Hi Sami,
How you display the results on your JSP depends on what technology you use.
I normally use Jakarta tag libraries
(http://struts.apache.org/userGuide/index.html).
For example:
<logic:iterate id="painting" name="ptgList">
<bean:write name="painting" property="toArtist.name"/>
</logic:iterate>

>Just subclass the bean I have have attached: provided for example:

>{
> /**

> public ComplexList (List pList)

>Usage:

> List lst = mContext.performQuery(qry);

> ComplexList cpxList = new ComplexList (lst, pPageSize, pCurrentRow);
