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.

Error Screen

Any solution for this issue ?

You need an update that isn't on the main Oxygen site. Add http://download.eclipse.org/webtools/repository/oxygen/ as a URL in your Available Software Sites preference page and then check for updates from the Help menu.

https://bugs.eclipse.org/533162

Edit: this fix will be properly included in the Photon (WTP 3.10) release later this month.

    kudos to you @nitind !! Issue is resolved upon installing WTP 3.9.4 – Saurabh Bhoomkar Apr 30 '18 at 14:16
  • This almost worked for me. For some reason, Oxygen would not auto detect the new WTP version and insisted that there was nothing new to install. I had to go through the install new software help flow to get 3.9.4. Thanks a lot nitind and @Saurabh Bhoomkar. – zerpsed May 14 '18 at 19:51
  • Same Problem. Could you let me know how to install WTP 3.9.4 @zerpsed – Teja Jun 26 '18 at 16:59
  • @Teja are you **sure** that site is in your list of update sites? – nitind Jun 26 '18 at 17:11
  • Could you please help me with this issue? I have been trying this from yesterday onwards.. – Teja Jun 26 '18 at 17:18
  • I have already installed it and can see it in my eclipse market place. – Teja Jun 26 '18 at 17:28
  • @Teja this isn't available through the Marketplace. – nitind Jun 26 '18 at 17:39
  • Yes, now WTP 3.9.4 got detected and I installed on my machine. And my problem is still unresolved that, I could not start my Tomcat 8 server. It's throwing me the same error. – Teja Jun 26 '18 at 17:58
  • Does the Console view indicate an error about an endorsed libraries parameter no longer being supported? – nitind Jun 26 '18 at 19:52
  • @Teja, just saw your comment to me, looks like you got 3.9.4 installed now. After getting things in good shape, I had a few subsequent problems with wtp but not Java 10 related. – zerpsed Jun 27 '18 at 13:22
  • Thank You @nitind My issue got resolved with Photon update – Teja Jun 27 '18 at 20:38

I had to remove that argument from the launch configuration:

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

  1. 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! :)

Removing -Djava.endorsed.dirs="C:\Program Files\Apache Software Foundation\Tomcat 9.0\endorsed" from server config worked for me also
