<cluster>

The top-level <resin> tag contains any <cluster> defined for a deployment. It also provides an environment for class-loaders, logging and shared resources.

                    <cluster> configures a set of servers used for load-balancing and for sharing distributed sessions.

                    <cluster-default> configures common configuration for all clusters.

                    <resin>

                    <resin> is the top-level configuration tag for the resin.conf file. The <resin> tag needs to specify the Resin namespace, to allow for validation of the configuration file.

                    The environment of the top-level <resin> is the global classpath. This environment can be important for <log> configuration for threads which run with using only the global class loader. Because the <resin> environment does not have a dynamic class loader, dynamically loaded classes, like custom jars in resin/lib are not available.

                    <root-directory> specifies the base directory for the contexts. All EL-style directory paths are relative to the root-directory.

                    <security-manager>

                    <security-manager> enables the use of the security manager for the JVM.

  <security-manager/>
  ...
                    <security-provider>

                    <security-provider> adds one or more security providers. Each entry specifies the name of a security provider class. The name is used to instantiate an instance of the object, which is then passed to Security.addProvider.

                    Common Tags

                    There are some conventions for tag names that provide similar functionality.

                    fileset

                    <fileset> provides the ability to match a set of files. It is modelled after the ant tag by the same name.

                    dirthe starting directoryrequired
                    includean include patterndo not include all files
                    excludean exclude patterndo not exclude any files

                    A pattern can contain two special characters: '*' and '**'. '*' matches any part of path, but does not match the path separator. '**' matches any part of a path, including the path separator. 

                    <fileset dir="lib">
  <include name="*.jar"/>
</fileset>

MATCH    lib/foo.jar
MATCH    lib/bar.jar
NO MATCH lib/baz/foo.jar

                    <fileset dir="lib">
  <include name="**/*.jar"/>
</fileset>

MATCH    lib/foo.jar
MATCH    lib/bar.jar
MATCH    lib/baz/foo.jar

                    Startup and Redeploy Mode

                    The startup-mode is used in a number of places to determine the behaviour of a resource when the server starts.

                    The startup-mode has three values: "automatic", "lazy", and "manual".

                    • automatic - starts the resource on server start (default)
                    • lazy - starts the resource on the first use
                    • manual - waits for JMX to start the resource

                    The redeploy-mode is used in a number of places to determine the behaviour of a resource when it is replaced or modified while the server is running.

                    The redeploy-mode has two values: "automatic", and "manual".

                    • automatic - restarts the resource when it is modified (web.xml, *.class, *.war, etc).
                    • manual - waits for JMX to restart the resource when changes occur.
