Custom Data Transfer in WSRP Interceptor Framework

Question

Hi,
I'm trying to pass custom data (XML data) between the consumer and producer(WLP 10.3) in Interceptor Framework.
This is what I'm trying to do:
public Status.PreInvoke preInvoke(IGetMarkupRequestContext requestContext) {
root = (Element) document.createElement("Test1");
document.appendChild(root);
root.appendChild(document.createTextNode("111"));
xp = new XmlPayload(root);
requestContext.setMarkupRequestState(xp);
What if I want to send another XML data "Test2"? Any pointers will be helpful?
Thanks.

Hello,
The WSRP custom data transfer implementation allows only a single XML root element to be sent as the custom data, but that root custom data element can contain as many child elements as you want. So you could do it something like this:
Element root = (Element)document.createElement("CustomData");
// Add first bit of custom data
Element test1 = (Element) document.createElement("Test1");
root.appendChild(test1);
test1.appendChild(document.createTextNode("111"));
// Add second bit of custom data
Element test2 = (Element) document.createElement("Test2");
root.appendChild(test2);
test2.appendChild(document.createTextNode("222"));
XmlPayload xp = new XmlPayload(root);
requestContext.setMarkupRequestState(xp);Kevin
