Javax error after upgrading to MacBook with M4

[ben.ralph.nmc]

Hi All

I've recently switch to a new MacBook Air M4 and I'm having a problem getting the import utility working. Everything else is working fine and I can publish from Protege to the essential viewer website. Below is the error I'm receiving when I try to access the website.

If it helps...I installed tomcat and java using homebrew. Initially i installed the latest version of java and subsequently installed java 8 using homebrew, which required me to install rosetta 2 before I could install java 8. When i run 'java -version' it says I'm running 24.0.1 however, homebrew shows that temurin@8 is installed. I have tried to run the 'jdk-8u202-macosx-x64' installer package but it fails to install.

Any help would be much appreciated.

Thanks

Ben

Apache Tomcat/9.0.105

Given the JAXB error, I suspect that either JVM or Tomcat version is missing a library. I can't think of a solution to that right now.

Have you tried using the Essential Standalone version? That contains an embedded JVM and certainly the Import Utility should work there.

Hi Neil

Thanks for your response and you were correct. I needed to copy JAXB and istack jar files to the tomcat lib folder.

All working perfectly now.
