Answer 1

i have servlet read from DB and set result at
vector Vectors are normally discouraged because they're Synchronized.
Why don't you read the ResultSet in an ArrayList Collection instead?
and put it in session attribute to jsp that
read it and print itInstead of putting the ArrayList of results (or in your case Vector) into the Session, you could store it in the HttpRequest attribute instead.
HttpRequest attribute has an advantage over HttpSessions
1) The Request Attribute is available through the scope of the Request
But the session attribute can expire at any time. The session attribute will not work if the page gets cached by the browser.
but this view does takes 10 sec on my computer
and on hosting server If it is taking that long you may want to optimize your JDBC code.
1) Use Connection Pooling
2) Prepared Statements
3) RowSet
4) Check the SELECT statement
it shows date un complete what is do you thing it
wrongHard to say without looking at the code.
