Hi all,
using IBM MB version 5, I need to extract from an XML file with namespaces an element that contains a copybook.
In the flow, first I have correctly extracted and copy in the environment the field using the XMLNS domain, and then I make a reset content descriptor of the domain because in version 5 the FolderBitStream option works only in XML domain.
The application that produce the XML file is a java application and people responsible of the creation of the XML file say that they are able to insert the copybook in the XML file only converting it in a xsd:base64Binary type. In this way I have tried to extract the copybook without success
Then I made a test: using an XML editor I have inserted the copybook as xsd:Binary in the ESQL (now it is readable) and I had a strange behavior:
The classical code passing the environment variable converted with ASBITSTREAM function doesnâ€™t work, while if I parse directly the variable it does.
CALL CopyMessageHeaders();
SET OutputRoot.Properties.MessageSet = 'G3OOQVC002001';

SET OutputRoot.Properties.MessageType = 'msg_CWIMPS';
SET OutputRoot.Properties.MessageFormat = 'CWF1';

DECLARE inCCSID INT InputProperties.CodedCharSetId;
DECLARE inEncoding INT InputProperties.Encoding;
DECLARE option INTEGER BITOR (RootBitStream, ValidateNone, ValidateDeferred, ValidateLocalError);
DECLARE option1 INTEGER BITOR (FolderBitStream, ValidateNone, ValidateDeferred, ValidateLocalError);
DECLARE creationPtr REFERENCE TO OutputRoot;
DECLARE inBitStream BLOB ASBITSTREAM(Environment.Variables.datoInputFunzioneMC OPTIONS FolderBitStream);
DECLARE i INTEGER;
SET i = LENGTH(inBitStream);
CREATE LASTCHILD OF creationPtr DOMAIN('MRM')
PARSE(Environment.Variables.datoInputFunzioneMC --> with inBitStream doesnâ€™t work
OPTIONS option
ENCODING inEncoding
CCSID inCCSID
SET OutputRoot.Properties.MessageSet
TYPE OutputRoot.Properties.MessageType
FORMAT OutputRoot.Properties.MessageFormat
);

My questions are:
1) Is it true that the unique way is use the xsd:base64Binary type to insert the copybook in the XML element? Or does anybody know other way in java?
2) If the xsd:base64Binary is right how can I parse it?
3) Why my example works only passing directly the environment variable because it is a xsd:Binary?

Thank you very much
