Excel file download in jsp

Hi,
Is it possible to download excel file on the server on a JSP page. Kindly advice.
Thanks in advance.

yes...
What is the scenario....
is it..
1. You have a XLS on server...alredy created..
2. Now you need a link on JSP page....that is linked to this EXS file...
3. User acess your web application and click on link....
4. A popup comes up....and user selects either to save or download the file....
Is this your scenario....
If not then specify steps you are looking for....and you face issue in which step....

Opening Excel files from a JSP page

Hi,
I am not able to open up an Excel file through JSP.
I am using following code snippet in JSP page
response.setContentType("application/vnd.ms-excel");
response.setHeader("Content-Disposition","inline; filename=Test.xls");Do i need to do additional settings for rendering Excel from a JSP
Thanks in advance !!!

Hi,
In my application , we have Excel files on the server i.e we are not creating excel sheets.
I just want to display these static excel files through a jsp.
I am able to display the excel files by reading them into ByteArrayOutputStream
<%
response.setContentType("application/vnd.ms-excel");
response.setHeader("Content-Disposition","attachment; filename=B.xls");
ServletOutputStream so = response.getOutputStream();
String filename = "D:\\Test.xls";
String mimetype = "application/vnd.ms-excel";
ByteArrayOutputStream output = new ByteArrayOutputStream();
InputStream in = new BufferedInputStream(new FileInputStream(filename));
byte bytebuff[] = new byte[500];
for(int lengthread = 0; (lengthread = in.read(bytebuff)) != -1;){
output.write(bytebuff, 0, lengthread);
byte data[] = output.toByteArray();
response.setContentType(mimetype);
so.write(data);
in.close();
so.close();
%>But my question is that , do i really need to do all this for rendering excel through a jsp.
Can't i do it by just setting the content type ?
Thanks

Problem making an Excel file from a jsp

Hi.
I'm developing a web application that uses Excel for printing the reports. So far everything has worked fine, at least for the created Excel files that do not have any images on them. Now I need to create an excel file with an image as the header. I tried adding the necessary code to include the image, but when I open it, the image is not displayed (like when you open an HTML page that could load a certain image). I tried using different ways to set the src to see if maybe the path was the problem, but everytime I got the same result...
How can I do this? How can I include the image and actually display it when the user opens the file in Excel?
Thanks in advance

Excel file download issue

Hi Experts,
I am downloading an excel file which is stored at the MII server using JSP file. I am using the below code for the same. I am able to download the excel file successfully but when I open the same I get some junk value as content. I mean to say the content is not at readable format. I have tested the java code using standalone program where it worked successfully.
I tested this JSP at MII 12.2 and MII 14.0 and both provided same result. I have attached the screenshot of excel how it looks after opening
I want to know is this a problem with Netweaver web server?. I mean the way it runs JSP. Unfortunately I could not test this on another web server
Any help on this is very much appreciated.
<%
String filePath = "C:\\myfile.xls";
try
FileInputStream in = new FileInputStream(filePath);
response.setContentType("application/vnd.ms-excel");
response.addHeader("content-disposition","attachment; filename=" + filePath);
int octet;
while((octet = in.read()) != -1)
out.write(octet);
in.close();
out.close();
catch(Exception e)
out.println("Exception occured:"+e);
%>
Thanks
Shaji

Hi Christian,
Thanks for your response.
I tried that as well but same result. I get a alert message as below while opening the file.
"Excel cannot open the file Demo.xls because the file format or file extension is not valid. Verify that file has not been corrupted and that the file extension matches the format of the file"
I am trying to run the same file on another web server such as tomcat and see if the issue persist.
Thanks

Download the Open G Toolkit from www.openg.org. There is a VI called Quit Application.vi that works great. I have used it with the very stupid Brooks 0154 SmartDDE Controller program to reset the application.
Be sure to save the document and close the DDE communication first.

That's fine, but you can serve up an Excel file (for download) with a couple lines of code. That doesn't require Spring. Too often I see these noobs working on a web project and throwing half a dozen frameworks at it because people told them to or recommended them. Noobs don't often know better and I have no doubt that some of them would attempt to use Spring just to get an Excel file to download if they were told to.

Excel File Download and Drop downs at Column Level

Hi All,
I am able to download the excel file, but I want to include dropdowns for each column. So that using those values user can add new records using the drop down list values.
I am thinking it is not possible. Can some one validate me..?
I have another approach.
I will download masterdata and the Filedata to the excel and later i will create the relation to show the listbox. But i am not able to download(add the tab) to the existing Excel file. In short is it possible download the multiple files into a single excel file, with different tabs.
Thanks and Regards
Vijay

Hello,
As you wanted to include dropdowns for each column, it is possible in two ways.
Way1: Statically
Create a View element with type Dropdown by key as one of the table column -->bind the property 'Selected Key' to the required attribute(Since attribute type will be specified to be the data element and within domain can have Fixed values --> The table column would be automatically displayed with dropdown entries.
Way2: Dynamically
In the WDDOINIT method of that view where you have dropdownkey element has located -->Write the following code
DATA:    lo_node_info             TYPE REF TO    if_wd_context_node_info.
lo_node_info->set_attribute_value_set(
    EXPORTING name      = 'Attribute_Name'
              value_set = lt_value_set ).
lt_value_set shall be populated with the data that you wanted to display in the dropdown.
Thanks,

PDF files download as JSP

I just upgraded to Leopard 10.5.6 this weekend from Tiger 10.4.11 then upgraded to 10.5.8. All went well except for a small glitch in Mail which I got fixed with the help of this forum. My newest problem is this morning I went online to my bank to download our monthly statement which always is in PDF format. The file downloaded fine, except the file title says it's a PDF, but the extension is .jsp. I contacted the bank and they have changed nothing so I am wondering is there a setting I need to change somewhere that would affect the download? At present I haven't found an application that will open .jsp files, but first I want to get them back to PDF format. Any suggestions will be appreciated.

Have you tried renaming the file so that its extension is ".pdf"? I believe I regularly download PDF files that have "jsp" in the file name, but renaming them corrects the problem.

Help Regarding excel file download

Hi,
I have developed a object with alv list display aand in the selection screen maintained a checkbox for EXPORT TO EXCEL..
and for each and every field in the field catlog wriiten the code like
IF P_EX = 'X'.
      LS_FIELDCAT-ROW_POS    = '1'.
      LS_FIELDCAT-COL_POS = 1.
But this output is not flowing into excel file when executing...can anyone help me how to download the output data into excel file when we execute.because this report runs in the background and after execution data should be flown into excel file.
Regards,
Venkat.

Hi Venkat,
use this Function module to download the file
CALL FUNCTION 'GUI_DOWNLOAD'
    EXPORTING
      FILENAME                        = 'C:\Documents and Settings\sap\Desktop\Hierarchy.xls'
   WRITE_FIELD_SEPARATOR           = '#'
    TABLES
      DATA_TAB                        = gt_target.
Here gt_target is the internal table which holds the data.
Hope this solves your purpose...
