Since you are a beginner, I'd advice you to take a
look at Marty Hall's website
http://www.coreservlets.com/. You can download the
first edition of his book "core servlets and Java
Server Pages" in pdf format. I like Marty Hall's books too, but I prefer Hans Bergsten's JSP book as a starter.
Try to find something about the MVC or Model View
Controller design pattern. This may seem like
overkill for small web apps, but as soon as you're
trying to add some functionality (as you want to do),
you'll see that you gain time using the MVC.
For this, I strongly recommend the "Apache Tomcat
Bible" from Eaves, Jones and Godfrey.
It explains how to install Java SDK, MySQL, Ant,
Eclipse, Tomcat.Personally, I think all this is beyond the OP. He said he was a beginner. If that means he hasn't even written "Hello, World" or compiled a single Java program, I'd say that all this stuff about Tomcat, Ant, Eclipse, serlvets, and JSPs is well beyond him. I'd discourage anyone from taking on a project like this as their introduction to Java. I'd warn his client against spending their money to buy code from a neophyte. There are plenty of talented people out there who need the work and can do the job without having to climb that learning mountain.
If I've misread the situation, I apologize. No insult intended. Just be realistic in assessing your ability and the difficulty of the project.

  • What is the best editor to use for JSP/Servlet?

    Hello,
    What is the best editor to use for JSP/Servlet database development.
    I'm looking at Dreamweaver,Java Studio Creator.
    I want some thing fairly easy to use that has database helper wizards like dreamweaver.
    Thanks for the help.
    Frank

    Is it better to have a servlet do the database work and call it from JSP?No, it's better to have persistence objects do the database work. Servlets handle HTTP requests, and JSPs are HTML factories that should be pure view.
    But there are lots of ways to do things. You just have to understand the tradeoffs when you decide.
    I do not want to hammer out code, I want to learn the
    best way to do things from experienced developers. Sorry, sounded like you just wanted to churn stuff.
    "best way" can be subjective. In one app, "best" might be "delivered fastest". For another, "best" might be "most secure" or "most easily modified" or "best performing" or whatever. You won't get a "best" answer, only different choices. And they aren't always so easy to explain or execute.
    I'd recommend that you start by reading about layered applications (3-tier architectures) and MVC separation. Once you've Googled enough about that, look into a framework like Struts or Spring or WebWork. That'll help you figure out where to put each responsibility in your app.
    I can use dreamweaver to create web apps, but I hate
    the arrays used to define fields. It also seems not
    to take advantage of connection pooling.Don't know what you're talking about here, Frank. What do fields have to do with connection pooling?

  • What is the plugin used for jsp/servlet development , deployment in eclipse

    what is the plugin used for jsp/servlet development , deployment in eclipse?
    can some body tell me what are the other plugins to be used in enterprise java developement
    is eclipse would be a best choice j2ee application development?
    thanks

    what is the plugin used for jsp/servlet development ,
    deployment in eclipse?There are several J2EE plugins I think. One is Lomboz.
    can some body tell me what are the other plugins to
    be used in enterprise java developementPfft...
    1) Might depend on what you're doing. J2EE is not just JSP, you know?
    2) Why do you ask about Eclipse IDE at Sun's Java Programming forum?
    3) Do you really want me to list the 5000 plug-ins someone might use for J2EE-related development?
    4) Open fucking Google and search yourself
    is eclipse would be a best choice j2ee application
    development?IMO: no. Simply because you have to look for J2EE plugins. I'm too lazy for that. Though it has other benefits that might outweigh the plug-in-searching issue.

  • Problems access to a web application (Web Interface or Web report)

    Hi,
    We found problems with the access to web application. Some users have problems with direct links to the web applications(Web Interface or Web reporting), when they click on the link an error message appears, the message displays the following text:
    "Cannot open file Bex?sap-language=ENbsplanguge=ENcmd=idoc_TE.."
    Clicking in details the message is "No Access to specified file"
    For this users the access to excel reporting is correct, the message appears when they click on the direct web links through the browser or directly in BW system, but if they type the URL they can access. Other users can use the direct web link without problems.
    I highly appreciate any help or idea about how to solve this issue.
    Thanks in advance.

  • How to call jsp /servlets running in different web application in tomcat

    hello all,
    i have 2 web applications(Charts and Reports) in the same tomcat,i want to call jsp/servlets running in the Reports webapp from Charts webapp.how do i achieve this.
    thanx
    ravi

    You can also use getContext(String context) in the ServletContext class to get a request dispatcher.
    Using the above example it would be :
    // in a servlet in the charts webapp
    ServletContext context = getServletContext();
    ServletContext reportsContext = context.getContext("/reports");
    RequestDispatcher dispatcher = reportsContext.getRequestDispatcher("/path")
    dispatcher.forward(request, response);Just note, that depending on your server's configuration getContext(...) might return null.

  • Use jar file for one servlet in one application (not global in classpath)

    I have a servlet application that needs a jar file to load with one particular servlet. If I put the classpath to the jar file in the jvm12.conf, the servlet loads fine. I can't run it like that, however, since I use another jar file by the same name in a different application. I would like to specify it only with the servlet that needs it. According to the online help file, it says more than one jar, zip, or class file can be specified in the servlet classpath, but that doesn't seem to be the case. We're running iPlanet 4.1. I've tried adding the classpath to the jar file after the classpath for the servlet itself (servlet.properties), but it gives the class not found error for that function. Is there a way to do this? Context.properties, maybe? I can't find any instructions on setting that up.

    You might have better luck asking this question on a web server forum. This is an application server forum and most people here are going to more experienced with iAS.

  • Error in accessing pageContext or current session for JSP/servlet in frames

    I am creating a web application on iPlanet application server (ver 6.0 SP4) and display a page
    consists of frames in web browser (IE6). The framset and the content of each frames are
    JSPs or servlets. There where no problem to display each content frames individually at all.
    However, when the overall page (the frame set and the 3 frames) is displayed, the following
    problem occurs.
    Only the outermost frameset and just one or two of the frame contents displayed successfully
    in browser. Others have either 1 of the following errors:
    1. When accessing pageContext object in _jspService routine when displaying the JSP page, Null
    Pointer Exception occurs:
    java.lang.NullPointerException
    Exception Stack Trace:
    java.lang.NullPointerException
    at jsp.APPS.intl.acct_type_option._jspService(acct_type_option.java:653)
    2. When calling the req.getSession method in doGet() method for servlets, the following
    exception occurs:
    Exception in doGet(): This session has already been invalidated
    The occurance of error is random among all the frames. With the frame on top or left size
    having the most chance to be displayed successfully.
    It seems that the Application server cannot entertain 3 or 4 requests simultaneously (which
    happens when displayed a page consists of frames), having some of them throw an exception.
    Are they any tuning or setting for iPlanet server to overcome this problem?

    I'll give you the same advice as I have been given regarding the use of frames.
    Don't use them at all. Use scrollable DIV's instead.
    The use of frames is such that you would have different JSP's who cannot collaborate together since each is in his own frame and does not know about the others.
    In case I'm mistaken, I'd like to hear about it, but the combination of JSP's and frames is an unhappy one.

  • Using a single connection for jsp, servlets and classes

    Hi! I'm building a web site that uses JSP, Servlets and some classes. I use database access in all my pages. I want to open a connection and use it for all the pages while the user is in my site, so I don't need to open a connection with every new jsp or servlet page. My software must be capable of connection with various databases, like SQLServer, Oracle, Informix, etc... so the solution must not be database (or OS or web server) dependant.
    Can you help me with this? Some ideas, links, tips? I'll REALLY appreciate your help.
    Regards,
    Raul Medina

    use an initialiation servlet with pooled connection which can be accessed as sesssion object.

    For broadcasting which is suitable linux cpanel or windows flesk?
    Thanks

    BumpIf nobody cared about this the first time, why do you
    think it needs to be bumped?1. My original post was on Friday, probably not the best time to get a response. So I bumped it up Sunday night to try for a response Monday morning.
    2. Fred visits the forums on Friday, but doesn't have a comment. Bob on the other hand doesn't visit the forum on Friday, but he does on Monday, and he has some advice.
    3. Do you give up the first time?

  • Any learning assignement/project site for jsp/servlet?

    I have been reading 1 month now on servlet and jsp. I would like to read existing project code or do some small assignment/projects. Does anyone know good website that offers that? I am already using javapassion.com. Thanks.

    You mean is there a tutorial specifically dedicated to teaching you how to develop a web application for those tasks? Possibly, but it won't necessarily be easy to find. However, start with the basics.. work through the tutorials you come across. I think you'll find a lot of the concepts in those will give you a much better insight as to how to accomplish different, and possibly more complex tasks.

  • Different Classloader for JSP, Servlets?

    Hi!
              Does the WL5-JSP-servlet use an other classloader then the other
              servlets??
              I've previous posted an article with the subject "JSP - Servlet - Static
              Code in Classes".
              I will try to describe my problem better:
              At server startup I pass information to my startup servlet, for example
              the user and pw for our connection pool. The startup servlet instanciates
              the class Global which creates a db-pool with the user and pw getting
              from
              the startup-servlet.
              startup-servlet {
              public void init(ServletConfig config)
              Global.init("user","pw");
              The class Global looks like this:
              class Global {
              static {
              // register jdbc driver
              // store file informations
              static public init(string, string) {
              // init the connection pool with user and pw
              static public getConnection() {
              // returns connection from pool
              All our other servlets then just use the methode Global.getConnection()
              and other methods from the class Global.
              All servlets works perfect and can access the db-pool.
              When a jsp-file is called which also uses the methode
              Global.getConnection(), a new Instance of the class Global will be made.
              In order to init all values again, I would have to call the
              Global.init(user, pw) methode again.
              So my question is: Why does the jsp file causes a new instance of the
              class Global?
              Does the WL5-JSP-servlet use an other classloader then the other
              servlets??
              

    I am seeing the problem is sp3. I can't use sp4 becuase form based
              authentication, FBA, was broken. I can only hope that FBA will be
              re-fixed in sp5.

  • Good IDE for JSP/Servlets Development

    Guys, I was looking for a good IDE for JSP/Sevlets development. I for myself wouldn't need or atleast wouldn't want to have one, but for our production they say they need one. So please can u guys advise one. I have downloaded and tried JDeveloper but it just hangs, dont know but looks like its too memory intensive. Any suggestions??? Thanks in advance

    IBM's Websphere Studio Application Developer (WSAD) is a good one. It can also connect to any CVS servers, which allows you to control the versions. Hope this may help you...

  • Please sugges the link helpful for writing efficient sql queries

    Please suggest any good resource that is weblink which can help me in optimizing sql queries. especially while writing select statements improve the execution time of the sql query.
    Thanx in advance
    prasanth

    in general I found books from O'Reilly very helpful (not only for Oracle, but for Unix too).
    Moreover there is pretty good Oracle Documentation available.
    After all, it's not only about writing good queries, but also about setting up data-models, indexes, primary keys, etc.
    Look for a real slow computer, take a lot of data, then try writing your speedy queries. This is the school of hard knocks, on the long run it's the best training.
