  • html select option tag closes itself due to a "/" character in the dynamic value (JSP, JSTL)

    - by saky
    <select id="ordersSelect" class="drop-down" onchange="somemethod()"> <c:forEach items="${orders}" var="order" varStatus="orderStatus"> <option value="${order.id}"> ${order.publicId} </option> </c:forEach> </select> I have the above peice of code in a JSP page, that receives a list of Orders and each order has some information, the particular information that I want to display in a SELECT field is the publicId. The problem is that, on display there is only one OPTION in the SELECT and the rest of the order's publicId s are displayed as normal text below the SELECT box and not an OPTION to select. I found out that the publicId actually contains a String like A10/0001/0 and that is the character "/" is most probably causing the problem. Any solutions/suggestion/ideas?

  • Does this schema sound better suited for a document-oriented data store or relational?

    - by Blaine LaFreniere
    Disclaimer: let me know if this question is better suited for serverfault.com I want to store information on music, specifically: genres artists albums songs This information will be used in a web application, and I want people to be able to see all of the songs associated to an album, and albums associated to an artist, and artists associated to a genre. I'm currently using MySQL, but before I make a decision to switch I want to know: How easy is scaling horizontally? Is it easier to manage than an SQL based solution? Would the above data I want to store be too hard to do schema-free? When I think association, I immediately think RDBMSs; can data be stored in something like CouchDB but still have some kind of association as stated above?

  • Extending the RoleProvider GetRolesForUser()

    - by Farinha
    The GetRolesForUser() method in the RoleProvider takes the user login name and returns the list of roles for that user. But in my application this is not enough, I need a few more pieces of information to be able to get the user's roles. How can I get this extra information into the method? I have it in the Session, but I found out that Session is not available in the RoleProvider. What I had in mind was putting this extra info in some class that extends MembershipUser, assuming I can get to it inside the RoleProvider. But I don't know how to create the CustomMembershipUser and make it part of the MembershipProvider. Is this even possible? The easy way out would be using cookies, but I'm trying to keep away from it.

  • MVC Pattern Clarification

    - by Amutha
    Just I started learning MVC pattern,ofcourse i am learning it from Microsoft's website.Just i want to gather quiz information from the experts. My understanding is (correct me then and there) 1 ) MVC does not support server side events ,but supports client side events.if it supports client side events,i need html page with jQuery/Javascript (view),but most of the example i absorbed is to display the information(model) in view ,i did not see any client side event handling happens in view. 2) Except ViewState and controlState,MVC supports Sessions,Application State management,Cache management. 3) When request goes to MVC engine ,the routing module routes the request that is picked up by the controller.The controller in executes the appropriate action and return the appropriate view.

  • Dealing with HTTP Status Codes in PHPUnit_Extensions_Selenium2TestCase

    - by frosty
    I have a series of tests that I'm running for an Open Source Project, I'd like to get the status code of the curl request that is made to determine the difference of a code change breaking functionality vs a code change breaking the site completely. class ExampleTest extends PHPUnit_Extensions_Selenium2TestCase { public function setUp() { $this->setBrowser('firefox'); $this->setBrowserUrl('http://localhost'); } public function testForError() { $this->url('/'); $this->assertNotEmpty($this->title()); } } That's an example of how I'm going about it now, but I'd like to have some concrete information. Short of getting the information from the CURL request, I'm not really sure how to go about this...

  • Network communication for a turn based board game

    - by randooom
    Hi all, my first question here, so please don't be to harsh if something went wrong :) I'm currently a CS student (from Germany, if this info is of any use ;) ) and we got a, free selectable, programming assignment, which we have to write in a C++/CLI Windows Forms Application. My team, two others and me, decided to go for a network-compatible port of the board game Risk. We divided the work in 3 Parts, namely UI, game logic and network. Now we're on the part where we have to get everything working together and the big question mark is, how to get the clients synchronized with each other? Our approach so far is, that each client has all information necessary to calculate and/or execute all possible actions. Actually the clients have all information available at all, aside from the game-initializing phase (add players, select map, etc.), which needs one "super-client" with some extra stuff to control things. This is the standard scenario of our approach: player performs action, the action is valid and got executed on the players client action is sent over the network action is executed on the other clients The design (i.e. no or code so far) we came up with so far, is something like the following pseudo sequence diagram. Gui, Controller and Network implement all possible actions (i.e. all actions which change data) as methods from an interface. So each part can implement the method in a way to get their job done. Example with Action(): On the player side's Client: Player-->Gui.Action() Gui-->Controller.Action() Controller-->Logic.Action (Logic.Action() == NoError)? Controller-->Network.Action() Network-->Parser.ParseAction() Network.Send(msg) On all other clients: Network.Recv(msg) Network-->Parser.Deparse(msg) Parser-->Logic.Action() Logic-->Gui.Action() The questions: Is this a viable approach to our task? Any better/easier way to this? Recommendations, critique? Our knowledge (so you can better target your answer): We are on the beginner side, in regards to programming on a somewhat larger projects with a small team. All of us have some general programming experience and basic understanding of the .Net Libraries and Windows Forms. If you need any further information, please feel free to ask.

  • Discovering Assets on Multiple Subnets

    - by Owen Allen
    I saw this question recently, about making discovery work: "I am attempting to discover a group of ILOMs which seem to be on a different subnet than their hosts. When I try to discover the ILOMs, Ops Center can't find them. Is it a requirement that the ILOM and its host should be on the same subnet?" The short answer is no, related assets don't have to be on the same subnet for you to discover them. The correlation between related assets doesn't depend on them being on the same subnet. What's likely going on, if you're running into similar issues, is that the subnet where you're trying to discover systems needs to be associated with a Proxy Controller that can reach it. You can go here to see how to associate a network with a Proxy Controller. Once the network is associated with a Proxy Controller, you should be able to discover and manage assets on it.

  • How do I make "simple" throughput servlet-filter?

    - by Tommy
    I'm looking to create a filter that can give me two things: number of request pr minute, and average responsetime pr minute. I already got the individual readings, I'm just not sure how to add them up. My filter captures every request, and it records the time each request takes: public void doFilter(ServletRequest request, ...() { long start = System.currentTimeMillis(); chain.doFilter(request, response); long stop = System.currentTimeMillis(); String time = Util.getTimeDifferenceInSec(start, stop); } This information will be used to create some pretty Google Chart charts. I don't want to store the data in any database. Just a way to get current numbers out when requested As this is a high volume application; low overhead is essential. I'm assuming my applicationserver doesn't provide this information.

  • Best Practices of fault toleration and reliability for scheduled tasks or services

    - by user177883
    I have been working on many applications which run as windows service or scheduled tasks. Now, i want to make sure that these applications will be fault tolerant and reliable. For example; i have a service that runs every hour. if the service crashes while its operating or running, i d like the application to run again for the same period, to avoid data loss. moreover, i d like the program to report the error with details. My goal is to avoid data loss and not falling behind for running the program. I have built a class library that a user can import into a project. Library is supposed to keep information of running instance of the program, ie. program reads and writes information of running interval, running status etc. This data is stored in a database. I was curious, if there are some best practices to make the scheduled tasks/ windows services fault tolerant and reliable.

  • Using Java to retrieve the CPU Usage for Window's Processes

    - by stjowa
    Hello all, I am looking for a Java solution to finding the CPU usage for a running process in Windows. After looking around the web, there seems to be little information on a solution in Java. Keep in mind, I am not looking to find the CPU usage for the JVM, but any process running in Windows at the time. I am able to retrieve the memory usage in Java by using the exec("tasklist.exe ... ") to retrieve and parse process information. Although there is an aggregate CPU cycle timer for each process, I do not see a CPU usage column. Any help would be greatly appreciated. Also, if possible, I would like to stay away from C libraries; however, if there is no other alternative, a solution by that means would be appropriate. Thanks a lot, Steve

    - by Dave
    Hi, i'm buidling a very simple email based website that users can, when registering list out all the stocktickers they're intersted in following. The program then on a daily basis goes and fetches that information and sends it out to every user. i have the portion which fetchs the information from the stock websites, but i'm looking for an "infrastructure" that allows: (a) a user to send an email to [email protected] with the subject "Subscribe" and with the body containing stockticker values, (b) user to send email to service@... with subject "unsubscribe" and body containing similar values. Looking for code in php please. Any insights?

  • How do i make/setup a mailing list?

    - by acidzombie24
    I know i could program it myself but maybe there is a simple (thats the keyword) package. I like to add a box, snippet, form or page to my site for users to input their email address. Then i'd like it to automatically send email saying you have successfully subscribe. I'd want an unsubscribe link and i would be using smtp on google apps. I would like to send email with html so i can have a simple sentence with a complex link such as this I dont know if i'll get marked as spam if i try to send everyone an email at once? so i'd like the software to manage it. Also i'd like to get the emails in a simple format like csv. Is there a simple app that does this? if not i can write a simple form which does a simple insert (or delete when unsubscribing) and write a 200-300line app to send my emails out for me.

  • Interviewing a DBA

    - by kev
    Our Company is in the Process of recuiting a DBA. I have built a group test of questions from basic questions such as Pk and Fk constraints, simple querries(fizzbuzz style) to more advanced things such as indexes, Collation, isolation levels and how to trace deadlocks. However, that is the limit of my knowledge. So my question to all the DBA's is what is the base level knowledge that all DBA's should have? We are really looking for someone that will be able to manage our replication, analyzing some of our slower running queries(that the devs can go to for help) and someone that can trace some of the deadlock issues that we are having. Any help would be most appreciated!

  • Ways to polling server status

    - by Yijinsei
    Hi guys, I am try to create a JSP page that will show all the status in a group of local servers. Currently I create a schedule class that will constantly poll to check the status of the server with 30 second interval, with 5 second delay to wait for each server reply, and provide the JSP page with the information. However I find this way to be not accurate as it will take some time before the information of the schedule class to be updated. Do you guys have a better way to check the status of several server within a local network?

  • Customizing Google Sites look and feel

    - by David Parunakian
    I find the site layout and theming capabilities in Google Sites (found in the Manage Site screen) very limited; for instance, I do not seem to be able to place the horizontal navigation buttons directly to the right of the logo and to customize their style, as well as to use the standard trick of making a horizontally stretchable background image of a box with rounded corners by splitting it into three parts and replicating the middle one, etc. Am I missing something? Are there any advanced settings available? Thanks.

  • Salaries in reverse engineering fields [closed]

    - by John
    I bumped into an old friend at a conference and he told me he was now a consultant doing reverse engineering. I don't have much knowledge of this particular area, but this person (that I can't manage to get in touch with now) just casually mentioned that he was earning big bucks. I was hoping someone at SO may know of the salary range that a skilled and experienced employee/freelancer may earn in this area? I can't find much information on the web - small area maybe? I dunno. Any help would be appreciated.

  • What are some tips for troubleshooting builds of complicated software?

    - by Goose Bumper
    Sometimes I want to build Python or GCC from scratch just for fun, but I can't parse the errors I get, or don't understand statements like "libtool link error # XYZ". What are some tricks that unix/systems gurus use to compile software of this size from scratch? Of course I already do things like read config.log (if there is one), google around, and post in newsgroups. I'm looking for things that either make the process go smoother or get me more information about the error to help me understand and fix it. It's a little tough to get this information sometimes, because some compile bugs can be quite obscure. What can I do at that point?

  • Thoughts on Development using Virtual Machines

    - by J_A_X
    I'll be working as a development lead for a startup and I've suggested that we use VMs for development. I'm not talking about each developer having a desktop with VMs for testing/development, I mean having a server rack where all VMs are managed and have the developers work from a microPC (ChromeOS anyone?) locally, or even remotely from their home computer. To me, the benefits are the fact that it's extremely scalable, cheaper in the long run, easier to manage and that we utilize the hardware its maximum potential. As for cons, I can't think of any particular showstoppers other than we'll need someone to setup/maintain said setup. I was hoping that some of you might of had a similar setup at your place of employment and be able to weight in with your opinions. Thanks.

  • Extract item in a list if Contains returns true

    - by Matt
    I have two lists A and B, at the beginning of my program, they are both filled with information from a database (List A = List B). My program runs, List A is used and modified, List B is left alone. After a while I reload List B with new information from the database, and then do a check with that against List A. foreach (CPlayer player in ListA) if (ListB.Contains(player)) ----- Firstly, the object player is created from a class, its main identifier is player.Name. If the Name is the same, but the other variables are different, would the .Contains still return true? Class CPlayer( public CPlayer (string name) _Name = name At the ---- I need to use the item from ListB that causes the .Contains to return true, how do I do that?

  • ASP.NET State Error

    - by Sayem Ahmed
    I am have an asp.net page, where a list of products is shown in a drop down. When a user selects an item, corresponding price, available quantity etc. are shown in the corresponding text boxes. I have used ajax update panel to retrieve these information. This approach seems to work nicely. But sometimes when a product is selected, it takes too long for the price, quantities to change, and sometimes they don't even change. Then I used firebug to see what happened to the ajax request, and I found out that the response that is coming from the server is something like this - 70|error|500|The state information is invalid for this page and might be corrupted.| I have absolutely no idea what is wrong here.............
