PJC and Bean Area
Is it possible to use a bean area or a pjc in forms client server mode, I mean not via a browser?
Kind regards

You can pull the 9i demos off OTN, this installs a whole bunch of PJCs for you.
Some advice:
Jar up your class - use the deployment options within JDev to do this. Then you can put the JAR file anywhere you want, but the location must be accessible as a virtual directory and you jhave to update the archive and archive_jini lines in your configs to point to the jar in the virtual directory where you've placed it.
I generally throw the jar into forms90/java directory along with the f90all.jar, although you'll see with the demos wwe put them into a forms90/demos/jars directory which has a virtual address pointing to it in the OC4J Config.

Developer 6i,Item type "User Area" and "Bean Area"
kindly I want to know how to use item type "user area" and "Bean Area",i never used them and i didnt find good help about them,and i appreciate any help with examples.
Hello,
I have forgotten what is the user area because it has disapear with the 9i version.
The bean area allows you to put some java bean component inside your Forms module.
Check out the demos available on the Forms OTN page

Hi
i have a bean area which display graph placed on a stacked canvas. i have set the stacked canvas to show the horizontal scrollbar. i want to allow user to scroll through the stacked canvas when the graph increase in width.
in my program, the bean area width would be dynamically change - increase the width depending on the number of data using
set_item_property('NAV.BA',WIDTH,690).
but the bean area does not seem to increase in width even when i set the property. why is it so?
appreciate any help. thx.
SitiHi,
did you try to change the size of the bean display that runs in the BeanArea. The bean area should adjust to the size of the bean displayed. I didn't find a bug filed on the issue of not being able to set the width and height of a JavaBean container. But I could find one for Forms 6.0.5 that was fixed in 6i about not resizing the bean container according to the resize of the embedded bean area.
If this doesn't solve the problem I recommend contacting customer support at metalink.oracle.com

ActiveX Control+OLE Container+ Bean Area. Help Required
I am a beginner and using forms 6i, where can i find detailed information about ActiveX Control,OLE Container and Bean Area.
Hello,
Forms 6i is a very old version and is unsupported for a long time. Are you forced to use this version ? If you are a beginner, why don't you start with the current version ?

How to disable and enable a java bean area's visability?
I have a large javabean area on my initial canvas when first dispalying my form.
When I use the SHOW_CANVAS('canvas name') to display another canvas, everything looks fine except that the javabean from my previous canvas is still visible and covering up portions of this new canvas.
So I tried using the set_property visible for the javabean area in the form and it only got rid of the surrounding edge of the javabean area.
Last I made some set_custom_property values to send to the bean that would then use java calls to enable and disable the beans visability.
But once the beans visibility was disabled in Java then it wouldn't come back after the calls to enable the visibility and refresh the bean were made through Java calls.
Is there any other ways of disabling and enabling a java bean area's visability?
Thanks,
MichelleHello,
Maybe the bean is always display because of its particular paint() method ?
Anyway, without any reflexion, I could suggest you to set the bean item width and height to 1 pixel when you don't want to display it. (Set_Item_Property)

A cmr-field and a cmp-field on the bean are using the same name. The names
Hi:
I am using weblogic 8.1 and MyEclipse 5.1.1. I am deploying my ear application through MyEclipse 5.1.1 as an ear file.
When I ran the following EJB QL:
SELECT OBJECT(p) FROM Product p.category = ?1
I get the following error:
n relation Category-Product, a cmr-field and a cmp-field on the bean are using the same name. The names of cmr and cmp fields must be unique.
It is basically complaining that I have a field
<cmr-field>
<cmr-field-name>category</cmr-field-name>
</cmr-field>
in my ejb-jar.xml and also the same category in the
<cmp-field><field-name>category</field-name></cmp-field>
field. The problem is that if I changed the value of the cmr-field, I have to add a get and set in my productLocal.java and when you do that you have to do the same in the ejb-jar.xml.
Here is my ejb-jar.xml:

Applet, images and the Bean Area
I've created a Java Swing Applet Bean that simply displays a GIF image that it receives via a URL. The Applet works well on its own, however, I have tried to register my Java Applet Bean with a Forms Bean Area and although I can see that something is happening (the bean area turns gray) I still cannot see the image etc.
What I've done is:
1)Created a Java Class that extends oracle.forms.ui.VBean and draws an image.
2)Next I JAR-ed the class and placed it, as well as dependent JARs in the IDS_HOME/forms90/java directory and added the JAR to the formsweb.cfg
3)Then I created a new form with a Bean Area.
4)Then I created a button with a trigger that when pressed calls fbean.register_bean('CUSTOMERS.FORMSMAPBEAN',1,'oracle.forms.fbean.FormsMapBean')
Does anyone have an idea what might be happening or how to make this work? Has anyone implemented an Applet within a Bean Area?
Thank You In Advance,
JustinMy pleasure. The procedure and code that I used to create a dynamic image Bean is the following. Please note however, that I am in no way a Forms developer and will probably not be able to answer Forms questions. Here it is:
1) I created a Java Class (Bean) called FormsImageBean using JDeveloper which extends oracle.forms.ui.VBean. The code looks like this:
*FormsImageBean is a simple bean that takes 1 argument via the method, getImageURL,
*which returns an ImageIcon from which to build a Swing Applet from. FormsImageBean
*extends Oracle Forms VBean such that the Swing applet can be used in a bean area.
*Because FormsImageBean does use sockets to reach outside of the applet (and Form) it
*must be signed or allowed via the java policy file in order to run in a public environment
* @author Justin Lokitz
* @version 1.0
package oracle.forms.fbean;
import java.net.URL;
import javax.swing.ImageIcon;
import oracle.forms.ui.VBean;
import javax.swing.JPanel;
import java.awt.BorderLayout;
import javax.swing.JLabel;
import java.awt.Image;
public class FormsImageBean extends VBean
private JPanel jPanel1 = new JPanel();
private JLabel jLabel1 = new JLabel();
public static ImageIcon img = null;
public static String UrlStr = null;
* default class constructor for FormsImageBean
public FormsImageBean()
try
jbInit();
catch(Exception e)
e.printStackTrace();
* Takes 1 argument and returns ImageIcon from URL.
* @param name ID
* @return Returns ImageIcon via URL parameters
public ImageIcon getImageUrl(String id){
try{
//create image
UrlStr = "http://www.foo.com?id=" + id;
URL url = new URL(UrlStr);
img = new ImageIcon(url);
catch (Exception e)
System.err.print("Something happened when trying to get get the image. Error: " + e);
return img;
* Initialization of the Swing applet
private void jbInit() throws Exception
jLabel1 = new JLabel(getImageUrl("135"));
jPanel1.add(jLabel1, null);
this.add(jPanel1, BorderLayout.CENTER);
2) I deployed this code as a JAR file, along with dependent JARs to the $DEVELOPER_HOME/forms90/java directory and signed the JAR using the java keytool.exe. I also updated the formsweb.cfg with the new JARs.
3) Next I created a form with a BeanArea called FormsBeanArea and referenced my full class, "oracle.forms.fbean.FormsImageBean", for the "Implementation class" property in the FormsBeanArea dialog.
4) After many tests, it worked.
Best Regards,

How to fetch data in a grid format in a bean area in forms 6i?
Hi,
I need help from all the gurus and experienced persons in forms 6i. I am trying to build form which will have some text fields and a bean area which will display the records that I had entered. Basically following is the basic form structure I am trying to develop
1. There will be a search form which will have two text fields 'Emp ID' and 'Emp Name' and two buttons 'New' and 'Find'.
2. Let there be another form which will have a bean area which will display the following columns in it in the form of a GRID
a. Emp ID
b. Emp Name
This form will also have two text fields 'Emp ID' and 'Emp Name'.
3. When I press 'New' in the search form then the second form should open and it will be blank. I can enter data in the text fields and save the form. The grid area (bean area) should be blank.
4. When I open the search form again and enter the 'Emp Id' I just created in the above step and click the 'Find' button then the next form should open and the 'Emp Id' and the 'Emp Name' text fields should be populated with the data I created in the step 3 and the bean area should also display the record in the form of a grid.
I am ok with all the parts except for the bean area part. Can you help me hpw to develop the form with the bean area and fetch data when searched for and display it in the form of grid?But still I would like to learn about the Bean being used in the Oracle Forms. I am not familiar with Java at all. So it would be very helpful from your side if you can give me some sample on how to use bean area in forms and fetch records in that in the form of a Grid.You don't need to know anything about Java in order to implement a Java Bean in your form. You simply need to know how Oracle Forms interacts with Java Beans and the When-Custom-Event trigger used to interact with Java Beans.
Francois Degrelle has a great web site (Oracle Forms PJCs/Java Beans) for learning how to use Java in Forms. I recommend you get started here. The biggest hurdle you will encounter is setting up your App Server or your local Forms Builder installation to use Java Beans. For some reason, Oracle has retired many of the documents on OTN that walked you through this setup. However, I can assume that you have access to My Oracle Support (MOS) since you are working with EBS 11.5.9. You should be able to find everything you need in MOS to help you set up your environment.

Add listener in HTMLPANE BEAN AREA
I have a Java class which interprets the HTML code (based on http://forms.pjc.bean.over-blog.com/article-1896785.html).
On the other hand I have another class that captures the key down (based on the exemple keypressed.zip in the same web page http://forms.pjc.bean.over-blog.com).
Both classes are in the same jar.
In my form I have a bean area that implements the HTML class, but if the focus is on this element ignores the key pressed.
The same thing happened with the buttons and adding the following code in the KEY class has been fixed.
protected void getTextItems(Component component, int iter)
if (component.getClass().getName().equals("oracle.forms.ui.VTextField"))
oracle.forms.ui.VTextField vt = (oracle.forms.ui.VTextField)component ;
vt.addKeyListener(kl);
else if (component.getClass().getName().equals("oracle.forms.ui.VTextArea"))
oracle.forms.ui.VTextArea ta = (oracle.forms.ui.VTextArea)component ;
ta.addKeyListener(kl);
else if (component.getClass().getName().equals("oracle.forms.ui.VBean"))
oracle.forms.ui.VBean abe = (oracle.forms.ui.VBean)component ;
abe.addKeyListener(kl);
else if (component.getClass().getName().equals("oracle.forms.ui.VButton"))
oracle.forms.ui.VButton btn = (oracle.forms.ui.VButton)component ;
btn.addKeyListener(kl);
if (component instanceof Container)
Component components[] = ((Container)component).getComponents();
iter++;
for (int i = 0; i < components.length; i++)
{ if (components[i] != null)
{ getTextItems(components[i],iter);}
The HTML class implements VBean, i don't understand why the next code hasn't effect
else if (component.getClass().getName().equals("oracle.forms.ui.VBean"))
oracle.forms.ui.VBean abe = (oracle.forms.ui.VBean)component ;
abe.addKeyListener(kl);
Some idea?
RegardsHi,
you will have to register this function as a custom ID and then handle the call in the set_property() method of the PJC.
If this method is supposed to only return a value, then use the get_property() method.
protected static final ID mTest = ID.registerProperty("MYTEST");
public Object getProperty(ID p0){
if (ID== mTest) then {
return "my string";
else
return super.getProperty(p0);
variable1 := get_custom_property('block.beanitem',1,'MYTEST');
Note that the code could contain typos as I was writing it from the top of my head.

How to save the bean area content to the database
DB version:10g
forms version:10g
Hi Guys,
I have used text editor PJC/java bean in my screen where i have attched it to "bean area" field.Iam able to do all the changes to the to the text entered in this "bean area" but when i save this in the database it says no changes to save.in my table the column type is Varchar2.
any ideas of how to save the changes of a bean area to the database???
regards@François Degrelle -Ya frank i have already checked Get_Custom_Property() but the problem is this is returning the HTML code like
html>
<head>
</head>
<body>
This is a <b>styled</b> (<i><u>HTML</u></i>) text<br><b><font color="#0066FF" face="Arial">
displayed</font></b> and <b><font color="#008000" face="Arial">edited</font></b><br>
in an <b><font color="#FF0000" face="Arial">Oracle Forms</font></b> application
</body>
</html>
but want the data to be in the formatted so that i can store the data in the column and retrieve formatted text into the text field so that user can see only the formatted text that is lets say
shdjshdsjdsdsdlas -original text
shdjshdsjdsdsdlas -formatted text
now i want to strore shdjshdsjdsdsdlas this text into teh database so that when i retrieve shdjshdsjdsdsdlas this data should be shown.
regards

"click" a bean area - programatically
After some searching, and finding unanswered questions from 2001... I post this question:
How can I programatically "click" a bean area from inside normal forms code? [forms 10G]It all depends if your bean contains a clickable element.
check out the PJC samples on OBE (oracle by example)
eg the calendar bean is a java button displaying a calendar . -
Two phase commit and bean managed transactions
To all the Transaction GURUS!
Hi guys (-and gals).
I've been doing J2EE for quite a while, but today was my first at
XA-Transactions and Bean Managed Transactions.
Why am I doing this?
====================
Well I have to be able to controll the transactionalbehaviour of my
bean
during runtime, since some bean calls would cause a transactional
overflow due to the stress they would cause to the system, whereas
smaller bean calls need to run in one transaction.
-> Therefore I need Bean Managed Transactions
Since the bean does a call on two Database Connections it has to use a
XA-Transaction.
-> Therefore I need XA-Transactions.
Abstract
========
- I just can't get a User TransAction into the right Status it stays
in 'STATUS_NO_TRANSACTION' all the time
- Therefore the SQL Commands can be comitted 'java.sql.SQLException:
Does not support SQL execution with no global transaction'
- Therefore I can't do a rollback 'java.lang.IllegalStateException:
Transaction does not exist'
- Therefore I wrote this mail.
I don't want to be a smart-"ass" writing such a detailed and indepth
mail. I just would like to show that I tried, and would like to have
some replies from you guys.
Below are my configurations, code and logfiles.
Thanx for taking your time and hope that the other people may learn
something as well.

CONCLUSION
==========
I'm going nuts.
I just don't get it.
The transaction is the same. I don't change the Connection. I start
the Transaction at the beginning before I do anything!
Please guys help me out.
Thx alot.

Hi Priscilla
(did you ever see the movie ? :-))
Well I moved away from the idea of using bean managed transaction. I'll
be using Container Managed Transactions. To modify the
transactionalbehaviour I'll write proxymethods which have certain
different containermanaged transaction properties, but which all call
the same private methods.
But it works! Here is my experience:
- I was doing a DDL statement: I was trying to create new Tables, which
is a definite "no-go"
- pay careful attention to:
http://edocs.bea.com/wls/docs60/jta/trxejb.html#1051405
and
http://edocs.bea.com/wls/docs60/jta/trxejb.html#1051741
and use these Settings for the Pool, don't ask me why, but it took me
hours to find it out by myself:
<JDBCConnectionPool CapacityIncrement="5"
DriverName="weblogic.jdbc.oci.xa.XADataSource" InitialCapacity="1"
LoginDelaySeconds="1" MaxCapacity="2" Name="oracleSecurityPool"
Properties="user=xxx; password=xxx; server=xxx.xxx.xxx"
RefreshMinutes="5" Targets="fbsserver" TestConnectionsOnRelease="true"
TestTableName="Users" SupportsLocalTransaction="true"/>
where as the server (shown as: xxx.xxx.xxx) is the TNS Name of the
Oracle Driver.
It works great.
Another thing you guys might want to do is write a simple StatelessSB
which does JDBC calls and two different database Connections.
Then write a UnitTest which calls this bean a couple hundred times (with
the same transaction). Have one test do clean writes, and another which
causes some SQL-Exception (too long Data Columns, or likewise).
Always count the entries and see if everything worked out. We're using
this SetupConstruction to test new combinations of AS(sorry Priscilla) /
Database / Db-Drivers to have a "standard test".
I know my two cents were uncalled for, but it might save you some
time.....
thanx for your help
Stefan

Hi Stefan,
Looks like you have not actually begun a transaction by calling
UserTransaction.begin(),
so your setupTables method is really executing with no transaction
context.

The above error caused the server to use all available memory and required a reboot to proceed.
Subsequent testing against the Sun Appliucation Server 7 on Windows 2000 dev environment using the Sun Studio IDE for debugging and trace statements inserted in the code indicate that the Application Server is removing the Stateful Session Beans when they time out without an ejbPassivate event and without serializing the beans to the data-store. cache-idle-timeout-in-seconds set to 180 and removal-timeout-in-seconds set to 1800.
The server.log indicates that the beans are timing out:
[19/Aug/2004:18:15:10] WARNING ( 1664): [NRU-com.telstra.nodeman.ejb.AddressMaintBean]: IdleBeanCleanerTask finished after removing 2 idle beans
Trace statements inserted in ejbPassivate do not appear in the log.
It is my understanding that the above timeout should have caused an ejbPasssivate and serialization of the beans.
The beans have been validated using Sun Java Studio Enterprise 6 with 'EJB validate'.
My reading of the problem is that the beans are not being serialized and the error occurs when the application attempts to reference (getHandle) the bean after timeout.
Any suggestions would be appreciated.Thanks Thorick.
I am using NRU caching. WL 7.0 SP2.
I have not defined idle-timeout-seconds in my weblogic-ejb-jar.xml. As I understand
the default value for this is 600secs. So the ejbs should be removed after this
time. Below is the
weblogic-ejb-jar.xml that I am using.

The idle-timeout-seconds property controls the timeout/removal behavior.
which stateful session cache type are you using ? LRUCache or NRUCache -
How to embed excel in java bean area on oracle forms 9i?
Hi,
I am trying to embed excel in oracle forms 9i using java bean. I want to open excel sheet in the bean area not as seprate application. Means i donot want to excel running separately from forms on the machine.
If any body knows the solution please reply.
Best regrads,
ShirazHi
Is it possible to create a java bean, with a click event which populates data from database table to an excel sheet.
The data(can be obtained in a string format with delimiters, but can anyone help me in exporting this into an excel sheet). and also to provide user to take prints of the data in the excel sheet.
If Print of the JTable could be done(by settin printable as this), but this involves unwanted buttons to be printed, and entire table is not available in the spread sheet format.
Thanks in Advance

Problem importing classes and beans
Hey there. Im having one major fustrating problem! When I code supporting classes and beans for my JSPs I get a code 500 internal server error when trying to import (via <%@ page import="class" %> and <jsp:useBean/>) Im storing my classes and beans in the WEB-INF folder and the calling JSPs are located in /ROOT/tests/8/jsp.jsp. Im using the following to import a class or bean:
<%@ import="aClass" %>
Seen as tho its in the WEB-INF folder I won't have to explicitly refer to where the class is located, just the class name.
I never had this problem when I was using my hosting service. Its only on my localhost server in which I get the Internal Server error.
Help appreciated, thx.
PS: Im quite new to JSP/Java Servlet.import (via <%@ page import="class" %> and
<jsp:useBean/>) Im storing my classes and beans in the
WEB-INF folder try put your class file in WEB-INF/classes.
or first put bean in the package, like WEB-INF/classes/packagename/beanclass
in jsp page:
<jsp:useBean id="Mybean" class="packagename.beanclass" scope="request" />
Question: is /ROOT a context entry in your server.xml?
Which JSP Container (version) you use? Maybe your localhost server's set up is different with your hosting.
Maybe you are looking for
