How to check whether a user session is null or not

Hi
I am using Jdeveloper 11.1.2.2
I have a use case of running some Junit test case, this is the problem I have :
There are some Junit tests which are written for some VO's. While testing insert and update operation in Junit there is two mandatory columns Created by and Updated by to be entered for committing into the database.
These values are taken from the UserName of the current UserSession .
So for getting the these values for each user I thought of displaying a JPanel before the test is run, where the user enters the Username and password which is validated and the user is verified.
First, I need to check whether there is a session present or not. For checking this, I wrote a createUserSession() and did like this inside it :
if(fixture.getApplicationModule().getSession().getUserData().isEmpty())If so to show the Jpanel and get the user details and verify the user.
But while running the test itself I found that the session is already present, now I just have to input the values based on who is the user.
But Junit doesn't run the tests in the order in which the test are written. So I have to call this in all the test cases.
The Question is :
How can I check whether the session is already present or not, so that I don't have to ask the user every time while every test is running to enter the Username and Password ?
Thanks,
Nigel.

Hi,
wondering why don't you create test users and then automatically log them in as Jan Vervecken did on the threads I pointed you to. This way your test cases run without user interaction. To test if a session exists for a user, I would put a custom property into user data. If this property exists, the user session is an existing one. However, make sure the information you save into the user data survives passivation as otherwise the information you get out of this is not accurate.

How to check whether the user has a certificate or not?

Hi everyone.
We're currently finishing a web project and the last step is to check whether users accessing the application have a valid certificate or not.
Users with a valid certificate can access all the data. Users without any certificate installed on their browsers may still proceed, but they won't be able to see all data. Please note that the lack of a certificate doesn't mean an error - it's just another use case.
Is there any way to check whether users have a certificate installed on their browsers?
Thanks in advance.
Edit: sorry, I forgot to post some tech details. We're using Struts 1.2 on a Tomcat 5 app server.

I am not sure how Tomcat handles this, but you need to use two-way (mutual authentication) request but not enforce SSL between Tomcat and the client browser. This will make the browser prompt the user for the cert they want to send. Then you'll need to tackle the other part of your problem, getting the correct content displayed depending on whether the user sent a cert or not. I'm even less help there than I was on the first part of your question.
So, yeah - good luck with that

What's the best way to check whether a user is logged in or not?

I have a question about basic session handling.
I'm running Tomcat 5.0.30 and have a web application where users can register with a username and password, and then log into a "member site".
What is the best way of making sure that a user actually has logged in or not?
What I've done in previous applications I've made is that I've just put a simple variable into the users session after he has successfully entered his password (i.e. Boolean loggedIn=true). Then I just test if this flag is true to grant him access to the member site. Is that a smart way of doing it?
Are there any libraries I can use which handles sessions for me in a secure way?
All comments and suggestions are appreciated!

Maintain a flag using session attributes it to one when the user is logs in set it to value.... and change set it zero or invalidate that session... when the user is logged out...
use something like this while user had logged in
session.setAttribute("flag",<unique_number>);
for checking whether the user had logged in or not...
if(Integer.parseInt(session.getAttribute("flag").toString())=!<unique_number>){
out.println("The session had expired");
out.close();
}

How to check if a user session is active in Java application server

Hi Experts,
We have a online scenario with a third party system by which a portal user will launch the third party application in a new window from portal. The SSO will work at the third party web application with the dynamic key that is generated by calling a webservice for that user. Now, as the user works on the launched screen, they will have to check whether the user (logged in portal) session is still active. ie., they will be periodically calling a service hosted by SAP java application server to find out whether the corresponding user who launched the session is still logged in or logged out.
So, my question is, how can i find out programatically whether a user/user's session is still logged in/active in SAP Netweaver Java AS? We are in version 7.3.
Kindly help me in this regard.

Vijay.K

Hi Vijay,
Could you check below links

Hope this helps.

How to check whether the Application Server directory exits or not

Hi,
I have a selection screen in which I give the Application server file name(UNIX file) as input. Here, I would like to check whether the Server directory exists or not.
Let us say, the path I gave in the selection screen is /usr/sap/tmp/testfile.txt . Here, the file name is testfile.txt and the server directory is /usr/sap/tmp . I would like to check whether this directory /usr/sap/tmp exists in the server or not. I am not bothered about the file name as I am going to write data into the file. I am mainly concerned about whether the directory exists in the server or not. and one more thing... this is the Application Server path not the Local path.
Can anyone help me on the same how to check whether the server directory exists or not.
Thanks in advance.
Best Regards,
Pradeep.

Also you can use the FM EPS_GET_DIRECTORY_LISTING for this purpose.
Store the directory name
 l_dpath = p_file+0(l_no).
Validate the directory of the application server
 CALL FUNCTION 'EPS_GET_DIRECTORY_LISTING'
 EXPORTING
 dir_name = l_dpath
 TABLES
 dir_list = l_i_dlist
 EXCEPTIONS
 invalid_eps_subdir = 1
 sapgparam_failed = 2
 build_directory_failed = 3
 no_authorization = 4
 read_directory_failed = 5
 too_many_read_errors = 6
 empty_directory_list = 7
 OTHERS = 8.
If any problem occurs with the directory then display proper
error message
 IF sy-subrc <> 0.
 Display error message
 MESSAGE e018 WITH 'Problem with directory entered'(008).
 ENDIF. " sy-subrc <> 0

How to check whether set up tables are filled or not

Hi Gurus,
How to check whehter set up tables are filled or not?
Cheers,
Reddy.

Hi Reddy.......
And another point I want to make u clear............LBWQ is not the Delta Queue.............Delta queue is RSA7...............it comes into play in delta loading.......LBWQ is Extraction Queue.........While delta loading....if we use the Update mode Queued Delta........then any Changes will not directly get updated in the Delta queue.....For the Delta set up.........
1) First u hav to run init with data transfer(After filling the set up table)
2) After that any Changed ........will be recorded in the Extraction Queue(LBWQ)........
3) After a certain number of records get accumulated in LBWQ........We hav to run V3 jobs to bring the data in the Delta queue(RSA7)...
Check this.....

How to check whether an invoice has been paid or not?

Hi,
In FI, how should I check whether an invoice is paid fully and also whether it has any residual item?
And how should I pay an invoice with some residue? Which transaction I should use and what are the steps to do that?
Since I'm new to FI, any guidance will help me a lot...
Thanks,
Priya.

Hi Priya,
you create a posting with residual items as follows:
Incoming payment
1. Start transaction F-28
2. Enter all required information and click on Process open items
3. On the next screen click on the tab Res. items
4. Make sure that only the items that you want to pay are highlighted ((Net amount appears in blue)
5. For each line item enter the residual amount that is still to be paid (Example: you have one invoice over 100 USD and 80 USD are paid, you enter 20 USD, since this is your residual that still needs to be paid)
6. Save
Outgoing payment
1. Start transaction F-53
2-6. is identical to incoming payment

How to check whether INSO Filer is being used or not?

Hi,
We have created full text search indexes using the default syntax -
CREATE INDEX FTI ON DOCUMENTS(DOC_FILE) INDEXTYPE IS CTXSYS.CONTEXT;
How can I find out whether the INSO filter is used or not. Also a basic question, INSO filter helps in reading and "crawling" some 100+ document formats and creating an index against which search could be executed.... right?
Please do let me know.
Thanks & Regards,
Dhwanil

you can specify the inso filter in index code creation.
create index TEST_IDX
on TEST_TABLE (TEXT)
indextype is ctxsys.context
parameters('filter ctxsys.inso_filter');

How to check whether a list item is highlighted or not

I have delete button.Have to alert the user if user does not select any itemin list
Below is the code I have written in When Button Pressed Trigger:
Begin
v_currValue := NULL;
v_currValue := Name_In('CONTROL.ENTITY_LIST');
If (v_currValue is null) then
     v_alert_button := MSGBOX ('Select the entity type to be deleted.', 'STOP', 'Delete');
               if v_alert_button = alert_button1 then
                    raise      v_exception ;
                         go_item('CONTROL.ENTITY_TYPE');
               end if;
          End if;
v_curlist_index     := Get_List_Index ('CONTROL.ENTITY_LIST');
Delete_List_Element('CONTROL.ENTITY_LIST',v_curlist_index);
End
Above code works fine means alerts the user when there are no elements in the list.
And if there are 4 elemnts
emp
dept
sal
loc
when clicks delete button it alerts the user to select the item
now v_currvalue = emp;
after deleting list contains 3 values
but v_currvalue still remains 'emp'
even i keep vcurrvalue = null or ''
it is still emp.
Is there any way to solve this or there is any bug inmy code.
Could anyone helpme in this?
Thanks,

b]/** First approach which didnt worked **/
Begin
v_currValue := to_char(' ');
v_currValue := Name_In('CONTROL.ENTITY_LIST');

End if;
v_curlist_index := Get_List_Index ('CONTROL.ENTITY_LIST');
