Few things which you need to clarify. What do you mean by sending an image to database? Is this persisting to database. Then why are you bothered about servlets.

Or is this sending an image over HTTP to some remote server, which in turn takes the responsibility of persisting to database and send back an ack. I guess this is what you are looking for.

this is similar to file upload (though I have not personally worked on this). Apache has an open source project called FileUpload which provides this facility. Once you get the file at server, persisting to database is a different operation. Google on apache FileUpload and you are presented with abundant examples.

Happy coding.

There are many examples , that are aviable in internet .
I will tell you the starting point , on to the Form (to upload images ) , make it as enc

<FORM NAME="InputForm" ACTION="test.jsp" METHOD="POST" enctype=multipart/form-data>
<P><input type=file name="filename" size=80>
<P><input type="submit" value="Upload File Test">
</FORM>

and in your Servlet use the PreparedStatement use this

InputStream smallStream = (InputStream) new FileInputStream(smallFile);
    pstmt.setBinaryStream(2, smallStream, smallFileLength);
    pstmt.executeUpdate();

and use Blob as Datatype for that Database column .
try it.
