Get username from session and retrieve records from database wit tat userna

hello..
i got a ChangePassword.jsp which i retrieve the username from session using bean to display on e page..
<jsp:getProperty name="UsernamePassword" property = "username"/>
but in my servlet, i wan to retrieve records from database with tat username..
i tot of coding
String username = (String)request.getSession().getAttribute("UsernamePassword");
and then use tat username to retrieve records.. but is that e right way? The page did not display and i got a CastingException..
Please help.

If you are using the session inside a jsp, you can say "session" without having to declare it.String usernamePassword = (String) session.getAttribute("usernamePassword");However, right after you get this value, check if it is null:
if(usernamePassword==null)
// do sth like forward to error page
else
// continue processing
If it is null, then you are probably not setting it right in the first place. Make sure that in your servlet A you create a session, and before you return or forward to a jsp, that you actually set this value in the session like saying
session.setAttribute("usernamePassword", usernamePassword);
and it is case sensitive for the key.

select m.accid,m.title,d.dr,d.cr
from master m, detail d
where m.accid=d.accid (+)The outer join operator (+) will get you all the details from master and any details from the detail if they exist, but the master details will still be got even if there are not details.
Note: Oracle 10g now supports ANSI standard outer joins as in:
select m.accid,m.title,d.dr,d.cr
from master m LEFT OUTER JOIN detail d on m.accid=d.accid

Hi Joakins,
I think Lloyd has a point here in that all I see there which is really database related is a connection string.
Maybe your question is more general though and you're just asking how to work with a database as a general principle.
Personally, I like entity framework and would recommend that.
You can read a shed load of stuff about it.

How to save, update and retrieve data from two diffrent table

Hi,
I can save and retrieve data into an user defined SBO form from one database table only. How can I save retrieve and update records from two or more different tables in a single screen?
Regards,
Sudeshna.

Sudeshna,
Are these tables external to SAP Business One and do not have a Business Object? If there is a Business Object available such as if you were to enter an order, that order would use the Documents object which abstracts you, the programmer, from the underlying tables that need to be updated. If you are handling multiple business objects you would need to wrap the transaction with the StartTransaction - EndTransaction methods. This information is detailed in the SAP Business One SDK Help Center that comes with the SDK.
HTH,

How bapi different from session and call transaction?

how bapi different from session and call transaction?
thanks in advance.

For one, Batch Data Communication (BDC) is older. Business Application Programming Interface (BAPI) came later, about 10 years ago (you can see this already from the name, which contains marketese like "business" ).
More important though, they are different technologies. With BDC you build the "batch input transaction" yourself, with an ABAP program which creates the "batch input session" ("Batch-Input-Mappe" in german). You then take that session, like an object, and "run" it on a system (most of the time, this is done on a local system by the administrators, after it has been tested for correctness).
With BAPI, a system (local or remote) exposes its interface to you through some kind of Remote Function Call (RFC). Practically, it tells you: "What do you want to do? Insert that data into Materials Management? Here is the function and the the parameters you have to use for each record". You only work with the Interface - the exposed function. How this function works does not have to interest you. You don't have sessions to "run", you fire your function calls filled with data, one after another and you're done.
BAPI can be run remotely. With BDC, you probably have to call the administrators of the remote system and send them the session you created for them to run. With BDC you go through the whole transaction in one BDC session, with BAPI you may need more than one "BAPI calls" to do this.
With BAPI you don't fill obcure field names with values, you just fill the parameters. You can use a BAPI from inside your ABAP program to let a "business object" do some clearly defined work for you, then you can continue with your code doing other things. You don't do this with BDC. With BDC you write a dedicated program that creates the "session", which is then executed separately.
Batch Data Communication (BDC) is the oldest batch interfacing technique that SAP provided since the early versions of R/3. BDC is not a
typical integration tool, in the sense that, it can be only be used for uploading data into R/3 and so it is not bi-directional.
BDC works on the principle of simulating user input for transactional screen, via an ABAP program. Typically the input comes in the form of a flat file. The ABAP program reads this file and formats the input data screen by screen into an internal table (BDCDATA). The transaction is then started using this internal table as the input and executed in the background.
In Call Transaction, the transactions are triggered at the time of processing itself and so the ABAP program must do the error handling.
It can also be used for real-time interfaces and custom error handling & logging features. Whereas in Batch Input Sessions, the ABAP
program creates a session with all the transactional data, and this session can be viewed, scheduled and processed (using Transaction SM35) at a later time. The latter technique has a built-in error processing mechanism too.
Batch Input (BI) programs still use the classical BDC approach but doesnt require an ABAP program to be written to format the
BDCDATA. The user has to format the data using predefined structures and store it in a flat file. The BI program then reads this and
invokes the transaction mentioned in the header record of the file.
Direct Input (DI) programs work exactly similar to BI programs. But the only difference is, instead of processing screens they validate
fields and directly load the data into tables using standard function modules. For this reason, DI programs are much faster (RMDATIND - Material Master DI program works at least 5 times faster) than the BDC counterpart and so ideally suited for loading large volume data. DI programs are
not available for all application areas.
Business Add-In (BADI) are a new SAP enhancement technique based on ABAP Objects.
They can be inserted into the SAP System to accommodate user requirements too specific to be included in the standard delivery. Since specific industries often require special functions, SAP allows you to predefine these points in your software.
As with customer exits two different views are available:
In the definition view, an application programmer predefines exit points in a source that allow specific industry sectors, partners, and customers to attach additional software to standard SAP source code without having to modify the original object.
In the implementation view, the users of Business Add-Ins can customize the logic they need or use a standard logic if one is available.
In contrast to customer exits, Business Add-Ins no longer assume a two-level infrastructure (SAP and customer solutions), but instead allow for a multi-level system landscape (SAP, partner, and customer solutions, as well as country versions, industry solutions, and the like). Definitions and implementations of Business Add-Ins can be created at each level within such a system infrastructure.

Retrieving records from a Data Block same as retrieving records from cursor

Dear Gurus,
Is it possible to retrieve records from a datablock same as retrieving records from a cursor,
Eg:
I am having two data blocks in two different tabs, Say B1 in Tab1, B2 in Tab2
B1 is filled with two records, now when I switch to Tab2,
I want all records of B1 in B2, assuming that blocks are having the same structure.
The code I wish to write is,
Goto B1,
Take all the records like a cursor,
Goto B2,
loop
insert
end loop;
Is this possible???

I need to show it before saving,
I tried this and it is successful somehow, do not know about any further problems,
I took the record count of both blocks
if :B1.reccount <> :B2.reccount
               then
               go_block('B1');
               first_record;
               for i in 1..:B1.reccount
               loop
                    go_block('B1');
                    go_record(i);
          assign values from B1 to variables.
          go_block('B2');
          assign values from variables to B2
          next_record;
               end loop;
               clear_record;
          end if;
This is working, Now I just want to know, if my block is having numerous fields, say more than 100 (may not be a value for large databases)
how can I replace these variables here.
I mean is it possible to declare something like a cursor record type.
For eg : r1 cursor%rowtype

HT204291 Using Azul media player app on my ipad Apple tv will only display sound but not video from movies. Any ideas on a fix. I set mirroring to on but it still does not display video. It will display photos and video recorded from my iphone.

Using Azul media player app on my ipad Apple tv will only display sound but not video from movies. Any ideas on a fix. I set mirroring to on but it still does not display video. It will display photos and video recorded from my iphone.

Here are the steps for AirPlay:
Before starting Azul from your (running iOS 5.x/6.x) home screen where have have all your apps we need to turn on mirroring
On your iPhone 4S/5 or iPad 2 or 3, double-click the Home Button to view your recently-used apps.
Swipe all the way to the right to until you see the icon.
Note: If the icon does not appear, go to the "If AirPlay Mirroring is not visible or available on your mobile iOS device" section.
Tap the icon to see the list of available AirPlay devices.
Enable AirPlay Mirroring in this menu by tapping on an available Apple TV, then sliding the Mirroring slider to ON.
Now you should be seeing your iPad/iPhone on your TV.
Start up Azul now and using the settings icon on the top right corner go to the option that say "TV out" ON.
When you do that you will see an Orange screen
Now click "Done" and play the video you want to watch and it will AirPlay

Retrieving record from oracle DB very slow..pls help

Hi, i'm writing a VB code to retrieving records from Oracle DB Server version 8. I'm using VB Adodb to retrieve the records from various tables. Unfortunately one of the table are very slow to response, the table only contain around 204900 records. The SQL Statement to retrieve the records is a simple SQL Statement that contain WHERE clause only. Any issue that will make the retrieving time become slow? Is that a Indexing? Oracle Driver? Hardware Spec? Or any solution for me to improve the performance. Thanks!

Well, there are a few things to consider...
First, can you try executing your query via SQL*Plus? If there are database tuning problems, your query will be slow no matter where you run it.
Second, are you retrieving significantly more rows in this query than in your other queries? It can take a significant amount of time to retrieve records to the client, even if it's quick to select them.

Get the data from excel and insert into the database

I want to read the data from excel file, get the data from excel and insert into the database.

You can use the Apache POI HSSF API to read data from Excel files and you can use the Sun JDBC API to insert data in database.
This has nothing to do with JSP/JSTL.
