Subject: Local Forward with Parameters Causes Exception
>
> 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".
