Bug: omero/webgateway json 404

[wmoore]

If users deploy web under /omero/webgateway etc then the image viewer gives a 404 for the json because the /omero/ is not included in the url.

See ​https://www.openmicroscopy.org/community/viewtopic.php?f=5&t=6359
(and some private message with more details).

This is not exactly a problem of a custom prefix. Issue is related to the ​viewport_server variable.

From the forum post I can see that he was trying to access image via webgateway directly and that is true that the line above has /webgateway hard-coded if any vieport_server is not set. This string definitely should be replaced by URL dispatcher. Although that problem should be easily resolved by launching full viewer from ​http://omero/webclient... see how ​viewport_server is set here.
I can confirm that we deployed teaching tool on custom prefix and JSON response is HTTP 200.

Why did he use [...]/omero/webgateway/render_image/14350/ rather then webclient?

[wmoore]

We're using /webgateway/ viewer because this is a public data and a simple way of exposing image viewers (but not the webclient UI itself) is to use ^{webgateway in the url filter. It's what we suggest in all our docs and what we've done ourselves on nightshade - E.g. ​http://users.openmicroscopy.org.uk/~rkferguson/public_share_demo.html}
