  • Eclipse warning: "<methodName> has non-API return type <parameterizedType>"

    - by Tenner
    My co-worker and I have come across this warning message a couple times recently. For the below code: package com.mycompany.product.data; import com.mycompany.product.dao.GenericDAO; public abstract class EntityBean { public abstract GenericDAO<Object, Long> getDAO(); // ^^^^^^ <-- WARNING OCCURS HERE } the warning appears in the listed spot as EntityBean.getDAO() has non-API return type GenericDAO<T, ID> A Google search for "has non-API return type" only shows instances where this message appears in problem lists. I.e., there's no public explanation for it. What does this mean? We can create a usage problem filter in Eclipse to make the message go away, but we don't want to do this if our usage is a legitimate problem. Thanks!

  • loaderInfo null inside creationComplete handler function

    - by Thiago
    Hi, I've coded this small snippet to show what I'm not understanding: <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" creationComplete="init()"> <mx:Script> public function init():void { txtName.text = this.loaderInfo.toString(); } </mx:Script> <mx:TextInput x="50" y="10" id="txtName"/> </mx:Application> I'm getting the following error: TypeError: Error #1009: Cannot access a property or method of a null object reference. at Teste/init()[C:\Lucas\flex\AppName\src\Teste.mxml:5] at Teste/___Teste_Application1_creationComplete()[C:\User\flex\CornetaRecorder\src\Teste.mxml:2] at flash.events::EventDispatcher/dispatchEventFunction() at flash.events::EventDispatcher/dispatchEvent() at mx.core::UIComponent/dispatchEvent()[C:\autobuild\3.2.0\frameworks\projects\framework\src\mx\core\UIComponent.as:9298] at mx.core::UIComponent/set initialized()[C:\autobuild\3.2.0\frameworks\projects\framework\src\mx\core\UIComponent.as:1169] at mx.managers::LayoutManager/doPhasedInstantiation()[C:\autobuild\3.2.0\frameworks\projects\framework\src\mx\managers\LayoutManager.as:718] at Function/http://adobe.com/AS3/2006/builtin::apply() at mx.core::UIComponent/callLaterDispatcher2()[C:\autobuild\3.2.0\frameworks\projects\framework\src\mx\core\UIComponent.as:8628] at mx.core::UIComponent/callLaterDispatcher()[C:\autobuild\3.2.0\frameworks\projects\framework\src\mx\core\UIComponent.as:8568] Shouldn't I be able to read loaderInfo inside the creationComplete handler?

  • as3crypto PEM.readRSAPublicKey returns null

    - by www.jefferyfernandez.id.au
    I am trying to implement a bit of encryption in my Air application while communication with a PHP backend server. For this purpose I am using as3crypto library and I can't read the public key to make the encryption possible. Here is my action script code: var rsa:RSAKey = PEM.readRSAPublicKey(this.readApplicationFileContents('server.crt')); if ( rsa ) { var encodeSource:ByteArray = Hex.toArray(Hex.fromString("Hello World")); var encodeDestination:ByteArray = new ByteArray; var encodeDestination2:ByteArray = new ByteArray; rsa.encrypt(encodeSource, encodeDestination, encodeSource.length) rsa.decrypt(encodeDestination, encodeDestination2, encodeDestination.length); trace(encodeDestination2.toString()); } private function readApplicationFileContents(filePath:String):String { var fileObject:File = File.applicationDirectory.resolvePath(filePath); var fileStream:FileStream = new FileStream(); fileStream.open(fileObject, FileMode.READ); var fileContents:String = fileStream.readUTFBytes(fileStream.bytesAvailable); return(fileContents); } readApplicationFileContents function returns the proper certificate contents as a string. But rsa variable always returns null. It would have been easier if I was able to compile the as3crypto library so I can debug through the source, but I can't get the library to compile and can't find any instructions to do the same. Anyone have a clue what's wrong? PS. Sorry first time poster and I can't seem to get the syntax highlighting right. Must be Chrome is not working well with the editor.

  • TypeError: Error #1009 - (Null reference error) With Flash.

    - by Wind Chimez
    I am not an expert in flash, but i do work with AS and tweak Flash projects , though not having deep expertise in it. Currently i need to revamp a flash website done by one another guy, and the code base given to me, upon execution is throwing the following error. "--- TypeError: Error #1009: Cannot access a property or method of a null object reference. at NewSite_fla::MainTimeline/__setProp_ContactOutP1_ContactOut_Contents_0() at NewSite_fla::MainTimeline/frame1() --" The structure of the project is like, it has the different sections split into different movie clips. There is no single main timeline, but click actions on different areas of seperate movie clips will take them between one another. All the AS logic of event handling are written inline in FLA , no seperate Document class exists. Preloader Movie clip is the first one getting loaded. As i understood the error is getting thrown initially itself, and it is not happening due to any Action script logic written inline, because it is throwing error even before hitting the first inline AS code. I am not able to figure Out what exactly it causing the problem, or where to resolve it. I setup the stuff online, for reference if anybody want to take a look at it, and here is the link.You need to have flash debugger turned ON in your browser, if need to see the exception getting triggered. http://tinyurl.com/2alvlfx I really got stuck at this point. Any help will be great.I had not seen the particular solution i am looking for anywhere yet, though Error #1009 is common.

  • Trying to use Rhino, getEngineByName("JavaScript") returns null in OpenJDK 7

    - by Yuval
    When I run the following piece of code, the engine variable is set to null when I'm using OepnJDK 7 (java-7-openjdk-i386). import javax.script.ScriptEngine; import javax.script.ScriptEngineManager; import javax.script.ScriptException; public class TestRhino { /** * @param args */ public static void main(String[] args) { // TODO Auto-generated method stub ScriptEngineManager factory = new ScriptEngineManager(); ScriptEngine engine = factory.getEngineByName("JavaScript"); try { System.out.println(engine.eval("1+1")); } catch (ScriptException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } It runs fine with java-6-openjdk and Oracle's jre1.7.0. Any idea why? I'm using Ubuntu 11.10. All JVMs are installed under /usr/lib/jvm. I noticed OpenJDK 7 has a different directory structure. Perhaps something is not installed right? $ locate rhino.jar /usr/lib/jvm/java-6-openjdk/jre/lib/rhino.jar /usr/lib/jvm/java-7-openjdk-common/jre/lib/rhino.jar /usr/lib/jvm/java-7-openjdk-i386/jre/lib/rhino.jar Edit Since ScriptEngineManager uses a ServiceProvider to find the available script engines, I snooped around resources.jar's META-INF/services. I noticed that in OpenJDK 6, resources.jar has a META-INF/services/javax.script.ScriptEngineFactory entry which is missing from OpenJDK 7. Any idea why? I suspect this is a bug? Here is the contents of that entry (from OpenJDK 6): #script engines supported com.sun.script.javascript.RhinoScriptEngineFactory #javascript Another edit Apparently, according to this thread, the code simply isn't there, perhaps because of merging issues between Sun and Mozilla code. I still don't understand why it was present in OpenJDK 6 and not 7. The class com.sun.script.javascript.RhinoScriptEngineFactory exists in 6's rt.jar but not in 7's. If it was not meant to be included, why is there a OpenJDK 7 rhino.jar then; and why is the source still in the OpenJDK source tree (here)?

  • Passing a non-iterable to list.extend ()

    - by JS
    Hello, I am creating a public method to allow callers to write values to a device, call it write_vals() for example. Since these values will by typed live, I would like to simplify the user's life by allowing them type in either a list or a single value, depending on how many values they need to write. For example: write_to_device([1,2,3]) or write_to_device(1) My function would like to work with a flat list, so I tried to be clever and code something like this: input_list = [] input_list.extend( input_val ) This works swimmingly when the user inputs a list, but fails miserably when the user inputs a single integer: TypeError: 'int' object is not iterable Using list.append() would create a nested list when a list was passed in, which would be an additional hassle to flatten. Checking the type of the object passed in seems clumsy and non-pythonic and wishing that list.extend() would accept non-iterables has gotten me nowhere. So has trying a variety of other coding methods. Suggestions (coding-related only, please) would be greatly appreciated.

  • Generate links for routes with non-parameter url segments on ASP.NET MVC 2

    - by spapaseit
    I have a route defined with several hardcoded (non-parameter) segments: routes.MapRoute(null, "suggestion/list/by/{tag}", new { controller = "Suggestion", action = "List", tag = UrlParameter.Optional }); Suppose I'm in the Index view of SuggestionController, which has a Suggestion object for Model, how can I create a link that matches that route? I'd rather use one of the provided helpers and keep the route name as null in order to avoid hard-coding to much on my views, but I can't figure out how to user these non-parameter segments in Html.ActionLink or RouteLink methods. I've even tried to render the link using plain ol' html <a href="/suggestion/list/by/<%=Model.Tag %>"><%=Model.Tag %></a> but this somehow didn't match the route either. There's probably a very simple solution and I might be over-complicating things in mi mind, but I'm at a loss. Any ideas? Thanks in advance.

  • FLEX: the custom component is still a Null Object when I invoke its method

    - by Patrick
    Hi, I've created a custom component in Flex, and I've created it from the main application with actionscript. Successively I invoke its "setName" method to pass a String. I get the following run-time error (occurring only if I use the setName method): TypeError: Error #1009: Cannot access a property or method of a null object reference. I guess I get it because I'm calling to newUser.setName method from main application before the component is completely created. How can I ask actionscript to "wait" until when the component is created to call the method ? Should I create an event listener in the main application waiting for it ? I would prefer to avoid it if possible. Here is the code: Main app ... newUser = new userComp(); //newUser.setName("name"); Component: <?xml version="1.0" encoding="utf-8"?> <mx:VBox xmlns:mx="http://www.adobe.com/2006/mxml" width="100" height="200" > <mx:Script> <![CDATA[ public function setName(name:String):void { username.text = name; } public function setTags(Tags:String):void { } ]]> </mx:Script> <mx:HBox id="tagsPopup" visible="false"> <mx:LinkButton label="Tag1" /> <mx:LinkButton label="Tag2" /> <mx:LinkButton label="Tag3" /> </mx:HBox> <mx:Image source="@Embed(source='../icons/userIcon.png')"/> <mx:Label id="username" text="Nickname" visible="false"/> </mx:VBox> thanks

  • Using persistent and non-persistent connection together in a PHP MySQL app

    - by cappuccino
    There are parts of my app where a persistent connection is required, in particular the parts where every hour maybe 30,000 select requests are made by many different users, this is causing my mysql server to max out on the 100 connection limit, and i really don't want to increase it since 100 connections already seems like alot. So for the parts of the application where reading and selecting is the case I want to switch to persistent connections. The other parts where data is being modified is usually done through a transaction, and the general rule is never to use persistent connections for transactions according to the php documentation. So I would like to keep this on non-persistent connections. My question is, am i able to use persistent and non-persistent connections together in the same app, the same script etc? I am using PHP 5.2+, MySQL 5+ (InnoDB tables) and the Zend Framework 10.6+

  • How to print non-ASCII characters in Python

    - by Roman
    I have a problem when I'm printing (or writing to a file) the non-ASCII characters in Python. I've resolved it by overriding the str method in my own objects, and making "x.encode('utf-8')" inside it, where x is a property inside the object. But, if I receive a third-party object, and I make "str(object)", and this object has a non-ASCII character inside, it will fail. So the question is: is there any way to tell the str method that the object has an UTF-8 codification, generically? I'm working with Python 2.5.4.

  • Passing Activity to non-activity object properly

    - by rayman
    In my app ive got a non-activity object which it's role is being a manager class. many times i need to pass "source activity" to methods as parameter to that manager class in order to make some operations on that activity. for exaple let's assume we have MyActivity which gotta do some toast. so i have this manager class called MyManager, and i have this method in it raiseToast(Activity sourceActivity) { Toast.makeText(sourceActivity, demo, Toast.LENGTH_LONG).show(); } and from Myactivity class we calling that method this way: MyManager manager=new MyManager(); manager.raitetoast(MyActivity.this); it works fine. what I'm asking here, is this a proper way to pass an Activity as parameter to a non-activity object? I'm having a memory leaks on real device(not the emulator), I wonder if this could also causing any reason for that? Thanks Idan.

  • How to make Spring accept non-void setters?

    - by Chris
    Hi, I have an API which I am turning into an internal DSL. As such, most methods in my PoJos return a reference to this so that I can chain methods together declaratively as such (syntactic sugar). myComponent .setID("MyId") .setProperty("One","1") .setProperty("Two","2") .setAssociation(anotherComponent) .execute(); My API does not depend on Spring but I wish to make it 'Spring-Friendly' by being PoJo friendly with zero argument constructors, getters and setters. The problem is that Spring seems to not detect my setter methods when I have a non-void return type. The return type of this is very convenient when chaining together my commands so I don't want to destroy my programmatic API just be to compatible with Spring injection. Is there a setting in Spring to allow me to use non-void setters? Chris

  • Modern, Non-trivial, Pygame Tutorials?

    - by Gregg Lind
    What are some 'good', non-trivial Pygame tutorials? I realize good is relative. As an example, a good one (to me) is the one that describes how to use pygame.camera. It's recent uses a modern PyGame (1.9) non-trivial, in that it shows how to use it the module for a real application. I'd like to find others. A lot of the ones on the Pygame site are from 1.3 era or earlier! Info on related projects, like Gloss is welcome as well. (If your answer is "read the source of some pygame games", please link to the source of particular ones and note what is good about them)

  • Connect to an elevated COM server from a non-elevated process

    - by JS Bangs
    We have a program which launches a child process that hosts a local COM server, which for various reasons must be launched elevated. Everything works fine so long as both the parent and the child process are elevated. However, we also want to run when the parent process is non-elevated. Launching the child process results in a UAC dialog (which is acceptable), and the child appears to start correctly and successfully calls CoRegisterClassObject. However, the parent process gets REGDB_E_CLASSNOTREG when calling CoCreateInstance with the same CLSID. I assume this is some sort of permissions issue. How can I register my class in the elevated server to allow it to be called from a non-elevated process.

  • value of Identity column returning null when retrieved by value in dataGridView

    - by Raven Dreamer
    Greetings. I'm working on a windows forms application that interacts with a previously created SQL database. Specifically, I'm working on implementing an "UPDATE" query. for (int i = 0; i < dataGridView1.RowCount; i++) { string firstName = (string)dataGridView1.Rows[i].Cells[0].Value; string lastName = (string)dataGridView1.Rows[i].Cells[1].Value; string phoneNo = (string)dataGridView1.Rows[i].Cells[2].Value; short idVal = (short)dataGridView1.Rows[i].Cells[3].Value; this.contactInfoTableAdapter.UpdateQuery(firstName, lastName, phoneNo, idVal); } The dataGridView has 4 columns, First Name, Last Name, Phone Number, and ID (which was created as an identity column when I initially formed the table in SQL). When I try to run this code, the three strings are returned properly, but dataGridView1.Rows[i].Cells[3].Value is returning "null". I'm guessing this is because it was created as an identity column rather than a normal column. What's a better way to retrieve the relevant ID value for my UpdateQuery?

  • SIFR Newbie: font display problem in non-flash browsers

    - by bullquartz
    Hi, I'm wondering if someone can help me with this as I'm fairly new to siFR and think there is something essential i'm not comprehending in the documentation. I'm having success using siFR 3 (r436) to render fonts and it's working just how I want. However if I turn flash off in any browser the original (no longer rendered) html text displays very badly indeed. I thought that in any non-flash browser my inital stylesheet would be referred to and not siFR.css and I would be able to adjust the html text as a seperate entity. I think i probably developed this bad idea because I remember in earlier siFR versions you had to mess around alot with stylings on the original stylesheet + the sifr-config so you would get corresponding line heights/widths etc between the html and rendered font. (i realise that siFR 3 renders the flash in a different way) So it seems that siFR.css controls both the non-flash text and the rendered font. Anyway my essential noob questions is: how do i get the the original html text to have the same dimensions as the rendered font? thanks for you help

  • entity framework - getting null exception using foreign key

    - by Nick
    Having some trouble with what should be a very simple scenario. For example purposes, I have two tables: -Users -Comments There is a one-to-many relationship set up for this; there is a foreign key from Comments.CommentorID to Users.UserID. When I do the LINQ query and try to bind to a DataList, I get a null exception. Here is the code: FKMModel.FKMEntities ctx = new FKMModel.FKMEntities(); IQueryable<Comment> CommentQuery = from x in ctx.Comment where x.SiteID == 101 select x; List<Comment> Comments = CommentQuery.ToList(); dl_MajorComments.DataSource = Comments; dl_MajorComments.DataBind(); In the ASPX page, I have the following as an ItemTemplate (I simplified it and took out the styling, etc, for purposes of posting here since it's irrelevant): <div> <%# ((FKMModel.Comment)Container.DataItem).FKMUser.Username %> <%# ((FKMModel.Comment)Container.DataItem).CommentDate.Value.ToShortDateString() %> <%# ((FKMModel.Comment)Container.DataItem).CommentTime %> </div> The exception occurs on the first binding (FKMUser.Username). Since the foreign key is set up, I should have no problem accessing any properties from the Users table. Intellisense set up the FKMUser navigation property and it knows the properties of that foreign table. What is going on here??? Thanks, Nick

  • how to iterate over non-English file names in PHP

    I have a directory which contains several files, many of which has non-english name. I am using PHP in Windows 7. I want to list the filename and their content using PHP. Currently I am using DirectoryIterator and file_get_contents. This works for English files names but not for non-English (chinese) file names. For example, I have filenames like "?? ?? ?????????.eml", "hello ??????.eml". DirectoryIterator is not able to get the filename using ->getFilename() file_get_contents is also not able to open even if I hard code the filename in its parameter. How can I do it?

  • [C++]Advantage of using a static member function instead of an equivalent non-static member function

    - by jonathanasdf
    I was wondering whether there's any advantages to using a static member function when there is a non-static equivalent. Will it result in faster execution (because of not having to care about all of the member variables), or maybe less use of memory (because of not being included in all instances)? Basically, the function I'm looking at is an utility function to rotate an integer array representing pixel colours an arbitrary number of degrees around an arbitrary centre point. It is placed in my abstract Bullet base class, since only the bullets will be using it and I didn't want the overhead of calling it in some utility class. It's a bit too long and used in every single derived bullet class, making it probably not a good idea to inline. How would you suggest I define this function? As a static member function of Bullet, of a non-static member function of Bullet, or maybe not as a member of Bullet but defined outside of the class in Bullet.h? What are the advantages and disadvantages of each?

  • Non laggy movement in Flex or WPF

    I'm trying to learn something about 2D games programming. For this purpose I've downloaded many samples developed in: Flex and Microsoft WPF. I've noticed that all the animations / moving objects are kind of non-smooth. I've seen a Flex example with double buffering which solved the image flickering, but it was laggy too. WPF example too. Just to mentioned, all examples were drawing on Canvas. I'm just curious, is it possible to have a wonderful non-laggy movement on the GUI in Flash or WPF ? (e.g. like a real game, coded in C++)

  • querying huge database table takes too much of time in mysql

    - by Vijay
    Hi all, I am running sql queries on a mysql db table that has 110Mn+ unique records for whole day. Problem: Whenever I run any query with "where" clause it takes at least 30-40 mins. Since I want to generate most of data on the next day, I need access to whole db table. Could you please guide me to optimize / restructure the deployment model?
