Hi,
I got everything working now after a few hours investigation.
The motivation was to get a basic setup working within a portlet AND a
servlet environment with a simple implemented service layer in context
of JSF.
The promised simplicity of iBatis seemed to be ideal for the
requirements: getting a loosly coupled DAO service, model undriven and
flexible in configuration, extensibility and usage. The excellent SPRING
support was not least the key between everything.
Therefore a small summerize at this point how to glue JSF with Spring
and iBatis.
Some links helped me:

http://svn.apache.org/repos/asf/ibatis/trunk/java/ibatis-2/ibatis-2-docs/en/iBATIS-SqlMaps-2_en.pdf
The configuration based on facelets 1.1.14, myfaces 1.1.6, ibatis
2.3.4.726, spring-framework 2.5.5 (spring.jar, spring-webmvc.jar,
spring-webmvc-portlet.jar), the portal environment is liferay x.
Only the relevant fragments are listed below portal type is independent.
The approach was to simply call a db sequence as a first step, no
classes of properties or resultsets mapped here. (shouldn't be a problem
anymore)
Kind regards,
Andreas
