It depends on what kind of data you want put into a BLOB. Let's consider the table:
create table b1(id number , b blob);
If your data represented as hex-string you should use TO_BLOB function
insert into b1 values(1,to_blob('FF3311121212EE3a'));
SQLPLUS also shows BLOBs as hex-string
select * from b1;
----- -----------------------------------
ID B
----- -----------------------------------
1 FF3311121212EE3A
Please refer Oracle documentation on Using LOBs

Look at this If file is stored on a server in the folder described with CREATE DIRECTORY then it is possible to use DBMS_LOB package to read the file and put it into a table. Regarding to JSP there are two ways, I think. 1) just extract to the folder accessable for the web-server, and give URL to the client. 2) load file and return it directly as http-response. See examlpe
