Hi all! Is there anyone to know what cause this error message.
I followed all instruction from INSTALL precisely but at the step when I should start the index server I got problems. Please, help!

java -cp C:\Alek\work\OpenSource\ladon\classes;C:\Alek\work\OpenSource\ladon\lib\mysql2.jar org.ladon.indexserver.IndexServer jdbc:mysql://localhost:3306/ladon?user=server
