Exception : importing java classes
Hi all,
I'm trying to import java classes in forms 9i, but it generates me this error :
Import de la classe prj.proxy.MyWebService1SoapHttpPortClient...
Exception : java.lang.NoClassDefFoundError: oracle/webservices/transport/ClientTransport
Please give me some help with this issue.
For the importer to work, your jar-file must be part of the CLASSPATH-environment-variable-setting. If you're classes to be imported contain references to external classes (as you to with your webservices), that jar-file must also be part of the CLASSPATH.

Error while importing java class into oracle forms 10g
Hi

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 advanceDo 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 -
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.
nullHi 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.

Importing Java Classes for Bussiness Logic in Forms6i
I have created a Java Class with some bussiness logic in it and i m able to impotr it in Forms 6i BUT when it converts my java method into program unit it automatically changes the name of the method with some code ..like method name is "increment" it will make it as "increment_3137" and also one parameter of Ora_java.object type will be added ....WHY is THAT ???and how to work for hat ...even when i m executing the method with the parameter it gives some Exception that Non-Oracle Exception ...and my class individually runs perfectly fine ...CAN U HELP ME ASAP ...Please as its urgent
Thanx..Once you have imported java class files on forms throgh java import class option..
it creates a pl/sql for the java class that you have imported.
names for the procedures are assigned by machine code, so dont worry about it..
for eg. if the name of a method in java class is Increment and after loading java class file the name of ur pl/sql is increment_1254.
when u call increment_1254 and pass parameter to the procedure ur class incerement will be called and desired operation will be performed.
ora_java.object is the objec that will be used to access the the class file.
as java is object oriented it requires a object to execute method of class.
so u have to initialize the object..
e.g. increment_1234 (ora_java.object,a,b) is ur procedure
to call this procedure do the following
declare
PASS ORA_JAVA.JOBJECT;
a,b integer;
begin
pass := <classname>.new; --new will be created if ur class is public or u got public constructor in ur class.
increment_1234 (pass,a,b) ; -- increment_1234 (ora_java.object,a,b) ;

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
AnilHi,
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, ChrityIt 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"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
AsifOK 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 AMSarah, 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;
