Java - com.mysql.jdbc.Driver

[arkham19]

Dear all,

Today I tried to access on my site (http://arkham19.heliohost.org/mb/), but unfortunately I've got an error:

 

Error report: [Home]

Could not initialize class com.mysql.jdbc.Driver

It 's very strange because I have not uploaded code updates and few days ago I could easily access to my site.

I also tried to access the database from my local site with Eclipse and it work well.

 

Can you give me assistance, please?

Thanks in advance!
