Hi Anthony and thanks for your answer, I am trying out the first way you have suggested, which is the easier for me to understand :-) , however I have several errors com/mysql/jdbc/ServerPreparedStatement.java: In class 'com.mysql.jdbc.Connection': com/mysql/jdbc/ServerPreparedStatement.java: In method 'com.mysql.jdbc.Connection.execSQL(com.mysql.jdbc.Statement,java.lang.String,int,com.mysql.jdbc.Buffer,int,int,boolean,boolean,java.lang.String,boolean,byte)': com/mysql/jdbc/ServerPreparedStatement.java:2323: error: verification error at PC=636 com/mysql/jdbc/ServerPreparedStatement.java:2323: error: might transfer control into subroutine com/mysql/jdbc/ServerPreparedStatement.java: In class 'com.mysql.jdbc.ServerPreparedStatement': com/mysql/jdbc/ServerPreparedStatement.java: In method 'com.mysql.jdbc.ServerPreparedStatement.executeBatch()': com/mysql/jdbc/ServerPreparedStatement.java:713: error: verification error at PC=521 com/mysql/jdbc/ServerPreparedStatement.java:713: error: might transfer control into subroutine com/mysql/jdbc/log/Log4JLogger.java: In class 'com.mysql.jdbc.log.Log4JLogger': com/mysql/jdbc/log/Log4JLogger.java: In constructor '(java.lang.String)': com/mysql/jdbc/log/Log4JLogger.java:41: error: cannot find file for class org.apache.log4j.Logger com/mysql/jdbc/log/Log4JLogger.java:42: error: cannot find file for class org.apache.log4j.Logger com/mysql/jdbc/log/Log4JLogger.java:42: confused by earlier errors, bailing out By the way I've tried out 3; it doesn't seem to work, however I'm giving it a try again.
