Java starting Guide is not working

Java SDK
,
1

Hi, I just started to evaluate Couchbase with the Guide at Start using SDK
I installed the newest Enterprise Server on my Windows 10 machine.
It is up and running. Bowser is showing
Server Name: 127.0.0.1:8091 Uptime: 3 hours, 51 minutes, 21 seconds OS: win64
Version: 4.5.0-2601 Enterprise Edition (build-2601)
under http://localhost:8091/ui/index.html#/servers/active?openedServers=127.0.0.1:8091

Running the example leads to this stacktrace:

What have I done wrong?

Is it anniversary edition? If so, you’ll want to use Couchbase Server 4.6 DP. To verify this is the problem, you may want to look at the list of cluster nodes in the console and see if the localhost node is healthy.

If that’s not it, have a look to verify you don’t have anything blocking port 11210. The symptoms seem to correlate to that.

Also @brett19 may have a tool that may identify what’s going wrong here.

An my second machine, I test against the 4.1.1 community edition. The same code is running as expected.
I’ll try to uninstall the enterprise edition and reinstall the newest version…

http://www.couchbase.com/ is not working well.

On Firefox I’m unable to sign in.

On Chrome I’m able to sign in, but the download triggers a not working route: http://www.couchbase.com/nosql-databases/downloads?gtmRefId=FixedCTA-Download#download_form
I’m signed in. My email address is known :wink:

Only in Edge the route is showing a form to be filled (unnecessary because I’m logged in)

4.6 DP is working fine…

It is not a good sign if an official version has such problems…
