Flow:
HTTP Input -> ESQL Node -> (trace) -> Java Compute Node
ESQL Code:
| Code: |
DECLARE ns NAMESPACE 'http://RPlus.org/VCompUpdate.xsd';
CREATE COMPUTE MODULE R_V_Compute
CREATE FUNCTION Main() RETURNS BOOLEAN
BEGIN
CALL CopyMessageHeaders();
-- Output is MQ, so remove HTTP headers
SET OutputRoot.HTTPInputHeader = null;
-- Output is legacy, so set wire format and message name
--SET OutputRoot.Properties.MessageType = 'VCompUpdate';
--SET OutputRoot.Properties.MessageFormat = 'XML1';
-- Add an MQMD, and restore from the original MQInput
CREATE NEXTSIBLING OF OutputRoot.Properties DOMAIN 'XMLNSC';
--SET OutputRoot.XMLNSC = InputRoot.XMLNSC;
SET OutputRoot.XMLNSC = InputRoot.XMLNSC;
RETURN TRUE;
END;
CREATE PROCEDURE CopyMessageHeaders() BEGIN
DECLARE I INTEGER 1;
DECLARE J INTEGER;
SET J = CARDINALITY(InputRoot.*[]);
WHILE I < J DO
SET OutputRoot.*[I] = InputRoot.*[I];
SET I = I + 1;
END WHILE;
END;
CREATE PROCEDURE CopyEntireMessage() BEGIN
SET OutputRoot = InputRoot;
END;
END MODULE;
|
Part of the Java Code:
| Code: |
// optionally copy message headers
copyMessageHeaders(inMessage, outMessage);
// ----------------------------------------------------------
// Add user code below
MbElement outRoot = outAssembly.getMessage().getRootElement();
MbElement outBody = outRoot.getLastChild().getFirstChild();
String xmlDoc = (String)outBody.getValue();
|
Now I am sending a XML Doc to the HTTP Input
Now i see the data deep in the trace but I just can't fins a way that will allow me to access it.
Trace:

You're really confused about what
| Code: |
| String xmlDoc = (String)outBody.getValue(); |
means.
This isn't even a confusion about ESQL versus Java, it's a confusion about parsers and logical message trees.
Please re-visit your Broker training material.

I have passed message between nodes before using the save java code and it has never given me a problem, but this time it is.
Any specific place i should look for this infomation? |

I also tried XPath and to get all elments of the and it just return properties of the msg
| Code: |
MbMessage msg = outAssembly.getMessage();
List chapters = (List)msg.evaluateXPath("//*");

You certainly did not CopyEntireMessage by using .getValue() on the XMLNSC element followed by setValue().
Again, you appear to be very confused about what a logical message tree is, and what it consists of.
This is fundamental to using Broker, and fundamental to even using ESQL. It's the difference between
| Code: |
| Set OutputRoot.XMLNSC = InputRoot.XMLNSC |
and
| Code: |
| Set OutputRoot.XMLNSC Value= FIELDVALUE(InputRoot.XMLNSC) |
Please review your Broker training material.
