• Simple RIA backend

  - by Jeremy

  I'm creating a prototype for a java web application. Frontend is a Swing-based java applet. Backend should be a type of web-service, that is called by applet. Backend should run inside a servlet container and should have its own security (username/password) database. I know, that Tomcat has its own user database (realm), but the app should have own. Web-services, in turn, carrying out app logic and database access (via Hibernate). I'm a newbie for a web development and I'm getting lost in a huge amount of the java web frameworks. Even just reading 'introduction' and 'getting started' documents takes a lot of time. So I need an advice which framework(s) are suitable for the task and not very complex for a quick start. Thank you

• Using sessions & session variables in a PHP Login Script

  - by user1325291

  I have just finished creating an entire login and register systsem in PHP, but my problem is I haven't used any sessions yet. (Like, there's not the word "session" in the entire script). I'm kind of a newbie in PHP and I've never used sessions before. What I want to do it, after the user registers and fills out the login form, they will still stay on the same page. So, like one half of the page will be if the session is logged_in and the other part will be else (the user is not logged in so display the login form). I also want to create session variables which will hold the username and password given at login. Thanks in advance! BTW this is my website - CP Cheats

• Should I start with Trac 0.12 ?

  - by mree

  I'm going to start using Trac for the first time. From what I've gathered, the latest 0.12 is capable of supporting multiple project easily (which is something I will need since I got about 5 projects). However, it seems 0.12 is still in the development (0.12-dev). So, my question is, is it good enough for a newbie in Trac like me to use it? Does anyone has any experience using it ? It will be installed on a Linux server. BTW, I'll only be using the basic functions such as svn browser, wiki, tickets and others.

• How do I prevent an https response from throwing an AuthenticationException with Fiddler running?

  - by Ichabod Clay

  Relative newbie to C# here :) I'm currently creating a web link scraper and having issues with the responses I'm getting when trying to login to the website via my program. I'm trying to use Fiddler to see if my program is sending the proper data, but my program is throwing an AuthenticationException when trying to get a response from the site with Fiddler running. The requests are being sent over HTTPS and Fiddler's certificate is the cause of the excepting being thrown. My question is, what can I implement into my program to have it disregard the certificate authentication? As far as my program goes, the requests and responses are being handled by HttpWebRequest and HttpWebResponse classes.

  - by LuckyShot

  Hi guys, Quick newbie question here, how do I access totalResults?

• Regex to validate for Unique Well Identifier in rails

  - by Jasper502

  I am a regex newbie and can't seem to figure this one out. Here is a link to the required string formats: http://earth.gov.bc.ca/royp-bin/phcgi.exe?PH_QKC=DOCUWI&PH_APP=RMSprodApp&PH_HTML=DOCUWI.htm For example: 100041506421W500 = 1+0+{01-16}+{01-36}+{001-129}+{01-36}+W+{1-6}+0+{0-9} I tried this: ^10[0|2-9]{1}0*([1-9]|1[0-6])0*([1-9]|[12][0-9]|3[0-6])0*([1-9][0-9]|1[0-2][0-9])0*([1-9]|[12][0-9]|3[0-6])W[1-6]0[0-9]$ In a regex validator and it sort of works except that 1041506421W500 and 10000000041506421W500 validates. The entire string can only be 16 characters long. I am pretty sure I am missing something obvious here regarding the leading zeros. Tried the NTS format and running into the same sort of problems.

• How do I do import hooks in IronPython/Silverlight?

  - by ahlatimer

  I'm extending TryPython to (along with various other things) allow users to save a file and subsequently import that file. TryPython overloads the built in file operations, so I need to know what parts of import need to hooked into in order for import to use the overloaded file operations. Really, a basic overview of IronPython's import when used in Silverlight would be extremely helpful. I don't need a complete working solution (although I won't stop you from writing one! :). I'm a Python newbie, and I really have no idea where to even begin. Thanks!

• Creation of database in Oracle

  - by macha

  Hello, I am a newbie to Oracle, and I have used MySQL for most of the time. So now for testing scripts, I was just planning to create a database, but from the resources I have found on google, it doesn't look as simple it is maybe in mysql or in sqlserver. I just need to create a database, say "CREATE DATABASE TESTDB";. That is it, but of the resources I have found, it seems I need to create an instance identifier, decide an authentication method, create an initialization file etc. Do I really have to do all this or am I using the wrong resources. I just need to create a database and add a few tables into it, just to check my connection string etc. I need to check if I am able to connect to my web server.

• How do I secure password parameters in RESTful web service URIs?

  - by adam

  i'm a newbie to server-side programming, so please forgive me if this gets messy. i've been contracted to create a web service to allow authenticated users to access a database. users have to enter a login and password. been reading and reading about REST vs SOAP, and i thought i'd settled on a RESTful design when i came across this statement: "Data that needs to be secure should not be sent as parameters in URIs." this seems like a major demerit against a RESTful approach. i'm aware that with https the password would be encrypted to prevent man-in-the-middle interception, but that leaves the server logs and client history as possible exposure points. is there a RESTful solution out there for this problem, or do i need to go SOAPy? any advice appreciated.

• PHP: How to check for response code?

  - by Tom

  Hi, I'm a relative PHP newbie implementing a PayPal IPN listener and all seems to be working fine, except I dont really know how to check for a response code. I've tried something ugly with cURL but it doesn't work at all (I'm not understanding cURL). I've tried this piece of code that I grabbed from somewhere on the net: $fp = fsockopen('ssl://www.sandbox.paypal.com', 443, $errno, $errstr, 30); $response_headers = get_headers($fp); $response_code = (int)substr($headers[0], 9, 3); ... but it's not working (returns $response_code = 0). So right now, I'm debugging my IPN code without checking for a Response 200. Can anyone more experienced advise me on what's the proper/simple way to check this? Thanks

• Getting a NullReferenceException Error when invoking a Select File Dialog Box

  - by codingguy3000

  Hey everyone This is a real newbie question. I have simple app that selects a picture and display's that picture in a PictureBox. I decided to mess with the Opacity Attribute so I added a timer and created this cool effect where the Main Form's Opacity is increased by 20% every 400 miliseconds. The problem is that now when I click the button that invokes the Select File Dialog Box I'm getting a NullReferenceException error. private void tmrClock_Tick(object sender, EventArgs e) { if (ViewerForm.ActiveForm.Opacity != 1) { ActiveForm.Opacity = ActiveForm.Opacity + .20; } } The error message is pointing to the if statement. What am I doing wrong? Thanks

• Maven overlay with war not generated by maven

  - by dnc253

  I'm pretty new to Maven, so I apologize if this is a newbie question. We are trying to integrate a 3rd-party app into ours. This 3rd-party functionality is delivered to us as a war file. As part of this integration, I want to add some extra jars and and a properties file. Googling around, I discovered overlays. However, in all the examples I've seen, it looks the the wars that are being overlayed, were themselves generated by Maven, and thus Maven can figure out dependencies, conflicts, etc. between the two. I'm just wondering if there's a way for me to overlay this 3rd-party war with this extra stuff I want. If so, what would that look like in the pom.xml?

(I´m a newbie) jQuery 1.4.2 and the jQuery Form Plugin 2.43 is present. tnx $(document).ready(function() { var options = { target: '#output2', url: https://graph.facebook.com/<%=fbUid%>/feed, type: post, clearForm: true // clear all form fields after successful submit //dataType: null // 'xml', 'script', or 'json' (expected server response type) //resetForm: true // reset the form after successful submit // $.ajax options can be used here too, for example: //timeout: 3000 }; // bind to the form's submit event $('#fbPostStatus').submit(function() { // inside event callbacks 'this' is the DOM element so we first // wrap it in a jQuery object and then invoke ajaxSubmit $(this).ajaxSubmit(options); // !!!
