How to create an object of our own class by using Class.forName()??

how to create an object of our own class by using Class.forName()??
plzz anser my qustion soon..

Class.forName does not create an object. It returns a reference to the Class object that describes the metadata for the class in question--what methods and fields it has, etc.
To create an object--regardless of whether it's your class or some other class--you could call newInstance on the Class object returned from Class.forName, BUT only if that class has a no-arg constructor that you want to call.
Class<MyClass> clazz = Class.forName("com.mycompany.MyClass");
MyClass mine = clazz.newInstance();If you want to use a constructor that takes parameters, you'll have to use java.lang.reflect.Constructor.
Google for java reflection tutorial for more details.
BUT reflection is often abused, and often employe when not needed. Why is it that you think you need this?

How to create a object for IPageItemControlData?

how to create a object for IPageItemControlData?

From the header comment you'll see that IPageItemControlData is an Interface of PageItemWidget. That must've been an InDesign 1.0 or 1.5 feature predating kPageItemBoss, because except for the same comment even in InDesign 2.0 SDK the only further reference is a copy in the comment of its sibbling IFrameControlData which was removed with InDesign CS.
The IID and kPageItemControlDataImpl are probably only around because deep under the hood there must be some kind of conversion provider waiting to do its job on a very old document.
I guess the closest in today's functionality will be IHierarchy.

How to create Activex object for my Visual C++ object

Hi,
I am working on development on Acrobat 9.0 SDK. I am facing problem is that I can compiled Visual C++ source code to an api. I can test functions on this api on Acrobat 9.0 windows, but I could not test it on IE web browser, because I don't know how to create Activex object from my Visual C++ source code or its api.
I read Acrobat 9 SDK document and found under C:\Acrobat 9 SDK\Version 1\PluginSupport\Tools\Visual Studio App Wizard has two files: Acro9PIWizInstaller.msi and setup.exe. I am not very sure those file are the key to help me to create Activex objects for my api. Are they the one I need to create Activex object? If not, could you please advise me how to create Activex object for my api or C++ codes.
Thanks a lot for any of your comments or advices.

Hi lrosenth,
Thanks a lot for your information.
My question is, on Javascript how do I call a function from .api. Below is my very simple test.
I got a function on BasicPlugin.cpp under C:\Acrobat 9 SDK\Version 1\PluginSupport\Samples\BasicPlugin. See below.
I added BasicPlugin.api on C:\Program Files\Adobe\Acrobat 9.0\Acrobat\plug_ins
     ACCB1 int ACCB2 MyPluginCommand() {
          int num = 5;
          return num;
On my HTML file, I create an <Object> below:
    <OBJECT id="acrobatapp"
            classid="clsid:85DE1C45-2C66-101B-B02E-04021C009402">
    </OBJECT>
    <OBJECT id="acrobatpdf"
            classid="clsid:CA8A9780-280D-11CF-A24D-444553540000"   >
        <Param name="SRC" value="http://www.adobe.com/devnet/acrobat/pdfs/acrobat_digital_signature_appearances_v9.pdf">
   </OBJECT>
On my Javascript. I call function MyPluginCommand() as below, but it is not working. How do I call function MyPluginCommand() on Javascript?
     var acrobatapp= document.getElementById("acrobatapp");
     var num= acrobatapp.MyPluginCommand();
     alert(num);
Thanks for your support,

How to create a window with its own window border other than the local system window border?

How to create a window with its own window border other than the local system window border?
For example, a border: a black line with a width 1 and then a transparent line with a width 5. Further inner, it is the content pane.
In JavaSE, there seems to have the paintComponent() method for the JFrame to realize the effect.

Not sure why your code is doing that. I usually use an ObjectProperty<Point2D> to hold the initial coordinates of the mouse press, and set it to null on a mouse release. That seems to avoid the dragging being confused by mouse interaction with other nodes.

How to create an object alive all the time on a server side

Hi,
I work on an Intranet with J2EE technologies. I need an object to do several tasks in background on the server side. Like start scheduled processes on a database and files, stocked on the server. What is the way to do this. I thought to use the JNDI by declaring the object in the Deployement Descriptor, and to manage a timer within.
I don't know if this works.
Anyway, my question is how to create an object on the server that is ALIVE ALL THE TIME and visible by the other objects running in the same VM.
Thank's.

This may not be the correct design, but I had success doing the following:
1. Create an Stateless EJB that does a task, i.e. update a database table.
2. Create a subclass of java.util.TimerTask to call the EJB methods.
3. Kick off the TimerTask from a servlet.init method.
Seems to work pretty well to do scheduled tasks, such as refreshing lookup tables. I would imagine the same could be done with an MBean, but I haven't had time to fully understand JMX yet. (It's on the list).
As for event driven procedures, that can be done through a servlet interface.
You may also wish to review a scheduler here: http://www.part.net/quartz.html. Note, I have NOT even looked at it yet, so I have no clue if it's any good. But, it is on my list of tools to evaluate (that's a long list) someday when my head's above water. Have a look, and caveat emptor.
Hope this helps,
Perry Tew

How to create an object of a class?

plz read the question carefully ..
how to create the object of a class by giving the class name as an String
suppose i have a java file name:" java1.java ".
so now how to create an object of this class "java1"by passing a string "java1"..

thanks but still i have problem..
i have created the object but now i m unable to do anything with that created object..
i have coded like this..
Object o= Class.forName("java1").new Instance();
after this i m unable to do anything with the object 'o'..So why did you create the instance? You can also get all methods using reflection, but that is probably not what you want to do. You should instead let the class implement an interface and cast the created object into that interface ans call the methods that you want to call.
KajI agree with Kaj. If you need to use a class that's unavailable at compile time, you should create an appropriate interface by which to refer to the class and then you create instances reflectively and access them normally via their interface (which is called reflective instantiation with interface access)

How to create an object class programmatically?

Guys,
I need your help. If possible with a simple example of how to do it.
I need to create an aplication that read an specification of a repository type from a file and then creates it inside my BEA Repository. The problem are few:
1 - How to Create an Object Class programmaticaly?
I looked at documentation of ObjectClassOps but havent figured out how to do it.
2 - How to Create a Property Definition programmaticaly?

Sorry, ITypeManager only exists in 9.2. If you are working on 8.1, then the previous example becomes:
RepositoryManager repositoryMgr = RepositoryManagerFactory.create();
//connect to the repository
repositoryMgr.connect();
//get ObjectClassOps
ObjectClassOps ocops = repositoryMgr.getObjectClassOps();
ID repId = new ID();
repId.setRepositoryName(repositoryName);
PropertyDefinition[] pds = new PropertyDefinition[1];
pds[0] = new PropertyDefinition(repId, "stringProp", null, Property.STRING, false, false, false, false, false, null);
ObjectClass oc = new ObjectClass(repId, "myType", null, pds);
oc = ocops.createObjectClass(oc);

How to create an object within the same class???

hi im just a newbie
i v been always creating an object from the main class..
but how to create an object inside the same class??
i got main and students class
the main got an array
Students[] stu = new Students[]
and i got
stu[i] = new Students(id,name);
i++;
but i wanna do these things inside the Students class..
i tried ..but i got errors.....
how to do this
.

javaexpert, :)
I really have no idea what you are trying to do since you say you've always been creating an object from the main class, yet you always want to create an object inside the same class.
I'll assume that you have an object in the main class that you are trying to access from the Students class.
If you are trying to access objects that are contained within the main class FROM the Students class, then know that there are two ways of doing so, one being static, and the other dynamic (look up definitions if unclear):
1.) make the objects in the main class both static and public and access the the objects using a convention similiar to: Main.object; It's important to note that Main is the name of your main class, and object is a static object. There are better ways of doing this by using gettter/setter methods, but I'll omit that tutorial.
2.) Create a new instance of the main class and access the objects using a similiar fashion: Main myInstance = new Main(); myInstance.myObject;
You should really use getter and setter methods but I'll omit the code. In terms of which approach is better, step one is by far.
I don't mean to be condecending, but you should really brush up on your programming skills before posting to this forum. This is a fundamenetal concept that you will encounter time and time again.

How to create an object of inner class

hi i don't know how to create an object of an inner class..
i got something like
class Abc{
private class Abcd {
like this and i want to create an object of Abcd so that i can use some of method
there..
i think i should create the outter class object first right? but not sure
the syntax.. i tried something like
Abc.Abcd justTry = new Abc.Abcd()
something like this..but not work..
help me plz. ...

If the nested class (that's not technically an inner
class you have there) is not static, then you can't
refer to it with OuterClassName.InnerClassName any
more than you can refer to any other member--method
or variable--with ClassName.staticMember.
You need an instance.
It's been a while since I've created an instance of a
non-static nested class from outside that clsas, but
I think it's something like this: Outer outer = new Outer();
outer.Inner inner = new outer.Inner();
Actually, I think it is this:
Outer outer = new Outer();
outer.Inner inner = outer.new Inner();Can't test it now though, gotta go to Taco John's for TACO TUESDAY!!!!
Gotta love them crunchy shell bean tacos!!!

How to create an object only if not exist?

how to create an object only if not exist? is it possible?
if not what can I do?
Thanks.

Well, the jsp:useBean tag is a great way to do things.
But another way is:
<%
      MyObjectType myObject = null;
      if(session.getAttribute("myObject"))==null) {
         myObject = ... ; //initiate your object
         session.setAttribute("myObject", myObject);
      myObject = (MyObjectType) session.getAttribute("myObject");
%>As you can see, this is more messy, but you can do it.
