need to read the blob and convert it into a file

[Adeel Ansari]

hi all,

I need to convert the oracle blob into a file and probably show it on my JSP or html page. blob could be of a jpg, gif, pdf, doc, txt, bmp, etc.

what i am doing is uploading a file (using apache DiskFileUpload), then gettin bytes (using fileItem.get()). now i need to store it in oracle as a blob, upon retreiving i need to convert it back into a file.

any suggestions...
thanx

I'm assuming you know how to use JDBC to connect to Oracle. Just use PreparedStatement.setBytes() to write the bytes to a Blob. ResultSet.getBytes() will get them back.

java.io.FileOutputStream.write(byte[] bytes)
