How to run the imported java class in form

Help!!!!!
Pls help me to run the imported java class in forms.
Package is created in forms while imported one class called
singlexml.class and that package has one procedure and one
function.
I just wanted to run that class.I mean the new package.
Thanks
Anil

Hi,
It is because the converter works on byte code and it only supports a subset of the Java language (see the JC specifications). It is kind of like compiling you code on Java 6 and trying to run it on Java 5. The JCDK outlines the required compiler version.
Cheers,
Shane

Accessing Java Classes from Forms

Is is possible to access a Java class from Forms? I have been
creating an Active X control that returns a Java object, and from
that I can call methods on that object, but I would really like
to do that without having and Active X control in the mix. Any
suggestions?

Cannot import Java classes to form

I am using Forms Forms [32 Bit] Version 10.1.2.0.2 (Production).
I want to use the Persian Calendar from this web-site http://persiancalendar.sourceforge.net/.
I download the stuff and there are 2 JAR files.
I did this:
-- Put the JAR files in my E:\Ora_Dev_10g_R2\forms\java directory
-- Made an entry of these 2 in the E:\Ora_Dev_10g_R2\forms\server\formsweb.cfg file
Now, when I open a form and got IMPORT JAVA CLASSES, I Can't see the classes.
The directory structure of the 2 JAR files (after expanding is like this):
persiancalendar.jar
-> E:\Ora_Dev_10g_R2\forms\java\persiancalendar\com\ghasemkiani\util
-> under util there is the sub-dir icu
icu4j_3_2_calendar.jar
-> E:\Ora_Dev_10g_R2\forms\java\icu4j_3_2_calendar\com\ibm\icu
-> under icu there are these sub-directories impl, lang, math, text, util
The E:\Ora_Dev_10g_R2\forms\java is in my CLASSPATH:
C:\>echo %CLASSPATH%
.;e:\Ora_Dev_10g_R2;*e:\Ora_Dev_10g_R2\forms\java*;D:\Program Files\QuickTime\QTSy
stem\QTJava.zip;

Scott,
I agree with Abdetu, you should create your own thread for your question. However, to set an environment variable in UNIX you declare the variable and then export it. For example, in your default profile you could add the following:
FORMS_BUILDER_CLASSPATH='Your Path Here'
export FORMS_BUILDER_CLASSPATHCraig...

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.

Importing Java classes in Forms 6i

Hi
When I try to import java classes using the option available in forms 6i,I get the following error
PDE-UJI001 Failed to create the JVM.
ne clue?
Thanks
Gangs

You have installer the JDK 1.2 (This software located in a Sun Microsystems Web Site), and you have a configure the your PATH:
PATH=%PATH%;< path your JDK installed >;
If you have Designer 6i installed in your machine, then your Enviromento Variable PATH = PATH=< path your JDK installed >;%PATH%;
After configure the PATH, you have a create another Enviroment Variable CLASSPATH with:
Example:
CLASSPATH=C:\oracle\designer\TOOLS\COMMON60\JAVA\IMPORTER.JAR;c:\jdk1.2.2;
Test your Forms 6i.

Can't Import java class in form 10g

Hi All,
I have tried to call a web service from oracle form 10g
so, I read your available document (How to call Web service from Form 10g)
http://www.oracle.com/technology/obe/obe_as_10g/deploy/callws_fromforms/forms_webservice.htm#r1
but when I've created a web service from WSDL file and I've deployed it to JAR file using Jdeveloper 10g (10.1.2.1.0).
I tried to import it into form builder 10g but i have the error :
java.lang.NoClassDefFoundError: oracle/jdeveloper/webservices/runtime/WrappedDocLiteralStub
Please, can any body help me to solve this problem?

Have you put the jar file in the classpaths??

Invoking Java classes from Forms

We are running an AIX Forms server, and we would like to be able to execute a java class with two command-line parameters (ex. "java myClass.class param1 param2"). Is the "java" run-time executable available on AIX? I'm assuming it would be part of the JRE installed with Oracle 8.1.6, but where might I find it, and can it be called with the HOST() command?
Thanks,
Jonathan

I think if you have forms server installed you will have a java runtime there on the disk somewhere.
Regarding activating the java check out the "java importer" tool that comes with patch 4 of developer 6i.

Import java class from model package

I have a java class in model package.I create a managed bean in the view package and I want to import the first java class with "import model.class1" but this error "import model.class1 not found" is shown.What should I do?

Hi,
Why are you importing the Model classes to your backing bean? You should not be doing that. Instead, expose the method in model as client interface (whichever you want to call in the backing bean), create the method binding in your pagedef. Then, from the backing bean, you can execute the method programatically.

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

"Import Java Classes"in Oracle6i Forms

Hello
I have two questions regarding importing java classes in Forms 6i
1- How we can add my own class to this list, so that I can import it directly in form 6i and use it?
2- When these classes are used in form development, are they fully imported to client side or only class wrapper is ported to forms. I m asking this question, cuz I want to develop my application with all bussiness logic(Java classes) in middle tier ie Form Server.
Can anyone guide me in this regard
Thanks in advance
Asif

OK answers to the questions are:
1) If your class is on the classpath it will be picked up by the Java importer but you have to restart Forms if you add the class to the path
2) THe java importer is for middle tier. In Forms, all ofthe application logic is on the middle tier and if you want it integrate this with Java the importer will create a PLSQL wrapper to call the Java - in pretty much the same way as ORA_FFI. (So NOT imported into the client)
There are some white papers on OTN.

Importing Java class problem!

Hello
I have problem by Importing java class into form. When I select in Forms Builder from menu: Programs/Import Java Classes it returns error: PDE-UJI001 JVM not able to create!
Can someone know what I must do to fix that problem?
Thanks, Chrity

It is a shame because it, probably, contains no special 1.5 new instruction at all.
Maybe it would be possible to try replacing the current JDK/JRE of your <ORACLE_HOME>/jdk installation after a safe backup of course.
You probably have a very little chance that it works, and it also won't be supported.

PDE-UJ1001, while trying to import java classes.

Hi,
When I try to import java classes into forms using the java
importer, I get an error stating PDE-UJ1001-Failed to create
JVM. I tried installing a patch in Developer 2000(Path 4a). But
still it doesnt work. Could anybody guide me in this?
Thanks,
Karthick.

am getting similar error - my dba has suggested that oracle developer uses the jvm from ie4 but i'm sure that cant be true as i thought the jvm was built in.
could somebody out there clarify this or inform me whats missing..
error
from dev 6i forms builder (6.0.8.11.3) on 8i (8.1.7.2.0) when trying to select option 'import java classes' from program menu returns error 'PDE-UJ1001 Failed to create the JVM.'

Problem When Import Java Class -compilation error

Hi all
I made a java class that has methods to return Screen width and Height .
package tarek;
import java.awt.Dimension;
import java.awt.Toolkit;
public class Screen
Dimension dim ;
public Screen()
dim = Toolkit.getDefaultToolkit().getScreenSize();
public double getWidth()
double w = dim.getWidth();
return w;
public double getHeight()
double h=dim.getHeight();
return h;
I made the jar file " screen.jar" and make it ready to use in form builder
I opened form builder and make import java class (From program>import java class>choose the class anc click import)
The class now imported successfully and the PL/SQL package body is:
PACKAGE Screen /* tarek.Screen */ IS
-- DO NOT EDIT THIS FILE - it is machine generated!
-- Constructor for signature ()V
FUNCTION new RETURN ORA_JAVA.JOBJECT;
-- Method: getHeight ()D
FUNCTION getHeight(
obj ORA_JAVA.JOBJECT) RETURN NUMBER;
-- Method: getWidth ()D
FUNCTION getWidth(
obj ORA_JAVA.JOBJECT) RETURN NUMBER;
END;
Now I made a button on the form and i WRITE THIS CODE TO INVOKE THE CLASS on when_button_pressed
DECLARE
vScreen_Class ORA_JAVA.JOBJECT;
BEGIN
vScreen_Class := SCREEN.NEW;
END;
My problem is I have compilation error
error 306 AT LINE 5 , COLUMN 25
wrong number or types of argument in call to "NEW"
I do not know what is the reason of this compilation error?
Is it because the method in java return "double datatype" while in oracle return "number datatype"
Please help
Edited by: [email protected] on Dec 28, 2009 10:24 AM

Sarah, I ca not move my thread to JDeveloper because it is not java issue. The problem is with my PL/SQL code and the way I make Import Java class to forms Builder. The Java code is OK.
Andreas Thank you so much for replying. In fact I made a full compile "Ctrl+Alt+K". but still error
The following is the package Body
PACKAGE BODY Screen IS
-- DO NOT EDIT THIS FILE - it is machine generated!
args JNI.ARGLIST;
-- Constructor for signature ()V
FUNCTION new RETURN ORA_JAVA.JOBJECT IS
BEGIN
args := NULL;
RETURN (JNI.NEW_OBJECT('tarek/Screen', '()V', args));
END;
-- Method: getHeight ()D
FUNCTION getHeight(
obj ORA_JAVA.JOBJECT) RETURN NUMBER IS
BEGIN
args := NULL;
RETURN JNI.CALL_DOUBLE_METHOD(FALSE, obj, 'tarek/Screen', 'getHeight', '()D', args);
END;
-- Method: getWidth ()D
FUNCTION getWidth(
obj ORA_JAVA.JOBJECT) RETURN NUMBER IS
BEGIN
args := NULL;
RETURN JNI.CALL_DOUBLE_METHOD(FALSE, obj, 'tarek/Screen', 'getWidth', '()D', args);
END;
BEGIN
NULL;
END;
