ATM model with Servlet and Cookies(class assignent)

i am struggling starting a class assignment. I am suppose to use and access database, a servlet and cookies. If i understand correctly the servlet will have the buttons and GUI? What would i use the cookies for? or how would i use cookies in such an application? Please help.
ty,
max

A servlet will typically generate HTML content. The generated HTML will contain tags which will be rendered into buttons and the like. Cookies are used for persisting state about a particular web browser across several sessions. For example, if a user enters their name in your system you could set a cookie (which would be stored on the client's machine). Then, when they return to the site you can re-access the cookie which was originally set.
Good luck,

  • J2EE Servlets and Cookies

    I'm having trouble with session management (Apache 2 + WAS keep killing my sessions, likely due to my lack of understanding of how to configure the latter). I don't have time to resolve this.
    What I'm going to do instead is use the old standby, cookies, to manage sessions. The problem is, I don't know how to do that either. Could someone point me to a good online tutorial on the subject? I've used a few google searches without any luck (course ads only).
    Lest I sound like a complete incompetent, I should mention that I am skilled with J2SE (been using it since before it was called that) and have a basic understanding of J2EE.
    thanks,
    Andrew

    Whereas I haven't used cookies myself, I believe the mechanism is pretty streight forward...
    Here is the API for J2EE: http://java.sun.com/j2ee/1.4/docs/api/
    There are three places you will need to look.
    1) The javax.servlet.http.Cookie class.
    If you want to create a cookie, you will have to make an instance of this class, then use the appropriate set methods. When reading an already stored cookie, use the get methods...
    2) The javax.servlet.http.HttpServletRequest interface provides the means of retrieving cookies from the user's machine via the Cookie[] getCookies() method.
    3) The javax.servlet.http.HttpServletResponse interface provides the means of adding a cookie to the user's machine via the void addCookie(Cookie c) method.

  • 3 tiers model with Java and Oracle.

    Hi everybody. I have a problem with my work. I want to design a simple program follow 3 tiers model with Java and database is Oracle. But I do not know how I can design them. Please help me. It will better if you give some source code for each layer.
    Thanks in advance.
    Ky Thanh.

    I'd suggest searching the net for tutorials. Pick out the things you don't know about and need to know (SQL? JDBC? Java? software design in general?) and google: tier architecture, sql tutorial, etc. Sun's Java & JDBC tutorials are at http://java.sun.com/learning/tutorial/index.html
    Source for each tier? Read the JDBC tutorial and you can write the database tier source yourself. Learn Swing/Servlets/whatever you use for the user interface and you can write the top tier. The middle tier is your business logic, which is dependent on your area of business, and you'll need to know about the business and just general programming. Then if the tiers need to be distributed (hopefully not), you'll need to learn EJB or something.
    I hope you haven't been given a task there you aren't ready to take on... Learning to swim by jumping into the river is a great way to learn in a school assignment, but you mention work, and learning that way at work sounds a bit risky to me.

  • Creating model with Control and Design LV2009

    Hello,
    I'm trying to make a PI control model with Control and Design in labview 2009. I'm tyring to create the following transferfunction:
    D(z)=Kp+((Kp*Ki)/(1-z^-1))
    But labview adds by itself an extra z^-1 in the Numerator
    See the attachment what I have tried. I first want to create 1+(1/(1-z^-1)). What I'm I doing wrong ?

    Jeroen,
    The two expressions "1+(1/(1-z^-1))" and "(2-z^-1)/(1-z^-1)" are equivalent to one another.  They just have the terms rearranged.  Since LabVIEW expresses a transfer function as a numerator and denominator, it is drawing the function as "(2-z^-1)/(1-z^-1)".  You aren't doing anything wrong.

    Hi
    I guess u r running apache-jserv as servlet engine for your jsp and servlets. If its so, jsp files can be run without any additonal configuration by putting the jsp file under document root or any subdirectory and for running servlets u have to add classpath entries for your servlet in jserv.properties file.
    To make sure that your servlet engine is working, try
    http://servername:port/servlet/IsItWorking, if u get success msg that means servlet engine is working fine.
    Hope this will help

  • Apache with Tomcat and dispatcher class.

    I have a MVC design set up with a controller and dispatcher class. I am trynig to forward the results to a specific JSP. If I run the design completely within Tomcat, then everything works great. I have a tomcat site set up called /jsp. My servlet is within the jsp site. So if I do http://localhost:8080/jsp/mypage.jsp it will bring up the page fine. I then submit to and action of /myservlet?action=test. The servlet/dispatcher classes process and forward the request to "/jsp/mypage_result.jsp". All is fine and dandy.
    However, when I try to run this through Apache first let the MOD_JK2 send the JSP/servlet requests to Tomcat the dispatcher doesn't work. I alway get the ERROR 404 page within tomcat (see note 1 below). Even if I use a "./mypage_result.jsp", because the pages are in the same directory, I still the get the error. Can anyone help?
    What I think is happening is that when I make the inital request of http://localhost/jsp/mypage.jsp the request gets sent to Tomcat from Apache. Tomcat processes the jsp page and displays the result to the client. The user submits the data to the servlet (through Apache which pushes it to Tomcat). The servlet/dispatcher code runs and then gets ready to forward the request on. Where I get confused or I am completely guessing is that when the forward method gets called. Does it forward the request on as a HTTP request or as a request within Tomcat? I would guess it is an http request and the request comes in through Apache which (depending on the worker2.properties file) will or will not forward the request to Tomcat. This is where the problem happens. On this forward in the dispatcher class.
    Please help.
    NOTE 1:
    HTTP Status 404 - /mypage_result.jsp
    type Status report
    message /mypage_result.jsp
    description The requested resource (/mypage_result.jsp) is not available.
    Apache Tomcat/4.1.24

    After reading the documentation for the getRequestDispatcher method it seems that the file you are forwarding to must be in the same context. Well if it is in the same context within Tomcat, does it mean it is the same when I am trying to use Apache?
    Anyone out there go this to work?
    Thank you in advance for reading my post.

  • Working with traits and policy classes

    I have not been able to see if anyone has raised this before from my searches of the forums but this may just be bad searching !
    I am trying to investigate how much of the traits / policies idioms of working in C++ generic programming are applicable to Java. The following trio of classes are a very striped down version of one problem I am having. It relates to the use of static methods, inheritance and generic classes.
    First a couple of classes with static methods related by inheritance.
    public class X {
      public static int get() {
        System.err.println("X.get.") ;
        return 1 ;
    public class Y extends X {
      public static int get() {
        System.err.println("Y.get.") ;
        return X.get() + 1 ;
    }Now a class that uses the types as type parameters and tries to call the static method:
    public class TypeParameterLookupSolved<A extends X> {
      private void doit() {
        System.out.println(A.get()) ;
      public static void main(final String[] args) {
        TypeParameterLookupSolved<Y> tpli = new TypeParameterLookupSolved<Y> () ;
        tpli.doit() ;
    }The output from running this is:
    X.get.
    1
    So the question is why does the call of A.get() always bind to X.get() when na�vely you would expect Y.get() to be called.
    If Java will only ever call X.get() in this instance then the policy class idiom will not work properly . Of course it may be that there is another way of doing this that I have missed.
    Thanks.

    Thanks for the correction.
    I never can get the hang of up and down in type hierarchies -- functional programming people talk a lot about top and bottom in type hierarchies and I never remember which is which. One of these days I will find a mechanism for putting the knowledge into long-term memory :-)
    Having had the epiphany of "least upper bounds", it is now trivially easy to do Java-style generic programming (which is good :-) even though it is totally different to everyone else (C++, Python, Groovy, Ruby, Nice, CL, OCAML, Haskell, . . .-- which is not so good). I am increasingly of the view that using the term Generics has been a labelling error and an unfortunate disservice to Java as it can set up a mind-set about parameterized types and "generic programming" that is fundamentally wrong. I can feel a series of short articles coming on as well as sorting out my ADS library!

  • Sharing config with Servlet and Web Services

    Hi,
    I am building a Servlet wrapper and a jaxrpc wrapper for my application, so that my client can invoke either servlet or web services to access my application.
    my main application library is at WEB-INF/lib and both the servlet and
    webservices are in WEB-INF/classes.
    I am trying to make them sharing the same configuration file web.xml so that common attributes such as log file location can be read. I know Servlet can read the context and parameters but how to make my web services app to read it, since the web services are not servlet itself but it is invoked by the JAXRPC servlet????
    Thanks

  • AppMod pooling with Servlets and JSPs

    Issue:
    I have a servlet that I need to do some work on a BC4J View Object (myVO), like set the where clause, execute, etc. I want to perform these actions in the servlet, and then forward on to a .jsp page (mypage.jsp). Then I want to use the BC4J Data Tag library to present the data. Normally, the AppMod tag would be used to get ahold of an AppMod, but in my case, I want to use the specific AppMod that I prepared inside the servlet that forwarded to mypage.jsp.
    I have looked through the BC4J Data Tag library and it appears that the data tags are getting the AppMod from the page context. I looked at the AppMod tag and I couldn't see exactly where it was sticking the AppMod into the page context, but when I looked at the DataSource tag, it was retrieving the AppMod from the page context. Therefore, I am assuming the AppMod tag is sticking it into the page context.
    What I would like to be able to do is perform some work on the AppMod in my servlet, then forward to a .jsp. Once in the .jsp, I would like to reference the AppMod without having to use the AppMod tag, but reference the AppMod directly from the DataSource tag. This would allow me to completely manage the AppMod interaction in my servlet, thus centralizing that logic and avoiding multiple check-ins/check-outs of the AppMod. I could also avoid using stateful management of the AppMod.
    Any insights would be much appreciated!
    Thx,
    Eric

  • I bought a used macbook air (newest model) with lion and when I try and install iPhoto it says "These apps cannot be accepted by your Apple ID. These apps were already assigned to another Apple ID, and they will be available in that Apple ID's Purchases "

    I am a new mac user so there is a lot that I don't yet know or understand.  The previous owner did a clean re-install of lion and my air is covered under warranty till August.  We called apple when I bought it to make sure it wasn't stolen and registered it to me. I am just trying to be able to transfer my pictures from my iphone to my air.  I also want to set up icloud which looks like it requires iphoto. Also, what are the other iLife apps?  I have a feeling I will encounter the same issues with those. Thanks for your help.

    If new versions of iPhoto and the other iLife applications (iMovie and GarageBand) were purchased by the previous owner from the Mac App Store, then they will be locked to the previous owner's Apple ID and cannot be transferred to you. You will have to re-purchase them under your own Apple ID.
    If this is an older MBA that came with Snow Leopard or an earlier version of Mac OS X, though, the system would have come with an installation disk that included the iLife applications, a disk which the seller should have provided to you. Those iLife applications would be older versions, of course, and may or may not work in Lion depending on how old they are.
