I am running core 3, and trying to execute the following commend: [root@kt fileIndexer]# java -Xmx256m -jar FileIndexer-1.1.4.jar Upon doing so, I get the following error: java.sql.SQLException: Invalid authorization specification message from server: "Access denied for user: 'root@xxxxxxxxxxx' (Using password: YES)" at com.mysql.jdbc.MysqlIO.checkErrorPacket(MysqlIO.java:1997) at com.mysql.jdbc.MysqlIO.checkErrorPacket(MysqlIO.java:1906) at com.mysql.jdbc.MysqlIO.doHandshake(MysqlIO.java:954) at com.mysql.jdbc.Connection.createNewIO(Connection.java:1786) at com.mysql.jdbc.Connection.<init>(Connection.java:450) at com.mysql.jdbc.NonRegisteringDriver.connect (NonRegisteringDriver.java , etc .......... I have looked around on google and some think it may be an issue about plain text passwords vs md5. when running the command there is not a way to provide credentials, so I am not sure why it says I am using a pasword. I also found a posting that someone felt it had to do with using a tcp connection rather than localhost. Not sure how to get it to work. Any ideas?
