I've just upgraded the 2nd system which is not running just fine. I've been
working
on this for a week. When I run it I get numerous errors related to "source level
is 1.5 or greater."
when I run tomcat I get:
Using CATALINA_HOME: /srv/tomcat
Using CATALINA_TMPDIR: /srv/tomcat/temp
Using JRE_HOME: /user/util/src/jdk-17.0.8
Using CLASSPATH:
/srv/tomcat/bin/bootstrap.jar:/srv/tomcat/bin/tomcat-juli.jar
The libs on the non-running system are basically the same as on the running
system except some are newer versions. I can post the differences if that would
help.
I've compared the $CATALINA_HOME/conf files between systems and I don't see any
meaningful differences.
I've tried changing https://jakarta.ee/xml/ns/jakartaee/web-app_6_0.xsd to
https://jakarta.ee/xml/ns/jakartaee/web-app_5_0.xsd (which is one difference).
That didn't help.
I've tried explicitly setting the compilerSourceVM to 11. That didn't help.
What can I look at to find this problem and fix it?
Please clear out the logs, start the Tomcat instance then provide
complete error message(s) including any stack traces you get on the
console / in the logs / in the browser and tell us where you see them.
If there are lots of errors, the first ones are very likely to be the
most useful.
