Calling java beans from forms 6

Could anyone please tell me if it is possible to call an EJB component from within forms 6.
And if so how.
Thanks

If your EJB is for doing some server side processing, etc. you can consider exposing it via a servlet deployed on the Forms 6i server that accepts GET requests. You can then call to the servlet using utl_http.request.

Calling Java Bean from Form 9i

Dear all,
I have developed a Java Bean and I want to use it in FOrm 9i. I have imported that Bean (.jar file) sucessfully to my form. I use following code to call the Bean:
declare
WordDoc ora_java.jobject;
javaException ORA_JAVA.JOBJECT;
Begin
WordDoc := WordBean.new;
WordBean.OpenWord(WordDoc, true);
EXCEPTION
WHEN ORA_JAVA.EXCEPTION_THROWN THEN
javaException := ORA_JAVA.LAST_EXCEPTION;
message(Exception_.getMessage(javaException));
ORA_JAVA.CLEAR_EXCEPTION;
WHEN ORA_JAVA.JAVA_ERROR THEN
message(ORA_JAVA.LAST_ERROR);
ORA_JAVA.CLEAR_ERROR;
end;
But I receive the "raise unhandled Exception Ora-105100" and my form doesn't handle the errors. What am I missing in the code?
Thanks in advance,
Hamid Motahar

Hi,
You receive this error because at runtime the form can't find the jar. See note : http://metalink.oracle.com/metalink/plsql/showdoc?db=NOT&id=169529.1

the web-inf/classes/your_bean.class directory of corresponding web application

How to call java bean from jsp

hi
How to call a java bean from jsp page..
Is any other way to call javabean from jsp page apart from this sample code...
<jsp:useBean id="obj" class="com.devsphere.articles.calltag.TestBean"/>
thnx in advance

If you also use servlets, you can attach beans to the request or session and use them directly in your JSP's. So if you do:
request.setAttribute("name", yourBean);and then forward to a JSP, you can reference the bean like:
${requestScope.name}

First reaction: yuck.
This is not something you should be using a bean for.
Beans are meant for storing data, not for generating HTML from.
I don't really like queries on a JSP page either, but thats a different story again.
I would recommend you use JSTL for this.
1 - it provides a c:forEach tag for looping
2 - it provides sql tags for doing queries in a database
IF you are going to do database queries from a JSP page, I absolutely recommend you use the JSTL tags.
(end rant)
Your problem is probably caused by the fact that in your bean you have the following
try{
// code here
catch (Exception e){
// completely ignore exception and carry on as if nothing bad happened.
// what you should be doing is something like:
System.out.println("Error occurred " + e.getMessage());
e.printStackTrace();
return e.getMessage();

How to call Java class from Forms 6i?

Hi friends,
I need to call a Java class from my Forms 6i application.
(It runs under WIndows XP. It's a client/server application and I have only the client and the Form builder installed on my PC)
I don't know almost anything about Java's world so your help would be very useful for me.
Could you tell me exactly what i have to do?
I've read in metalink several Notes, but they supposed that the Java architecture is already installed in the computer.... I only have the default installation of Developer 6i... so I would need to know:
- How to install/configure the neccesary to execute Java classes without problem
- How to invoke the .class from Forms 6i.
Thanks a lot
Jose.

And also this one:
Problem Description
Installed Forms 6i Rel 2 on a MS Windows machine. When trying to Import the Java
Classes getting the errors
PDE-UJI0001 Failed to create the JVM
Solution Description
You need to to install JDK 1.2.2 to run the Java Importer. And set the PATH's
and classpath's correctly.
Explanation
1. Download and install the JDK 1.2.2.
Possibly available at: http://java.sun.com/products/archive/
2. Assuming the JDK 1.2.2 is installed in c:\jdk1.2.2 directory and the JRE in
C:\PROGRA~1\JAVASOFT\JRE\1.2 directory; ORACLE_HOME=C:\Dev6iR2.
Set the PATH to
set PATH=c:\jdk1.2.2\bin;C:\PROGRA~1\JAVASOFT\JRE\1.2\bin;C:\PROGRA~1\JAVASOFT\JRE\1.2\bin\classic;%PATH%
( If you are using ias9i then the JDK 1.2.2 comes with the ias installtion ,
in this case please set the PATH to
D:\ias9i\Apache\jdk\bin;D:\ias9i\Apache\jdk\jre\bin;D:\ias9i\Apache\jdk\jre\bin\classic;%PATH% )
3. Set the CLASSPATH to set CLASSPATH=%CLASSPATH%;C:\Dev6iR2\TOOLS\COMMON60\JAVA\IMPORTER.JAR;.
(If you do not set the CLASSPATH correctly you will get the error
PDE-UJI002 Unable to find the required java importer classes)
4. Now run the Forms Builder by using the command.
C:\Dev6iR2\bin\ifbld60.exe
Now the Java Importer Should Run fine.

Can we run java bean from forms client server??

Hi,
The OLTP application we are planning to build has lot of gui e.g
tabs, drag and drop etc. Our aim is to make it web enabled but
the network bandwidth available is small 16 - 64K . So even
thoughwe plan toi use applet , we seriuosly doubt how good it
will perform on such low network bandwidth. [The system will
have 100 users]
Q1. What will be a reasonable bandwidth to run an oltp
application (say maintenance )
Hence we are thinking of developing with developer 6i and
deploying our application in client server mode, which can
easily be web enabled in future. But we also have to integrate
visual interfaces like gantt chart, which are not available with
forms. We plan to use third party java component (e.g ILOG
jviews), so that in future we can easily web enable the entire
application.
Q2. Can we run forms with java bean in client server mode? If
not, what are the products to be installed on each machine to
run it without using 9ias?
best regards

Yes. We can run sql loader from client machine.
C:\Karthik>sqlldr user/pass@database data='test.csv' control='test.ctl' log='test.log' bad='test.bad'
You can go through the following link for better understanding.

Call Java (Beans) from VisualBasic/COM?

Is this ActiveX Bridge (that come with the Java Plugin) suitable for Visual Basic programmers to call Java classes/beans/applications?

yes.
i have developed some tutorials etc. that use VBA that you can see here

i am also using the Bridge for a client server app with RMI where the
client is VB and the server is Java.

Calling Java Classes from Forms 6.0

Can this be done?
How can it be done?
And, I don't mean JavaBeans... I don't want to embed a control
on my form... I want to call a standard java class routine.
Any help or laughter would be appreciated...
Thanks,

You have to write a wrapper classes so forms can call your java,
if you've got any yet.
Then use the Bean Area tool to draw the area your applet will
display in (if you don't want to display anything then don't
display anything in you java).
Its not really JavaBeans more like oracleBeans.
I've had to re-write functionality for the web such as
displaying open/save file dialogs.
If your interested and you've installed dev60, the example:
C:\orant\FORMS60
\java\oracle\forms\DEMOS\SOURCE\ProgressBarPJC.java and
ProgressBar.java got me started with alot of reading from
http://java.sun.com/products/jdk/1.1/docs.html

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

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.

Accessing Java Classes from Forms

Calling SQL*Loader from Forms

Hi,
I was wondering if anyone has called SQL*Loader from Forms?
What I am wanting to do is use Oracle Forms as the interface where you can specify a file that you can import into the database and it will use a set control file. Push the import button and SQL*Loader does the rest.
Is using Java code to call SQL*Loader from Forms a viable option, or is there an easier way to achieve the desired outcome.
Any ideas or guidance will be much appreciated.
Thanks,
Scott.

Scott,
In forms, there's a HOST built-in command which is supposed to execute any o/s commands.
What you have to do is :
1. Bult up the string exacltly in the fashion which you will run in o/s
2. Call the HOST Built-in and pass in the string
Here's a example :
Declare
lOsCmd Varchar2(1000) := Null;
Begin
lOsCmd := 'sqlldr user-id=userid/passwd@connectStr '
|| ' control=c:\temp\abc.ctl log=c:\temp\abc.log '
|| ' bad = c:\temp\abc.log';
Host (lOsCmd, No_Screen);
End;

Canot call Weblogic Bean from Delphi via JNI

I tried to call a bean within the weblogiv server 7 from Delphi.

It seems that i canno create a context object, but i do not know why ...
So i would be glad if anyone could help me here ...

I would try this with the newest service pack since it seems this assertion does
not exist in later code lines. It appears to be related to a class loader
issue. Do you know what version of the Java VM Delphi uses?
