Help: writing large data to excel using java

Hi All
I had a question writing a 6000 rows of data with 20 colums to a excel sheet. I am using Apache POI
When we are writing some data to a file we store the data in an stringbuffer and then write the data to the file all at once.
Is the same possible with excel? if so how?
And what is the best way of wring data to an EXCEL file considering the above data into consideration.
Please guide me thanks in advance.
Regards
Diana

Text Files and Excel formatted files treat things differently--basically no, you cannot group multiple fields into one string: Excel has the concept of cells that you need to write the data into and will act similar to fields in a DB. On the other hand, you can drop the Excel formatting and write CSV files and Excel will load them just fine. With a CSV file you can write it all to a String, StringBuffer, StringBuilder or what ever String type of object you want and write an entire line at a time.

Problem with writing continuous data to excel using using Report Generation vi's

Hey Everyone,
I am trying to read the data from DAQ and write to excel continuously using Report Generation vi's.
But when I run the VI, it writes only one interation of the while loop (gathering data from DAQ continuously) and doesn't append the data into the same file when I run it again after stoping the VI.
I have attached the VI i created. Please let me know if you have any idea to solve this issue.
Thanks

There are two problems with your VI. First, the basic logic of writing/appending to a file (Excel, TDMS, anything) should go something like this: Open the file, position yourself at the end of the file, then, in the loop, acquire data and write it to the file until you are finished with data acquisition. When you exit the acquire/write to file loop, then close the file. In particular, the opening and the closing of the file should not be inside the loop.
As others have pointed out, writing to Excel might not be optimal, particularly if you are acquiring data at a high rate (and would therefore be writing a lot of data). We actually use Excel in our data acquisition routine, mainly reading from a WorkSheet to get the parameters of a particular stimulus, but also writing the outcome of the response to the stimulus. As it happens, our "acquisition rate" in this example is on the order of several samples per minute, so there's no problem using Excel (we also sample 16 channels of analog data at 1 KHz -- this gets written as a binary file).
Second, if you really do want to use Excel, use the (existing) Excel file to which you want to append as the "template" argument of the New Report function. Then use the Excel Get Last Row function to position yourself at "end of file", as noted above.
Good Luck.

Problem with uploading data from excel using BDC for tcode f-02

Hi All,
I am uploading data from excel using BDC for tcode f-02. The problem here is, while recording, the values of some fields are recording twice. I dont know why it's happening so. But if I run my abap program, I have to give those fields twice in my excel sheet. Otherwise data does not upload. But it is not the feasible way. We must give those fields once in excel. Please tell me, how I can solve the issue.
With regards,
Rosaline.

Hi,
in BDC each and every action is recording. If your press enter in same screen that also recorded once aging may be this is your case repeating field values will appear. we can solve the problem for repeat fields like below.
suppose in your excel having repeated field X1 X2 X3 the X2 contains repeated field X3 means delete the X3 field.
Now In your itab having X1 and X2 fields. While in the LOOP the ITAB pass the X2 field to repeated the fields.
LOOP at ITAB to WA.
CLEAR bdcdata_wa.
bdcdata_wa-fnam = 'BDC_CURSOR'.
bdcdata_wa-fval = 'RM08M-EBELN'.
APPEND bdcdata_wa TO bdcdata_tab.
CLEAR bdcdata_wa.
bdcdata_wa-fnam = 'INVFO-BLDAT'.
bdcdata_wa-fval = wa-X2." 1st time pass the X2 fields
APPEND bdcdata_wa TO bdcdata_tab.
CLEAR bdcdata_wa.
bdcdata_wa-fnam = 'INVFO-BLDAT'.
bdcdata_wa-fval = wa-X2." pass the same value to repeated field
APPEND bdcdata_wa TO bdcdata_tab.
Endloop.
Hope you can understand.

Import data from Excel using SDK!
Thnx in advance

Hi Vinayak
4 your 2nd issue: you can easily use Excel.Application COM-object. In C# exporting from Excel can be:
Excel.Application     oXL;
Excel._Workbook     oWB;
Excel._Worksheet     oSheet;
string          strTemplatePath;
strTemplatePath = Application.StartupPath + "WHRequestList.xlt";
try
     oXL = new Excel.Application();
     oWB     = (Excel._Workbook)(oXL.Workbooks.Add(strTemplatePath));
     oSheet     = (Excel._Worksheet)oWB.ActiveSheet;
     SAPbouiCOM.Item     edDocNum;
     SAPbouiCOM.IEditText specEdDocNum;
     edDocNum = SBOApp.Forms.Item(FormUID).Items.Item("8");
     specEdDocNum = (SAPbouiCOM.IEditText)edDocNum.Specific;
     SAPbouiCOM.Item     edDocDate;
     SAPbouiCOM.IEditText specEdDocDate;
     edDocDate = SBOApp.Forms.Item(FormUID).Items.Item("10");
     specEdDocDate = (SAPbouiCOM.IEditText)edDocDate.Specific;
     oSheet.Cells[2, "F"] = "¹ " + specEdDocNum.String + " îò " + specEdDocDate.String;
     oXL.Visible = true;
     oXL.UserControl = true;
BTW, don't forget to add Excel object in ProjectReferences
For sure, importing (reading) from Excel is the same

Update file date/time stamp using java

Let me explain you what I am going through:-
I have created a java based installer using Jexpress tool and after I do the installation of my files, the files takes the current date rather then taking the date when it was created or modified.
Everything goes into JAR and I heard that Jar file do not retain the date/time stamp of the file.
I would like to know if we can change the date and time stamp of the files using Java.
Is there any method to do that or can we do this by writing the java class?
Thank You
Mehul

Export data to Excel + use of xsd

Hi,
I'd like to export data from oracle to excel using pl/sql. These files go to subcontractors who will have to make some kind of customization to that data. I want to prevent these subcontractors from writing trash to this excelfile (writing text to a numbercolumn). As far as I know, this can be done using xml schema (supported since excel 2003).
Is it possible to generate an excelfile using pl/sql and also include an xml-schema according to the columntype defined inside the database?
Oracle Version is 11GR1
Thanks

Thanks for your reply.
As far as my understanding of xml and xsd is correct: XML is used to transfer data to an excel-sheet. This is the data from a table/query or something like that.
The XML Schema defines the structure of this data. Lets say you have the following table:
create table test(
x number
,y varchar2(20)
Exporting the content of this table might result in the following excel-sheet
x | y
|20 | test |
|30 | test |
Because this excelfile is sent to a subcontractor, I can't control the data he inserts into x or y. He might insert
x | y
|20 | test |
|30 | test |
|test | 40 |
When trying to import this table, there would be errors. Now I'll call the subcontractor telling him that he's not allowed to insert text into x. To avoid this situation, I'd like to use XML Schema. If there is another way to prevent this situation from happening, pls tell me.

Need help with tomcat 5.5 and using java classes

hey there,
i am trying to set up tomcat 5.5 on my computer at home and have sucessfully done so. i have been trying to use Java classes inside my JSP files however tomcat thows an internal servlet error as follows:
org.apache.jasper.JasperException: Unable to compile class for JSP
An error occurred at line: 144 in the jsp file: /order.jsp
Generated servlet error:
ProductList cannot be resolved to a type
An error occurred at line: 144 in the jsp file: /order.jsp
Generated servlet error:
ProductList cannot be resolved to a type
An error occurred at line: 144 in the jsp file: /order.jsp
Generated servlet error:
Product cannot be resolved to a type
i have the classes located as the setup tutorial recommends (root/WEB-INF/classes/) and still nothing works. i would appreciate any help anyone can give.
thanks,

Which tutorial are you following?
As of java1.4, all classes must be in packages for them to work in Tomcat. This means your beans and servlets too.
Put your beans in a package, and then recompile them, and put them in the right place.
eg
package com.mypackage
public class MyClass ...
once compiled would go into WEB-INF/classes/com/mypackage/MyClass.class
Are you using Product and ProductList classes in scriptlet code?
Have you imported them with a page directive
<%@ page import="com.mypackage.Product, com.mypackage.ProductList" %> ?
