Migrating to Tomcat 9.0 for Liferay 7.0

[David Choi，修改在6 年前。]

Hello I was wondering if it is possible to migrate Liferay 7.0 from tomcat 8.0 to tomcat 9.0. I ran into errors when trying to run Liferay 7.0 by placing .

I get a:

SEVERE [main] org.apache.catalina.core.StandardContext.listenerStart Exception sending context initialized event to listener instance of class com.liferay.portal.spring.context.PortalContextLoaderListener
java.lang.ExceptionInInitializerError

and I'm not sure what is the problem. I was wondering if anyone had experience migrating to tomcat 9.0.

Tomcat 9 is currently not supported. Unfortunately that means that any errors you encounter will be yours to resolve...

If you do fix them, though, posting solutions back here I'm sure would help others.

So I was able to get it to work on tomcat 9.0 by following the instructions at this link:

I think it was primarily a matter of configuration.
