Hi, Martin
i'm running memcache session manager and Jboss5.1.0GA.

it work, handles tomcat failover, but did not failover memcached.

i have following jars in ${jboss-5.1.0_home}\server\default\lib:
msm-all-memcached-session-manager-1.5.0-SNAPSHOT.jar
msm-all-memcached-session-manager-jbossweb2-1.5.0-SNAPSHOT.jar
msm-all-msm-javolution-serializer-1.5.0-SNAPSHOT.jar
javolution-5.4.3.jar
memcached-2.5.jar
juli-6.0.28.jar
( I did not use kryo. when I use kryo, can not access the
Administration Console, and jboss prompt internal error. The main reason
is kero can not be serialized java.util.concurrent.ConcurrentHashMap,
etc. )

now, there're jboss1(j1) jboss2(j2) memcache1(m1) memcache2(m2) ,
they're working.
And, m1 has sessionids:

bak:validity:4AFCA68FE3DE6AC970E84A82EB2B5616-n2
bak:4AFCA68FE3DE6AC970E84A82EB2B5616-n2
m2 has sessionids:
validity:4AFCA68FE3DE6AC970E84A82EB2B5616-n2
4AFCA68FE3DE6AC970E84A82EB2B5616-n2

Then, I stop m2, m1 did not failover, in this case, m1 should
have 4AFCA68FE3DE6AC970E84A82EB2B5616-n1, but it's not, it has new
sessionid: BBC4133E6D12ED19896F9ADF0A2622FB-n1. so, browser page need to
re-login, and session data loss.

i gets sources of msm from github, but, i do't know solution.

ths, I hope you can give me some advice.

    Hi, Martin
    this problem has been solved.

    today, i looked at the source. I found “thisAccessedTime”, is wrong ,
    it's different in Tomcat and Jboss. the following:

    (Original)
    public class SessionValidityInfo
    {
    //......

    public boolean isValid() {
    long timeNow = System.currentTimeMillis();
    int timeIdle = (int)((timeNow - _thisAccessedTime) /
    1000L);
    return timeIdle < _maxInactiveInterval;
    }
    }

    Should be modified to:
    public class SessionValidityInfo
    {
    //......

    public boolean isValid() {
    int timeIdle = (int)( _thisAccessedTime / 1000L);
    return timeIdle < _maxInactiveInterval;
    }
    }

    The above has been tested.

    In addition, when accessing the administrator console, always return to the
    login page.

    good to hear you solved it!

    In addition, when accessing the administrator console, always return to
    the login page.
    So this issue is still there? What's special about the admin console?
    Maybe you can turn on debug logging to see if there's an issue?

    Btw, when I tried to create a msm version for jbossweb I couldn't manage
    to get integration tests running (due to a changed/incompatible embedded
    tomcat class IIRC). Therefore I canceled working on jbossweb
    integration, the support I can provide for this is also fairly limited.

    Cheers,
    Martin

    hi, Martin:
    Anyway, thank you very muth.

    About Administrator Console, it's
    ${jboss-5.1.0.GA_HOME}/server/default/deploy/admin-console.war, it was
    provided with jboss.

    When i viewed it, i found that the JSESSIONID is inconsistent in
    Chrome and Memcache. so, always return to the login page.

    But, my web project and jboss's other project are work.

    About this, i will continue to solve it .

    Cheers,
    franklin
