Emmanuel Lecharny resolved DIRMINA-923.
---------------------------------------
Resolution: Fixed
Sounds a decent proposal.
I have applied the suggested modification in
http://svn.apache.org/viewvc?rev=1418344&view=rev
> Many ClassNotFoundException in AbstractIoBuffer.putObject()
> -----------------------------------------------------------
>
> Key: DIRMINA-923
> URL: https://issues.apache.org/jira/browse/DIRMINA-923
> Project: MINA
> Issue Type: Bug
> Components: Filter
> Affects Versions: 2.0.7
> Environment: Win 7, Java 7, MINA jars wrapped in NetBeans module.
> Reporter: Jörg Michelberger
> Original Estimate: 1h
> Remaining Estimate: 1h
>
> Using ObjectSerializationEncoder causes a lot of ClassNotFoundExceptions in
> AbstractIoBuffer.putObject().
> In putObject() is Class.forName(String className) used for supporting the
> serialization process. This uses the Classloader of the calling thread. There
> is no guarantee that the calling thread is able to load all classes that
> should be serialized. Instead of using the caller thread Classloader the
> Thread.currentThread().getContextClassLoader() shoud be used to do the job,
> or the Classloade which should be used has to be passed in Constructor of
> ObjectSerializationEncoder, same way the ObjectSerializationDecoder does.
> When using MINA in a modular Container like NetBeans the
> Thread.currentThread().getContextClassLoader() can be used inside without any
> API change.
> Please consider this change for 2.0.8.
> See appended code of AbstractIoBuffer.putObject() which works in NetBeans
> modular framework:
> public IoBuffer putObject(Object o) {
> int oldPos = position();
> skip(4); // Make a room for the length field.
> try {
> ObjectOutputStream out = new ObjectOutputStream(asOutputStream())
> {
> @Override
> protected void writeClassDescriptor(ObjectStreamClass desc)
> throws IOException {
> try {
> if (!desc.forClass().isArray()) {
> Class<?> clz =
> Thread.currentThread().getContextClassLoader().loadClass(desc.getName());
> if (!Serializable.class.isAssignableFrom(clz)) {
> // NON-Serializable class
> write(0);
> super.writeClassDescriptor(desc);
> } else { // Serializable class
> write(1);
> writeUTF(desc.getName());
> }
> } else {
> write(0);
> super.writeClassDescriptor(desc);
> }
> } catch (ClassNotFoundException ex) { // Primitive types
> write(0);
> super.writeClassDescriptor(desc);
> }
> }
> };
> out.writeObject(o);
> out.flush();
> } catch (IOException e) {
> throw new BufferDataException(e);
> }
> // Fill the length field
> int newPos = position();
> position(oldPos);
> putInt(newPos - oldPos - 4);
> position(newPos);
> return this;
> }
