How can I use session in javabeans?

Thank you!

If your Javabean contains business logic, then you probably shouldn't be using an HTTP concept such as session. The JSP/servlet should extract whatever info is required and pass it to the bean.
If your bean is an HTTP/HTML helper and you need to reference session, then the only way is for the JSP/servlet to pass the session reference on a method call to the bean.

Hi,
Session Tracking is one of the most powerful features of Servlets and JSP. Basically, the servlet engine takes care of using Cookies in the right way to preserve state across successive requests by the same user. Your servlet just needs to call a single method (getSession) and it has access to a persistent hashtable of data that's unique to the current user.

How can i use session in this senario

Hi
i am using a jsp,in which i am collecting a string variable and using that variable in sql query to get one row displayed,(there are 2 pages one to pass some variable and another to collect it),now if i pass a variable again and query it to get the result ,though i am getting the result properly but it is overwriting the preveous row in my jsp ,what i want is for each session what ever variable i pass i want to print that many rows ,looking forward to your reply
thanx

1) Are you using Struts?
I suggest you to do so.. Its very simple and easy to maintain. I would do this in Struts, Make the bean in session scope. Have a list with getter and setter method and in the action class I would keep adding to the list. By doing this, I ensure better maintainability of the application.
2) If you are not using struts. Then keep a List in session. And keep adding to the list.

How can I use the same session for different components acroos application ?

I am trying to include the components(chat, filesharing, whitboard) in different parts of my application. User should be able to access any of the component. We would like to have a single "ConnectSessionContainer" so that we don't see same user creating a seperate session for each component.
Is there a better way of dealing with this other than declaring the "ConnectSessionContainer" in the main application ? Is there a way to check if we have a "ConnectSessionContainer" session already established ? Please help . Thanks.

Thanks for the response. Let me explain what I am trying to do..
I am trying to create components at different places(screens) of the flex application (not in the same .mxml file).
Each time I create a component, I am using a "AdobeHSAuthenticator" and "ConnectSessionContainer" which is resulting a new participant in the room.
For example
screen1.mxml -
<mx:Panel>
<rtc:AdobeHSAuthenticator id="auth" authenticationSuccess="onAuthSuccess(event);" authenticationFailure="onAuthFailure(event);" />
<rtc:ConnectSessionContainer id="mySession" >
        <rtc:Roster id="myRoster" width="100%" height="100%" />
        <rtc:Chat id="mychat" width="100%" height="100%" />
</rtc:ConnectSessionContainer>
</mx:Panel>
screen2.mxml (in the same application) -
<mx:Panel>
<rtc:AdobeHSAuthenticator id="auth" authenticationSuccess="onAuthSuccess(event);" authenticationFailure="onAuthFailure(event);" />
<rtc:ConnectSessionContainer id="mySession" >
        <rtc:SharedWhiteBoard id="wb" width="100%" height="100%" />
</rtc:ConnectSessionContainer>
</mx:Panel>
Here, I open a screen1 and authenticate as UserA and when I try to open screen2 flex is considering me as another user though I am in the same application.
1) How can I use different components which are in different flex files as a same User ?
2) Should I place my <rtc:AdobeHSAuthenticator> and <rtc:ConnectSessionContainer> in the main application which calls the screen.mxml?
3) What is the best way to do it ?
Thanks for your time !

How can we use TABLE CONTROL in BDC and WORK FLOW of ABAP.

how can we use TABLE CONTROL in BDC and WORK FLOW of ABAP.?
please explain the important questions.

How to deal with table control / step loop in BDC
Steploop and table contol is inevitable in certain transactions. When we run BDC for such transactions, we will face the situation: how many visible lines of steploop/tablecontrol are on the screen? Although we can always find certain method to deal with it, such as function code 'NP', 'POPO', considering some extreme situation: there is only one line visible one the screen, our BDC program should display an error message. (See transaction 'ME21', we you resize your screen to let only one row visible, you can not enter mutiple lines on this screen even you use 'NP')
Now with the help of Poonam on sapfans.com developement forum, I find a method with which we can determine the number of visible lines on Transaction Screen from our Calling BDC program. Maybe it is useless to you, but I think it will give your some idea.
Demo ABAP code has two purposes:
1. how to determine number of visible lines and how to calculte page number;
(the 'calpage' routine has been modify to meet general purpose usage)
2. using field symbol in BDC program, please pay special attention to the difference in Static ASSIGN and Dynamic ASSIGN.
Now I begin to describe the step to implement my method:
(I use transaction 'ME21', screen 121 for sample,
the method using is Call Transation Using..)
Step1: go to screen painter to display the screen 121, then we can count the fixed line on this screen, there is 7 lines above the steploop and 2 lines below the steploop, so there are total 9 fixed lines on this screen. This means except these 9 lines, all the other line is for step loop. Then have a look at steploop itselp, one entry of it will occupy two lines.
(Be careful, for table control, the head and the bottom scroll bar will possess another two fixed lines, and there is a maximum number for table line)
Now we have : FixedLine = 9
              LoopLine = 2(for table control, LoopLine is always equal to 1)
Step2: go to transaction itself(ME21) to see how it roll page, in ME21, the first line of new page is always occupied by the last line of last page, so it begin with index '02', but in some other case, fisrt line is empty and ready for input.
Now we have: FirstLine = 0
          or FirstLine = 1 ( in our case, FirstLine is 1 because the first line of new page is fulfilled)
Step3: write a subroutine calcalculating number of pages
(here, the name of actual parameter is the same as formal parameter)
global data:    FixedLine type i, " number of fixed line on a certain screen
                LoopLine type i, " the number of lines occupied by one steploop item
                FirstLine type i, " possbile value 0 or 1, 0 stand for the first line of new                                                               " scrolling screen is empty, otherwise is 1
                Dataline type i, " number of items you will use in BDC, using DESCRIBE to get
                pageno    type i, " you need to scroll screen how many times.
                line      type i, " number of lines appears on the screen.
                index(2) type N, " the screen index for certain item
                begin     type i, " from parameter of loop
                end       type i. " to parameter of loop
*in code sample, the DataTable-linindex stands for the table index number of this line
form calpage using FixedLine type i (see step 1)
                   LoopLine type i (see step 1)
                   FirstLine type i (see step 2)
                   DataLine type i ( this is the item number you will enter in transaction)
          changing pageno    type i (return the number of page, depends on run-time visible                                                                             line in table control/ Step Loop)
          changing line      type i.(visible lines one the screen)
data: midd type i,
      vline type i, "visible lines
if DataLine eq 0.
   Message eXXX.
endif.
vline = ( sy-srows - FixedLine ) div LoopLine.
*for table control, you should compare vline with maximum line of
*table control, then take the small one that is min(vline, maximum)
*here only illustrate step loop
if FirstLine eq 0.
        pageno = DataLine div vline.
        if pageno eq 0.
           pageno = pageno + 1.
        endif.
elseif FirstLine eq 1.
        pageno = ( DataLine - 1 ) div ( vline - 1 ) + 1.
        midd = ( DataLine - 1 ) mod ( vline - 1).
        if midd = 0 and DataLine gt 1.
                pageno = pageno - 1.
        endif.
endif.
line = vline.
endform.
Step4 write a subroutine to calculate the line index for each item.
form calindex using Line type i (visible lines on the screen)
                    FirstLine type i(see step 2)
                    LineIndex type i(item index)
          changing Index type n.    (index on the screen)
if FirstLine = 0.
        index = LineIndex mod Line.
        if index = '00'.
                index = Line.
        endif.
elseif FirstLine = 1.
        index = LineIndex mod ( Line - 1 ).
        if ( index between 1 and 0 ) and LineIndex gt 1.
                index = index + Line - 1.
        endif.
        if Line = 2.
                index = index + Line - 1.
        endif.
endif.
endform.
Step5 write a subroutine to calculate the loop range.
form calrange using Line type i ( visible lines on the screen)
                    DataLine type i
                    FirstLine type i
                    loopindex like sy-index
        changing    begin type i
                    end type i.
If FirstLine = 0.
   if loopindex = 1.
        begin = 1.
        if DataLine <= Line.
                end = DataLine.
        else.
                end = Line.
        endif.
   elseif loopindex gt 1.
        begin = Line * ( loopindex - 1 ) + 1.
        end   = Line * loopindex.
        if end gt DataLine.
           end = DataLine.
        endif.
   endif.
elseif FirstLine = 1.
if loopindex = 1.
        begin = 1.
        if DataLine <= Line.
                end = DataLine.
        else.
                end = Line.
        endif.
elseif loop index gt 1.
        begin = ( Line - 1 ) * ( loopindex - 1 ) + 2.
        end =   ( Line - 1 ) * ( loopindex - 1 ) + Line.
        if end gt DataLine.
                end = DataLine.
        endif.
endif.
endif.
endform.
Step6 using field sysbol in your BDC, for example: in ME21, but you should calculate each item will correponding to which index in steploop/Table Control

      name2(14) value 'EKPO-MENGE(XX)',

assign:         name1 to <material>,
                name2 to <quan>,
                name3 to <indicator>.
do pageno times.
if sy-index gt 1
*insert scroll page ok_code"
endif.
        perform calrange using Line DataLine FirstLine sy-index
                         changing begin end.
loop at DataTable from begin to end.
        perform calindex using Line FirstLine DataTable-LineIndex changing Index.
        name1+11(2) = Index.
        name2+11(2) = Index.
        name3+12(2) = Index.
        perform bdcfield using <material> DataTable-matnr.
        perform bdcfield using <quan>     DataTable-menge.

How can i use the project code instead of project xml?

hello
i use the sessionbean+toplink structure,after i finish the o-r mapping by using the mapping work bench,i generate the project xml file,then in the "session.xml" file,i refer to the project xml,then i can use it from sessionbean.
i hear that if i use the project code instead of project xml file,it will be more performant,is that true?
otherwise,how can i use the project code instead of project xml file?i mean, in "session.xml", i can use the "<project-xml>" tag to refer to the project xml file,then in my session bean,i get the server session by read the "session.xml" file.but if i use the project code,how can i refer it from the "session.xml"?the examples that come with the toplink installation only tell me how can i use the project xml file within the session bean,it don't give me any clue about using the project code in the sesion bean,who can give me a step-by-step instruction and code snippet?
thank you very much?

There is a slight performance gain during session load at startup but there is no difference at runtime. The choice of which to use is dependent upon you build process. Whether it is easier to submit a new version of the class into the comile build process vs an XML file. In most cases it is just a preference of the development team.
When you use the project-class you'll need to generate the source code and compile it into your system. Typically it is packaged with the persistent classes. You may need to configure your environment so that the class-loaders have access to these classes (same for the XML case).
When using the project-class you simply replace the project-xml entry like this:
<project-class>oracle.toplink.demos.employee.relational.EmployeeProject</project-class>
The DTD for the session.xml file is found at <TOPLINK_HOME>\core\sessions_4_5.dtd. It is also in the documentation at:
http://otn.oracle.com/docs/products/ias/doc_library/90200doc_otn/toplink.903/b10064/a-sessio.htm#634246

How can I use TrueSequenceFactory with multiple sequences

In the post "How to use existing Oracle sequences using KODO" answered
by Marc Prud'hommeaux a "sample code" was given. But seems to me that
example will only work with a single Oracle sequence for the entire
system. Is this right?
How can I use TrueSequenceFactory with primary-keys and their
respective existing sequences? Can you (SolarMetric guys) provide me a
sample code?

The problem is that you are using application-identity. When you
specify an objectid-class, we treat is automatically as application
identity. To resolve this, I would recommend removing both the
objectid-class and identity-type atributes from your class. With
"objectid-class" in place, we asssume that you wil take care of identity.
Eduardo Bobsin Machado wrote:
I'm using Kodo 2.4.0, Oracle 9i, JBoss 3.0.4, the Kodo jars are in the
JBoss' lib/ext.
Well, I'll show what I have...
This is the script of my table:
CREATE TABLE LINEUP_VOYAGE (
VOYAGEID NUMBER (10) NOT NULL,
VESSEL_NAME VARCHAR2 (1000) NOT NULL,
CONSTRAINT PK_LINEUP_VOYAGE
PRIMARY KEY ( VOYAGEID ) ) ;
This is an excerpt of my .jdo file:
<class name="LineupVoyage" objectid-class="LineupVoyageId"
identity-type="datastore">
<extension vendor-name="kodo" key="table" value="LINEUP_VOYAGE"/>
<extension vendor-name="kodo" key="sequence"
value="LINEUP_VOYAGEID_SEQ"/>
<extension vendor-name="kodo" key="pk-column" value="VOYAGEID"/>
<extension vendor-name="kodo" key="lock-column" value="none"/>
<extension vendor-name="kodo" key="class-column" value="none"/>
<field name="vesselName">
<extension vendor-name="kodo" key="data-column"
value="VESSEL_NAME"/>
</field>

</class>
As you can see, the "id" field is commented.
And this is my class:
package br.com.fertimport.entity;
import java.util.*;
public class LineupVoyage {
     private String vesselName;
//     private long id;
//     public LineupVoyage(long id) { this.id = id; }
//     public long getId() { return id; }
//     public void setId(long id) { this.id = id; }
     public String getVesselName() { return vesselName; }
     public void setVesselName (String vesselName) { this.vesselName =
vesselName; }
The "id" attribute is commented.
Now the questions...
To use ClassSequenceFactory must the identity-type of my entities be
application or datastore?
Is the "objectid-class" parameter required in this case?
As you see, all references to the "id" property are commented. Can I
use this property to represent my object id?
If not, how can I identify my object with something like a long?
The last question is related to my architecture: one VM with the EJBs
(entity and session) and another VM with the web classes and JSPs,
connected by a session facade. I don't want to use any Kodo or JDO stuff
in the web tier. Is this possible?

How can I use Local SPAN with RSPAN ??

How can I use Local SPAN with RSPAN ??
I want to mirror traffics from ISP-A and ISP-B to Anomaly-detector module.
so I had configured like this...
C6500-A
vlan 1000
name RSPAN
remote-span
monitor session 10 source interface Gi5/1 - 2 rx
monitor session 10 destination remote vlan 1000
monitor session 20 destination anomaly-detector-module 3 data-port 1
monitor session 20 source remote vlan 1000
interface GigabitEthernet1/13
switchport
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1000
switchport mode trunk
no ip address
C6500-B
vlan 1000
name RSPAN
remote-span
monitor session 10 source interface Gi5/1 - 2 rx
monitor session 10 destination remote vlan 1000
interface GigabitEthernet1/13
switchport
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1000
switchport mode trunk
no ip address
end
but it was not working..
it wasn't any change of input packet hit count when
I'd enter a command 'show anomaly-detector module 3 data-port 1 traffic'
was upper configuration wrong..?
Can I use VACL configuration ?

try to change "monitor session 10 destination remote vlan 1000 " to "monitor session 10 destination anomaly-detector-module 3 data-port 1 " on C6500-A

How can i use PCIe 1433 and basler line camera to construct image and pocess it?

hello! every one ,I am new to machine vision.i have two problems to ask.First,how can i use line camera and 1433 to acquire 2-D image?second,if i want to pocess the 1-D signal ,how can i do it ?i expect for your answer ,thank you!

What you are trying to do is not something you can easily do in a forum, but I can give you the basics.
You have a CameraLink frame Grabber (PCIe 1433) and a LineScan Camera
The framegrabber needs to be configured to understand how to communicate with the camera. You need a file from the camera vendor. This file might already be installed. You can use MAX to check if it is, under Devices/IMAQ.
Assuming you can get to the point where you can communicate with the camera, you need to configure your acquisition.
Since the camera is a line scan camera, it captures image data one pixel ine at a time. You will need to configure the frame grabber to determine how many lines per image you want. The low limit is usually 1, and the high limit is either based on the framegrabber's internal memory, or that of the computer.
If you are using labview, you will need to open a sessing to the camera, acquire the image(s), and then close the session when you are done.
Once the image(s) are captured, you can performa analysis using the NI Vision Toolkit.
Sorry, but there is no way to condense years into one post.

How can i invalidate Session when a browser crashes?

Hi
How can i invalidate session when a browser window closed or crashed unexpectedly.
If user closed the browser window using File->Close, then i'm calling javascript function .... and it is working fine. But when browser window is hanged and closed using ENDTASK, how can i kill that session.
Please help
Thanks
-Vidyadhar

Well you can't. Execution halts, so anything you would want to do is made impossible: that's why crashes are the #1 enemy of any software developer (that and impossible deadlines). The webserver will remove the session manually when it times out though.

please expert help me . thanksyou can only create subfolders in a imap mail server ,and you can use folder class included in javamail api to access,create,modify and delete subfolders.You also can create subfolders under a subfolder as you want.
the simple example is:
//first create mail session
mailSession=...
// second create mail store
mailStore=...
//third get root folder
IMAPFolder rootFolder = (IMAPFolder)mailStore.getFolder("INBOX");
if ((rootFolder==null)||(!rootFolder.exists())) return false;
//finally create a subfolder "outbox" under root folder "inbox"
IMAPFolder tmpOutFolder = (IMAPFolder)rootFolder.getFolder("OUTBOX");
if (tmpOutFolder==null) return false;
//if the target folder not exist just create it
//note:when you create a subfolder you can assign its attribute.Details,please read the javamail document.
