irrelevant. I wanted to write my process here so it could be improved upon (via wiki) as time goes on. Install Eclipse without PHP plugin ("Eclipse Classic"). This will give you a complete Eclipse, which I find preferable, as the UI is more fleshed out (e.g. you get a default list of Perspectives, which helps you understand what Perspectives are.) Install PDT SDK with the Help Install New Software menu item. You'd think you'd be done here, but if you try to run something, it'll fail complaining of not having a debugger. Install the Zend Debugger. It'll fail if you try to use the Install New Software option, as many tutorials suggest ("No repository found containing osgi.bundle.org.zend.php.debug.debugger.5.3.7.v20091116".) Instead, download it from http://www.zend.com/en/community/pdt, and manually copy the features/ and plugins/ directory into your Eclipse install (these instructions are not written anywhere). Restart Eclipse Monkey with preferences for a while -- if you followed a previous tutorial and tried to manually add your php executable to Eclipse prefs (/usr/bin/php), remove it (PHP PHP Executables). Set one of the Zend Debugger executables to the default. If you've already tried to execute a .php file, remove the existing "Run" profile you (maybe weren't aware that you) created (Run Debug Configurations...). Eclipse works! You should be able to run a .php file as a script just fine.

  • std::locale breakage on MacOS 10.6 with LANG=en_US.UTF-8

    - by fixermark
    I have a C++ application that I am porting to MacOSX (specifically, 10.6). The app makes heavy use of the C++ standard library and boost. I recently observed some breakage in the app that I'm having difficulty understanding. Basically, the boost filesystem library throws a runtime exception when the program runs. With a bit of debugging and googling, I've reduced the offending call to the following minimal program: #include <locale> int main ( int argc, char *argv [] ) { std::locale::global(std::locale("")); return 0; } This program fails when I run this through g++ and execute the resulting program in an environment where LANG=en_US.UTF-8 is set (which on my computer is part of the default bash session when I create a new console window). Clearing the environment variable (setenv LANG=) allows the program to run without issues. But I'm surprised I'm seeing this breakage in the default configuration. My questions are: Is this expected behavior for this code on MacOS 10.6? What would a proper workaround be? I can't really re-write the function because the version of the boost libraries we are using executes this statement internally as part of the filesystem library. For completeness, I should point out that the program from which this code was synthesized crashes when launched via the 'open' command (or from the Finder) but not when Xcode runs the program in Debug mode. edit The error given by the above code on 10.6.1 is: $ ./locale terminate called after throwing an instance of 'std::runtime_error' what(): locale::facet::_S_create_c_locale name not valid Abort trap

  • design suggestion for a message decoder in delphi

    - by stanleyxu2005
    Hi All, I want to implement a RPC module. Different requests are encoded as JSON objects. They will be decoded and then be handled by a request handler. At last a corresponding response will be returned. The demo code looks as follows: type IRequestHandler = interface function Handle(const Request: TAaaRequest): TResponse; function Handle(const Request: TBbbRequest): TResponse; end; TDecoder = class class function Decode(const Json: TJsonObject; const RequestHandler: IRequestHandler): TResponse; end; class function TDecoder.Decode(const Json: TJsonObject; const RequestHandler: IRequestHandler): TResponse; var Method: string; Request: TObject; begin Method := Json['method'].AsString; if (Method = TAaaRequest.ClassName) then begin Request := TAaaRequest.FromJSON(Json); // Casted as TObject if Request <> nil then begin Result := RequestHandler.Handle(TAaaRequest(Request)); Request.Free; end; end else if (Method = TBbbRequest.ClassName) then begin Request := TBbbRequest.FromJSON(Json); // Casted as TObject if Request <> nil then begin Result := RequestHandler.Handle(TBbbRequest(Request)); Request.Free; end; end else Result := CreateErrorResponse('Unknown method: ' + Json.ToString); end; According to the code, the handling of different request types are very similar. If I have 100 different request types, I have to copy and paste the above code block 100 times. This is not clever. I am looking for a better way to do the same logic. My imagination is as follows: TDecoder = class private FRequestTypes: TDictionary<string, TClassInfo>; // Does this work? public constructor Create; destructor Destroy; override; function Decode(const Json: TJsonObject; const RequestHandler: IRequestHandler): TResponse; end; constructor TDecoder.Create; begin FRequestTypes := TDictionary<string, TClassInfo>.Create; FRequestTypes.Add(TAaaRequest.ClassName, TAaaRequest); // Does this work? FRequestTypes.Add(TBbbRequest.ClassName, TBbbRequest); end; destructor TDecoder.Destroy; begin FRequestTypes.Free; inherited; end; function TDecoder.Decode(const Json: TJsonObject; const RequestHandler: IRequestHandler): TResponse; var Method: string; Info: TClassInfo; Request: TObject; begin Method := Json['method'].AsString; if FRequestTypes.ContainsKey(Method) then begin // An universal way Info := FRequestTypes[Method]; Request := Info.FromJSON(Json); // Casted as TObject if Request <> nil then begin Result := RequestHandler.Handle(Info(Request)); // Casted to corresponding class type (e.g. TAaaRequest or TBbbRequest) Request.Free; end; end else Result := CreateErrorResponse('Unknown method: ' + Json.ToString); end; I do not know, if I can write an universal way to handle a great number of different request types. Development environment Delphi 2010. Any hint is appreciated.

  • PostgreSQL - Error: SQL state: XX000.

    - by rob
    I have a table in Postgres that looks like this: CREATE TABLE "Population" ( "Id" bigint NOT NULL DEFAULT nextval('"population_Id_seq"'::regclass), "Name" character varying(255) NOT NULL, "Description" character varying(1024), "IsVisible" boolean NOT NULL CONSTRAINT "pk_Population" PRIMARY KEY ("Id") ) WITH ( OIDS=FALSE ); And a select function that looks like this: CREATE OR REPLACE FUNCTION "Population_SelectAll"() RETURNS SETOF "Population" AS $BODY$select "Id", "Name", "Description", "IsVisible" from "Population"; $BODY$ LANGUAGE 'sql' STABLE COST 100 Calling the select function returns all the rows in the table as expected. I have a need to add a couple of columns to the table (both of which are foreign keys to other tables in the database). This gives me a new table def as follows: CREATE TABLE "Population" ( "Id" bigint NOT NULL DEFAULT nextval('"population_Id_seq"'::regclass), "Name" character varying(255) NOT NULL, "Description" character varying(1024), "IsVisible" boolean NOT NULL, "DefaultSpeciesId" bigint NOT NULL, "DefaultEcotypeId" bigint NOT NULL, CONSTRAINT "pk_Population" PRIMARY KEY ("Id"), CONSTRAINT "fk_Population_DefaultEcotypeId" FOREIGN KEY ("DefaultEcotypeId") REFERENCES "Ecotype" ("Id") MATCH SIMPLE ON UPDATE NO ACTION ON DELETE NO ACTION, CONSTRAINT "fk_Population_DefaultSpeciesId" FOREIGN KEY ("DefaultSpeciesId") REFERENCES "Species" ("Id") MATCH SIMPLE ON UPDATE NO ACTION ON DELETE NO ACTION ) WITH ( OIDS=FALSE ); and function: CREATE OR REPLACE FUNCTION "Population_SelectAll"() RETURNS SETOF "Population" AS $BODY$select "Id", "Name", "Description", "IsVisible", "DefaultSpeciesId", "DefaultEcotypeId" from "Population"; $BODY$ LANGUAGE 'sql' STABLE COST 100 ROWS 1000; Calling the function after these changes results in the following error message: ERROR: could not find attribute 11 in subquery targetlist SQL state: XX000 What is causing this error and how do I fix it? I have tried to drop and recreate the columns and function - but the same error occurs. Platform is PostgreSQL 8.4 running on Windows Server. Thanks.

Copying the war as an expanded directory helped. Still, I am wondering how to configure Jetty to copy everything. And, with mvn jetty:run I get the same error. Thanks, Ondra
