I don't think there's a specific "Roo" way of doing this, but Spring MVC does have an AbstractExcelView class that uses Apache POI and doesn't cause any problems - I think it's the best you can hope for. First create a view class that extends AbstractExcelView and implements the buildExcelDocument method: <pre><code> import org.springframework.web.servlet.view.document.AbstractExcelView; public class XlsView extends AbstractExcelView { @Override protected void buildExcelDocument( Map<String, Object> model, HSSFWorkbook workbook, HttpServletRequest request, HttpServletResponse response) throws Exception { //Apache POI code to set up the HSSFWorkbook goes here response.setHeader("Content-Disposition", "attachment; filename=\"file.xls\""); } } </code></pre> Then add the following to your webmvc-config.xml. I don't think the position matters, but I have it below the section where my TilesConfigurer is listed: <pre><code> <bean id="excelViewResolver" class="org.springframework.web.servlet.view.XmlViewResolver"> <property name="order" value="1"/> <property name="location" value="/WEB-INF/views/views-excel.xml"/> </bean> </code></pre> Finally create views-excel.xml with the following in it: <pre><code> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd"> <bean name="XlsView" class="com.your.package.XlsView"/> </beans> </code></pre>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
