  • Suggestions for designing large-scale Java webapp from the group up

    - by Chris Thompson
    Hi all, I'm about to start developing a large-scale system and I'm struggling with which direction to proceed. I've done plenty of Java web apps before and I have plenty of experience with servlet containers and GWT and some experience with Spring. The problem is most of my webapps have been thrown together just to be a proof of concept and what I'm struggling with is what set of frameworks to use. I need to have both a browser based application as well as a web service designed to support access from mobile devices (Android and iPhone for now). Ideally, I'd like to design this system in such a way that I don't end up rewriting all of my servlets for each client (browser and phone) although I don't mind having some small checks in there to properly format the data. In addition, although I'm the only developer now, that won't necessarily be the case down the road and I'd like to design something that scales well both with regards to traffic and number of developers (isn't just a nightmare to maintain). So where I am now is planning on using GWT to design the browser-based interface but I'm struggling with how to reuse that code with to present the interface (most likely xml) for the mobile devices. Using GWT RPC would, I think, make it relatively easy to do all of the AJAX in the browser, but might make generating xml for the mobile phones difficult. In addition, I like the idea of using something like Hibernate for persistence and Spring Security to secure the whole thing. Again, I'm not sure how well those will cooperate with GWT (I think Hibernate should be fine...) There's obviously a lot more to this than I've presented here, but I've tried to give you the 5-minute overview. I'm a bit stumped and was wondering if anybody in the community had any experience starting from this place. Does what I'm trying to do make sense? Is it realistic? I have no doubt I can make all of these frameworks speak the same language, I'm just wondering if it's worth my time to fight with them. Also, am I missing a framework that would be really beneficial? Thanks in advance and sorry for the relatively broad question... Chris

  • Problem running a simple EJB application

    - by Spi1988
    I am currently running a simple EJB application using a stateless Session Bean. I am working on NetBeans 6.8 with Personal Glassfish 3.0 and I have installed on my system both the Java EE and the Java SE. I don't know whether it is relevent but I am running Windows7 64-bit version. The Session Bean I implemented has just one method sayHello(); which just prints hello on the screen. When I try to run the application I'm getting the following error: pre-init: init-private: init-userdir: init-user: init-project: do-init: post-init: init-check: init: deps-jar: deps-j2ee-archive: MyEnterprise-app-client.init: MyEnterprise-ejb.init: MyEnterprise-ejb.deps-jar: MyEnterprise-ejb.compile: MyEnterprise-ejb.library-inclusion-in-manifest: MyEnterprise-ejb.dist-ear: MyEnterprise-app-client.deps-jar: MyEnterprise-app-client.compile: MyEnterprise-app-client.library-inclusion-in-manifest: MyEnterprise-app-client.dist-ear: MyEnterprise-ejb.init: MyEnterprise-ejb.deps-jar: MyEnterprise-ejb.compile: MyEnterprise-ejb.library-inclusion-in-manifest: MyEnterprise-ejb.dist-ear: pre-pre-compile: pre-compile: do-compile: post-compile: compile: pre-dist: post-dist: dist-directory-deploy: pre-run-deploy: Starting Personal GlassFish v3 Domain Personal GlassFish v3 Domain is running.

  • properly setting email subject line delivered from email form

    - by DC1
    I have a email form for my website but here is the issue: when i receive an email, the subject line in my inbox shows whatever the user inputted as subject in the form. id like to override that so that whenever an email comes in. the subject in the email header is always "an inquiry from your website". In the message body, sure i don't mind their specific subject they entered but when I receive an email, id like consistency in my inbox. this is the current code: <?php session_start(); if(isset($_POST['Submit'])) { if( $_SESSION['chapcha_code'] == $_POST['chapcha_code'] && !empty($_SESSION['chapcha_code'] ) ) { $youremail = 'xxxxxxxxx'; $fromsubject = 'An inquiry from your website'; $title = $_POST['title']; $fname = $_POST['fname']; $lname = $_POST['lname']; $mail = $_POST['mail']; $address = $_POST['address']; $city = $_POST['city']; $zip = $_POST['zip']; $country = $_POST['country']; $phone = $_POST['phone']; $subject = $_POST['subject']; $message = $_POST['message']; $headers = "From: $nome <$mail>\r\n"; $to = $youremail; $mailsubject = 'Message received from'.$fromsubject.'

  • ASP.NET - working with GridView Programmatically

    - by JMSA
    I am continuing from this post. After much Googling, I have come up with this code to edit cells programmatically: using System; using System.Data; using System.Configuration; using System.Collections; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Web.UI.HtmlControls; using Ice_Web_Portal.BO; namespace GridView___Test { public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { GridView1.DataSource = Course.GetCourses(); GridView1.DataBind(); } protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e) { GridViewRow row = GridView1.Rows[e.NewEditIndex]; GridView1.EditIndex = e.NewEditIndex; GridView1.DataSource = Course.GetCourses(); GridView1.DataBind(); } protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e) { TextBox txtID = (TextBox)GridView1.Rows[e.RowIndex].Cells[1].Controls[0]; TextBox txtCourseCode = (TextBox)GridView1.Rows[e.RowIndex].Cells[2].Controls[0]; TextBox txtCourseName = (TextBox)GridView1.Rows[e.RowIndex].Cells[3].Controls[0]; TextBox txtCourseTextBookCode = (TextBox)GridView1.Rows[e.RowIndex].Cells[4].Controls[0]; Course item = new Course(); item.ID = Convert.ToInt32(txtID.Text); item.CourseCode = txtCourseCode.Text; item.CourseName = txtCourseName.Text; item.TextBookCode = txtCourseTextBookCode.Text; bool success = Course.Update(item); labMessage.Text = success.ToString(); GridView1.EditIndex = -1; GridView1.DataSource = Course.GetCourses(); GridView1.DataBind(); } } } But 2 problems are happening. (1) I need to press command buttons twice to Edit/Update. (2) Changes in the cell values are not updated in the database. I.e. edited cell values are not committing. Can anyone give me a solution?

  • Spring AOP pointcut that matches annotation on interface

    - by seanizer
    Hello, this is my first post here, so I apologize in advance for any stupidity on my side. I have a service class implemented in Java 6 / Spring 3 that needs an annotation to restrict access by role. I have defined an annotation called RequiredPermission that has as its value attribute one or more values from an enum called OperationType: public @interface RequiredPermission { /** * One or more {@link OperationType}s that map to the permissions required * to execute this method. * * @return */ OperationType[] value();} public enum OperationType { TYPE1, TYPE2; } package com.mycompany.myservice; public interface MyService{ @RequiredPermission(OperationType.TYPE1) void myMethod( MyParameterObject obj ); } package com.mycompany.myserviceimpl; public class MyServiceImpl implements MyService{ public myMethod( MyParameterObject obj ){ // do stuff here } } I also have the following aspect definition: /** * Security advice around methods that are annotated with * {@link RequiredPermission}. * * @param pjp * @param param * @param requiredPermission * @return * @throws Throwable */ @Around(value = "execution(public *" + " com.mycompany.myserviceimpl.*(..))" + " && args(param)" + // parameter object " && @annotation( requiredPermission )" // permission annotation , argNames = "param,requiredPermission") public Object processRequest(final ProceedingJoinPoint pjp, final MyParameterObject param, final RequiredPermission requiredPermission) throws Throwable { if(userService.userHasRoles(param.getUsername(),requiredPermission.values()){ return pjp.proceed(); }else{ throw new SorryButYouAreNotAllowedToDoThatException( param.getUsername(),requiredPermission.value()); } } The parameter object contains a user name and I want to look up the required role for the user before allowing access to the method. When I put the annotation on the method in MyServiceImpl, everything works just fine, the pointcut is matched and the aspect kicks in. However, I believe the annotation is part of the service contract and should be published with the interface in a separate API package. And obviously, I would not like to put the annotation on both service definition and implementation (DRY). I know there are cases in Spring AOP where aspects are triggered by annotations one interface methods (e.g. Transactional). Is there a special syntax here or is it just plain impossible out of the box. PS: I have not posted my spring config, as it seems to be working just fine. And no, those are neither my original class nor method names. Thanks in advance, Sean PPS: Actually, here is the relevant part of my spring config: <aop:aspectj-autoproxy proxy-target-class="false" /> <bean class="com.mycompany.aspect.MyAspect"> <property name="userService" ref="userService" /> </bean>

  • How to call a JavaScript function from one frame to another in Chrome/Webkit with file protocol

    - by bambax
    I have developed an application that has a list of items in one frame; when one clicks on an item it does something in another frame (loads an image). This used to work fine in all browsers, including Chrome 3; now it still works fine in Firefox but in recent versions of Chrome (I believe since 4) it throws this error: Unsafe JavaScript attempt to access frame with URL (...) from frame with URL (...). Domains, protocols and ports must match. This is obviously a security "feature" but is it possible to get around it? Here is a simple test: index.html: <html> <frameset cols="50%,50%"> <frame src="left.html" name="left"/> <frame src="right.html" name="right"/> </frameset> </html> left.html: <html> <body> <a href="javascript:parent.right.test('hello');">click me</a> </body> </html> right.html: <html> <body> <script> function test(msg) { alert(msg); } </script> </body> </html> The above works in Firefox 3.6 and Chrome 3 but in Chrome 5 it throws the above error... Edit: added the @cols attribute to the frameset element in fact it works in Chrome if and only if the pages are served with the http protocol (and from the same domain) but my problem is when pages are local and served from a file:// protocol. Then it works in Firefox (all versions) and Chrome 3 but not Chrome 5 (I don't have Chrome 4 so I'm not shure about that specific version (and don't know if it's even possible to download a specific Chrome version?) -- but for Chrome 5 I'm very sure it doesn't work).

  • What does N years of experience with a language really mean?

    - by marcgg
    I've been looking at jobs descriptions since I'm graduating soon and looking for a job and what's always coming back - I'm not teaching you anything - is the "N years of experience in this language". It has been discussed in this question that if you work professionally with let's say Ruby for 2 years, but during these two years you also did some C# and PHP and were actually coding in Ruby 50% of the time. Do you say you have 1 year of experience in Ruby? 2 years? Another issue that hasn't been reviewed in the other post is for "non-professional experience". I'll give you a personal example: I've been working with Ruby on Rails since 2004 while at school. I did a lot of personal projects and school projects using this technology. I also used Rails in 2 6-month internships. Do I have 5 years of Rails experience (2004-now)? Do I have 1 year(2 internships)? Do I have nothing? I feel like I don't deserve the credit for 5 years, because the first years I wasn't working a lot with rails, but since last year I launched some websites and invested myself a lot in this technology and just saying 1 year doesn't really reflect how much I know the technology... Another example: I Learned C++ at school and did 1 big project with it (2-3 month of work and a semester of classes). I never used it in a company but I'd be able to be productive fairly quickly if I had to work on a C++ project and I have a good grasp of the concepts. Do I have no experience? 3 months? 6 months? ... something else? What I'm really trying to do is to find a way to present my skill set in a way that is compliant to what recruiters expect. I also don't want to end up at an interview that would go something like this... Recruiter (finding out the horrible truth): Oh but you said that you had 2 years of experience with this when you have none! / slaps me in the face / Me (in pain): Oh! The irony! Recruiter (yelling): Get out of my office / calls security, punches me in the throat /

  • how to save xml files using Javascript?

    - by user311884
    Dear friends, I tried to 1) load an xml file using javascript as an object, say "note.xml" 2) then save the object to a new xml file, say "note_new.xml" I did 1) but failed 2) I tried to use method save() to do 2). After my failure, I checked ms site and they said save() is not supported.... could some one enlighten me how to do the save? thank you! here is the code: <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/> </head> <body> <h1>W3Schools Internal Note</h1> <p><b>To:</b> <span id="to"></span><br /> <b>From:</b> <span id="from"></span><br /> <b>Message:</b> <span id="message"></span> <script type="text/javascript"> if (window.ActiveXObject){ alert("there is ActiveXObject"); var xmlDoc = new ActiveXObject("Microsoft.XMLDOM"); xmlDoc.async=false; xmlDoc.load("note.xml"); }else{ alert("i am not withActiveXObject!"); xhttp=new XMLHttpRequest(); xhttp.open("GET","note.xml",false); xhttp.send(""); xmlDoc=xhttp.responseXML; } xmlDoc.save("note_new.xml"); </script> </body> </html> update: seems this is related to security issue. I appologize to those experienced programmers for my putting this question in a rush because it seems a newbie question.

  • Using PHP's IMAP library triggers Kaspersky's Antivirus

    - by TMG
    Hello, I just started today working with PHP's IMAP library, and while imap_fetchbody or imap_body are called, it is triggering my Kaspersky antivirus. The viruses are Trojan.Win32.Agent.dmyq and Trojan.Win32.FraudPack.aoda. I am running this off a local development machine with XAMPP and Kaspersky AV. Now, I am sure there are viruses there since there is spam in the box (who doesn't need a some viagra or vicodin these days?). And I know that since the raw body includes attachments and different mime-types, bad stuff can be in the body. So my question is: are there any risks using these libraries? I am assuming that the IMAP functions are retrieving the body, caching it to disk/memory and the AV scanning it sees the data. Is that correct? Are there any known security concerns using this library (I couldn't find any)? Does it clean up cached message parts perfectly or might viral files be sitting somewhere? Is there a better way to get plain text out of the body than this? Right now I am using the following code (credit to Kevin Steffer): function get_mime_type(&$structure) { $primary_mime_type = array("TEXT", "MULTIPART","MESSAGE", "APPLICATION", "AUDIO","IMAGE", "VIDEO", "OTHER"); if($structure->subtype) { return $primary_mime_type[(int) $structure->type] . '/' .$structure->subtype; } return "TEXT/PLAIN"; } function get_part($stream, $msg_number, $mime_type, $structure = false, $part_number = false) { if(!$structure) { $structure = imap_fetchstructure($stream, $msg_number); } if($structure) { if($mime_type == get_mime_type($structure)) { if(!$part_number) { $part_number = "1"; } $text = imap_fetchbody($stream, $msg_number, $part_number); if($structure->encoding == 3) { return imap_base64($text); } else if($structure->encoding == 4) { return imap_qprint($text); } else { return $text; } } if($structure->type == 1) /* multipart */ { while(list($index, $sub_structure) = each($structure->parts)) { if($part_number) { $prefix = $part_number . '.'; } $data = get_part($stream, $msg_number, $mime_type, $sub_structure,$prefix . ($index + 1)); if($data) { return $data; } } // END OF WHILE } // END OF MULTIPART } // END OF STRUTURE return false; } // END OF FUNCTION $connection = imap_open($server, $login, $password); $count = imap_num_msg($connection); for($i = 1; $i <= $count; $i++) { $header = imap_headerinfo($connection, $i); $from = $header->fromaddress; $to = $header->toaddress; $subject = $header->subject; $date = $header->date; $body = get_part($connection, $i, "TEXT/PLAIN"); }

  • Google Bookmarks Accelerator for IE8

    - by MACHiNESMiTH
    To Editors: Sorry, I didnt realise the question thing till you pointed it out. Also I didn't know about the appengine tag, I'm assuming it was selected by mistake from that JS autosuggestion box (it usually happens with me, I run a P3) my apologies for that too. I've edited it now, if it doesnt work let me know. Hi all, I'm making (or at least trying to make) a Google bookmarks accelerator for IE8, but I keep running into "Internet Explorer could not install this accelerator. There was a problem with the Accelerator's information." Does anyone know why this is happening? Here is the code I've made <?xml version="1.0" encoding="UTF-8" ?> <os:openServiceDescription xmlns="http://www.microsoft.com/schemas/openservicedescription/1.0"> <os:homepageUrl>http://www.google.com/bookmarks</os:homepageUrl> <os:display> <os:description>Add this page to GoogleBookmarks</os:description> <os:name>Add to GoogleBookmarks</os:name> <os:icon>http://www.google.com/favicon.ico</os:icon> </os:display> <os:activity category="Bookmarks"> <os:activityAction context="document"> <os:execute method="get" action="http://www.google.com/bookmarks/mark?op=add&output=popup"> <os:parameter name="bkmk" value="{documentUrl}" /> <os:parameter name="title" value="{documentTitle}" /> <os:parameter name="annotation" value="{selection}" /> </os:execute> </os:activityAction> </os:activity> </os:openServiceDescription> These are the references I used: MSDN Developers Guide MSDN Format Specification Unofficial Google API (used as a look up so far) and yes i know that I cannot send document variables between schemes (HTTP - HTTPS, for example) or between servers in different security zones (Intranet - Internet etc) Also, if this is the wrong place, what are the recommended sites and/or forums for xml related posts? (not really questions - but more like full blown detailed rant like posts) Thanks

  • Update tile notifcation with XML returned by web service

    - by tempid
    I have a Metro app in C# & XAML. The tile is updated periodically and I've used WebAPI to serve the tile notification XML. So far so good. I was then told that I cannot use WebAPI as the server that I was planning to host it on does not have .NET 4.5. No plans to install it anytime soon either. I had to change the WebAPI to a plain old Web service (.NET 3.5) which does the same thing - return tile notification XML. I've enabled HTTP-GET (I know, security concern) and was able to invoke the webservice like this - http://server/TileNotifications.asmx/[email protected] But ever since I made the switch, the tiles are not being updated. I've checked Fiddler and made sure the app is hitting the webservice and the XML is being returned correctly. But the tiles are not updated. If I replace it with the WebAPI, the tiles are updated. Do I need to do anything special with the web services? like decorating the web method with a custom attribute? Here's my web service code - [WebMethod] public XmlDocument GetTileData(string user) { // snip var xml = new XmlDocument(); xml.LoadXml(string.Format(@"<tile> <visual> <binding template='TileWideSmallImageAndText02'> <image id='1' src='http://server/images/{0}_wide.png'/> <text id='1'>Custom Field : {1}/text> <text id='2'>Custom Field : {2}</text> <text id='3'>Custom Field : {3}</text> </binding> <binding template='TileSquarePeekImageAndText01'> <image id='1' src='http://server/images/{0}_square.png'/> <text id='1'>Custom Field</text> <text id='2'>{1}</text> </binding> </visual> </tile>", value1, value2, value3, value4)); return xml; }

  • Installing Windows on HP Proliant Servers without SmartStart

    - by Fitzroy
    I have a PXE server for deploying Windows XP and Windows 7 to workstations. The process is as follows: Boot the workstation from the NIC. Workstation sends a DHCP request. DHCP server responds with an IP address and the location of the PXE server. Workstation downloads WinPE image file from PXE server via TFTP Workstation stores WinPE image file in memory and executes it. Once booted into WinPE, I connect to a network share to gain access to either the Windows XP or Windows 7 installation files. A custom script is launched to guide you through the process of formatting and partitioning the hard drive(s) (using DISKPART and FORMAT). Another custom script asks for details such as the hostname to assign to the workstation. The answers provided are used to build an unattended answer file (SIF [Setup Information File] for WinXP and XML for Win7). The Windows setup EXE is launched, passing the unattended answer file to it as a parameter. The Windows XP and Windows 7 installation sources have been customised to include the drivers for our Dell workstations. They also run a number of scripts upon first booting up to install software packages. This process works very well for our workstations and I would now like to use it for building our servers too. The vast majority of our servers are HP Proliant DL360 G6, DL380 G5 and DL380 G6. They’re running Windows Server 2003 (various editions) or 2008 (various editions). To date, we have always built the HP Proliant servers using the SmartStart CD provided. SmartStart does three useful things for us: Setup RAID with HP Array Configuration Utility (ACU). Installs and configures SNMP Installs various HP Tools for Windows (HP Array Configuration Utility, HP Array Diagnostic Utility, HP Proliant Integrated Management Log Viewer, etc) Using SmartStart I have never had to manually download and install Windows drivers for network, sound, video, etc. I'm not sure if this is because SmartStart copies drivers from the CD during setup, or whether Windows just has the drivers natively in its driver CAB. If I abandon the SmartStart CD in favour of my PXE server I would have to do the following: As I wont have access to ACU, I'll configure the RAID (before booting to the PXE server) by pressing F8 (during the boot process) to access Option ROM Configuration for Arrays (ORCA). Installation of SNMP and the HP Tools will have to be installed once the Windows installation is complete using the Proliant Support Pack. Is this method OK? Is there anything that the SmartStart CD does that I'll be unable to do by other means? Are there any disadvantages to not using the SmartStart CD? Many thanks. UPDATE 05/01/12 I’ve been reading through the SmartStart Scripting Toolkit documentation. The scripting toolkit contains command line tools which work within WinPE and can such things as configure BIOS settings, configure an array and setup ILO. I’m personally not too bothered about configuring BIOS settings as I rarely deviate from the defaults (unless the server is to be a Hyper-V host). I’m not too fussed about being able to configure the array from within WinPE, as I’m happy to just press F8 and use Option ROM Configuration for Arrays (ORCA). Although, if it’s easy enough to do, I will explore this further, as it saves time if everything can be configured from within WinPE. One of the nice features all the tools possess is that you can pass input files to them. EG. Configure one server to your requirements, capture its configuration to a file (using the appropriate tool), you can then use the tool on other servers passing the input file with the captured configuration. Array controller drivers appear to be included with the toolkit along with example of how to incorporate them within a WinPE build. I suppose WinPE won’t be able to see logical volumes (I.E 2x physical disks in a RAID 1 configuration) without the array controller drivers? I mentioned in my post that SmartStart normally installs a bunch of Windows HP tools for you. I’ve had a look today, and if you run the SmartStart CD from within Windows all the tools can be installed. Therefore I can do this after the Windows installation is complete. The SmartStart CD appears to contain a lot Windows drivers. I can customise my Windows 2008 source to incorporate these drivers. However, I understand that incorporating an array controller driver is a little different to most drivers. I believe that you have to provide the driver during the very early stages of the Windows setup. I’m working through the Scripting Toolkit documentation to try and work this out...

  • PL/SQL pre-compile and Code Quality checks in an automatted build environment?

    - by Lars Corneliussen
    We build software using Hudson and Maven. We have C#, java and last, but not least PL/SQL sources (sprocs, packages, DDL, crud) For C# and Java we do unit tests and code analysis, but we don't really know the health of our PL/SQL sources before we actually publish them to the target database. Requirements There are a couple of things we wan't to test in the following priority: Are the sources valid, hence "compilable"? For packages, with respect to a certain database, would they compile? Code Quality: Do we have code flaws like duplicates, too complex methods or other violations to a defined set of rules? Also, the tool must run head-less (commandline, ant, ...) we wan't to do analysis on a partial code base (changed sources only) Tools We did a little research and found the following tools that could potencially help: Cast Application Intelligence Platform (AIP): Seems to be a server that grasps information about "anything". Couldn't find a console version that would export in readable format. Toad for Oracle: The Professional version is said to include something called Xpert validates a set of rules against a code base. Sonar + PL/SQL-Plugin: Uses Toad for Oracle to display code-health the sonar-way. This is for browsing the current state of the code base. Semantic Designs DMSToolkit: Quite general analysis of source code base. Commandline available? Semantic Designs Clones Detector: Detects clones. But also via command line? Fortify Source Code Analyzer: Seems to be focussed on security issues. But maybe it is extensible? more... So far, Toad for Oracle together with Sonar seems to be an elegant solution. But may be we are missing something here? Any ideas? Other products? Experiences?

  • Can't make my WCF extension work

    - by Sergio Romero
    I have a WCF solution that consists of the following class libraries: Exercise.Services: Contains the implementation classes for the services. Exercise.ServiceProxy: Contains the classes that are instantiated in the client. Exercise.HttpHost: Contains the services (*.svc files). I'm calling the service from a console application and the "first version" works really well so I took the next step which is to create a custom ServiceHostFactory, ServiceHost, and InstanceProvider so I can use constructor injection in my services as it is explained in this article. These classes are implemented in yet another class library: 4. Exercise.StructureMapWcfExtension Now even though I've modified my service this: <%@ ServiceHost Language="C#" Debug="true" Factory="Exercise.StructureMapWcfExtension.StructureMapServiceHostFactory" Service="Exercise.Services.PurchaseOrderService" %> I always get the following exception: System.ServiceModel.CommunicationException Security negotiation failed because the remote party did not send back a reply in a timely manner. This may be because the underlying transport connection was aborted. It fails in this line of code: public class PurchaseOrderProxy : ClientBase<IPurchaseOrderService>, IPurchaseOrderService { public PurchaseOrderResponse CreatePurchaseOrder(PurchaseOrderRequest purchaseOrderRequest) { return base.Channel.CreatePurchaseOrder(purchaseOrderRequest); //Fails here } } But that is not all, I added a trace to the web.config file and this is the error that appears in the log file: System.InvalidOperationException The service type provided could not be loaded as a service because it does not have a default (parameter-less) constructor. To fix the problem, add a default constructor to the type, or pass an instance of the type to the host. So this means that my ServiceHostFactory is never being hit, I even set a breakpoint in both its constructor and its method and they never get hit. I've added a reference of the StructureMapWcfExtension library to all the other ones (even the console client), one by one to no avail. I also tried to use the option in the host's web.config file to configure the factory like so: <serviceHostingEnvironment> <serviceActivations> <add service="Exercise.Services.PurchaseOrderService" relativeAddress="PurchaseOrderService.svc" factory="Exercise.StructureMapWcfExtension.StructureMapServiceHostFactory"/> </serviceActivations> </serviceHostingEnvironment> That didn't work either. Please I need help in getting this to work so I can incorporate it to our project. Thank you. UPDATE: Here's the service host factory's code: namespace Exercise.StructureMapWcfExtension { public class StructureMapServiceHostFactory : ServiceHostFactory { private readonly Container Container; public StructureMapServiceHostFactory() { Container = new Container(); new ContainerConfigurer().Configure(Container); } protected override ServiceHost CreateServiceHost(Type serviceType, Uri[] baseAddresses) { return new StructureMapServiceHost(Container, serviceType, baseAddresses); } } public class ContainerConfigurer { public void Configure(Container container) { container.Configure(r => r.For<IPurchaseOrderFacade>().Use<PurchaseOrderFacade>()); } } }

  • GLSL Error: failed to preprocess the source. How can I troubleshoot this?

    - by Brent Parker
    I'm trying to learn to play with OpenGL GLSL shaders. I've written a very simple program to simply create a shader and compile it. However, whenever I get to the compile step, I get the error: Error: Preprocessor error Error: failed to preprocess the source.

If it helps, I am trying to do this on a Acer Aspire One with an atom processor and integrated Intel video running the latest Ubuntu. It's not very powerful, but then again, this is a very simple shader. Thanks a lot for taking a look!

  • packet mmap send packet format

    I want to improve packet transmitting performance. Before that I used raw sockets and now I study packet_mmap. I have packets(frames) which I already captured from kernel module from another PC, put to current PC and now I want to retransmit them to local interface with following forwarding. I have got example of packet_mmap, integrated it to my project, but I send fd_socket = socket(PF_PACKET, SOCK_RAW, htons(ETH_P_ALL)); memset(&my_addr, 0, sizeof(struct sockaddr_ll)); my_addr.sll_family = PF_PACKET; my_addr.sll_protocol = htons(ETH_P_ALL); strcpy(str_devname, "eth0"); strncpy(s_ifr.ifr_name, str_devname, sizeof(s_ifr.ifr_name)); ec = ioctl(fd_socket, SIOCGIFINDEX, &s_ifr); i_ifindex = s_ifr.ifr_ifindex; memset(&my_addr, 0, sizeof(struct sockaddr_ll)); my_addr.sll_family = AF_PACKET; my_addr.sll_protocol = ETH_P_ALL; my_addr.sll_ifindex = i_ifindex; bind(fd_socket, (struct sockaddr *) &my_addr, sizeof(struct sockaddr_ll) s_packet_req.tp_block_size = c_buffer_sz; s_packet_req.tp_frame_size = c_buffer_sz; s_packet_req.tp_block_nr = c_buffer_nb; s_packet_req.tp_frame_nr = c_buffer_nb; size = s_packet_req.tp_block_size * s_packet_req.tp_block_nr; if (setsockopt(fd_socket, SOL_PACKET, PACKET_TX_RING, (char *) &s_packet_req, sizeof(s_packet_req)) < 0) { perror("setsockopt: PACKET_TX_RING"); return; } if (c_sndbuf_sz) { printf("send buff size = %d\n", c_sndbuf_sz); if (setsockopt(fd_socket, SOL_SOCKET, SO_SNDBUF, &c_sndbuf_sz, sizeof(c_sndbuf_sz)) < 0){ perror("getsockopt: SO_SNDBUF"); exit(1); } } data_offset = TPACKET_HDRLEN - sizeof(struct sockaddr_ll); printf("data offset = %d bytes\n", data_offset); ps_header_start = (tpacket_hdr *) mmap(0, size, PROT_READ | PROT_WRITE, MAP_SHARED, fd_socket, 0); if (ps_header_start == (void*) -1) { perror("mmap"); exit(1); } Then I fill data ps_header = ((struct tpacket_hdr *) ((char *) ps_header_start + (c_buffer_sz * i_index))); if (!ps_header) { perror("ps_header") ; return NULL; } data = ((char*) ps_header) + data_offset; switch ((volatile uint32_t) ps_header->tp_status) { case TP_STATUS_AVAILABLE: printf("TP_STATUS_AVAILABLE, index=%d\n",i_index) ; memcpy(data, packet_data, size); pthread_mutex_lock(&index_locker) ; i_index++; pthread_mutex_unlock(&index_locker) ; if (i_index >= c_buffer_nb) { i_index = 0; first_loop = 0; } /* update packet len */ ps_header->tp_len = size; /* set header flag to USER (trigs xmit)*/ ps_header->tp_status = TP_STATUS_SEND_REQUEST; then I send ec_send = sendto(fd_socket, NULL, 0, 0, (struct sockaddr *) ps_sockaddr, sizeof(struct sockaddr_ll)); I have got no errors, ec_send=not null size of sended data. But there are no data routed to destination host. So, I ask - what data I should pass to ring buffer, now I include headers ip,tcp, should I include MAC header? - May be I have to set additional flags to route my packets.

  • Suggestions for designing large-scale Java webapp from the ground up

    - by Chris Thompson
    Hi all, I'm about to start developing a large-scale system and I'm struggling with which direction to proceed. I've done plenty of Java web apps before and I have plenty of experience with servlet containers and GWT and some experience with Spring. The problem is most of my webapps have been thrown together just to be a proof of concept and what I'm struggling with is what set of frameworks to use. I need to have both a browser based application as well as a web service designed to support access from mobile devices (Android and iPhone for now). Ideally, I'd like to design this system in such a way that I don't end up rewriting all of my servlets for each client (browser and phone) although I don't mind having some small checks in there to properly format the data. In addition, although I'm the only developer now, that won't necessarily be the case down the road and I'd like to design something that scales well both with regards to traffic and number of developers (isn't just a nightmare to maintain). So where I am now is planning on using GWT to design the browser-based interface but I'm struggling with how to reuse that code with to present the interface (most likely xml) for the mobile devices. Using GWT RPC would, I think, make it relatively easy to do all of the AJAX in the browser, but might make generating xml for the mobile phones difficult. In addition, I like the idea of using something like Hibernate for persistence and Spring Security to secure the whole thing. Again, I'm not sure how well those will cooperate with GWT (I think Hibernate should be fine...) There's obviously a lot more to this than I've presented here, but I've tried to give you the 5-minute overview. I'm a bit stumped and was wondering if anybody in the community had any experience starting from this place. Does what I'm trying to do make sense? Is it realistic? I have no doubt I can make all of these frameworks speak the same language, I'm just wondering if it's worth my time to fight with them. Also, am I missing a framework that would be really beneficial? Thanks in advance and sorry for the relatively broad question... Chris

  • AES decryption in Java - IvParameterSpec to big

    - by user1277269
    Im going to decrypt a plaintext with two keys. As you see in the picture were have one encrypted file wich contains KEY1(128 bytes),KEYIV(128 bytes),key2(128bytes) wich is not used in this case then we have the ciphertext. The error I get here is "Exception in thread "main" java.security.InvalidAlgorithmParameterException: Wrong IV length: must be 16 bytes long. but it is 64 bytes." Picture: http://i264.photobucket.com/albums/ii200/XeniuM05/bg_zps0a523659.png public class AES { public static void main(String[] args) throws Exception { byte[] encKey1 = new byte[128]; byte[] EncIV = new byte[256]; byte[] UnEncIV = new byte[128]; byte[] unCrypKey = new byte[128]; byte[] unCrypText = new byte[1424]; File f = new File("C://ftp//ciphertext.enc"); FileInputStream fis = new FileInputStream(F); byte[] EncText = new byte[(int) f.length()]; fis.read(encKey1); fis.read(EncIV); fis.read(EncText); EncIV = Arrays.copyOfRange(EncIV, 128, 256); EncText = Arrays.copyOfRange(EncText, 384, EncText.length); System.out.println(EncText.length); KeyStore ks = KeyStore.getInstance(KeyStore.getDefaultType()); char[] password = "lab1StorePass".toCharArray(); java.io.FileInputStream fos = new java.io.FileInputStream( "C://ftp//lab1Store"); ks.load(fos, password); char[] passwordkey1 = "lab1KeyPass".toCharArray(); PrivateKey Lab1EncKey = (PrivateKey) ks.getKey("lab1EncKeys", passwordkey1); Cipher rsaDec = Cipher.getInstance("RSA"); // set cipher to RSA decryption rsaDec.init(Cipher.DECRYPT_MODE, Lab1EncKey); // initalize cipher ti lab1key unCrypKey = rsaDec.doFinal(encKey1); // Decryps first key UnEncIV = rsaDec.doFinal(EncIV); //decryps encive byte array to undecrypted bytearray---- OBS!

  • SharedObject (Flex 3.2) behaving unexpectedly when query string present in URL

    - by rhtx
    Summary: The behavior detailed below seems to indicate that if your app at www.someplace.com sets/retrieves data via a SharedObject, there is some sort of .sol collision if the user hits your app at someplace.com, and then later at someplace.com?name=value. Can anyone confirm or refute this? I'm working on a Flex web app that presents the user with a login page. When the user has logged in, he/she is presented with a 'room' which is associated with a 'group'. We store the last-visited room/group combination in a SharedObject - so when a given user logs in, they are taken into the most recent room in which they were active. That works fine, but we also have an auto-login system which involves the user clicking on a link to the app url with a query string attached. There are two types of these links. 1) the query string includes username, groupId, and roomId 2) the query string includes only the username Because we are working fast and have only a few developers, the auto-login system is built on the last-vist system. During the auto-login process, the url is inspected and if groupId and roomId values are found in the query string, the SharedObject is opened and the last-visit group/room id values are overwritten by the param values. That works fine, also, when the app is hit with a query string of the second type (no groupId and roomId params), the app goes to the SharedObject to get the stored room and group id values, as it normally would. And here's the problem: The values it comes back with are whatever the last room/group param values were, not whatever the last last-visit room/group values are. And if the given user has never hit the app with query string that included group and room id values, the app gets null values from the SharedObject. It took some digging around, but what it looks like is happening is that a second set of data is being stored/expected in the SharedObject if a query string is present in the URL. Looking at the .sol file in a text editor I see more untranslated code, and additional group and room values, once I've hit the app with URLs that contain query strings. I'm not finding anything on the web about this, but that may just be due to a lack of necessary search skills. Has anyone else run into anything similar? Or do you know how to address this? I've tried setting Security.exactSettings to false, already - was really hoping that was going to work.
