Export JSP to Excel : Weird problem (Urgent)

Hi,
Sorry for the length of question.
I am facing a bit weired problem while exporting my JSP report to Excel.
I have multiple tables in my JSP page .( Use of Multiple tables is a requirement .).
I am using Struts and Oracle 9i JDeveloper for developement.
I have a button called "Excel" and on its click , I am opening the same JSP page in a pop up and passing reqd. parameters to it using querystring
( sometimes I am keeping the parameters into session as the length is loo large to fit into queryString. )
I am using
response.setContentType("application/vnd.ms-excel");
to transform my JSP page to Excel.
Sometimes, this works fine.
But, mant times this gives error such ( in Windows2000 Adv. Server ) as
"Memory could not be "read"."..with the tile of error-popup as "Excel.exe".
(In Windows NT , it never exports to Excel. Every time it gives "Dr. Watson Debugger" message box.)
In Windows2000 Adv. Server ,
While debugging, I observed that when I click on Excel button, the pop up opens and executes the page and again goes to the start of the page and executes again and thus tries to open the same Excel document.
As we know, we cannot open same Excel document twice. Hence it gives a popup alert that
" The file <filename with its entire path> could not be opened.
There may be several reasons :
You might be trying to open a file which does not exist.
You might be trying to open the file which is already open. ..."
etc.etc. and something like this.
Now, this is totally unpredictable. If I click Excel button, It may open the file in excel and on next try it would give error.
This is quite annoying. I searched on this forum, Google but could not find the solution yet.
I cannot use POI - HSSF . I cannot use userdefined Excel tags as well. as it will require a lot of reqork and unfortunately I don't have that much time now.
Please help me and let me know how would I be able to successfully and predictably export my JSP pages to Excel.
Thanks,
Swipsy.

Hi,

Someone could help me??
thanks a lot

Exporting report to excel encoding problem..

Hi All!
A have a problem about encoding. I have a report and I export it into excel file. Everything is in a way. But unicode characters is not written in correct encoding. And I use encoding type everywhere "UTF-8"
I use contentType as
<%page contentType="application/vnd.ms-excel;charset=UTF-8" pageEncoding="UTF-8"%>
and print out as
StringBuffer sb = new StringBuffer();
JspWriter writer = pageContext.getOut();
writer.print(sb);
...Please help me. I couldn't solve this problem.

Hi
Actually i have been doing a lot of experimentation in this for past some days.
The various alternatives are as follows:
a> DESFORMAT=SPREADSHEET attribute in case of Oracle 10g Release 2, in this case the formatting will be maintained but the report will consist of empty cells and merged cells which is not required.
b> in case of Oracle 9i, the following link may be helpful to you http://download-west.oracle.com/docs/cd/B14099_15/bi.1012/b13895/orbr_paptoexcel.htm#CIHFDJAJ . But in this case ,also the problem of empty cellas and merged cells cannot be removed.
c> the option which i have preferred is to use the tool rep2excel which is easily downloadable from http://www.lv2000.com/. With some minor changes in the report formatting u will get the desired output. You may inclde the scripts given in the manual to include the software in your normal execution. The problem of empty cells and merged cells can also be removed.
For any further queries of how to use the tool do feel free to ask

Excel Download problem - Urgent please

Hi All,
I am using 4.6C version.
The user is downloading the ALV output to excel from the output menu
List > Save > File > Spreadsheet >
User tried saving a file to the Local drive and got a "Disk is full" error.
User realized that the export didn't complete (Partial download)
because there wasn't enough disk space to export the report.
User stated that if he had received an error message of some sort, he might have realized the problem.
He didn't receive any kind of errors.
User would like some kind of error message to come up in those situations.
Without an error message, he assumes the reports are acurate and trusts them.
<b>I have analysied and found a exit EXIT_SAPLGRAP_001 which triggres after the popup asking the file path. However this exit doesnot give me the file path</b>.
After this i think i can make use of the class CL_GUI_FRONTEND_SERVICES and method GET_FREE_SPACE_FOR_DRIVE and FILE_GET_SIZE to check for disk space full.
Kindly let me know how to get the file path given in the popup to get it in the exit EXIT_SAPLGRAP_001. Also there was no parameter id for the field.
Thanks for your help.
Senthil

Senthil,
"However in this case the sap didnot uses GUI_DOWNLOAD to download instead it uses download FM. "
What "download FM" is 4.6 using then?
The GUI_DOWNLOAD does check for a disk_full situation... I find it hard to believe that SAP made an oversight here.
I believe that the user is not telling the truth to you... or something else happened in that they have not conveyed to you.

Export to Excel formating problem

I am having a problem with the formatting of a an export file
to Excel, which is created by a Coldfusion page. My export file
contains numbers that need to be formatted as text. I found the
style code below on this forum, but I am not having any luck with
it. I tried adding it to my style file or directly as style
formatting on the export page, but neither one of the two are
getting recognized.
Is there anything else I need to code before this works? Your
help is greatly appreciated. Thanks,
Rose
<html>
<STYLE TYPE="text/css">
TD {
mso-number-format:\@;
</style><body>

<cfcontent type="application/vnd.msexcel">
<cfheader name="Content-Disposition" value="inline;
filename=export.xls">
<cfquery name = "getclub" datasource="#DSN#">
Select mail_name name,…
</cfquery>
<table width="200" border="2">
<cfoutput query='getclub'> <tr>
<td>#customer#</td>
<td>#dateformat(begin_date,'mm/dd/yyyy')# -
#dateformat(end_date,'mm/dd/yyyy')#</td>
</tr></cfoutput>
</table>

Could it be a case sensitivity issue? I also noticed that you
are missing a <head> tag pair, and that your date range field
is not actually numeric. I doubt that excel is that delicate when
it comes to those issues, but you might try:
<html><head>
<STYLE TYPE="text/css">
TD.number {
mso-number-format:\@;
</style></head><body>
<cfcontent type="application/vnd.msexcel">
<cfheader name="Content-Disposition" value="inline;
filename=export.xls">
<cfquery name = "getclub" datasource="#DSN#">
Select mail_name name,…
</cfquery>
<table width="200" border="2">
<cfoutput query='getclub'> <tr>
<td class="number">#customer#</td>
<td>#dateformat(begin_date,'mm/dd/yyyy')# -
#dateformat(end_date,'mm/dd/yyyy')#</td>
</tr></cfoutput>
</table>
</body>
</html>

FR Studio: HTML export to Excel formatting problem

Hey,
I am having trouble with the formatting when exporting from FR Studio to Excel.
I have a report with 2 seperate grids. In HTML and PDF format it looks very neat. But when I export it to Excel, the bottom grid changes its format and some cells have weird colours and borders appear out of nowhere and make it look very ugly. Is there a way to solve this? I have tried many different things including changing cell borders and deleting entire grid and putting in a new one.
Can anyone help me?
Thanks!
Samantha

one can never have control on formatting of exported excel.
At max what can you do is- try different different colors, which look nice in html, pdf as well as excel.
Thanks,
Rahul

Problem while exporting data to Excel sheet.......

Hi
I have written the following code to export data to excel sheet...
data:
       conv_out TYPE REF TO cl_abap_conv_out_ce,
       content TYPE xstring.
data : itab_slsrl type table of znslsrlitm.
data: xml_out TYPE string.
Data:
Node_slsrl type ref to If_Wd_Context_Node,
Elem_slsrl type ref to If_Wd_Context_Element,
Stru_slsrl type ref to if_wd_context_element .
call transformation ('ID') source tab = itab_slsrl[] result xml xml_out.
CALL FUNCTION 'CRM_IC_XML_STRING2XSTRING'
EXPORTING
INSTRING = xml_out
IMPORTING
OUTXSTRING = content.
conv_out = cl_abap_conv_out_ce=>create( encoding = 'UTF-8' ).
DATA: lv_filename TYPE string.
conv_out->convert( exporting data = xml_out IMPORTING buffer = content ).
cl_wd_runtime_services=>attach_file_to_response(
i_filename = 'Sales_order_release.xls'
i_content = content
i_mime_type = 'application/msexcel'
i_in_new_window = i_in_new_window
i_inplace = i_inplace ).
But when i am trying to export data to excel sheet i am getting
following error...
"Switch from current encode to specified encoding is not supported"
"<?xml version="1.0" encoding='utf-16"?>"
if i change encoding utf-8 to utf-16 in my code its giving dump..
"The conversion of certain code pages is not supported"
Did i miss any step...?
How to resolve this problem please help me....
Thanks & Regards
Sowmya.....

Hi Sowmya,
I do had a similar issue, but I avoided that problem temporarily by commenting the following code.
    l_conv_out = cl_abap_conv_out_ce=>create( encoding = 'UTF-8' ).
attach the first file
l_conv_out->convert( exporting data = l_xml_out IMPORTING buffer = l_content ).
Once this is done, you can export the data to Excel and open it and see too...But this is a temporary solution only. Implement this solution to get to understand more flaws of this.

Problem in exporting data to excel in nwds 7.3

Hi All,
I was using the following code for exporting data to excel in NWDS 7.3
private IWDCachedWebResource getCachedWebResource(byte[] file, String name,
WDWebResourceType type) {
IWDCachedWebResource cachedWebResource = null;
if (file != null) {
cachedWebResource = WDWebResource.getWebResource(file, type);
cachedWebResource.setResourceName(name);
return cachedWebResource;
I was getting the error in the following line cachedWebResource = WDWebResource.getWebResource(file, type); when I clicked the quick help it ststed the getWebResource method is depricated. Kindly provide some assistance on what is the new method in its place.
Thank you
Regards,
Preet Kaur

Hi Ganesh,
Thanks that worked fine, but when we go further we are facing problem ie
byte[] excelXMLFile;
IWDCachedWebResource cachedExcelResource = null;
String fileName = dataNode.getNodeInfo().getName() + ".xls";
try {
// create Excel 2003 XML data as a byte array for the given context node,
// attributes and headers
excelXMLFile = toExcel(dataNode, columnInfos).getBytes("UTF-8");
// create a cached Web Dynpro XLS resource for the given byte array
// and filename
cachedExcelResource = getCachedWebResource(
excelXMLFile, fileName, WDWebResourceType.XLS);
// Store URL and file name of cached Excel resource in context.
if (cachedExcelResource != null) {
wdContext.currentContextElement().setExcelFileURL(
cachedExcelResource.getURL());
wdContext.currentContextElement().setExcelFileName(
cachedExcelResource.getResourceName());
// Open popup window with a link to the cached Excel file Web resource.
openExcelLinkPopup();
} else {
wdComponentAPI.getMessageManager().reportException(
"Failed to create Excel file from table!", true);
} catch (UnsupportedEncodingException e) {
wdComponentAPI.getMessageManager().reportException(
e.getLocalizedMessage(), true);
} catch (WDURLException e) {
wdComponentAPI.getMessageManager().reportException(
e.getLocalizedMessage(), true);
The above bold lines also would need to be converted to inputstream, but not sure how to correct that
We are following the below pdf for the implementation.

Problems Exporting rpts to Excel!

CA Forum: Exporting
Hello Everybody! I´m new in the forum, and i have a question that is killing me... I´ve an application that runs asp and COM+ using Visual Basic... I made another litlle module for Crystal Reports rpts imports... I wrote the code using the Business Objects Samples like example (rtpserver.asp, etc) ands works fine. The problem that i´ve found is: In the export all the options are working, except the 2 excel´s types. When a try do export a report to Excel, i put the file name and try to save, but the application hangs my IIS server... Anyone can help me? I´m using Windows XP SP2, Office 2003 and Crystal Reports XI R2...
Tahnk´s

Wannetta,
When the user filters the data and then exports it to excel; all of the original data is exported rather than the filtered data.
Can you describe the exact workflow in a bit more detail. Here is one "gotcha" to consider, which sounds suspicous to your case. If the user is using InfoView (not WebI), and he or she uses Export to Excel with CSV, then there is no consideration to what has been done in the report, the contents of what you see in the "Results Object" panel from the Edit Query view is what is sent over to the CSV file. Also, the order of the columns of data is according to what is specified in the "Results Object" panel. So, just a heads-up to consider if this is happening or not. Otherwise, please give us the workflow and the version of XI and client's versioin of Java on the workstation...
Thanks,
John

Missing data when exporting webi to excel (not 65536 limit problem)

Hi guys
I just meet a problem about webi that it will miss data when exporting webi to excel.
It's not about 65536 limitation, as my webi report do some aggregration and limitation and never beyond that limitation.
Also there are 2 tabs in my reports, if I split the 2 tabs into 2 separate reports and export them separately, then problem disappeared.
Any ideas on this?

Hello Claes

Tools => Import and Export => Specifying the Sequence of the External Data Structure => External File Structure: Specification
Table EST07 should be part of export file. I am not sure if the packing requirement ist part of EST07.
Furthermore wirh ECC 6.0 EnhPAck3 some changes happend generally in the area of DG classification.
E.g. Dynamic dangerous goods classification. I am not sure if these changes are "included" in some sense in the EH&S data download.

Export data from JSP to Excel on click on button

Hi,
I want to display the table data in my Jsp to Excel on click of "Export to Excel" icon, The data in my jsp table is dynamic, only click of "export to Excel" icon i want the contents of the table needs to be exported to Excel. Can pls anyone help me in doing this..
Thanks & Regards
Sowmya.J

On click of the button, you will have to reuse the same java code which you used to populate the table in the JSP except that you will have to create an excel file with the data you got using suitable excel api's (look for POI api). Write the stream to the response and the browser will take care of opening a dialog to save/open the file.
