Hi, I'm using this great product to wrap my java application (some kind of client multimedia player) and I'm totally satisfied with it. So I'd like to first say thanks for developping it. Now, let my explain my will : my application is relatively unstable yet, and some conditions can make its lauch impossible. I have set /wrapper.max_failed_invocations /with value 5. After 5 failed invocations, the wrapper stops invoking, like it's supposed to do. Now, I'd like to be able to "catch" this "giving up event", and for example trigger the invocation of another main class on this giving up. My purpose is to keep a trace of these events (e.g. in a local file) because they reveal important information to me. Is there any way to do this? Thanks in advance! Seb PS : for now I regularely check the file "wrapper.log" and look inside if I can find the pattern "There were 5 failed launches in a row, each lasting less than 300 seconds. Giving up." -- Sébastien CHATEAU Mirane SAS ------------------------- sch...@mi... www.mirane.com ------------------------- Tel : 05 57 77 12 15 Fax : 05 57 77 34 90 |

Sebastien,
This kind of thing is in the works for a future version. But for now it
is not
directly supported.
There is a simple workaround however. Write a new main class. In it
simply do the following:
public void main( String[] args )
{
if (WrapperManager.getJVMId() <= 5 )
{
MainClass.main( args );
}
else
{
RecoveryClass.main( args );
}
}
Then increase the max failed invocations from 5 to 6.
Cheers,
Leif

Hi Leif, just thanks for your fast and appropriate answer. My problem is
solved. Do you want to marry me? ;)

Are there hooks into these JVM lifecycle events (ie some way of notifying
the outside world that a restart has occurred?)

There are requests to be able to execute arbitrary external commands when things like restarts take place, but they are not yet implemented. The only way to do this right now would be to check the WrapperManager.getJVMId() method when the JVM starts up and do any notifications from there if the id is greater than 1. Cheers, Leif |

Not currently. There are requests to be able to execute arbitrary
external commands
when things like restarts take place, but they are not yet
implemented. The only way
to do this right now would be to check the WrapperManager.getJVMId() method
when the JVM starts up and do any notifications from there if the id is
greater than 1.

Leif
