This seemed odd. In the logs there was a line from the Elastic container saying 
that the parameter being sent by James was deprecated. This was logged as a 
warning, rather than an error though. The next line in the logs was from James 
saying that it had had a 400 response from Elastic, and therefore was exiting.

I thought I’d tweaked the logging level but I wasn’t seeing any additional 
output. Seems like this is the week to learn all about log4j though, so I’ll do 
some more reading and experimenting.

My ultimate aim is to have something with JMAP support, which is why I started 
with the distributed app example. However, I’ve switched to the Cassandra-app 
example and that seems to be compiling and running okay. Next step is to add in 
my own custom module to replace the Cassandra domainlist. If I can get that 
working then I’ll try and add in S3 blob storage similar to what’s in the 
distributed app.

I appreciate that this is an advanced topic, so thanks for your help and 
patience. Doubly so as I believe you’re supposed to be on holiday at the moment 
:-D

Regards,

Felix

This should have no impact on the startup.

you can play with logback.xml to setup the logging level.

But I suspect you have another failure somewhere aborting / hanging the
boot...

Setting up a custom assembly server is an advanced topic. While I can
answer a few question on this ML on a pretty informal way, I can provide
support if you need to.
