source works - design doesnt (jbuilder)

[otto stepper]

hoping very much to get this step done with one of yours knowhow:
using javasourcecode (in JBuilder) :
conn=DriverManager.getConnection("jdbc:mysql://192.168.xx.xx:3306/alben","","")
works fine, I get connected and I can create SQL-Statements successfully...
using JBuilders-Design-Tag and Creating there a Database und trying to create a connection
out of its Connection-dialog
Driver:sun.jdbc.odbc.JdbcOdbcDriver
URL: jdbc:mysql://192.168.xx.xx:3306/alben
results in an Error:
The URL could not be found. Check the correct writing and if the correct
Driver exists within the classpath...
What must be done in which way to get the correct Driver mounted to the JBuilder-(Design-Tab)?
regards otto
