apache tomcat 9.x not working with eclipse & Java 10.0.1

Question

I\'ve installed apache-tomcat-9.0.7 on my windows machine and have following environment configurations:

echo %JAVA_HOME%

C:\\Program Files

Answer 1

In my Eclipse Oxygen IDE, WTP version did not update as suggested by @nitind.

I figured out a fix with some trial and error as I wanted to change JRE version for Tomcat

1. To use Tomcat 8 with JRE 8 Eclispe --> Preferences --> Server --> Runtime Environments --> Select Tomcat 8 --> Edit --> Change default JRE to JRE 8

Also change JDK version in Compiler & Project Facets

2. Eclispe --> Preferences --> Server --> Runtime Environments --> Select Tomcat 9 --> Edit --> Change default JRE to JRE 9

Also change JDK version to 9 in Compiler & Project Facets

Also need to remove -Djava.endorsed argument from "Runtime Configurations" in Project right click --> Run As --> Run Configurations --> Apache Tomcat

It will surely work! :)
