Oracle SQL Developer Problem initializing Welcome Page

Question

I installed the Oracle Sql developer but I am not getting the startup page. A JavaFx error is encountered.

How can I solve this problem?

Answer 1

Just FYI, seems the JDK installed with 18.4 XE does not include JavaFX.

[oracle@localhost ~]$ which java
/opt/oracle/product/18c/dbhomeXE/jdk/bin/java
[oracle@localhost ~]$ java -version
java version "1.8.0_171"
Java(TM) SE Runtime Environment (build 1.8.0_171-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.171-b11, mixed mode)
