How To Store Files On a Server?

I am using the Tomcat 5.0.27 web container. I have always store things into the database. Now, I am told to store files (uploaded files) on the server. And, when clients want the files later on, clients can download them.
Because I have not yet had this concept, I need help and explanation.
1. How to store files on a server?
2. Where on the server that files can be stored?
3. How to let clients download files when they are asked to be viewed?

Look at the Jakarta Commons FileUpload package.

How to store file in Application server.

Hi all,
I have done a report where using excel sheet data i hv to insert in ztable. I have done it i hav converted excel sheet data into internal table and then inserted into ztable. It is working properly. using p_file like rlgraph-filename i have taken the parameter and function module filename_f4 uploaed file.
Now i when i am runing the report it is inserting properly in foreground. But i have requirement that i have to run the report in background but it is giving error in background. So what i do is the excel sheet which i take as input should be stored in Application server and then i have to pick up the file from application server during the background process. So any body can tell me how to write the program to store file in application server and pickup that file again to run it in background.

How best store files on application server: Tables vs File system

Hi Experts,
We want to let users to upload files to application server. The number of files can potencially grow over time (1000 files every month) though I whould like to limit size of each file not more than 1-2 MB.
Also files should be classified (having custom attributes) so later on we need to search, select files according to attributes.
So what are the best options in long run (for performance, reliability etc)?
We have NW system 7.0 with MaxDB
I can think of the following options:
1. Store files in TRANSPARENT table in RAWSTRING. Easiest variant (to select files etc) Here I have concerns how this table and database behave after some period of time and what will happen if size will grow to let say 50 GB. Will it work? What are normal size limits for transparent tables?
2. Store files in CLUSTER table in RAWSTRING. Less convenient to work with (joins are not allowed etc). Will cluster table help to handle big size of table? What are practical size limits for cluster tables?
3. Store files on file system (on application server) and write info (attributes etc) into ztable. Select from ztable and read content file from file system (dataset commands?). So files will be written to one directory just one after another.
What are the best option to follow? I would personally prefer option 1 as easiest but have servious concerns regarding size of one transparent table.
What do you recommend?
Regards,
Dmitry.
Edited by: Dmitry Kalmykov on Jul 28, 2009 8:58 AM

Hi,
I too feel that option 1 would be best choice.
For your ref: Check the Transp.table REPOSRC and the field name DATA
Also Check the technical settings (Size category).

How to transfer file from application server to presentation server in background?
Thanks in advance

Thanks Raman and Challa,
We want to move file from application server to Shared folder, not on local machine. We checked FM which you guys have provided but those are not able to read file from application server.
We need this program to run in background so that we can use this in daily process chain.
Appreciate your inputs on this.
Thanks,

Not to mention that some FTP servers can return more than one return message per operation whereas others may return one message for the same operation.I had the problem using the LIST command to determine if a file exists on the server. Cannot be determined via the FTP server's return code. Which means parsing and checking the text response from the server to the command. And this vary from server to server.
But the basics were quite easy to code. The entire package is 500 lines, includes comments and blank lines for formatting, and supports the basic FTP client command set. Not really a complex piece of software to write - but I found that many developers seem to think that writing network socket software is complex. Not really the case...Mine's a big larger, but incorporates functionality similar to what Chris provided in his, such as being able to use SQL to query a remote file using pipelined functions, or functionality to write the results of a query directly to a remove file.

How to store files in shared-folder in background mode

Hello All,
My requirement seems to be simple but I have tried many ways in achieving this, but failed. So require the help in accomplishing this task.
Requirement
I have to create a program in SE38 which will create a internal table with data in it in .XML format(which I can achieve).
My requirement is this .XML file needs to be placed in a shared-folder in "BACKGROUND MODE".
I have tried using GUI_DOWNLOAD function module, but this FM only runs in Foreground mode and fails in Background mode. I have tried convincing my client that I will keep the file in Application Server as it is achievable using OPEN DATASET statements, but they are not willing to accept this.
So can you please help me in achieving this task as I am not getting any solution how to keep the file in Shared-folder in BACKGROUND mode itself(not Foreground).
Best Regards,
Tousif

Do you want to return the file to the user on click of button or something?
Then, use web_show_document with http link which you are speaking about.
Else download the file to client using Webutil.
