RE: trouble passing multiple parameters using html:link
For the relatively low cost of specifying your servlet mapping, you
can use the JSTL c:url/c:param tags and achieve all of this much more
concisely:
c:url var=myUrl value=/partDetailView.do
c:param name=storeNo value=${stockingStoreSalesReviewForm.storeNumber} /
c:param name=storeName value=${stockingStoreSalesReviewForm.storeName} /
/c:url
a href=c:out value=${myUrl} /Click Here/a
There's an enhancement request filed to add c:param type
functionality to html:link, and I think I even assigned it to
myself, but to be honest, I am satisfied with the JSTL alternative
and haven't had (and don't expect to have) time to add an
html:param tag to the Struts JSTL just for the general good.
All that html:link provides in the specific case below is a lookup
function which (a) verifies that you have a valid action path at JSP
compile time and (b) gives you the freedom to change your mappings
from *.do to *.foo or anything else -- a freedom which is
probably compromised in most apps by the need to have external links
into the application, so which doesn't seem all that valuable to me.

You want to specify the Map under the attribute name, not paramName, so:
html:link action=/partDetailView name=storeInfo
scope=pageClick Here/html:link

But you give at the Action a java.util.HashMap not a String and its name is storeInfo not storeNo. am I mistaking? Roberto ___ Yahoo!

Are you sure stockingStoreSalesReviewForm.getStoreNumber() is returning valid data? L.

RE: trouble passing multiple parameters using html:link
Try it step by step. Before passing a map, pass the values hardcoded: html:link action=/partDetailView?storeNo=123storeName=TheStoreClick Here/html:link And make sure that works. If it does, put storeNo and storeName into the storeInfo bean (you dont have to use scriptlets): jsp:useBean id=storeInfo class=java.util.HashMap c:set target=storeInfo property=storeNo value=123 / c:set target=storeInfo property=storeName value=TheStore / And test again (I probably have an error somewhere so make sure to check the syntax).
