Portal : JSP : Output in an Excel File.

Hi,
I am unable to get the output on a JSP Page in Microsoft Excel
I am trying to generate an Excel Report from my Portlet. I am picking up the data for the Report from Oracle Internet Directory.
I have created a simple JSP file ( as a Portlet ) and deployed it on Oracle App Server. I then registered a new Provider for the deployed JSP Page and added the JSP as a Portlet in a new Portal Page.
I am trying the following code snippet in the JSP :
<%@ page contentType="application/vnd.ms-excel"%>
I get this weird error :
AbstractResourceRenderer.renderBody - received IOException
java.io.UnsupportedEncodingException: Media Type of a TextResponseWrapper must start with "text/"
If I am correct, Portal should support this feature. I must be able to publish reports to an Excel File.
I am new to Oracle Portal and I find this strange. The JSP page works fine in JDeveloper, but when I access it via Oracle Portal, I get the " UnsupportedEncodingException ".
I posted my question on Metalink and was told to post my question in this forum.
I am not sure if I need to post any other information or Configuration Settings - please do let me know if any other information is necessary.
Thanks,
Sandeep.

Ok,
After many sleepless nights and a long struggle, we were able to arrive at a workaround - simple & something that works.
We created a Servlet ( not a Portlet ) that generates the Excel File. The Servlet is not a Portlet and as such is not restricted in the content-types that it can use. We let the user arrive at this Servlet via a simple HTML link.
Well, that's about it ! I just wanted to post this so that anyone else tearing their hair apart with the same issue can find some solutions.
Still, I strongly feel that a superb product like Oracle Portal should support the various content types.........

Sandeep

Oracle Matrix Rpt output to Microsoft Excel File

I am looking for a solution that would take my current Oracle 9i matrix report output directly to an excel file. I have clients that need to see the report not in a pdf format(which I currently use) but in an excel format.
Thanks,

You could either use:
a) DELIMITED output, assuming that the matrix isn't too large.
b) DELIMITEDDATA output, which will just give you a dump of the data, and you'd need to construct the cross tab directly.
c) In you're using 9i, then you could use jsp tags to output directly into an Excel html file (this could get pretty complicated for a matrix report). See an example of this at http://otn.oracle.com/products/reports/htdocs/getstart/demonstrations/index.html

How to output to an excel file?

Hi,
I have written a program that gets data from the database and I like to find out how to output the data to an excel file. I have read about similar topic on the discussion board and the solution are for the online application. Mine is a desktop application. The user can specify what the destination file is. Can anyone help. Thanks.

The simpliest way is to take your data and write it to a Comma Dilimeted File which Excel can read without any problems or user intervention. You would use an ObjectOutputStream. Hope this helps.

Alv output- download to excel file

Hi
I have ALV report. My requirement is
For example i have 10 records in my ALV output.
I want to download first 5 data to excel file.
so i need to select the data and click the button download in alv screen. I created the download button in ALV screen.
how to write coding for this

Hi Kumar K,
U can do it by feeling another internal table from the final internal table which u displayed...
suppose u want the record 5 to 12 then
LOOP AT itab FROM 5 TO 12.
Append itab to itab2.
ENDLOOP.
So now Itab2 contains record 5 to 12...
Logic:
Create one Custom Button ... Now For Sy-ucomm of that button... provide popup window with FROM and TO parameters...
Then using Loop... Endloop... select that much records form internal table to another internal table say itab2...
Now using GUI_DOWNLOAD or WS_DOWNLOAD or any other FMs and pass the internal table to this FM...
For more information on LOOP Syntax...
LOOP AT itab - cond
Syntax
... [FROM idx1] [TO idx2] [WHERE log_exp].
Extras:
1. ... FROM idx1
2. ... TO idx2
3. ... WHERE log_exp
Effect
The table rows to be read in a LOOP-loop can be limited by optional conditions; if no conditions are specified , all rows of the table are read.
Addition 1
... FROM idx1
Effect
The specification FROM is only possible with standard tables and sorted tables. This specification only accepts table rows starting from table index idx1. For idx1, a data object of the type i is expected. If the value of idx1 is smaller or equal to 0, then it will be set to 1. If the value is larger than the number of table rows, the loop is not passed through.
Addition 2
... TO idx2
Effect
The specification TO is only possible with standard tables and sorted tables. The specification only accepts table rows after table index idx2. For idx2, a data object of the type i is expected. If the value of idx2 is smaller or equal to 0, then the loop will not be passed. If the value is larger than the number of table rows, then the value will be set to the number of rows. If idx2 is smaller than idx1, then the loop is not passed as well.
Addition 3
... WHERE log_exp
Effect
WHERE can be specified with all table-types. After WHERE, you can specify any logical expression log_exp in which the first operand of any singular comparison is a component of the internal table. For this reason, all logical expressions are possible except for IS ASSIGNED, IS REQUESTED and IS SUPPLIED. Dynamic specification of a component through bracketed character-type data objects is not possible. Loops at sorted tables must have compatible operands of the logical expression. All rows are read for which the logical expression is true.
Notes
The logical expression specified after WHERE is analyzed once at entry into the loop. Possible changes of the second operand during loop processing are not taken into account.
While with standard tables all rows of the internal table are checked for the logical expression of the WHERE- addition, with sorted tables and hash tables (as of Release 7.0) you can achieve optimized access by checking that at least the beginning part of the table key in sorted tables and the entire table key in hash tables is equal in the logical expression through queries linked with AND. Optimization also takes effect if the logical expression contains other queries linked with AND with arbitrary operators.
Hope it will solve your problem..
Thanks & Regards

Financial Reporting - Scheduling a Batch to Output/Email an Excel File

We're using version 9 and have no good way to systematically schedule a batch report and have the output saved/emailed as an Excel file, only pdf. Is this functionality in version 11? Has anyone developed creative alternatives?
Thanks

You may be able to utilize Excel and SmartView VBA features to achieve the same goal as this. With enhanced security in the newer realeases of Excel automacally sending emails could be a bit tricky, but if you look around on the web you should be able to find something with this ability. I'm not sure that you could use an FR report, but a report utilizing HSGetValue or ad-hoc functionality should function.

Export the sql output to an excel file

Hi,
I would llke to know how can we export an sql query out put from oracle 9i to an excel file using a java code...
Thanks in advance..
Naveen

Naveen,
You can access Microsoft Excel files via JDBC using the "JdbcOdbc" driver that comes with the JDK.
Hence a simple matter of using JDBC to both extract from Oracle and insert into Excel.
You will find many resources on the Internet explaining how to do this.
Please note that I am certain that this is not the only way to achieve this.
Good Luck,
Avi.

Hi Ardian B. Santoso,
1. Develop the Report in Character Mode.
2. Save the O/P to file.
3. And open the file with MS Excel.
I hope this would be helpful for U.
Have a Good Weekend.

Problem while downloading the alv output to excel file.

Hii,
While downloading the alv output to an excel file i am facing a problem. Either the output comes as 1.23456E+11 or the values get cut .
Cant put in txt file as the users require to calculate directy and i have even tried to increase the output length .But both doesnt help.
So what are the other ways to do so.
Edited by: mansi_v27 on Mar 24, 2010 12:35 PM

Hi,
Welcome to SCN!!!.
Please go through the forum rules. This has been discussed many times. You can search in the forum for this.
Infact there is no problem. Just expand that excel cell. You can see the full value. This is standard excel property.
Thanks,

Problem with opening MS Excel files through Portal

Hi All,
I have a user that is complaining about the behaviour of MS Excel files in the Portal. The MS Excel files do not match their behaviour at the windows level. The issue has to do with how MS Excel files never seem to open in a maximized sate when you open them from the portal. The same cannot be said about MS Word files. The behaviour of MS word files is consistent between windows and portal.
Solutions will be REWARDED.
Thanks & Regards,
Krishnen Subramanian.

Hi Hussain,
I hav uploaded the excel file into my KM contentafter that when i try to open it , it does not open as maximized.
Let me explain:
I create a new excel file on my desktop:
I open this file:
I maximize the workbook and save:
I close Excel and then open the file right back up:
I notice that Excel and the workbook open up maximized. I close Excel again.
I now upload the file to the portal:
I then open the file from here:
It is noticed that the Excel is not maximized. We would like for it to behave as it does from the desktop. In other words, if it is saved as maximized, it should open from the portal that way. If it is saved as half way open, it should open that way from the portal.
I have found that MS Word documents behave in the portal as they do on the desktop. I create an MS Word file on my desktop:
There appears to be something portal related that prevents MS Excel files from opening maximized.
Hope you will be abl to solve the message.
Thanks & Regards,
Krishnen Subramanian.
