Cannot start jbpm on http://localhost:8080/business-central

Question

I am a student trying to learn jbpm. Teacher wont help me, so this is my only hope.

I have installed java 13. Server starts, but with some errors. after i type " http://localhost:8080/business-central " i get a error 404. Here is only the error (last) part of the log since the whole thing has more than 40 000 characters, and im allowed only 30 000 here:

1. Please follow the following instructions on the link below.
2. Use H2 Database.
3. Please create environmental variable JAVA_HOME=C:\Program Files\AdoptOpenJDK\jdk-8.0.202.08 and PATH=%JAVA_HOME%\bin (Use Java 8)
4. Please insert the following entries to standalone-full.xml under JBoss_EAP_Home\standalone\configuration

 <system-properties> <property name="org.kie.example" value="true"/> <property name="org.jbpm.designer.perspective" value="full"/> <property name="designerdataobjects" value="false"/> <property name="org.kie.workbench.profile" value="FORCE_FULL"/> <property name="org.kie.server.location" value="http://localhost:8080/kie-server/services/rest/server"/> <property name="org.kie.server.controller" value="http://localhost:8080/business-central/rest/controller"/> <property name="org.kie.server.controller.user" value="<username>"/> <property name="org.kie.server.controller.pwd" value="<password>"/> <property name="org.kie.server.user" value="<username>"/> <property name="org.kie.server.pwd" value="<password>"/> <property name="org.kie.server.id" value="default-kieserver"/> <property name="org.kie.server.persistence.ds" value="java:jboss/datasources/ExampleDS"/> <property name="org.kie.server.persistence.dialect" value="org.hibernate.dialect.H2Dialect"/> </system-properties>

This must resolve the issue.
