Convert String to a JMS BytesMessage in Java

Question

I am trying to convert a String to a JMS BytesMessage. Is there a good way to do this?

I need to do this because I have a method that takes in a String that is decrypted and I need to convert it into a BytesMessage in order to decrypt the message.

Thanks

Answer 1

 byte[] bArray = "foo".getBytes("UTF-8");
 BytesMessage msg = session.createBytesMessage(); // throws JMSException
 msg.writeBytes(bArray);

Of course, like Arcadien said, you need to execute the code in an appropriate environment to obtain the javax.jms.Session object from.

Answer 2

you can use

byte[] String#getBytes()

to get a byte array from a string and write it to a ByteMessage

Answer 3

A bit late, but better late than never.

The @Carlo answer is essentially correct, except that you must catch an exception if you use getBytes with a String parameter.

Here is a variation (of the getBytes call) that will not throw an exception:

final byte[] byteArray = "blammy".getBytes(StandardCharsets.UTF_8);
final BytesMessage bytesMessage = session.createBytesMessage();

bytesMessage.writeBytes(byteArray);

The StandardCharsets class defines charsets that are guaranteed to be available on every implementation of the Java platform.
