Urgent... java.io , java.lang.class..
Hi there,
When i choose the file from JFilechooser, for example is a .class file, how do i make the .class file be read by java.lang.class as a class object, so i can get information from the class object ?
Is it related to java.io that make it become stream or something.
Is urgent for my school assignment, please help, Thanks in advance.

Thanks in advance.First of all, java.lang.class does not exist. Just java.lang.Class.
1. Read the content of a file into a byte[]
2. Use defineClass method from ClassLoader in order to get the Class object (you can use the system class loader obtained by static method ClassLoader.getSystemClassLoader() )

Urgent Plz reply: java.lang.Class not found exception
Hi All,
I am novice to j2me, I am tryiing communicate data between client and Java server. I have given project name client and midlet class name FileViewer.java.
It is compiling succesfully

ThanxNo, the "-g" version just means it has the debug flag turned on when they compile it.
Your problem is CLASSPATH and how to set it properly.
Use the -classpath option on java.exe when you run. Read the javadocs on the tools to find out how.

Hi,
I configured scenario FILE TO JDBC, the sender channel is successful but in the receiving I am getting the error that java.lang.class not found.
In the receiver communication channel, I gave "com.microsoft.jdbc.sqlserverdriver".
what database connection parameters need to be given??
Thanks,
Satish.Whats your database ?
As Suresh said, did you deploy your JDBC driver ?
How to ?

Java.lang.Class- getFields() results in JVM crash when called through JNI
From a C++ application, I use Invocation APIs to create a JVM and call some Java methods using JNI
I get a crash in jvm.dll with EXCEPTION_ACCESS_VIOLATION
when I try to call "getFields" method of java.lang.Class in order to get the Fields of the java class
This method call, should return a java/lang/reflect/Fields[] on success
I am able to get the method ID of this method by using pEnv->GetMethodID(..)
However, when I call this method using CallObjectMethod(..), HotSpt JVM crashes with access violation with the dump given below.
Any clues on how to debug and find the problem?
Or has anyone tried getting the fields of a Java class from C++ by calling reflection APIs uing JNI?
Thanks in advance!
Sample code
jclass testerClass = pEnv->FindClass("com/test/Tester");
jmethodID cid = pEnv->GetMethodID(testerClass,"<init>","()V");
if(NULL == cid)
pEnv->ExceptionDescribe();
jobject testerObject = pEnv->NewObjectV(testerClass, mid);
jmethodID mid = pEnv->GetMethodID(testerClass, "getClass",
"()Ljava/lang/Class;");
jobject clsObj = (jobject)pEnv->CallObjectMethod(testerObject, mid);
pEnv->ExceptionDescribe();
jclass jCls = pEnv->GetObjectClass(clsObj);
jmethodID midGetFields = pEnv->GetMethodID(jCls, "getFields",
"()[Ljava/lang/reflect/Field;");
jobjectArray jobjArray = (jobjectArray)pEnv->CallObjectMethod(testerObject, midGetFields);
pEnv->ExceptionDescribe();

# Java VM: Java HotSpot(TM) Client VM (1.4.2_03-b02 mixed mode)You are right, I tried getting the java.lang.Class reference for the com.test.Tester by calling getClass() on com.test.Tester
And using this jclass reference for java.lang.Class, I tried getting the method ID of getFields and eventually the Field[]
Thanks for the help
I have some more questions.
Assumption - Using JNI, I got the fields array of com.test.Tester and I am iterating through the fields
1.Assuming that the Tester class had an Integer field say m_nIntVal, then once I get the jobject equivalent of this Field in C++.
Now I need to get the type of the field (I call the method java.lang.reflect.getType() from JNI)
This gives me a jclass reference to it's type i.e java.lang.Integer
2.I need to get the name of this type i.e I want to get the name of the type in a string as "java.lang.Integer"
For this, on the jclass reference of java.lang.Integer got in Step 1, I call getClass() from JNI (to get the java.lang.Class) and then getName()
Now, for calling getClass(), I need a temporary object reference corresponding to the jclass of java.lang.Integer, The problem is that Integer does not have a default constructor, so my call to create the jobject fails.
But, since I do not know that I am constructing an Integer (remember that is what I am trying to find out - getType), I cant pass any values to constructor
Now, how do I go about creating a jobject of Integer, without knowing that I am constructing that, as this does not have a default constructor without parameters
Also, I tried using AllocObject to get the jobject and then tried to get the method ID of getClass(). Even this failed
3. If the com.test.Tester class had a primitive "int" field, say m_nPrimitiveInt
for which java provides a Class representation, I am able to get the jclass reference to the type of m_nPrimitiveInt
Now, how do I get the name of the type as "int" in a string?
Forllowing a similar procedure like in Step 2 fails when I try to pass the jclass reference to the type of m_nPrimitiveInt to the GetMethodID
with the error FATAL ERROR in native method: JNI received a class argument that is not a class
Can you tell me what is the way out?
Thanks in advance,
Also, can I mail you with some doubts that I have? If its ok, please contact me at [email protected] -
Problems with java.lang.Class in JDK1.3
Hi,
I have 3 problems with the reflection in java.lang.Class:
1) In the specification of method java.lang.Class.getDeclaredFields() is wrote:
"Returns .... This includes public, protected, default (package) access, and private fields ..."
This means, that all private fields should be return too. But some private methods are not given back. ????
2) In java.lang.Class.getDeclaredMethods()
some public methods are not return. ????
3) In java.lang.Class.getDeclaredMethods()
If Class is an interface. The same problem like 2) ????
Are they errors of java.lang.Class in JDK1.3 ????
Thanks & sincerely.Not sure it makes a difference, but you left off the last part of the quote:
This includes public, protected, default (package) access, and private classes and interfaces declared by the class, but excludes inherited classes and interfaces.
Are these missing methods from inherited classes, or are they declared in the class itself? -
Is a jclass object always a java.lang.Class object?
In a native method, I'm receiving a jobjectArray called "args" as a parameter. I'm writing this:
jclass cls1 = env->GetObjectClass(args);
jmethodID mid1 = env->GetMethodID(cls1, "isArray", "()Z");
but this returns 0, indicating there is no isArray in the jclass returned by GetObjectClass. On the other hand, this works:
jclass cls2 = env->GetObjectClass(env->GetObjectClass(args));
jmethodID mid2 = env->GetMethodID(cls2, "isArray", "()Z");
Why??
When I call getMethods() (via JNI) on cls1, I get only the methods of java.lang.Object. When I do that on cls2 I get the methods of java.lang.Class.Oops, I answered my own question. The jclass object represents the class of args, so its methods are those of the class of args, not those of java.lang.Class. I was misinterpreting what GetMethodID does -- it gets methods that would be returned by getMethods() in the Class object, not the methods of the Class object.

How to use java.lang.Class.getMethod() and java.lang.reflect.Method.invoke(
I want to call a specified method of one class dynamically. I use the method
"getMethod()" in package "java.lang.Class" to get method and "invoke()" in
" java.lang.reflect.Method " to invoke method.
The problem is as following :
1. There are two argument in this method "getMethod(String MethodName , Class[] paremterTypes)" in package "Class". I have no idea about the second parameter " Class[] parameterTypes ".what does the argument exactly mean ?
2. There are two argument in the method "invoke(object obj, object[] obj)" in package "Method".
I have no idea about the second parameter "object[] obj ".what is mean ?
I pass " null " value to it and it works.But i pass anothers ,jvm will throw exception.I have a generic Method Executer that has a method like
public Object execute(String className, String methodName, Object args)
String fullClassName = packageName + className ;
Class delegateClass = Class.forName(fullClassName);
BaseDelegate delegate = (BaseDelegate)delegateClass.newInstance();
Method method = null;
if (args == null)
method = delegateClass.getMethod(methodName, new Class[] {});
obj = method.invoke(delegate,new Object[] {});
else
method = delegateClass.getMethod(methodName, new Class[] {args.getClass()});
obj = method.invoke(delegate, new Object[]{args});
}This seems to have problems when I call the method from a class like:
execute("CategoryDelegate", "getCategoryById", new Integer(4144));(I get a NoSuchMethodException)
The method I am trying to execute in CategoryDelegate looks like:
public Category getCategoryById(int categoryId) throws DelegateExceptionI think it has to deal with the difference in the way we handle Primitive Wrappers and Objects. Wrapper we have to use Interger.TYPE and with the rest of the Objects we have to use obj.class.
Am I doing something wrong here? Any suggestions to make it work for primitive wrappers as well as Objects? -
UI Error 'Method clone not found in class java.lang.Class'
When attempting to view an application window in the User Interface error I receive the error 'Method clone not found in class java.lang.Class'. The window will run correctly when I execute the application and other objects on the window are displayed correctly in the UI editor.
Within the window class I have used the following line of code to clone a reference list of values that is loaded just once when the application starts up: -
dsDefaultComboBoxModel priorityComboBoxModel = (dsDefaultComboBoxModel) dsReferenceLuLists.priorityComboBoxModel.clone();
And then this line of code to create a combo box: -
dsGuiComboBoxRefelu priorityComboBox = new dsGuiComboBoxRefelu(priorityComboBoxModel,ReportWindowSql.priorityCodeBuffer);
And then later on the combo box is displayed.
detailsArea.add(priorityComboBox, new XYConstraints(250,10,dsGlobalVariables.gvFieldWidthLarge,-1));
'dsDefaultComboBoxModel' is defined as follows: -
public class dsDefaultComboBoxModel extends DefaultComboBoxModel implements Cloneable
public dsDefaultComboBoxModel()
public Object clone()
try
return super.clone();
catch ( CloneNotSupportedException e )
// Shouldn't happen.
throw new InternalError( e.toString() );
This error occurs using the latest v903, but was also present in previous versions of JDeveloper.
At the moment this means that I did to execute the window in order to see all of the GUI elements that are displayed. As on option I could use something other than the clone method, but it seems to be such a nice way of copying the static reference lists.
Thanks for any help.Hi Darren,
My guess is that since DefaultComboBoxModel doesn't implement Cloneable, you can't call super.clone(). Does your code compile?
Later.

How to call a java program in javafx class(Urgent) and even vice versa
Hi all,
Here I have two questions:
1)
Please let me know how to call a javafx in java program...
I tried with the following code but it is not working..
The below is the java program in which I made a call to the Fx program.
FxMainLauncher.java
import net.java.javafx.FXShell;
public class FxMainLauncher {
public static void main(String[] args) throws Exception {
FXShell.main(new String[] {"HelloWorld.fx"});
2) How to call a java program in javafx class
Here is my javafx program
import check.*;
import javafx.ui.*
var instance = new MyJava();
//visible:true
System.out.println("Number is: {instance}");
Here is my java program
public class MyJava {
public static void main(String args[])
System.out.println("JAVAFX TO JAVA");
Even this is not working please let me know ASAP
Thanks in advance,
V.SrilakshmiGOT IT !!!
I had to change the name of the method in .h file generated by javah command. On doing
javac -d ../../classes HelloWorld.java
go to the ../../classes directory (where you have the class file) and do
javah HelloWorld
I got a HelloWorld.h file in which I had
JNIEXPORT void JNICALL Java_HelloWorld_display(JNIEnv *, jobject);
I added the package name too:
JNIEXPORT void JNICALL Java_GUI_HelloWorld_display(JNIEnv *, jobject);
The HelloWorldImp.c file should have the same name (ie with package) and be in the same directory(ie ../../classes)
compile and build the shared library to get "libhello.so" file
gcc -c -fPIC -I/usr/lib/j2sdk1.3/include -I/usr/lib/j2sdk1.3/include/linux HelloWorldImp.c
gives .o file
gcc -shared -o libhello.so HelloWorldImp.o
gives .so file
then run java with the command in my first message. It works.
Thanks for the reply "thedracle". -
Urgent help needed(java frames)
Hi,
I need urgent help for correcting a piece of code.
I have written a piece of code for building a gui with some buttons, drawing some geometric shapes.The code consists of two files called Graph and Frame.
The problem I suppose in the last part of the Graph file, which Rectangle and Circle are called together, the only shape that the program draws is rectangle.Here is the code:

MarinaHi,
You are very lucky that I'm currently boored. You should never tag a question as urgent. It might be urgent to you, but not to us who answer. And you should also use code formatting when you post code (see the formatting tips, or use the code-button).
I made some changes to your Graph class. The most important thing is the abstract draw method that I added to the GeomFigur class.
import java.awt.*;
import javax.swing.*;
import java.util.*;
public class Graph extends JPanel {

Point p1, p2;
public Line(Color c, Point p1, Point p2) {
super(c);
this.p1 = new Point(p1);
this.p2 = new Point(p2);
public String toString() {
return "Line from " + p1 + " to " + p2;
public void move(Point dist) {
p1.move(dist.x, dist.y);
p2.move(dist.x, dist.y);
class Rectangle extends Line {
public Rectangle(Color c, Point p1, Point p2) {
super(c, p1, p2);
public String toString() {
return "Rectangle from " + p1 + " to " + p2;

System.out.println("Draw rectangle at " + p1 + " with color " + color);

public Circle(Color c, Point centre, int radius) {

g.setColor(Color.black);
g.drawOval(centre.x, centre.y, 20, 20);

g.fillOval(centre.x, centre.y, 20, 20);

Java.rmi.UnmarshalException: skeleton class not found but required for clie
Hello everyone,
I am new to RMI and getting a strange exception. I am using Java 1.5.0_07 both on client and server. They are running on the same machine, the rmi registry is started inside the server application.
I am wondering why java complains about skeletons, I thought they are automatically created when using java 5.0?
Please have a look at the stacktrace below.
Thank you for your help.
Best Regards
Patric
