Can't get embedded driver from eclipse

Question

I'm trying to run application working with derby database. I've installed derby. Added jars to classpath and to build path of eclipse. I'm working with this guide. When I run sample app it starts and finishes successfully. But when I use in my program:

Class.forName("org.apache.derby.jdbc.EmbeddedDriver").newInstance();

It says:

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

Though it works fine at sample. I'm stuck. Need help. my classpath:

/opt/Apache/db-derby-10.10.1.1-bin/lib/derby.jar:/opt/Apache/db-derby-10.10.1.1-bin/lib/derbytools.jar: Full stack trace
