Message: [QUOTE="Robert Klemme, post: 4219443"] If Class.forName() is the bottleneck then a static factory method does not help in this particular case. You would have to configure the method name or a class name anyway and use reflection to get at the instance or method. Abu, to answer your question (pseudo code): interface com.your.company.db.DbManager { // methods } interface com.your.company.db.DbManagerFactory { DbManager create(/* args if needed */) throws WhateverException } class com.your.company.db.ora.OraDbManager implements DbManager { // ... } class com.your.company.db.ora.OracleDbManagerFactory implements DbManagerFactory { public DbManager create() { return new OraDbManager(); } } Kind regards robert [/QUOTE]
