Unable to start JRI with tomcat 10

[SpyOO]

I get a error when install into tomcat 10 the version 2.7 of JRI

# java -version

Java(TM) SE Runtime Environment (build 16.0.1.0.1+1-2)
Java HotSpot(TM) 64-Bit Server VM (build 16.0.1.0.1+1-2, mixed mode, sharing)

after deploy jri I get the error in catalina.out file :

I got the same error with JDK 17 and Tomcat 10, I also got this message

21-Dec-2021 10:11:42.894 SEVERE [main] org.apache.catalina.core.StandardContext.listenerStart Error configuring application listener of class [de.oc.integration.jasper.webapp.AppServletContextListener]

I found that it is because the javax Package has been renamed to jakarta , so, we have to install Tomcat 9. https://stackoverflow.com/a/64418685

Yeah, this is kinda difficult.

When I upgrade the existing code, it will work with Tomcat 10 ... AND break on Tomcat 9.

I need to find an easy way to build both versions ... but there are many places in the code to change. There is this automatic migration tool: https://tomcat.apache.org/migration-10.html#Specification_APIs

Not sure, that I can use that to build both versions.

But perhaps using Tomcat9 will be fine for now?

I have decided to continue developing for Tomcat9.

In addition to that, I will use the migration tool to BUILD an additional war file for Tomcat10 only. This will be added to the binary downloads.

For that conversion I will use the official Tomcat migration tool: https://tomcat.apache.org/download-migration.cgi
