Access variables in Package.

Hi I have a apackage called share.server , in which I have defined
Hashtable hash;
i have another file in share package as Impl, here i want to call the "hash"
how can i access the same "hash" in Impl.java from FilServer which is in share.server package.
Please respond urgent, assignment is due soon.
Thanks for any response.

what?!
variables belong to classes, not packages. If you want to access variables between classes you need to define some kind of public interface for them (getters and setters... ring any bells?). This is basic basic OOP, and is called encapsulation. First thing you need to do is get a basic 'OOP with java' type book and read it fully. We can't help you if you can't help yourself/

ORA-20001: Unauthorized access (security group package variable not set).

I'm creating an app that uses APEX authentication and features self-registration (working) and forgot password (not working) forms.
My forgot password is public (requires no authentication). The user provides username and secret answer, which are validated, then provides the new password. I attempt to use htmldb_util.reset_pw to reset the user's password, but it's not working.
I have a process on the new password page calling a PL/SQL anonymous block that looks like this (see below), where P16_ITEM1 = username and P18_ITEM1 = new password.
BEGIN
apex_040000.htmldb_util.reset_pw( V('P16_ITEM1'), V('P18_ITEM1') );
END;
I also don't know how to send accurate success/failure messages from such PL/SQL block back to APEX, but that's a separate issue I guess.
Anyway, when testing via SQL Developer as the user with APEX_ADMINISTRATOR_ROLE, I get the following error:
ORA-20001: Unauthorized access (security group package variable not set).
ORA-06512: at "APEX_040000.WWV_FLOW_FND_USER_API", line 22
ORA-06512: at "APEX_040000.WWV_FLOW_FND_USER_API", line 1220
ORA-06512: at "APEX_040000.HTMLDB_UTIL", line 1253
ORA-06512: at line 8
I've searched previous threads and tried different suggestions with no luck.
I'm on Oracle DB XE 11g and APEX 4.x.
Any help will be appreciated. Thanks,
Alex.

Anyway, when testing via SQL Developer as the user with APEX_ADMINISTRATOR_ROLE, I get the following error:
ORA-20001: Unauthorized access (security group package variable not set).When running code outside Apex that depends on the Apex security group being set, run the following before your own code:
wwv_flow_api.set_security_group_id(apex_util.find_security_group_id('YOUR_SCHEMA_NAME'));Google "wwv_flow_api.set_security_group_id" for more details, such as this blog post:

How do I use bin variable in package without asking a user?

hi,
I would like to write an SQL but I want to use bind variable in package as a static without asking user? Like below?
I would like to ask you, below there is a emp_id variable? Is this BIND variable?
DECLARE
bonus NUMBER(8,2);
emp_id NUMBER(6) := 100;
BEGIN
SELECT salary * 0.10 INTO bonus FROM employees
WHERE employee_id = emp_id;
END;
If not, like this SQL how can define a BIND variable as static inside a code? not asking a user?
db version. 9.2.0.8
regards and thanks

/In the query "SELECT salary * 0.10 INTO bonus FROM employees WHERE employee_id = emp_id" emp_id is turned into a bind variable because
if you are coding static SQL in PL/SQL then PL/SQL wil automatically use bind variables: please read http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14261/overview.htm#sthref145.
This can also be proved with SQL trace. The following code:
alter session set sql_trace=true;
declare
v number;
c number;
begin
select count(*) into c
from t
where x=v;
end;
show errors
alter session set sql_trace=false;generates following raw trace file section with 10G XE:

How to access variables outside user exit

Hi,
I'm working with a user exit and my problem is that in a particular moment I have to access variables located outside the scope of the user exit (they are in a standard program)
How can I reach these variables?
thanks in advance

Hi,
If they are global variables then you can access them using Global assign technique,
For example,
FIELD-SYMBOLS: <fs_value> TYPE ANY.
ASSIGN ('(SAPMV45A)XVBAK') TO <fs_value>.
It is basically,
ASSIGN ('(<Std. Program Name>)<Variable name>') TO <field symbol>.
NOTE: To make sure they are accessible in your user exit, just put a break-point in the user exit and once you are there in debugging, type in,
(<Std. Program Name>)<Variable name> in the Field names section and if it does not show it in RED then it is accessible..
Hope this helps..

How to Access Variables defined in the PopUpWindow

Hi Friends
I am building a flex site using flex builder 2.....

but this variable is not accessible from the loginwidow.mxml page
where the popup will function...
Heip me
how to store the name if the user login is success..

Lets say you have a public property in your application like
public var name:String = "John Smith";
to access this using an inline item renderer:
<mx:itemRenderer>
<mx:Component>
<mx:VBox>
<mx:TextInput text={outerDocument.name} />
</mx:VBox>
</mx:Component>
</mx:itemRenderer>
To access variables of the applicaton you can use
Application.application.name (for example) to reference "global"
variables, so you might also use this technique. With an inline
item renderer, the outerDocument property will refer to the
component which contains the renderer.

Global Variable in Package Specification

Hello,
I created global variable in package specification,
Is it valid for the current session or it will work for all the session.
Thanks,Kannan.K

Package varaibles are session bound, to demonstrate, a simple test:
--session 1:
SQL> select dt_test_pack.get_global from dual;
GET_GLOBAL
SQL> exec dt_test_pack.set_global(50);
PL/SQL procedure successfully completed.
SQL> select dt_test_pack.get_global from dual;
GET_GLOBAL
        50
--Session 2 at the same time
SQL> select dt_test_pack.get_global from dual;
GET_GLOBAL
SQL> exec dt_test_pack.set_global(100);
PL/SQL procedure successfully completed.
SQL> select dt_test_pack.get_global from dual;
GET_GLOBAL
       100
--Back to session 1:
SQL> exec dt_test_pack.set_global(null);
PL/SQL procedure successfully completed.
SQL> select dt_test_pack.get_global from dual;
GET_GLOBAL
--Back to session 2:
SQL> select dt_test_pack.get_global from dual;
GET_GLOBAL

Can't access variables in specific S7-1200 DB's in LabVIEW project

Hi all,
I'm trying to establish a connection between LabVIEW and a Siemens S7-1200 though Ethernet and SIemens OPC Server.
The physical connection is OK (I can ping S7-1200 with no problem).
When I needed to access variables from specifics DB's inside S7-1200 ( I want to access variable DB190,X0.4), I called Siemens support and they said I had to modify the variable's definition when using OPC Scout, from "MX0.4" to "DB190,X0.4", and then it was possible to access this variable.
Same solution (renaming the path) applies to NI OPC Client, I can read and write variables properly.
My problem is that when I try to add variables in LabVIEW Project, I can't find those variables whose address were modified, so I can't access the correct variable in my program.
I tried to change the variable path in Multiple Variable Editor, but it doesn't work either.
Any suggestions on what I can try??

First: Avoid the ODBC/JDBC Bridge if at all possible.
It's the worst JDBC driver I've ever seen. It's buggy
and a great hindrance both to learning and to
producing usefull code.I agree that there might be problems with M$ Access, but there are problems with all databases, including MySQL (e.g., no referential integrity in free download version). It's capable enough for the query the OP is trying to execute.
The problem is with his code, not Access or the bridge driver. He'll go through a lot of effort to switch databases and still have this problem. Better to understand what HE'S done wrong and fix it so he'll do it correctly for all databases, including Access.
You just need to be more careful with your query, I'm sure.

Reuse Variable In Packages

I have a scenario where I need to reuse the variable in several packages without refreshing it. For example I have package 1, 2 and 3. I have defined a variable var_timestamp with latest value and declare this variable in package 3, I have generated scenario of package 1 and 2 and insert it in package 3. I refresh the variable as first step and reuse the variable in package 1 and 2 without refreshing it but var_timestamp value is not recognized in package 1 and 2.I didn't declare these variable in package 1 and 2 as I dont want it to be refresh again. I have tried Not Persistant variable as well but it didn't work. Any clue how can we reuse the variable without refreshing it in different packages.
Thanks
Kash

When you use a variable in a package it is important to declare it
Use the variable as Latest Value
Dont use the Historize or Persistent
If you have declared and refreshed it in package 3.......there might be 2 steps right?
1st step as declare and another step as refresh
In your packages 1 & 2, you should make a step as declare variable only, where you should drag your variable in the package and make it a declare variable step
And re-generate the scenario to be able to get the effect of this change in your scenario
Let me know in case you face any difficulties

Access variables within a timer

How can I access variables within a timer?
I mean variables, that I can use in another class that extends applet i.e.?

The Code can be compiled now with the Java Compiler.
But the image won't move on the screen.

Passing Record Variable through Packages

I have a question and hope that someone can help me to find the solution.
I'm developing an application and I need to pass values form one procedure PR in package B to a function FN in package A. The why I try to go is passing the values by using a variable of record type.
I have defined in both packages the same record structure that I also use in the declarations of procedure and function. I first compiled successfully the package A but when I try to compile the package B I get a compilation error:
PLS-00306: wrong number or types of arguments in call to 'B.FN'
It looks like the parameter definition or reference gets lost.
Here below a very schematic example of my application:
create or replace package A is
type Rec1 is record
( rf1 T.f1%type,
rf2 T.f2%type,
rf3 T.f3%type)
function FN ( Par in Rec1 ) return boolean;
end;
create or replace package A is
function FN ( Par in Rec1 ) return boolean is
V_ret boolean;
begin
whatever it does
return V_ret ;
end;
end;
create or replace package B is
type Rec1 is record
( rf1 T.f1%type,
rf2 T.f2%type,
rf3 T.f3%type)
procedure PR ( Par in Rec1 ) return boolean;
end;
create or replace package B is
procedure PR ( Par in Rec1 ) is
VP Rec1;
V_go boolean;
begin
VP.rf1:= something_1;
VP.rf2:= something;
VP.rf3:= something;
V_go:=FN ( VP ); <= here the compiler complaints
whatever it does
end;
end;
Many thanks for a quick answer.

Okay I didn't notice the error message text in the body of the paragraph above.
PS. If I specify singularly the fields in the parameter list I pass the compilation
but I would like to use a record variable as one.Did you see my post where I always reference the record variable in package A?
create or replace package B is
procedure PR ( Par in A.Rec1 ) return boolean;
end;
create or replace package B is
procedure PR ( Par in A.Rec1 ) is
VP A.Rec1;
V_go boolean;
begin
VP.rf1:= something_1;
VP.rf2:= something;
VP.rf3:= something;
V_go:=A.FN ( VP ); <= here the compiler complaintsIt should work.

Console.WriteLine(" TASKS");
for (Int32 tsk = 1; tsk <= pkg.Tasks.Count; tsk++)
if (pkg.Tasks.Item(tsk).CustomTaskID == "DTSDataPumpTask")
dataPumpTask = (DTS.DataPumpTask2)pkg.Tasks.Item(tsk).CustomTask;
Console.WriteLine(" TRANSFORMS");
for (Int32 trans = 1; trans <= dataPumpTask.Transformations.Count; trans++)
transform = dataPumpTask.Transformations.Item(trans);
for (Int32 col = 1; col <= transform.SourceColumns.Count && col <= transform.DestinationColumns.Count; col++)
source = transform.SourceColumns.Item(col);
destination = transform.DestinationColumns.Item(col);
Console.WriteLine(" {0} -> {1}", source.Name.PadRight(15, ' '), destination.Name);
