What AOP tools exist for doing aspect-oriented programming at the assembly language level against x8

- by JohnnySoftware

Looking for a tool I can use to do aspect-oriented programming at the assembly language level. For experimentation purposes, I would like the code weaver to operate native application level executable and dynamic link libraries. I have already done object-oriented AOP. I know assembly language for x86 and so forth. I would like to be able to do logging and other sorts of things using the familiar before/after/around constructs. I would like to be able to specify certain instructions or sequences/patterns of consecutive instructions as what to do a pointcut on since assembly/machine language is not exactly the most semantically rich computer language on the planet. If debugger and linker symbols are available, naturally, I would like to be able to use them to identify subroutines' entry points , branch/call/jump target addresses, symbolic data addresses, etc. I would like the ability to send notifications out to other diagnostic tools. Thus, support for sending data through connection-oriented sockets and datagrams is highly desirable. So is normal logging to files, UI, etc. This can be done using the action part of an aspect to make a function call, but then there are portability issues so the tool needs to support a flexible, well-abstracted logging/notifying mechanism with a clean, simple yet flexible. The goal is rapid-QA. The idea is to be able to share aspect source code braodly within communties as well as publicly. So, there needs to be a declarative security policy file that users can share. This insures that nothing untoward that is hidden directly or indirectly in an aspect source file slips by the execution manager. The policy file format needs to be simple to read, write, modify, understand, type-in, edit, and generate. Sort of like Java .policy files. Think the exact opposite of anything resembling XML Schema files and you get the idea. Is there such a tool in existence already?

In which order is model binding and validation done in ASP.NET MVC 2?

- by Simon Bartlett

I am using ASP.NET MVC 2, and am using a view-model per view approach. I am also using Automapper to map properties from my domain-model to the view-model. Take this example view-model (with Required data annotation attributes for validation purposes): public class BlogPost_ViewModel { public int Id { get; set; } [Required] public string Title { get; set; } [Required] public string Text { get; set; } } In the post editor view I am using a rich text editor (CKeditor). Because CKeditor is a HTML editor, I ideally need CKeditor to HTMLencode the user's input when the form is submitted, so that ASP.NET's input validation does not complain. This is not a problem as CKeditor has this functionality built in, however I need CKeditor's output decoded before mapping back to the domain object (via Automapper). I am wanting to add a new property (to the view-model above) to solve this, as follows: public string HTMLEncodedText { get { return HTMLEncode(Text); } set { Text = HTMLDecode(value); } } I can then bind this property to CKeditor in the view, but still use Automapper to map the 'Text' property in the controller - all without having to turn input-validation off. My question is: do you know how the model binding and validation process in ASP.NET MVC 2 works? Are all model properties binded before validation is carried out? Or is each individual property get validated when it is being set. I think ideally for my idea to work, all properties need to be set before the model is validated.

Difficulties using custom control - RichTextEditor

- by Chris

I am working on a school project that uses ASP.NET. I found this TextEditor control ( http://blogs.msdn.com/kirti/archive/2007/11/10/rich-text-editor-is-here.aspx ) that I am trying to include but it isn't working. The error I am getting is: Error Rendering Control - TextEditor. An unhandled exception has occurred. Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index. I see this error when I go Design part of the editor. I just don't understand this error at all. Also I am a lil bit confused as there is no parameter called index. :( What I have done is reference the binary in my project and then on the page I am trying to use it have registered its namespace and assembly with this line: <%@ Register Assembly="RichTextEditor" Namespace="AjaxControls" TagPrefix="rtt" %> I then go ahead and try to add the control to the page with this line of code: <rtt:richtexteditor ID="TextEditor" Theme="Blue" runat="server" /> Any help would be much appreciated. I haven't done anything like add a custom control before.

Producing Mini Dumps for _caught_ SEH exceptions in mixed code DLL

- by Assaf Lavie

I'm trying to use code similar to clrdump to create mini dumps in my managed process. This managed process invokes C++/CLI code which invokes some native C++ static lib code, wherein SEH exceptions may be thrown (e.g. the occasional access violation). C# WinForms -> C++/CLI DLL -> Static C++ Lib -> ACCESS VIOLATION Our policy is to produce mini dumps for all SEH exceptions (caught & uncaught) and then translate them to C++ exceptions to be handled by application code. This works for purely native processes just fine; but when the application is a C# application - not so much. The only way I see to produce dumps from SEH exceptions in a C# process is to not catch them - and then, as unhandled exceptions, use the Application.ThreadException handler to create a mini dump. The alternative is to let the CLR translate the SEH exception into a .Net exception and catch it (e.g. System.AccessViolationException) - but that would mean no dump is created, and information is lost (stack trace information in Exception isn't as rich as the mini dump). So how can I handle SEH exceptions by both creating a minidump and translating the exception into a .Net exception so that my application may try to recover?

HP QTP 10: Web-app testing - SomeObj.FireEvent("OnCLick") works, SomeObj.Object.FireEvent("OnCLick") doesn't

- by Vitaliy

Hi all! I have rich web app btuil with ExtJS. It has multi-select list control (created with JS+CSS). I want to click on some item in that list using HP QuickTest Pro 10 with Internet Explorer 6. I added that item into Object repository and found that following code works - selects some item: Browser("blah").Page("blah").WebElement("SomeElem").Click next code also works: Browser("blah").Page("blah").WebElement("SomeElem").FireEvent("onMouseDown") Browser("blah").Page("blah").WebElement("SomeElem").FireEvent("onMouseUp") Browser("blah").Page("blah").WebElement("SomeElem").FireEvent("onClick") But I want to select several items using shift+click method. I don't know to do that :( So I have a few questions: How can perform click with mouse on several web elements with Shift key pressed? I tried to do that using CreateEventObject + shiftKey set to true, but the method (perform fireEvent on DOM object, not object from Object repository) doesn't work: Browser("blah").Page("blah").WebElement("SomeElem").Object.FireEvent("onClick") What the difference between WebElement("Element").FireEvent("OnClick") and WebElement("Element").Object.FireEvent("OnClick") ? Plsease, help someone, because I fought with that problem a lot, but had no result. Thanks!

WPF Spellcheck Engine takes up too much memory.

- by Matt H.

Each datatemplate in my WPF ItemsControl contains FIVE custom bindable richtextbox controls. It is a data-driven app that for authoring multiple-choice questions -- The question and four answer choices must all support: 1) Spell check 2) Rich formatting (otherwise I'd use regular textboxes) The spell check object in .NET 4 has a Friend constructor that takes a single argument of owner As TextBoxBase This means every richtextbox in the ItemsControl has 5 Spellcheck objects! This is the problem -- every spell check engine is consuming about 500k memory. So after you favor in the spellcheck, bindings, additional controls in the DataTemplate, etc.. a single multi choice question consumes more than 3MB memory. Users with 100--200 questions will quickly see the App raise it's memory consumption to 500+ MB. Management is definitely not OK with this. Is there a way to minimimze this problem? The best suggestion I've heard is to enable/disable spellcheck if the richtextbox is in the ItemsControl's scrollviewer: I haven't gotten an answer to how to go about it: (http://stackoverflow.com/questions/2869012/possible-to-implement-an-isviewportvisible-dependencyproperty-for-an-item-in-an-i) Any good ideas?

Wordpress.. Is it a CMS?

- by madcolor

I recently was contacted by a client who simply wanted to increase their organic rankings in Google. My approach was to do the following: A) Take them off of their overpriced host and move them to a nicer, cheaper, more feature-rich hosting solution which included a simple Wordpress install. B) Apply a theme to WordPress which followed the look and feel of their existing website. C) Train my client on how to login to their copy of Wordpress and create/manage pages/posts. This took me very little time.. Most of the work in converting asp forms into php and tweaking a theme to fit their design. Now my client is able to create/manage as many pages or posts as they desire. I believe, for this purpose, Worpress was the easiest solution. Would you categorize Wordpress as a CMS? Similar: http://stackoverflow.com/questions/250880/is-there-any-cms-better-than-wordpress-or-should-i-roll-my-own http://stackoverflow.com/questions/1101818/wordpress-as-a-cms-option http://stackoverflow.com/questions/490899/which-cms-to-choose http://stackoverflow.com/questions/629203/is-it-advisable-to-use-wordpress-as-cms-closed http://stackoverflow.com/questions/1451326/is-wordpress-good-for-building-a-large-cms-site-with-many-pages-about-over-100-00 External: http://codex.wordpress.org/User%3ALastnode/Wordpress%5FCMS http://wordpress.org/development/2009/11/wordpress-wins-cms-award/

Obj-C: ++variable is increasing by two instead of one

- by Eli Garfinkel

I am writing a program that asks users yes/no questions to help them decide how to vote in an election. I have a variable representing the question number called questionnumber. Each time I go through the switch-break loop, I add 1 to the questionnumber variable so that the next question will be displayed. This works fine for the first two questions. But then it skips the third question and moves on to the fourth. When I have more questions in the list, it skips every other question. Somewhere, for some reasons, the questionnumber variable is increasing when I don't want it to. Please look at the code below and tell me what I'm doing wrong. Thank you! Eli import "MainView.h" import @implementation MainView @synthesize Question; @synthesize mispar; int conservative = 0; int liberal = 0; int questionnumber = 1; (IBAction)agreebutton:(id)sender { ++liberal; } (IBAction)disagreebutton:(id)sender { ++conservative; } (IBAction)nextbutton:(id)sender { ++questionnumber; switch (questionnumber) { case 2: Question.text = @"Congress should pass a law that would ban Americans from earning more than one hundred million dollars in any given year."; break; case 3: Question.text = @"It is not fair to admit people to a university or employ them on the basis of merit alone. Factors such as race, gender, class, and sexual orientation must also be considered."; break; case 4: Question.text = @"There are two Americas - one for the rich and one for the poor."; break; case 5: Question.text = @"Top quality health care should be free for all."; break; default: break; } } @end

Prototype VS jQuery

- by aSeptik

Hi All guys! First of, thank's for your time; then i want go directly to the point by saying that, i don't want to open another "Yet Another Js VS Js" 3d , the web is almost busy of this! I want also make a premise, i have used both theese js frameworks and i love it and i know, that there are a lot of good js frameworks around, maybe better then this two; but, as you know we need to be perfomant and quickly by doing our works, so i want keep this two, that are the most famous and therefore have a great community support! now, if you are going to say me, that the choise depends on what i'm going to do!? then i can think, hey, in the end they are both javascript and they have almost the same methods and functions and for achieve a task they needs almost the same lines of code! So i want hear from you guys, from you that have really used one of theese, for a real Rich Internet Application what are the real points of force and what the weaknesses you find!? Regards.

Disable Painting of the VScrollbar in a System.Windows.Forms.RichTextBox

- by SchlaWiener

I have a custom control inherited from RichTextBox. This control has the ability to "disable" rich text editing. I achive this by just setting the Rtf property to the text property during the TextChanged event. this is how my code looks like: private bool lockTextChanged; void RichTextBox_TextChanged(object sender, EventArgs e) { // prevent StackOverflowException if (lockTextChanged) return; // remember current position int rtbstart = rtb.SelectionStart; int len = rtb.SelectionLength; // prevent painting rtb.SuspendLayout(); // set the text property to remove the entire formatting. lockTextChanged = true; rtb.Text = rtb.Text; rtb.Select(rtbstart, len); lockTextChanged = false; rtb.ResumeLayout(true); } That worked well. However in a large text with like 200 lines the controls jitters (you see the first lines of text for the wink). To prevent that from happening I filter the WM_PAINT between SuspendLayout() and ResumeLayout() private bool layoutSuspended; public new void SuspendLayout() { layoutSuspended = true; base.SuspendLayout(); } public new void ResumeLayout() { layoutSuspended = false; base.ResumeLayout(); } public new void ResumeLayout(bool performLayout) { layoutSuspended = false; base.ResumeLayout(performLayout); } private const int WM_PAINT = 0x000F; protected override void WndProc(ref System.Windows.Forms.Message m) { if (!(m.Msg == WM_PAINT && layoutSuspended)) base.WndProc(ref m); } that did the trick, the RichTextBox isn't jittering anymoe. That's what I wanted to achive, except one thing: The scrollbar is still jittering everytime I type text to my control. Now my question: Does anyone have a clue for me how to prevent the scrollbar from redrawing during Suspend/Resume Layout?

Implementing subtables in JSF 1.1

- by Xenon

We're looking for a way to implement subtables in JSF 1.1. We cannot use Rich Faces due to the fact that out target server is WebSphere 6.1. I've tried JSTL and Tomahawk to no avail. Also, our project is using JSP's and not facelets. Here's my HTML/JSTL example: <table border="1" width="700px"> Header 1 Header 2 Header 3 Header 4 Header 5 ${item.value1} ${item.value2} ${item.value3} ${item.value4} ${item.value5} <tr> <td colspan="5"> <table border="1" width="100%"> <thead> <tr> <td>SubHeader 1</td> <td>SubHeader 2</td> <td>SubHeader 3</td> <td>SubHeader 4</td> <td>SubHeader 5</td> </tr> </thead>  <c:forEach var="subitem" items="${item.subtable}"> <tr> <td>${subitem.value1}</td> <td>${subitem.value2}</td> <td>${subitem.value2}</td> <td>${subitem.value2}</td> <td>${subitem.value2}</td> </tr> </c:forEach> </table> </td> </tr>

Should I use formal methods on my software project?

- by Michael

Our client wants us to build a web-based, rich internet application for gathering software requirements. Basically it's a web-based case tool that follows a specific process for getting requirements from stakeholders. I'm the project manager and we're still in the early phases of the project. I've been thinking about using formal methods to help clarify the requirements for the tool for both my client and the developers. By formal methods I mean some form of modeling, possibly something mathematically-based. Some of the things I've read about and are considering include Z (http://en.wikipedia.org/wiki/Z_notation), state machines, UML 2.0 (possibly with extensions such as OCL), Petri nets, and some coding-level stuff like contracts and pre and post conditions. Is there anything else I should consider? The developers are experienced but depending on the formalism used they may have to learn some math. I'm trying to determine whether it's worth while for me to use formal methods on this project and if so, to what extent. I know "it depends" so the most helpful answers for me is a yes/no and supporting arguments. Would you use formal methods if you were on this project?

PHP: Aggregate Model Classes or Uber Model Classes?

- by sunwukung

In many of the discussions regarding the M in MVC, (sidestepping ORM controversies for a moment), I commonly see Model classes described as object representations of table data (be that an Active Record, Table Gateway, Row Gateway or Domain Model/Mapper). Martin Fowler warns against the development of an anemic domain model, i.e. a class that is nothing more than a wrapper for CRUD functionality. I've been working on an MVC application for a couple of months now. The DBAL in the application I'm working on started out simple (on account of my understanding - oh the benefits of hindsight), and is organised so that Controllers invoke Business Logic classes, that in turn access the database via DAO/Transaction Scripts pertinent to the task at hand. There are a few "Entity" classes that aggregate these DAO objects to provide a convenient CRUD wrapper, but also embody some of the "behaviour" of that Domain concept (for example, a user - since it's easy to isolate). Taking a look at some of the code, and thinking along refactoring some of the code into a Rich Domain Model, it occurred to me that were I to try and wrap the CRUD routines and behaviour of say, a Company into a single "Model" class, that would be a sizeable class. So, my question is this: do Models represent domain objects, business logic, service layers, all of the above combined? How do you go about defining the responsibilities for these components?

ComDlg32.ocx Error: Object doesn't support this property or method

- by abhilashca

I'm developing an html editor using ComDlg32.ocx (Commom Dialog Control), using HTML and VBScript. My exact requirement was to prompt Open/Save/Color/Print/Font dialog boxes.Ive written code for prompting Save file dialog box. Also I've added a license file using LPK Tool onto my webpage. My html-source looks like: <body>  <object classid="clsid:5220cb21-c88d-11cf-b347-00aa00a28331"> <param name="LPKPath" value="License/comdlg.lpk" /> </object>  <object classid="CLSID:F9043C85-F6F2-101A-A3C9-08002B2F49FB" codebase="http://activex.microsoft.com/controls/vb6/COMDLG32.CAB" id="objComDlg"></object> </body> Now, here comes my error. Whenever I try to call the vbscript for prompting the Save File dialog box, Im getting an error as : Object doesn't support this property or method: 'objComDlg.Filter' If I comment out the objComDlg.Filter then the error move on to objComDlg.DialogTitle and thus it goes on. And my VBScript look like: FILE_FORMATS = "Rich Text Format (*.rtf)|*.rtf|Microsoft Word (*.doc)|*.doc|ANSI Text Document (*.txt)|*.txt" objComDlg.Filter = FILE_FORMATS <--- Error shows here objComDlg.DialogTitle = "Save As " objComDlg.Flags = cdlOFNFileMustExist Or cdlOFNHideReadOnly objComDlg.CancelError = True objComDlg.ShowSave Does anyone have an idea why this is happening? Is there any proper documentation for using this particular ActiveX control? My current development is in stand-still due to this error. Any help will be appreciated. Looking forward for your response. BTW, I'm using Windows XP SP3 and IE8 for my development. Thanks.

RichEdit VCL and URLs. Workarounds for OnPaint Issues.

- by HX_unbanned

So, issue is with the thing Delphi progies scare to death - Rich Edit in Windows ( XP and pre-XP versions ). Situation: I have added EM_AUTOURLDETECTION in OnCreate of form. Target - RichEdit1. Then, I have form, that is "collapsed" after showing form. RichEdit Control is sattic, visible and enabled, but it is "hidden" because form window is collapsed. I can expand and collapse form, using Button1 and changing forms Constraints and Size properties. After first time I expand form, the URL inside RichEdit1 control is highlighted. BUT - After second, third, fourth, etc... time I Collapse and Expand form, the RichEdit1 Control does not highlight URL anymore. I have tried EM_SETTEXTMODE messages, also WM_UPDATEUISTATE, also basic WM_TEXT message - no luck. It sems like this merssage really works ( enables detection ) while sending keyboard strokes ( virtual keycodes ), but not when text has been modified. Also - I am thinking to rewrite code to make RichEdit Control dynamic. Would this fix the problem? Maybe solution is to override OnPaint / OnDraw method to avoid highlight ( formatting ) losing when collapsing or expanding form? Weird is that my Embarcadero Documentation says this function must work in any moment text has been modified. Why it does not work? Any help appreciated. I am making this Community Wiki because this is common problem and togewther we cam find solution, right? :) Also - follow-ups and related Question: http://stackoverflow.com/questions/738694/override-onpaint http://stackoverflow.com/questions/478071/how-to-autodetect-urls-in-richedit-2-0 http://www.vbforums.com/archive/index.php/t-59959.html

Uncaught exception while using xdebug

- by rich97

I'm not too great with xdebug so forgive me if this is a stupid question. But I installed it on a separate machine and it performed some magic for me like formating my var_dump() output and catching any uncaught exceptions. It also fails to format the stack traces, outputting plain text which is extremely hard to read. As I am learning the Lithium PHP Framework I am required to use php5.3, on my other machine I compiled from the source but on this machine I'm using the precompiled packages from dotdeb.org. As far as I can tell the only difference is that this is a slightly newer version of php and it comes with the Suhosin patch. The other odd thing is that the xdebug functions such as xdebug_var_dump() work, aside from poor formatting. This is an Ubuntu machine, so I don't know if it could be anything to do with the dotdep packages, but I have installed xdebug through pecl, the downloadable tarball and from the SVN repository. But to no avail. You can see my php.ini and output of php -i in the following gist. I copied php.ini from /etc/php5/apache2/php.ini over to /etc/php5/cli/php.ini so php -i should reflect my apache setup. http://gist.github.com/391675 Any help is appreciated. Rich

Is there a language with native pass-by-reference/pass-by-name semantics, which could be used in mod

- by Bubba88

Hi! This is a reopened question. I look for a language and supporting platform for it, where the language could have pass-by-reference or pass-by-name semantics by default. I know the history a little, that there were Algol, Fortran and there still is C++ which could make it possible; but, basically, what I look for is something more modern and where the mentioned value pass methodology is preferred and by default (implicitly assumed). I ask this question, because, to my mind, some of the advantages of pass-by-ref/name seem kind of obvious. For example when it is used in a standalone agent, where copyiong of values is not necessary (to some extent) and performance wouldn't be downgraded much in that case. So, I could employ it in e.g. rich client app or some game-style or standalone service-kind application. The main advantage to me is the clear separation between identity of a symbol, and its current value. I mean when there is no reduntant copying, you know that you're working with the exact symbol/path you have queried/received. And intristing boxing of values will not interfere with the actual logic of program. I know that there is C# ref keyword, but it's something not so intristic, though acceptable. Equally, I realize that pass-by-reference semantics could be simulated in virtually any language (Java as an instant example) and so on.. not sure about pass by name :) What would you recommend - create a something like DSL for such needs wherever it be appropriate; or use some languages that I already know? Maybe, there is something that I'm missing? Thank you!

Trying to find a PHP5 API-based embeddable CMS

- by StrangeElement

I've been making the rounds for a CMS that I can use as an API, in a sort of "embedded" mode. I mean by this that I don't want the CMS to do any logic or presentation. I want it to be used as an API, which I can then use within an existing site. I don't want to be tied to the architecture of the CMS. A good example of this is NC-CMS (http://www.nconsulting.ca/nc-cms/). All it needs is an include at the top, then wherever editable content is desired it's only a function call with a unique label. It's also perfect in the sense that it allows to differentiate between small strings (like titles, labels) and texts (which require a rich-text editor). It's the only CMS I found that fits this description, but it is a little too light as it does not handle site structure. I need to be able to allow my client to add pages, choosing an existing template for the layout. A minimal back-end is required. Wordpress also fits some requirements in that it handles only content editing and allows freedom for the themes by letting them call the content where and how they want it. But it is article-based and backwards, in that it embeds sites (as themes) within its structure, rather than being embeddable in sites like NC. It's funny how checking out all the CMS out there, almost all of them claim that most CMS are not self-sufficient, that they do not handle application logic, while (almost) every single on I found with only one exception do so. Many are mostly article-based blog engines, which does not fit my need. I would appreciate any CMS that fits the general description.

Looking for pros/cons of using GWT or JSF

- by cliff.meyers

I'm a long time Java developer who has been building UI with Adobe Flex for the past few years. I'm looking to broaden my repertoire with a RIA technology that runs in a plain-old browser, no plug-ins required. I've read a lot about GWT but don't know much about JSF, especially given the varying implementations. Below are some criteria that are important to me as a developer. I'm hoping that the community might be able to tell me about the strengths and weaknesses of GWT and JSF in each: Layout: is it declarative, programmatic or a mix of both? Control library: how rich is the available control library? How easy is it to extend or write custom controls that "play nice" with the built-ins? Javascript: how much of it do I need to write in order to be successful with the framework? Cross-browser: assuming I'm not writing a lot of my own HTML and JS, do the frameworks function equally well in all modern browsers? Tooling: is a rapid edit/refresh cycle available? How easy is it to debug the client and server code? Bookmarking / Browser Navigation: this is a common problem in Flex; does the framework play nicely with these? I would love to hear any other important pros / cons I might not have covered. Thanks!

JSF - Creating an overlay for popup panels.

- by Ben

Hi, I've created an overlay that will popup whenever someone wants to upload a file to the system. The Gui looks like this (when the overlay is up) I have two problems with this: I attached a a4j:support object that, onclick, makes the overlay disappear. The problem with this is that when I click the upload button on the upload component, support catches the click event and closes the overlay with the upload component before I have the chance to finish the operation. I chose two different style classes. One for the overlay and one for the upload panel. But the styling of the overlay takes over the upload component and it becomes transparent as well. The implementation looks something like this: <h:panelgroup layout="block" styleClass="overlayClass"> <rich:fileUpload styleClass="uploadStyleClass"... /> <a4j:support event="onclick" action="#{mrBean.switchOverlayState}" reRender="..."/> </h:panelGroup> The CSS: .overlayClass { Opacity: 0.5; position: fixed; left: 0; right: 0; top: 0; bottom: 0; background: #000; } .uploadStyleClass { opacity: 1.0; ... } Thanks for the help!

Using Hibernate with MS ACCESS 2007 Database (Free JDBC Driver)

- by Quentin T.

1. I want to do a reverse engineering action with the Hibernate plugin of Eclipse on a MS Access 2007 Database. I'm forced to use a existing MS Access 2007 db. A easy solution is to buy the HXTT. But I want to use a free driver to do my work. So I tried to apply this post : http://www.programmingforfuture.com/2011/06/how-to-use-ms-access-with-hibernate.html (That uses the SQL Server dialect and the driver sun.jdbc.odbc.JdbcOdbcDriver) Unfortunately I have an error that nobody seems to have been on the internet: Exception while generating code Reason : org.hibernate.exception.GenericJDBCException: Error while reading primary key meta data for `c:/myaccessdb.mdb`.TableTest1 I have try to change the primary key on my MS Access DB (deleting all primary key) or to try the reverse engineering on a MS ACCESS with only one table without primary key, but I got all times the problems. 2. The purpose of my job is to transfer daily (weekly) an Oracle 11g database with data from an existing database MS ACCESS 2007. And I thought to use a procedure (Hibernate EJB) Java to be launched automatically every week to do the data transfer. Is this is the best solution ? Configuration : sun.jdbc.odbc.JdbcOdbcDriver v??? Hibernate v3.4 Eclipse ps: If you are a HXTT developer or seller please be indulgent with my post ;). Making money by making people believe that you help, it's bad ! A solution is to use Derby Client driver, as the solution in the post: Does anyone know if Hibernate and java will work effectively with Access? But a clarification of the answer of Rich Seller is required. Could you explain your answer and explain your configuration (hibernate.cfg.xml, persistence.xml and what URL you use in the property name="hibernate.connection.url") without using paying HXTT driver but with the free Derby driver.
