Passing data to a separate jpf

What is the best practice for passing data from one jpf to another? I have a collection of jpf's generated from rowset controls. And, I would like some of them to restrict their query only to the parent row as selected in a previous screen. What is the bestway to minimize maintenance and rework to store this key, and use it in the receiving jpf rowset control? Should I simply save it in global, and modify the sql in the receiving jpf's associated rowset control?

Thanks. Unfortunately when I try to follow the url you provided it dumps me in the help files:
http://e-docs.bea.com/workshop/docs81/doc/en/core/index.html
And, when I try to enter the url explicitly, I get an error saying I do not have sufficient authority to access it. I get this at the samplesrc directory.

PASSING DATA FROM FORM TO REPORT (how to on the same page?)

Hello everybody
yes, i know it is built in a two pages design where the first holds the form and the second the report, but I want it both on the same page so that one can see what he has on the report while adds his own row to the table. Well I could do creating a form and then editing the page and then add another region. Alright. But then i dont know how to relate them together so that the data pass from the form to the report.
Besides, the Form for filling the data needs to pass them to two separate tables, because one table contains the particulars of the location and the other the comments about each store. Easy to do that on PHP and mysql but here I am lost.
Second thing that is driving me nuts is that I created a table named location so as to street postcode for a store, and another one for evaluation so that customers or workers add a a row evaluating services etc.
Well, I am trying to create that form i first talked about that would hold all the fields and I am doing it out of a SQL query that picks the definitions from both tables. My XE is completely empty from any leftovers of other applications etc. I make the equijoin alright
select l.loc_id, l.company, l.postcode, l.street,l.town, e.eval_id, e.loc_id, e.locum_reg, e.date_booked, e.items, e.addicts, e.number_staff, e.attitude_staff, e.organisation, e.stock_filing, e.agency
from location l, evaluation e
where l.loc_id = e.loc_id
and i get this annoying error all the time
ORA-20001: Unable to create form on equijoin. ORA-20001: Error page=2 item="P2_LOC_ID" id="1324114494879878" ORA-20001: Error page=2 item="P2_LOC_ID" id="1324114494879878" has same name as existing application-level item. ORA-0000: normal, successful completion
well, if that form is made up of both tables, it will definitively have to have something in common with them! how is the item name suppose to have another name? it is made with the wizzard so supposedly the wizzard should know it but I have tried for two days 14 hours each day.
any indication as to how solve this would be priceless for me
thank you

I'm just guessing, but it appears since you are selecting loc_id twice (once from each table) there are two items generated called P2_LOC_ID, and that's simply not possible (well - how would the application know which one you mean if there could be two with the same name?).
Maybe it's worth trying the following:
select l.loc_id as "L_LOC_ID", l.company, l.postcode, l.street,l.town, e.eval_id, e.loc_id as "E_LOC_ID", e.locum_reg, e.date_booked, e.items, e.addicts, e.number_staff, e.attitude_staff, e.organisation, e.stock_filing, e.agency
from location l, evaluation e
where l.loc_id = e.loc_id
Another option is creating a view on the two tables (of course you must use 2 different column aliases for the two loc_id columns in the view too, otherwise you will receive an ORA-00957: duplicate column name) and use the view for creating reports and forms - however, automatic row processing works just on one table, so you would have to create your own processes to perform the DML...
Edit: I just saw you already got this answered in the APEX forum.

Passing data to multiple screens through SAP webgui;

Hello, I'm working on building an application that requires me to pass data to multiple screens of a SAP transaction (IW31) through SAP webgui. The requirement is to enter the required information in the initial screen, "Header data" screen and in the "Object Data" screen. I'm using the below URL to launch the webgui:
http://myserver:8001/sap/bc/gui/sap/its/webgui/!?sap-client=800&sap-user=xxx&sap-password=yyy&sap-language=EN&transaction=iw31%20CAUFVD-EQUNR=20006001&AUFPAR-PM_AUFART=PM01&CAUFVD-GSBER=0001&OKCODE=/00&CAUFVD-ILART=103&~OKCODE==IOLU
This is failing with the following error message:
*Flow control: Entry SAPLCOIH, IOLU, A0, * , * , * is missing in T185*
I also noticed that if I stop at the point where I enter information in the initial screen and enter into the header data page using the below URL, it is working fine. The URL used is
http://myserver:8001/sap/bc/gui/sap/its/webgui/!?sap-client=800&sap-user=xxx&sap-password=yyy&sap-language=EN&transaction=iw31%20CAUFVD-EQUNR=20006001&AUFPAR-PM_AUFART=PM01&CAUFVD-GSBER=0001&OKCODE=/00
Can anyone please explain what is incorrect in the URL I'm passing?
Thanks in advance

Hi Vijay,
Thank you for your prompt response but I do not understand your answer or perhaps I am not makig myself clear.
Let me explain the current process:
1) Z program collects data and exports to Memory ID 'TEST01'.
2) Z program calls SAP program
3) SAP program calls User Exit '001' and data is read from Memory ID 'TEST01'.
4) SAP program collects some of the data and then executes SAP FM to continue processing.
5) SAP FM Executes User Exit for FM and data is read from Memory ID 'TEST01'.
6) SAP FM returns completed data back to SAP main program.
7) Z Program collects results from SAP program.
New process:
1) Z program collects data and exports to Memory ID 'TEST01'. Data now includes filter for CC.
2) Z program calls SAP program
3) SAP program calls User Exit '001' and data is read from Memory ID 'TEST01'.
4) SAP program collects some of the data and then executes SAP FM IN PARALLEL PROCESSING to continue processing.
5) SAP FM Executes User Exit for FM and an attempt to read data is read from Memory ID 'TEST01' fails.
6) SAP FM returns completed data back to SAP main program.
7) Z Program collects results from SAP program.
The dilemma is how to capture the proper CC filter in the FM exit when SAP is unable to read the data from memory ID 'TEST01'. I guess I can understand this since the tasks are executed in separate sessions and servers from the one that started the program since we are using a server group.
Perhaps I am missing something with respect to exporting to memory IDs?
Thanks.

Sharing data between two separate user sessions

Hi all!
I have been trawling my brain for a solution to this - any help will be appreciated!
I would like to create a single instance of a class but share that instance over more than one user session (two separate users but both running concurrently).
Just as you can pass data between sessions using ABAP memory - I would like to pass data (specifically an object reference) between two separate users that could even be logged in to two separate application servers...
Even a mini Client/server solution would suffice but I cannot figure one out!
Is this possible?
Many thanks for your thoughts in advance...
N

Hello N K,
sorry thats not possible. Sharing a data item / object instance requires at least a common physical memory. As this is not guaranteed between different app. server this is technical not possible.
With release 640 ABAP offers the new feature Shared Objects. These mechanism allows access by different users and some propagation to differnt servers.There is an interesting article on the ABAP SDN homepage
https://www.sdn.sap.com/sdn/developerareas/abap.sdn
For relases below more or less the database is the only chance to store data accross application servers (known to me). One exception might be the ENQUEUES which might (mis)used to store some Flags.
Kind Regards
Klaus

This should be so:
A person goes to work to place A
At the end of the day, he or she goes into the web fills the form and clicks the botton. Then, he or she has added a row to the form. As simple as that. But bear in mind that that form is comprised of data about the address and the comments, which are completely different entities, and not all elements of each entity is to appear in the report. That is why they have to go to two tables on the background and then the report pick from each table what it wants to show publiclly.
What I am actually trying to do is passing the values from the form into the two separate tables Location and Evaluation. Then I have already placed a select query under the report and I have seen that it updates itself as I manually filled the two tables so this process works fine. What I need is, instead of filling the tables manually as I am doing, fill them through the completion of the textfields of the form. This is so because not all the fields have to be shown on the report, for example, the person reporting will remain anonimous and that is something I am able to do by simply not including him in the select query of the report.
I am like exploring now the edit page possibilities and indeed I have discovered that the button of the Form that says create is associated with a Insert request on the database. Also i have seen that the way this works is by something like this P3_POSTCODE, &P3_POSTCODE where P3 is the item and &P3 is the value that is in the textfield associated with that item name.

Best way to pass data sets to another program

Hey
I want to connect another (maths) program with my java application. Therefore I need to paste data (some kind of tab separated table) to this program.
I try now to save these data in a separate newly generated file and to pass a command with Java's Runtime.exec() method to this program to read these data. Is this a good idea or might there be better ways?
If I do so, is there a way in Java to generate some kind of a "temporary" file which will be deleted automatically after usage or is this nothing else than to save it in a common file and delete it afterwards. What's the best way to pass data generally?

Well, the connection will not be over a network, so I'd rather think it's not a Socket or RMI problem (unless someone convinces me).
Yes it's very external, it's a C or C++ written program, I don't have any source codes. So far I generated a file for Input command and data, I passed that on to the maths program and returned the output into another file.
Now I would like to separate the output and like to obtain some tables and graphical things like charts at the output. Do I have to generate three different types of outputfiles? How to store some graphics e.g. some distributions. I thought even of generating a database. I never thought about XML, I don't know if this works for that kind of problem?!

Passing data to and from Comm Sub Vi with 2 loops

Im sure this is simple, and I think Im stuck in vacation mode and cant wait the 4 more hours till I leave, but this is really bothering me. I have a pretty large Queued State Machine and within that machine I have some states which must communicate via the TCP/IP port. My servers are complete and made into Executables and work fine, however I want to leave my clients as sub vi's so that I can easily pass in and retreive data from them. They are designed with 2 while loops, one for sending the data and one for reading the data back. At the very least the read loop needs to remain in a loop to pick up unsolicited messages from my CAN server. However when I place these into my master QSM they hold up the process because of the loops executing. Now I have made a separate loop in my QSM for all my communication clients so the rest of the QSM runs but I cant pass data into these clients because they are stuck executing the loops internally and dont stop to pull in data.
I should note that if I run my QSM to spawn the servers, then run my client as a separate VI rather than a sub and type my commands there then they execute perfectly.
So if you can follow my crazy description what would be the best/cleanest way to circumvent this so I can get moving ahead. Thanks, Dave

Dave,
Would it work to use a queue to pass data from your main QSM loop to your communication loop? You could write the commands to the queue from your main QSM loop, and pick them up in the communication loop. They would then still run in parallel. Let me know if this works, or if you are looking for something else.

Passing data into event

Simple Question: I have text controls that I wish to take values from when a button is pressed. Using Events, how do I get values and store them...

Are the values needed in any other portion of the program other than when the button is pressed? If not, you could place the controls within the event structure so that their values are only read when the button controlling the event structure is read. Note, though, that if the values are passed from the event structure to other portions of the program you need to determine the best approach for passing data when the button is not pressed (perhaps passing through a value from the last event).
In the event that the controls are needed in other parts of the program separate from the event structure you can use local variables to read the current value of the controls.
I hope this helps.

TCP Communication Problem - not passing data???

Hello.
I am working on TCP communication. I need to pass data from one PC to another and vise versa. I started with the shipped example TCP Communicator Active and Passive VI. Using the shipped example only with the Wireless Unit connected to both PC i am able to communicate and pass data between each PC.
Now, placing the shipped example VI to my Main VI (separate while loop), I am NOT able to make it run properly. What happens is even if i move the control data on one PC it does not update to the other PC.
I am attaching the example VI and I would appreciate for any advise.
Thank you very much.
regards,
jtc

Hi jtc,
"if you need to share data aquiired rapidly, a work-around is to accumulate the acquired data and send larger "bundles" less frequently" - do you have a simple example VI for this?
No! - though we could develop something - but a solution for the current example, might not be helpful to your final program. For instance, we would capture & accumulate a "batch" of data "produced" by individual user actions, then send the "batch" of data to the other machine and what? Perform all the updates to the GUI in rapid succession (what's the point?.) Show the last user action/setting?
It might be a good time to develop the architecture for the Master and Slave applications.
This sounds like an interesting application! Do you mind sharing some detail? For instance, are the slaves generating data? Are there a fixed number of slaves? Is it necessary to mirror the Master's data on all the connected slaves?
Like Johnny-5 said: "Input, I need Input!"
Cheers!

Can not pass data after while loop

Hello.
I have created a VI for my experiment and am having problem passing data outside a while loop to save on an excel file. The VI needs to first move a probe radially, take data at 1mm increment, then move axially, take data radially at 1mm increment, then move to the next axial position and repeat. It would then export these data to an excel file. The VI is a little complicated but it's the only way I know how to make it for our experiment. I have tested it and all the motion works correctly, however I can not get it to pass the data after the last while loop on the far right of the VI where I have put the arrows (Please see the attached VI ). Is it because I'm using too many sequence, case, and while loops? If so, what other ways can I use to make it export data to the excel file?
Any help would be appreciated.
Thank you,
Max

Ummmm .... gee, I'm not even sure where to begin with this one. Your VI is well .... ummmm... You have straight wires! That's always nice to see. As for everything else. Well... Your fundamental problem is lack of understanding of dataflow programming. What you've created is a text program. It would look fantastic in C. In LabVIEW it makes my heart break. For a direct answer to your question: Data will not show up outside a while loop until the while loop has completed. This means your most likely problem is that the conditions to stop that specific loop are not being met. As for what the problem is, I don't even want to start debugging this code. Of course, one way to pass data outside of loops is with local variables, and hey, you seem to be having so much fun with those, what's one more?
This may sound harsh, and perhaps be somewhat insulting, but the brutal truth is that what I would personally do is to throw it out and to start using a good architecture like a state machine. This kind of framework is easy to code, easy to modify, and easy to debug. All qualities that your code seems to lack.

How to pass date parameter from one page to other in BSP application

Hello gurus,
In my BSP application i have taken an input field and made its type "date" and its value also of type date and have set showhelp .
Now once a particular date is given as an input i want to pass its value to next page. And in next page i have to fire a query based on the date entered in previous page...
Now my prb is that my date value is not getting passed to the next page.
I have used
navigation->set_parameter( name = 'BEGDA' value = BEGDA ).
to pass date parameter.....still parameter is not getting passed.
plz help me with this.....
thankx.....

Hi Eddy,
By truncation i mean the entire date becomes 10 char including the ' . ' eg(06.12.2006).
so with begda being 8chars it takes my date as 06.12.200
as a result my query is not getting executed.
now i have tried to use a FM 'CONVERT_DATE_TO_INTERN_FORMAT'.
in my 1st page but still in 2nd page its giving me following error.
<b>The data that was read could not be written to the specified target field during a SELECT access. Either the conversion is not supported for the type of the target field, or the target field is too short to accept the value, or the data is not in the appropriateformat for the target field.

Passing date parameter from prompt

Hi experts
I am getting some problem while passing date from a dashboard prompt.
In RPD i have changed the date column properties as DATE only so that i will get the DATE part of the data not the time stamp.
Now in the dashboard prompt i added a prompt for the date column.
I initialized the date prompt with a server variable of sysdate
when i am running the dashboard i am getting default value in the prompt(04/15/2011)
when i am changing the date it is selected as(04/15/2011)
but when i am clicking the 'Go' button the date is converting to 2011-04-15 00:00:00 due to which my report is not running and i am getting error as
View Display Error
A date value was expected (received "2011-04-15 00:00:00").
Error Details
Error Codes: QABPH2PO
can anyone help me to pass only date part
thanks in advance

Gourisankar

Hi J / Srikanth
Sorry to restart the thread again.
As we discussed i have downloaded the patch and applied to my windows 32 bit machine.
But now when i run the report the report is running only for the default value(Server Variable) which is specified to the prompt. when i change the date there is no effect to the report.
When i drill down to the report i found that the date column(is prompted) is changed to teh server variable name which is might be the cause.
any input on this???

Problem with passing date parameters in cursor

Is there any problem in passing date parameters and like clause as below
CURSOR eftcursor(start_date DATE, end_date DATE, where_clause varchar2) IS
select * from r_records
where created_date between start_date and end_date and description like where_clause;
and in the open statement
select to_date('01/06/2010 00:00:00', 'dd/mm/yyyy hh24:mi:ss') into startDate from dual;
select to_date('01/07/2010 00:00:00', 'dd/mm/yyyy hh24:mi:ss') into endDate from dual;
str := '%something%aaaaa%';
open eftcursor(startDate ,endDate , str);
Do i need to do any kind of conversion in the cursor where clause or when i am passing the parameter in open statement.

Almora wrote:

You might consider whether you really need an explicit cursor though. An implicit cursor is easier to code and performs better.

Passing data b/w applet and apache server

Hi all,
I have an application that runs in the JApplet.I have to pass data b/w server and applet.The
datas are brought from the server using php to the browser and passed to applet using param
tags.
1.Is it possible to set value for the param tag from applet?
2.How to retrieve data from the param tag to the applet in the form of an array.
In the getParameter it is required to specify the param name.
Is it possible to retrieve data from param tag similar to that of getting data from command
line arguments array.

1.Is it possible to set value for the param tag from
applet?Why do you ever want to do it? It sounds like setting arguments passed to a program's main method from command line after the main method has been invoked. It is possible though to dynamically set any values for any applet params using php before the applet gets loaded to the browser window as you generate an html file on the server side.
2.How to retrieve data from the param tag to the
applet in the form of an array.
In the getParameter it is required to specify the
param name.
Is it possible to retrieve data from param tag similar
to that of getting data from command
line arguments array.You can use some naming/numbering convention for your params. For example settings1, settings2 ... Then you can loop in your code retrieving the values like getParameter("settings" + i) checking to see that it is not null or empty.
However, if you don't want to reload the applet (together with the page) just to get some new data from the server, you can establish a tcp/ip connection as elchaschab recommended.
Cheers!

Problem in passing data from one .jsp page to another .jsp page

i have a problem here
Actually i have 2 jsp pages. What im trying to do here is actually i want to pass data from the first jsp page to the second for updating
The first jsp page contains data that user wants to update in the form of table.
<td><img src = "edit.gif" alt = "edit" border="0" ><td>
<TD><%= Name %></td>
<TD><%= rs.getInt("Age") %></td>
<TD><%= rs.getString("Gender") %></td>
So this page displays the data that users wants to update plus one image button (edit button). So when user clicks this button, all the data in this page will be brought to the second .jsp page called updatePersonal for updating.
The problem here is that it is not displaying the existing data in the second .jsp page.
The second page basically contains forms
<INPUT TYPE="text" NAME="FirstName" maxlength="30" value = "<%=FirstName%>">
Can someone please help me. I really dont know what to do..How do i get the data displayed in the text field that is passed from the first .jsp page..thankx in advance

Please modify below code to:
td><img src = "edit.gif" alt = "edit" border="0" ><td>
-----------------modified code
td><a href="updatePersonal.jsp?FirstName=<%=rs.getString(FirstName")%">&LastName=<%=rs.getString("LastName")%>&Age=<%=rs.getInt("Age")%>&Gender=<%=rs.getString("Gender")%>"><img src = "edit.gif" alt = "edit" border="0" ></a><td>
I'm sure it works</a>
