Reflection Classes with the same name

Hi!
I have a big problem with reflection. I want to reflect lots of stuff (methods, variables...) in a lot of classes with the same name immediately one after the other. It's like
copy the file for the analysis to the right place
do reflection and get results
copy next file for analysis
Important to note is, that all of the files that should be reflected have the same name.
When I run the programm, he always only reflects the first file I gave for analysis, although I know the copying-stuff works and the new file would be there for analysis (but he does not seem to load/use it).
Any ideas what i could do?
Thanks!

I'm not sure if i'm authorised to tell too much
details, but i have to do some automated software
analysis and therefore I need to know whats inside of
a class and string search would not be appropriate.Why not ? What aspects of the class are you trying to examine ?
They have the same name, because they are delivered in
that form from a third party and it would be too much
effort (and to much risk of errors) to rename them.Sure, if they're delivered as class files, you're unable to rename them. Without knowing more I can't advise you further.
Why are you interested that much in that topic? Do you
have to perform a similar task?No, I'm trying to determine if reflection is the right tool for the job. Frankly it doesn't sound like it is. But since you're not authorised to tell me more, I can't help you more.

To access a method frm a class derived frm a base class with the same name

Here' s an example:-
class TestA {
public void start() {
System.out.println("TestA");
class TestB extends TestA {
public void start() {
System.out.println("TestB");
}In main method I do this:-
TestA testA = new TestA();
TestB testB = new TestB();
((TestA)testB).start();Output :-
TestB.
Now when i define the method as static :-
class TestA {
public static void start() {
System.out.println("TestA");
class TestB extends TestA {
public static void start() {
System.out.println("TestB");
}Then output is :-
TestA.
Can anyone let me know that when i say ((TestA)testB).start(); i.e i am type casting TestB obect to it base call then TestA should be printed but it doesn't print but when i declare method as static is does print TestA.
Thanks,
Heena

Secondly, when i say ((TestA).testB).start(); output is TestB. But when i define start() method as static output is TestA. I need clarity for the same.In the static case, all that the compiler is interested in is the class of the expression before the ".". Because you've put in an explicit cast the type of expression is assumed to be TestA the compiler doesn't know what kind of object will actually be referenced at runtime. In the static case which method is called is determined at compile time.
In the instance method case what determines the method called is determined the class of the actual, run time, value of the expression, and despite your cast, the actual value is still a reference to a TestB instance, so the TestB method is called. In the instance case which method called is determined at run time.

How do I call methods with the same name from different classes

I have a user class which needs to make calls to methods with the same name but to ojects of a different type.
My User class will create an object of type MyDAO or of type RemoteDAO.
The RemoteDAO class is simply a wrapper class around a MyDAO object type to allow a MyDAO object to be accessed remotely. Note the interface MyInterface which MyDAO must implement cannot throw RemoteExceptions.
Problem is I have ended up with 2 identical User classes which only differ in the type of object they make calls to, method names and functionality are identical.
Is there any way I can get around this problem?
Thanks ... J
My classes are defined as followes
interface MyInterface{
     //Does not and CANNOT declare to throw any exceptions
    public String sayHello();
class MyDAO implements MyInterface{
   public String sayHello(){
          return ("Hello from DAO");
interface RemoteDAO extends java.rmi.Remote{
     public String sayHello() throws java.rmi.RemoteException;
class RemoteDAOImpl extends UnicastRemoteObject implements RemoteDAO{
     MyDAO dao = new MyDAO();
    public String sayHello() throws java.rmi.RemoteException{
          return dao.sayHello();
class User{
   //MyDAO dao = new MyDAO();
   //OR
   RemoteDAO dao = new RemoteDAO();
   public void callDAO(){
          try{
          System.out.println( dao.sayHello() );
          catch( Exception e ){
}

>
That's only a good idea if the semantics of sayHello
as defined in MyInterface suggest that a
RemoteException could occur. If not, then you're
designing the interface to suit the way the
implementing classes will be written, which smells.
:-)But in practice you can't make a call which can be handled either remotely or locally without, at some point, dealing with the RemoteException.
Therefore either RemoteException must be part of the interface or (an this is probably more satisfactory) you don't use the remote interface directly, but MyInterface is implemented by a wrapper class which deals with the exception.

BUG: LabVIEW 8.6 crashes when you save a class vi with the same name

I am running into an annoying crash. If you try to add a VI with the same name to an existing class, LabVIEW will notify you that you made an error. Once you hit OK, LabVIEW crashes. Obviously, the workaround is not to save any VI with the same name as an existing VI to your class.

I have attached a ZIP file with an example project. Open the project and open one of the VIs in Test Class. Choose File->Save As. Choose Copy->Open additional copy. Make sure the box for Add copy to Test Class.lvclass is checked.
Do NOT try to save the VI over top of the existing VI. Go to a new folder and save the VI without changing the name. LabVIEW will save the VI, then inidcate it cannot add the file due to a naming conflict. Once you hit OK, LabVIEW may or may not hang for a few seconds, then crash.
When LabVIEW restarts, it does not indicate anything happened. It just comes up with the standard startup screen.
I stumbled across this attempting to create a copy of an existing VI, but forgetting to change the name.
I confirmed this does not happen in LabVIEW 8.5.1, so the behavior is new to 8.6.

Multiple ResourceBundle definitions with the same name

I created a new web application project with JSF support using Netbeans 5.5Beta. The new project has a simple welcomeJSF page that I did not modify. The only modifications I did is adding a CustomMessages.properties file under com.mywebsite.resourcs and adding the following entry to faces-config.xml:
<application>
        <resource-bundle>
            <base-name>com.mywebsite.resources.CustomMessages</base-name>
            <var>BundleOne</var>
        </resource-bundle>
        <locale-config>
            <default-locale>en</default-locale>
        </locale-config>
    </application>Now when I right click welcomeJSF and select Run File, the follow error is added to the log file of SJSAS PE9:

Go ahead and doubt if it makes you feel superior.
For others:
If your pom has this:
<dependency>

               <version>${jsf.version}</version>

Two AM's with the same name but different forms causes Deployment problems

Two Masters forms, DOC & PM are cloned except for the "where clause" in the View's query and the titles in their JSP's.
DOC workspace has a BC project and a BC4JSP Project. The BC project comprises of the EO and VO named ComVsStaticValue. In the Edit prop-> query for the VO I have specified the "where clause" as VSSV_VS_CODE='DOCTOR'.
In Java Webserver :-
The JSP's are located in C:\source\Doctor\ .. and the *.xml and *.class files generated by the BC proj is in C:\source\Doctor\pol_ValueSet\..
If I execute Doctor in JWS the records are getting filtered properly.
PM workspace has a BC project and a BC4JSP Project. Again The BC project comprises of the EO and VO named ComVsStaticValue. In the Edit prop-> query for the VO I have specified the "where clause" as VSSV_VS_CODE='PAY_MODE'.
In Java Webserver :-
The JSP's are located in C:\source\PMode\ .. and the *.xml and *.class files generated by the BC proj is in C:\source\PMode\pol_ValueSet\..
If I execute PM in JWS, the PM's JSP comes (the title is correct) but the records pertaining to DOC appears. I checked the View's xml file in C:\source\PMode\pol_ValueSet\ the "where clause" is correct. The xml & classes have the same name but their contents are different.
I want to know whether this problem is because both have the same name for the AM and the BC4JSP's property file.
Please clarify.

Deploying two app modules with the same name will definitely cause problems.
The JSPs use the information in the properties file to connect to the application module and get the data they need from the appropriate View Objects in those app modules. If you have two app modules with the same name, when a JSP tries to connect, it has no way of knowing which one of the app modules to connect to if they both have the same name.
You could:
1. Just use one application module that contains all the View Objects you need to access.
or
2. Rename one of the application modules or the package it is located in so the names are distinct. If you choose this method, you will also need to update the JSPs (specifically the 'registerApplicationFrompPopertyFile' method call), and your JSP project's appmodule property file.

Two groups with the same name in File and LDAP realms

Hi,
I configured WLS 6.0 SP1 to use an LDAP caching realm
as default one. In the LDAP server (Netscape Directory)
I have a group called Administrators. There is a group
with the same name in WLS own File Realm. When I click
on the Groups menu item in the administration console
I only get the Administrators group from the File Realm
listed. Is that expected? What will happen if I protect
a resource ti the Administrators group? Which one will
prevail - the one from the LDAP or the one from File
Realm? Or maybe the two will be merged?

Hi
First of all I want to know that where you created your class, In SE24 or in any programm.
if in SE24, then go to se24 open that class go to methods tab and check if that method name accurs at two places, if not, then
click on that method and check the code.
or if in a program.
then you must have defined like
class <class name> definition.
public section
method <method name>
endclass.
class <class name> implementation.
method <method name>
code for that method.
endclass.
It might be possible you have set the implementation part twice for that particular method, So please check and delete one implementation for that method.
Thanks

Can I create a lot of instance with the same name?

I have, for a project in my studies, to create a map for an adventure game. I must create monsters on this map. For this I use a class that I called Creature. In my class Map i have to initialise the monsters but I
choose their quantity with Math.random() so I don't know how much the map will contain. If in a loop I do: Creature monster = new Creature(); will I have different instances with the same name(I doubt)? Will I have one monster re-created in each iteration of the loop? How can I do to have different monsters in different places (my map is a matrix 2x2)?

You would have many Creature references made, but only one variable to hold them, and it would go out of scope outside your loop. You could create a Creature array or use a List (both defined outside your loop) - as
// array
int numCreatures = randomGeneratedCreatureQuantity();
Creature[] monsters = new Creature[numCreatures];
for (int j = 0; j < numCreatures; j++) {
monsters[j] = new Creature();
// Or a list
int numCreatures = randomGeneratedCreatureQuantity();
ArrayList monsters = new ArrayList();
for (int j = 0; j < numCreatures; j++) {
monsters.add(new Creature());
}Good luck

Applet with 2 methods with the same name in ie

Hi,
I have a problem with the Java 1.5 plugin for Internet Explorer .
When my Applet contains 2 methods with the same name but not the same return type, ie does not take the good return type.
Here is an exemple :
* Class TestApplet
package test.applet;
import java.applet.Applet;
public class TestApplet extends Applet {
     public void init() {
          System.out.println("init()");
     public void start() {
          System.out.println("start()");
     public String test(String s) {
          System.out.println("test(String) :" + s);
          return s;
     public boolean test(int i) {
          System.out.println("test(int) :" + i);
          return true;
}I have 2 methods test(), one returns a String and the other a boolean.
I use the following html code :
<html>
<head>
<script>
function test() {
     alert(document.DataAccess.test("hello"));
</script>
</head>
<body>
<applet WIDTH="500" HEIGHT="200" ID="DataAccess" NAME="DataAccess" CODE="test.applet.TestApplet">
</applet>
<div onclick="test()">test</div>
</body>
</html>
When I click on "test", the alert show "true" instead of "hello".
The problem only occurs with a JVM 1.5. It work fine with JVM 1.4.
Any idea ? Is it a bug ?
Thanks.

In your javascript method:
function test() {
alert(new String(document.DataAccess.test("hello")));
MSJVM and SUN jre use different conversion from javaScript objects to Java.
if you call from javaScript:
document.getElementById("myApplet").myMethod(22);
The method in MSJVM should look like this:
public whatever myMethod(Double d);
and SUN jre:
public whatever myMethod(Integer i);
The best thing to do is this:
public whatever myMethod(Object o);
               int col = 0;
               if (o.getClass().getName().toLowerCase().indexOf("integer") != -1) {
                    col = ((Integer) o).intValue();
               } else {
                    col = ((Double) o).intValue();
               }

Having multiple nodes with the same name in JTree!!!???

Hi!
I want to be able to have folders or files with the same name in different locations in my JTree. But if I do so the last one always overwrites the previous one.
I have a vector with strings like root\aaa\bbb\ccc\ddd.doc, root\aaa\bbb\eee.doc, root\aaa\ccc\fff.doc etc. In this case ccc\ddd.doc out of the first string would disapear.
In this post you can see how I add the nodes:
http://forum.java.sun.com/thread.jsp?forum=31&thread=54920
Is this because it adds everything in the same level or what? A solution/workaround would be much appreciated.

Bean property and public field found with the same name: getid

Hi all,
I have a ejb jar file contains some local entity beans and one session bean
, the session bean has some functions suck as findXXXByQuery() , InsertXXX()
, and I have created some model class for the entity bean , and use it as
the parameter or return type of the session bean , then I want to transfer
the session bean as a webservice , using ant automaticly . All this function
successfully in weblogic 6.1 , but when I want to run ant command in
weblogic 7.0 , an error occured :

Yes , I have a getid field in table , a getid in entity bean , and a getid

to test my jar file ? I send all files as attachments .
Any advice will be appreciate .

-=-=-=-=-=-For better or worse the JAX-RPC spec requires this behavior. From
section 5.4.1:
"There is no standard mapping for the case when a JavaBean property
has the same name as a public field. A Java to XML mapping
implementation is required to flag this case as an error."
Since you are not the first person to run into this restriction I'm
beginning to think we need an option to bypass it.

Create a dir if there exists a file with the same name

Hi..
I want to create a directory with file.mkdir(). But I recognize a problem when there is allready a File with the same name.
Is there any solution to handle a dir and a file with the same name?
eg: Dir "C:\Windows" and File "C:\Windows"
wami

This explains it... use "java Test2 asdsfd" for example. While this example doesn't show it,
if you try to create a dir with another slash on it c:\blah\ , it still can't be done.
import java.io.*;
public class Test2
public static void main (String args[]) throws Exception
     if (args.length < 1){
     System.out.println("Test2 [name]");
     System.out.println("creating bogus file " +args[0]);
     FileOutputStream fo = new FileOutputStream(args[0]);
     fo.write(55);
     fo.write(55);
     fo.write(55);
     fo.close();
     File x = new File(args[0]);
     if (x.mkdir()) System.out.println("made dir " + args[0]);
     else System.out.println("failed to make dir " + args[0]);
     System.out.println("deleting file " + args[0]);
     x.delete();
     if (x.mkdir()) System.out.println("made dir " + args[0]);
     else System.out.println("failed to make dir " + args[0] + " again !");
}

Problem with viewing 2 albums with the same name in Cover flow

Hi if I have 2 albums with the same name ("The Best of" for example) but of 2 different artists there's a big problem with all idevices like iPhone...
So when I go in iPod app and I want to watch all albums in cover flow when I choose one of these 2 albums I'll find all the songs of both albums merged...

The MouseListener you use would have to know about both JPanels and both their repaint-methods when mouseClicked-method is called.
Something like this:
public class Repainter extends MouseAdapter {
private JPanel panel1;
private JPanel panel2;
public Repainter( JPanel panel1, JPanel panel2 ) {
this.panel1 = panel1;
this.panel2 = panel2;
public void mouseClicked( MouseEvent me ) {
panel1.repaint();
panel2.repaint();
Tell me if I misunderstood the question or if you have any further qestions.

How can I merge folder with the same name so that the content does not replace the other

How can I merge folder with the same name so that the content does not replace the other?

That's only a good idea if the semantics of sayHello
as defined in MyInterface suggest that a
RemoteException could occur. If not, then you're
designing the interface to suit the way the
implementing classes will be written, which smells.
:-)But in practice you can't make a call which can be handled either remotely or locally without, at some point, dealing with the RemoteException.
Therefore either RemoteException must be part of the interface or (an this is probably more satisfactory) you don't use the remote interface directly, but MyInterface is implemented by a wrapper class which deals with the exception.

Use two VIs with the same name, different functionality on a single Project

Hi, I'm working with vision builder al labview, I need to integrate the vision builder migration Vis into my main program, (Is not an option), but I have multiple Vis autogenerated with the same name, how can i integrate them in the same project without dependency problems
Thanks in advance

Hi,
Unless you really need tight integration between the Vision code and the rest of your LabVIEW application, or would rather not have to pay for a Vision Builder AI runtime license on the targets on which you want to deploy your final application, I would recommend you look into using the Vision Builder AI LabVIEW API instead of migrating the inspection to LabVIEW.
The API allows to control Vision Builder AI by launching a Vision Builder AI engine, running the inspection and retrieving resulting images and results.
The advantage of the API is that it allows for easier modification and debugging of the Vision Inspection that you designed in Vision Builder, if you need to make changes later. (i.e. all you need to do is open the inspection in Vision Builder AI, modify parameters, add steps etc).
You won't have to change your LabVIEW application, unless you want to output additional results.
When you build and deploy your application, you will need to install Vision Builder AI on the target machine and get a runtime license for it.
Migrating the inspection to LabVIEW is a one way deal. If you need to make changes to the inspection, you will have to migrate the inspection again, or modify the code outside of the Vision Builder AI environment.
As you might have noticed, the code generated is quite complex, and it is recommended to go this route only if you need really tight integration/synchronization between the vision code and the rest or your LabVIEW code, or if you would rather pay for a cheaper Vision runtime license rather than a VBAI runtime license for the deployment machine (in case of deploying multiple systems where cost is a big consideration).
Vision Builder AI API examples are located in this folder:
C:\Program Files (x86)\National Instruments\Vision Builder AI\API Examples\LabVIEW Examples
Hope this helps clarify the use cases and help you make the right decision for your design.
Best regards,
Christophe
