hi there,
Hi,
could you please send me (to [EMAIL PROTECTED]) the err.log file of
java org.xmlBlaster.Main -dump[socket] true -call[core] true -call[dispatch] true -logFile err.log -logDevice file,console
when the problem occurs? It should contain the login sequences of A and B and the publishes and subscribes when the error happens,
thanks Marcel
i'm pretty sure this is about my lack of understanding about how XMLblaster messages work, but i cant figure it out at all. here's what happens.
in my environment, application A (which is a publisher) needs to send some commands to application B (which is a subscriber); application B should respond with a ptp message back to A upon executing the command. when it is first started, application A needs to make sure that application B is alive, therefore it goes into a loop and posts dummy commands for application B, every 3 seconds, until it gets a response. these dummy messages are sent with the following <qos> tag: <qos><expiration lifetime="3000"/></qos> (i also tried adding the <forceUpdate>false</forceUpdate> with the same results). B subscribes to the messages published by A with the following <qos>: <qos> <persistent/> <multiSubscribe>false</multiSubscribe> <initialUpdate>false</initialUpdate> <local>false</local> </qos> (again, i also tried adding a <history numEntries='20' newestFirst='true'/> - same results).
everything is fine if application B is already started when A starts - a response is sent back from B to A, and A breaks off that loop and enters normal operation. however, if A (the publisher) starts before B, a lot of times B doesnt seem to receive the messages published by A (i can say this since B would log every single message that it receives). again - sometimes it does receive them, sometimes it doesnt - and i cant understand why this is happening. both my apps are written with the C sockets library.
can anybody help with an advice to make this work consistently?... thanks. (let me know if more information is needed from me.)
