How to open and store a data to excel file usig java

you hava a data in database .you can reterive the data and tranformed to excel file.you can save as well as poen it possible or not?

Here is your basic issue: setting a classpath (and presumably compiling and executing a program) is one of the most basic, fundamental concepts in Java. I would advise you to follow JVerd and Annie's links and get started on a tutorial. Try writing a simple HelloWorld application before delving into POI. When you are more comfortable writing and compiling programs, and post a specific question, it will be much easier to help you.

How to export the text edit data to excel file without splitting the data in excel file?

how to export the text edit data to excel file without splitting the data in excel file?
I have a requirement in SAP HR where in the appraiser can add comments in the area given and can export that to excel file. Currently the file is getting exported but the comments getting split into deifferent rows.
I want the entire comment to be fit in one row.
Please help.
Thank you

Hi,
if your text edit value is stored in 'lv_string' variable.
then before exporting the value to excel you have to remove CL_ABAP_CHAR_UTILITIES=>NEWLINE
that is '#' from the variable lv_string.
for that use code some thing like this.
REPLACE ALL OCCURRENCES OF CL_ABAP_CHAR_UTILITIES=>NEWLINE in lv_string WITH space.
I think this will do the trick.

What is the best way to read and manipulate large data in excel files and show them in Sharepoint

Hi ,
I have a large excel file that has 700,000 records in it. The excel file has a few columns that change every day.
What is the best way to read the data form the excel file in fastest and most efficient way.
2 nd Problem,
I have one excel file that has many rows each row contain some data that has certain keywords.
What I want is to segregate the data of rows into respective sheets(tabs ) in the workbook.
for example in rows have following data
1. Alfa
2beta
3 gama
4beta
5gama
6gama
7alfa
in excel
I want there to be 3 tabs now with each of the key words alfa beta and gamma.

Hi,
I don't really see any better options for SharePoint. SharePoint use other production called 'Office Web App' to allow users to view/edit Microsoft Office documents (word, excel etc.). But the web version of excel doesn't support that much records as well
as there's size limitations (probably the default max size is 10MB).
Regarding second problem, I think you need some custom solutions (like a SharePoint timer job/webpart ) to read and present data.
However, if you can reduce the excel file records to something near 16k (which is supported rows in web version of excel) then you can use SharePoint Excel service to refresh data automatically in the excel file in SharePoint from some external sources.

How to open and read many files from a directory and store contents in 2D array?

I want to make a VI that opens and reads the data from various files contained in a directory (200 files each with 2 columns) and store these in a single 2D array. For file number 1 I want to store the data from both columns in the 2D array, but for files 2 to 200 I only want to store the second column of each file. Can someone please help?

Hi Nadav,
Thanks for your help. I have followed your instructions but i cannot get it to work. I used the LIST DIRECTORY to list the files in the directory - that works. However, how do I read each of the 200 files using READ FROM SPREADSHEET FILE without me having to manually select each of the 200 files? So, if I use LIST DIRECTORY to list all 200 files in an array, how do I get each of these to open and store the data in a 2D array? Here is what I have done (File called read_files.VI) Could you please help me? Thank you very much in advance.

Opening and saving from web site pdf file

I found a site where you can download many pdf file. In order to automatize the process i would create a vi using activex.
i generate some url like this "http://remotesite/folder/file1.pdf" and i want the vi open the site, download the page an save the file1.pdf in a desired folder. In this forum there are many examples that solve only half of my problem, in fact they load in a browser the pdf file opening Acrobat reader but i do not know how to save the file.
Thank you
lelluzo

Why do you want to do this with ActiveX?
Try the WinInet: http://www.mooregoodideas.com/goodLabViewStuff.htm
Simply use WinInet Easy Get Url, with a path to the file, and store the data as binary file. I used this a lot for the axact thing to are trying to do. Put the VI in a for loop, and try to automatically build a string that forms the paths to the files. Sometimes, I get the source HTML from a download page, and edit the HTML so I get a multiline string. This forms the input for the loop, and there you go. All your files nicelly on disk. Note that some of these sites will block after a few downloads, to prevent this sort of things.

1) Next time use the CODE tags. this is way too much unreadable crap.
2) The problem is your String[][] data.... the only place I see you do anything approching initializing it is
data = new String[numLines][];I think you want to do this..
data = new String[numLines][3];anyway that's why it's blowing up on the line
data[row][col]=st.nextToken();

How to open and close posting period for both material , n invoicing

HI
how to open and close posting period for both material , n invoicing , AM NEW TO SD , SO ALL DOUBTS I DO POST IN HERE PLEASE DONT MIND

Hi Sunaina
Period Open T.code: MMP1
Period Close T-Code: MMPV
Automate the opening of MM periods
How can you automate the monthly opening of MM periods (transaction MMPV - program RMMMPERI) with
SM36?
RMMMPERI accepts a period/year or a date.
If you enter a date the period is derived by it.
1. create a variant and check the attribute 'selection variable' for the parameter date. Then click the button 'Selection variables' and set the current date. Every time this variant is used the parameter DATE is filled with the current date.
2. create a job for RMMMPERI with the variant created in the preceding step. Set it as periodic.
If you're not using a fiscal year variant simply schedule it as monthly (to be executed the first day of the month).
If you are using a fiscal year variant you'd have to define a calendar with only the first day of each period defined as working
day and use it in the periodicity restrictions.
Another possibility:
Write a very simple ABAP which run daily to check if the period has changed and submit RMMMPERI.

How to open and navigate between human task forms in a same page?

Hi
I use Oracle BPM 11.1.1.5
I have a question about taskflows in BPM Application.
In ADF web application, I create a sipmle task flow and insert view id and bind these to jspx pages, my pages are opend in same page when
return an outcome.
For exapmle I have three pages like A,B,C.
In task flow, insert three view ids and bind to A,B,C.
My first pages is A, and when outcome is B navigate to B, when my outcome is C then navigate to C in a same page not separate pages.
But my problem is here.. in BPM Application when create task forms, every task has a separate task flow that there exist a single view id and a wild card flow in it.
In BPM workspace when initiate human task form is closed, I should press refresh button to see next human task form in task list table.
I tried to create a simple task flow and insert human task forms in it and navigate between these.. but show human task form in wrong display and don`t show some component and human task payload.
Now, my question : How to open and navigate between human task forms in a same page like software installation?

Having a separate Data Control for each human task is normally the case. There is a way to assign multiple human tasks to a single data control (and one task flow), but I don't think that this is going to help you with what I think you're trying to do.
If your human task is called "EmployeeDetail", then you'd use the data control associated with this for the UI pages in the task flow diagram that is associated with this human task. For example, you might have a first page that has just the basic employee information - the fields (at least the ID field) would come from the EmployeeDetail data control. When the end user clicks "Next", you might have this UI page flow to a second UI page in the task flow diagram that has the employee's address information. You might place the address fields from the EmployeeDetail data control onto this second UI page.
You might be asking how the work item instance can automatically flow to the next interactive activity in the process while staying inside the first interactive activity's human task's task flow diagram. This is not how it works - the task flow diagram models the end user interaction while inside a single human task that is tied to a specific interactive activity in the process. If you want a the end user to be able to move the instance through multiple interactive activities in the process in one interaction, look at "Activity Guides". Activity Guides do a nice job of this.
