Java Equivalent Function to Obfuscation DES3 Procedures
I've read all of the notes and reports that I could find on both OTN and MetaLink, but I can't find a solution anywhere. Just hints, particularly in Note 232000.1 and Note 225214.1. I've been trying all of the variations that I can think of in test code with no success. I've also searched the net extensively.
What I need is a code sample IN JAVA that provides equivalent functionality to the des3encrypt and des3decrypt procedures using raw values in the obfuscation toolkit.
We have a number of huge databases in which we would like to use the obfuscation toolkit with DES3 3-key (192-bit) keys to manage encrypting
confidential data. We need to be able to read this data from Java applications. Those applications must be able to decrypt the values encrypted using the toolkit. We must also be able to do the reverse, encrypt data in Java, store the encrypted values, the decrypt and access the data in PL/SQL using the toolkit.
I've searched high and low, but I cannot find sample code anywhere for performing this functionality in an equivalent fashion.
Thanks!

Hi Mark,
I encountered a similar challenge, were you able to figure out the solution for this problem?
Thanks,

How to return custJava Object from Java Stored Function/Procedure to Java Application
I WILL PAY $100 FOR SOLUTION.
Oracle JDBC documentation gives step by step on how to return Oracle Type Object to Java Application. No question here.
But is it possible to create Java Stored Function [getMyClass() ] which returns CUSTOM Java based object [MyClass] to Java application like:
//java stored function
class Foo
public static MyClass getMyClass()
return new MyClass();
//java class I want to return to Java
class MyClass
public String getGreetings(String name)
return "Hello " + name;
I tried to do it using intermittent Oracle
Type Object and OracleConnection map to make binding between Java->Oracle->Java. I could
not get throgh meaningless run time ORA Errors. Any kind of help would be greatly
appreciated. If you know the answer please
post it or e-mail [email protected]
nullYou don't say which version of the database you are on. There's an interesting looking article on OTN on handling CLOBs in JDBC in 10g. It may well be useful for earlier versions too (but no guarantees).

Function and triggers and procedures
sorry to asking this question,
In oracle. we use the function and triggers and procedure.
for eg:
if we wrote an trigger for a table. it fires at a time manipulating table. (database contains table contains datas and database also contains triggers likewise function,procedure).
but my questions?: is
In my database I kept only tables. no triggers,no function,no procedures. and
i dont want to kept this triggers, function, procedures in database Instead of i want to kept this triggers, function, procedures in business logic layers(middle tier)
is it possible? .
if yes means, how to write or where to write? please help me, or else send the guidance documents or blog releated to it.Subu123,
the +1 related to Would be great if you can take step back and see the implementation from another angle. First see why do you need DB trigger/function etc.Then check whether it is possible to implement the functionality using ADF BC + feasibility study between 2 approaches(I didn't mean to invoke DB objects from business components, instead checking the feasibility of implement the same functionality in your EntityObj/ViewObj/Service calls )Before making a decision for or against holding fuctions, triggers and procedures in the DB, you have to get the whole picture.
Think about a trigger outside the DB. What could this be and why or for what is it used?
All the answers are pointing to 'lets keep them in the DB'. Now there are situation where you don't have a DB or are not allows to use it. Still there can be triggers, only they are implemented in a different way.
The same can be said for procedures and functions.
So you have to think about the whole problem and how each sub problem you have to solve work together to resolve the whole problem.
I'm personally tend to keep the business logic the the DB if the business logic is already there (e.g. I have to migrate an old forms app).
If I design a new app I tend to keep the logic in java. Only sequences (for generating ids) and some other stuff which is purely db related like cleaning up tables I keep in the DB.

Why returning string from java stored function failed ? HELP ME, PLEASE
Hi everybody,
I created java stored function: it's doing http post, parsing xml from http reply, and returning string result.
Sometimes, it doesn't return any value. What can be a reason ?
The high level procedure, has following form:
class SBE {
public static String call(String arg0) {
SBE sbe=new SBE("d:\\oracle\\ora81\\network\\log\\SBE.log");
String result=SBEParser.go(sbe.sendRequest(arg0, ""), sbe.logger);
sbe.logger.log(result);
sbe.logger.log("Finish SBE intetraction");
return result;
PLSQL wrapper has a simple form:
create or replace package PG_SBE as
function CALL(arg0 in varchar2) return varchar2;
end;
create or replace package body PG_SBE as
function CALL(arg0 varchar2) return varchar2 as language java name 'SBE.call(java.lang.String) return java.lang.String';
end;
In log file ("d:\\oracle\\ora81\\network\\log\\SBE.log"), I can find message :
"Finish SBE intetraction"
but query:
select pg_sbe.call("any argument") from dual;
doesn't finish.
What can be a reason ? What can I do to trace stage of convertion java string to varchar ?
Please help me...

MarekThis comes up periodically. It just isn't possible using that type of approach. Probably the best you could do is the create an ADT (containing collections) and use that to pass a 'batch' of information.
Hopefully this will get addressed in the next release of the database. -
Recursing through table / complex return types in Java Stored Functions
I have a table representing a tree with arbitrary depth, of the form:
ID NUMBER(10) PRIMARY KEY,
NAME VARCHAR2(20),
PARENT NUMBER(10)
with PARENT being a foreign key for ID, so that top-level nodes in the tree have a NULL PARENT, and other nodes have the ID of their parent node in the PARENT field.
I want a good way to get a row representing a node as well as all its ancestor nodes recursively up to the top level. I do this a lot in my Java application, and right now it works by just getting each row, checking if PARENT is null, and recursing again until I get the top-level node. Since this recursion is in Java and I do multiple queries it's rather slow, and I'd rather perform this operation in the database (using a Java Stored Function/Procedure or PL/SQL).
I'm no good at PL/SQL so don't have a clue how to go about doing this sort of thing, and although I can write a Java Stored Function that does the same recursion I do in the application, I don't know how to return the results. I can't return a REF CURSOR type since the results are from multiple queries, and I can't find any documentation about how to return structured types from a JSF.
If anyone could give me a near-complete PL/SQL listing that does this or (better) help me to complete my Java Stored Function by returning the results in a structured type.You are my own personal God (for the day). Thanks, exactly what I needed, and all in one query with no procedural.

How to get the value retruned by java script function into my jsp page
Hai all,
I had a particular java script function which returns a date.
function getDate() {
var sDate;
// This code executes when the user clicks on a day in the calendar.
if ("TD" == event.srcElement.tagName)
// Test whether day is valid.
if ("" != event.srcElement.innerText)
//alert(event.srcElement.innerText);
sDate = document.all.year.value + "-" + document.all.month.value + "-" + event.srcElement.innerText;
document.all.ret.value = sDate;
var mahi=window.open("configurexml.jsp?xyz=document.all.ret.value")
return sDate;}
Now i want to display this particular date in my jsp page. can anyone tell me the correct approach or a sample code to diaplay this date in my jsp page.

<b>20 october 2006 </b>
Here where i am printing the date i had to get the value from the js function. how to do that. plz help me....Are you talking about server-side java code (servlets/jsp) or client side (applet)? Given we are in the JSP forum I'll assume we're talking server side.
If so, you are making a common but fundamental mistake. JavaScript executes on the client, not on the server. If you want client data on the server it has to get there somehow. The simplest way to do this in JSP land is via HTTP. So... have your JavaScript code call a JSP (or servlet) and pass the value you want as a URL parameter. Of course this will also change the browser location, so if you don't want this to happen use a frame or iframe to capture your HTTP request.
For example:
Javascript....
function someFunction() {
return 1;
var value = someFunction();
location.href="somejsp.jsp?value=" + value; -

Wrapped in a function and/or stored procedure, recursive CTE stops working
This query builds an hierarchical tree from a single table with the typical
value/reports_to_value columns.
When running in SQL manager returns like 7 records (note i'm avoiding infinite
loop by blocking top level value)
WITH c
AS
SELECT deptid, reports_to_dept
FROM glo_tree
WHERE deptid = '18538'
UNION ALL
SELECT t.deptid, t.reports_to_dept
FROM glo_tree T
INNER JOIN c
ON t.deptid = c.reports_to_dept
where t.deptid <> '00001'
SELECT deptid
FROM c
However, the exact same query, if wrapped in a function and/or stored procedure,
returns 0 records (no error message whatsoever)
CREATE FUNCTION [dbo].[checkDept] (@deptid varchar(16))
RETURNS TABLE
AS
RETURN
WITH c
AS
SELECT deptid, reports_to_dept
FROM glo_tree
WHERE deptid = @deptid
UNION ALL
SELECT t.deptid, t.reports_to_dept
FROM glo_tree T
INNER JOIN c
ON t.deptid = c.reports_to_dept
SELECT deptid
FROM c
GO
CREATE PROCEDURE [dbo].[getDept] (@deptid varchar(16))
AS
SELECT deptid
FROM dbo.checkDept(@deptid)
Then call them like:
select * FROM checkDept('18538')exec getDept @deptid='18538'
Both return nothingThanks Patrick, i don't think it can do that, i call it like:
select * FROM checkDept('18538')exec getDept @deptid='18538'Just to make sure, i've changed the function like:WHERE ltrim(rtrim(deptid)) = @deptidStill the same thing -

How to set the classpath and path from the jsp to call java class function
Hi Exprets,
I have a requirement to call a java class function which returns a hashmap object from the jsp. The java class in present in one jar file and that jar file is location somewhere in unix path. So the requirement is to set the classpath for that jar file and then create the object of the java class and then call the function.
If any one know how to achieve it, please reply as soon as possible.

swapna soni.It is never advisable to store large data sets in the session. But it will depend on a lot of factors:
1. How costly is the query retrieving the data from the database?
If it's a complex query with lots of joins and stuff, then it will be better to store it in the session as processing the query each time will take a lot of time and will decrease performance. On the other hand if the query is simple then it's advisable not to store it in the session, and fetch it each time.
2. Are there chances for the data to become stale within a session?
In this case storing the data is session will mean holding the stale data till the user session lasts which is not right.
3. How many data sets does the session already holds?
If there are large no. of data sets already present in the session, then it's strictly not advisable to store the data in the session.
4. Does the server employ some kind of caching mechanism?
Using session cache can definitely improve performance.
You will have to figure out, what is the best way analyzing all the factors and which would be best in the situation. As per my knowledge, session is the only place where session specific data can be stored.
Also, another thing, if the data set retrieved is some kind of data to be displayed in reports, then it would be better to use a pagination query, which will retrieve only the specific no. of rows at a time. A navigation provided in the UI will retrieve the next/previous data set to display.
Thanks,

Wrong value in java stored function
Hi All,
i have written a java stored function,
at the end of the code it insert record into the database
among other columns also a number(18,3) column,
when I debug it (out side of server) - works fine.
when I load it to database i get wrong values in column
(like instead of 76.546 i get 77.667) I can't figure out where it comes from.
I use big decimal in java code.
if i Hard code the value in java code it works fine!
am I missing something ?, calculations/ data type different out side then inside database? using oracle 10.2.0.2
Cheers
SaharHi
the code calculate some averages of amounts ( money) according to several
conditions,and parameters given to the function and stores the average into table in the database
the money columns are of data type 18,3 , both source and target tables have same structure.
thanks

2. Can u please check this code and refer me a solution for Calling this function
create or replace function NewTest (iEN Integer)
return sys_refcursor
as
rc sys_refcursor;
begin
open rc for select * from Scott.Emp Where EmpNo=iEN;
return rc;
