Hibernate version: 3

Name and version of the database you are using: MySQL 4.1.18


How can I give a query to search for a string in the database dinamically.

eg: "from User as user where user.name like :NAME%"

This throws an deserialization error.

Within your code while you can bind parameters as
Query.setString("NAME", "someName%")

Well I try what you suggested by the following stack trace was shown.
