I am making a configuration in the service parameters of an application to connect to a database SQLServer 2000. When testing the connection generates the following error:

ConnectionService [IG] Encountered unexpected error: DASS_ERROR: 486: Target Connection failure

And when I download from the Microsoft page the JDBC "sqljdbc.jar" for SQLServer 2000 and put it in the path / opt / netiq / idm / apps / tomcat / lib with the necessary permissions. When trying again, I get the following error:

Caused by: com.sun.jersey.api.client.ClientHandlerException: A message
body reader for Java class org.codehaus.jettison.json.JSONObject, and
Java type class org.codehaus.jettison.json.JSONObject, and MIME media
type text / html; charset = utf-8 was not found


Someone has happened to something similar or have some solution that can support me.

Thanks in advance.
