The message length sent from Java Bridge and read from ActionScript Bridge is consistent.

[GoogleCodeExporter]

This bug cause various types of unexpected behaviors:

What steps will reproduce the problem?
1. Print the byte array size (code "bytes.length") from the Java Bridge 
class inthe method sendMessage(...)
2. In the ActionScript Bridge, print the readed __totalBytes after the line 
"__totalBytes = __client.readByte();"

What is the expected output? What do you see instead?
Expected: 
The __totalBytes variable in ActionScript should have the same value of 
"bytes.length" in Java.

Get: 
A different value.

Cause:
This happens because the byte array length is write in raw mode on the 
socket to the ActionScript bridge, but the "__client.readByte();" requires 
that the byte is write in AMF3 encoding.

Using an Amf3Output class to convert the byte array length in AMF3 using 
writeInt(...) in Java Bridge writing the relative encoded byte array and 
reading the "__totalBytes" using readInt() in ActionScript Bridge fix the 
problem.

Sorry, the right summary should be "The message length sent from Java Bridge 
and read 
from ActionScript Bridge is NOT consistent."

Can you please brief me on how to send objects via merapi??

There are the Bridge classes with the "brute" fix for this issue. 
The ActionScript fix is simple (row 444: used readInt instead of readByte). The 
Java 
fix is more complex (rows from 237 to 249: used an Amf3Output class to encode 
the byte 
array length of the message on the socket).

Bye.

Sorry. My doubt was regarding sending an array or any other object from java to 
flex
(and vice versa) via merapi. If you have a sample code for the same that will 
be 
great !!

Thanks in advance

To pass other data, you must define a new class that extends the Message class 
of 
merapi both in Java and ActionScript, adding your custom fields. This way, the 
conversion should happen like in BlazeDS.

Is the brute fix by lukakama stable as I don't see it being used(neither in the 
trunk
version nor in the branch version of Bridge.java) .

And in case it is not then what is the solution for this bug?
