How to import java Classes in report Builder

Hi, I want to import classes from a jar file into Report Builder (10 g). I'm not able to find my JAR in -- Program --> Import Java Classes option.
I have set the classpath pointing to my JAR.

Hello,
To import the Java classes:
Add your jar in the REPORTS_CLASSPATH
Launch Reports Builder.
Note:
You must launch Reports Builder now so that the new REPORTS_CLASSPATH is used.
Choose Program > Import Java Classes to display the Import Java Classes dialog box.

Implement Java Classes to Report Builder

Hi, I have problems implementing own java classes into the Report Builder. OK, let say I am running a simple report using STUDENT_ID and STUDENT_NAME. What I wanted to do is to concatenate a string "XXXX" to one of the records in STUDENT_NAME (e.g. STUDENT_NAME = 'Mary').
The Java class that I wrote has a static method:
public class MyAppend
public static String myMethod(String s)
     s = s +"XXXX";
     return s;
I also wrote a Formula Column in Report Builder called "TestFormula":
function TestFormula return varChar2 is
     StuName     varchar2(40);
     myStr     varchar2(40);
begin
select STUMST.STU_NAME
into StuName
from STUMST
where STUMST.STU_NAME= 'Mary';
->myStr := myappend.myMethod(myPackage.aobj, StuName);
return myStr;
end;
The error message I get when I compile this Formula Column PL/SQL is (with '->' pointing to the line):
Wrong number or types of arguments in call to 'MYMETHOD'
How do I correct this error?
Thank you.
Joey

Thanks Navneet. Actually I am new to PL/SQL programming. I have another problem here. I would like to list all the records of the STUDENT_NAME. How would I go about it using PL/SQL? This is the Formula Column I have written but it only shows me 1 record:
function TestFormula return varChar2 is
StuName     varchar2(40);
cursor c1 is
select all stumst.stu_name
from stumst;
begin
     LOOP
     open c1;
     fetch c1 into stuName;
     stuName := myappend.myMethod(stuname);
     return stuName;
     EXIT WHEN c1%NOTFOUND;
end loop;
end;
By the way, can you please give me any useful sites for reference to the PL/SQL?
Thank you.

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

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;

Import java class that uses DbConnection

How to import java class that uses DbConnection? I don't want to write my own PluginDataSource.
It is possible to get Connection in imported java classes?

This is not possible. Even connection used by individual PDS are only limited to those individaul PDS only and are not shared across them.

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

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

Forms 10.1.2 - Imported Java Classes are not running on JNI.NEW_OBJECT call

Hi All,
I've created a java class to call a webservice. This has been developed and tested in JDeveloper and works ok (using JDev Wizards - so it's generated code). I've created the JAR from it, imported the classes into Forms Builder and have my package and imported the java exception_ class too.
So, everything compiles and looks good. When I run the application I can see in the console that my JAR is included in the loaded list. When I call the class (basing my code on the Forms Webservice example here on OTN) it doesn't work. I get the error ORA-6503 - function returns no value.
I can step through the code in debug and it's in the generated constructor "new" function when the JNI.NEW_OBJECT is executed. I can't see into that so I'm a bit stuck ... I don't whether it's my java that is now failing or the system is failing to call it :
FUNCTION new(
    a0    VARCHAR2) RETURN ORA_JAVA.JOBJECT IS
BEGIN
    args := JNI.CREATE_ARG_LIST(1);
    JNI.ADD_STRING_ARG(args, a0);
    RETURN (JNI.NEW_OBJECT('oracle/forms/atrium/wsexport/proxy/AtriumExportWSSoapHttpPortClient', '(Ljava/lang/String;)V', args));
END;Has anyone any experience or pointers for me ?
Are there any extra JAR files I need to include in the CLASSPATH ?
Forms Builder is 10.1.2.0.2, the Application Server is 10.1.2.3 and it JDeveloper 10 compiling Java 1.4. All on a Windows platform.
TIA
Steve

Not sure if this is exact the document you are searching for, but this one works for me:
http://www.oracle.com/technetwork/developer-tools/forms/webservices-forms-11g-094111.html
It's for 11g, but I don't think there is much difference to 10g.
Did you add your Jar file also to the classpath in the environment file of your webconfig?
cheers
Edit: too slow somehow -.- heading for a cup of black coffee

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.

Import Java Classes

Hello,
Is anybody knows where i can find documentation about the Import Java Classes functions in Forms9i.
What they are, how to implement them, etc. ?

"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.
