Benefits of MVC approach with JSP ?

Just read an excellent (but dated) article of using the Model-View-Controller patteren with a shopping cart application
http://www.javaworld.com/javaworld/jw-12-1999/jw-12-ssj-jspmvc.html
just wondering if this is still a common and preferable approach ?

From my experience, both Models defined in that article are still both very common ways to approach an application. You may have noticed that most of the problems with the Model 1 approach, as listed in that article, deal more with project management issues rather than design issues. Using solely the JSP is no less effective than using the Servlet as a controller, except that with the Servlet you do see some obvious separation of roles. I generally prefer the first approach, but most of my projects use extremely small teams (if not just myself) of developers and as such are easy to manage.

Best approach with jsp

hi,
i have a scenario that's sending data from jsp.
i have two options, soap and client java proxy.
what is best approach for this?, becasue jsp is calling java which contains coding to call webservice, so this is similar with client java proxy.
if you are me, what is the best? soap or cleint java proxy? eventually, soap also proxy.
please guide me what is big point? i do not want to get you with basically different point that i know that client java proxy is ejb. soap is wsdl...
thanks & regards;

Hi,
As you already have a J2EE application ( a JSP ), i would suggest that you use Java Proxies for the same to integrate with XI. Proxies allow you to have a better perfromance and so, I would suggest to go with Java Proxies.
For Java proxies this how to guide would help,

Authentification and Security in WebApp with JSP

Hello to all.
I'm developing a Web Applications with JSP's. To use the application a user must first Login.
To restrict access via URL typing I have included in every JSP page a user_logged_in_check page that verifies that the user is logged in, and if not redirects to the Login page.
The problem is that I must not forget to include that page in all my JSPs, and if the name of the page changes, it must be changed everywhere (though a search/replace might do the job just fine).
I used this approach because is not server dependent (such as the Tomcat Realms example I have seen on this forum).
Is there a better strategy?
Is there a way to enforce security check and not rely on my attention ;)?
Is there a pattern that solves the problem?
Any help would be greatly appreciated.

The first and biggest disadvantage is the repetitive coding - what happens if you realise that you need to change something - you will need to modify each of your JSP files. The chances of someone forgetting to add it in are a security risk.
Secondly, using the web server's mechanism, in most cases, would mean that you are using a proven and much more stable security mechanism then you can whip up.
For example, in Weblogic, you can configure a JAAS provider -- that means you are not limited to using uname/password. Your customer may have an enterprise wide single sign on policy that is supported by the JAAS provider and you can use it straight away - by just making a declarative change in the web*.xml files.
If you must, use the Filter class (its a Servlet class, I checked after I had posted) as described in the Intercepting Filter pattern - at least thats a standard approach and will cut down on you having to rely on adding a snip of code to each of your JSPs.

SQL query with JSP and WML-parameters

Hey,
Could you help me?
I'm trying to do the following. WML deck card 1 send parameter to same WML deck's card help. I try to read the parameter with JSP in card help by putting the parameter to SQL query, but it doesn't work. I can read the parameter with WML in card help. I can also print the value of the parameter with JSP if I generate WML with JSP.
/*parameter sending from card 1 to card help*/
out.println("<go href='#helpcard'>");
out.println("<setvar name='valittukurssi' value='$(valittukurssi)'/>");
/*parameter read with WML in card help */
<p>Valitse kurssi.
$valittukurssi</p>
/'parameter read with JSP by generating WML with JSP*/
out.println("<p>$valittukurssi</p>");
/* SQL query with JSP */
ResultSet uudettulokset = uusilause.executeQuery("select * from kurssi where lyhenne='$valittukurssi'");
Thanks,
Rampe

You're problem is easy to fix. You're confusing WML variables with JSP variables. See below:
>
/*parameter sending from card 1 to card help*/
out.println("<go href='#helpcard'>");
out.println("<setvar name='valittukurssi'
value='$(valittukurssi)'/>");
Above you set a var that will work on the phone, not in JSP.
/*parameter read with WML in card help */
<p>Valitse kurssi.
$valittukurssi</p>
Yes the above does display the parameter, because it is a client side WML var, but you cannot use this variable in the JSP code (that's why your SWL fails).
/'parameter read with JSP by generating WML with
JSP*/
out.println("<p>$valittukurssi</p>");Here's you're problem, the above line is EXACTLY the same as the one before it. When the container parses through this JSP code it translates the above line to:
<p>$valittukurssi</p> on the WML page and the CLIENT uses it's local variable to display it.
What you need and want is to have a variable that can be used in JSP code and output to your WML page. Here's how it's done:
out.println("<go href='#helpcard'>");
String some_name = "valittukurssi";
out.println("<setvar name='"+some_name+"'
value='$("+some_name+")'/>");
//note that you may have to escape the ( and ) with a \
//so we displayed the variable above into the WML page, now we can use it in the SQL query:
/* SQL query with JSP */
ResultSet uudettulokset =
uusilause.executeQuery("select * from kurssi where
lyhenne='"+some_name+"'");//the end of the command is: " ' " ) ;

Create a new directory in server with JSP

Hi,
How can I create a directory in server with JSP.
File dir = new File("a");
dir.mkdir();
does not work. what do I do?
best regards,

Hi
Check the following things.
1. What is the path where you are creating the directory.
2. Do you permissions to create file in that directory.
3. do a delete on that filename if that exists just to be sure. isdeleted = filedir.delete(). Check the boolean flag isdeleted too.
Thanx and Regards

Running other server-side applications with JSP

Hi,
I'd like to know, if is possible run with JSP (Servlet, or JavaBean) other application, which support COM. I used something like this in JavaScript:
application=new ActiveXObject("excel.application");
and I had all possibilities of its API. I'd like to use excel as data source for user-friendly data input.
Thanks for all suggestions

Hi,
I don't realy understand your question.
If your javascript work using activeX, this code is executed on the client side (like the excel application and the excel file).
You can, with a JSP, generate the html page that contain the script.
Where is the problem ?

Can anyone solve this simple MVC problem with ArrayCollection

I have very simple application trying to understand how to apply MVC without any framework. There are quite a few exemples on the net but most do not deal with complex data.
here is my application with 4 files: MVCtest.mxml, MyController.as, MyModel.as and MyComponent.as
first the Model MyModel.as
package model
import flash.events.Event;
import flash.events.EventDispatcher;
import flash.events.IEventDispatcher;
import mx.collections.ArrayCollection;
[Event(name="ArrayColChanged", type="flash.events.Event")]
[Bindable]
public class MyModel extends EventDispatcher
private static var instance:MyModel;
public static const ARRAYCOL_CHANGED:String = "ArrayColChanged";
private var _myArrayCol:ArrayCollection;
public function MyModel(target:IEventDispatcher=null)
   super(target);
   instance = this;
public static function getInstance():MyModel
   if(instance == null)
    instance = new MyModel();
   return instance;
public function get myArrayCol():ArrayCollection
   return _myArrayCol;
public function set myArrayCol(value:ArrayCollection):void
   _myArrayCol = new ArrayCollection(value.source);
   dispatchEvent(new Event(ARRAYCOL_CHANGED));
then the controller: MyController.as
package controller
import components.MyComponent;
import flash.events.Event;
import flash.events.EventDispatcher;
import flash.events.IEventDispatcher;
import model.MyModel;
import mx.collections.ArrayCollection;
import mx.controls.Alert;
import mx.rpc.events.FaultEvent;
import mx.rpc.events.ResultEvent;
import mx.rpc.remoting.RemoteObject;
public class MyController extends EventDispatcher
[Bindable]
public var view:MVCtest;
[Bindable]
public var componentView:MyComponent;
private var _model:MyModel = MyModel.getInstance();
public function MyController(target:IEventDispatcher=null)
   super(target);
   _model.addEventListener("ArrayColChanged", onArrayColChange);
public function initialise(event:Event):void
   getData();
public function getData():void
   var dataRO:RemoteObject = new RemoteObject;
   dataRO.endpoint = "gateway.php";
   dataRO.source = "MytestdbService";
   dataRO.destination = "MytestdbService";
   dataRO.addEventListener(ResultEvent.RESULT, dataROResultHandler);
   dataRO.addEventListener(FaultEvent.FAULT, dataROFaultHandler);
   dataRO.getAllMytestdb();
public function dataROResultHandler(event:ResultEvent):void
   _model.myArrayCol = new ArrayCollection((event.result).source);
public function dataROFaultHandler(event:FaultEvent):void
   Alert.show(event.fault.toString());
public function onArrayColChange(event:Event):void
   componentView.myDataGrid.dataProvider = _model.myArrayCol;

Here is the code to generate the database:
CREATE DATABASE mytest;
CREATE TABLE myTestDB
      myid INT UNSIGNED NOT NULL AUTO_INCREMENT,
      mystring CHAR(15) NOT NULL,
      myinteger INT NOT NULL,
      myreal DECIMAL(6,2) NOT NULL,
      mydate DATE NOT NULL,
      PRIMARY KEY(myid)
) ENGINE = InnoDB;
INSERT INTO myTestDB (mystring, myinteger, myreal, mydate) VALUES ('Test', 123, 45.67, '2012-01-01'), ('Practice', 890, 12.34, '2012-02-01'), ('Assay', 567, 78.90, '2011-10-01'), ('Trial', 111, 22.22, '2009-09-09'), ('Experiment', 333, 44.44, '1999-04-15'), ('Challenge', 555, 66.66, '2012-12-21');
And finally here is the PHP script.
<?php
class myVOorDTO
var $_explicitType = "valueObjects.myVOorDTO";
public $myid;
public $mystring;
public $myinteger;
public $myreal;
public $mydate;
public function __construct()
    $this->myid = 0;
    $this->mystring = "";
    $this->myinteger = 0;
    $this->myreal = 0.0;
    $this->mydate = date("c");
class MytestdbService
var $username = "yourusername";
var $password = "yourpassword";
var $server = "yourserver";
var $port = "yourport";
var $databasename = "mytest";
var $tablename = "mytestdb";
var $connection;
public function __construct()
    $this->connection = mysqli_connect(
    $this->server, $this->username, $this->password, $this->databasename, $this->port);
* Returns all the rows from the table.
* @return myVOorDTO
public function getAllMytestdb()
    $query = "SELECT * from $this->tablename";
    $result = mysqli_query($this->connection, $query);
    $results = array();
    while ($obj = mysqli_fetch_assoc($result))
      $row = new myVOorDTO();
      $row->myid = $obj['myid'] + 0;
      $row->mystring = $obj['mystring'];
      $row->myinteger = $obj['myinteger'] + 0;
      $row->myreal = $obj['myreal'] + 0.0;
      $row->mydate = new Datetime($obj['mydate']);
      array_push($results, $row);
    return $results;
?>
My understanding as to what is going on is: (1) on creation complete the application launch the initialise() function of the controller (2) this function starts the remoteObject which get the data (3) once the results arrive the resultHandler store the data into the ArrayCollection of the model ***this does not work*** (4) even if part 3 did not work, the setter of the ArrayCollection in the model send an event that it has been changed (5) the controller receive this event and assigns the ArrayCollection of the model as the dataprovider for the datagrid in the compoent.
Of course, since the ArrayCollection is null, the application gives an error as the dataProvider for the datagrid is null.
What is missing in this application to make it work properly? I believe this is an example that could help a lot of people.
Even if I change the setter in the model to _myArrayCol = ObjectUtil.copy(value) as ArrayCollection; it still does not work.
Also, it seems that the remoteObject does not return a typed object (i.e. myVOorDTO) but rather generic objects. I am usually able to make this works but in this particular application I have not managed to do it. Again what's missing?
Thanks for any help with this!

How can I create a Login-page with jsp???

Hello,
I have to create a page with JSP code on the Netweaver Developer Studio.
But I do not know how I do it.
Can anyone tell me what to write in the portalapp.xml?
An example would be very helpful.
Thank you
Greetings

As you can see in the example:
The portalapp.xml file (deployment descriptor) provides configuration information for your application, and defines the components and services in your application. For each component and service, you specify the implementing Java class and configuration information.
For more information on the format of the portalapp.xml, see Deployment Descriptor (portalapp.xml).
<application>
    <application-config>
        <property name="SharingReference" value="com.sap.portal.navigation.service, com.sap.portal.navigation.api_mimeservice, com.sap.portal.navigation.helperservice"/>
        <property name="Vendor" value="MY_COMPANY"/>
        <property name="SecurityArea" value="PERMISSION"/>
    </application-config>
    <components>
        <component name="SimpleNavigationExample">
            <component-config>
                <property name="ClassName" value="MY_CLASS"/>
                <property name="SecurityZone" value="no_safety"/>
            </component-config>
            <component-profile/>
        </component>
    </components>
    <services/>
</application>
You can only update in this example, your class name and other details:
<property name="Vendor" value="sap.com"/>
<property name="SecurityArea" value="MyCompany"/>
<property name="ClassName" value="LOGINCLASS"/>
<property name="SecurityZone" value="no_safety"/>
Modify this portalapp.xml file as follows:
       1.      NAVIGATION SERVICE, so you must add references to the following portal applications that define these services:
        com.sap.portal.navigation.service
        com.sap.portal.navigation.api_mimeservice
        com.sap.portal.navigation.helperservice
       2.      In the <application-config> section, create the following properties that help to define the security zone for all components and services in this application:
○     Vendor: String identifying the company or organization that provided the application, for example, sap.com.
○     SecurityArea: String identifying the security area for the application, for example, NetWeaver.portal.
       3.      In the <component-config> section for the mySiteMap component, create the property SecurityZone to define the specific security zone for the component.

Help me!! How to use JavaScript with JSP ??

I am using JDeveloper and I created a screen in JSP which uses a bean for database connectivity and retriving info onto the page.
The page has a ListBox where list items are populated from the database.My requirement is
whenever the list is changed the page shuold be refreshed with the selected item info.
I tried to use 'JavaScript' for triggering the event with 'onChange' event of the ListBox.But the event is not getting invoked. I think JavaScript is not working with JSP.
Please help me with how to Use javaScript with JSP or any other alternative where I can meet my requirement.
I have one more question...I have gone through the JSP samples in OTN and I am trying do download the sample 'Travel servlet' which show list of countries...etc
I have also gone through the 'readme' but I don't know how to extract .jar file.
I would be great if you could help me in this.

We have a similar need. We have used Cold Fusion to display data from Our Oracle Database. We have a simple SElect Box in HTML populated with the oracle data. When someone selects say the State of Pennsylvania. then we have an On change event that runs a Javascript to go get all the cities in Pennsylvania.
Proble we are having is that inorder for the Javascript to work , we currently have to send all the valid data.
Do you know of any way to dynamically query the the Oracle database in Javascript

Excel with JSP

Use of Threads with JSP's

Can you use threads in a web application that uses JSP's plus Servlets and Beans ?
We have a JRUN 3.1 application using JSPs, Servlets and Beans. Shortly after we went live it became apparent that any 2 users using the same object experienced problems as one object was overwriting another. In a panic the problem was solved by whacking SYNCHRONISED on all objects.
Now we want to write another application, are there strategies for using Threads with JSPs?
Would this be part of the webserver configuration or would the application be coded in a certain way ?
Please can you give me a simplistic answer or point me to some documentation that gives a simple overview.
Thanks Steve

Using java bean with jsp

hello friends,
i'm new to jsp. i want to create an html form that accepts username and a value from four radio buttons and display back the entered name and checked radio button's value using java bean.
i use the <jsp:setProperty id="" property="*"> method. i don't know how to access the radio buttons value from the html.
also when i use an additional field other than username the jsp page is showing error.
Please give me the correct method to use java bean with jsp in this circumstance.
thank you.

thank you, but i have a problem left. the case is like this.
i got the jsp and bean worked fine when i have a sinle input text field.
but when i added a second text field i recieved the following error.
javax.servlet.ServletException: basket.newbean.getUserPass()Ljava/lang/String;
     org.apache.jasper.runtime.PageContextImpl.doHandlePageException(PageContextImpl.java:825)
     org.apache.jasper.runtime.PageContextImpl.handlePageException(PageContextImpl.java:758)

     org.apache.jasper.servlet.JspServlet.service(JspServlet.java:236)
     javax.servlet.http.HttpServlet.service(HttpServlet.java:802)
where userPass is the new form element. I have made the subsequent chanes in my bean program and jsp file.
