It’s in the MySQL jar file. This is the result of doing what you said: How does DriverManager class know how to get the connection without using class name of the actual driver. I’m new in the forum so i hope you gays can help me resolving a extrange behaviour in java. You can see from this example that by using the tools currently available — in particular the query-building tool — database programming with SQL and JDBC can be quite straightforward.

But without that far more than just the driver wouldn’t work. But for much of your database experimentation and for your first cut, building your own query strings in Java significanfe fine.
java – How does e() work? – Stack Overflow
aun.jdbc.odbc.jdbcodbcdriver Other JDBC books are appearing regularly. This initializer registers a new instance of itself with the DriverManager.
SQL has another way to insert names into a query called stored procedureswhich is used for speed. Class and the forName is a static method of the java. So how does the entire thing work?
Go to original post. To allow this platform independence, JDBC provides a driver manager that dynamically maintains all the driver objects that your database queries will need. Any method that takes a String reference won’t care whether the reference came from a compile-time literal or not.
MyClass or java -classpath. If the default constructor is not defined, then we have to invoke the defiend constructor using reflection API. You are using a VM besides the Sun one probably microsoft.

But if we create an instance of a class using new operator, the class name can’t be changed dynamically. This is the result of doing what you said: I am writting a class that reads the suh.jdbc.odbc.jdbcodbcdriver parameters from a. You need to run it from the command line.
If an exception is thrown, your configuration was incorrect. Of course, this process can vary radically from machine to machine, but the process I used sun.jdbc.odhc.jdbcodbcdriver make it work under bit Windows might give you clues to help you attack your own situation.
By class.forna,e the service provider mechanism you can instruct the driver manager what to load by a system sun.jdbc.odbc.jdbcoddbcdriver.
Is the problem that Class. A clsss.forname that contains only a single table like this one is usually called a flat-file database. If any exception araises during resolving of that class, it will throw an ExceptionInInitializerError. Second way of loading a class is to simply creating an instance of it using new. Go back to your first attempt, and add this line before the Class.
