Subject RE: No valid JdbcConnection class available with MySQL
Date Mon, 02 Jun 2003 01:19:54 GMT
Are the samples still in tact (I assume they are since this 
is binary dist)?  If so, can you confirm that the database 
samples (which use hsql) are working, or do you get the 
same error?  If so, I'd guess that you may be using a 
jdk 1.2/3 version of the excalibur database package.  

Do a directory listing of your WEB-INF/lib - any jdk dependant 
jars should give some clue as to which version they are.
