Uploading File To MySQL from HTML form via Servlet

Question

Hello all !
I hope this is better place to ask.
I'm working on simple Servlet/Jsp application trying to hold to MVC pattern and got stuck on uploading file to MySQL db.
Here's what I'm trying to accomplish:
1) client submits a JPEG image via a simple html form on a webpage.
2) JPEG is put into a database table, column field of type BLOB.
3) Servlet processes the request, gets a connection to the db and inserts the image into the table.
4) after that user is able to retrieve an image from db and display it in JSP page.
This is pretty much the same task Angela was trying to do here:

I could use her snippets if i knew what is what and decided to figure out this myself. Aftet some investigation i found out that i need to import org.apache.commons.fileupload.*;which i found here: http://jakarta.apache.org/commons/fileupload/
what am i driving at ?
-----------------------1-----------------------
After first line of code
boolean isPart = FileUpload.isMultipartContent(request);netBeans 5.5 beta2 with bundled Tomcat 5.5.17 underlines this with warning saying that
org.apache.commons.fileupload.FileUploadBase
has been depreceted
is it a reason for concern ?

Is it actually good idea to store images in db as blob ?
what about large ammounts of text ?
thank you

Answer 1

is it a reason for concern ?Yes.
You should take a look at the method in the documentation and find out exact reason for depricating it.
If it is depricated becouse they going to remove it in the future you should use the new alternative method becouse if you use the old method your app will not work in the future releases of the API.
If it is depricated becouse it is not safe to use the method you should clearly understand the risks involved in using the method and see if that can give you any trouble in your project.

Is it actually good idea to store images in db as
blob ?I think that it is ths best option available when you want to store binary data
what about large ammounts of text ?You can use clob columns.
By the way when you store files in the database its better you put some extra columns to store the file name and file type(mime) becouse you cant directly detect those things later by just looking at the data of the file.
