Hi,

I'm trying to send a BLOB as an email attachment.

First I send a XML-structure with a BLOB to my JCN with the mail code.

...
Set OutputRoot.XML.Message.Data = CAST(ASBITSTREAM(InputBody) AS CHAR CCSID InputRoot.MQMD.CodedCharSetId);
...

Then I try to cast it to a Java byte, but I get a java class cast exception, ...

byte[] data = (byte[]) message.evaluateXPath("string(//Data)");

Can anyone help?


And how can I attach the data? Is this code right?

// attach the file to the message
ByteArrayDataSource ds = new ByteArrayDataSource(data, "application/x-any");
mbp2.setDataHandler(new DataHandler(ds));

Did you look at the javadoc for evaluateXPath? Is it capable of returning a byte[]?

Did you look at the samples in the section on using xPath in the info center?

You're right it needs to be.


Stringdata = (String) message.evaluateXPath("string(//Data)");
