Urgent : Communicate from JAVA Applet to Oracle Forms

Hi All,
I have developed swing applet. Through this applet I need to start the Oracle Forms on web and access it as well. Is there a way to to this. In this case, Oracle Form is using Global Variables, and the requirement is to set these from my swing applet.

Many thnx Frank.
Still little confused. I am J2EE guys and hardly have any understanding on Oracle Forms. I am explaining the requirement in detail so as to you can get an insight into my issue.
We have a developed a swing Applet, which would be access on web. We have received Oracle Forms from the client, and this has been installed on Oracle10gAS. Our application is installed on the same server. Once user starts interactions with the applet, it will be session based. Also the applet is running at the client end and the form would open at the client end as well. So how is this singleton going to benefit it.
If the singleton in placed at the server end, how would be maintain the session?
Can the solution you are mentioning, used in some way to implement SSO, although the login will be done through the applet?
I am sorry to be a trouble, but if can possibly provide some code snippet, it would be of immense help.
Thnx a million!
Regards,
Rajiv

Hi Grant
Thanks...I developed an applet which has a button on it and clicking the button something will happen. I mean this is a complete java project. Now I need to use this java applet from Oracle Form...that means I'll develop an oracle form on which the applet will be embedded so that the button on the applet can be pressed. Now could you please help me do this? I also have another problem but I need to resolve this first.

How to use Java Script in Oracle Forms 10g

Hello,
Appreciate if anyone could help me using Java Script in Oracle Forms 10g?
Thanks
GM

Thank you for your reply. I was reading on the metalink that we could use the to call the java script from oracle Forms 10g (Doc ID 265863.1)
Example:
WEB.SHOW_DOCUMENT ('javascript:void(window.open("http://www.oracle.com","","location=no,toolbar=no,menubar=no,status=no,"));self.close()','_blank');
I tried it but it did not open the any window as it claims. Am I missing anything? Is there any IE related setting which I need to modify for the above to work?

Java.lang.NoSuchMethodError: oracle.forms.handler.IHandler.getApplet()Ljava

Hello to all
I hope it is right forum for my question
I have found for error I get in Directprint this following:
When you migrate to the latest Forms version (10.1.2.3 or 11) and try using a JavaBean created with an older Forms version, you can get the following error, at runtime, in the Java Console:
Exception in thread "thread applet-oracle.forms.engine.Main-1" java.lang.NoSuchMethodError: oracle.forms.handler.IHandler.getApplet()Ljava/applet/Applet
The reason is you try to use a Java Bean compiled with an older Forms JAR file, like f90all.jar.
So, to correct the issue, you have to change the Java code then re-create the JAR file:
private Main formsMain = null;
Replace:
formsMain = (Main) handler.getApplet();
by:
// getting the Forms Main class
try{
Method method = handler.getClass()
.getMethod("getApplet", new Class[0]);
Object applet = method.invoke(handler, new Object[0]);
if (applet instanceof Main) {
formsMain = (Main)applet;
}catch(Exception ex) {;}
Then create and deploy the new JAR file to your /forms/Java folder.
My problem is
But I am very poor in java code, could you guide me to do what that article said, or pointing me where find instruction how do this following

Java class in oracle forms

Hello experts,
I am new in oracle forms.I am using oracle forms 11g with weblogic 10.3.5 at windows 7.Someone please clear me that the injection of java programing in oracle forms is through BEANS item only or I can use it(java class) as a part of my oracle forms.I mean I have a Java class.Could I use this java class inside my oracle forms without using Beans Item.
Thank You
regards
aaaditya

In forms you can use java in two different ways
1. On the client-side. Using java-beans you can extend the client-functionality of forms. The code will run on the client-computer in the context of the applet.
2. On the server-side. Using the java-importer you can build a PL/SQL-wrapper around a java-class and so use the java-code in your forms-PL/SQL
What is your reuqirement?

Help : Unable to use Java Beans in Oracle forms 6i

Hi ,
I have been trying to run few sample code to understand how to use Java beans in oracle forms 6i .But have been largely unsuccessfull.
It will be great if somebody can provide me with some simple form( and java code )which uses java beans concept to give some data to the java program and receive some data from it . Pls inform me about the settings that need to be done.
If you guys know it then pls take the pains of writing a simple form and java code.
i hope somebody will respond because your reply is very necesary for me to proceed.
U can email me the code > [email protected]
Thanks in advance.

Thanks for your reply Francois.
Actually i am not facing problem understanding the programming technique.
I think the problem at my end is more of a cofiguration one.I am using forms version 6i
on oracle 8.
Every time i set the imlementation class property of the bean area it gives an error 13010 which translates to that "the class being mentioned is not extending the IView class".
The class i have written extends VBean so i am not sure why this error is occuring.
I think if oracle (correctly) finds the java class to use then i will be able to proceed.
Pls reply.
If you have some code that is working fine then pls send it to me.And also inform is some environment variables have to be set for its use.

Error while importing java class into oracle forms 10g

Hi
I have generated a web service client using jdeveloper 10g. It consists of complex type methods. I am trying to import the class files using java importer in oracle form 10g. I am able import all of them successfully except one. That one is the main method. Please see the error and suggest me how to overcome this error.
Exception occurred: java.lang.NoClassDefFoundError: oracle/jdeveloper/webservices/runtime/WrappedDocLiteralStub
Thanks in advance

Do you see oracle/jdeveloper listed in "Import Java Classes" when you try to import?
If not, make sure you add C:\DevSuiteHome_1\jdev\lib\jdev.jar to FORMS_BUILDER_CLASSPATH in registry
Also excetion indicates: oracle/jdeveloper/webservices/runtime/WrappedDocLiteralStub

Problem of calling the applet by Oracle Form

Hi,
The oracle form invokes a applet function, and send one parameter to the applet. The parameter will be displayed in the applet correctly at the first time.
But if the user do not close the applet and use invoke the applet function again, the applet cannot show the latest parameter and keep show the old one.
Please give me some adive.

Hi,
This is a JDeveloper help forum, the Formsforum can be found at Forms Now you might think that Forms developers don't understand Java well enough, they do however understand teh Forms context and this is important to answr the question.
a) Which Java version does your ben require?
b) Are you using JInitiator or JavaPlugin (Jinitiator only supports Java 1.3)
c) Is your PJC signed? Note that running an app stand alone as a Java app does not require special grants. Running it within a JavaApplet - as Forms is - does execute teh bean in a security sandbox, for which reasons the jar file must be signed and the public key be available in the Forms certdb.txt file (assuming Jinitiator)
d) An exception stack trace gives more information than "Oracle Form it doesn't run and exception is thrown on javax.imageio and other packages", which is meanlingless to me and others. Teh stack trace canbe copied from teh JInitiator console
I recommend resending this question to the Forms forum

Calling a WebService from Java Applet

Hi all,
In my application I have 3 projects:
1. server - for all the business logic.
2. view - for web app.
3. swing - for applet.
In the view project I wrote a WS, and I want to call it from my applet. So I created a WS using the Jdev (10.1.3.2) wizard in the view project (I tested it and it worked fine), and in the swing project I created a proxy for this WS, tested it and it worked fine. Then I created a JAR containing the swing project with the WS proxy classes, opened the Applet and find out that I have some classes missing, so I started adding all the relevant Jars and ended with a ~13MB JAR containing all the swing project jars that in the class path for a simple Applet.
I know that I'm missing something but I dont know what. Do I really need all those Jars. Is there a simple way to call to a WS via Applet?
This is the list of all the Jars:
activation.jar
commons-logging-api.jar
commons-logging.jar
ejb.jar
http_client.jar
jaxb-api.jar
jaxb-impl.jar
jaxen.jar

Try this:
1. open the webService data controll in the Data Controls section and drag the method from the webService onto the method call activity in your task flow. This will overwrite the current method property (the one which pints to your bean, make a copy of this entry if you can't reproduce it by hand). This too will create an entry in the pageDef of the method call activity.
2. reenter (or paste) the original value in the method property, so that it again points to your bean. The entry in the pageDef will remain!
3. now in the bean method you can access the method via its binding like you access any other method from the binding:
// GET A METHOD FROM PAGEDEF AND EXECUTE IT
// get the binding container
BindingContainer bindings = BindingContext.getCurrent().getCurrentBindingsEntry();
// get an Action or MethodAction
OperationBinding method = bindings.getOperationBinding("YourMethodActionNAME");
if (method == null)
// handle method not found error...
// if there are parameters to set...
Map paramsMap = method.getParamsMap();
paramsMap.put("param","value") ;
// execute the method
method.execute();
List errors = method.getErrors();
if (!errors.isEmpty())
   // handle errors here errors is a list of exceptions!
// no error resume normal workTimo

How to use java programe in oracle form

Hello Expert,
My Config is : -
Forms [32 Bit] Version 11.1.1.3.0 (Production)
Jdeveloper - 10.1.3
I want to use the java programe in form builder. I create the one java class in Jdeveloper -
package demo;
import java.net.InetAddress;
import java.net.NetworkInterface;
import java.net.SocketException;
import java.net.UnknownHostException;
public class get_info{
   public static void main(String[] args){
   ch_add();
   public static void ch_add()
InetAddress ip;
try {
ip = InetAddress.getLocalHost();
/*System.out.println("Current IP address : " + ip.getHostAddress()); */
NetworkInterface network = NetworkInterface.getByInetAddress(ip);
byte[] mac = network.getHardwareAddress();
/*System.out.print("Current MAC address : ");   */
StringBuilder sb = new StringBuilder();
for (int i = 0; i < mac.length; i++)
sb.append(String.format("%02X%s", mac[i], (i < mac.length - 1) ? "-" : ""));
System.out.println(sb.toString());
} catch (UnknownHostException e) {
e.printStackTrace();
} catch (SocketException e){
e.printStackTrace();
and this into Formweb.cfg and default.env and also add into Form_class_path. After that i import this java into forms.

I read both document which is given by you.
Basicaly i don't know how to call java program in form builder.
I wrote this code on When-button-pressed
DECLARE
jo ora_java.jobject;
rv varchar2(1500);
ex ora_java.jobject;
BEGIN
jo := get_info.new;
rv:=get_info.ch_add(jo );
EXCEPTION
WHEN ORA_JAVA.JAVA_ERROR then
message (' Unable to call out to Java, ' ||ORA_JAVA.LAST_ERROR );
message('');
WHEN ORA_JAVA.EXCEPTION_THROWN then
ex := ORA_JAVA.LAST_EXCEPTION;
message(' Unable to call out to Java ' ||Exception_.toString (ex ) );
message(' Unable to call out to Java ' ||Exception_.toString (ex ) );
END;
No error comes and no output comes. I want the client MAC ID. please guide me where i need to change the code.

Import Java Classes - How manipulate Java List in Oracle Form

Good afternoon,
I call a Web Service from Oracle Application Server 10g Forms Services but the object returned by the method is a java list. I created a stub/skeleton with JDeveloper and the communication between WebService and Oracle form works fine. The problem is how to desencapsulate the list within ORA_JAVA. I imported java.util.List it does not solve my problem.
Method called: public List DecryptToken(Context context, String token) throws Exception
This list will have in List.get(0) -> Context object
List.get(1) -> String
List get(2) -> String
List get(3) -> Param []
Thanks for your help.
best regards,
TT
