Programming Excel from Java

How can I copy an EXCEL file from a NT machine to a Unix machine and then present it on client's workstation, when the application server is in Unix. Please think of a situation wherein the EXCEL file got created on NT Server, the application server is installed on a Unix, web application is a Servlet running in Unix and the User initiates a request from a browser.
can someone please help. this is urgent for us.

Can you please help by elaborating a little further?Yes - but SEARCH THE FORUMS, similar questions:
"how do I send an image the browser"
"how do I send a pdf the browser"
"how do I send a word/doc the browser"
set the mime type appropriately in the http response
write your byte stream to the http response output stream

If you are using POI, you can set the background colour for a single cell.

Reading Excel from Java

Hello,
I would want to read excel data from Java. I do not want to register any excel drivers as I will not be able to know the file to be read before hand. Are there any better ways to solve this ?
Thanks in Advance,
Prasanna

hi prasanna
if you are using jdbc-odbc bridge I would recommend you to test the
program with excel files with varying sizes like 3,5, 12, 20 etc. There
is a some problem with the driver that it chops off some data.
For example if you have 20k excel file the driver may read in 9k chunks so you get 18k of data read and the driver ignores rest 2k.
Make sure of that it works on all sizes of input data.

Accessing excel from java code

Hello
our system uses reportNet to generate reports. When reports are generated in CSV format we have a problem:
Report consists of people (can be more than one) so under name column we have same name in more than one row. BUT if more than one name is suppose to be in the CSV report then the header (column names row) is again printed.
so for example if i requested rpeort for two names A and B (reportNet uses same template which is executed twice) then report will look like this
Name (header - column name)
A
A
A
A
A
Name (header - column name)
B
B
B
B
I want to be able to remove the second header that comes before B starts.
so i was thinking i would be able to access this excel sheet from java. and keep record of every row. If the row changes from A to B...i delete the previous row (which would end up being the second header).
Can this be done thru java. I havnt before accessed excel sheets from java so any pointers would be greatly appreciated.

Hi, well CSV is not currently an Excel file, it is a Comma Separated Values
file which can be read through Excel.
Now, if you wish to remove the header, I would purpose that you develop an
application that reads the CSV file, as it is mere text, and that it also reads
another file (lets call it confirguration.txt) in which you determine the pattern
you want to remove, then you just read your report and if a string line
matches the pattern you defined in the configuration.txt file, then you simply
erase it.
And if you keep interested in reading real Excel files (xls), I would
recommend you use POI-HSSF API from Apache.org
http://jakarta.apache.org/poi/hssf/index.html
Hope this helps, cya around.

Excel from JAVA or C++ -- Urgent -- help

Hi
I know it might not be possible, but i want to use couple of Financial Functions which excel provides within itself.
Is there anyway i can use them from my JAVA or C++ code ?
In short, would it be possible to call excel functions from JAVA or C++ code
TIA
Vikram

Actually you can... In quite a few different ways. You can access any COM or OLE object in windows from within java by using the Java/COm bridge, or purchasing shrink wrapped products... The links are below:
These people provide some very cool solutions for java. This link is specifically for excel.

Using word/excel from java (client or weblogic server)

Hi everybody,
i want to use excel / word functionality from java in two different variants:
-> serverside
-> clientside
I tried the weblogic.comc and i got serveral classes but in the remote-package i got only a utitlity-class.
My knowlege about COM is rather bad.
Does anybody did this bevor and
-> can say me, if it is correct, that i only got a utility-class (so how will i use it from the client ?!)
-> has a example for using Excel / Word from Java in bea weblogic
-> has a example for using Excel / Word directly in a client (not via rmi)
Thanks
Ciao

There is a danger of deadlock in this code. The OP should read the 4 sections of [http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html|http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html] and implement ALL the recommendations.

Invoking MS Excel from Java

HI,
I'm trying to create a standalone application that would need to logon in a database.If the user is a valid one, the user can then choose which table he wanted to update. All the rows of the column will be shown in an excel format. (the program will invoke Excel to show all the records in that table). From that, the user can edit the content and after saving it, data in the databse will also be updated.
Is there any Java API that I can use to make this application possible?
Thanks,

Can programs run from java that is on web browser

i have written a program and used autorun to run when a cd is put on but not every body will have java on their computer a firend told me that most people will have java on the web browser that will be able to run the cd is this true or will i have to give download instructions to download jav first. this is obviously not ideal as i want people to be able to run the program by putting the cd in and nothing else.

1. You can create a Java applet, which is a Java program that runs
from a web page. It will need to be a signed applet. Your autorun will start the browser with the web page carrying the Java applet.
I don't think this is optimal.
2. Search for "embed JRE", which describes how you can supply your
private JRE with your program. It does not install the JRE, nor does it
care if one is already installed. I did this many times, there is no problem
at all, but here I have no idea whatsoever what happens if your JRE originates from write protected media. I guess it should work. Experiment or wait for others to see what they think.
