Hey Manik I subclass TcpDelegatingCacheLoader in this way:
package org.jboss.cache.loader.tcp;
|
| import java.util.Iterator;
| import java.util.List;
| import java.util.Map;
| import java.util.Set;
|
| import org.jboss.cache.Fqn;
| import org.jboss.cache.Modification;
| import org.jboss.cache.loader.DelegatingCacheLoader;
|
| public class MyTcpDelegatingCacheLoader extends TcpDelegatingCacheLoader {
|
| @Override
| protected void delegatePut(Fqn name, Map attributes) throws Exception {
| //nothing to do
| }
|
| @Override
| protected Object delegatePut(Fqn name, Object key, Object value) throws Exception {
| //nothing to do
| return null;
| }
|
|
| @Override
| protected Map delegateGet(Fqn arg0) throws Exception {
| return null;
| }
|
| @Override
| protected Set delegateGetChildrenNames(Fqn arg0) throws Exception {
| return null;
| }
|
| @Override
| protected void delegatePut(List modifications) throws Exception {
| synchronized (out)
| {
|
| out.reset();
| out.writeInt(DelegatingCacheLoader.putList);
| int length = modifications != null ? modifications.size() : 0;
| out.writeInt(length);
| if (length > 0)
| {
| for (Iterator it = modifications.iterator(); it.hasNext();)
| {
| Modification m = (Modification) it.next();
|
| if (m.getType() == Modification.REMOVE_NODE) { //added by me
| m.writeExternal(out);
| }
| }
| }
| out.flush();
| Object retval = in.readObject();
| if (retval instanceof Exception)
| throw(Exception) retval;
| }
|
| }
|
|
| }
and I configure my Caches in this manner:

Later I try to store an object in my DelegatingCacheLoader through JMX Console (key= name, value = myname) and when i invoke the put Operation in DelegatingCacheLoader service this never end, it seems to be waiting for something. No error message is thrown. did I some wrong or i need to configure something else?
Thanks in advance
