Importing java classes ?

I'm trying to use "Java Embedding" process activity to add a simple java snippet, this code needs a set of classes. I've copied the required jar files to \OraBPELPM_1\integration\jdev\jdev\lib\ext.
But I'm not able to figure out where to add the import statements for the classes that are needed in my java code.

you need to do that within the process tag ..
like
<bpelx:exec import="org.w3c.dom.Element"/>

Error while importing java class into oracle forms 10g

Hi
I have generated a web service client using jdeveloper 10g. It consists of complex type methods. I am trying to import the class files using java importer in oracle form 10g. I am able import all of them successfully except one. That one is the main method. Please see the error and suggest me how to overcome this error.
Exception occurred: java.lang.NoClassDefFoundError: oracle/jdeveloper/webservices/runtime/WrappedDocLiteralStub
Thanks in advance

Do you see oracle/jdeveloper listed in "Import Java Classes" when you try to import?
If not, make sure you add C:\DevSuiteHome_1\jdev\lib\jdev.jar to FORMS_BUILDER_CLASSPATH in registry
Also excetion indicates: oracle/jdeveloper/webservices/runtime/WrappedDocLiteralStub
If you typing it - type: oracle.jdeveloper.webservices.runtime.WrappedDocLiteralStub

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.

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.

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...

Import Java Classes impossible?!

Hello all!
I tried in Forms 6i to use the option "import Java Class". But i always get the error-message PDE-UJI001, which I didn't find in any documentation. This error occurred on two different systems, in Win2000 and Win98.
null

Hi Martin!
I had the same problem like you. What you have to do is the following.
One solution is to read the metalink, search for the exception and import java classes.
The second solution is:
setting the classpath to the importer.jar file and to your directory where the classes you want to import are.
And you have to set the path to jre\classic and jre\bin.
For more questions, feel free to ask

"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.

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;

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.

Forms6i - Import Java Classes

Hi,i need import java classes to Forms.When I choose in menu
Program/Import Java classes, program shows error: PDE-UJI001
Failed to create the JVM. I tried set classpath,paths but
nothing. Thank you for any tip:-)

Download and install the JDK 1.2.2.
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=%PATH%;c:\jdk1.2.2\bin;C:\PROGRA~1\JAVASOFT\JRE\1.2
\bin;C:\PROGRA~1\JAVASOFT\JRE\1.2\bin\classic
( 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\Apac
he\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
