i use javaMail to download the message from the server and i want to save it to the database,
know that message doesn't implement serialization,I have to use it's inputStream to save to the database like these:
pStmt.setBinaryStream(4,
msgs.getInputStream(),msgs.getSize()); [4 field is blob data]
pStmt.execute();
but when i want to get it out from the database as the form of Message,how can i do?
i have attampted to use this sentence:
Message msg=(Message)resultset.getObject(4); and there is an classcastException thrown

Using this method, the message is not saved, only its content is, so that why you can't cast to a Message object. You will have to create a new message, and then and the content from the db into the message.
