Export to Excel & Download in JSPDynpage

Hi All,
I have developed one JSpDynpage application in which I am displaying the custom portal activity report on portal page. I . I have used normal HTML code in JSP file. Now I have to export this data in Excel sheet & Download it.
For this I have gone through these steps.
1) As per the few suggestions on SDN , I have created seperate AbstractPortalComponent for this functionality.
2) I have followed prakash's blog i.e. Create an excel file from JAVA using HSSF api
3) Included all needful POI jar files mentioned in the blog.
But still i am getting error - java.lang.NoClassDefFoundError: org/apache/poi/hssf/usermodel/HSSFWorkbook
This class exists in JAR file when i checked. Error is looking simple, but not getting resolved.
Also please suggest me -
1) How to call this AbstractComp. from JSP file , when user click on a link on portal page.
2) what shoud be the additional code for download functionality?
Any sample code will be more helpful
Regards,
Vishal

Hi Vishal,
I am facing one problem with customization of portal activity report.
We made some changes to the existing report par file and deployed from NWDS to dev system. When we previewed the existing iview in Dev portal system the changes reflected and once we exported the PAR file to QA system and previewed the iview from portal, there is no data coming to portal.
Can you please let us know what could be the reason for this?
Thanks

Numbers get exported as Text when selecting Download to Excel / Download to

I have a dashboard report in which the numbers appear in the French format as follows:
37 167 534,4
In English format, it would represent
37,167534.4
When i export my report, the number is displayed in Excel as text, and not as a number. This is because of the space in between37 and 167 in the French format.
What changes do i make to ensure that the number is exported as a number, and not as text?
I'm using Office 2003 SP3. Need a solution ASAP.

Hi,
You can try adding the below statement in the Custom CSS section of the column properties:
mso-number-format:"\@"
fyi..:
refer my o/p screen short:

the above one works for excel download with % symbol

Issue with export in Excel in WAD

Hi
I have an issue with export to excel in WAD. I have a web template with two or more tabs.
On the webtemplate I have two buttons to export to excel. One to export the content from the active tab and one button to export content in all tabs.
My problem is that when I export to excel it always add the current/active content twice. I've tried with both buttons and they work as expected except that they export one table to much (the active).
can anyone help / give a clue what to look for.
br,
John

Hi

Hi,
You can also try in this way
in the output screen
click List (in app tool bar) -> Export -> Spreadsheet
and save at your desired location.
(It will be save in .mhtml format , just rightclick on it and you can open it with excel )
Then you will be able to view in your required format.

Export to excel and others inactive in ALV GRID

Hi,
I am creating a report using the 'REUSE_ALV_GRID_DISPLAY' FM and the export to excel fucntionality is inactive. There is no spreadsheet push button on the application toolbar and the List->Export sub menu items 'Word processing' 'spreadsheet' and 'local file ' are all inactive. I have tried to run the code on a different system and the export to excel functionality works there. I am considering creating a new GUI staus using the standard status contained in the function group of 'REUSE_ALV_GRID_DISPLAY' but will like to know if this issues can be remedied e.g is it probably a basis issue or a configuration issue e.t.c.
Thanks
Andy.

Hi Max,
Checked the PF_STATUS_SET routine and there was code that deactivated all gui download function codes of the standard gui status if an authorisation check failed ( auth obj. S_GUI) but the function code for excel export is &XXL not &VEXCEL.
Thanks for the prompt reply max, much appreciated
regards
Andy.

Running report with alv grid in background and exporting to excel

Hi Guys,
              I've created a report program that uses the alv grid. When I run the report in foreground, I can easily export it to excel. However, if I run it in background, then display the spooled report and try to export to excel, it does not put it in excel format (seems to go over as one big column rather than individual columns that are defined in the report). Is there a way to run it in background ,export to excel properly and i have to email also in Excel sheet format.?
Thanks,
Gopi.

In background u cannot do a download to excel. you can do is create CSV format file
or
write a report for output with tabs then call that report using
submit yXXXX exporting list to memory
           and return.
call function 'LIST_FROM_MEMORY'
    tables
      listobject = report_list
    exceptions
      not_found = 1
      others     = 2.
and send the report_list to email users

Export to Excel Issues

We just upgraded from Crystal 8.5 to Crystal 10. When we export to Excel, the formatting is terrible. We have close to 100 reports that we routinely export...some with 40,000 rows. To try to fix these once they're in Excel is out of the question.
In previous threads I've been reading about a "patch" that supposedly fixes this. Where can I download this?
Eric Hill

The way reports work and export changed significantly in CR 9. While there was a dll available to help move from CR 8.x to CR 9, that dll is no longer available. Not for CR 9, nor any other versions of CR. Instead, you will have to modify your reports as per the article [Crystal Reports Designer Version 10 Exporting to Microsoft Excel|http://www.sdn.sap.com/irj/boc/go/portal/prtroot/docs/library/uuid/10d3ba69-951e-2b10-3093-e3cf287a57c9?quicklink=index&overridelayout=true].
No other work-arounds or options exist at this time.

Formatting an Export to Excel

Can anyone tell me how to force a column being exported to Excel to be interpreted by Excel as a text field? The column contains only digits, but has values such as '0000' where all four zeroes are to be considered significant.

Thanks for your replies. Unfortunately, enclosing values in quotes won't work. To give you a simple example, imagine the source for an interactive report is:
select '0180' account_code, 145.23 amount from dual;
When the user views the interactive report, they should see 0180 for the account code and 145.23 for the amount...and they do. So far so good.
Now, they click the tool widget and select to download the report to Excel. Here's where the wheels come off. I need the account code to be interpreted by Excel as text and amount to be interpreted as numeric. Anything I apply at the download-level, like enclosing the columns with single quotes will apply to both account_code and amount. I need a granular way to specify formatting on a field-by-field basis, only to be used when downloading the data.

ALV List export to Excel when program is run in background

Hello,
I am running into an issue with a custom ALV report which contains an export to Excel option on the input screen. However, when I attempt to run the report in background due to high volume of records/expected performance constraints, the job fails to produce a spool when the "export to Excel" option is selected. When I deselect that option, the background job successfully generates a spool, which I can then export to Excel (albeit the formatting will not look the same).
Is the above an accurate statement or does anyone know of a way where either;
1) The background job can create and store the Excel output into a cached directory?
2) The spool generated, when exported to Excel, can match the format of the foreground Excel output?
Thanks in advancce.

Check out the sample program of the provided link ..

Project Server 2010 export to Excel 2007 fails

I keep getting the following error when I try to export Resource Availability to Excel. I am using Project Server 2010, Excel 2007, IE8, Windows 7. I have PS set as a intranet site with low security set. Coworkers with the same setup are
not having this issue. I have tried exporting to Excel with Excel open, Excel closed, on a hardwire network connection, on wireless network connection, on my corporate VPN and not on my corporate VPN.
Microsoft Office Excel cannot access the file "URL here" for the possible reasons:
-The file name or path does not exist.
-The file is being used by another program
-The workbook you are trying to save has the same name as a currently open worklbook.
Please provide suggestions on what to try differently to make the export work. I have tried downloaded other version of IE and have the same issue.

Hi Julia,
since nobody jumped in, I'll give a try!
Have you tried to reinstall Excel or at least repair it?
Hope this helps,

Crystal Reports for Eclipse ver. 2 fails on export to excel

I have downloaded crystal reports for eclipse version 2 (full eclipse setup) and created the sample project.
The new version of JRC looks awesome on the browser. Finally the visual appeal is as good as the .NET version.
However I am having a problem with the export to excel feature. When I select export to excel, I get the following exception
Update: I just realized this problem exists for all the export options
SEVERE: Servlet.service() for servlet CrystalReportViewerServlet threw exception
com.businessobjects.report.web.shared.WebReportingException: getOutputStream() has already been called for this response----
(Full Exception pasted below the message)
I have not made any changes to the sample crystal reports project so I am not really sure what i am missing.
I have Microsoft Vista Ultimate with Crystal Reports 2008 trial version installed.
I have configured eclipse with Tomcat 6.0 and JDK/JRE 1.6
Any help would be appreciated.
Thanks

I searched on scn and got the listing you mentioned.
The jsp code I am using is as follows.
<%@ page contentType="text/html; charset=UTF-8" pageEncoding="ISO-8859-1" %><%@ taglib uri="/crystal-tags-reportviewer.tld" prefix="crviewer" %><crviewer:viewer reportSourceType="reportingComponent" viewerName="CrystalReport1-viewer" reportSourceVar="CrystalReport1" isOwnPage="true"><crviewer:report reportName="CrystalReport1.rpt" /></crviewer:viewer>
And I get the following exception on selecting any export.
WebReportingException: getOutputStream() has already been called...
So I think maybe this problem is not the same as listed under SAP Note 1199025.
Also the strange thing is I just download the full ganymede version with crystal report for eclipse version 2, and created a default crystal reports website.
The samples were provided automatically, and I have not written any code myself.
Any help would be appreciated.

2013 Excel WFservlet.xls check exports to Excel and opens blank Windows 7 Ent

HI All,
I am trying to work through an issue involving an online check through Accounts payable downloading to a blank Excel document. If the user saves the file it opens as it should but if she chooses to open it, it opens blank. If I go to View>Arrange
All> leave the Tile selected (basically do nothing but click OK) and click OK it opens. I have done an Office repair with no luck and also a complete uninstall then used the office removal tool then reinstalled with reboots in-between and still no change.
This computer is on a domain and I can get the check to export to excel without any issues on another computer so I know it's not her roaming profile. I can get it to work on my machine and others as me, admin and her but on her machine no luck. I have opened
IE settings on her machine and a working machine and matched the settings exactly as well as Excel settings. I have started Excel in safe mode and exported but no luck. I have disabled all add ins in excel and added the site to compatibility settings and trusted
sites in IE. I reset the browser and deleted history with all options selected.
In the beginning I was receiving the error "The file format and extension of ".xls" don't match. The file could be corrupted or unsafe. Unless you trust its source, don't open it. Do you want to open it anyway?" I checked the following
In Windows Explorer Tools > Folder Options > View tab > made sure "Hide extensions for known file types" was unchecked.
I also did
Open your Registry (Start -> Run -> regedit.exe)
Navigate to HKEY_CURRENT_USER\SOFTWARE\MICROSOFT\OFFICE\12.0\EXCEL\SECURITY
Right click in the right window and choose New -> DWORD
Type “ExtensionHardening” as the name (without the quotes)
Verify that the data has the value “0″
No luck.
If I log into the computer as local admin or my domain account it still opens blank.

The file will open in Chrome but I am wondering if that's because Chrome downloads the file as if I choose to save the file opens fine. I am going to run the OffCAT will post my findings.
Thank you!

Any ideas on how to merge 2 reports on page to export to Excel or PDF?

This is for OBIEE 11g (we are currently running 11.1.1.6.8). We have a user requirement to put the prompt selections on each report that is exported to Excel or exported to PDF. This requirement has to do with auditors. We cannot use the Filter Criteria view because we have saved filters that contain other saved filters so not all of the filters are shown. What the users want is to just have the ability to Export to Excel or PDF for one report and add the prompt criteria so that it also shows in Excel or PDF. We know we can use presentation variables and create a narrative view to show all of the prompt criteria. But we don't want to have this in a view in the compound layout of every report on the page (we have many pages with many reports on them). What we would like to do is have the Export (to Excel or PDF) download the prompt criteria (like when you use the printable HTML and printable PDF functionality only we want this for one report). So think of merging the report that is being Exported to Excel or PDF with another report that is built to show the prompt criteria. Is anyone else doing this kind of functionality? Any ideas on how to do this with javascript?
We created an SR on this to find out if Oracle had some ideas but they did not and said that this is already an enhancement request ( Bug 8242921: ALLOW PROMPTS TO BE DISPLAYED WHEN DOWNLOAD TO EXCEL)
Any help would be appreciated. Marybeth

Did u tried the first method? i.e directly exporting the analysis to excel?
Thanks.
