Tomcat Installation using binaries- endorsed is not supported & error: could not create the JVM

Question

I ve tried to install Tomcat server using binary files in eclipse.When I run cmd and run the startup command, cmd opens and closes and these written on the cmd screen:

>startup

Using CATALINA_BASE:   "C:\Program Files\Tomcat\apache-tomcat-8.5.69"
Using CATALINA_HOME:   "C:\Program Files\Tomcat\apache-tomcat-8.5.69"
Using CATALINA_TMPDIR: "C:\Program Files\Tomcat\apache-tomcat-8.5.69\temp"
Using JRE_HOME:        "C:\Program Files\Java\jdk-15.0.2"
Using CLASSPATH:       "C:\Program Files\Tomcat\apache-tomcat-8.5.69\bin\bootstrap.jar;C:\Program Files\Tomcat\apache-tomcat-8.5.69\bin\tomcat-juli.jar"

(startup.bat also tried but behaves same)

When I run this command:

catalina.bat run

Using CATALINA_BASE:   "C:\Program Files\Tomcat\apache-tomcat-8.5.69"
Using CATALINA_HOME:   "C:\Program Files\Tomcat\apache-tomcat-8.5.69"
Using CATALINA_TMPDIR: "C:\Program Files\Tomcat\apache-tomcat-8.5.69\temp"
Using JRE_HOME:        "C:\Program Files\Java\jdk-15.0.2"
Using CLASSPATH:       "C:\Program Files\Tomcat\apache-tomcat-8.5.69\bin\bootstrap.jar;C:\Program Files\Tomcat\apache-tomcat-8.5.69\bin\tomcat-juli.jar"
-Djava.endorsed.dirs=C:\Program Files\Tomcat\apache-tomcat-8.5.69\endorsed is not supported. Endorsed standards and standalone APIs
in modular form will be supported via the concept of upgradeable modules.
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

>java -version

In the project, JRE setting is like that:

Project -> Properties -> Java Build Path -> Libraries -> JRE System Library -> JavaSE-1.8

Eclipse version is :

>echo %CATALINA_HOME%

C:\Program Files\Tomcat\apache-tomcat-8.5.69

>echo %JAVA_HOME%

%CATALINA_HOME%\bin exists in Path variable.

C:\Program Files\Java\jdk-15.0.2

Does running tomcat with java 8 or using a newer tomcat version work? — dan1st, Jul 25 '21 at 16:54
Check if you don't have a `JAVA_ENDORSED_DIRS` environment variable or an `endorsed` folder in your Tomcat installation. — Piotr P. Karwasz, Jul 25 '21 at 19:02
@dan1st yes, I tried installation with tomcat 8.5.69 and 9.0 but not works, also I am not able to use jdk 8 because my Eclipse version generate issues — Denisa, Jul 25 '21 at 19:44

From catalina.bat source code.

  234 rem Java 9 no longer supports the java.endorsed.dirs
  235 rem system property. Only try to use it if
  236 rem JAVA_ENDORSED_DIRS was explicitly set
  237 rem or CATALINA_HOME/endorsed exists.
  238 set ENDORSED_PROP=ignore.endorsed.dirs
  239 if "%JAVA_ENDORSED_DIRS%" == "" goto noEndorsedVar
  240 set ENDORSED_PROP=java.endorsed.dirs
  241 goto doneEndorsed
  242 :noEndorsedVar
  243 if not exist "%CATALINA_HOME%\endorsed" goto doneEndorsed
  244 set ENDORSED_PROP=java.endorsed.dirs
  245 :doneEndorsed

Also, from the error message it can be seen that the property was passed on tomcat start command line: -Djava.endorsed.dirs= ... so either JAVA_ENDORSED_DIRS env var exists or CATALINA_HOME/endorsed directory exists.

One of the tomcat has endorsed file, and I made changes on settings file. I uninstalled all old versions of Tomcat and install Tomcat 8.5.69 , now [http://localhost:8080](http://localhost:8080) , tomcat web page appears. – Denisa Jul 25 '21 at 21:32
