Converting a class object back to a .class file

Hi,
How can i convert a class object back to a .class file ? Thanks

any pointers on how to do it then ? i don't have
access to the native codeIf I have understood you correctly, you have native code that generates bytecode. Currently you load the class this bytecode represents right into the classloader, but you want to save it to disk as a .class file. Right?
If so, you just have to get hold of that bytecode before it "disappears" into the classloader, and save it to disk. How you can best do this depends on exactly how you communicate with that native code.
If I have misunderstood your problem (and that's not unlikely), please try to be clearer.

Create Class objects from an Array of File Objects

Hi There,
I'm having extreme difficulty in trying to convert an array of file objects to Class objects. My problem is as follows: I'm using Jfilechooser to select a directory and get an array of files of which are all .class files. I want to create Class objects from these .class files. Therefore, i can extract all the constructor, method and field information. I eventually want this class information to display in a JTree. Very similar to the explorer used in Netbeans. I've already created some code below, but it seems to be throwing a NoSuchMethodError exception. Can anyone please help??
Thanks in advance,
Vikash

How to refer the parent class object from an inner class

Hi,
I have a class X, which contains an inner private class Y. Class X has a method getY which returns an object of class Y. Class Y has a method getParent. I want to return the object of parent class from this. The code is like this:
public inerface IY;
public class X {
private class Y implements IY {
public getParent {
// ... return the object of parent class which created the object of this inner class
public IY getY() {
return new Y();
Can somebody help me with this...

interface IY {
public class X {
    private class Y
        implements IY {
        private X parent;
        public Y(X x)
            parent = x;
        public X getParent()
            // ... return the object of parent class which created the object of this inner class
            return parent;
    public IY getY()
        return new Y(this);
}Filip

Confused about creation of inner class object of a generic class

Trying to compile to code below I get three different diagnostic messages using various compilers: javac 1.5, javac 1.6 and Eclipse compiler. (On Mac OS X).
class A<T> {
    class Nested {}
public class UsesA <P extends A<?>> {
    P pRef;
    A<?>.Nested f() {
        return pRef.new Nested(); // warning/error here
Javac 1.5 outputs "UsesA.java:11: warning: [unchecked] unchecked conversion" warning, which is quite understandable. Javac 1.6 outputs an error message "UsesA.java:11: cannot select from a type variable", which I don't really undestand, and finally the Eclipse compiler gives no warning or error message at all. My question is, which compiler is right? And what does the message "cannot select from a type variable" means? "pRef", in the above code, is of a bounded type; why is the creation of an inner object not allowed?
Next, if I change the type of "pRef" to be A<?>, javac 1.6 accepts the code with no error or warning message, while javac 1.5 gives an error message "UsesA.java:11: incompatible types" (concerning the return from "f" above). Similarly to javac 1.6, the Eclipse compiler issues no error message. So, is there something that has changed about generics in Java between versions 5 and 6 of the language?
Thanks very much for any help

How do I convert my smart object back into the layers I made it from?

I was working with 100 layers or so and i converted it to a smart object to work with easier. However some of the layers and layer modes don't interact properly with the background that is separate from the smart object. There doesn't seem to be an option to release layers within the smart object. I attempted to solve the problem by dragging the layers from the smart object editable file but it didn't line up within the original file...extremely frustrating. Any solutions? PS6 BETA Lion OSX

It was created inside the file. They were differnt dimensions though because the layers selected to become a smart object had different bounds beyond the canvas.
The issue was that once I dragged layers from the editable file that was the smart object I would attempt to realign them BUT I have so many adjustments with masks that we'ren't linked so they wouldn't move with my realignment move(even a control+t)...I ended up going back in and relinking them all(which took really long) in order to realign things.
But really it would be so much easier if i could have just clicked re-add layers to file or something.
No problem Howard, thanks anyway.

Can you convert a 3D object back into a 2D layer?

I am drawing out a map of a world and need to design the poles while the layer is in a 3D sphere to prevent distortion. In CS5, I would turn the layer into a 3D.sphere, draw on it to map out the land masses, then turn it back into a 2D layer and refine. However, I can't seem to do this on CS6. Is there a way for me to do that?
Thank you.

double click on the sub layer of the 3d layer in the layer panel. This should open the diffuse layer that you're working on.

[b]How to convert a Socket object in a C socket file descriptor[/b]

Hi all,
I need to make a getsockopt() call using JNI, but I don't know how to convert a Java Socket object in the integer corresponding to the socket file descriptor.
Thank you in advance!
Fernando

I was wrong in my previous post. FileDescriptor is used for PlainSocketImpl. This means I can give you a solution.
The solution does involve rebuilding some built-in Java classes to make certain fields accessible.
You have to modify access to three classes:
1. You can either use my SocketGetImpl or just rebuild java.net.Socket and change from
SocketImpl getImpl() throws SocketException {
to
public SocketImpl getImpl() throws SocketException {
2. In java.net.SocketImpl change from
protected FileDescriptor getFileDescriptor() {
to
public FileDescriptor getFileDescriptor() {
3. In java.io.FileDescriptor I would add the method
public int getFd(){ return fd; }
Then my test program becomes:
package myhack;
import java.io.*;
import java.net.*;
public class DoSock {
        public static void main(String args[]) throws Exception{
                Socket s= new Socket("mywebserver",80);
                System.out.println("s="+s);
                SocketImpl si = SocketGetImpl.getImpl(s);
                System.out.println("si="+si);
                FileDescriptor fd = si.getFileDescriptor();
                System.out.println("fd="+fd);
                System.out.println("fd int="+fd.getFd());
}And you still have to invoke as:
java -Xbootclasspath/p:. myhack.DoSock
or boot path pointing at jar file, etc.

Can a derived class catch base class object

can a derived class object catch a base class object
e-g if i have a class
class Test {
// code
}and
class Test2 extends Test {
}and lets say there is a method that return an object of Test (base class), so is it possible to write
Test2 t=getTestObj(); // i-e subclass holding base class objectif its not.. how can we do so? so that derived class should hold base class object....

sorry..
here is how it goes
i have a function a class
public Test getObj() {
// code
}The constraint is that i cant change the implementation of this above function.
Now when i call this function, it returns me a Test object. But i cant do
Test t=getObj();because the Test class is written purely in java whereas i want to use write a new Test class that implements the same functionality [using the above given function] in JNI.
so what i did, i created a new package [nativ] and created a class "Test" in that. But since i have to use the function that returns me Test and not "nativ.Test", so what i did, i inherited nativ.Test from "Test" so that the object might resolve the reference.
So this is it.. that i cant modify the function and i need some way to do it.. plz reply

Dealing with functions not in class Object

Hi,
while i was working on GJ i faced the following problem, when i write a generic class i have to take into my consideration those functions that i want to define for the row type class and not included in class Object (toSting() is in class Object but print() is not). of course every time i want to call print() from the generic class the compiler gives me an error becuz it is not in class Object.. is there anyway to get rid of this problem in a simple way without having to deal with more than one row type ?
thanks everyone

I think I see what you're getting at...the GJ compiler substitues Object for all unconstrained type parameters, and therefore tries to call methods on parametized type objects as if they were simply of type Object.
A solution would be to create a base class (or interface) AbstractRow that declares all the methods you need. Then constrain your parameters against AbstractRow. Eg:
public interface AbstractRow
public AbstractRow rowMethod();
public class MyClass<RowType extends AbstractRow>
public RowType doSomething(RowType rt) {
rt.rowMethod();
I think that should work. I'm not sure what you meant by "without having to deal with more than one row type." If you meant "without having to introduce an inheritance hierarchy," then no, this is not possible in GJ (as far as I can tell). If you meant "without having to write adapters for every single row type," then yes.

LOADJAVA이용시 JAVA CLASS OBJECT의 권한 문제

제품 : SQL*NET
작성날짜 : 2004-01-14
LOADJAVA이용시 JAVA CLASS OBJECT의 권한 문제
====================================
PURPOSE
Java Stored Procedure를 이용하기 위해 java class를 DB로 load할 때 loadjava를
이용할 수 있다. 이때 loadjava 수행시 권한 오류나, java stored procedure(JSP)의
owner와 다른 owner로 java class를 load하고 JSP에서 사용하는 경우의 권한
부여 방법 등을 확인해 본다.
Explanation & Example
1. loadjava와 dropjava의 간단한 실행 방법 및 관계된 objects들
loadjava command는 가장 간단하게 다음과 같이 지정할 수 있다.
-r option은 db에 load하고서 load된 java object를 compile하는 것이다.
os> loadjava -user scott/tiger -r LJTeset.class
이 문장을 수행하고 나면 다음과 같은 object가 생성된다.
즉, load되는 java class외에도 2개의 테이블과 2개의 index, 그리고 한개의
table이 생성된다.
loadjava를 수행하는 user는 이러한 object를 생성할 수 있는 권한이 있어야한다.
SQL> select object_name, object_type from user_objects;
OBJECT_NAME OBJECT_TYPE
CREATE$JAVA$LOB$TABLE TABLE
LJTest JAVA CLASS
JAVA$CLASS$MD5$TABLE TABLE
SYS_C002172 INDEX
SYS_C002173 INDEX
SYS_LOB0000029869C00002$$ LOB
loadjava후, 다시 dropjava문장을 다음과 같이 수행하는 경우, 이렇게 생성된
6개의 object가 모두 사라지는 것이 아니고 LJTest만 지워지고 나머지는
모두 그래도 남는다.
os>dropjava -user scott/tiger LJTest.class
즉, 일단 한번 loadjava를 수행하면 위에서 LJTest를 제외한 나머지 object는
항상 존재하게 된다.
2. loadjava시 다른 user가 java class이용할 수 있도록 하는 방법
loadjava시 load된 java class를 이용하여 JSP를 생성한 owner에게 다음과 같은
방법으로 권한을 부여할 수 있다.
os>loadjava -user scott/tiger -g public -s -r LJTest.class
os>loadjava -user scott/tiger -g eykim -s -r LJTest.class
이때 -g option이 권한을 부여하기 위한 option이며, -s를 지정하면 동일한
이름의 public synonym이 만들어져서 이 java class를 다른 schema에서도
이용가능하게 된다.
(NOTE) 이때, named PL/SQL에서 role을 통해 부여 받은 권한은 인식하지
못하는 제약사항이 loadjava시에도 그대로 적용된다.
즉, -g다음에 role명을 주는 경우 그 role을 가지고 있는 다른 user가
해당 java class를 이용하여 JSP를 만드는 경우 해당 java class를
인식하지 못하게 된다.
loadjava외에 직접적으로 SQL문장을 통해 권한을 부여하여도 된다.
SQL>grant execute on "LJTest" to scott;
여기서 주의할 점은 반드시 LJTest java class를 지정할 때 큰 따옴표(" ")를
표시하여야만 인식이 된다.
이것은 grant뿐 아니고 sql문장에서 java class를 reference할 때 항상 적용된다.
예를 들어 resolve시에 다음과 같이 하여야 한다.
SQL>alter java class "DBTrigger" resolve;
위의 loadjava 문장에서 -s option을 통해 public synonym을 생성하였는데,
이것은 sql문장을 통해 synonym을 생성하여도 같은 결과이다.
이때, user는 create public synonym권한을 가지고 있어야 한다.
이후 dropjava 수행이 필요한 경우, dropjava시 -s option없이 public synonym도
함께 drop되므로 drop public synonym도 필요하다.

Convert javadoc output back to java class.

Hi All,
I have the javadoc for a certain specification and would like to convert that to the java interface definition class. The generated source code would be used to generate the implementation class later.
Do you know of any utility that converts javadoc html back into java source code?
Thanks in advance,

Just use your browser's copy and past functions to cut the text out of the documentation and then paste it into a programming editor.
Delete the text and add a couple of semi-colons and you are all set.

The workaround is to add a custom converter class to your ViewController project like this
package oow2008.view;
import javax.faces.application.FacesMessage;
import javax.faces.component.UIComponent;
import javax.faces.context.FacesContext;
import javax.faces.convert.Converter;
import javax.faces.convert.ConverterException;
import oracle.jbo.domain.ClobDomain;
import oracle.jbo.domain.DataCreationException;
public class ClobConverter implements Converter {
     public Object getAsObject(FacesContext facesContext,
                               UIComponent uIComponent,
                               String string) {
       try {
         return string != null ? new ClobDomain(string) : null;
       } catch (DataCreationException dce) {
         dce.setAppendCodes(false);
         FacesMessage fm =
           new FacesMessage(FacesMessage.SEVERITY_ERROR,
                            "Invalid Clob Value",
                            dce.getMessage());
         throw new ConverterException(fm);
     public String getAsString(FacesContext facesContext,
                               UIComponent uIComponent,
                               Object object) {
       return object != null ?
              object.toString() :
              null;
}then to register the converter in faces-config.xml like this
<faces-config version="1.2" xmlns="http://java.sun.com/xml/ns/javaee">
<application>
    <default-render-kit-id>oracle.adf.rich</default-render-kit-id>
</application>
<converter>
    <converter-id>clobConverter</converter-id>
    <converter-class>oow2008.view.ClobConverter</converter-class>
</converter>
</faces-config>then reference this converter in the field for the ClobDomain value like this
          <af:inputText value="#{bindings.Description.inputValue}"
                        label="#{bindings.Description.hints.label}"
                        required="#{bindings.Description.hints.mandatory}"
                        columns="40"
                        maximumLength="#{bindings.Description.hints.precision}"
                        shortDesc="#{bindings.Description.hints.tooltip}"
                        wrap="soft" rows="10">

Problem with Dynamically accessing EJB Class objects in WL 7.0 SP1

I am trying to build a component which has the ability to instantiate and execute
an known EJB method on the fly.
I have managed to build the component but when I try and execute it I get a ClassNotFoundException.
I know that the EJB I am trying to invoke is deployed and available on the server,
as I can see it in the console, I also seen to have been able to get the remote
interface of the object, my problem occurs when I try and access the class object
so I can perform a create on the object and then execute my method
The code I have written is below:
private Object getRemoteObject(Context pCtx, String pJNDIName, String pHomeBean)
throws Exception {
     String homeCreate = "create";
     Class []homeCreateParam = { };
     Object []homeCreateParamValues = {};
try {
//This call seems to work and doesn't throw an exception
Object home = pCtx.lookup(pJNDIName);
//However this call throws a java.lang.ClassNotFoundException
Class homeBean = Class.forName(pHomeBean);
Method homeCreateMethod = homeBean.getMethod(homeCreate,homeCreateParam);
return homeCreateMethod.invoke(home, homeCreateParamValues);
} catch (NamingException ne) {
logStandardErrorMessage("The client was unable to lookup the EJBHome.
Please make sure ");
logStandardErrorMessage("that you have deployed the ejb with the JNDI
name "+pJNDIName+" on the WebLogic server ");
throw ne;
} catch (Exception e) {
logStandardErrorMessage(e.toString());
throw e;
Any advice would be really appreciated, I'm fast running out of ideas, I suspect
it has something to do with the class loader but I'm not sure how to resolve it
Regards

Hello Joanne,
Congratulations! I'm very happy that you've managed to fix your problem. It's
always essential to understand how to package applications when deploying on BEA
WebLogic. Usually, by throwing everything into an EAR file solves just about all
the class loader problems. :-) Let us know if you have any further problems that
we can assist you with.

The class loader was the culprit which is what I suspected all along.
As soon

away!!!!!

Hello Joanne,
As Mr. Woollen mentioned, I also believe it's a problem with the class
loader.
You need to be careful how you arrange your EJBs, because WebLogic has
a specific
method in which it loads classes in an EAR, JAR, and WAR file(s). Please
refer
to http://dev2dev.bea.com/articles/musser.jsp for more information about
BEA WebLogic
class loading mechanisms and caveats. Also, try printing out the various
methods
that are available on the object that was returned to you via reflection.
For
example, use the getMethods() method, which returns an array of Method
objects
that you can subsequently cycle through and print out the various method
names.
This way you can discover if the class found/returned to you is indeed
the one
you intend to locate.
Hope this helps,

I believe the issue is the home interface class for this EJB is not

If you do:
getClass().getClassLoader().loadClass(homeInterfaceClassName)
I suspect it will fail. Reflection still requires that the class be
loadable.

Your code should look like

Hi Ryan,
I also wanted to mention that if you do a "header search" in this
particular
newsgroup
with the search query as "reflection", you will see many previousmessages
regarding
reflection and EJBs. I believe you could learn a lot from thedifficulties
that
others have faced and solved.I tried that and although there was a number of similar cases noneof them
actually
seem to fix my issue. Thanks for the suggestion though
Are the EJBs that you are trying to access accessible via your
system
classpath?
Try to avoid having them accessible via the main system classpath,and
only bundle
them in your appropriate EJB jar files (contained in an EAR file,for
example).Maybe I should have laid the problem out a little clearer.
I have a number of EJB's bundled up in a JAR file which is hot deployedto
the
server. Within this first JAR file is an EJB (SSB) component that
needs
to
be
able to invoke a known method on another EJB. This second EJB may
or
may
not be
within the first JAR file but it also will be hot deployed.
The component trying to invoke the method on the 2nd EJB has to
be
able to
create
an instance of the 2nd EJB without actually knowing anything bar
a
JNDI
Name which
is passed in at runtime.
I can get as far as doing the
Object home = pCtx.lookup(pJNDIName);
This returned a class with the name
"com.csc.edc.projects.allders.httppostoffice.postman.PostmanBean_mp8qy2_Home
Impl_WLStub"
My problem seems to occur when I try and invoke the create method
Method homeCreate = home.getClass().getMethod("create", new Class[0]);
My code throws a java.lang.NoSuchMethodException at this point so
I
am
unable
to progress to the next step of :
Object bean = homeCreate.invoke(home, null);
So I can return the instantiated bean back to the calling client.
Why am I getting the NoSuchMethodException, is is because I am gettinga
stub
back rather than the home interface and if so how do I get the truehome
interface
from the bean
Thanks in advance

What is the advantage of using IB to create XIBs/Class Objects over coding?

Hi all,
I hoping someone can provide me some pros and cons as to when I should use IB to create XIBs and/or class objects as opposed to directly coding them.
For example, if I choose Apple's Template for creating a Navigation Based Application (cocoa touch), the project creates two NIB files - MainMenu and RootViewController.
However looking at one of demo apps SimpleDrillDown, it does not have a RootViewController XIB and instead creates it via code.
Another example from the same two apps is that the template generates a "Navigation Controller" class object in the Mainmenu.xib. SimpleDrillDown does not bother with this in the XIB, but uses code to generate the controller:
- (void)applicationDidFinishLaunching:(UIApplication *)application {
// Create the navigation and view controllers
RootViewController *rootViewController = [[RootViewController alloc] init];
UINavigationController *aNavigationController = [[UINavigationController alloc] initWithRootViewController:rootViewController];
self.navigationController = aNavigationController;
[aNavigationController release];
[rootViewController release];
// Configure and show the window
[window addSubview:[navigationController view]];
[window makeKeyAndVisible];
as opposed to the template which only needs this:
- (void)applicationDidFinishLaunching:(UIApplication *)application {
// Configure and show the window
// Navigation Controller is defined in MainWindow.xib
[window addSubview:[navigationController view]];
[window makeKeyAndVisible];
So what are the advantages of each approach. Why does apple suggest one approach and yet all its demos use another.
Any thoughts, answers gratefully received.
TIA, Michael.

You can do whatever you're comfortable with, but most of the best Cocoa programmers--the ones on the Mac, I mean--recommend putting everything you can into Interface Builder.
It's a little like the difference between writing a program to do a bunch of financial calculations and using a spreadsheet. Yeah, the program can do everything the spreadsheet can--and more besides--but you'll find it far easier to create, use and modify the spreadsheet.
Interface Builder takes away a lot of completely meaningless choices ("What order should I create the objects in? How should I name the variables? How should I create their frames? What order should I set the attributes in?"), leaving you with an interface optimized for creating and arranging objects, and allowing your code to focus on what you really do need to think about--your application's logic.
(By the way--part of the reason Apple's demos don't all use Interface Builder is that the very first SDK releases didn't have it. Back then, you had to create all your views programatically. Believe me, I have no wish to go back to setting autoresize masks manually. Now get off my lawn, whippersnapper.)
