JBoss - know more about the JBoss directory structure

Fundamentally, the JBoss architecture consists of the JMX MBean server, the microkernel, and a set of pluggable component services - the MBeans.

The JBoss Application Server ships with three different server configurations. Within the <JBoss_Home>/server directory, you will find three subdirectories: minimal, default and all. The default configuration is the one used if you don’t specify another one when starting up the server.

If you want to know which services are configured in each of these instances, look at the jboss-service.xml file in the <JBoss_Home>/server/<instance-name>/conf/ directory and also the configuration files in the <JBoss_Home>/server/<instance-name>/deploy directory.

JBoss 4.0 features an embedded Apache Tomcat 5.5 servlet container.
  • conf --> The conf directory contains the jboss-service.xml bootstrap descriptor file for a given server configuration. This has the jboss-log4j.xml file which configures the Apache log4j framework category priorities and appenders used by the JBoss server code.  
  • data --> The data directory is available for use by services that want to store content in the file system. It holds persistent data for services intended to survive a server restart. Serveral JBoss services, such as the embedded Hypersonic database instance, store data here. 
  • deploy --> The deploy directory contains the hot-deployable services (those which can be added to or removed from the running server). You deploy your application code by placing application packages (JAR, WAR and EAR files) in the deploy directory. The directory is constantly scanned for updates, and any modified components will be re-deployed automatically.  
  • lib --> This directory contains JAR files (Java libraries that should not be hot deployed) needed by this server configuration. You can add required library files here for JDBC drivers etc. All JARs in this directory are loaded into the shared classpath at startup.  
  • log --> This is where the log files are written. JBoss uses the Jakarta log4j package for logging and you can also use it directly in your own applications from within the server. This may be overridden through the conf/jboss-log4j.xml configuration file. The file boot.log logs the JBoss startup and shut down notifications. This log is overwritten each time JBoss is (re)started. 
  • tmp --> The tmp directory is used for temporary storage by JBoss services. The deployer, for example, expands application archives in this directory.  
  • work --> This directory is used by Tomcat for compilation of JSPs.

Basic design decisions for a commerce search setup ( with an ATG Search view)

In this blog I would like to explain the basic set of configuration/design decisions needed to setup an ATG search project. Most of these design decisions are common for all Enterprise search applications. 1. Decide the searchable properties :   This means the properties that the business want the user to search in the ecommerce platform. In ATG search these are configured as the text properties in the product-catalog-output-config.xml ( the definitionFile of the \atg\commerce\search\ProductCatalogOutputConfig). Usually the displayName of product/sku, displayName of department/category/sub-category, skuId, brandName are the properties configured as searchable. 2. Decide the search refinement properties or the faceted properties :   After a user search for a keyword, search refinement is the next step done to filter his results. ATG supports the search refinement using the Faceted Search concept. Read more about facted search @...

ATG Search troubleshooting tips

In this blog, I have listed some basic ATG Search troubleshooting tips in some general scenarios. 1. If the index did not deploy, consider the following possible causes : Is the DeployShare property configured @ /atg/search/routing/LaunchingService component ?  Is enough space available @ deployment share box for the index ?  Are the RMI ports configured correctly in the RoutingSystemService component ?  If the search engine application is running in a separate box, this application is invoked through a RemoteLauncher running in these boxes. Check whether these RemoteLaunchers are running in these boxes ? 2. If you have trouble in launching one or more search engines, try the following remedies: If the Search engine is standalone, set the /atg/search/routing/LaunchingService component’s engineDir property to the absolute path of the Search engine directory.  3. Search unavailable in the estore page, even when the SearchEngine is in "Running" st...

ATG - quick reference to commonly used DSP Tags

In this blog, I would like to give a quick reference to the most commonly used DSP Tags.Note that in this DSP tag details : bean refers to a Nucleus path, component name, and property name param refers to a Page parameter value refers to a Static-value var refers to a EL variable id refers to a scripting variable ============================================================== 1.dsp:importbean     example: <dsp:importbean bean="/atg/dynamo/droplet/Switch"/> ============================================================== 2.dsp:page     usage: It encloses a JSP. The dsp:page invokes the JSP handler, which calls the servlet pipeline and generates HTTPServletRequest.    example:    <dsp:page> ..... </dsp:page> ============================================================== 3.dsp:include     usage: Embeds a page fragment in a JSP.     example:   <dsp:include src="/myPage/Result...
