Apache Derby - Database created but not found

问题

This is in continuation to my previous question

I'm trying to embed a derby database in my web application. I'm able to embed it, though I am facing glitches. Here's the snapshot of my project structure.

I wonder why class.forName("org.apache.derby.jdbc.EmbededDriver") is throwing exception?

java.lang.ClassNotFoundException: org.apache.derby.jdbc.EmbededDriver

To overcome this, I have used

DriverManager.registerDriver(new org.apache.derby.jdbc.EmbeddedDriver());

Which works well. Why is it so? Also, Where would it create database if coded like this. I cannot spot the database.

connection = DriverManager.getConnection("jdbc:derby:MyDbTest;create=true");

I checked in tomcat webapps and eclipse workspace, I didn't find database.

If given this way, I can spot it.

connection = DriverManager.getConnection("jdbc:derby:E:/MyDbTest;create=true");

回答1:

class.forName("org.apache.derby.jdbc.EmbededDriver")

Threw an exception because there is a 'd' missing from embedded.

See here for information about specifying the location of databases on the file system.
