It has always been plagued by the MySQL driver in Java, for example Program"Class. forname (" com. MySQL. JDBC. Driver "). newinstance?
I started using this operation when I saw someone else on the Internet, but it was always unsuccessful. Later I saw someone using "org. gjt. Mm. MySQL. Driver". I started to focus on "com. MySQL. JDBC. Driver". How does it work? I just defined this name myself. I can also use another name and use "com." in "Database Pilot. mySQL. JDBC. driver "yes, it can be used in JSP page programs, but it cannot be used in JavaBean. Why? Later I decompressed the "mysql-connector-java-3.1.11-bin.jar" I used, and now I understand, "org. gjt. mm. mySQL. driver "is the path Structure of the driver and needs to include" mysql-connector-java-3.1.11-bin.jar "in the package of the released program ", for example, my JSP program is to add "WEB-INF" under "mysql-connector-java-3.1.11-bin.jar/lib" under the program directory ". Therefore, before using MySQL-connector-Java, determine the specific version you are using.
