Answer 1

Hi,
The JAG does not currently support this feature for JSP's, but it is quite easy to add this functionality post-generation.
Here are the steps, illustrating how to set up a range query using employee sal:
In the Find JSP page:
1. Rename the property FindEmployeeSal to FindEmployeeSalFrom.
2. Add another form field based on property FindEmployeeSalTo.
Here is example snippet of your find JSP page after you have applied steps 1 and 2 (changes in bold):
<tr>
<td class="prompt" nowrap="nowrap">Sal between</td>
<td nowrap="nowrap">
<html:text name="FindEmployee" property="FindEmployeeSalFrom" size="7" maxlength="7"/>
and
<html:text name="FindEmployee" property="FindEmployeeSalTo" size="7" maxlength="7"/>
</td>
</tr>
In the Struts-config, go the the definition of the FindEmployee form bean:
3. Rename property FindEmployeeSal to FindEmployeeSalFrom
4. Add property queryOperator with value "gt" (greater than) to FindEmployeeSalFrom
5. Add new form bean property FindEmployeeSalFrom, set the persistentAttribute to "Sal" and the queryOperator to "lt" (lower than).
Here is the snippet of your from bean after you have applied steps 3 to 5 (changes in bold):
<form-property className="oracle.jheadstart.controller.struts.config.JhsFormPropertyConfig" name="FindEmployeeSalFrom" type="java.lang.String">
<set-property property="persistentAttribute" value="Sal"/>
<set-property property="queryOperator" value="gt"/>
</form-property>
<form-property className="oracle.jheadstart.controller.struts.config.JhsFormPropertyConfig" name="FindEmployeeSalTo" type="java.lang.String">
<set-property property="persistentAttribute" value="Sal"/>
<set-property property="queryOperator" value="lt"/>
</form-property>
That's all!
