Hello
We want to run runtimeconfig app exported from OD 7.2.1 on a tomcat with java 1.7.
we get the error: unsupported major.minor version 51.0 while trying to access runtimeconfig app.

Is it possible to run runtimeconfig app exported from OD 7.2.1 on a tomcat with java 1.7? or do we have to use java 1.8 on tomcat?

regards

This error actually means you are running a lower Java version than 1.7.
Version 51 is 1.7 which runtimeconfig is compiled with.
Check your Tomcat settings

Hello
Actually there are two tomcat versions running with different java versions on that same machine.
The tomcat I am running this runtimeconfig on, is using Java 7. No problems with that.
The other tomcat uses java 6 which is the default java on that machine. (java -version response)
May the runtimeconfig app be using the default java instead of the java 7 which is the version the tomcat uses the runtime config is running on?
Regards

It depends on how you configure and start the Tomcat instance. I can't tell you exactly since every environment is different.
