How register COM object from java?

Hi!
In my user home directory I have myCOM.dll. My sign applet use this myCOM.dll. But before use this dll I must register it (by use regsvr32).When myCOM.dll will be success register my applet can work. The problem is that I can not get answer from regsvr3 (is myCOM.dll are successed registered or not, or is user has a grants to register COM object and so on.)
Again, my java applet can work ONLY when myCOM.dll is registered.
How I can register myCOM.dll from java applet and if registered is not success exit from java applet?

I must not have been clear. I am not asking how to access a COM object using Java, we already have tools to do that.
The question is whether there is a way to define a COM interface using Java. I want to code my COM object in Java. Right now we are using PowerBuilder to code COM objects. I would rather use Java.

How to pass Objects from Java App to JavaFX Application

Hello,
New to the JavaFX. I have a Java Swing Application. I am trying to use the TreeViewer in JavaFX since it seems to be a bit better to use and less confusing.
Any help is appreciated.
Thanks
I have my Java app calling my treeviewer JavaFX as
-- Java Application --
public class EPMFrame extends JFrame {
Customer _custObj
private void categoryAction(ActionEvent e)   // method called by Toolbar
        ocsCategoryViewer ocsFX;    //javaFX treeviewer
        ocsFX = new ocsCategoryViewer();    // need to pass in the Customer Object to this Not seeing how to do it.
                                              // tried ocsFX = new ocsCategoryViewer(_custObj) ;    nothing happened even when set this as a string with a value
public class ocsCategoryViewer extends Application {
String _customer;
@Override
    public void start(Stage primaryStage) {
     TreeView <String> ocsTree;
     TreeItem <String> root , subcat;
TreeItem <String> root = new TreeItem <String> ("/");
        root.setExpanded(true);
         ocsTree = new TreeView <String> (root);
         buildTree();     // this uses the Customer Object.
        StackPane stkp_root = new StackPane();
        stkp_root.getChildren().add(btn);
        stkp_root.getChildren().add(ocsTree);
        Scene scene = new Scene(stkp_root, 300, 250);
        primaryStage.setTitle("Tree Category Viewer");
        primaryStage.setScene(scene);
        primaryStage.show();
    public static void main(String[] args) {
        _customer = args[0];      // temporarily trying to pass in string.
        launch(args);

JavaFX and Swing integration is documented by Oracle - make sure you understand that before doing further development.
What are you really trying to do? The answer to your question depends on the approach you are taking (which I can't really work out from your question). You will be doing one of:
1. Run your Swing application and your JavaFX application as different processes and communicate between them.
This is the case if you have both a Swing application with a main which you launch (e.g. java MySwingApp) and JavaFX application which extends application which you launch independently (e.g. java MyJavaFXApp).
You will need to do something like open a client/server network socket between the applications and send the data between them.
2. Run a Swing application with embedded JavaFX components.
So you just run java MySwingApp.
You use a JFXPanel, which is "a component to embed JavaFX content into Swing applications."
3. Run a Java application with embedded Swing components.
So you just run java MyJavaFXApp.
You use a SwingNode, which is "used to embed a Swing content into a JavaFX application".
My recommendation is:
a. Don't use approach number one and have separate apps written in Swing and Java - that would be pretty complicated and unwarranted for almost all applications.
b. Don't mix the two toolkits unless you really need to. An example of a real need is that you have a huge swing app based upon the NetBeans platform and you want to embed a couple of JavaFX graphs in there. But if your application is only pretty small (e.g., it took less than a month to write), just choose one toolkit or the other and implement your application entirely in that toolkit. If your entire application is in Swing and you are just using JavaFX because you think its TreeView is easier to program, don't do that; either learn how to use Swing's tree control and use that or rewrite your entire application in JavaFX. Reasons for my suggestion are listed here: JavaFX Tip 9: Do Not Mix Swing / JavaFX
c. If you do need to mix the two toolkits, the answer of which approach to use will be obvious. If you have a huge Swing app and want to embed one or two JavaFX components in it, then use JFXPanel. If you have a huge JavaFX app and want to embed one or two Swing components in it, use a SwingNode. Once you do start mixing the two toolkits be very careful about thread processing, which you are almost certain screw up at least during development, no matter how an experienced a developer you are. Also sharing the data between the Swing and JavaFX components will be trivial as you are now running everything in the same application within the virtual machine and it is all just Java so you can just pass data around as parameters to constructors and method calls, the same way you usually do in a Java program, you can even use static classes and data references to share data but usually a dependency injection framework is better if you are going to do that - personally I'd just stick to simply passing data through method calls.

How can I call a COM object from a PL/SQL CODE

Hi everyone,
Does anyone know how to call a COM object from a stored procedure in oracle.
a sample of code
please help,
Hilaire

Are you familiar with external procedures? Basically, you can expose functions exported by a shared library (i.e. a DLL on Windows) to the Oracle database. My assumption is that you'd probably need to write a wrapper DLL around the COM object, since I believe you can only pass fundamental data types back and forth (i.e. no object references). You'd expose the method(s) of that wrapper DLL to the database via external procedures.

Instantiating COM objects from within the java code in WLS

is there a way to use COM objects from servlets or ejb's,

Sun has released a beta product - its a COM bridge that you can use
to connect a Java2 JVM to a COM object with. I havent tried it yet
but I probably will soon.

No, at the current time we only support COM integration when using the

Nwdi-managed access of pcd-objects from java web dynpro

Hi,
im am trying to access portal pcd-objects from a java web dynpro component (namely getting and setting personalized iview properties). for locally managed web dynpro components this works fine with the code below.
when i try the same with a nwdi managed web dynpro component i run into problems regarding references to used dcs. for instance, i need to reference used dc SAP_JTECHS/tc/epbc/pcm/adminapi/java because the build needs tcepbcpcmadminapijava.jar which is inside the mentioned dc. but access permissions of this dc don't allow the dependency. when i try to "add used dc ..." in nwds i get the error message: illegal dependency: access list does not allow use of ...
has someone any solution for this problem? are there other ways of accessing pcd-objects from java web dynpro (nwdi managed!)?
thanks

Hi Kust,
To access the PCD objects the code you used looks ok for me but your main issues is related to the dc access permissions. This thread discussed about the similar issue. Please review this below thread.

Invoking COM objects from Weblogic EJB

Hi,
I am searching the BEA site on how best to call COM objects from
a EJB deployed in Weblogic. I find rmi over iiop, articles on ObjectBridge
which are confusing. Is there a sample where a COM method is called
from EJB server ( I only see example the other way round)
Thanks,
Harish.

http://www.weblogic.com/docs51/examples/com/examples.com.ServerSideDLLClient.html
This shows use the WebLogic COM compiler to generate and RMI wrapper
around a COM DLL and invoking it remotely. Unfortunately, the example
appears to be a little out-of-date (e.g., it is using the old RMI Naming
style of doing the lookup)...
Be forewarned, WebLogic COM is not supported in WebLogic 6.0 (due to the
inavailability of a Microsoft 1.3 JVM implementation).

JIntegra is fine, but I want to know if anybody tried WebLogic-COM.

Actually I tried out the 'beeper' sample but still have many doubts.

Returning objects from Java stored procedures

I need to pass an object from Java to a Java SP which updates the object and returns the object back. The Java SP will be calling a PL/SQL procedure which returns some nested tables that I want to stick into the passed object.
I tried using "IN OUT" for the object in the call spec but got an error that it was not "appropriate for the parameter". So, the next option seems to be to pass it in and then return it from the Java SP. I'm just wondering though what the the best approach for accomplishing this? I've looked through some of the sample code on the OTN but haven't found anything yet that really helps.

I am trying to use custom object classes. I have setup a type map for the connection and my custom class implements SQLData. Yet, when my client tries to call the Java SP, it gets ORA-00932 complaining of inconsistent data types (expected IN conversion failed).
I turned on some debug info (i.e. oracle.jdbc.sql=true) but it didn't provide any useful info in regards to why I'm getting this error. Unfortunately, the JDBC Developer's Guide does not provide full examples of the code.

Calling inactive version of ABAP object from Java

Hello,
When I call an ABAP object from Java Program which version of ABAP object is called inactive or active ?
Is there a mechanism to call the current inactive version or any other previous inactive /active versions ?
Regards,
Tarun

Only the "active" version of ABAP code is active and runnable.
You cannot run inactive versions. Like you have to compile a .java file to a .class file o make it runnable in the JVM.

Cannot Acccess Applet Object from Java Script

Hi,
I am using jRE1.5, and Kava Chart Applets. Those applet jars are compiled in jdk 1.5 version. I have created one jsp where I used ,<applet> tag. The problem is when ever I am going to access the applet object from java script it is not returning the actual java applet object, when put an alert message it shows [object]. So i am not able to access the methods or the applet class.and also the screen gets hung, nothing is coming.It get stuck at the point where i tried to access the applet method like document.getElementById(applet_id).<<<some method of the applet class>>.Also it is not showing any kind of javascript error or Applet class exceptions.
But the strange thing is, when i use jdk 1.6, the page is running fine.Also when i try to print the applet object from javascript it is showing the proper class name.
Please help me solving the problem.

A number of changes and improvements were made between 1.5 and 1.6 - the entire plugin is new. You need to change to 1.6, as 1.5 goes EOL about November this year and future changes to this area in 1.5 are unlikely.

How to get stylesheet object from JAVA RESOURCE stored in DB

Hi,
I stored a xslt file in the database and have a JAVA RESOURCE file now. How can i get a stylesheet object from this resource file?
I took the following class to get an impression how to get the contents of the resource but -although the name of the resource was spelled correctly- i got a file not found exception.
Whats wrong?
public class PrintRessource {
public static void print (String p_ressource){
try {
Class c = PrintRessource.class;
System.out.println(c.toString());
InputStream file = c.getResourceAsStream(p_ressource);
if (file == null)
throw new FileNotFoundException("XSLT file not in DB");
byte[] buffer = new byte[4096];
int bytes_read;
while ((bytes_read = file.read(buffer)) != -1)
System.out.println(new String(buffer, 0 , buffer.length));
catch (Exception exp) {
System.out.println(exp);
Thanks

The code works as is. I just forgot to add the slash in front of the Resource file name.
