OPC-UA server problem with certificate?

[jbarbosa29]

Hi Jens,

I've a problem connecting to a OPC-UA server. The error is depicted below. Can anyone, help me solving this issue?

Thank you.

Sorry, i did not work with authenticated connections so far. And that is where this problem occurs, it seems.

This looks strange to me. But from the stack trace it looks to me as if this is a problem in the OPC UA layer in Eclipse Milo. So I would kindly ask you to raise an issue with them.

I published a new version to Maven Central a few minutes ago (version 0.1.1). This should fix this issue.

It would be great if you could give it a try and give some feedback. Thanks!

[jbarbosa29]

Thank you so much. The problem is now solved. Nevertheless, the feature:repo-add mvn:de.dentrassi.camel.milo/feature/0.1.1-SNAPSHOT/xml/features should be feature:repo-add mvn:de.dentrassi.camel.milo/feature/0.1.1/xml/features

It should be 0.1.2 in the most recent README ... or did you spot another location?!

[ctron]

I was wrong. It should be 0.1.1 instead of 0.1.2 ... fixed this!

[jbarbosa29]

No, now it's fine. Good work.

Thanks a lot for reporting and testing!
