Uploading a file from a J2ME application

Ok, obviously this is either not interesting, or no one really knows what to do, I would love any ideas even if they dont work, just anything that would help would be great :)
I am extremely new to servlet programming and reasonably new to J2ME. I want to upload a file from my device to a central server. I am not sure how to go about starting this. I have a html form that requests a file and posts it to the servlet fine, but I am not sure how I would get my J2ME application to do the same. Do I replicate the html from with in the program? Any help would be much appreciated.
My basic servlet and Java code is:
Java
public String sendPostRequest(String urlstring) throws IOException {
              HttpConnection hc = null;
              DataInputStream dis = null;
              DataOutputStream dos = null;
              String message = "";
              // the request body
              FileSystem fs = new FileSystem();
              byte[] file = fs.returnFile("c:/other/dot/helloworld.txt");
              if(file != null){
                   String fileString = ("file=" + new String(file));
                   try {
                     // an HttpConnection with both read and write access
                     hc = (HttpConnection)Connector.open(urlstring, Connector.READ_WRITE);
                     // set the request method to POST
                     hc.setRequestMethod(HttpConnection.POST);
                     // set request type
                     // Could possibly need to be "application/x-www-form-urlencoded"????????????????????????????????
                     hc.setRequestProperty("Content-Type", "multipart/form-data");
                     hc.setRequestProperty("Content-Length", fileString.length()+ "" );
                     // obtain DataOutputStream for sending the request string
                     dos = hc.openDataOutputStream();
                     byte[] requestBody = fileString.getBytes();
                     // send request string to Web server
                     for (int i = 0; i < requestBody.length; i++) {
                       dos.writeByte(requestBody);
               // flush it out
               dos.flush();
               // obtain DataInputStream for receiving server responses
               dis = new DataInputStream(hc.openInputStream());
               // retrieve the responses from Web server
               int ch;
               while ((ch = dis.read()) != -1) {
               message = message + (char) ch;
               } finally {
               // free up i/o streams and http connection
               if (hc != null)hc.close();
               if (dis != null)dis.close();
               if (dos != null)dos.close();

I've only done one small j2me program and not recently, but here is a link that can give you some of the basics: http://today.java.net/pub/a/today/2005/02/09/j2me1.html
I'm guessing, but I believe you have to use http sockets to accomplish a file transfer with a phone. Also, there are some limitations with full sockets depending on which type of phone you using to write your app to.
Hope that helps!

How to upload pdf file from windows cell phone?

How to upload pdf file from windows cell phone?

You can do this in steps.. First use the built in method for uploading a file into the flows files object, Next you would copy the file out to an Oracle built directory on your UNIX box using utl_file.put_raw..
Here is a link to show you how to upload files in an APEX application [http://download.oracle.com/docs/cd/B31036_01/doc/appdev.22/b28839/up_dn_files.htm]
And here is a link to show you how to use utl_file.put_raw.. [http://psoug.org/reference/utl_file.html], item is towards the bottom of the screen..

Upload a file to portal--- BW application server.

Dear All,
I have requirement where some part of business does not have SAP installed. But we would like to extract data from these business too.
So just wanted to know if we can have a scenario where user will upload the data to the portal (this is just a web portal). Can this be done?
Secondly, if the can be done, can we extract the file from portal to application server? From application then it becomes very simple to upload to data targets in BW.
Please help in this regard.
Thanks,
Sandeep

Assign an ID (e.g. 1234) to the uploaded file. You should abstract the store
so that it will work on the file system or in the database.
The JSP will include an image ref to that ID, e.g.
http://www.myco.com/myapp/imageservlet?id=1234
The image servlet will retrieve and stream the image. It has to set content
type etc. You should also verify that the current user has access to the
requested image if security/privacy is an issue.
Peace,

Uploading excel files from ITS to sap

Hi all,
I want to upload excel files from ITS to sap system ECC 6.0 .I am using standalone ITS.Someone please help me find a solution for this.What are the steps involved in it?
Thanks in advance
Shinu

Hi Shinu,
this seems to be a misunderstanding. The ITS does not have excel files.
Did you mean to say that you have an application which allows to upload
files? This application might work using the webgui service of the ITS.
Try it out!

Help please to Upload a file from my PC to server's KM

Hello:
I can't Upload correctly a file from my local PC to a KM of the server.
My problem is after that I've uploaded any file from my PC to KM, sometimes when I open or download it from the KM appears blank, and when I try another way to write the file (out.write()) I've uploaded a bad file that can't be downloaded or opened it. I can't get the file Data of the file for uploading, I need to set it with the fileResource (I tried with fileResource.read(false))
I use a FileUpload in my view.

How to allow the user to upload a file from their desktop to MII Server?

Hi,
Is there a way for the user to specify a file on their local computer to upload to the MII server for processing? We have a method that works for uploading from a shared network drive, but now the need/desire is to allow the user to upload a file from their desktop.
Ideally, this would be a file browser that the user would click on to browse their local desktop and select the file and click "Upload" but not sure what's possible?
This is using 12.1 SP4.
Thanks for the help.

Timecapsule - opening files from within an application!!

I have a time capsule... 500Mb
I have an airport extreme with external hard drive - 250 Mb.
Through Finder, I can place files on either of these drives and open them from Finder.
If I open Numbers, or Pages, then try to open any file on Timecapsule, it appears that there are no files
If I open Number, or Pages, then try to open any file on the Airport Extreme external disk - it works!
Simple question really.... why cannot I see or open any file from within an application that resides on Timecapsule?? It's driving me crazy!!!

File dialogs have the ability to "group" items, which prohibits you from changing sort options. The group icon looks like six little squares. Click on it and instead of grouping by date, group by "none" and then you can change sort orders.

But i need path and have to do some calculations on it.No, you don't. If you have requirements which say you do then the requirements are wrong. You couldn't do anything useful with the path on the client system even if you could get it.
is there any alternatives in java
I need path and have to calculate MD5, Presumably you need to calculate MD5 on the contents of the file and not on the name of the file.
and convert the file to binary format.... etc oprations on itSorry, "convert a file to binary format" is basically meaningless.
but we can get the content of the file using
byte [] get()/ getString() methods
If i get content is there any performance degrades?
ie if the content is lengthy is it take more time?Take more time than what? Degrading performance from what? It's certainly true that it would be quicker to not upload the file, but that's a pointless comparison. If you have some other process to compare with, let us know what it would be.
