## org.springframework.jms.support.converter
Class SimpleMessageConverter102

    java.lang.Object
      org.springframework.jms.support.converter.SimpleMessageConverter
          org.springframework.jms.support.converter.SimpleMessageConverter102

All Implemented Interfaces:
  MessageConverter

    public class SimpleMessageConverter102

extends SimpleMessageConverter

A subclass of `SimpleMessageConverter` for the JMS 1.0.2 specification, not relying on JMS 1.1 methods like SimpleMessageConverter itself. This class can be used for JMS 1.0.2 providers, offering the same functionality as SimpleMessageConverter does for JMS 1.1 providers.

The only difference to the default SimpleMessageConverter is that BytesMessage is handled differently: namely, without using the `getBodyLength()` method which has been introduced in JMS 1.1 and is therefore not available on a JMS 1.0.2 provider.

Since:
  1.1.1
Author:
  Juergen Hoeller
See Also:
  `BytesMessage.getBodyLength()`

Field Summary
`static int` | `BUFFER_SIZE`

Constructor Summary
`SimpleMessageConverter102()`

Method Summary
`protected byte[]` | `extractByteArrayFromMessage(BytesMessage message)` Overrides superclass method to copy bytes from the message into a ByteArrayOutputStream, using a buffer, to avoid using the `getBodyLength()` method which has been introduced in JMS 1.1 and is therefore not available on a JMS 1.0.2 provider.

Methods inherited from class org.springframework.jms.support.converter.SimpleMessageConverter
