Hi
I would like to upload a file from a html form, and use java code in my
jsp file to download it to a new location.
I have the html for file uploading all set up, and I know how to set up
an inputstream in java, but I do not know how to connect the two i.e.
connect the file accessed by the upload form to FileInputStream in my
jsp file.
The form looks like this:
<form method="GET" action="p_enter.jsp">
<INPUT TYPE=FILE NAME=documents SIZE=40>
<INPUT TYPE=SUBMIT VALUE=Submit>
</form>
But where the form is processed, in p_enter.jsp, how do I get the data
from the file in FileInputStream?
I know about:
try {
BufferedReader inputFile=new BufferedReader(new
inputStreamReader(new FileInputStream(?)));
Then I can do something, like write the data out to an outfile
}catch(IOException ex1){return;}
The above java code works well directly from a local disk - but I am not
sure how to do this from a upload link on the web.
When I upload the file, I would like to specify the path on the server
where I want to download the file, check if a file with such a name
already exists, and if so, insert a number before the file extension eg.
myfile.doc already exists, so the next myfile.doc automatically becomes
myfile1.doc. Then I would like to save the file, and keep the path and
filename available to write to a MySQL database.
Writing to the MySQL database is all under control, but I can't seem to
find a way to upload the file, check and (if necessary change) the
extension and lastly download the file to a location on the server.
Could someone help me out with this? A code example to get me started
would be very welcome.
Note that I am using apache with tomcat on a linux webserver and would
like to use jsps. I would prefer to write the code myself rather than
making use of pre-existing code. This is because I would like to retain
control over what I am doing.
Thanks very much.
Hugo
