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\Java\ jdk-10.0.1

---

echo %JRE_HOME%

C:\Program Files\Java\ jre-10.0.1

---

OS : Windows 8 64-bit

---

Eclipse Version: Oxygen.3a Release (4.7.3a)

---

Whenever I run catlina.bat start from cmd, server runs fine on localhost But I'm not able to get the server instance up from eclipse's server configuration.

1. Defined a new server in eclipse and added apache-tomact 9.0 instance

2. Upon clicking on start server , I get the following error:

   -Djava.endorsed.dirs=C:\Softwares\apache-tomcat-9.0.7\endorsed is not supported. Endorsed standards and standalone APIs in modular form will be supported via the concept of upgradeable modules.

Any solution for this issue ?

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! :)
