Subject RE: Fail over: ActionForm's FormFile attribute is null .....(Weblogic8.1 cluster)...
Date Wed, 17 Sep 2003 16:01:10 GMT
Daniel,

I wasn't responsible for setting up the environment but here is what
happens.  When I finish uploading the file, we take down the target machine,
that proccess the request,  and let the failover machine take over.  Every
thing else working fine except when you access the ActionForm in the session
that has the FormFile attribute, the attribute is null and the
NullpointerException being thrown.  Is this because the DiskFile class that
implement the FormFile interface is not serializable.  If this is the case
what do I need to do?

Thanks,

--danny

I don't know how to solve your problem -- but does your cluster support
failover during file uploads?  If so, can you describe how it is configured?
we are trying to provide this functionality...

thanks,
daniel

Hi all,

I have an ActionForm used for fileupload that has an attribute of type
FormFile, that become null after a file being uploaded and on the failover
machine in our cluster environment it become null and throw a
NullpointerException.  Does anyone know how this can be fix?

Thanks,
