Hi, I want to lock a record of a table in a database throug servlet-HtmlPage-sevlet process as following flow: 1. in a beginning page(Html) input query condition (such as a primary key of a record) then call 2. servletA select(query) the record to display. lock the record at the same time.return 3. a new page which display the record.edit the record.press "Update" button,call 4. servletB carry out a transaction to database, update the record then unlock the record for other browsers to use this record. I should keep the lock of a record during 2 and 4, then unlock it at the end of 4. the question is can servletA and servletB be the same servlet? How can I keep the lock of a record during 2 and 4 since 3 is necessary? thanks in advance VictorJ _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.
