Passing data from servlet to excel sheet

i am learing servlet and JSP.It ll be of great help if i get an idea about passing the data got from JDBC from a servlet to excel sheet.

Some terms that you can start Googling for:
JDBC: JDBC is the standard API for Java applications to read/write data from MS Access database (or any other DBMS).
Jakarta POI: This is one of the tools to generate dynamic Excel files on-the-fly.
And of course, you're familiar with Servlets, right? ;)

describe table itab lines wk_records.
LOOP AT ITAB.
at first.
**Provide path
concatenate 'C:\' wk_file_name Wk_EXT into wk_path.
open dataset WK_path for output in text mode encoding default.
if sy-subrc 0.
write:'ERROR while opening dataset !!!!!!'.
EXIT.
endif.
CONDENSE wk_path.
**Heading Part
concatenate 'Part No' 'Description'
     into wk_string separated by cl_abap_char_utilities=>horizontal_tab.
endat.
**Data ITAB
CONCATENATE ITAB-MATNR itab-maktx into wk_string
     separated by cl_abap_char_utilities=>horizontal_tab.

Pass data from servlet to jsp using sendRedirect

Hi,
I am passing data from servlet to jsp using forward method of request dispatcher but as it doesn't change the url it is creating problems. When ever user refreshes the screen(browser refresh) it's re-loading both servlet and jsp, which i don't want to happen. I want only the jsp to be reloaded.
Can I pass data from servlet to jsp using sendRedirect in this case. I also want to pass some values from servlet to jsp but without using query string. I want to set some attributes and send to jsp just like we do for forward method of request dispatcher.
Is there any way i can send data using attributes(without using query string) using sendRedirect? Please let me know

sendRedirect is meant as a true redirect. meaning
you can use it to redirect to urls not in your
context....with forward you couldn't pass information
to jsps/servlets outside your own context.Actually, you can:
getServletContext().getContext("/other").getRequestDispatcher("/path/to/servlet").forward(request, response)I think the issue here is that the OP would like to have RequestDispatcher.forward() also update the address in the client's browser. That's not possible, AFAIK. By the time the request is forwarded, the browser has already determined the URL of the servlet, and the only I know of way to have the browser change the URL to the forwarded Servlet/JSP is to send a Location: header (i.e. sendRedirect()). Remember that server-side dispatching is transparent to the client. Maybe there's some tricky stuff you can do with JavaScript to change the address in the address bar without reloading the page?

How to Save Data from DataGrid to Excel Sheet?

Hi All,
I am trying to use Adobe Flex 3.0 for making web pages.
I want to save the data from DataGrid and Advanced DataGrid of Adobe Flex 3.0 to Excel Sheet file. I am trying Flex Help, but didn't find answer for it.
In the application there is a button for 'save' by pressing which the 'Save As' window should appear.
And giving the path to the '.xls' file, the data from DataGrid should be saved on that location in .xls format.
This is my requirement.
If anybody knows how to do this please help.
Thank You,
Sharad

Hi
Using document.applet.saveAsCSVFile(); code you can not get data in proper format.
For one of my application i have stored the data from Grid to excel.
But i am not sure about Adobe Flex 3.0, my code will work or not.
Also you need to make the "Initialize and Script Activex Control Not marked as Safe" as enabled in your IE.
You can share ur email. So that i can send the code. Here I am not able to paste the code.
Thanks

Hi,
You shouldn't use DataAttributeInfo as it is an internal object, if I'm correct.
Use IWDAttributeInfo instead of DataAttributeInfo and it should work
(See also API doc of IWDNodeInfo.iterateAttributes() at http://help.sap.com/javadocs/nwce/ce711sp02/wdr/com.sap.wdr/com/sap/tc/webdynpro/progmodel/api/IWDNodeInfo.html#iterateAttributes())

Pass data from servlet to EJB3 and backward

Hello All,
The distributed application is being developed by the following scheme:
J2EE Application Server (JBoss) - Servlet container (JBoss's contained Tomcat) - RIA client (Flex)
Application server needs to handle client's requests and provide backward connectivity also.
Servlets in this scheme are required by the BlazeDS library which is implemented as set of servlets handling HTTP requests from the clients.
This forces us to:
- invoke EJB from the servlet while handling client's requests.
- invoke servlet from EJB for the sake of providing the client with urgent messages which need to be displayed immediately.
The easiest ways to achieve that I am aware of are:
- servlet invokes EJB via JNDI lookup (inefficient?)
- EJB invokes servlet by passing HTTP request to web server (inefficient!)
Is there standard and efficient ways to wire servlets(JSP) and EJB in either directions?
Thanks,
Alex.

Hi Chicon,
Thanks for advice. Probably I need to add few more words to make the question clearer.
Chicon wrote:
It is not the role of an EJB to fire a servlet. EJB's are only modules.
In your case, the EJB invoked should pass the necessary data to the servlet. From the data it receives, the servlet has either to build and to send the HTML document(or other formats : pdf, txt, xml,...) or to fire the appropriate JSP to the client. The servlet may also call a more specific servlet to do the job, e.g. in a Struts like framework.- Invocation of EJB from servlet is one data flow direction. After EJB is invoked and finished, servlet gets results, makes its own job and sends data to clients either in html or binary AMF (Flex proprietary) format.
- Invokation of servlet from EJB is another data flow direction. It will be employed, when server decides to inform all interested clients about an urgent event. Client are not asking for that event explicitly, but they are ready for handling such messages from the server.
Of course, in order to achieve this, there is a need in a channel between server and each client. This is what BlazeDS for.
The first requirement could be satisfied by either JNDI lookup or (as malrawi proposed) by dependency injection.
The second one is a little bit harder... It may involve any other mediators, not necessarily the same servlets.
I am looking for the best suitable solution now.
Thanks,
Alex.

Problem while opening data from mysql in Excel

Hi friends
when i try to download data from MySQL to excel sheet I am getting error of
This file is not in a recognizable format.
. If you know the file is from another program which is incompatible with Microsoft Office Excel,click Cancel then open this file in its original application.If you want to open the file later in Microsoft Office Excel,save it in a format that is compatible,such as text format.
etc

hi,
there are some specific restrictions in downloading data in alv.
i.e you cannot have morethan 1024 characters that can be downloaded in single row.
so change your report columns accordingly.

Query Data From Oracle to Excel

Dear all,
Please guide me to solve.

Question's Caption is : Data From Oracle to Excel
While you are asking :
data in execel (windows ) move to Oracle Database table (Linux *64)Anyway, if your question is export data from Excel to Oracle then below thread may be of your interest which are saying that you have to install Dg4ODBC on Windows and use the ODBC driver there.
When running DG4ODBC on Unix you need an ODBC driver on this Unix box which can connect to the MS Excel file. I'm not aware of any suitable driver so far that fulfills the ODBC level 3 standard required for DG4ODBC.
So instead of using DG4ODBC, get the Windows software of DG4ODBC and install it on a Windows machine. You can then connect from your Oracle database to the Dg4ODBC listener on Windows which then spawns the DG4ODBC process. This DG4ODBC process then uses the MS Excel ODBC driver to connect to the Excel sheet.

Export data from forms to excel

HI
In my application im trying to export data from forms to excel.Everything works fine.First of all im using get_file_name for selecttion of file and passing it to ole2 package as follows
FILENAME := GET_FILE_NAME(File_Filter=> 'XLS Files (*.xls)|*.xls|',dialog_type=>SAVE_FILE);
     ARGS:=OLE2.CREATE_ARGLIST;
     oLE2.ADD_ARG(ARGS,Filename);
     OLE2.INVOKE(WORKSHEET,'SAVEAS',ARGS);
The problem is if i select an existing file the get_file_name itself raises one message ".....file already exists Replace an existing file?"
Similarly the excel also also raises the same message "".....file already exists Replace an existing file?".I want to suppress atleast one of them? Could anyone help for this problem?
appreciate ur help
THANKS

Looks like...
ole2.set_property( ex_app, 'DisplayAlerts', false );
where "ex_app" variable Excel Application -
     ex_app:=     ole2.create_obj('Excel.Application');
and more Question:
When i close excel app - in process viewer i see "excel.exe"
ole2.release_obj don't work :(

Extract data from Oracle in excel file

Hi,
I have a requirement where in I need to extract data from Oracle in excel file and the excel worksheet name should be "Data".
for eg. excel file name "AR Data_DDMMYY" and excel worksheet name "Data"
I have used the UTL_FILE API to extract the tab delimited data which can be opened in excel but it is not exactly an excel file as the worksheet name is same as the file name.
I tried using utl_file.fcopy and frename.
Is there any way to do this using PLSQL?
select * from v$version;
Oracle Database 10g Enterprise Edition Release 10.2.0.5.0 - 64bi

end loop;
utl_file.fclose(f);
--utl_file.frename(dir, file_name, dir, replace(file_name, '.xls', '_')||to_char(sysdate, 'MMDDYY')||'.xls', false);

Hi,
I was able to generate the excel 2007 file with the data using the package from below link;
http://technology.amis.nl/2011/02/19/create-an-excel-file-with-plsql/
but the requirement is to generate excel 2003 file.
I tried changing the .xlsx to .xls and it gives a note while opening the file "The file you are trying to open, abc.xls, is in a different format than specified by the file extension. Verify that the file is not corrupted and is from a trusted source before opening the file. Do you want to open the file now?"Then you have three options:
1) stop using anton's package and find another one that supports the old and deprecated version of Excel 2003
2) write your own package to produce an Excel file.
3) Upgrade your version of Excel to a recent version
I tried the programs from other links on the forum but I am still getting this message. The client does not want this message to be displayed as the excel file works as an input to another system.
Can anyone help me with the issue?
Also, is it true that the programatically generated excel file is actually an xml file which is renamed to .xls and hence it shows the message while opening such files?Yes, Excel supports several different formats for it's files. By default, if you save an XLS files from Excel, it writes it out in a Microsoft proprietary binary format, which you would be hard pushed to replicate easily from PL/SQL. Excel also has the ability to save it's files as XML format, which is more readable and easier to produce programatically, whilst still allowing you to have multiple sheets, formulas and formatting included in it. That's the format that most people who need formatting and multiple sheets opt for when programatically generating their data as excel workbooks. (There's also an SLYK format that people used to use before that, but it's not as flexible)
If you want to write your own, the easiest thing to do is to start with a blank workbook in Excel, and put in your basic requirements e.g. a couple of named sheets, and some data in different formats (number, date, text etc.) and different formatting options etc. Save that file in XML format from Excel and then open up the file using notepad/wordpad to look at the structure. There'll be a whole load of redundant rubbish Microsoft put in there, but you should be able to figure out the basic structure of XML required to give you what you want.

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>

How can I pass data from a form guide to another form in a business process

How do we pass data from a form guide to another form(not necessarily a guide) without having to open the form. For example we have a small form guide to capture the contract id so we can then get data from contracts table to present to the user in a form. We want the user to open the guide (either Flex guide or form guide) to enter the contract id. Upon submission we want the process to get the contract data and put it into the form that will be opened at the next step by the user without having a user interact with the form to get the data into it. In other words we need the process to get the data and populate a different form than the form guide the contract id was entered in and this new form needs to be opened in the next step by the user.

Firstly, I'm assuming that you have a Forms ES Server if you are rendering a Guide. This could be either version ES1, ES2/2.5 or ES3/ADEP
If you submit the form back to the server, you can populate a second (PDF/XDP) form with the data bound to the same schema/Data Model using Forms ES.
You referred to the next user in the chain - If you are using Process Management, this is very easy, as you define what form is used to render the data in the "Presentation & Data" section of the Assign Task activity

Certainly it is unusual that you can still see the tables available in your MS Access database but cannot see the columns? I am assuming you are configuring an Open Statement step and are trying to use the ring-control to select columns from your table?
Can you tell me more about the changes you made to your file when you 'changed' it with MS Access? What version of Access are you using? What happens if you try and manually type in an 'Open Statement Dialog's SQL string such as...
"SELECT UUT_RESULT.TEST_SOCKET_INDEX, UUT_RESULT.UUT_STATUS, UUT_RESULT.START_DATE_TIME FROM UUT_RESULT"
Is it able to find the columns even if it can't display them? I am worried that maybe you are using a version of MS Access that is too new for the version of TestSt
and you are running. Has anything else changed aside from the file you are editing?
