Looping through a VO collection

	Hi there! I have a collection of VOs in my request, I'd like to loop 
through it using the <html:logic> and <html:link>
The idea is to create links for a page. But how do I access the properties 
of the VO? Let's suppose I want to build a list of links like this
How do I combine those tags to render such string:

someAction.do?name=VO.getName()&id=VO.getID();

??

Thanks

RE: Looping through a VO collection

Posted by Richard Hightower <rh...@arc-mind.com>.
Classic Struts
	<logic:iterate id="foo" name="bar" property="foos">

		<html:link action="someAction" paramID="id" paramName="foo"
paramProperty="id"><bean:write name="foo" property="name"/></html:link>
	</logic:iterate>

JSTL
	<c:forEach var="foo" collection="${bar.foos}">
		<html:link action="someAction" paramID="id" paramName="foo"
paramProperty="id"><c:out value="${foo.id}"/></html:link>
	</c:forEach>


JSP 2.0
	<c:forEach var="foo" collection="${bar.foos}">
		<html:link action="someAction" paramID="id" paramName="foo"
paramProperty="id">${foo.id}</html:link>
	</c:forEach>


If you want to pass multiple parameters you could do this....

	<logic:iterate id="foo" name="bar" property="foos"
type="org.mycompany.Foo">
		<jsp:useBean id="params" class="java.util.HashMap"/>
		<%
			params.put("name",foo.getName());
			params.put("id",foo.getId());
		%>
		<html:link action="someAction" paramID="id" name="params"><bean:write
name="foo" property="name"/></html:link>
	</logic:iterate>

At this point however, you may be better off using c:url instead of
html:link (to avoid Java scriptlets).
