amf3Output.writeObject(animal);
And the code on flash ... |

I am wondering how to use serielizable object. My question is this: Since the server side don't know anything about the serializable object that received from a remote client, how can I use the methods in this object at server side? I wrote some code, the server read a object from client, and use the object like this: object.getInfo() , the ... |
Idunno, what's "a lot"? Compared to file IO? A database query? Including a .js file? Parsing XML from a partner system? Any bit of wasted effort in your algorithms or designs could cost you as much. Yes, there is non-zero overhead to any serialization. Hand coding your own might be more efficient than the reflection in the library. Or not. Try ... |

Problem: in.readObject() throws a ClassNotFoundException exception because it can't find the class a.package.path.CommandMessage. (Sorry about the double-posting. I posted this to I/O and Streams, then looking at the discussion here, it seemed even reasonabler to post here.) I'm sending a serialized object via socket; using writeObject(), readObject(). There are now two versions of the same system that are communicating with one ... |
Hey there, I want to send objects via sockets. The standard approach seems to be using Java's Serialization. However I got the input this would be really fragile and insecure. Security is not a problem at all, but I do not want to implement a fragile design which is hard to change afterwards, Are there good alternatives? We thought of a ... |

Hence in the beginning of the connection I am opening ObjectOutputStream, ObjectInputStream, BufferedReader and DataOutputStream both sides. Stop right there. That can't possibly work. You can only use one stream or reader for each side of a socket connection. Otherwise they compete, buffer data that the other one wants, etc. If you want to use Serialization, you must use an ObjectOutputStream. ... |

Hi all, I've question what is better to use ObjectStream or DataStream to send and read information on serialized socket. Additional information I want to send data from base so it's mean i.e. update table1var1='1', var2='2', var3='30.01.2006', var4='nameoftable' and also other information for example on the beginning "start:" then three loops - each row from database and on the end "end" ... |
