Doing network I/O on the user interface (UI) thread is bad. Most developers know that and can tell you why; unfortunately, it's still done.

Exploring the Directory Structure

Installing the JBoss distribution creates a jboss-4.0.4 directory that contains server start scripts, JARs, server configuration sets and working directories. You need to know your way around the distribution layout to locate JARs for compiling code, updating configurations, deploying your code, etc.

jboss directory structure

JBoss top-level directory structure -

Directory	Description
bin	All the entry point JARs and start scripts included with the JBoss distribution are located in the bin directory.
client	The JARs that are required for clients that run outside of JBoss are located in the client directory.
server	The JBoss server configuration sets are located under the server directory. The default server configuration set is the server/default set. JBoss ships with minimal, default and all configuration sets. The subdirectories and key configuration files contained default configuration set.
lib	The lib directory contains startup JARs used by JBoss. Do not place your own libraries in this directory.

JBoss server configuration directory structure -

Directory	Description
conf	The conf directory contains the jboss-service.xml bootstrap descriptor file for a given server configuration. This defines the core services that are fixed for the lifetime of the server.
data	The data directory is available for use by services that want to store content in the file system.
deploy	The deploy directory is the default location the hot deployment service looks to for dynamic deployment content. This may be overridden through the URLDeploymentScanner URLs attribute.
lib	The lib directory is the default location for static Java libraries that should not be hot deployed. All JARs in this directory are loaded into the shared classpath at startup.
log	The log directory is the directory log files are written to. This may be overridden through the conf/log4j.xml configuration file.
tmp	The tmp directory is used by JBoss to store temporarily files such as unpacked deployments.
