Ok, So I decided to go back to the drawing board and decided to run some
tests.
First, I implemented a very simple decoder that contains the following code:
@Override
protected boolean doDecode(IoSession is, IoBuffer ib,
ProtocolDecoderOutput pdo) throws Exception {
System.out.println("IoBuffer hasRemaining: " + ib.hasRemaining());
System.out.println("IoBuffer remaining: " + ib.remaining());
byte[] data = new byte[ib.remaining()];
ib.get(data);
System.out.println("IoBuffer read: " + new String(data));
return true;
}
Then I implemented my route in the camel-context as...
<camel:camelContext xmlns="http://camel.apache.org/schema/spring";>
<camel:route>
<camel:from
uri="mina2:tcp://10.5.60.60:9000?codec=#gilbarcoDecoder" />
<camel:bean ref="testBean"/>
</camel:route>
</camel:camelContext>
When I run this it will successfully read the input and output the received
message to the console. However when I change the route to..
<camel:camelContext xmlns="http://camel.apache.org/schema/spring";>
<camel:route>
<camel:from
uri="mina2:tcp://10.5.60.60:9000?disconnectOnNoReply=false;codec=#gilbarcoDecoder"
/>
<camel:bean ref="testBean"/>
</camel:route>
</camel:camelContext>
Then I get the following error message and it never calls the doDecode
method..
org.apache.camel.CamelException:
org.apache.mina.filter.codec.ProtocolDecoderException:
org.apache.mina.core.buffer.BufferDataException: dataLength: 1347375948

Not sure exactly why this is occurring. Is it the way I have configured my
route? Or is this a bug in the Mina2 2.11.1 component?
