Garbage characters in excel file opened by jsp

          I am storing an excel file as blob in database. While retrieving
          from database when I open in the jsp page , it shows a lot of garbage characters
          and all formatting is lost. I am using content type "application/vnd.ms-excel".
          I am also setting correct mime type in web.xml as application/excel. It is weblogic
          6.1 sp2 with oracle 8.1.6. the pdf and word docs are working well. Please help
          soon.
          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.

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

LIST_FROM_MEMORY - Excel File - Open data set

Hello,
A long time ago I asked people here how to convert a submit program to html and using open/transfer/close data set altoghter. I got a lot of help for that and I am greatful.
However, I may need to try something and would like to ask how does this apply when you want to transfer <b>LIST_FROM_MEMORY -> Excel File -> Open/transfer/close data set</b>leading it to be saved to the application server.
Thank you all and good day.

Do we have to write the list into application server in XL format?
Once we get the data from LIST_FROM_MEMORY, then write this data into application server using DATASETS
Refer to these links

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.

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

Can I globally change a setting so that Word/Excel files open in NeoOffice

We are evaluating the use of open "Office" applications. Is there a global setting that will allow us to force Word & Excel files to open in NeoOffice (and vice versa)? In addition, is there an Import Data feature in NeoOffice or OpenOffice?

Downloaded excel files opened in multiple instances

Whenever I download then open the file from Firefox, it opens in a new Excel instance. Hence I am not able to move data to other workbook I had opened previously, and have to save it first, then reopen within the same instance. How do I force it to open in the same instance?
I didn't have this problem before with Firefox, it worked just how I wanted. But suddenly something changed around 1 month ago (unknownly) and I have to go through extra step to save then reopen every time. I have searched the web for similar problem but none helped.
I don't have this problem with Excel itself. (when double click on the files it always open in the same instance) Also, the same problem doesn't exist on my other computer (With the website/Firefox), so I'm just puzzled which part caused the problem. I've tried to reinstall Firefox, restore everything to default. But problem still existed. I don't recall changing any setting when this problem started to occur. Any help is appreciated!!!!

I know going through the route "open file" in EXCEL can assure me files are open within the same instance, but I want to eliminate this extra step. As mentioned, previously, this can be done without any problem. I'm just repeating the same step as done before, but suddenly, all these new downloaded files stopped open in the same instance, and I don't know which setting is off and caused this.

File opening from jsp

Hello,
I have a file in the server's hard disk.
A I have jsp with the link to the file.
I'd like to file be opend with the standard windows application after clicking on the link.
How could I realize this? What kind of file link I need?
Thanks,
Ljosika

You must put link to some "context" of your web server not to server hard disk.
eg. if you're using Tomcat you can create directory "downloads" under "ROOT" directory in webapps directory and then you can put files there and use.
DOwnload file
If your application is under Tomcat/webapps/myapp then use
DOwnload file
and so on...

Opening an excel file in jsp

how do you open an excel file in my jsp and target it to a table?

can't it be done using the file class?
i just want to open the excel file, that's all--
Open means what ?
See if this is useful
String myDB = "jdbc:odbc:Driver={Microsoft Excel Driver (*.xls)};DBQ=c:/book.xls;"
+ "DriverID=22;READONLY=false";
//con=DriverManager.getConnection("jdbc:odbc:myExcel");
con=DriverManager.getConnection(myDB,"","");
dbmd=con.getMetaData();
stat=con.createStatement();
rs=stat.executeQuery("Select * from `Sheet1$`");//[Sheet1$]--
I think it is not possible with File class. and if it is so
then how you are going to handle the data ?

How to download Excel file in JSP Page

Actually I have a page
Where I am uploading the files to server and it is listing the files which are all uploaded to the server.
If I try to click the file which is uploaded it has to download to the local system.
DOC, TXT, PDF, PPT. These file formats are try to download to local. But Excel file, opening the file content only not downloading to local.
Any solution

Hi Bangalore:
As my experience,there may be some symbol such as "\r\n" was added in the content of the Excel file you want to download. this is no porblems to text format file, but to binary format file, such file can not be open. So I suggest you check-up the content of the file befor it was writed to the client, remove unwanted symbol, it should be word!
I'm a newer to the here , and my english is poor. I thirst for intercommunion, I'm sorry for the syntax error in my reply.
