Fbean

Hi,
I was trying to develop a form, which looks like a web page with urls to other forms. I tried using fbean (using hyperlink), I am able to generate the page but I want to get URLs from the table.
e.g. table t_urls (seq_no, label, url)
=====
I tried writing ...in when-new-form-instance
FBean.Register_Bean(hHyperlink,v_menu.seq_no,'oracle.forms.demos.beans.Hyperlink');
FBean.Invoke(hHyperlink,v_menu.seq_no,'setURL',v_menu.url);
FBean.Invoke(hHyperlink,v_menu.seq_no,'setLabel',v_menu.label);
FBean.Enable_Event(hHyperlink,v_menu.seq_no,'actionListener',true);
=======
but getting error:
FRM-40735: WHEN-NEW-FORM-INSTANCE trigger raised unhandled exception ORA-03114
Please help...!
thanks

Cant get FBEAN.GET_CHAR_PROPERTY to return more than one character

I have a javabean on my form. I am passing values to the bean using FBEAN_INVOKE. I need to get error messages back from Java. I set the logging mode to Log_All.
I use FBEAN.GET_CHAR_PROPERTY to return an error.
Here's my code:
retval varchar2(10);
retval := FBEAN.GET_CHAR_PROPERTY('bean',1,'errorMessage');
message (retval);
The message appears on the Java control panel. But the message returned in the Form is null, unless the value is one char length. It should be able to return a string.
I have a similar problem when using FBEAN_INVOKE_CHAR.
My Java class extends JPanel
Does anyone know what is wrong ?

I dont know how but this issue resolved itself

FBean.Register(classname) only succeeds the first time classname is used?!

This is not a question, it is a futile cry of helplessness, such as a 9 month old might make when they strike their head on a rock.
Consider:
'BLOCKA'.WHEN-NEW-BLOCK-INSTANCE:
FBean.Register_Bean('ITEMA', ALL_ROWS, 'my.TestBean');'BLOCKB'.WHEN-NEW-BLOCK-INSTANCE:
FBean.Register_Bean('ITEMB', ALL_ROWS, 'my.TestBean');And what happens? If BLOCKA is 'first', ITEMA is populated with the TestBean, but BLOCKB's ITEMB is not. Conversely, if BLOCKB is first, ITEMB is populated with the TestBean, but BLOCKA's ITEMA is not.
Happily, it doesn't matter to me today. But it would be fair to say that Forms and I are becoming estranged on a fairly brief aquiantance.

Thanks Francois,
I am certainly feeling a bit alone in the Oracle Forms enhanced JavaBeans world, trying to get a PROPERTY_CHANGED_EVENT to bubble up from my bean into my form. [This Google Query|http://www.google.com.au/search?q=FBEAN+PROPERTY_CHANGED_EVENT&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-GB:official&client=firefox-a] for "FBEAN PROPERTY_CHANGED_EVENT" (both of which would appear on the FBEAN.ENABLE_EVENTS line) finds only my poor posts from yesterday.
I really, really dislike the legacy Forms JavaBeans approach. A JavaBean is all about properties and state. Something simple like 'background-color' is a good example. You should be able to simply:
FBEAN.SET_PROPERTY('My_Bean_Area', 'background-color', '#FFFFF');
which is equivalent to:
bean.backgroundColor = "#FFFFFF";
... and the same bean class is usable in both Java and Oracle Forms.
With the legacy Forms JavaBeans appraoch, you've got to write a wrapper class, AND you'd be forced to write something semantically nonsensical like:
:success = GET_CUSTOM_PROPERTY('My_Bean_Area', 'SETBACKGROUNDCOLOR', '#FFFFFF');
and the hapless monkey who's come to fix your broken code can't wrap his mind around why your'e using a getter to mutate the bean (or why you're returning a value from your setter, for that mattter).
(PS. I do not accuse YOU of such crimes, but i have inherited a codebase which would shock you. and the legacy Forms JavaBeans approach is largely to blame).
Anyhow. I guess I had better try to extract some sense from GET_CUSTOM_PROPERTY and friends instead of whining ...
cheers,
David.

Fbean doesn't work anymore after forms patch 10.1.2.2.0

Hi everybody!
I was working with Forms 10.1.2.0.2, Oracle AS 10g release 2 (10.1.2.0.2) and I
was using Internet Explorer 6.
There was a limitation with IE 6, so I choosed to migrate to Internet Explorer 7.
Now I have Internet Explorer 7, Oracle AS 10.1.2.2.0, Forms 10.1.2.2.0.
I recompiled all the frames and libraries.
All the frames containing a java bean reached the FRM-92101 error. I had to destroy and
recreate each javabean.
Now the frames reach the same error when calling Fbean package.
Do I have to recompile this package or something like that?
How can I do?
Has anybody got an idea?
Thanks for your help.

Hi Ramesh,
I applied latest patch 6673231 (MLR#11, 11-FEB-2008) but the issue persists. On metalink I found SR 18299248.6 and Note:469848.1 on this exact problem.
However the patch has been removed from the temporary ftp location given in the SR, and its not in the latest merge patch so I can't get my hands on it.
Could you please get me this patch, or do you recommend me to open a new SR just to get to download this patch? Many thanks!

Public method of javabean not executed when invoked with FBEAN.INVOKE_NUM

Hi,
i write a trivial javabean with public method named 'somme' that return int value and take no arguments.
i my PL/SQL trigger code, i register an instance of the bean and take a call to the public method 'somme' that return a int value that i display in display item of my form.
the java bean is well registered and i verified that the code in the constructor is well executed. But the call to the public methode dont work.
thank you for your help.

Hello,
it's a mistake for me. when i instanciate the javabean from another java classe in jdev, the execution is well and the process exited with code 0.
but when i instanciate it from pl/sql the problem occurs.
i commented all the lines of my code except the line that register the javabean
     FBean.Register_Bean(hBean, 1, 'amar.FbeanExemple');
and i have the same problem even though the code in the constructor is executed.
the error occurs after the code in the concstructor is executed.
i folllow all the information about this error:

How to use the FBean package?

I really haven't a clue what i am doing but using the online help i constructed the following code in my forms "when-new-form-instance" trigger. I then created a bean item in my control block called 'MyBeanArea'. I ran the form and nothing happened, the bean area remained blank. How do i get this thing to work?
Thanks

Forms 10.1.2 on XP (standalone)
-- Java Beans
FBean.Register_Bean('control.MyBeanArea', 1, 'sunw.demo.juggler.Juggler');
fBean.Set_Property('control.MyBeanArea',1,'animationRate',150);
FBEAN.INVOKE('control.MyBeanArea',1,'startJuggling');

Database 10g Express Edition on Win XP
Have downloaded Forms demo 10gr2 and have found that its not been updated and there appear to be lots of discrepancies in the install guide e.g.
The often referred to forms90 directory in the install notes is now called 'forms' in my installation I believe.
Modifying orion-web.xml as per installation notes means having to read between the lines e.g.
<classpath path="%ORACLE_HOME%/forms90/java/f90jdapi.jar" />
<classpath path="%ORACLE_HOME%\forms90\demos/metadatabrowser/classes" />
<virtual-directory virtual-path="/formsdemo" real-path="%ORACLE_HOME%\forms90\demos" />The first line is not a correct DOS path (Linux I assume) so this would not be valid would it? Also the 'forms90' directory is no longer valid, its 'Forms'.
Modifing the web.xml .....
<servlet>
<servlet-name>l90servlet</servlet-name>
<servlet-class>oracle.forms.servlet.ListenerServlet</servlet-class>
</servlet>had to replace l90servlet with lservlet (is this correct)
and a number of other similar incidences of this. Only half way through the guide and will finish off tomorrow. Following the install guide as best i can but am a little bit frustrated as i don't understand the changes i am making, ah well hey ho.
Funny thing is when i run the sample test in my browser which is a blue tick (tick.gif) I eventually got it to work by typing in the following
http://127.0.0.1:8889/forms/formsdemo/images/tick.gif[\code]
In the URL "/forms/formsdemo/images/tick.gif" is a directory path but i don't have a directiry called "formsdemo" so how come this seems to work???

Has anybody implemented FBEAN with dispatchCustomEvent?

Have successfully implemented a lot of Beans without custom event handling, now I need this. So I have defined following test.java:
import oracle.forms.handler.IHandler;
import oracle.forms.properties.ID;
import oracle.forms.ui.CustomEvent;
import oracle.forms.ui.VBean;
public class test extends VBean {
static final ID TESTEVENT = ID.registerProperty("TESTEVENT");
private IHandler vIHandler = getHandler();
public test() {
System.out.println("Bean test has been instantiated");
public void init(IHandler i_vIHandler) {
super.init(i_vIHandler);
vIHandler = i_vIHandler;
System.out.println("init: i_vIHandler>" + i_vIHandler + "<");
System.out.println("init: vIHandler>" + vIHandler + "<");
System.out.println("Method init has been invoked");
public void log() {
try {
System.out.println("log: vIHandler>" + vIHandler + "<");
System.out.println("Method log has been invoked");
CustomEvent vCustomEvent = new CustomEvent(vIHandler, TESTEVENT);
dispatchCustomEvent(vCustomEvent);
System.out.println("Event has been invoked");
} catch (Exception e) {
System.out.println("Exception>" + e.getMessage() + "<");
The problem is, when I call
Fbean.register_bean(hbean, 1, 'test');
then the constructor is called without calling init before. So if I later call:
Fbean.Invoke(hbean, 1, 'log');
I get an exception that argument vIHandler in call:
CustomEvent vCustomEvent = new CustomEvent(vIHandler, TESTEVENT);
is null. So the WHEN-CUSTOM-EVENT-Trigger is not raised.

Hello!
Sorry, I do not have a solution, but the same problem: everythin works OK with my beans. But when I try to implement custom events - init() is not called and getHandler() always returns null!

RR

FBean.Set_Property problem

I'm trying to set parameters on a applet in my Bean area.
In the html page for the applet the parameters are called in this way:
E.g.
document.viewONE.openFile("invoice.tif", 1);
And in my forms I try this:
FBean.register_bean('B1.BA1',1,'ji.applet.jiApplet');
FBean.Set_PropertyFBean.Set_Property('B1.BA1,1,'viewONE.openFile','"file://C:/Test/invoice.tif", 1');
Am I doing something wrong in the parameter call to the Applet from my form?

Very frustrating, I can see that the properties and methods are beeing invoked but it does not change in the loaded applet. Do I need to do some "refreash" of the loaded applet in the Bean Area after changing properties and invoking mehods. See java console output:
*** ji.applet.jiApplet Heavyweight bean ji.applet.jiApplet
*** ji.applet.jiApplet Applet bean ji.applet.jiApplet
*** ji.applet.jiApplet Setting pFileButtons to false
*** ji.applet.jiApplet Invoking setFileButtons

*** ji.applet.jiApplet Invoking setFileMenus
*** ji.applet.jiApplet Setting mIsFileButtons to 0
*** ji.applet.jiApplet Invoking isFileButtons
*** ji.applet.jiApplet Got mIsFileButtons = false
*** ji.applet.jiApplet Setting mOpenFile$1 to notfound.tif
*** ji.applet.jiApplet Setting mOpenFile$2 to 1
*** ji.applet.jiApplet Setting mOpenFile to 0
*** ji.applet.jiApplet Invoking openFile

FBean.register_bean Problems!

I have made my own bean class that I want to use in a BeanArea. But I get this error when I run the form.
*** VBean Setting beanName to lib.getPath
*** VBean Failed to instantiate class: lib.getPath java.lang.ClassCastException: lib.getPath
In the form I try to register the bean in this way.
FBean.register_bean('B1.BA1',1,'lib.getPath');
I have included the jar file with my bean in formsweb.cfg
archive_jini=f90all_jinit.jar,util.jar
Any idees what's wrong?

I extended BeanWrapper in my bean class that did the trick.

Introspection Failed when using FBean.Register_Bean() and JInitiator

I am posting this for the benefit of others who might run into it when using the 'enhanced JavaBeans support' in Forms 9i. Under certain circumstances, an FBean.Register_Bean() might silently fail.
Those circumstances include:
<li> the JavaBean you are attempting to register extends {font:Courier}javax.swing.JPanel{font}
<li> the runtime environment is JInitiator Version 1.3.1.9
Whether this is affecting you or not can be determined by using FBean.Set_Logging_Mode('MyBeanArea',1,FBean.LOG_ALL) as described in the help topic {font:Courier}How to Add JavaBeans using Enhanced JavaBeans Support -> Working In Debugging Mode{font}. If you do this, you might get output like the following in JInitator's console.
Failed to introspect class: class package.TestBean java.lang.NullPointerException
for example:
Forms Applet version is : 90290
*** VBean null PropertyManager for id = FOREGROUND
*** VBean Got FOREGROUND = null
*** VBean null PropertyManager for id = BACKGROUND
*** VBean Got BACKGROUND = null
*** VBean null PropertyManager for id = FOREGROUND

Fbean invoke method (nested)

ias904sp1
I havn't seen any examples on this and I'm not sure of the syntax, this doesn't invoke the method requested
:block3.item15 := fbean.invoke_num('block3.bean_area4',1,'GetHMTLPane().GetDocument().GetLength()');
Same without the brackets
:block3.item15 := fbean.invoke_num('block3.bean_area4',1,'GetHMTLPane.GetDocument.GetLength');
Javaconsole shows when methods are successfully invoked - but its is blank for this call
Whats the correct syntax?
Thanks

Help on FBean

Hi,
Can some one help me on FBean. I'm trying to use FBean.Invoke to invoke the constructor which takes an item number as an argument and displays an image on the bean area of the form. If I hardcode the item number and use the implementation class property and specify the class name there the image comes up fine. But if I try to invoke with the FBean invoke method by passing the method name(which is constructor here), and the item number then it does not bring any image on the bean area of the form. So, can any one tell me how to use the fbean.invoke.
Thanks in advance.

Duncan,
Thanks for replying.
The reason I am trying to use FBean is that in a previous post Frank Nimphius mentioned that I should try FBean to get around a clipping problem I was having. This fixed the clipping problem, but in Forms 6 I was using VBean for communications which no longer works, I am now trying to replicate JavaBean/Form communications without using VBean with FBean.
I have now got a sample bit of code which extends Canvas with nothing visible on the canvas to firePropertyChange() which is picked up by the Form with CUSTOM-EVENT trigger. This is fine, but if I now go to my code with a JPanel the firePropertyChange() method either doesn't get fired or the Form doesn't pick this up.
The code I am using is as follows:
public class EverySecondTimer extends JPanel implements Serializable {
String str = "DATA";
Timer timer;
public EverySecondTimer() {
setSize(60, 40);
timer = new Timer();
timer.schedule(new RemindTask(), 0, 1 * 1000);
class RemindTask extends TimerTask {
public void run() {
java.awt.Toolkit.getDefaultToolkit().beep();
firePropertyChange(str, "true", "false");
Like I said earlier this works if it extends Canvas, extending JPanel it doesn't.
Any ideas?
Is this the correct way to fire an event in a JavaBean for a Form to react to?
Any help would be most appreciated as I am struggling with this and finding any examples that don't use VBean is quite difficult.
Thanks in advance.

How to read the current value of hyperlink java bean in multiple record,

I have used a java bean for a multi-record block item. On When-new form-instance I m using fbean package as follows
FBean.Register_Bean(hHyperlink,1,'oracle.forms.demos.beans.Hyperlink');
FBean.Invoke(hHyperlink,1,'setURL','Abc_Entry');
FBean.Invoke(hHyperlink,1,'setLabel','Abc Document');
FBean.Enable_Event(hHyperlink,1,'actionListener',true);
You can see that I am using the number 1 which is hardcoded,for which I will replace with a incremental loop and remove it. Now when I m using the When-Custom-Item-Event, I want to read the URL for the current instance.
I m using
vcEventData := Fbean.Invoke_Char('CONTROL.HYPERLINK',2,'getURL');
to get the second record value , where in I want to avoid the hardcoded 2 or 1
Thank you

Using applets in forms 9i

i am trying to use an "normal" applet (myapplet) designed for use in a html-page
in forms9i.
properties in applet can be set as "<param name="image1" value="1.jpg">...
i used jdevloper to create a wrapper-bean:
new->beans->Oracle Forms Pluggable Java Component
extends: oracle.jdeveloper.pjc.BeanWrapper
optional attributes: bean: myapplet.
then i tried to define the property ids like:
private final static ID image1 = ID.registerProperty("image1");
what next? any howto's??? the pjc-demo from otn does not exactly describe, how to make a wrapper bean...
kind regards

Close - but you don't need the .class extension.
1) Copy the Clock.class into your forms90/java directory (or you can have it in a JAR and point to in the various Archive Tags - but let's just copy the class for the moment)
Then the code you need in your When-New-Form-Instance is something like:
FBEAN.REGISTER_BEAN ('BLOCK1.CLOCKAREA',1,'Clock');
That should create the clock in the bean area (I've just tried the Java 1.4 Clock and it works)
The calls to FBean.SET_PROPERTY() are not going to be the way to set applet properties on the Clock. FBean.set_property is for setting the values of public variables on the bean (if it has any and this one does not).
Setting the Applet properties is done like the forms applet properties themselves. So you need to update the template HTML file - in this case basejini.htm and add in the properties that this Applet uses to the ones the Forms Applet uses -
e.g. I added <PARAM NAME="bgcolor" value="FF0000"> to my basejini to set the background of the clock to Red.
The only thing you won't be able to change in this way is the Width and height. The size of the Bean Area effectively becomes the Applet Area in that case.

Webutil and Forms 10g

Hi,
I'm currently converting a forms 6.0 application to forms 10g. My application has the file upload and download functionality. I researched the webutil 9i beta version, but my infrastructure team would not allow this to be installed in the 10g app server production environment because it's not supported.
I looked into the OC4J fileupload and filedownload javabean that comes with the oracle 10g iDS installation. Is webutil built on these javabeans?
What are other alternatives I could use that I don't know about? Please help.
Last question, when will webutil released to production? I desparately need this utility since I don't know too much about JavaBean coding and tie to forms.
Thanks,
Jennifer

Hi,
the problem is that Forms Developer tries to acces steh bean, which requires ojsputil.jar to be set in the Forms90_Builder_Classpath. However, even then it wont work because the oracle.jsp.webutil.fileaccess class doesn't implement the IView interface or extends teh VBean class. You could use it with the FBean package which works with Beans that don't implement the Forms interfaces. However, the oracle.jsp.webutil.fileaccess class seems to be a JSP class which doesn't work at all in Forms.
The best way to approach bean development for Forms is to read this whitepaper
http://otn.oracle.com/products/forms/pdf/forms_in_java_world.pdf
and then install the Forms 10g demos and look at the source code. We do our best to comment the demo source so that you know what the code does.
