Hi,
I ran into the following problem: I want to specify a local forward that
represents an action URL. The action requires parameters that I want to
pass
in common HTTP fashion, namely
/product.do?action=list&sortBy=date&order=desc
Therefore, I have an entry in struts-confix.xml that looks like this:
<action path="/product"
type="tquas.bogus.servlet.ProductActions"
parameter="action"
name="productForm"
scope="request"
unknown="false"
validate="true">
<forward name="postCreate"
path="/product.do?action=list&sortBy=date&order=desc&count=10"/>
</action>
where ProductActions is a subclass of DispatchAction containing an
implementation of method list().
The problem is that the XML parser throws an exception, basically
telling me
that ampersands are not allowed in this URI:
org.xml.sax.SAXParseException: Next character must be ";" terminating
reference to entity "sortBy".

This kind of puzzled me, but I obeyed and replaced the ampersands with
semicolons. Now the parser shuts up, but as soon as I hit the specified
forward, struts seems to hang in a loop until it produces a
StackOverflowError
(details see below).
Can anybody help me with this and tell me how I specifiy a local forward
that
accepts parameters in the URI?
Thanks in advance, tom
