a question about codec.serialization
I use ObjectSerializationCodecFactory in my mina server and client app .
I define a Map field in my requestmessage and in this Map i put Object[]
args and Class[] clazzes;
in the first bytebuffer I use Long ,but the seconde bytebuffer i use long.
I find first bytebuffer can be sent to mina server, but the second can't .

/////////////////////
in SocketIoProcessor doFlush(SocketSessionImpl session) , i find the code
below are executed in these two condition.
if (key.isWritable()) {
writtenBytes += ch.write(buf.buf());
}
I don't know why! it's so strange!

Posted by Mark <el...@gmail.com>.
Not sure how autoboxing works with serialization, but I would try using a
Long object to wrap your long primitive.

--------------------------------
The adjuration to be "normal" seems shockingly repellent to me; I see
neither hope nor comfort in sinking to that low level. I think it is
ignorance that makes people think of abnormality only with horror and allows
them to remain undismayed at the proximity of "normal" to average and
mediocre. For surely anyone who achieves anything is, essentially, abnormal.

Re: a question about codec.serialization
Posted by tiandike <wh...@21cn.com>.
I look at sourcecode in mina ByteBuffer:
ObjectInputStream in = new ObjectInputStream(asInputStream()) {
protected ObjectStreamClass readClassDescriptor()
throws IOException, ClassNotFoundException {
String className = readUTF();
Class<?> clazz = Class
.forName(className, true, classLoader);
return ObjectStreamClass.lookup(clazz);
}
}
why overrides ObjectInputStream.readClassDescriptor()??

Re: a question about codec.serialization
Posted by tiandike <wh...@21cn.com>.
My request has a Map and put a Class[] params in this map , and I put a long
class in the params.
I find exception is in the code ByteBuffer.getObject:
String className = readUTF();
Class<?> clazz = Class
.forName(className, true, classLoader);
return ObjectStreamClass.lookup(clazz);
when className is long ,Class.forName throws exception:

Re: a question about codec.serialization
Posted by tiandike <wh...@21cn.com>.
My request has a Map and put a Class[] params in this map , and I put a long
class in the params.
Class[] c= {long.class,int.class};
Map map = new HashMap();
map.put(1, c);
I find exception is in the code ByteBuffer.getObject:

Class<?> clazz = Class
.forName(className, true, classLoader);
return ObjectStreamClass.lookup(clazz);
when className is long ,Class.forName throws exception:

Re: a question about codec.serialization
Posted by tiandike <wh...@21cn.com>.
My request has a Map and put a Class[] params in this map , and I put a long
class in the params.
Class[] c= {long.class,int.class};
Map map = new HashMap();
map.put(1, c);
I find exception is in the code ByteBuffer.getObject:
String className = readUTF();
Class<?> clazz = Class
.forName(className, true, classLoader);
return ObjectStreamClass.lookup(clazz);
when className is long ,Class.forName throws exception:
my mina version is 1.1.4
