Hi Mike Curwen,
Tx for the reply.
About my first problem, why i hurry for finding out the workaround is, Our project already went live. If customer reports any defects, we are fixing it & sending the same to him. In order to update even a single bean, we are forced to bring down the server. In initial stage it is okay. But customer is not happy about this procedure. They want server to be up 24 hours a day.
I'll be ver ymuch thankful if anyone give some solution on this.
My second problem is, yes it is really a problem.(500 error again not coming from cache, because, i've removed the cache, as well as i've seen from the log that request went to server again.
This is not a big issue for me now. I'll appreciate, if anyone explains why this is happening like this.
