By they way, we are using the AOPProxyCollections for replicating our
collections like HashMaps and Lists.
Could there be a botteneck in the proxies?

Whatever it be, we had a bad time with TreeCacheAOP.From our profiling, just a
get() that was doing some doing a lock ( some intent.lock package) was hogging
up cpu time...
Do u have any clue why this would take time..
We are using 1.2.x version of TreeCacheAOP..
We do have puts, and remove oper
-I mean, migrating to a different version of JBOSS App server.
Right now Im using 3.2.7, so will migrating to 4.0+ version help in
performance??
-Another quicky, right now we have tomcat with jboss.Would putting any other
webserver like Jetty etc help in handling http requests faster?

Thanks!This will definitely help..
What do you recommend for an App server migration?

1)I wanted to know if using TreeCacheAOP is scalable under alot of user load?
2)Can event interception get more expensive at some point of time during alot
of load?
3)How can we fine tune TreeCacehAOP if possible to improve performance?

I'm using JBOSS 3.2.7 and facing crisis on performance with around 300
users.We'll ofcourse we are squeezing out any expensive code, but I wanted to
know:
1)How JBOSS/Tomcat could be fine tuned to handle http requests faster?
Any configuration parameters?
2)Do we need to increase thread pool size
Thanks,this helped us in debugging things faster.
The problem was that Multicast routing wasn't enabled on the Network
tables,even though MULTICAST was enabled on the network interface.

Our firewall rules look OK.We've made all our local network machines entries in
the allow_hosts.rules(without any port specification).
Could the mcast_addr we used be possible wrong?

We have 2 CentOS4.0 Linux boxes running JBOSS 3.2.7.We are using JBOSS
TreeCache AOP(JBOSS Cache 1.2.0).
When we start both of our boxes, they seem not to be able to communicate with
each other and form a cluster.
It works perfectly on the windows machines.
Our boxes have 2 network interfaces on
Thanks!

OK.It seems replication of the UserSessionObject wasnt happening in the first
place..When the put was done only once in the hashmap,that was the only time
the object was replicated.After that it was just modification to the
POJO(UserSessionObject).
So the question is, do I need to Instrument the
Im using TreeCacheAOP.I am replicating a HashMap and objects stored in it(I
actually do a putObject on the hashmap)
The key to the HashMap is a string,and the value is an object of my own class
called UserSessionObject.
UserSessionObject has a field called userTimestamp of type Timestamp.
So aft
Makes sense..Thanks!

Aren't the Collection Proxies simple wrappers over the actual collection,just
the way EJBObjects are one layer over the actual beans?
Is there any reason why you need to create your own datastructures?
How do you compare the performance of your data structures over java's data
structures?

Hey,there is an issue in replicating "updated" changes in the following
scenario:
| Map proxyMap=(Map)cache.geObject("/aop/mymap");
| Set set=proxyMap.keySet();
| Iterator setIterator=set.iterator();
| while(setIterator.hasNext()){
| Object obj=setIterator.next();
| if(obj.someCond
Ideally, the Collection proxies should exactly behave the way normal Java
Collections/Maps do..
Atleast user knows what to expect out of it and
this would also prevent related issues popping up later on...

Is it possible to get a nightly build of the JBOSS Cache that has your fixes
for the time being until we dont have the 1.3 release?

Hey one more issue is there.
When I do the following:
Set set=map.keyset();
Iterator setIterator=set.iterator();
while(setIterator.hasNext()){
Object object= iterator.next();//object returned here is String and not Long
}
The Object returned by iterator.next() is actually a String and NOT Long.
I
OK got it,I can still put Long keys and while accessing it I can make them to
strings and still be access the object.
This workaround is then bearable, then changing the type of the key.
Thanks Scott!!

Thanks Scott, the workaround wouldn't be a good idea in our software since the
structure is used nearly everywhere.

Hey there is a small typo in the code..The following code
System.out.println(guidMap2.containsKey("8225676592564383"));.
should read as
System.out.println(guidMap2.containsKey(new Long("8225676592564383"))).

I'm using TreeCacheAOP (JBOSSCache version 1.2.4SP1) for which im storing a map
in the cache.
When i retrieve the map and do a get() or a containsKey() it returns a null or
a false value respectively for the given key.
This happens only when i have a Long object stored as a key in my HashMap. Whe
