Is it possible to not be able to move or delete Connection and Anchors?

Alex,

yes, simply override getDeleteFeature and getMoveAnchorFeature in your
feature provider. Returning null or an instance that returns false on
canDelete/canMove will do the trick.

Thanks Michael.

I tried your suggestions and they work. However, I still am able to select a connection and move its endpoints to another anchor. I override getMoveShapeFeature() that returns null, but it does not apply to Connections since they are not Shapes.

Alex,

moving an endpoint means reconnecting a connection. For this the reconnection feature is asked, default implementation is DefaultReconnectionFeature queried from IFeatureProvider.getReconnetionFeature.
