Hello all. I want to understand how to use this kind of feature. Anyone knows how using this in a desktop application, without running on JBoss? I´ll really appreciate.

So you want to use distributed caching in a standalone application ?

Why?

Because I´m in this situation: one application reads a collection of elements and other inserts data. While I´m inserting new objects in database, I want to read them all at runtime, and this isn´t happening.

According with Hibernate in Action...."The first-level cache is mandatory and can’t be turned off". So, the EHCache isn´t the recommended to my needs.

Any hint?

You can try and take a look at JBoss Cache: http://www.jboss.org/products/jbosscache

You can use this as a stand-alone cache aswell. :)

Well, I´m on the right way. I´m trying to resolve this:



Using code:



or xml:



But I can´t do that. I´m following a tutorial in jboss page, this: http://docs.jboss.org/jbcache/current/TreeCache/html/index.html#d0e205

Please help... :)

Ok, thanks for the help, but the problem persists. :-P

Um, well, if you're not going to be using JTA why exactly do you want to be using TreeCache (TreeCache, btw, = JBossCache)?

Why not just use EHCache?

I´m facing a problem:

One application inserts data and other reads, in differents JVM´s. I want, at runtime, to read all data while other application is inserting. This isn´t happening... Using TreeCache (from JBoss, yes), i´m trying to resolve this.

Any ideas?

don't you just need another isolation level then, because I don't really get where you want to go with TreeCache and the description you give that the application should do...

Is it that, while inserting in application 1, while reading in application 2, you want the already read data from application 2 to be automaticly updated by the inserts from 1 ?

nomania, to syncronize data from the caching of more than one JVM, I have to use a distributed cache. I saw this in this article: http://www.informit.com/articles/article.asp?p=353736&seqNum=5. I´m trying to test this type of cache, I want to learn how to use this feature doing a Hello example, just to understand.

Thanks all for the help. Any sugestions?

But the article also only mentions using TreeCache at an application server.

This is a better link I think: http://docs.jboss.com/jbcache/1.2.4/tutorial/html/

Where has this code snippet:

Basicly this is the minimum code to start the TreeCache in the current JVM (that of your stand alone application) :)
So you have your onw TreeCache object, instead of having to look it up in the JNDI of a application server.

The rest is up to you, doing the configurations ;)

Alright... I understood the basic steps of configuring the TreeCache... So I' ve to put all my objects I want in cache via code? Or this is something controlled by JTA?



I'm still getting the same warning of

How can I define this transaction manager lookup class?

To perform a lookup, I´ve to register an object of type TreeCache as a SessionBean right? Im my case (desktop application), how can I do that? RMI? I´m still stuck on it...

Solved!!! Thanks everybody!!! I saw the Dummy class and now I´m understanding.... :)
