Hello Jean Marie,
I had finally some time to figure this out properly. My plugin makes use of the imageJ 5.5 plugin site and is trying to connect to the server via a gateway.
However the gateway class is in two locations once i have both the 5.5 update site activated as well as the omero_ij-5.5.10-all.jar file in the plugin folder
Both contain the Omero.omero.gateway class. The last jar directly in the omero/omero subfolder of course. For the update site in the omero-gateway-5.5.3.jar file.
I need the update site for the Omerolocation class. which i am using to access the images.
Located in the imagej-omero-0.9.0-SNAPSHOT.jar file.
Of course i can add this manually, but i would like it if users of my plugin would just have to activate a few update sites. This is the easiest way to distribute i have found out, therefore i would like to keep it that way.
If you have any suggestions they would be more than welcome
