http://www.trifork.com/package/eos/external/static/T4/doc-4.1/documentation/userdoc/html/ch32.html overriding the important access points such as all access(es) by implementing your own override of JDBCSecurityRealm to (possibly your own base class) underlying principal javax.security.Principal so when your own JDBCSecurityRealm authenticates the supplied username/password via the method public Principal authenticate(String userName, String password) throws LoginException { your catch clause for 'LoginException' would write to Log4j..
