The structuredStatements property of the StructuredQueryFormHandler is an array of StructuredStatement objects. When the form handler submits a query, it uses each object in the array to create a separate <statement> tag for the query. The attributes of the tag are set from the properties of the StructuredStatement object.
In the JSP, you create the individual StructuredStatement objects by setting the properties of each object through form fields. For example, the following page fragment creates a four-row table where each row represents an individual <statement> tag:
<c:set var="formHandlerPath"
value="/atg/search/query/formhandlers/SampleStructQueryFormHandler"/>
<c:set var="tagname" value="structquery"/>
<dspel:importbean var="formHandler"
bean="${formHandlerPath}"/>
