OMERO connection in KNIME 4.0

KNIME Extensions
1

Hi all,
I was just trying to migrate one of my workflows from 3.7.2 to 4.0 however the OMERO connection node does not work. Is it generally not compatible with KNIME 4 yet?
The error I get reads “Connection to … failed
javax.net.ssl.SSLHandshakeException: No appropriate protocol (protocol is disabled or cipher suites are inappropriate)”
Cheers, Peter

Hi @PeterZentis,

can turn on debug logging and post your KNIME log after executing that node again? This would tell us more about what is going on.
best,
Gabriel

Hi @gab1one,

Thanks, for looking at this!
Here come the log file and my test workflow:

knime.log (27.1 KB)
Kollagen_OmeroToIlastik.knwf (3.8 KB)

Cheers,
Peter

The problem is caused to some SSL incompabilities in more recent java versions:


Downgrading the JRE in Knime fixes this issue.
