ATG and XML File Combination

An XML file might appear at several points in the CONFIGPATH. The ATG platform, at runtime, automatically combines all the XML files in the CONFIGPATH with the same name into a single composite file, which is then used by the appropriate component.

XML files are combined one tag at a time: in other words, tags are matched up, and the combination rules are applied to each pair of matched tags. XML file combination is controlled with an XML attribute named xml-combine. This attribute is used only in the preprocessing stage of XML file combination.

The xml-combine attribute can have the following values:

xml-combine = "replace"
xml-combine = "remove"
xml-combine = "append"
xml-combine = "append-without-matching" --> This is the same as xml-combine="append", except that embedded tags are not matched and combined recursively. The content is simply appended.
xml-combine = "prepend"
xml-combine = "prepend-without-matching"

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 Apach...

Eclipse plugin: InstaSearch – for quick search

InstaSearch is an Eclipse plug-in for performing quick and advanced search of workspace files. This will index the files and when you search for some file contents, it will look with in this index and the search results will be faster, just like the Goolge instant search. It uses Lucene ( http://lucene.apache.org/ ) for indexing and fast searching of files in the workspace. Each search result file then can be previewed using few most matching and relevant lines. A double-click on the match leads to the matching line in the file. Main Features Instantly shows search results Shows a preview using relevant lines Periodically updates the index Matches partial words (e.g. case in CamelCase) Opens and highlights matches in files Searches JAR source attachments Supports filtering by extension/project/working set Download / Installation In Eclipse Helios (3.6) please install using the Eclipse Marketplace from the Help menu http://marketplace.eclipse.org/s...

ATG CA - different activity sources used @ BCC

Read about how a new link can be added in BCC home page @ http://tips4ufromsony.blogspot.com/2012/03/atg-ca-bcc-home-screen-how-to-add-new.html Normally an ActivitySource.properties file define the set of actions that it supports under a genericActivityDefinitionFile. But some ActivitySource.properties define the actions using the workflowActivityDefinitionFiles. For example consider the default "Content Administration" , "SearchAdministration", " Merchanding " and "Personalization" options in BCC homepage. Below I listed the ActivitySource.properties and other properties for these links. To get all these activitysource names, just take the / atg/bizui/activity/ActivityManager component @ dyn/admin. Content Administration ActivitySource --> /atg/bizui/activity/PublishingActivitySource genericActivityDefinitionFile Search Administration ActivitySource --> /atg/bizui/...

Search engine shutdown call from the Estore instnace

When the estore or commerce instances are restarted the routing system service can send shut down requests to stale engines, this can be caused because of any of the following. 1. Some other instance marked the engine as stopped in the DB (This can be caused because the machine could not reach the host running the engine) 2. The eStore instance is using a different search schema that has data about the search engine host and is marked as stopped in that DB. To avoid this overrride \atg\search\routing\RoutingSystemService.properties by setting cleanUpStrayEng=false.
