I am getting ORA-29532: Java call terminated by uncaught Java exception: javax.net.ssl.SSLHandshakeException: Received fatal alert: handshake_failure exception when I try to run java class from PL SQL. Some URL works fine, but most get this error.When I run this class from IntelliJ every kind of URL works fine. Can anyone please direct me where the problem could be?
