Dubuisson, Jr. Sent: Wednesday, 18 December, 2002 12:11 AM To: [EMAIL PROTECTED] Subject: session timeout setting I have a site written in JSP that uses session info to validate user's sessions. I want to change the default timeout of the session from 60 mins but I'm not sure what is controlling this or how/where to change it. Here is more info to help figure this out...if anyone has any ideas I would greatly appreciate it. My initial JSP page has a login which, when validated, sets a cookie that stores the session ID. Every page thereafter, upon initial load, checks the current session ID against this cookie and if they don't match, the user is directed to re-login. My users want a longer timeout but I'm not sure where to control this (maybe this question is for the Tomcat listI just don't know).

Re: static initialization
Hi, How much data you expect from your select boxes ?? If it is a small amount, I would suggest that you store it in a Vector and save it as a application attribute. Then you static methods can "query" the Vector instead. You only need to update the Vector if there is any changes to the these select boxes' data (I presume that will not happen often) HTH Best Regards, Lim Yong How Software Engineer Ryeson Security International 180B Bencoolen Street #10-01/02 The Bencoolen Singapore 189648 www.ryeson.com <http://www.ryeson.com> The information contained in this e-mail message is intended only for the use of the person or entity to whom it is addressed and may contain information that is CONFIDENTIAL and may be LEGALLY PRIVILEGED and exempt from disclosure under applicable laws.

Each method willspeak overto the DB and get the values as ArrayList. These values will be loaded in the HTML pages as option values of the select boxes. Here is the sample code snippet i have used . I have made the OWNER_LIST as private static. private static ArrayList distinctOwner(String tableName) { Connection conn = null; PreparedStatement pstmt = null; DBUtilities DBUtil = null; if(OWNER_LIST == null) { try { OWNER_LIST = new ArrayList(); DBUtil = new DBUtilities(); conn.setAutoCommit(false);; String sql = "select distinct owner_name from " + tableName + " order by owner_name"; ResultSet rs = DBUtil.doSelect(sql); while (rs != null && rs.next()) { OWNER_LIST.add(rs.getString(1)); } rs.close(); } catch (Exception e) { System.err.println("Problem getting distinct owner from " + tableName + " order by owner name"); } finally { try { pstmt.close(); } catch (Exception e) { } try { DBUtil.closeConnection(); } catch (Exception e) { } } } return OWNER_LIST; } I have made all these ArrayList as static so that they will be populated only once in the server. Typically I amtrying to catch the records. Some transaction during the application may change the DB records. In such scenario i have to call a Refresh such that this makes all the values of the Helper class again to null so that when next time somebody clicks on some item Helper class has to fetch the new values from the DB. My question is supposing that when a user clicks on the Refresh buton and at the same time some other user is looping thru the ArrayList in their jsp pages, it will surely thro an error. How to prevent this. I thought of putting the ArrayList initialization as synchronized but in my Helper class i have many methods (25). That means i will be having 25 Synchronized blocks which might become too overhead for the webserver. Any nice ideas and suggestions to resolve this ishighly appreciated.
