• Spring's JdbcDaoSupport (using MySQL Connector/J) fails after executing sql that adds FK

  - by John

  I am using Spring's JdbcDaoSupport class with a DriverManagerDataSource using the MySQL Connector/J 5.0 driver (driverClassName=com.mysql.jdbc.driver). allowMultiQueries is set to true in the url. My application is an in-house tool we recently developed that executes sql scripts in a directory one-by-one (allows us to re-create our schema and reference table data for a given date, etc, but I digress). The sql scripts sometime contain multiple statements (hence allowMultiQueries), so one script can create a table, add indexes for that table, etc. The problem happens when including a statement to add a foreign key constraint in one of these files. If I have a file that looks like... --(column/constraint names are examples) CREATE TABLE myTable ( fk1 BIGINT(19) NOT NULL, fk2 BIGINT(19) NOT NULL, PRIMARY KEY (fk1, fk2) ); ALTER TABLE myTable ADD CONSTRAINT myTable_fk1 FOREIGN KEY (fk1) REFERENCES myOtherTable (id) ; ALTER TABLE myTable ADD CONSTRAINT myTable_fk2 FOREIGN KEY (fk2) REFERENCES myOtherOtherTable (id) ; then JdbcTemplate.execute throws an UncategorizedSqlException with the following error message and stack trace: Exception in thread "main" org.springframework.jdbc.UncategorizedSQLException: StatementCallback; uncategorized SQLException for SQL [ THE SQL YOU SEE ABOVE LISTED HERE ]; SQL state [HY000]; error code [1005]; Can't create table 'myDatabase.myTable' (errno: 150); nested exception is java.sql.SQLException: Can't create table 'myDatabase.myTable' (errno: 150) at org.springframework.jdbc.support.AbstractFallbackSQLExceptionTranslator.translate(AbstractFallbackSQLExceptionTranslator.java:83) at org.springframework.jdbc.support.AbstractFallbackSQLExceptionTranslator.translate(AbstractFallbackSQLExceptionTranslator.java:80) at org.springframework.jdbc.support.AbstractFallbackSQLExceptionTranslator.translate(AbstractFallbackSQLExceptionTranslator.java:80) and the table and foreign keys are not inserted. Also, especially weird: if I take the foreign key statements out of the script I showed above and then place them in their own script that executes after (so I now have 1 script with just the create table statement, and 1 script with the add foreign key statements that executes after that) then what happens is: tool executes create table script, works fine, table is created tool executes add fk script, throws the same exception as seen above (except errno=121 this time), but the FKs actually get added (!!!) In other words, when the create table/FK statements are in the same script then the exception is thrown and nothing is created, but when they are different scripts a nearly identical exception is thrown but both things get created. Any help on this would be greatly appreciated. Please let me know if you'd like me to clarify anything more.

• Making OR/M loosely coupled and abstracted away from other layers.

  - by Genuine

  Hi all. In an n-tier architecture, the best place to put an object-relational mapping (OR/M) code is in the data access layer. For example, database queries and updates can be delegated to a tool like NHibernate. Yet, I'd like to keep all references to NHibernate within the data access layer and abstract dependencies away from the layers below or above it. That way, I can swap or plug in another OR/M tool (e.g. Entity Framework) or some approach (e.g. plain vanilla stored procedure calls, mock objects) without causing compile-time errors or a major overhaul of the entire application. Testability is an added bonus. Could someone please suggest a wrapper (i.e. an interface or base class) or approach that would keep OR/M loosely coupled and contained in 1 layer? Or point me to resources that would help? Thanks.

• named type not used for constructor injection

  - by nmarun

  Hi, I have a simple console application where I have the following setup: public interface ILogger { void Log(string message); } class NullLogger : ILogger { private readonly string version; public NullLogger() { version = "1.0"; } public NullLogger(string v) { version = v; } public void Log(string message) { Console.WriteLine("NULL " + version + " : " + message); } } The configuration details are below: <type type="UnityConsole.ILogger, UnityConsole" mapTo="UnityConsole.NullLogger, UnityConsole"> My calling code looks as below: IUnityContainer container = new UnityContainer(); UnityConfigurationSection section = (UnityConfigurationSection)ConfigurationManager.GetSection("unity"); section.Containers.Default.Configure(container); ILogger nullLogger = container.Resolve(); nullLogger.Log("hello"); This works fine, but once I give a name to this type something like: <type type="UnityConsole.ILogger, UnityConsole" mapTo="UnityConsole.NullLogger, UnityConsole" name="NullLogger"> The above calling code does not work even if I explicitly register the type using container.RegisterType<ILogger, NullLogger>(); I get the error: {"Resolution of the dependency failed, type = \"UnityConsole.ILogger\", name = \"\". Exception message is: The current build operation (build key Build Key[UnityConsole.NullLogger, null]) failed: The parameter v could not be resolved when attempting to call constructor UnityConsole.NullLogger(System.String v). (Strategy type BuildPlanStrategy, index 3)"} Why doesn't unity look into named instances? To get it to work, I'll have to do: ILogger nullLogger = container.Resolve("NullLogger"); Where is this behavior documented? Arun

• Rails Model inheritance in forms

  - by Tiago

  I'm doing a reporting system for my app. I created a model ReportKind for example, but as I can report a lot of stuff, I wanted to make different groups of report kinds. Since they share a lot of behavior, I'm trying to use inheritance. So I have the main model: model ReportKind << ActiveRecord::Base end and created for example: model UserReportKind << ReportKind end In my table report_kinds I've the type column, and until here its all working. My problem is in the forms/controllers. When I do a ReportKind.new, my form is build with the '*report_kind*' prefix. If a get a UserReportKind, even through a ReportKind.find, the form will build the 'user_report_kind' prefix. This mess everything in the controllers, since sometimes I'll have params[:report_kind], sometimes params[:user_report_kind], and so on for every other inheritance I made. Is there anyway to force it to aways use the 'report_kind' prefix? Also I had to force the attribute 'type' in the controller, because it didn't get the value direct from the form, is there a pretty way to do this? Routing was another problem, since it was trying to build routes based in the inherited models names. I overcome that by adding the other models in routes pointing to the same controller.

• How to pass event to method?

  - by tomaszs

  I would like to create a method that takes as a argument an event an adds eventHandler to it to handle it properly. Like this: I have 2 events: public event EventHandler Click; public event EventHandler Click2; Now i would like to pass particular event to my method like this (pseudocode): public AttachToHandleEvent(EventHandler MyEvent) { MyEvent += Item_Click; } private void Item_Click(object sender, EventArgs e) { MessageBox.Show("lalala"); } ToolStripMenuItem tool = new ToolStripMenuItem(); AttachToHandleEvent(tool.Click); Is it possible or do I not understand it good? Edit: I've noticed with help of you that this code worked fine, and returned to my project and noticed that when I pass event declared in my class it works, but when I pass event from other class id still does not work. Updated above example to reflect this issue. What I get is this error: The event 'System.Windows.Forms.ToolStripItem.Click' can only appear on the left hand side of += or -=

• Products combining framework and visual IDE for web development?

  - by Tom Hubbard

  We are looking for some tools to help us with our web development speed. The two main areas that we have pinpointed as parts of the problem are "Framework/Flow Management" and "Visual/Layout Development" Ideally we would find a tool that handles both rather well. However, it seems like there are few tools that handle the middle ground well. Usually it is just a Framework, or and IDE, not both. The best thing we have found so far is Agile Platform. Are we missing any obvious products? Platform at this point is not a huge concern. We can migrate to the best tool.

• NAnt and relative path execution

  - by stacker

  How can I assign to trunk.dir property a relative path to the trunk location? This is my nant.build file: <?xml version="1.0" encoding="utf-8"?> <project name="ProjectName" default="build" xmlns="http://nant.sf.net/release/0.85/nant.xsd"> <!-- Directories --> <property name="trunk.dir" value="C:\Projects\ProjectName" /><!-- I want relative path over here! --> <property name="source.dir" value="${trunk.dir}src\" /> <!-- Working Files --> <property name="msbuild.exe" value="C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\msbuild.exe" /> <property name="solution.sln" value="${source.dir}ProjectName.sln" /> <!-- Called Externally --> <target name="compile"> <!-- Rebuild foces msbuild to clean and build --> <exec program="${msbuild.exe}" commandline="${solution.sln} /t:Rebuild /v:q" /> </target> </project>

• Use of putty in command line

  - by kij

  Hi, I'm trying to use putty in command line from an hudson job. The command is the following one: putty -ssh -2 -P 22 USERNAME@SERVER_ADDR -pw PASS -m command.txt Where 'command.txt' is a shell script to execute in the server through SSH. If i launch this command from the Window command prompt, it works, the shell script is executed on the server machine. If i launch a build of the hudson job configured with this batch command, it doesn't work. The build is running... and running... and running.. without doing anything, and i have to stop it manually. So my question is: Is it possible to launch an external programm (i.e. putty) from an hudson job ? ps: i tried SSH plugin but... not a really good plugin (pre/post build, fail status of the commands launched not caught by hudson, etc.) Thanks in advance for your help. Best regards. kij

• Can I have code that executes before and after tests are run by NUnit?

  - by Billy ONeal

  I've got a bunch of tests in NUnit which create garbage data on the filesystem (bad, I know, but I have little control over this). Currently we have a cleanup tool that removes these temporaries and such, but I'd like to be able to run that cleanup tool automatically. I'd have to be able to run it after all tests have finished running. I have similar checking that I'd like to do at the beginning, to ensure that there are none of these temporaries left from previous runs that might change the outcome of the tests. Is such a thing simple or am I going to have to implement a whole new test runner for such a thing?

• How to generate msdn documentation from javascript? preferably using sandcastle

  - by melaos

  hi is there a tool that i can use to generated msdn type documentation? i recently just started playing with sandcastle and i found that there used to a tool called scriptdoc but it has been absorbed into aptana and i don't really want to use aptana studio. what i could find so far is jsdoc which is a perl script which extracts comments from javascript files but i'm still looking for a better fit. from my initial testing it seems that the xml generated from jsdoc doesn't match completed with sandcastle or maybe i'm missing something there... any help?

• What's the difference between DI and factory patterns?

  - by Anthony Short

  I have a class which depends on 3 classes, all 3 of which have other classes they rely on. Currently, I'm using a container class to build up all the required classes, inject them into one another and return the application. The simplified version of the container looks something like this: class Builder { private $_options; public function __construct($options) { $this->_options = $options; } public function build() { $cache = $this->getCache(); $response = $this->getResponse(); $engine = $this->getEngine(); return new Application($cache,$response,$engine); } public function getResponse() { $encoder = $this->getResponseEncoder(); $cache = $this->getResponseCache(); return new Response($encoder,$cache); } // Methods for building each object } I'm not sure if this would be classified as FactoryMethod or a DI Container. They both seem to solve the same problem in the same way - They build objects and inject dependencies. This container has some more complicated building methods, like loading observers and attaching them to observable objects. Should factories be doing all the building (loading extensions etc) and the DI container should use these factories to inject dependencies? That way the sub-packages, like Cache, Response etc, can each have their own specialised factories.

• How can I copy an XmlNode from one XmlDocument to another?

  - by Chris Wenham

  I'm building a tool that authors/edits XML files, and I want to be able to populate it with template fragments defined in another XML file. For example, the tool has an "Add FooBarBaz Element" button that adds a element to the new document being created, and I want to add FooBarBaz by copying it from a template. Or let's say this is my template file: <Templates> <FooBarBaz Attribute="Value"> <ChildElement/> </FooBarBaz> </Templates> I can then grab a template fragment with .GetElementsByTagName("FooBarBaz"), and I'd like to be able to inject it into the new document with something like .AppendChild(templateNode). But the problem is that an XmlNode cannot be copied from one XmlDocument to another, even if you use .Clone() or .CloneNode(), because AppendChild() throws an exception saying that the template element belongs to another context. Is there an easy way to copy a System.Xml.XmlNode between System.Xml.XmlDocuments?

• Concerns with SoapUI Pro when Updating Web Services

  - by Plenoge

  This may unfortunately be a very open-ended question, but a coworker of mine has shared concerns about using SoapUI Pro as our automated regression testing tool primarily on the basis that seemingly trivial WSDL changes can cause headaches for the QA crew. My coworker's particularly concerned that if we update the WSDL, even with a name change, we'll need to touch and update each existing test. As I understand it SoapUI Pro offers a refactoring tool to handle this for you. What are your experiences with SoapUI Pro and updating your web services? Am I missing something?

• What are real-world examples of Gradle's dependency graph?

  - by Michael Easter

  As noted in the documentation, Gradle uses a directed acyclic graph (DAG) to build a dependency graph. From my understanding, having separate cycles for evaluation and execution is a major feature for a build tool. e.g. The Gradle doc states that this enables some features that would otherwise be impossible. I'm interested in real-world examples that illustrate the power of this feature. What are some use-cases for which a dependency graph is important? I'm especially interested in personal stories from the field, whether with Gradle or a similarly equipped tool. I am making this 'community wiki' from the outset, as it will be difficult to assess a 'correct' answer.

• How can I kill a Perl system call after a timeout?

  - by Fergal

  I've got a Perl script I'm using for running a file processing tool which is started using backticks. The problem is that occasionally the tool hangs and It needs to be killed in order for the rest of the files to be processed. Whats the best way best way to apply a timeout after which the parent script will kill the hung process? At the moment I'm using: foreach $file (@FILES) { $runResult = `mytool $file >> $file.log`; } But when mytool hangs after n seconds I'd like to be able to kill it and continue to the next file.

• How to read msmq messages (me, not the pc)

• Extracting public key from private key in OpenSSL

  - by ereOn

  Hello, I need to extract the RSA public key from a RSA private key using OpenSSL. I'm currently using RSAPublicKey_dup() passing the RSA* private key to get the public key. However, while the call seems to work, I cannot load (or use) this public key using the openssl command-line tool. If I generate the public key using the command-line tool ("$ openssl rsa -in private.pem -pubout > public.pem"), I can use it and it works like a charm. Do you guys know how I can get this work ? Maybe another function ? The OpenSSL documentation is quite hard to browse... Thank you.

• Can't unwrap Optional.None tableviewcell

  - by Mathew Padley

  I've a table view that has a custom table view cell in it. My problem is that when i try and assign a value to a variable in the custom table view cell I get the stated error. Now, I think its because the said variable is not initialised, but its got me completely stumped. This is the custom table cell: import Foundation import UIKit class LocationGeographyTableViewCell: UITableViewCell { //@IBOutlet var Map : MKMapView; @IBOutlet var AddressLine1 : UILabel; @IBOutlet var AddressLine2 : UILabel; @IBOutlet var County : UILabel; @IBOutlet var Postcode : UILabel; @IBOutlet var Telephone : UILabel; var location = VisitedLocation(); func Build(location:VisitedLocation) -> Void { self.location = location; AddressLine1.text = "test"; } } My cell for row at index path is: override func tableView(tableView: UITableView!, cellForRowAtIndexPath indexPath: NSIndexPath!) -> UITableViewCell! { var addressCell = tableView.dequeueReusableCellWithIdentifier("ContactDetail") as? LocationGeographyTableViewCell; if !addressCell { addressCell = LocationGeographyTableViewCell(style: UITableViewCellStyle.Value1, reuseIdentifier: "ContactDetail"); } addressCell!.Build(Location); return addressCell; } As I say I'm completely baffled, the Build function calls the correct function in the tableviewcell. Any help will be gratefully appreciated. Ta

• How can I determine which dependency would cause a C++ compilation unit to be rebuilt?

  - by Seb Rose

  I have a legacy C++ application with a deep graph of #includes. Changes to any header file often cause recompiles of seemingly unrelated source files. The application is built using a Visual Studio 2005 solution (sln) file. Can MSBUILD be invoked in a way that it reports which dependency(ies) are causing a source file to be recompiled? Is there any other tool that might be able to help? NOTE: I'm only looking for a tool to tell me why a file would be rebuilt, not some restrospective magic telling me why it was rebuilt.

• How do I deploy a utility with ocx dependency to a test machine without registering the ocx?

  - by Brandon

  I have a test utility that depends upon an ocx file that is installed/registered on my development machine. We'd like to run this tool on a test machine without polluting the machine with any unnecessary files. Nothing should be installed except the target machine software. Running the tool on a network drive or from a stand-alone directory copied to the test machine would be ideal. But, registering the ocx on the test machine is out of the question. Placing the ocx file in the same directory as the exe doesn't work. No matter what it still gives me this error--"The application has failed to start because the application configuration is incorrect. Reinstalling the application may fix the problem." What else can I try?

• setup Qt and PyQt on mac osx so my app can also deployable on windows

  - by hk_programmer

  Hi, I've been coding with Python and C++ and now need to work on building a gui for data visualization purposes. I work on Mac Snow Leopard (intel), python 3.1 using gcc 4.2.1 (from Xcode 3.1) I wanted to first install Qt and then PyQt. And my goals are to be able to: - quickly prototype GUI and the accompanied logic that drives the GUI using PyQt and python - if I decided I need the speed, or if it's fairly easy to translate my GUI into C++ using the Qt tools, I have the options to translate my app into C++ - Be able to deploy my application onto Windows (both the python and c++ version of my app) Give the goals above, what are the correct steps I should take and what issues i should be aware of when setting up Qt and PyQt. Which other deployment tools do I need? From my readings so far, here's what I have: download the Qt source for mac and configure it with -platform macx-g++42 -arch x86_64 -no-framework (i've read somewhere that building as framework causes some trouble in deployment and/or debugging, can't find the article anymore) download latest SIP source and build download latest PyQt and build from source (any special options I should pay attention to?) For deployment, I've read that I would need to use py2exe/cx_freeze for windows, p2app for mac: http://arstechnica.com/open-source/guides/2009/03/how-to-deploying-pyqt-applications-on-windows-and-mac-os-x.ars but seems like what the article describe is deploying an app you build on windows on the windows platform and vice versa. How do you deploy to windows (is it even possible?) if you are writing your Qt app on a mac ? Really appreciate the help

• Console-App to get all open files for processes

  Hi I am searching for a console-app (where I can pipe the output to a txt-file) which gives me a list of all current processes and the files which each process has open. The tool should also work when the user doesn't has administrativ-privilegues and it should also give file-path which are located on the network (UNC and absolute/mappings). Is there something like this which I can call from another tool and get the information? I am on a windows system. I have a open filename and need now to get the whole path for the file

• How to check if new version of Chrome is available?

  - by serg

  I am trying to build an extension that would notify a user when new version of Chrome is available. I tried to inspect network traffic when Chrome is checking for an update and it is sending a request to http://74.125.95.113/service/update2?w=3:{long_encoded_string} page that returns XML with information I need: <?xml version="1.0" encoding="UTF-8"?> <gupdate xmlns="http://www.google.com/update2/response" protocol="2.0" server="prod"> <daystart elapsed_seconds="31272"/> <app appid="{8A69D345-D564-463C-AFF1-A69D9E530F96}" status="ok"> <updatecheck status="noupdate"/> <ping status="ok"/> </app> </gupdate> Besides sending {long_encoded_string} as URL parameter it is also sending some encoded cookie. Maybe someone familiar with Chrome build process can shed some light on those encoded strings and how to build them? Maybe there is another easier way (I have a feeling that string encoding is a dead end for me)?
