How do I upload/download a txt file using struts

what do I need on my JSP page and how do I implement this functionality in an action?

both work differently
upload: <html:file tag (i thin) with a FormFile property in your ActionForm
download use a servlet that uses the outputstream from hte response to send the file

How to retrieve IndividualStrings from a txt file using String Tokenizer.

hello can any one help me to retrieve the individual strings from a txt file using string tokenizer or some thing like that.
the data in my txt file looks like this way.
Data1;
abc; cder; efu; frg;
abc1; cder2; efu3; frg4;
Data2
sdfabc; sdfcder; hvhefu; fgfrg;
uhfhabc; gffjcder; yugefu; hhfufrg;
Data3
val1; val2; val3; val4; val5; val6;
val1; val2; val3; val4; val5; val6;
val1; val2; val3; val4; val5; val6;
val1; val2; val3; val4; val5; val6;
i need to read the data as an individual strings and i need to pass those values to diffarent labels,the dat in Data3 i have to read those values and add to an table datamodel as 6 columns and rows depends on the data.
i try to retrieve data using buffered reader and inputstream reader,but only the way i am retrieving data as an big string of entire line ,i tried with stringtokenizer but some how i was failed to retrive the data in a way i want,any help would be appreciated.
Regards,

Hmmm... looks like the file format isn't even very consistent... why the semicolon after Data1 but not after Data2 or Data3??
Your algorithm is reading character-by-character, and most of the time it's easier to let a StringTokenizer or StreamTokenizer do the work of lexical analysis and let you focus on the parsing.
I am also going to assume your format is very rigid. E.g. section Data1 will ALWAYS come before section Data2, which will come before section Data3, etc... and you might even make the assumption there can never be a Data4, 5, 6, etc... (this is why its nice to have some exact specification, like a grammar, so you know exactly what is and is not allowed.) I will also assume that the section names will always be the same, namely "DataX" where X is a decimal digit.
I tend to like to use StreamTokenizer for this sort of thing, but the additional power and flexibility it gives comes at the price of a steeper learning curve (and it's a little buggy too). So I will ignore this class and focus on StringTokenizer.
I would suggest something like this general framework:
//make a BufferedReader up here...
do
String line = myBufferedReader.readLine();
if (line!=null && line.trim().length()>0)
line = line.trim();
//do some processing on the line
while (line!=null);So what processing to do inside the if statement?
Well, you can recognize the DataX lines easily enough - just do something like a line.startsWith("Data") and check that the last char is a digit... you can even ignore the digit if you know the sections come in a certain order (simplifying assumptions can simplify the code).
Once you figure out which section you're in, you can parse the succeeding lines appropriately. You might instantiate a StringTokenizer, i.e. StringTokenizer strtok = new StringTokenizer(line, ";, "); and then read out the tokens into some Collection, based on the section #. E.g.
strtok = new StringTokenizer(line, ";, ");
if (sectionNo==0)
//read the tokens into the Labels1 collection
else if (sectionNo==1)
//read the tokens into the Labels2 collection
else //sectionNo must be 2
//create a new line in your table model and populate it with the token values...
}I don't think the delimiters are necessary if you are using end-of-line's as delimiters (which is implicit in the fact that you are reading the text out line-by-line). So the original file format you listed looks fine (except you might want to get rid of that rogue semicolon).
Good luck.

Best way to upload and store image file using struts

Hello there,
I'm having two choices for uploading image files(not huge image files) using struts a) to store the image in application server's directory
b) to store the image files as BLOB in database.
Although each of the image files have to be associated with unique ID to identify the image for re-display.
Which is the best option. application server's directory or database
josh

I think storing it in the application server directory would probably allow for faster access, is easier to code, and doesn't depend on db connectivity.
As for the unique id, you could probably use the File.createTemporaryFile method--it returns a unique id for every file in a directory, given a prefix & suffix. You just have to remember to change the extension from a .tmp to the image format you're using.
Anyway, that's my 2 cents.

Upload/Download speed of files using Java

Hey All,
I have created a signed Java applet which, among various other things, allows uploading and downloading of files between the server and client. Both Upload and Download is handled through HTTP. For Upload I create a multi-part POST request to transfer the data to a script on the server which intercepts it. For download I craft a URL to http://myserver.com/filedirectory/file.extension. From that I form a HttpURLConnection and read from the stream to the file system of the client. This applet is only run on an internal network, which currently has 100mbit connection. However, I am noticing upload/download speeds of less than 1MB/s (I believe 100mbit = 12MB/s approx). I am currently using a buffer size of 8kb.
Can anyone think of any ways to increase download speed? Would it help to increase the buffer size, knowing we will always be on a closed network? Here Is my upload code, and my download is similar but in the opposite direction.
int bytesRead = 0;
byte b[] = new byte[BUFFER_SIZE];
BufferedInputStream bufin = new BufferedInputStream(new FileInputStream(f));
while ((bytesRead = bufin.read(b)) != -1) {
        * write output
     out.write(b, 0, bytesRead);
     out.flush();
out.close();
bufin.close();I have not included the rest of the code which creates the POST request because the upload is otherwise working perfectly despite the speed, and I have confined the bottleneck to this part using debug output.
Thanks much

Will removing the flush after every loop somehow decrease accuracy?No.
Ideally, files should be the same exact size on the server as the client after upload has finished.Deferring the flush() can't change that. It just lets you write in larger chunks, which is always good.
Which one is the socket receive buffer?The buffer whose size is set by Socket.setReceiveBufferSize().
Currently the size of BUFFER_SIZE in the example above is set to 8k.That's the application buffer. Good size.

How do I upload and attach the file to Service Request

On Demand doesn't support adding attachments via web services. One
solution I've seen is depending on the scenario is to create a web link
field on an object that's based on a custom text field. Your web service
can populate that custom field and the web link can generate a dynamic
link to the file in On Demand's UI. However, this depends on where the
attachment is located and if the user needs some sort of firewall access.
Hope this helps

How do i search for a string in a txt file using java??

How do i search for a string in a txt file using java??
could you please help thanks
J

Regular expressinos work just fine, especially when
searching for patterns. But they seem to be impying
it's a specific group of characters they're looking
for, and indexOf() is much faster than a regex.If he's reading from a file, the I/O time will likely swamp any performance hit that regex introduces. I think contains() (or indexOf() if he's not on 5.0 yet) is preferable to regex just because it's simpler. (And in the case of contains(), the name makes for a very clear, direct mapping between your intent and the code that realizes it.)

Yes, you could try using the multipart handler...
But I have a better idea...
Determine the maximum number of file uploads that the
user can do at one time. I mean, you can't
realistically have the user upload a million files at
one time. So say the max is 20. So you create your
action form class with 20 FormFile fields called file1
to file20.
Then when you dynamically create your page, you
dynamically create the specified number of file fields
and 1 hidden field called "totalFiles" which contains
the number of file fields you created. This should be
an int field in the form bean.
Then when you do your action processing, you just loop
thru the totalFiles... Or well, actually, you may not
need that at all. You could just check all the
FormFile fields and whatever ones aren't null contain
files.But what about UploadActionForm.java[b]
How do i have exact mapping of the HTML form in this file ??
