Migration Issue

[Terry Bankert]

Getting this error I'm assuming it has to do with the Railo video extension, I had only installed it at one juncture to play around this is my dev server, but how can I manually remove the extension thanks

Does that info belong in the migration docs? Is is this just a transient phase until that gets fixed in the available downloads?

I was able to figure out where it was pulling it from, I just didn't to go about deleting things without some kind of guidance. Anyway I found the file at issue located in
Railo Root/lib/lucee-server\context\lib\railo-videoconverter.jar  I believe that was the file stopped lucee removed the jar and things fired up just fine.

[Julian Halliwell]

Micha, could you just clarify the steps and I'll happily update the
migration wiki page?

You need to edit
[railo-install]/lib/lucee-server/context/lucee-server.xml and change

railo.runtime.video.VideoExecuter

to

lucee.runtime.video.VideoExecuter

Is that right?

Sorry but I didn't have that extension in my previous Railo setup.

[David]

Julian, exact those steps solved it for me.

After this change tomcat started up without issues.

Thanks for confirming, David. I've updated the wiki:

i did some digging and to be honest my previous mail was/is not really a solution to the Problem.

This just has made that Lucee fails to load the extension entirely.

Before this "fix", Lucee was able to load the class "railo.extension.video.ffmpeg.VideoExecuterImpl", but then java failed to load the interface "railo.runtime.video.VideoExecuter" what is implemented in that case, this failure was not captured, so Lucee failed to start (i just changed that fact for the next release).

So this was not a fix at all!

Problem is, this Extension is not under active development for a long time and it never was released from Railo under an open source license, even I have written the extension, i'm not allowed to change it for Lucee and release is as open source extension?!

So the only way to fix this is to use the existing extension together with the jar attached to this mail.

So the steps to fix the issue are:

1. when you alreay have changed "railo.extension.video.ffmpeg.VideoExecuterImpl" to "lucee.extension.video.ffmpeg.VideoExecuterImpl", change it back to "railo.extension.video.ffmpeg.VideoExecuterImpl"

2. copy the attached jar next to "railo-extension-video.jar"

3. restart Lucee

done

i will publish this info in the wiki

I haven't tested it in a while, but there's this tool too, which does some of the same stuff I think, FWIW:
