Clusterwide File Transfer

[soon5]

Hy there,

I have a JBoss 4.2.1 Cluster running with two nodes, but more in plan. I use Farm deployment for my war / ear files, which works fine so far. Some of the Web Apps need some datafiles, which are stored in the /data Folder.

I have to add or replace these files, thats why i didn't put them into the War file, because then i had to do a redeployment every time i replace a file.

My Question is, is there a Chance, that i can use the ClusterFileTransfer system, to automaticaly replicate files in the /data Folder to the cluster, like it is done in farm deployment?

That whould be great, because then i wouldn't have to replace the Files on all nodes by myself.

Thanks so far,

Greetings Soon5

I forgot to mention, programmatic ways using the JBoss API or hinds in that direction are welcome as well. I don't expect an out of the box solution.

I also would like to do that: reuse that jboss code to distribute my config files to all nodes in the cluster.

What i currently do is this: i just put them in the farm folder, and ignore the deployment-errors about them :)

then i make a softlink deploy/data.war to the farm folder; this way, my remote java client application can also download these config files (but of course also my ear file huh)

I read the file in my server code like this:

properties.load(new FileInputStream(new File(System.getProperty("jboss.server.home.dir") + "/deploy/data.war/config.properties")));

Hy,

I have another workaround. I have a replicated TreeCache in my Cluster. I read the Files on one node, and put them as byte[] into the cache, with an aditional String what the Filename is.

The Array is instantlly replicated to the other nodes. There I take the File from the Cache and write it to the Disk again.

I have a little more Code, which checks the timestamp of all Files in the Cluster, so a new one is replicated instanttly, and some other to clean the cache after Transfer, because I don't want to keep the byte[] in the cache for the whole time.

But whats the benefit in using the TreeCache? I don't have to care about the network.
