retrieve session data stored in db using JDBCStore.
Hi, I have been successful in saving the sessions to my mysql db, using the given code in my server configuration file. Store className=org.apache.catalina.session.JDBCStore connectionURL=jdbc:mysql://X/xx?user=zamp;password=zz driverName=com.mysql.jdbc.Driver sessionIdCol=id sessionValidCol=valid sessionMaxInactiveCol=maxinactive sessionLastAccessedCol=lastaccess sessionTable = app_sessions sessionAppCol = context sessionDataCol = data / this stores the session data as a blob in the db. So my questions are, Can we assign the blob data directly to a new session, so that this new session assumes the state of the session in the db? Can we retrieve and edit information from the blob? if YES, please furnish some sample code or at least direct me towards the solutions. if NO, what other ways can we go about, to achieve session persistence(not just validation as in cookies but a complete session state snapshot). -- View this message in context: http://www.nabble.com/retrieve-session-data-stored-in-db-using-JDBCStore.-tp23020556p23020556.html Sent from the Tomcat - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
Expose URL via Apache / Tomcat Load
Hi Would the same work with Apache / Tomcat Load Balanced mode Configuration for single installation of the web application acme www.acme.com being exposed to INTERNET www.acme.com/adminbeing exposed to INTRANET Reason : The application uses a single DB to request of orders (from Subscribers) and same URL with *admin* would process the orders ( Internal Employees) and should not be exposed to outside world. Is there any Configuration with in Apache or Tomcat to achieve the same? With regards Karthik

Surely modifying the session using the API provided by the Servlet spec is a) safer and b) easier. if YES, please furnish some sample code or at least direct me towards the solutions. if NO, what other ways can we go about, to achieve session persistence(not just validation as in cookies but a complete session state snapshot).

Removal of (or disable) /admin for the user manager
Tomcat 5.5.23 on Linux Hello, I have a question in reference to Tomcat's Tomcat Manager's default page 'Tomcat Web Application Manager' When I log in, as user 'manager' to that page I like to either: 1) remove the row '/admin' all together, 2) if I can not do that, I at least like to prevent the ability to do any of the actions mentioned in the 'commands' column (start/stop ,etc,etc).

Announcing new Apache Tomcat installable Live CD appliance
Hi everyone, I'm one of the developers for TurnKey Linux, a community oriented open source project developing a family of free, Ubuntu-based installable Live CDs which are lightweight and optimized for ease of use in server-type usage scenarios (e.g., LAMP, Joomla CMS, Drupal, Ruby on Rails): http://www.turnkeylinux.org/appliances We're proud to announce the release of TurnKey Apache Tomcat, an installable live CD of Apache Tomcat that can run on real hardware in addition to most types of virtual machines (e.g., VMWare, VirtualBox, Parallels, Xen HVM). It is designed to provide users with a pre-integrated, auto-updating, turn-key operating system environment that is carefully built from the ground up with the minimum components needed to run Apache Tomcat with maximum usability, efficiency, and security. Basically this is an extremely easy way to get up and running with Apache Tomcat in just a few minutes. Feature highlights: * Auto-updated daily with latest security patches * SSL support out of the box * Elegant Web administration interface (Mac OS X themed) * Minimal footprint (212MB) Full details: http://www.turnkeylinux.org/appliances/tomcat BTW, this type of pre-integrated, ready-to-use system is typically called a software appliance: http://en.wikipedia.org/wiki/Software_appliance Take a look and tell us what you think!

JSP: No suitable driver found
Hello All,
I have what should be a simple problem, but can't seem to resolve it.
Basic JSP using a non-pooled connection:
sql:setDataSource var=myDS
url=jdbc:oracle:thin:@host.example.com:1521:ORACLE
driver=oracle.jdbc.driver.OracleDriver
user=username
password=password
/
I'm getting the exception:
javax.servlet.ServletException: javax.servlet.jsp.JspException: Unable
to get connection, DataSource invalid: java.sql.SQLException: No
suitable driver found for ${myDS}
I've confirmed that the host, user, password are correct. Of course it looks
like a classpath problem, but WEB-INF/lib contains: jstl-1.2.jar ojdbc14.jar
standard.jar
Can anyone suggest what else I might try to resolve this?
Thanks!

Hmm... does it say ${myDS}? Maybe you get that exception when you try
to /use/ the connection. Is sql:setDataSource part of the JSTL?

You might try putting your JDBC driver in Tomcat's top-level lib
directory (lib/ for TC6, common/lib for TC5) and trying that. Just
remember that there should only be one copy of your JDBC driver
available on the CLASSPATH (which you should NOT set yourself... Tomcat
takes care of all of this for you).
Definitely don't downgrade to classes12.jar as Martin suggests.
Generally speaking, there are no JDK version-specific JDBC drivers. You
should get the more up-to-date driver that makes sense for you.
Also don't downgrade the JSTL (if that's what you are using): you should
use the most up-to-date version you can get for that, too.
FWIW, you should consider using a pooled datasource at some point. Maybe
setting that up, now, wouldn't be a bad idea.

RE: reading jvmRoute property specified in server.xml
We have Quartz jobs running in back ground. It needs to know whether this instance has to run the job or not. Earlier we use to catilina.base which we can read as System property . now all the servers have the same instance names..so i am just thinking is there any way this property will help to get the unique name to find out the instance. currently i have resolved this by the combination of catilina.base with java.net.InetAddress.getLocalHost().getHostName() which makes unique..

Re: retrieve session data stored in db using JDBCStore.
Why? The risk is that you will introduce inconsistencies into live sessions. Surely modifying the session using the API provided by the Servlet spec is a) safer and b) easier. As we are dealing with sessions that are no more accessable, this action would have no effect on any live sessions thus no inconsistencies. if YES, please furnish some sample code or at least direct me towards the solutions. if NO, what other ways can we go about, to achieve session persistence(not just validation as in cookies but a complete session state snapshot). Isn't that happening now? Yes but only at server restarts. Can we assign the blob data directly to a new session, so that this new session assumes the state of the session in the db? Why? The session manager should be doing this for you. Again this happens only at server restarts. tomcat version = 5.5.20, jvm version = 1.6.0, os version = windows xp sp2. Ok. what i am trying to implement here is session persistence across browser restarts. ie. I would like to maintain the session state even if the browser is closed and restarted at which point a new session is started. we know that the session exists in the db for the time that is specified in 'sessionMaxInactiveCol=maxinactive ' so, even if the browser is closed and the session is destroyed at browser level it still exists in the db. (we can prolong session expiry using: session.setMaxInactiveInterval(2 weeks);) now i would like to persist the old session by maintaining the session id inside a cookie, and compare this id against the session id stored in 'sessionIdCol=id ', then copy the session data stored as blob in '''sessionDataCol = data ' and assign this data to the new session. thus i would be able to regain the last session state in which the browser was closed. once the transaction is complete i would remove the old session from the db. Is this possible, if yes how? -- View this message in context: http://www.nabble.com/retrieve-session-data-stored-in-db-using-JDBCStore.-tp23020556p23032552.html Sent from the Tomcat - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
