问题
I am at my wits end!
- I have a minimal install of Ubuntu Server 18.04 and OpenJDK 11 (headless).
- Downloaded, to a local folder are the java 9+ binaries for Derby (db-derby-10.15.2.0-bin)
Path and Environment settings are all correct!
When I start the server startNetworkServer -h 0.0.0.0, I get an error when doing a simple connect using the ij command line tool
ij> connect 'jdbc:derby://localhost:1527/dbname;create=true';
ERROR XJ041: DERBY SQL error: ERRORCODE: 40000, SQLSTATE: XJ041, SQLERRMC: Failed to create database 'dbname', see the next exception for details.::SQLSTATE: XBM01::SQLSTATE: XJ001
The derby.log file makes reference to:
java.security.AccessControlException: access denied ("java.lang.RuntimePermission" "getenv.SOURCE_DATE_EPOCH")
Looking further into this error, I learned that I somehow need a security.profile. I found this website that seemed to be the answers to my problems. https://www.javacodegeeks.com/2020/04/apache-derby-database-jvm-security-policy.html
Following these pretty straight-forward instructions, I get:
java.security.AccessControlException: access denied
org.apache.derby.shared.common.security.SystemPermission( "engine", "usederbyinternals" )
