Re: [Fwd: Support for &amp; as a parameter separator in <c:url>]

There is a way to get the escaped ampersand with

c:url and c:out when you set the escapeXml attribute
of c:out to true, it converts the & to &

You will have to "View Source" in your browser to see
the & 

      <c:url var="someURL"
value="http://www.somesite.com/index.jsp" >
          <c:param name="item" value="123" / >
          <c:param name="isbn" value="55555" / >
      < / c:url>

      <c:out value="${someURL}" escapeXml="true" / >

Hope this helps.
