How to upload an html file using jsp and jdbc

Hi,
im trying to upload an html page using JSP and jdbc. but of no success.
my aim is to keep some important html pages in the database.the file size can vary.the file has to be selected from a local machine (through the browser) and uploaded to a remote machine(where the databse resides).
any help/sample code or pointer to any helpful link is appreciated.
thanks in advance

When uploading a file, I use a byte array as a temporary buffer..
So, you should then be able to store the byte array in the
database as binary data.
example>
//Temporary Buffer To Store File
byte[] tmpbuffer = new byte[860];
//Some Code To Upload File...
//File Should Now Be In Byte Array
//Get DB Connection and execute Prepared Statement
Connection con=//GET DB CONNECTION;
String sql=insert into TABLE(page) values(?);
PreparedStatement ps=con.prepareStatement(sql);
ps.setBytes(1,tempbuffer);
ps.executeUpdate();
//Close PS and Free DB Connection
..... and this method looks like you dont even have
to store the file in a byte array, you can just give
it the input stream.
ps.setBinaryStream(int, inputStream, int);
You may have to make several attempts at this. I have
uploaded a file and temporarily stored it in a byte array,
but have never from there stored it in the DB as binary
data.. but this looks like it'll work.
Good Luck!

How to upload a graphic file using JSP?

Thanks

The same way you upload any other file. Your form must be declared with multipart/form-data encoding and then, upon the form submit, you will have to parse a multipart request. There are a bunch of libraries around that do that. Our product, TICL (at http://www.kobrix.com) includes a server-side FileUpload component that does it and there a few free, special purpose ones that may help too - do an internet search ;)

How do you reference image files in jsp which becomes a portlet ?

My portlet is a servlet managing jsp pages. In each of the jsp s, there are image files (*.gif) being referenced. I have placed the image files in .../public_html/WEB-INF/images/ in explorer. In my jsp, I am referencing the image file as
src="WEB-INF/images/help.gif"
On deploying my portlet, the image is not being picked up by the portal. Also, on moving the image and modifying the reference to it, I am still getting the same problem.
Can anyone advise, for my portlet to display the image correctly,
1) where should I place the image files ?
2) how should the jsp code reference it ?
Cheers,
Tara

Hi,
The behaviour you are reporting is an expected behaviour. If you want to include images in your JSP, you need to specify the complete absolute URL to the image on the midtier as only then can the portal invoke that image.
Actually, when you specified the relative URL
WEB-INF/images/help.gif, Oracle9iASPortal actually looks for the image help.gif in the directory structure WEB-INF/lib at its end. As no such file exists, the images are not rendered onto Oracle9iASPortal page.
So you got to use the following workaround,
Assuming your provider name is "temp" (deployed using temp.ear) & the image name is "help.gif" which is stored in the htdocs folder inside temp. This image is invoked by help.jsp
You can get the absolute path of this image as follows:
Request URL is : http://<host>:<port>/temp/providers/temp
Request URI is : /temp/providers/temp
So, Base URL = http://<host>:<port>
Servlet Path is : /temp/htdocs/help.jsp
Truncating the Servlet Path to /temp/htdocs & appending this to Base URL should give you
http://<host>:<port>/temp/htdocs
which is the directory that contains your image. add image name to this URL to get the absolute p[i]Long postings are being truncated to ~1 kB at this time.

How to upload an image from servlet/jsp into server from clients machine?

can anybody send me the code to upload image from client to server using servlet/jsp.
i'm using tomcat server.

You can use the [Apache Commons FileUpload API|http://commons.apache.org/fileupload/] to upload files using Java.
Here is a Filter example which uses the FileUpload API to process the request and stores the regular request parameters back in the ParameterMap of the request and puts the uploades files as attributes of the request: [http://balusc.blogspot.com/2007/11/multipartfilter.html] Just define it once in web.xml and you can continue writing the servlet logic as usual.

How to retrieve data (xml file) using jsp

I am a newbie to xml. I have decided to store my information in the xml file. may I know how can I retrieve my information from the xml file?
Thanx in advance.

I am a newbie to xml. I have decided to store my
information in the xml file. may I know how can I
retrieve my information from the xml file?
Thanx in advance.You can get the information from the XML file using one of the parsers available, such as Xerces http://xml.apache.org, and JDOM as an API.
Using this you have the option of having a SAXParser or a DOMParser.
SAX (Simple API for XML) is an event based parser, so if you know the XML structure, and need to find a certain element, you can just look for the element name,and retrieve the value of the element, it's attributes and its children.
DOM(Document Object Model)represents the XML as a tree, but uses more resources as it stores the entire tree in memory. But it is good in that you can traverse the whole tree.
JDOM would be a good idea too. If you download this, you can use it's API, which is very good, that will use the parser on your system (Xerces). I would definately recommend JDOM.

How to upload and download files using FTP to a server(webserver) in JSP

I have to upload and download multiple files Of(size >5 MB)using FTP to a
Server(webserver) in JSP
how to do that ?

Or he could create his own tag libraries, no? :)One supposes that, technically, one could create a taglib wrapper around an existing FTP library. There might be licensing issues with distributing that taglib wrapper.
Of course, one could find the FTP RFC online, read it, and implement one's own FTP client implementation, complete with a tag library access point.
