Cannot send a transaction recovery message to the server since the protocol version of EJBReceiver Remoting connection EJB receiver doesn't support it

[superalex]

hi, following this guide (https://docs.jboss.org/author/display/AS72/EJB+invocations+from+a+remote+server+instance) i have set up a connection between two eap jboss (6.1 client, 6.0 server) and all works fine: on client there is a web service that call a remote ejb on server with lookup.

but on client server log i read this message every minute and i don't know what is it and how to solve...i think is some configuration on server jboss but i didn't find anything on the web.

i know also that a warning is not an error but i would be happy if i manage to eliminate.

what is that??

thanks

Transaction recovery of EJB remote resources was introduced in EAP 6.1 and EJB client library that's shipped in EAP 6.1.  Since you are using EAP 6.0 as the server to this client, it's not able to initiate any transaction recovery against that server, since that support isn't available in 6.0.

thank you..is there a way to eliminate warning message??

[jaikiran]

One way is to configure org.jboss.ejb.client.remoting package logging level to ERROR. But that would mean you won't see other INFO/WARN messages from that package too.

The other way is to specifically exclude log message with id EJBCLIENT000061. Last time I checked, IIRC, I think James (from JBoss Logging) mentioned that it's possible to do that with the configurations, although I don't remember how.

ok..but i think that i'll upgrade the server jboss to 6.1 because i have some problem:

in client jboss there is a web service which call the remote bean method on server jboss through lookup...now i see that the first or the second time the web service method call goes well, but after some time if i call it the remote bean method get stuck for several seconds, after that it crash with exception like "the channel is close" or whatever...then the method is working again...do you think this is correlated with warnings i posted before??

I have also some doubts on how to manage context..i don't know if it's better to create a new InitialContext then do the remote lookup everytime web service method is called (closing the context beforer method returns ), or do these only the first time, reuse the context and remote bean every time and not close context
