How to call a java function that is in page header from a process in page.
Hi,
Generally we call plsql process from a javascript in the header of that page.
But i want the other way around.
Is it possible or is it a completely wrong idea.
I am thinking so because we are able to call javascripts from items and buttons why cant we do so from a process.
Thanks and Regards,

I am thinking so because we are able to call javascripts from items and buttons why cant we do so from a process.It's a "completely wrong idea". Processes and PL/SQL run in the database on the server. JavaScript runs in the browser on the client. For basuic security reasons the browser must make requests to the server, not the other way round.

How to call a Stored Function with OUT parameter of %rowType from Java
Hi everyone,
I'm getting crazy trying to make this work.
I have a function (not developed by me) in Oracle 10g declared in this way:
type tab_RLSSP is table of TB_RLSSP_STOSTPRPAR_CL%ROWTYPE index by binary_integer;
FUNCTION DBF_PERL_LISTA_PRATICHE (
p_id_va IN NUMBER,
p_seq_partita IN NUMBER,
p_trattamento IN CHAR,
lrec_RLSSP OUT tab_RLSSP ) RETURN NUMBER;
And here is the code snipplet of my java method:
sql="{? = call "+SCHEMA+PACKAGE+"."+FUNCTION_LIST+"(?,?,?,?)}";
cs=connection.prepareCall(sql);
cs.registerOutParameter(1, OracleTypes.NUMBER);
cs.setLong(2,idVATitolare);
cs.setLong(3,seqPartita);
cs.setString(4,trattamento);// Caso Decesso
cs.registerOutParameter(5, OracleTypes.OTHER);
cs.executeQuery();
result = (ResultSet) cs.getObject(5);
if (result.next())
listaPratiche.add(readPraticaPartita(result));
The result (exception thrown at executeQuery with statement generated as
SQL : {? = call PEDBA.DBK_PERL_RATEI_SUPPLETIVI.DBF_PERL_LISTA_PRATICHE(?,?,?,?)}:
java.sql.SQLException: ORA-06550: line 1, column 13:
PLS-00306: wrong number or types of arguments in call to 'DBF_PERL_LISTA_PRATICHE'
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored
Changing to :
sql="{call ? := "+SCHEMA+PACKAGE+"."+FUNCTION_LISTA+"(?,?,?,?)}";
leading to
SQL : {call ? := call PEDBA.DBK_PERL_RATEI_SUPPLETIVI.DBF_PERL_LISTA_PRATICHE(?,?,?,?)}
don't change anything.
What's wrong? Any suggestion?

Taking for granted that it works, I wonder what's different, probably the output is defined as Cursor...
>
You mean because of this line?
cs.registerOutParameter(5,OracleTypes.CURSOR);You can either use a cursor or use a function that returns a SQL type instead of the PL/SQL type.
Here is sample code using a cursor
CREATE OR REPLACE TYPE SCOTT.local_type IS OBJECT (
empno NUMBER(4),
ename VARCHAR2(10));
CREATE OR REPLACE TYPE SCOTT.local_tab_type IS TABLE OF local_type;
CREATE OR REPLACE PACKAGE SCOTT.test_refcursor_pkg
AS
TYPE my_ref_cursor IS REF CURSOR;
-- add more cursors as OUT parameters
PROCEDURE test_proc(p_ref_cur_out OUT test_refcursor_pkg.my_ref_cursor);
END test_refcursor_pkg;
CREATE OR REPLACE PACKAGE BODY SCOTT.test_refcursor_pkg
AS
PROCEDURE test_proc(p_ref_cur_out OUT test_refcursor_pkg.my_ref_cursor)
AS
l_recs local_tab_type;
BEGIN
-- Get the records to modify individually.
SELECT local_type(empno, ename) BULK COLLECT INTO l_recs
FROM EMP;
-- Perform some complex calculation for each row.
FOR i IN l_recs.FIRST .. l_recs.LAST
LOOP
DBMS_OUTPUT.PUT_LINE(l_recs(i).ename);
END LOOP;
-- Put the modified records back into the ref cursor for output.
OPEN p_ref_cur_out FOR
SELECT * from TABLE(l_recs);
-- open more ref cursors here before returning
END test_proc;
END;
SET SERVEROUTPUT ON SIZE 1000000
DECLARE
l_cursor test_refcursor_pkg.my_ref_cursor;
l_ename emp.ename%TYPE;
l_empno emp.empno%TYPE;
BEGIN
test_refcursor_pkg.test_proc (l_cursor);
LOOP
FETCH l_cursor
INTO l_empno, l_ename;
EXIT WHEN l_cursor%NOTFOUND;
DBMS_OUTPUT.PUT_LINE(l_ename || ' | ' || l_empno);
END LOOP;
CLOSE l_cursor;
END;

Thanks for any help in advance!
NielsI would suggest putting the calls to WorkDocumentWsStub.new and WorkDocumentWsStub.searchDocuments(jo,jo1) in separate exception blocks so you know which one generates the nullpointerexception.
Also, shouldn't you provide parameters to the "new" function? What should the searchDocuments function search for then? There is no document after all. -
This is happening with an ASP page. Not sure when it started, but the page used to work fine. The Java script is listed in the troubleshooting section. The button calls nextPic() which calls showPic(). After nextPic processes the page is reloaded.

JavaFX : How to call java function that returns hashtable and manipulate
I have a requirement to {color:#0000ff}create a java object in JavaFX script code{color}. Then call a java function using the created java object. The java function returns hashtable. Then traverse through each element of hashtable. Finally I need to create a similar structure in JavaFX.
If you need to use a Java class that uses generics you need to take special steps. Since JavaFX does not support generics you need to create a java wrapper to hide the calls that use generics and call the wrapper class from FX.

How to call a php function from java...
helllo fellow java developers!
Im trying to figure out how I can call a php function from my java code.
I know it sounds a bit unintiutive, seeing how java is a rich programming language, BUT java simply cannot do the task that the php script can do. It simply acts differently.
So I am trying to call a php function, that returns a string object, and capture that string object....
is this possible?
something like....
String strMyString = phpFunction( strVariable )
???????/ any ideaS?idea #1 - come up with a better plan that doesn't involve invoking php from java.
Give one example of something php can do that java can't.
idea #2 - forget java, and just write it in php.
Involving multiple frameworks/languages/runtime environments is a recipe for an overcomplicated solution that will be impossible to maintain.
I'd say keep it simple and stupid, and stick with one language.
If you're still hooked on the idea, maybe try [this link|http://www.infoq.com/news/2007/10/php-java-stack] -
How to make a Java program that recognises a function of two variables...
How to make a Java program that recognises a function of two variables to assign values to that?
First I will give an example and then do the question.
Ex1.
We have any function, eg.y = x ^ 2 + 1 (read 'y' equals 'x' high to the square), a function of the second degree.
To build the graph of this function attach values to 'x' to find the values of 'y'
And thus mount the pair ordered (x, y) which represents a point on the Cartesian plane.
Assigning values to 'x' 'we can build up a table that gives us the pairs ordered:
We can use any numbers, but arfer interval [-3.3]
X | y = x ^ 2 + 1
-3 | Y = (-3) ^ 2 +1 = 10
-2 | Y = (-2) ^ 2 +1 = 5
-1 | Y = (-1) ^ 2 +1 = 2
0 | y = (0) ^ 2 +1 = 1
1 | y = (1) ^ 2 +1 = 2
2 | y = (2) ^ 2 +1 = 5
3 | y = (3) ^ 2 +1 = 10
We then ordered the pairs:
(-3.10), (-2.5); (-1.2), (0,1), (1,2), (2,5), (3,10)
Tabem that can be represented by a table:
X | y
-3 | Y = 10
-2 | Y = 5
-1 | Y = 2
0 | y = 1
1 | y = 2
2 | y = 5
3 | y = 10
Now I begin to explain my doubts.
See this program:
Ex2
* To change this template, choose Tools | Templates
* And open the template in the editor.
Encontrando_o_valor_de_y package;
* @ Author des Soldat Gottes
Import javax.swing.JOptionPane;
Public class (Main
* @ Param args the command line arguments
Public static void main (String [] args) (
Int x, y;
String x1;
X1 = JOptionPane.showInputDialog ( "We have the function y = x + 1 \ n" +
"Assign a value for 'x',"); / / receives a value for the function y = x + 1
X = Integer.parseInt (x1); / / tranforma String in int
Y = x + 1; / / receives the value of 'x' and calculates' y '
JOptionPane.showMessageDialog (null, "The value of 'y' is: \ t \ t" + y);
/ / Displays the value of 'y'
System.exit (0);
We see that the program receives above a value for 'x' and replaces the function contained in the program, y = x + 1, and so is the value of the variable 'y'.
In: x1 = JOptionPane.showInputDialog ( "We have the function y = x + 1 \ n" +
"Assign a value for 'x',");
The entry is a number and that number is assigned aa ja existing function in the (y = x + 1).
The question is: would it be possible to come to a function?
Ex: the program ask: DIGITE THE FUNCTION?
The USUARIO DIGITARIA A FUNCTION ANY, TYPE: y = x ^ 2 +1
The program would recognize the function and give numerical values to that function as Ex1, at the beginning of this text.
And then to find the values of the x and y launch a table.
It would be possible that?
By invez of entering with a number so that the program sustitua a function ja existing as Ex2, seen above, entering with a function quaquer (type: y = x ^ 2 +1) for the program atribuisse values to that function and then create a table of values as Ex1.
I hope it has been easier to understand my doubts now.
Thank you for your attention!

Thanks for the explanation, could understand what fly said.
But as it applied to a program?
How to create a program that recognizes that the entry coefficients?Are you asking about how to parse out the coefficients from the string "3x^4 + 4x^3 - 8x^2 + 5x^1 + 2x^0"? If you define the format to strictly follow that example, this should get you started:
Strip out the spaces
Split the String on "x^"
That should give you [3, 4+4, 3-8, 2+5, 1+2, 0]
Split each resulting String on "+ | -", preserving the operator as a token so you can apply the correct sign to the coeff.
That should leave you with [3, 4, +, 4, 3, -, 8, 2, +, 5, 1, +, 2, 0]. Every other number is a coeff, the rest are the degrees.
You can strip out the +, since those coeffs are already positive, and strip out the - after negating the following number. This is all assuming that you have to write this yourself. There is no doubt already a library or 5 out there that does this for you. -
Calling a java function from xquery
Hello,
I'm pretty new to ODSI and xquery, so forgive me if what I'm asking is too trivial, but I need to find a way to call a java function from inside xquery. I know xquery can do this through external functions, but can't find any example on how the query prolog declaration should be, nor how the function should look like. Could someone enlighten me?
Thanks,
Pedro IvoYou can do this 2 ways that I know of (Mike probably has more ideas too)
1. Register an inversion function:
[How to use an inversion function|http://download.oracle.com/docs/cd/E13167_01/aldsp/docs32/dsp32wiki/Using%20Inverse%20Functions%20to%20Improve%20Query%20Performance.html]
2. Create a physical data service based on a java function. I have used this approach for both custom JDBC database operations and straight Java processing, with pretty good results.
Good luck,
Jeff

Call a Java Function From Abap
Hi, I need to call a java function from ABAP, I have a WAS 640 to deploy the module.
I have found this tutorial...
[ABAP calls Java via RFC|/people/thorsten.franz3/blog/2008/11/21/abap-calls-java-via-rfc-1-introduction]
The problem is that it uses a newer version of WAS and it implements EJB 3.0 wich only works on Java 5, but my WAS has java 1.4.2.
Anyone knows how to adapt this Blog to a WAS 640 version ?
Or Perhaps there is another way of doing this, maybe publishing my function as a web service.
Regards.
Mariano.Why don't you expose your Java functionality as a Web Service and consume it in ABAP program. That should be much easier and the web service can be used in other places as well.
Best regards,

How to call a SQL function from an XSL expression
Hi
In R12, in Payroll Deposit adivce/Check writer, We need to sort the earnings tag <AC_Earnings> in to two different categories as regular and other earnings. In the DB and form level of element defintiion we have a DFF which differentiates between the two kinds of earnings. But the seeded XML that is gerneated by the check writer does not have this field.
The seeded template displays all the earnings in one column. How can we achieve this in the template without modifying the seeded XML.
The one approach i have is to write a function and based on the return value sort the data. For this I need to know :

you just need to create an object of that class,thats it. Then you will be able to execute each and every method.
e.g.
you have developed A.java and B.java, both are in same package.
in implementaion of B.java
class B
A obj = new A();
//to access A's methods
A.method();
// to access A's variable
//either
A.variable= value.
//or
A.setvariable() or A.getvariable() -
