How to return data from message bean ? ? ?

Hi ... I have developed one simple application in JMS ...
I have created one jsp page, one message bean and one remote EJB ...
Now i m sending message to message bean .... i m also receiving message in message bean and i m calling one simple EJB method on that message called ...
This all things are working well. But i wanted to return some data from that EJB to my JSP page .
for example ...
there is one sayHello() method in EJB which i m calling from message bean as i got message from JSP page .
if i m printing that string in server log than its working well .
now i wanted to return that string from that EJB method to JSP page.
How can i achieve this ? can any one help me please ...
actually i wanted to return whole XML file but recently as a newbie i m trying to just return hello world string .
please help me for this problem ....
thnks ...

if you want to return a result, then you probably shouldn't be using a message bean. message beans for for asynchronous tasks. session beans for for synchronous tasks. thus it would make much more sense to have your jsp call the session bean directly.

How to return data from Ejb as collection to Front End application.

Hi,
I am creating a J2ee application. Here i am accessing BAPIs using stateless session bean through JCO connection. Now the BAPI is returning a return Table and return Structure to the EJB.
I have coded the following code in one of the Ejb Method as follows:
JCO.Table returnTable = null;
JCO.Structure returnStructure = null;
JCO.ParameterList paramList = siteBAPI.getExportParameterList();
JCO.ParameterList paramList2 = siteBAPI.getTableParameterList();
returnTable = paramList2.getTable("SITE_SUBSITE_INSTL");
returnStructure = paramList.getStructure("BAPIRET2");
Now i want to sent this data( returnTable & returnStructure) to front end application where front end developer accessing this returned data using Jsp.
My scenario is that , first i want to convert this returnTable & returnStructure in a single collection and then sent this collection to Front end.
My aim is that , the front end the application should not receive the Data, using JCO.table Variable but as a single Collection.
I am using NWDI-2004s sps10.
i need urgent help on this issue and i would really appreciate if somebody can put the answer with some sample code on how to return the data as Collection.

if you want to return a result, then you probably shouldn't be using a message bean. message beans for for asynchronous tasks. session beans for for synchronous tasks. thus it would make much more sense to have your jsp call the session bean directly.

2 Threads issues. How to return data from a thread located in other class

I have 2 questions.
This is the context. From main I start one thread that does a little job then starts another thread and waits for it to end to continue.
1) The last started thread needs to return a string to the Thread started from main. How can I accomplish that, because I read that I cannot use
synchronized methods outside different classes (and the threads belongs to different classes).
2) From the main thread I start the Second Thread located in another class like this ClassName obj = new ClassName(arg); obj.start(); obj.join()
Is that correct for waiting for the created thread to finish ?

1) The last started thread needs to return a string to the Thread started from main. How can I accomplish that, because I read that I cannot use
synchronized methods outside different classes (and the threads belongs to different classes).Threads do not "belong" to classes. Class code executes in a particular thread. The class instances exist as long as something, somewhere, holds a strong reference to them.
So when you start a new thread, hold a strong reference to the object being executed by that thread. When the thread is done, retrieve your data from that object.
Even better, don't subclass Thread to create your objects. Instead, implement Callable, and use a ThreadPoolExecutor to execute it.

Return data from spark list itemrenderer

Does anybody no how to return data from the itemrender for a spark list. say i had a checkbx in my itemrenderer how can I get that info back to my main component if its selected or not. I looked at datagrid and itemeditor but I really rather use a spark list. Thanks

thanks I also found another way to doing it. A click handler on my list when that fires I can check if checkbx has been selected by doing event.target.document.mycheckBx.selected this will not work if using currentTarget cause it take the info from the itemRenderer. Now I understand the difference between currentTarget and target.
not sure if this is a better way to access the data I think I might still just dispatch a event and do it your way.
Its weird that mx:list has a editItemRenderer and s:list does not
thanks again TK

Return data from Java servlet in form of JSON encoded parameters in Javascr

How to return data from Java servlet in form of JSON encoded parameters in Javascript handler function call?
The same is implemented in php as the following
echo "sT.handleAjaxResponse(";
echo json_encode($response);
echo ");";
How to do the same in Java servlet?
Thanks.

With the rising popularity of JSON (especially with Ajax), support for it has started to appear in the Java community. I am not aware of any standardized approach yet, but expect it is likely we'll see that eventually. For now, you probably want to look at a third-party library such as the [JSON in Java Library|http://www.json.org/java/], Jettison, or [Java Tools for the JSON Format|http://jsontools.berlios.de/].

How configure a primavera web service to return data from the second database?

Hi everyone,
We have P6 with first WS deployed on a single server weblogic domain. The first WS return data from the first database instance.
Then deployed advanced second WS on a separate weblogic domain server with a different port. Configured second WS with <WS2_INSTALL_HOME>/bin/dbconfig.sh, creating a new branch of a configuration that specifies a different second instance of the database. However, this configuration is ignored and second web services return data from the first database.
We have one domain, which including next servers:
Name / Host / Port / Deployments
P6 / localhost / 0001 / P6(v8.3), p6ws1(v8.3)
p6ws2 / localhost / 0002 / p6ws2(v8.3)
Now we have two different file BREBootstrap.xml.
P6 BREBootstrap.xml:
<Database>

OK, so I got this to work this morning with Username Token Profile (with little help from Oracle Support).
I followed your steps 1-4 but in step 2 I didn't add the -Ddatabase.instance=2 because I want to check to see if my code could swap between different instances.
It appears for Username Token Profile to use Database Instance, you need to set it in the soap header.

How to pass data from one internal session to another internal session

hi all sap experts ,
How to pass data from one internal session to another internal session and from oneExternal session to another external session.
Except : Import and Export parameters and SPA/GPA parameters.
Tell me the otherWay to pass data ..
Plz
Thanks in advance

hi,
abap memory management u will understand about this concept.
the import /export parameter will help u that passing data between two internal sessions by using abap memory.
for syntax
Passing Data Between Programs
There are two ways of passing data to a called program:
Passing Data Using Internal Memory Areas
There are two cross-program memory areas to which ABAP programs have access (refer to the diagram in Memory Structures of an ABAP Program) that you can use to pass data between programs.
SAP Memory
SAP memory is a memory area to which all main sessions within a SAPgui have access. You can use SAP memory either to pass data from one program to another within a session, or to pass data from one session to another. Application programs that use SAP memory must do so using SPA/GPA parameters (also known as SET/GET parameters). These parameters can be set either for a particular user or for a particular program using the SET PARAMETER statement. Other ABAP programs can then retrieve the set parameters using the GET PARAMETER statement. The most frequent use of SPA/GPA parameters is to fill input fields on screens (see below).
ABAP Memory
ABAP memory is a memory area that all ABAP programs within the same internal session can access using the EXPORT and IMPORT statements. Data within this area remains intact during a whole sequence of program calls. To pass data to a program which you are calling, the data needs to be placed in ABAP memory before the call is made. The internal session of the called program then replaces that of the calling program. The program called can then read from the ABAP memory. If control is then returned to the program which made the initial call, the same process operates in reverse. For further information, refer to Data Clusters in ABAP Memory.
Filling Input Fields on an Initial Screen
Most programs that you call from other programs have their own initial screen that the user must fill with values. For an executable program, this is normally the selection screen. The SUBMIT statement has a series of additions that you can use to fill the input fields of the called program:
Filling the Selection Screen of a Called Program
You cannot fill the input fields of a screen using additions in the calling statement. Instead, you can use SPA/GPA parameters. For further information, refer to Filling an Initial Screen Using SPA/GPA Parameters.

How to pass data from one internal session to another

Memory Structures of an ABAP Program
In the Overview of the R/3 Basis System you have seen that each user can open up to six R/3 windows in a single SAPgui session. Each of these windows corresponds to a session on the application server with its own area of shared memory.
The first application program that you start in a session opens an internal session within the main session. The internal session has a memory area that contains the ABAP program and its associated data. When the program calls external routines (methods, subroutines or function modules) their main program and working data are also loaded into the memory area of the internal session.
Only one internal session is ever active. If the active application program calls a further application program, the system opens another internal session. Here, there are two possible cases: If the second program does not return control to the calling program when it has finished running, the called program replaces the calling program in the internal session. The contents of the memory of the calling program are deleted. If the second program does return control to the calling program when it has finished running, the session of the called program is not deleted. Instead, it becomes inactive, and its memory contents are placed on a stack.
The memory area of each session contains an area called ABAP memory. ABAP memory is available to all internal sessions. ABAP programs can use the EXPORT and IMPORT statements to access it. Data within this area remains intact during a whole sequence of program calls. To pass data to a program which you are calling, the data needs to be placed in ABAP memory before the call is made. The internal session of the called program then replaces that of the calling program. The program called can then read from the ABAP memory. If control is then returned to the program which made the initial call, the same process operates in reverse.
All ABAP programs can also access the SAP memory. This is a memory area to which all sessions within a SAPgui have access. You can use SAP memory either to pass data from one program to another within a session, or to pass data from one session to another. Application programs that use SAP memory must do so using SPA/GPA parameters (also known as SET/GET parameters). These parameters are often used to preassign values to input fields. You can set them individually for users, or globally according to the flow of an application program. SAP memory is the only connection between the different sessions within a SAPgui.
The following diagram shows how an application program accesses the different areas within shared memory:
In the diagram, an ABAP program is active in the second internal session of the first main session. It can access the memory of its own internal session, ABAP memory and SAP memory. The program in the first internal session has called the program which is currently active, and its own data is currently inactive on the stack. If the program currently active calls another program but will itself carry on once that program has finished running, the new program will be activated in a third internal session.
Data Clusters in ABAP Memory
You can store data clusters in ABAP memory. ABAP memory is a memory area within the internal session (roll area) of an ABAP program and any other program called from it using CALL TRANSACTION or SUBMIT.
ABAP memory is independent of the ABAP program or program module from which it was generated. In other words, an object saved in ABAP memory can be read from any other ABAP program in the same call chain. ABAP memory is not the same as the cross-transaction global SAP memory. For further information, refer to Passing Data Between Programs.
This allows you to pass data from one module to another over several levels of the program hierarchy. For example, you can pass data
From an executable program (report) to another executable program called using SUBMIT.
From a transaction to an executable program (report).
Between dialog modules.
From a program to a function module.
and so on.
The contents of the memory are released when you leave the transaction.
To save data objects in ABAP memory, use the statement EXPORT TO MEMORY.
Saving Data Objects in Memory
To read data objects from memory, use the statement IMPORT FROM MEMORY.
Reading Data Objects from Memory
To delete data clusters from memory, use the statement FREE MEMORY.
Deleting Data Clusters from Memory

Return data from all columns apart from a certain data type.

Bit stuck on something, hope somebody here can help:
I want to do a 'select * from ' a table, to return all columns except ones of a certain datatype. ie. I want to return data from all columns, excluding columns of datatype 'SDO_GEOMETRY'.
This gives me the list of columns:
SELECT COLUMN_NAME
FROM USER_TAB_COLUMNS
WHERE TABLE_NAME = 'ORDER_ITEM'
AND DATA_TYPE <> 'SDO_GEOMETRY'; But I can't seem to take it any further...
Now if I knew the columns beforehand, then of course I could just list them, excluding the geometry column, but this is to be used for a plug-in for MS Word, where a user can pick database columns to dynamically fill a report from - but I don't want the geometry columns as these can't be handled in this way.

Hi Reggie,
> connects to the database and presents a list of tables
My guess is that this macro is written so it selects from all_tab_cols.
Change that plugin and let it select from a view like the one above. That way, the users won't be able to see/pick anything that you are not able/willing to present for them.
Edit:
You could even tease your users, and let them see the columns, but not being able to pick them.
create or replace view available_tab_columns
as
 select decode(pickable.data_type, null, 0, 1) pickable
 ,atc.* -- narrow down yourself
 from all_tab_cols atc -- or maybe user_tab_cols
 ,(select 'CHAR' data_type from dual union all
 select 'DATE' from dual union all
 select 'NUMBER' from dual
 -- complete positive list, yourself
 ) pickable
 where atc.data_type = pickable.data_type(+);Regards

Hi, I know there are three ways to pass out a value from a Microsoft SQL stored procedure, but I have no clear idea what Oracle SP can do, I know Oracle doesn't support multi-recordset(v8), can not return a recordset by a inner select query, but I do know there is a cursor object, which doesn't like its counterpart in Microsoft SQL server, is a choice under most situation. Here I wonder anyone who is good at Oracle can give a list of all ways to return data from a SP, including example is more better, thanks.

Here is a way to get return a record from a function and a procedure. You need to be familiar with Oracle packages as well as stored procedures and functions:
CREATE OR REPLACE PACKAGE EmpPkg AS
cursor cEmp(pEmpno in number) is
select empno, ename, job, hiredate, sal
from emp
where empno = pEmpno;
FUNCTION GetEmployee(pnEmpNo in number) RETURN cEmp%rowtype;
PROCEDURE GetEmployee(pnEmpNo in number, prEmp out cEmp%rowtype);
END;
CREATE OR REPLACE PACKAGE BODY EmpPkg AS
FUNCTION GetEmployee(pnEmpNo in number) RETURN cEmp%rowtype IS
rEmp cEmp%rowtype;
BEGIN
open cEmp(pnEmpNo);
fetch cEmp into rEmp;
close cEmp;
return rEmp;
END;
PROCEDURE GetEmployee(pnEmpNo in number, prEmp out cEmp%rowtype) IS
BEGIN
open cEmp(pnEmpNo);
fetch cEmp into prEmp;
close cEmp;
END;
END;
Here's how you use the package:
DECLARE
rEmp EmpPkg.cEmp%rowtype;
BEGIN
rEmp := EmpPkg.GetEmployee(7782);
dbms_output.put_line(rEmp.ename);
EmpPkg.GetEmployee(7902, rEmp);
dbms_output.put_line(rEmp.ename);
END;
Note that you can return any Oracle data type from a function. Likewise, you can specify any Oracle data type as an out parameter in a procedure. Also, you can make a parameter both an in and an out datatype like this:
PROCEDURE GetEmployee(pnEmpNo in out number);
I hope this puts you in the right direction.
