oracle jdbc loses network connection after a while
hi, I have a java program that uses oracle thin driver to connect to Oracle 9i db on unix box. If there is only 2000 records to process, the program works like a charm. However, when I tried to process 30000, after 5 minutes or so, I get a sqlexception:network adapter cannot establish connection...- maxpower1

how count active users
><body onUnload="logout()"> Sedj, In my humble opinion, body unLoad will be called everytime a page unloads. It will work fine if you have this script of logout.jsp page and a user happens to click on the 'X' button instead of gracefully exiting through the application exit's function. However...- maxpower1

window.confirm default to Cancel button
thanks for the reply. I let you know if I find anything. >Are the results that dramatic if they accidentally hit 'OK' when they meant to hit 'Cancel'? The web-based app that I wrote is used to move heavy items (a couple of thousand lbs each) by cranes. It's an equipment-managed app. Yes the...- maxpower1

how count active users
If I learned form my experience, using session variables to keep track of things(# of user logins) are painful. What if a user clicks on the 'X' button instead of exiting gracefully through your app 'exit' function. That means, the # of users logged in and log out will not be correct, until the...- maxpower1

global JNDI resources tomcat5
J2EE offers a more suitable implementation where you can define all your <env-entry> in ejb-jar.xml at the <enterprise-bean> level. I'm not sure whether you're using J2EE or not. Think about it though, only starting JDK 1.4, JNDI is incorporated into java. SDK 1.3 doesn't have this feature... -
global JNDI resources tomcat5
may be this is what you mean. I have db JNDI resource declared at the server.xml level. Then I use InitialContext object to retrieve it. <ResourceParams name="jdbc/MyDB"> This way, multiple web apps can access server.xml for the values. ~za~ You can't bring back a dead thread! -

Binding subcontexts to JNDI read-only Context in Tomcat
i am currently preparing for my EJB exam. I finished my JNDI section and if I'm not mistake, you can remove/add the string ONLY after java:/comp/env. I.e, DataSource ds = (DataSource)ic.lookup("java:comp/env/jdbc/MyJdbc"); in the DD:- <entity> ... <resource-ref>... -
Binding subcontexts to JNDI read-only Context in Tomcat
ben, I'm not sure whether you can use the 'java:' alone. I never tried to bind but here is the call that I usually use when using JNDI(it works all the time):- public static String sEnvConst = "java:comp/env"; public static String sJDBC = "jdbc/My_App"; //This is how I... -

Difference between Vector and ArrayList
1. Vector and ArrayList are lists implementation. Synchronized means "thread safe" which adds a performance hit(heavy weight). On the other hand, ArrayList is not "thread safe". I use arrayList a lot more because I usually need it to display a bunch of read-only database... -
