Hi to all,
For a requeriment, I have to Zip the Payload that cames in the XMLNSC Domain and need to be sennt as a Zipped String to a MQ Queue.
My idea was to zip the hole Payload of the XMLNSC domain, create BLOB domain with that zipped message and delete the XMLNSC Domain.
I could figure it out with a Java Compute, and a Compute, but I am trying to just use the Java Compute, here is muy Code:
FIRST THE JAVA:
MbOutputTerminal out = getOutputTerminal("out");
MbMessage inMessage = contact admin.getMessage();
MbMessage outMessage = new MbMessage(inMessage);
MbElement msgBody;
try {
// ZIP THE MESSAGE
String ccsid = inMessage.getRootElement().getFirstElementByPath("Properties/CodedCharSetId").getValueAsString();
msgBody = outMessage.getRootElement().getLastChild();
Integer ccsidValue = new Integer(ccsid);
byte[] testByteStream = msgBody.toBitstream(null, null, null, 0, ccsidValue, 0);
String message = new String(testByteStream);
String compressMessage = ZipUtils.getInstance().compressToString(message);
//CREATE A NEW ELEMENT CALLED BLOB AND DELETE THE TREE XMLNSC
MbElement root = outMessage.getRootElement();
MbElement msgElement = root.getLastChild();
msgElement.detach();
root.createElementAsLastChild(MbElement.TYPE_NAME_VALUE,"BLOB", compressMessage);
MbMessageAssembly outAssembly = new MbMessageAssembly(contact admin,outMessage);
out.propagate(outAssembly);
}
The OUTPUT of this node is a RootTree with PROPERTIES, MQMD and BLOB subtrees, but the BLOB is not recognized as a DOMAIN and then I can not see it enqueued the PAYLOAD. The result is a message enqueued without PAYLOAD (the zipped message).
So I nedd to put a Compute After this with the following code:
SET OutputRoot.Properties = InputRoot.Properties;
SET OutputRoot.MQMD = InputRoot.MQMD;
CREATE LASTCHILD of OutputRoot DOMAIN('BLOB') Name 'BLOB';
SET OutputRoot.BLOB.BLOB=CAST (InputRoot.BLOB AS BLOB CCSID InputRoot.Properties.CodedCharSetId);
So, I want to now HOY to create properly the BLOB Domain in JAVA in order to just use that node. I have search in the inforcenter and this Forum, but I couldn´t still find the answer.
Thanks in Advance!

I have found a solution. I will post the solution when I am back at the office!

relatively easy. You are missing the declaration of the parser:
You should have
| Code: |
MbElement parser = root.createElementAsLastChild(MbBLOB.BLOB_NAME); --from memory...
parser.createElementAsLastChild(MbElement.TYPE_NAME_VALUE,"BLOB", compressMessage); |
Also your conversion to string is not good.
Do not use the input ccsid. Use CCSID 1208 (utf-8 ) you can then specify the same in the conversion to String : new String(byte[], "UTF-8");
Have fun

If the capture of the bitstream is occurring near the start of the flow then it's best to use InputRoot.Properties.CodedCharSetId. That will ensure that the input bitstream can simply be used as-is.
If you choose a CCSID that is not the same as the input then the parser will need to parse the entire message and re-serialize it in the new character encoding.
However, I do think that this looks strange:
| Code: |
String message = new String(testByteStream);
String compressMessage = ZipUtils.getInstance().compressToString(message); |
Surely you want the zip utility to compress the raw bytes, not some string that was created from the bytes? |

Almost. That should be MbBLOB.PARSER_NAME (which resolves to "NONE", not "BLOB"). The parser class name does not always match the parser or root element name, so it's usually a good idea to use the built-in parser constants, rather than hardcoding literal values. |

I have solved it with:
MbElement outParser = root.createElementAsLastChild(MbBLOB.PARSER_NAME);
outParser.createElementAsLastChild(MbElement.TYPE_NAME_VALUE, "BLOB", compressMessage.getBytes());
The want to ZIP the entire message!
Thanks to all!!!
