Java error when using admin console or packaging

Question

Hello together,
I am trying to install the Content Server on a Windows Server 2003.
I am using the Quick  guide and so far everything worked out fine.
MySQL tables were created, I have a nice p12-file, and all the three  "statuscheck"-pages were 100% ok.
But the problem is, I can not log in to the administration console and  can not start the packaging command.
In both cases the program acts like it would not recognize the password  (I still have to use the default password "park345"). But when I looked  at the error log, it seems more like an  internal problem with a string conversion when the script tries to read  the data of the default distributor from the mySQ database.
11 Jan 2011 15:26:41,701 TRACE DefaultSQLDatabaseConnection: SELECT  distid, name, description, disturl, notifyurl, publickey, sharedsecret,  maxloancount, linkexpiration FROM distributor WHERE distributor.distid = ?
11 Jan 2011 15:26:41,701 TRACE DefaultSQLDatabaseConnection:   obj 1 =  [B@716cb7
11 Jan 2011 15:26:41,701 TRACE DefaultSQLDatabaseConnection: rollback
11 Jan 2011 15:26:41,717 ERROR AdeptServlet: internal error [87.234.61.82]
java.lang.ClassCastException: java.lang.String cannot be cast to [B
What can I do?
Does anyone knows what I have to change or what went wrong? Is this a mySQL-problem?
I am a little lost here. :-(
Greetings!
Ralf

Answer 1

I now found the solution myself.
For everyone who stumbles upon the same problem:
The problem was the Java-mySQL-Connector!!!
For some reason, I downloaded the version 3 of the connector.
I now tried the version 5 and now everything works!
