Java external procedure .....

Question

Hi, i am calling my java function from oracle but i am getting this error :
'ora-29541 : class Eadmin.com/XX/MyClass could not be resolver'
where com.XX is package name for MyClass.
My java class code:
package com.XX;
public class MyClass {
public MyClass(){}
public static String EString(String strText, String strKey) {
/**CODE**/
return **SOME STRING**;
I did following steps to load JAVA function:
1) create or replace directory bfile_dir as 'e:\oracle9i\bin\com\XX'; /*my class files are in folder 'com\XX' */
2)create or replace function plsEString(varchar2,varchar2)
return varchar2 as language JAVA NAME 'com.XX.MyClass.EString(java.lang.String,java.lang.String) return java.lang.String';
3) declare
str varchar2(200);
begin
str:=plsEString('maviner','hi');
dbms_output.put_line('str: ' || str);
end;

ORA-29541: class EADMIN.com/XX/MyClass could not be resolved

Where i am doing wrong?

Answer 1

I am using CREATE OR REPLACE JAVA CLASS,i missed that step in my first mail.
Is it possible that jdk version in oracle 9i is giving me poblem . Becoz for my java class i am using j2sdk1.4.2
I tried to deploy my class using Jdeveloper and i get this following error :
"ORA-29521: referenced name javax/crypto/NoSuchPaddingException could not be found"
I am importing javax.crypto in my class.
How i can update oracle java file to latest version?
