  • How do I map common properties in NHibernate

    - by Ian Oakes
    In the database I'm working with, every table repeats the same nine columns and I don't want to have to supply the same properties in each of my entities to map these columns. I've tried adding properties to a common base class and adding them to the sub class's mapping file, but this doesn't work. I've read the documentation around inheritance mapping but this did not help. What is the best way to map columns that repeat accross multiple tables in NHibernate?

  • Editing a .class file directly, playing around with opcodes

    - by echox
    Hi, today I just tried to play a little bit around with the opcodes in compiled java class file. After inserting iinc 1,1 the java virtual machine responds with: Exception in thread "main" java.lang.ClassFormatError: Truncated class file at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClassCond(ClassLoader.java:632) at java.lang.ClassLoader.defineClass(ClassLoader.java:616) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:141) at java.net.URLClassLoader.defineClass(URLClassLoader.java:283) at java.net.URLClassLoader.access$000(URLClassLoader.java:58) at java.net.URLClassLoader$1.run(URLClassLoader.java:197) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:190) at java.lang.ClassLoader.loadClass(ClassLoader.java:307) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:248) Could not find the main class: Test. Program will exit. This is my example source code: public class Test { public static void main(String[] args) { int i = 5; i++; i++; i++; System.out.println("Number: " + i + "\n"); } } The opcode for an increment is 0x84 + 2 bytes for operands. There's only one section in the resulting class file, which contains 0x84: [..] 8401 0184 0101 8401 01[..] So I would translate this as: iinc 1,1 iinc 1,1 iinc 1,1 corresponding to my i++; i++; i++; I then tried to append just 840101 to increment the variable once more, but that didn't work and resulted in the ClassFormatError. Is there anything like a checksum for the class file? I looked up the format of a classfile in http://java.sun.com/docs/books/jvms/second_edition/html/ClassFile.doc.html but could not find anything which points out to some kind of bytes_of_classfile or something. I also don't understand why the error is "Truncated Class File", because I did append something :-) I know its not a good idea to edit class files directly, but I'm just interested on the VM internals here.

  • do's and don'ts for writing mysql queries

    - by nik
    One thing I always wonder while writing query is that am I writing most optimized query or not? I know certain things like: 1) using SELECT field1, filed2 instead of SELECT * 2) Giving proper indexes to the tables but I am sure there are more things that should be kept in mind for writing queries, since most of the database can only grow more and optimal query will help gr8 in execution time, Can u share some tips and tricks on writing queries?

  • Javascript: "Dangling" Reference to DOM element?

    - by Channel72
    It seems that in Javascript, if you have a reference to some DOM element, and then modify the DOM by adding additional elements to document.body, your DOM reference becomes invalidated. Consider the following code: <html> <head> <script type = "text/javascript"> function work() { var foo = document.getElementById("foo"); alert(foo == document.getElementById("foo")); document.body.innerHTML += "<div>blah blah</div>"; alert(foo == document.getElementById("foo")); } </script> </head> <body> <div id = "foo" onclick='work()'>Foo</div> </body> </html> When you click on the DIV, this alerts "true", and then "false." So in other words, after modifying document.body, the reference to the DIV element is no longer valid. This behavior is the same on Firefox and MSIE. Some questions: Why does this occur? Is this behavior specified by the ECMAScript standard, or is this a browser-specific issue? Note: there's another question posted on stackoverflow that seems to be referring to the same issue, but neither the question nor the answers are very clear.

  • How to store a file on a server(web container) through a Java EE web application?

    - by Yatendra Goel
    I have developed a Java EE web application. This application allows a user to upload a file with the help of a browser. Once the user has uploaded his file, this application first stores the uploaded file on the server (on which it is running) and then processes it. At present, I am storing the file on the server as follows: try { FormFile formFile = programForm.getTheFile(); // formFile represents the uploaded file String path = getServlet().getServletContext().getRealPath("") + "/" + formFile.getFileName(); System.out.println(path); file = new File(path); outputStream = new FileOutputStream(file); outputStream.write(formFile.getFileData()); } where, the formFile represents the uploaded file. Now, the problem is that it is running fine on some servers but on some servers the getServlet().getServletContext().getRealPath("") is returning null so the final path that I am getting is null/filename and the file doesn't store on the server. When I checked the API for ServletContext.getRealPath() method, I found the following: public java.lang.String getRealPath(java.lang.String path) Returns a String containing the real path for a given virtual path. For example, the path "/index.html" returns the absolute file path on the server's filesystem would be served by a request for "http://host/contextPath/index.html", where contextPath is the context path of this ServletContext. The real path returned will be in a form appropriate to the computer and operating system on which the servlet container is running, including the proper path separators. This method returns null if the servlet container cannot translate the virtual path to a real path for any reason (such as when the content is being made available from a .war archive). So, Is there any other way by which I can store files on those servers also which is returning null for getServlet().getServletContext().getRealPath("")

  • PHP Unicode character questions

    - by user271619
    Here's a link I found, which even has a character I need to play with for other projects of mine. http://www.fileformat.info/info/unicode/char/2446/index.htm There is a box with the Title of: "Encodings" on that page. And I am wondering about some of the rows. I obviously need a course on this sort of thing, but I'm wondering what the difference is between "HTML Entity (decimal)" and "HTML Entity (hex)". The funny thing is, which confuses me, I throw those characters on a web page, and they display fine. But I haven't specified any UTF-8 encoding in the php page. <?php $string1 = '&#x2446;'; $string2 = '&#9286;'; echo $string1; echo '<br>'; echo $string2; ?> Does the browser know how to display both automatically? And to make it weirder, I can only see those characters on my Mac, in Firefox. But my windows box doesn't want to show them. I've tested it in chrome, and firefox. Do I need to tell the browsers to view them correctly? Or is it an operating system modification?

  • Rails does not display error messages on a form in a custom method

    - by slythic
    Hi all, I've created a custom method called checkout in my app. I create an order (which is done my adding products to my "cart"), assign it to my client, and then I head to my checkout screen where I confirm the items and enter their customer order number and complete the order (submit). Everything works great except that it doesn't display error messages. I'm able to display a flash error notice (seen in complete_order method) when things go wrong but it doesn't specify the details like a normal form would. The error messages should appear if the customer order number is not unique for that client. Below is the custom method (checkout) related code. Order Model: validates_uniqueness_of :customer_order_number, :scope => :client_id Orders_controller: def checkout @order = current_order end def complete_order @order = current_order respond_to do |format| if @order.update_attributes(params[:order]) @order.complete #sets submitted datetime and state to 'complete' flash[:notice] = 'Thank you! Your order is being processed.' format.html { redirect_to( products_path ) } format.xml { head :ok } else flash[:error] = 'Please review your items' #added to confirm an error is present format.html { redirect_to( checkout_path ) } format.xml { render :xml => @order.errors, :status => :unprocessable_entity } end end end And the form in the checkout view: <% form_for @order, :url => { :controller => "orders", :action => "complete_order" } do |f| %> <%= f.error_messages %> <%= f.text_field :customer_order_number, :label => "Purchase Order Number" %> <p> <%= f.submit 'Complete Order', :confirm => 'Are you sure?' %> <small> or <%= link_to 'cancel', current_cart_path %></small> </p> <% end %> Any idea how I can display the specific error messages? Thank you in advance! -Tony

  • document.onkeyup triggers when it shouldn't

    - by vonkow
    So I have the following code, which should append 'true' to the div "test" every 25ms as long as key 68 (the d key) is being pressed, right? <html> <body> <div id="test"></div> <script type="text/javascript"> var key=false; var keyDown=function(e) { if (e.keyCode==68) { key=true; } } var keyUp=function(e) { if (e.keyCode==68) { key=false; } } document.onkeydown=keyDown; document.onkeyup=keyUp; var run=function() { document.getElementById('test').appendChild(document.createTextNode(key+'\n')); t = setTimeout('run()', 25); } var t = setTimeout('run()', 25); </script> </body> </html> Save the code, load it in a browser and hold down on the d key. If I'm not crazy, you'll see that it occasionally appends 'false' even though the d key was never released. (I've tried this in FF and Chrome in Linux and Vista). Anybody happen to know why, or have a workaround?

  • Jquery - binding click event to a variable

    - by Kayote
    All, I am really stuck/ confused at this point. I have an array with 6 items in it. Each item in the array is dynamically filled with elements using jquery '.html' method. However, I cannot seem to be able to attach/ bind an event to this dynamically created variable. As soon as the browser gets to the problem line (see the area labeled 'PROBLEM AREA'), I get a 'undefined' error, which is really confusing as all the previous code on the very same variable works just fine. var eCreditSystem = document.getElementById("creditSystem"); var i = 0; var eCreditT = new Array(6); // 6 members created which will be recycled function createCreditTransaction () // func called when a transaction occurs, at the mo, attached to onclick() { if (i < 6) { eCreditT[i] = undefined; // to delete the existing data in the index of array addElements (i); } else if (i > 5 || eCreditT[i] != undefined) { ... } } function addElements (arrayIndex) // func called from within the 'createCreditTransaction()' func { eCreditT[i] = $(document.createElement('div')).addClass("cCreditTransaction").appendTo(eCreditSystem); $(eCreditT[i]).attr ('id', ('trans' + i)); $(eCreditT[i]).html ('<div class="cCreditContainer"><span class="cCreditsNo">-50</span>&nbsp;<img class="cCurrency" src="" alt="" /></div><span class="cCloseMsg">Click box to close.</span><div class="dots"></div><div class="dots"></div><div class="dots"></div>'); creditTransactionSlideOut (eCreditT[i], 666); // calling slideOut animation console.log(eCreditT[i]); // this confirms that the variable is not undefined /* ***** THE PROBLEM AREA ***** */ $(eCreditT[i]).on ('click', function () // if user clicks on the transaction box { creditTransactionSlideBackIn (eCreditT[i], 150); // slide back in animation }); return i++; }

  • JSF 2.0 Dynamic Views

    - by Robe Eleckers
    Hello, I'm working on a web project which uses JSF 2.0, PrimeFaces and PrettyFaces as main frameworks / libraries. The pages have the following (common) structure: Header, Content, Footer. Header: The Header always contains the same menu. This menu is a custom component, which generates a recursive html <ul><li> list containing <a href="url"> html links, this is all rendered with a custom renderer. The link looks like 'domain.com/website/datatable.xhtml?ref=2'. Where the ref=2 used to load the correct content from the database. I use prettyfaces to store this request value in a backingbean. Question 1: Is it ok to render the <a href> links myself, or should I better add an HTMLCommandLink from my UIComponent and render that in the encodeBegin/End? Question 2: I think passing variables like this is not really the JSF 2.0 style, how to do this in a better way? Content: The content contains dynamic data. It can be a (primefaces) datatable, build with dynamic data from the database. It can also be a text page, also loaded from the database. Or a series of graphs. You got the point, it's dynamic. The content is based on the link pressed in the header menu. If the content is of type datatable, then I put the ref=2 variable to a DataTableBean (via prettyfaces), which then loads the correct datatable from the database. If the content is of type chart, I'll put it on the ChartBean. Question 3: Is this a normal setup? Ideally I would like to update my content via Ajax. I hope it's clear :)

  • JPA Secondary Table Issue

    - by Smithers
    I have a three tables: User, Course, and Test. Course has a User foreign key and Test has a Course foreign key. I am having trouble mapping the Test collection for each User since I need an intermediary step from User - Course - Test. I am trying to use a SecondaryTable since the User key for the Test is its associated Course row. Am I on the right track using SecondaryTable or is there a way to use a JoinTable without the inverseJoinColumn?

  • bing search api ajax does not work

    - by jhon
    Hi guys, I want to use the Bing's search api with javascript. Actually, I want the user to write something and query Bing in order to get just images. so, I tried it using ajax. If I try the url http://api.search.live.net/xml.aspx?Appid=[YOURAPIKEY]&sources=image&query=home directly (with the browser) I do get an xml document. but if I use XMLHttpRequest it does not work. <html> <body> <script> var xhr = new XMLHttpRequest(); var url="http://api.search.live.net/xml.aspx?Appid=[YOURAPIKEY]&sources=image&query=home" xhr.open("GET", url, true ); xhr.onreadystatechange=function(){ /*if( xhr.readyState == 4 && xhr.status == 200) { document.write( xhr.responseText ); }*/ alert( xhr.readyState +" "+xhr.status +xhr.statusText +xhr); }; xhr.send(null); </script> </body> </html> Questions: 1) why does the code from above does not work? 2) any other way to do this without XMLHttpRequest? thanks. btw. I'm just interested in fix this for Firefox and without external libraries (jquery and so on).

  • 2 different routes on one page?

    - by Dejan.S
    Hi I'm pretty new with MVC2 or MVC in general. If it's one thing I get caught up with it's routes. Like now I got this scenario. Im going from the regular site to Admin. My navigation is the same partialview on both I just do a check which data to render something like this. <% if (!Request.RawUrl.Contains("Admin")){%> <% foreach (var site in Model) { %> <%= Html.MenuItem(site.BelongSite, "Sida", "Site", site.BelongSite) %> | <%} %> <%} else {%> <%= Html.ActionLink("Konfig", "Konfigurera", "Admin") %> <% } %> My route looks like this routes.MapRoute( "Admin", // Route name "Admin/{action}/{name}", // URL with parameters new { controller = "Admin", action = "konfigurera", name = UrlParameter.Optional } // Parameter defaults ); On my View called Konfigurera I got Edit sites and they use the route above and it works great. The navigation tho dont get no action assigned to it. It's just <a href='Admin/'> The navigation is in the shared folder, and it is a strongly typed. Any Ideas? I been struggling with this for about a hour now Thanks for any input

  • Database model for saving random boolean expressions

    - by zarko.susnjar
    I have expressions like this: (cat OR cats OR kitten OR kitty) AND (dog OR dogs) NOT (pigeon OR firefly) Anyone having idea how to make tables to save those? Before I got request for usage of brackets, I limited usage of operators to avoid ambiguous situations. So only ANDs and NOTs or only ORs and saved those in this manner: operators id | name 1 | AND 2 | OR 3 | NOT keywords id | keyword 1 | cat 2 | dog 3 | firefly expressions id | operator | keywordId 1 | 0 | 1 1 | 1 | 2 1 | 3 | 3 which was: cat AND dog NOT firefly But now, I'm really puzzled...

  • RavenDB Ids and ASP.NET MVC3 Routes

    - by goober
    Hey all, Just building a quick, simple site with MVC 3 RC2 and RavenDB to test some things out. I've been able to make a bunch of projects, but I'm curious as to how Html.ActionLink() handles a raven DB ID. My example: I have a Document called "reasons" (a reason for something, just text mostly), which has reason text and a list of links. I can add, remove, and do everything else fine via my repository. Below is the part of my razor view that lists each reason in a bulleted list, with an Edit link as the first text: @foreach(var Reason in ViewBag.ReasonsList) { <li>@Html.ActionLink("Edit", "Reasons", "Edit", new { id = Reason.Id }, null) @Reason.ReasonText</li> <ul> @foreach (var reasonlink in Reason.ReasonLinks) { <li><a href="@reasonlink.URL">@reasonlink.URL</a></li> } </ul> } The Problem This works fine, except for the edit link. While the values and code here appear to work directly (i.e the link is firing directly), RavenDB saves my document's ID as "reasons/1". So, when the URL happens and it passes the ID, the resulting route is "http://localhost:4976/Reasons/Edit/reasons/2". So, the ID is appended correctly, but MVC is interpreting it as its own route. Any suggestions on how I might be able to get around this? Do I need to create a special route to handle it or is there something else I can do?
