is HTTPS URL supported in oomph.redirection.setups ? [message #1746436]

I have a custom catalog/index hosted in an local server.
When I switch from http:// to https:// Oomph Installer is not able to find the catalogs anymore.

The eclipse-inst.ini looks like this:
-Doomph.redirection.setups=index:/->https://<my-server>/setups/

Should this be supported?

Yes definitely this should be supported. I expect it just to work. Certainly I have customer project setups accessed via https that require basic authentication that do just work so in general ECFURIHandlerImpl should handle the required authentication properly...

You could try using -Doomph.setup.ecf.trace=true to get more detailed tracing information printed to System.out so you might be able to see what's going wrong.

Does this server require a user/password for access? Does it return a HTTP_UNAUTHORIZED/401 when accessing a resource without credentials? In my customer project the server is quite funky in that it returns a 404 after providing the correct credentials because the server also relies on cookie that's acquired from visiting the login page. That's supported too, but I've not yet documented how. Please let me know what information you get back for the tracing so I'll be better able to help provide the details (and fix any problems if there are any)...

One thing I just noticed debugging proxy related problems is that the prompt for the proxy password that I'm trying to add happens so early in the startup processing that there is no a Shell available yet. So the password prompting is bypassed. I'm quite sure the same thing would happen if the setup itself needs password prompting. So I'm hopeful that improving the proxy handling with proxy password prompting will also fix this problem because with the changes I'm working on, the password prompt will definitely appear. Hopefully that is indeed your problem. An ECF trace from you will still be helpful...

Thanks Ed.
-Doomph.setup.ecf.trace=true helped a lot.

I can see the SSL certificate validation failed. Most liked this is caused by the usage of a self-signed certificate that we use on this internal server.

Here's the log:

Is there a way to disable the SSL verification in order to avoid to have to add the certificate to the list of trusted certificates?

This is very low level. I don't know about that. I tried Googling "java disable certificate validation system property" and found some stackoverflow questions. All of these things suggest it's a bad idea to try to disable such checks with suggestions about importing the certificate so that it's considered valid.

Yes, that's true, it's a bad idea to disable certificates in a generic way, but having to import it in every JRE we use (remember, we have a new JRE version every 3 months), that's not very practical.
Anyway, I imported the certificate and now it works fine, so I need to figure out how to workaround this, in order to not force users to install the certificate every time they change the JRE. Maybe I could distribute the Installer zip with a pre-configured JRE inside.

Thanks for the support.

Did you use keytool to import it? Perhaps we could provide a way to automatically import a certificate into the JRE of the installer and into any of the other JREs that Oomph discovers...

Hi,

did you solved the problem already?
I figured out, that this problem does not occur on my own machine but only on my colleagues one. I have no idea how to figure out what we do differently.

Do you perhaps have a newer JRE installed than your colleagues? A newer JRE/JDK might well include more recognized root certificates; I know that solved one problem like this for me testing market place client listings...
