Hi Guys,
I have exposed a message flow to receive the HTTP GET messages.
The data is posted as follows
http://{HostName}/:7080/SubmitOrderSvc?User=XXX?Password=XXX&Payload=%3C%3Fxml%20version%3D%221.0%22%3F%3E...........
I am reading the message as BLOB but not able to decode it back to XML?
Is there any way that we can cast it to XML? 
i used Java Compute Node to decode it back to XML but as ESQL is more efficient i am posting it as a separate thread. x |

CAST is for converting between two simple data types, so is probably not what you need.
Are you asking how to convert a BLOB to a message tree using ESQL?
If so, you need a CREATE statement with PARSE and DOMAIN clauses. There are plenty of examples on the forum. Domain will be XMLNSC, of course. |

You may also be interested to know that from 6.1.0.4 and above the HTTPInput node has a property to parse and url-decode a querystring into name-value pairs in the local environment. This will save you having to parse the querystring by hand. You will still need to use CREATE with PARSE as kimbert suggests to turn the value into an XMLNSC tree through.
Kind Regards,

let me elaborate more on my problem,
Flow:
HTTPInput>>Compute>>HTTP Reply
On the client side the data is posted as following manner.
http://{HostName}/:7080/SubmitOrderSvc?User=XXX?Password=XXX&Payload=%3C%3Fxml%20version%3D%221.0%22%3F%3E...........
there is no case i read the above data except i read it as BLOB domain.
I cast the input message as Char (CCSID 1208) and REPLACE commands to strip out the "User=XXX?Password=XXX&Payload=" to create an XML message.
Then i parse the message using the CREATE PARSE command or using RCD i can parse it...
But in either of the cases it is not getting parsed because the XML message is encoded, is there a broker capability to decode it back to XML? |

Yes, as I said above:

| from 6.1.0.4 and above the HTTPInput node has a property to parse and url-decode a querystring into name-value pairs in the local environment. This will save you having to parse the querystring by hand |
Once you have done this you will have to:
| Quote: |
| parse the message using the CREATE PARSE command |
To turn it into an XML tree.
Use a trace node to look at the LocalEnvrionment after the httpinput node once that option is checked, to see what I mean.
Kind Regards.

HTTPInput>>Compute>>HTTP Reply
I have set Message Domain as "XMLNSC" and Parse Query String checked ..throwing a parser exception
I tried with Message Domain as "BLOB" but no elements created in LocalEnvironment...am i doing something wrong? |

This is done in ESQL

Leave the DOMAIN as BLOB in the HTTP Input node. Check the "Parse Query String" property then look at the tree in a trace node. Use a Compute node to do the CREATE PARSE...

Doesn't work for me.
I have set "BLOB" and checked the option "Parse Query String".
Nothing was created in OutputLocaEnvironment tree.
ESQL:
DECLARE bodyBlob1 BLOB InputRoot.BLOB.BLOB;
DECLARE creationPtr1 REFERENCE TO OutputRoot;
CREATE LASTCHILD OF creationPtr1 DOMAIN('XMLNSC')
PARSE(bodyBlob1,InputRoot.Properties.Encoding,InputRoot.Properties.CodedCharSetId);
Exception:
Caught exception and rethrowing Error detected, rethrowing
Procedures.XXXXX_MsgFlow_Compute.Main 22.3 RETURN TRUE; XML Parsing Errors have occurred An XML parsing error has occurred while parsing the XML document 1504 2 1 1 An invalid XML character (Unicode: 0x3f) was found in the prolog of the document. /Root/XMLNSC
Here is the POST message:
http://{HostName}:7080/PostSvc1?User=abcd&Password=abcd&Input=%3C%3Fxml+version%3D%221.0%22+encoding%3D%22UTF-8%22%3F%3E |

Did you look at the LocalEnvrionment in a TraceNode? If you do you should see that your url-decoded querystring is in the LocalEnvironment. You never need to use the BLOB message in this case as the contents of the BLOB is parsed out into name-value pairs that are placed into the LocalEnvrionment!
Kind Regards,

unfortunately, i see only the Request identifier
( ['MQROOT' : 0x791a8c0]
(0x01000000:Name):Destination = (
(0x01000000:Name):HTTP = (
(0x03000000:NameValue):RequestIdentifier = X'414d5120574d42363131514d202020203884504b2000a303' (BLOB)

Client code to post the message:

import java.net.URL;
import java.net.URLConnection;
public class XmlPost {
public XmlPost() {
}
public static void main(String[] args) {
String postUrl ="http://localhost:7080/PostSvc";
try
{
URL url = new URL( postUrl );
URLConnection postCon = url.openConnection();
postCon.setDoInput(true);
postCon.setDoOutput(true);
postCon.setUseCaches(false);
postCon.setDefaultUseCaches(false);
OutputStreamWriter writer = new OutputStreamWriter( postCon.getOutputStream() );
writer.write( buildXmlRequest().toString());
writer.flush();
writer.close();
InputStreamReader reader = new InputStreamReader( postCon.getInputStream() );
StringBuilder buf = new StringBuilder();
char[] cbuf = new char[ 2048 ];
int num;
while ( -1 != (num=reader.read( cbuf )))
{
buf.append( cbuf, 0, num );
}
String result = buf.toString();
System.out.println( "\nWebservice Response:\n" + result );
}
catch( Throwable t )
{
t.printStackTrace( System.out );
}
}
public static String buildXmlRequest() {

String msg = "?User=abcd&Password=abcd&Input=%3C%3Fxml+version%3D%221.0%22+encoding%3D%22UTF-8%22%3F%3E";
System.out.println("\n Webservice XML Request:\n" + msg + "\n");
return msg.toString();
}

Are you using 6.1.0.4?
Did you check the box on the HTTPInput node that mgk mentioned, and redeploy? |

Yes, i followed her steps one by one..
HTTPInput Properties:
Message Domain = BLOB
Checked Parse Query String
Parsed the XML using CREATE PARSE i attached the trace between HTTP Input and Compute ...couldn't find anything |
