writing file in a cluster

[alflaro]

Hi,
I have a simple J2EE web application developed with Struts and with POJO for business logic (no EJB). Now I have to deploy the application on a cluster of two Jboss 3.2.6 servers.
The problem is that the application writes files on server file system, like Excel files and XML files.
Which is the best solution on a cluster ? Do I have to insert in the database the data that now are in the files or JBoss supports in some way to replicate directories contents?
Thanks a lot.

Your problem is in no way JBoss specific.

You have a number of options open to you:

1. Write to a shared file system(e.g., NFS, Samba, etc)
2. Write to a JDBC database
3. Use JBossCache - write the contents as Objects (or maybe byte[]'s if they have no specific Java representations). JBossCache can then be configured to replicate contents across server instances. And if you wish, JBossCache can be configured with a cache loader (see manual) so that the cache can be backed up to a file system, database, etc.

Once written to disk, are these files accessed by other systems?

No the files are written and read only by the application.

JBossCache (perhaps backed by a JDBC cache loader) would be ideal for this then ...
