If it is possible,can u send the sample code?Please help me to solve this problem

Rama,
Java Beans only work on the Web.
Btw.: There is a Forms discussion forum on OTN that is monitored by Product Management. Forms questions have a bettre chance for an answer if asked there

FRM-40735 with ORA-105100 when calling JavaBean in Forms6i deployed to Web

We are encountering an ORA_JAVA error during runtime in a new simple form when trying to call an imported JavaBean in Forms 6i.
It works when in the Forms6i Builder Run Form Client/Server mode on Linux/Motif.
The specific error is: FRM-40735:WHEN-BUTTON-PRESSED trigger raised unhandled exception ORA-105100
Our form incorporates the following simple example from Metalink Note:131964.1
How to Create a Simple Java program with the ORA_JAVA Package of Forms?
We have confirmed that we are downloading our custom JavaDev6i.jar file in the JInitiator console during runtime when deployed on the Forms Server using sockets.
We have turned on Forms Runtime Diagnostics (FRD), which showed the following
ORA_JAVA.LAST_ERROR: 121
when attempting to execute the call to the JavaBean.
I also ran strace on the forms processes:
strace -o/tmp/f60srvm_trc.txt -afeT -p 21192 &
strace -o/tmp/f60webmx_trc.txt -afeT -p 9172 &
I found libjvm.so could not be found in the LD_LIBRARY_PATH,
so I changed /d01/oracle/visappl/admin/adovars.env from:
LD_LIBRARY_PATH=$ORACLE_HOME/network/jre11/lib/i686/native_threads:$ORACLE_HOME/network/jre11/lib/linux/native_threads:${LD_LIBRARY_PATH:=}
to
JDK131_HOME=/usr/java/jdk1.3.1_20
export JDK131_HOME
LD_LIBRARY_PATH=$JDK131_HOME/lib/i386:$JDK131_HOME/jre/lib/i386:$JDK131_HOME/jre/lib/i386/classic:$JDK131_HOME/jre/lib/i386/native_threads:${LD_LIBRARY_PATH:=}
This solved that library problem, but it did not fix the original problem of not being able to run a JavaBean in a deployed Form.

Thanks for your help!

Looks like the CLASSPATH for the server is not set correctly. Does it include the directory where your JAR file resides?
You say that the JavaDev6i.jar is downloaded the the JInitiator, which surprises me. It looks like you are trying to import/call Java from the server side, which means it is not necessary to load the JAR client side. You only have to include it in the client side JARs if you are using Pluggable Java Components (PJC) which run client side. You are using the Java Importer which creates a PL/SQL wrapper around a server side Java class.
This might also explain why it does work in client/server mode. Then you might have a different CLASSPATH setup when starting Forms Runtime from within Forms Builder.

Now I want to know how to setup javabean on forms so that I can make my form work it way it should work. Please help.

you can get samples of using javabeans in forms in the form section of the otn.
but let me suggest something that might be simpler.
create the file on the server and then use:
web.show_document('url of file on server');
this will cause the file to download to the client.

Hi,
i Think you are using Oracle 8i.
Check if u have started the Listener. Go to Services and See if
the Listener Service for Oracle is running.
If Yes Then
Did u create the Service name in tnsnames.ora Using the net8
Configuration Utility.
If Yes Then
Did u Give that Service Name while connecting to the Database.
I think the first one is your problem. Check it out and revert
back if anything more is needed....

Forms6i and JavaBean

Hello!
Can i use Bean Area in forms 6i in client-server or this is possible only in web server?
Thanks!

This possible only in Web versions because the 6i C/S runtime process is not a Java applet.

How to attach a java bean in forms6i

Hi,
I am new to oracle forms6i. i just want to ask on how to attach a java bean to forms6i.i did putting the full directory path to the implementation class but it has an error, bean not found. what should i do?
Your help is highly appreciated.

The implementation class should contain the package and class name of the bean e.g. com.groundside.beans.DateFieldBean, not a directory location. The bean itself is loaded from the JAR files specified to be downloaded with the applet.
If you are running client server then you can't use JavaBeans this way - it's a web only feature.

Beans in Forms6I

I am trying to embed a bean in Forms6I on NT4 (the supplied BeanArea bean) but whenever I try to specify the Implementation Class, I get the error "FRM-13008 Cannot find Javabean with name 'oracle.demo.BeanArea'".
I have compiled the bean and placed it in the correct place in the directory structure...
Does anybody know what may cause this problem?

Have you read this collateral document ?

Java bean from oracle Forms6i

Hi Guys,
I am calling java bean from oracle Forms6i (implementation
class property set to bean class). This java bean in turn
calling some JNI methods written in C. The application server
(Forms6i) is hanging at the point of calling the JNI method.
Is oracle Forms6i supports all java functionality (JNI here)
and if so how to solve the problem ?
Any pointers or tips in this regard is highly appreciated ?
Thanks & Regards
Chandra Mohan

To call Java from forms:
look at the technical documents on Java integration at
http://otn.oracle.com/products/forms
and also look at the Javabeans and PJC samples in the sample
code section of Forms on OTN.
Creating a random number using a java class is an excelent
example of how to use Java with forms.

Using the GetClientInfo JavaBean

How can i get custom system property for example USER.DIR with GetClientInfo javabean, i m working with forms6i and try write this code,
declare
dirname varchar2(2000);
begin
dirname := get_custom_property('CLIENTINFOBEAN',1,'"USER.DIR"');
:ctrl.dirname := dirname;
end;
but this dont work

What do you see in the Java Console when you make the call?

Can not connect from Forms6i to PO8i.

Hi,
My PC is a NT named 'oracle'. I have first installed Forms6i in DEFAULT_HOME, c:/orant.
PO8i is installed as:
Oracle Home: ora8i
Full Path: c:\orant\ora8i
Choose Typical Install
Global Database Name: ora8i.oracle.master.com.au
SID: ora8i
Then I added an entry in c:\orant\net80\admin\tnsnames.ora as:
test.world
(DESCRIPTION
(ADDRESS_LIST
(ADDRESS
(PROTOCOL = TCP)
(Host = 127.0.0.1)
(Port = 1521)
(CONNECT_DATA = (SID = ora8i)
I can connect to PO8i from SQL*Plus using scott/tiger or scott/tiger@ora8i.
When I tried to connect to PO8i from Forms6i using scott/tiger@test or scott/tiger@ora8i. I got ORA-12154: TNS:could not resolve service name.
If I use scott/tiger@test from SQL*Plus, I got the same error.
If I use scott/tiger from Forms6i, I got ORA-12203: TNS:unable to connect to destination.
Help please.

What is the diffrence between a javabean and EJB

hi!
what is the diffrence between a javabean and entreprise jvaabeans! i mean which are the uitilization featires of eaxh one !

i am seeking for a solution for my problem , in fact i ma trying to implement and develop an application with java that allows a certain range of IP adresses to be connected to a database server in order to extract the suitable data from the server .
let me explain mor ethe suitation , in fact what i am loking for is to use javabeans to grant my application much more consistence and pertinence : si i am asking if it could be possible to use javabeans in my case especially if i am not trying to developp a web application but a cleint /server one allowing some services.
The application is in fact dealing with a stock exchange market and what i am trying to do is to grant particilar registrated customers to have the informations that they need ( portofolio, currency's status, market indicators, .) also drawing some charts decribing rates, variations, and others specefic financial caracterestics .So , if we consider that this application is not a web application ( no HTTP request and no servers like apache or others ) how it is possible to use javabeans and not EJB to build the application? i mean what could be suitable and preferable to rely on and dvelop to ensure a good java application !!
if you need more details to help you find the answer for me don't hesitate to answer me back !!
Someone here gave me that answer
use RMI to code the services and (Updateable) Value Objects to pass the information between tiers.
RMI is an all-java distributed component framework (ie. EJB, CORBA, DCE/RPC, DCOM, etc.), that is very suitable for developing non-containerized multi-tier applications. Refer to the RMI trail in the Java Tutorial as a starting point for coding RMI solutions (http://java.sun.com/docs/books/tutorial/index.html). Under this scenario you would code the database access service as an RMI service (server-side). Client/server communication should be facilitated through the use of JavaBeans/classes that wrap the information being passed (customer information, portfolio details, market information, etc.) - these are refered to as 'Updateable Value Objects' (a design pattern). Graphing and charting would be handled in your client from the information received from the (RMI) server. GUI JavaBeans can be used to provide this functionality as well as other client-side services. There are numerous "shrink-wrapped" components for GUIs available on the market just peruse any Java magazine to find them.
but how comes? how can i do it !! and where can i find more information please about 'Updateable Value Object "
thanks

Problem retrieving javabean instance from request in JSP

I am using WSAD and I created a javabean called confirmBean in default package which contains two private properties fname, lname and public setters and getters
In a servlet I placed values in the bean, then placed the bean in a request and then forwarded to confirm.jsp
confirmBean cb = new confirmBean();
cb.setFname("testing");
req.setAttribute("mybean", cb);
req.getRequestDispatcher("/confirm.jsp").forward(req,res);
Here is my JSP, I used java syntax for retrieving javabean:
<HTML>
<HEAD>
<TITLE>confirm.jsp</TITLE>
</HEAD>
<%@ page
language="java"
contentType="text/html; charset=ISO-8859-1"%>
<%@ page import="confirmBean"%>
<BODY>
<% confirmBean myBean = (confirmBean)request.getAttribute("MYBEAN"); %>
<%= myBean.getFname() %>
</BODY>
</HTML>
and here is the error i am getting when executing:
Error 500: Unable to compile class for JSP c:\testWorkspace\.metadata\.plugins\com.ibm.etools.server.core\tmp0\cache\localhost\server1\Test\TestWeb.war\_confirm.java:3: '.' expected import confirmBean; ^ An error occurred at line: 11 in the jsp file: /confirm.jsp Generated servlet error: c:\testWorkspace\.metadata\.plugins\com.ibm.etools.server.core\tmp0\cache\localhost\server1\Test\TestWeb.war\_confirm.java:78: cannot resolve symbol symbol : class confirmBean location: class org.apache.jsp._confirm confirmBean myBean = (confirmBean)request.getAttribute("MYBEAN"); ^ An error occurred at line: 11 in the jsp file: /confirm.jsp Generated servlet error: c:\testWorkspace\.metadata\.plugins\com.ibm.etools.server.core\tmp0\cache\localhost\server1\Test\TestWeb.war\_confirm.java:78: cannot resolve symbol symbol : class confirmBean location: class org.apache.jsp._confirm confirmBean myBean = (confirmBean)request.getAttribute("MYBEAN"); ^ 3 errors
Please help!!!!

1 - Put your bean in a proper package. As of Java1.4 classes in the default package are not visible :
http://bugs.sun.com/bugdatabase/view_bug.do;jsessionid=c85f07c1ce8f344d787b7a5146d68:WuuT?bug_id=43615752 - As a matter of style, class names should always start with a capital letter. ie ConfirmBean
3 - Rather than declaring the bean, and retrieving it, from the request manually, have a useBean tag:
<jsp:useBean id="MYBEAN" class="com.mypackage.ConfirmBean" scope="request"/>
of course the id has to be the same as the attribute in scope.
Hope this helps,
evnafets
