Hi Philip,
what version of the Neo Shell are you using? I tried running with the
b6 version and ran into the same problem as you did. However,
everything seems to run fine using the trunk code, even the latest
RC1-SNAPSHOTS work fine (e.g.
http://m2.neo4j.org/org/neo4j/shell/1.0-rc1-SNAPSHOT/shell-1.0-rc1-20080319.221229-7.jar),
running against neo4j-1.0-b6. So, i think the docu should just be
updated with pointing out that b6 of the shell is not working as
expected.
As for the starting code for the NeoServer, I can't see a Transaction
being committed before the LocalNeoServer can accept NeoShell remote
requests ... at least not in the NeoShell code (see e.g.
StartRemoteClient,java, starting a LocalNeoShellServer.java which does
roughly what you have in the NeoTest code). Not sure why this has to
be there, what was the error you got without doing that?
WDYT?
