How to instanciate Class Dynamically

I need to create instance and use class dynamically.
Suppose the codes instantiating an Object weather:
Weather weather=new Weather();but i want to do it dynamically, where the class name will be given as a String variable
in this case i will have
String className="Weather";then i want to replace the above Weather weather=new Weather(); to something like as:
Class.forName(className) instanceName=new Class.forName(className)() or somehow.
is it possible? Thank you for spending time to read my post.

Loading a Class by name and then creating an instance is easy enough. But because Java is a compiled language you can't just create a variable of a type unknown at compile time. The compiler needs to know what fields and methods are available up front, before any classes get dynamically loaded.
If you know the class you are going to load will be some subclass of "Weather", of if Weather is an interface and the class implements it, then you can create an instance and cast it to type Weather, then use the methods and fields of weather on it. If you don't have such information about the class you're going to load you need to access any objects created using reflection.

How to load classes dynamically?

Hi all!
I have folowing problem.
In my applet I need to load different classes form the same Web server. The main class is located in parent directory and different are in it's subdirectories. Security Manager allows to do this, but I find it difficult how to do it. Can you give me advise how to do it.
Thanks beforehand...

Create a package on the web side myserver.mypackage with subfolders ex1 ex2
THere place your class files to dynamical loading
Every class in package must starts from
package myserver.mypackage; statment
In paren directory for package creat a class where main applet class will be located
Create an inctance for submain classes as
(Class)Class.forName("myserver.mypackage.ex1.Class1").newInctance() - for class1 in ex1
(Class)Class.forName("myserver.mypackage.ex2.Class1").newInctance() - for class1 in ex2
It works. I'll send you example on e-mail.

How to load a Class Dynamically?

hi,
I have the following problem.I am trying to load a class dynamically.For this I am using ClassLoader and its Loadclass method.My code is like this,
File file = filechooser.getSelectedFile();
ClassLoader Cload = this.getClass().getClassLoader();
String tempClsname= file.getName();
Class cd =Cload.loadClass(tempClsname);
Object ob =(Object)cd.newInstance();
showMethods(ob);
In showMethods what i am doing is getting the public methods of the dynamically loaded class,
void showMethods(Object o){
Class c = o.getClass();
System.out.println(c.getName());
vecList = new Vector();
Method theMethods[] = c.getDeclaredMethods();
for (int i = 0; i < theMethods.length; i++) {
if(theMethods.getModifiers()==java.lang.reflect.Modifier.PUBLIC)
String methodString = theMethods.getName();
System.out.println(methodString);
vecList.addElement(methodString);
allmthdlst.setListData(vecList);
Now whenever i work with this i m getting a runtime error of CLASS NOT FOUND Exception..I know its because of Classpath..But i don't know how to resolve it??pls help me in this regard...
Also previously this code was working with java files in the directory in which this java file was present..How to make it work for java file in some other directory..pls help me in this regard...
Thanks in advance..

You sure didn't need to post this twice.
http://forum.java.sun.com/thread.jsp?thread=522234&forum=31&message=2498659
When you post code, please use [code] and [/code] tags as described in Formatting Help on the message entry page. It makes it much easier to read and prevents accidental markup from array indices like [i].
You resolve this problem by ensuring the class is in the classpath and you refer to it by its full name.

Hi all,
In my usecase I need to invoke a java class dynamically using any of the components like Button or link in jdeveloper.
How could we invoke a java class which has a main method in it dynamically.
Kindly come up with your help.
Thanks,

Hi john,
these are my Backing bean and action now at the run time when I am pressing a button which has to invoke cb3_action() method.
When I am clicking the button at the runtime I am getting the below error
Error 500--Internal Server Error

In the above code if you observe I have used "IDocument myDoc = new Document2004();" line. Here this Document2004 is a class which is in one of the external
jar files. xstream-1.3.1.jar , java2word-3.0_2011Aug02.jar , log4j-1.2.15.jar .
these are the jar files I found in net using which I can create a word file and add all the components like table and format the txt etc..
These jar files works in Tomcat, Jboss ,Struts
I can even run this class and got the file created.
But when I try to bind the method in ADF i am getting the error mentioned above.
Kindly help me on this. Sorry for posting similar question two times on the blog.
Sorry again if this question is wierd.
Thanks,

How to create a dynamic class

Hiya,
I want to create classes dynamically. I know that this can be done by extending ClassLoader and defineClass method. My problem is i dont know what goes in byte[] coz my program needs to get the class name, attributes and methods from the user.
For example something like visual modeler that loads up the UI than lets the user to create the classes, attributes and methods.
The generic class called gentity is as follows:
public class Gentity {
private String gname;
public Gentity(String mgname) {
gname=mgname;
public void setGname(String mgname)
gname=mgname;
public String getGname()
{return(gname);
This class will then be used in my main class which is as follows:
public class GentityClassLoader extends ClassLoader
Gentity customer=new Gentity("HSBC");
public static void main(String argv[])
byte b[]=new byte[1];
GentityClassLoader obj = new GentityClassLoader();
try{
// this is my problem here, i dont know what goes in bytes
Class cls = obj.defineClass(obj.customer.getGname(),b,0,b.length);
Class x=obj.loadClass(obj.obj.getGname());
obj.resolveClass(x);
System.out.println(x.toString()+"asdf");
}catch(Exception e)
System.out.println("Error");

How to assign a dynamic value to the value property of a button ?

Hi Folks,
I have a need, can i know how to assign a dynamic value to the value property of a button. Scenario is like follows...
This is a struts based web application
1. I have a file which consists of login user details (user name and his previlages) for a web application.
2. I got those user details, into a List.
3. When a user logged into the web app, in the home page there are few buttons. The type and number of buttons shown depends on the type of user/ user. (Buttons have different combination and the number of buttons available are not constant, they will vary from user to user).
4. for each button, there will be a different action. I can pass the value of a button to an action class, but here button must have a dynamic value.
Here is my test code:
<%
if (List != null)
for (int i = 0; i <List.length; i++)
%>
<html:submit property="rduname" value= "<%=List%>" onclick="return submitRdu('<%=List[i] %>');"/>
<%
%>
But my problem is how to assign a dynamic value to the value property of the button ( i know 'value= "<%=List[i]%>" ' will not work, just wanted show you guys).
Thanks in advance,
UV

Let me try i know am not good at JSP but do we need double quotes here
value= <%=List%>i think JSTL should help you about the dynamic thing

How to create a dynamic property in JavaFX ?
ObservableMap, ObservableMapValue, MapPropertyBase, MapProperty
Which one should I use. Can you give an example?

I'm not sure what you mean by "dynamic property"; can you be more explicit?
Your code creates two properties that can be read, written, and observed for changes, though it's probably better to use the standard naming scheme for the methods (e.g they should be getName(), setName(...) and nameProperty()).
An ObservableMap is an extension of the java.util.Map interface that can be observed; i.e. you can register a listener that will be notified if a key-value pair is added or removed from the map.
ObservableMapValue is an interface that defines an observable reference to an ObservableMap; i.e. it has a get() method returning an ObservableMap and a set(...) method taking an ObservableMap. You can register a ChangeListener which is notified when the set(...) method is called. It additionally functions as an ObservableMap, so you can also register listeners that get notified when key-value pairs are added or removed from the underlying observable map.
MapProperty and MapPropertyBase are effectively partial implementations of ObservableMapValue. SimpleMapProperty is a full implementation.
If you just need a single ObservableMap (i.e. not an observable reference to one), then the FXCollections.observableHashMap() factory method will provide one.

How to design class hierarchy to make use of Bimorphic inlining

I have a question regarding the optimum number of implementations you can have of an interface.
I have 1 interface and 2 main implementations. All the methods except one very rarely invoked method in those two main sub-classes are frozen using final.
interface Foo{
void hotMethod1();
void rarelyUsedMethod();
class A implements Foo{
final void hotMethod1(){.. .. ..}
//Non final!!
void rarelyUsedMethod(){.. .. ..}
class B implements Foo{
final void hotMethod1(){.. .. ..}
//Non final!!
void rarelyUsedMethod(){.. .. ..}
}Then there are many (more than 20!) sub-classes of these 2 main sub-classes - dynamically generated bytecode.
class Aee26671 extends A{
void rarelyUsedMethod(){.. .. ..}
class B33423 extends B{
void rarelyUsedMethod(){.. .. ..}
class C12ds423 extends A{
void rarelyUsedMethod(){.. .. ..}
and so on...All these second level sub-classes just override the rarelyUsedMethod().If in some caller method I do this:
x(Foo foo){
foo.hotMethod1();
}Does the Hotspot compiler recognize that there are only 2 possible targets because A and B have their implementations marked as final?
I've heard of Bimorphic inlining. But does it look just at candidate Sub-classes - in this case there are more than 2 sub-classes.
Or, does it realize that the actual candidate implementations of the hot method are just 2 (A and B) because they are "final" and optimize it?
PS: Does Hotspot do Bi or Polymorphic inlining?

Hi Ashwin,
as far as I understand, the bi-morphic case is really a special optimization that occurs when there are only two possible classes (not necessarily methods) involved. You can easily test that by adapting my newsletter: [Polymorphism Performance Mysteries Explained|http://www.javaspecialists.eu/archive/Issue158.html]
Here is how I tested it:
import java.util.Random;
public class PolymorphismTest {
private static final int UPTO = 100 * 1000 * 1000;
public static void main(String[] args) throws Exception {
    int offset = Integer.parseInt(args[0]);
    Foo[] tests = generateTestData(offset);
    System.out.println("Warmup");
    test_all(tests);
    System.out.println("Actual run");
    printHeader(tests);
    test_all(tests);
private static void test_all(Foo[] tests) {
    for (int j = 0; j < 10; j++) {
      run_tests(tests);
public static void run_tests(Foo[] tests) {
    long time = System.currentTimeMillis();
    test(tests);
    time = System.currentTimeMillis() - time;
    System.out.print(time + "\t");
    System.out.flush();
    System.out.println();
public static void test(Foo[] sources) {
    Foo t0 = makeRandomTest(sources);
    Foo t1 = makeRandomTest(sources);
    Foo t2 = makeRandomTest(sources);
    Foo t3 = makeRandomTest(sources);
    Foo t4 = makeRandomTest(sources);
    Foo t5 = makeRandomTest(sources);
    Foo t6 = makeRandomTest(sources);
    Foo t7 = makeRandomTest(sources);
    Foo t8 = makeRandomTest(sources);
    Foo t9 = makeRandomTest(sources);
    for (int i = 0; i < UPTO / 10; i++) {
      t0.hotMethod1();
      t1.hotMethod1();
      t2.hotMethod1();
      t3.hotMethod1();
      t4.hotMethod1();
      t5.hotMethod1();
      t6.hotMethod1();
      t7.hotMethod1();
      t8.hotMethod1();
      t9.hotMethod1();
private static Foo makeRandomTest(Foo[] sources) {
    return sources[((int) (Math.random() * sources.length))];
private static void printHeader(Foo[] tests) {
    System.out.print(tests[0].getClass().getSimpleName());
    System.out.print('\t');
    System.out.println();
private static Foo[] generateTestData(int offset)
      throws Exception {
    switch (offset) {
      default:
        throw new IllegalArgumentException("offset:" + offset);
      case 0:
        return fillSources(A.class);
      case 1:
        return fillSources(A.class, B.class);
      case 2:
        return fillSources(A.class, B.class, Aee26671.class);
      case 3:
        return fillSources(A.class, B.class, Aee26671.class, B33423.class);
private static Foo[] fillSources(
      Class<? extends Foo>... fooClasses)
      throws Exception {
    Foo[] sources = new Foo[1000];
    Random rand = new Random(0);
    for (int i = 0; i < sources.length; i++) {
      int offset = Math.abs(rand.nextInt() % fooClasses.length);
      sources[i] = fooClasses[offset].newInstance();
    return sources;
}On my machine, the results are as follows:
1 class: average=0, stdev=0
2 classes: average=103, stdev=4
3 classes: average=672, stdev=26
4 classes: average=666, stdev=0.4
As I thought, the bi-morphic optimization is only applied on a class instance basis, rather than a method basis.

Loading Jar classes dynamically - 10 Duke points

How can I load a jar class dynamically if it relies on say other interface? Example is, if I have three classes read from the jar file, Test.class, Test1.class and Testable.class
and "class Test implements Testable..."
If I load the Test.class, how do I tell my own class loader that Testable class is along the way, instead of getting a java.lang.NoClassDefFoundError: Testable
Need example source that works for this type of problem.

In my report I have to get these record typpes as field name dynamically whichever is available in that lookup and record values against them.
its a BI Publisher report.
please suggest

if you have data in db then you can create xml with needed structure
and so you can create bip report
do you have errors or .... ?

Hi Patricia,
is it working for restricted key figure and calculated key figure ??
Note Number Fisc Period Opening Days
1 1 2
2 1 3
3 1 0
because I have other restriction, so I create two restricted key figure..
RK1 with restriction : Total Number of Note,
RK2 with restriction : Total Opening Days ,
then I Created a calculated key figure, average opening days in a period
CK1 = RK2 / RK1..
in this case, I am not sure if it will work or not..
for example, during RK2 calclation, it might be this   2+3 = 5, the line with 0 will be ignored..
during RK1 calcualtion, it might be 1 + 1 + 1 = 3. ---> Not sure in this case, the line with opening days 0 will be calculated or not..
could you please confirm..

How do I use dynamic JSP vars in a form tag with implicit sessions?

I'm using iAS 6 SP4 and 'lite' sessions w/ sticky LB on Win2K for development and need to use a dynamic variable (via an = scriptlet) to specify the URL a form tag's ACTION method posts to. The implicit URL session encoding attempts to add the hidden input tags to the form but part of it is getting cut off. If I remove the dynamic var scriptlet from the form tag it works fine. How can I use dynamic vars and implicit URL session encoding?
Here's my code sample:
<FORM NAME='Create' METHOD='POST' ACTION='<%= servletRootStr %>CreateServlet' TARGET='_top'>
Output is:
<FORM NAME='Create' METHOD='POST' ACTION='http://my.server.com/NASApp/WebStuffApp/Create' TARGET='_top'>T NAME="GXHC_gx_session_id_" TYPE="HIDDEN" VALUE="GXLiteSessionID--8351372849698357580" ></INPUT><INPUT NAME="GXHC_GX_jst" TYPE="HIDDEN" VALUE="d692bc3d662d6164" ></INPUT>
Because the <INPUT> tagon the first session var is cut off, up to the T, the page obviously fails. Can this be fixed with a config setting, or is it a bug in iPlanet??

Thanks for helping me Anurag.
The problem I tried to solve was that I want the result from my service methods
in XML format. I thought a callback/polling was the best alternative, am I right?
Since the callback option doesn´t work I will try to poll the service.
Are there any other options for solving my problem??
Thanks again!!

Andrej,
I guess you are trying to invoke a Webservice which defines a callback
method
from a JSP, and want the JSP to handle the callback made by the webservice.
For a client to be able to handle a callback made by a Webservice, it
has to be
a web service in itself.
Even some web service tools do not support 'Solicit responses' and hence
they
would not generate handlers for the callback methods by default. You
can download
a callback WSDL in such cases and implement it on the client side. The
server
side web service will then callback to that webservice.
The other option to callbacks is to use polling methods. This can be
done from
any client such as Java client/ JSP client or a .NET client.
Hope this helps. Let me know if you have any further questions.
Regards,
Anurag
