I suggest using jgroups 2.2.6 and change org.jgroups.util.ContextObjectInputStream as
it is implemented in JDK1.4:
package org.jgroups.util;
import java.io.IOException;
import java.io.ObjectStreamClass;
import java.io.InputStream;
import java.io.ObjectInputStream;
import java.util.HashMap;
/**
* ObjectInputStream which sets a contact classloader for reading bytes into objects.
Copied from
* MarshalledValueInputStream of JBoss
* @author Bela Ban
* @version $Id: ContextObjectInputStream.java,v 1.1 2004/07/26 15:26:46 belaban Exp $
*/
public class ContextObjectInputStream extends ObjectInputStream {
/**
* A class wide cache of proxy classes populated by resolveProxyClass
*/
private static HashMap classCache = new HashMap();
private static final HashMap primClasses = new HashMap(8, 1.0F);
static {
primClasses.put("boolean", boolean.class);
primClasses.put("byte", byte.class);
primClasses.put("char", char.class);
primClasses.put("short", short.class);
primClasses.put("int", int.class);
primClasses.put("long", long.class);
primClasses.put("float", float.class);
primClasses.put("double", double.class);
primClasses.put("void", void.class);
}
/**
* Creates a new instance of MarshalledValueOutputStream
*/
public ContextObjectInputStream(InputStream is) throws IOException {
super(is);
}
protected Class resolveClass(ObjectStreamClass v)
throws IOException, ClassNotFoundException {
String className = v.getName();
Class resolvedClass = null;
// Check the class cache first if it exists
if (classCache != null) {
synchronized (classCache) {
resolvedClass = (Class) classCache.get(className);
}
}
if (resolvedClass == null) {
ClassLoader loader =
Thread.currentThread().getContextClassLoader();
try {
resolvedClass = loader.loadClass(className);
} catch (ClassNotFoundException e) {
/* This is a backport von JDK 1.4's
java.io.ObjectInputstream to support
* retrieval of primitive classes (e.g. Boolean.TYPE)
in JDK 1.3.
* This is required for org.jgroups.blocks.MethodCall
to support primitive
* Argument types in JDK1.3:
*/
resolvedClass = (Class) primClasses.get(className);
if (resolvedClass == null) {
/* Use the super.resolveClass() call which
will resolve array
classes and primitives. We do not use this by
default as this can
result in caching of stale values across
redeployments.
*/
resolvedClass = super.resolveClass(v);
}
}
if (classCache != null) {
synchronized (classCache) {
classCache.put(className, resolvedClass);
}
}
}
return resolvedClass;
}
}
