http://localhost:8080/pvws 404NotFound

[zhuzzzzzz]

After I deployed the pvws.war package in /webapps/ , it creates a /pvws/ dirctory
But I still cannot access http://localhost:8080/pvws, it suggests 404NotFound.

I tried to look at the log and found this, so what happened and what should I do?

What's your tomcat version? If it's 10 or higher, see #13

[zhuzzzzzz]

it is 8.5.87

Tomcat 7 and 9 work fine, so I assume 8 is good as well.

Are you compiling from sources as described in https://github.com/ornl-epics/pvws#building, and then running Tomcat with the same JDK that was used to compile?
Or are you using some binary?
If you're using the "nightly" binary, that's currently built with JDK 15. So if you then try to use that with Tomcat running JDK 11..14, you'll get class file version errors, should see that in the more detailed log.

==> Use at least JDK 15 with the binary, or (preferably) built it yourself.

It works, Thanks very much
I think it is just the matter of jdk version. I can not successfully bulid the project or run the binary file in tomcat under jdk11 but in jdk17 both of them works.
