Hello Romina,

Can you give us the full error that is being displayed?

Also, what version of Tomcat are you specifically trying to use? Not all of them are properly supported.

Please refer to our Supported Technologies page to see what versions of software are supported with LabKey here.

Thanks Romina,

Just curious, is your version of Tomcat directly downloaded from Apache's website or did you use a package manager to get it? Sometimes connections get weird when you use a package manager version.

Also, is there any chance you can use a more recent version of Tomcat as well? We support 7.0.72 and 8.0.38.

Regards,

Jon
