Hello,

We got the following exception saving an object with an enum :

"
java.lang.AbstractMethodError: com.microsoft.jdbc.base.BasePreparedStatement.getParameterMetaData()Ljava/sql/ParameterMetaData;
at org.hibernate.type.EnumType.guessTypeByParameter(EnumType.java:200)
"

I've tried changing the type of the column from int to string, doesn't change anything.

Some help/ideas ?

MS Server 2000
jdbc driver from Microsoft (pack 3).
Dialect = "org.hibernate.dialect.SQLServerDialect", Driver = "com.microsoft.jdbc.sqlserver.SQLServerDriver", URL = "jdbc:microsoft:sqlserver://....;

It's working fine with JTDI drivers the latests http://jtds.sourceforge.net/

Try the latest MS driver (in beta if I remember).
And report the bug to the MS team.
