  • Does Hibernate create tables in the database automatically.

    - by theJava
    http://www.vaannila.com/spring/spring-hibernate-integration-1.html Upon reading this tutorial, they have not mentioned anything over creating tables in the DB. Does the Hibernate handle it automatically by creating tables and fields once i specify them. Here is my beans configuration. <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd"> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/WEB-INF/jsp/" p:suffix=".jsp" /> <bean id="myDataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> <property name="driverClassName" value="com.mysql.jdbc.Driver"/> <property name="url" value="jdbc:mysql://127.0.0.1:3306/spring"/> <property name="username" value="monwwty"/> <property name="password" value="www"/> </bean> <bean id="mySessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"> <property name="dataSource" ref="myDataSource" /> <property name="annotatedClasses"> <list> <value>uk.co.vinoth.spring.domain.User</value> </list> </property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop> <prop key="hibernate.show_sql">true</prop> <prop key="hibernate.hbm2ddl.auto">create</prop> </props> </property> </bean> <bean id="myUserDAO" class="uk.co.vinoth.spring.dao.UserDAOImpl"> <property name="sessionFactory" ref="mySessionFactory"/> </bean> <bean name="/user/*.htm" class="uk.co.vinoth.spring.web.UserController" > <property name="userDAO" ref="myUserDAO" /> </bean> </beans>

  • How do you set rate limit access to your API using Iptables?

    - by Cory
    How can you set rate limit access to API using Iptables. Tried to set limit using port 80, but I don't want to set limit to the web access entirely. Is there a way to specified a subdomain rather than port. Example: set rate limit to api.example.com not example.com? If there is no way to set rate limit by subdomain, what is the suggested rate limit access to port 80 without risking blocking a legitimate web user? One connection per second would be enough?

  • How Can I Automatically Execute A Link In Internet Explorer

    - by Martin
    I am trying to create an application to print documents over the web. I have created my document, and made a web page with a meta refresh tag, along the lines of this: <meta http-equiv="refresh" content="3;http://example.com/download.epl2" /> I specify that the document has a content-type of application/x-epl2, and I have associated .epl2 files on my computer with a program that silently sends them to the printer. I have put the website into my trusted sites zone. Currently Internet Explorer pops up the "Open, Save, Cancel" dialog box with no option to automatically open the file. Is there a setting in IE6/7/8 that I can use to have IE just open the file without prompting?

  • How to find good looking font color if background color is known?

    - by Mecki
    There seem to be so many color wheel, color picker, and color matcher web apps out there, where you give one color and the they'll find a couple of other colors that will create a harmonic layout when being used in combination. However most of them focus on background colors only and any text printed on each background color (if text is printed at all in the preview) is either black or white. My problem is different. I know the background color I want to use for a text area. What I need help with is choosing a couple of colors (the more, the merrier) I can use as font colors on this background. Most important is that the color will make sure the font is readable (contrast not being too low, also maybe not being too high to avoid that eyes are stressed) and of course that the combination of foreground and background just looks good. Anyone being aware of such an application? I'd prefer a web application to anything I have to download. Thanks.

  • Prevent query string manipulation by adding a hash?

    - by saille
    To protect a web application from query string manipulation, I was considering adding a query string parameter to every url which stores a SHA1 hash of all the other query string parameters & values, then validating against the hash on every request. Does this method provide strong protection against user manipulation of query string values? Are there any other downsides/side-effects to doing this? I am not particularly concerned about the 'ugly' urls for this private web application. Url's will still be 'bookmarkable' as the hash will always be the same for the same query string arguments. This is an ASP.NET application.

  • Load vs Get in Nhibernate

    - by Quintin Par
    The master page in my web application does authentication and loads up the user entity using a Get. After this whenever the user object is needed by the usercontrols or any other class I do a Load. Normally nhibernate is supposed to load the object from cache or return the persistent loaded object whenever Load of called. But this is not the behavior shown by my web application. NHprof always shows the sql whenever Load is called. How do I verify the correct behavior of Load? I use the S#arp architecture framework.

  • Can I use UIPerformance grails plugin and host my static resources in another domain?

    - by fabien7474
    The UIPerfomance plugin is an easy way to speed up your web pages by applying some of the best practices rules from Yahoo performance team (like minifying, setting a far-future expires header, versioned images...) Unfortunately I didn't find a way to store the static resources in a location outside of the webapplication which has his own advantages ( smaller WAR sizes, better optimize cookieless server, static resources served faster by a highly optimized native httpd, no need to redeploy WAR when updating static resources..). So my question is: is it possible to use this great plugin with static resoures stored outside the web application? And if yes, how?

  • Is it possible to put binary image data into html markup and then get the image displayed as usual i

    - by Joern Akkermann
    It's an important security issue and I'm sure this should be possible. A simple example: You run a community portal. Users are registered and upload their pictures. Your application gives security rules whenever a picture is allowed to be displayed. For example users must be friends on each sides by the system, in order that you can view someone else's uploaded pictures. Here comes the problem: it is possible that someone crawls the image directories of your server. But you want to protect your users from such attacks. If it's possible to put the binary data of an image directly into the HTML markup, you can restrict the user access of your image dirs the user and group your web application runs of and pass the image data to your Apache user and group directly in the HTML. The only possible weakness then is the password of the user that your web app runs as. Is there already a possibility?

  • What does Visual Studio 2008 do when I add an assembly reference?

    - by tk-421
    When I add a reference to an assembly (living in the GAC) to web.config in an ASP.NET project, what does Visual Studio do? [This is related to an earlier question pertaining to BusinessObjects: http://stackoverflow.com/questions/2379615/ ] When I add "CrystalDecisions.Enterprise" and "CrystalDecisions.Enterprise.Framework" to the assemblies element in web.config, VS thinks long and hard about it, locking me out for a couple of minutes while it scrutinizes the newcomers. What is it doing during this time? I Googled this but came up empty. I can make some educated guesses (IntelliSense integration, perhaps?) but would ideally like to find some documentation describing exactly what's going on. Ultimately I'm hoping to learn why these BO references are making VS take several minutes to open my projects (I struck out on the SAP forums).

  • Check which nodes of Beowulf HPC cluster system are free from PHP app?

    - by Skuja
    I am working on my diploma thesis project. I have access to 32Node Dell poweredge HPC cluster system with Linux(Debian i think) installed on it. My first goal is to create web (PHP) app where logged users could see free and busy nodes, turn them on and off. I am planning to do something like this - write some cron daemon that would run every 30seconds or other interval, and it could run ping utility for each node to find out if it is on or off, then write results to some file. Then from my web app i could read the info. Will it be a good solution? What existing for node management solutions are there?

  • Learn Obj-C Memory Management

    - by Joshua Brickner
    I come from a web development background. I'm good at XHTML, CSS, JavaScript, PHP and MySQL, because I use all of those technologies at my day job. Recently I've been tinkering with Obj-C in Xcode in the evenings and on weekends. I've written code for both the iPhone and Mac OS X, but I can't wrap my head around the practicalities of memory management. I understand the high-level concepts but am unclear how that plays out in implementation. Web developers typically don't have to worry about these sorts of things, so it is pretty new to me. I've tried adding memory management to my projects, but things usually end up crashing. Any suggestions of how to learn? Any suggestions are appreciated.

  • Handling Custom Protocols

    - by nomad311
    I'm looking to respond to an event from a web browser, hopefully any web browser. I'm working solely on windows and I came to the conclusion a custom protocol (I.E. myprot://collection/of/strings) is the best approach here (any objections?). But, handling an instance of this protocol seems to be a little less straight-forward. All I need is that collection of strings auto-magically passed to my already running application! (the app will only respond to these links while in a specific waiting state) So answer me this, if you can, Whats the 'popular' method of handling them or better yet Whats the 'best' (subjective - I know) way to do it? Although your answers don't need to be specific to my language, I am using Delphi for development. Thanks!

  • ASP.NET 1.0 site error after upgrade to VS.NET 2010

    - by Keith
    Help. I installed VS.NET 2010 and now my existing ASP.NET MVC application won't run. I checked that the 1.0 version of System.Web.Mvc is still referenced but when I browse my application, I get an error like this: "Compiler Error Message: CS1579: foreach statement cannot operate on variables of type 'object' because 'object' does not contain a public definition for 'GetEnumerator'". My partial view has this declaration: <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<List<ProductModel" %> //various import statements <div <% foreach (var category in Model.Categories) { % <span<%= category.Name %</span <span<%= category.Market%</span <% } % </div For what it's worth, the source view shows ViewUserControl in red and gives a tool tip reading "Cannot resolve symbol 'ViewUserControl'". My working code didn't change, the only delta is that I upgraded to VS.NET 2010 (which includes MVC 2.0); I'm sure something is not referenced correctly but I cannot figure out what's going on.

  • Adding NavigationControl to a TabBar Application containing UITableViews

    - by kungfuslippers
    Hi, I'm new to iPhone dev and wanted to get advice on the general design pattern / guide for putting a certain kind of app together. I'm trying to build a TabBar type application. One of the tabs needs to display a TableView and selecting a cell from within the table view will do something else - maybe show another table view or a web page. I need a Navigation Bar to be able to take me back from the table view/web page. The approach I've taken so far is to: Create an app based around UITabBarController as the rootcontroller i.e. @interface MyAppDelegate : NSObject <UIApplicationDelegate> { IBOutlet UIWindow *window; IBOutlet UITabBarController *rootController; } Create a load of UIViewController derived classes and associated NIBs and wire everything up in IB so when I run the app I get the basic tabs working. I then take the UIViewController derived class and modify it to the following: @interface MyViewController : UIViewController<UITableViewDataSource, UITableViewDelegate> { } and I add the delegate methods to the implementation of MyViewController - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return 2; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; } if (indexPath.row == 0) { cell.textLabel.text = @"Mummy"; } else { cell.textLabel.text = @"Daddy"; } return cell; } Go back to IB , open MyViewController.xib and drop a UITableView onto it. Set the Files Owner to be MyViewController and then set the delegate and datasource of the UITableView to be MyViewController. If I run the app now, I get the table view appearing with mummy and daddy working nicely. So far so good. The question is how do I go about incorporating a Navigation Bar into my current code for when I implement: - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath() { // get row selected NSUInteger row = [indexPath row]; if (row == 0) { // Show another table } else if (row == 1) { // Show a web view } } Do I drop a NavigationBar UI control onto MyControllerView.xib ? Should I create it programmatically? Should I be using a UINavigationController somewhere ? I've tried dropping a NavigationBar onto my MyControllerView.xib in IB but its not shown when I run the app, only the TableView is displayed.

  • Visual Studio ASP.Net MVC undo set as start page action

    - by kingrichard2005
    I have an web application that I'm working on, it was working fine until my curiosity got the better of me and I right-clicked on a view and chose Set As Start Page option. Now, whenever I run my application it takes me to the Resource Not Found error page. I have the default register route set in my Global config route which was working fine before. I notice that the URL now reads: http://localhost:1234/Views/User/Login.aspx instead of http://localhost:1234/ like it was before. I'm not sure how to undo this action or what was changed, I've looked in my web.config file but I'm not sure what to look for exactly, Help is appreciated.

  • codemirror fails when adding </textarea> tag inside it

    - by Jorre
    I'm using codemirror http://marijn.haverbeke.nl/codemirror/ to let users create their own web templates inside a web application. Codemirror works great, except for the time that users have put a tag inside their source code. When I load that up inside code mirror, it breaks everything in the source code that follows after because it thinks my codemirror text area is closed. I'm using the following way to launch codemirror: CodeMirror.fromTextArea('code') It works great on my existing textarea "code" except when users add inside their templates (in the codemirror textarea). Any help is much appreciated!

  • Best way to implement a 404 in ASP.NET

    - by Ben Mills
    I'm trying to determine the best way to implement a 404 page in a standard ASP.NET web application. I currently catch 404 errors in the Application_Error event in the Global.asax file and redirect to a friendly 404.aspx page. The problem is that the request sees a 302 redirect followed by a 404 page missing. Is there a way to bypass the redirect and respond with an immediate 404 containing the friendly error message? Does a web crawler such as Googlebot care if the request for a non existing page returns a 302 followed by a 404?

  • Javascript substrings multiline replace by RegExp

    - by Radek Šimko
    Hi, I'm having some troubles with matching a regular expression in multi-line string. <script> var str="Welcome to Google!\n"; str = str + "We are proud to announce that Microsoft has \n"; str = str + "one of the worst Web Developers sites in the world."; document.write(str.replace(/.*(microsoft).*/gmi, "$1")); </script> http://jsbin.com/osoli3/3/edit As you may see on the link above, the output of the code looks like this: Welcome to Google! Microsoft one of the worst Web Developers sites in the world. Which means, that the replace() method goes line by line and if there's no match in that line, it returns just the whole line... Even if it has the "m" (multiline) modifier...

  • linq-to-sql "an attempt has been made to attach or add an entity that is not new"?

    - by Curtis White
    I've been getting several errors: cannot add an entity with a key that is already in use An attempt has been made to attach or add an entity that is not new, perhaps having been loaded from another datacontext In case 1, this stems from trying to set the key for an entity versus the entity. In case 2, I'm not attaching an entity but I am doing this: MyParent.Child = EntityFromOtherDataContext; I've been using using the pattern of wrap everything with a using datacontext. In my case, I am using this in a web forms scenario, and obviously moving the datacontext object to a class wide member variables solves this. My questions are thus 2 fold: How can I get rid of these errors and not have to structure my program in an odd way or pass the datacontext around while keeping the local-wrap pattern? I assume I could make another hit to the database but that seems very inefficient. Would most people recommend that moving the datacontext to the class wide scope is desirable for web pages?

  • Connect to development server via switch?

    - by letseatfood
    I apologize upfront if this isn't appropriate for superuser. I asked it on serverfault and was told it was too general for that site. I have a laptop with Vista and it receives it's internet connection wireless. I have an old desktop with Ubuntu 10.04 Server Edition installed and it is setup as a development server with Apache, MySQL, and PHP. This works well, with the server having a static IP address. The server is connected to the router via an Ethernet cable. Is it possible to disconnect the cable that is currently connecting the server and the router, then connect the server and workstation to a switch, so that I am still able to connect to the server via web browser from the workstation? I am trying to eliminate the long ethernet cable connecting the server to the router in the other room. I already have a switch, that is why I asked specifically about it. Thanks and I will be more than happy to clarify!

    I am looking to get my hands wet in Java Web Services. Apache CXF and Axis2 seem to be in demand a lot. I googled a bit for finding a good Axis2 book that has lot of working examples. some books like Quick Start Apache Axis 2 seem to have bad reviews on Amazon and titles like Web Services with Apache CXF and Axis2 seem to lack working examples. I want to get opinion from people who currently work with Axis2 and have read a book or two on the subject. Which is a good book for an Axis2 n00b.
