ATG EAR Creation

-
Basically two modes for EAR Creation, Development Mode and Standalone Mode,Main difference between these two is how the application access the Nucleus configuration information.For Development mode,the configuration information is accessed through the ATG installation and for other it takes from the EAR file.

Ant File

Application generally uses their own Ant build files to generate/create ATG EAR,it use  CreateUnpackedEarTask which uses clasees present inside assembler.jar.we can also use the runAssembler command directly.

runAssembler for development mode

runAssembler XXX.ear -m Modules.This will create the ear in the
exploded form which is generally used in our day to day development environment

runAssembler for standalone mode

runAssembler [-standalone] XXX.ear -m Modules.
This will create the ear in the  standalone form,which is used in production enviornment where you may not need an ATG installed platform to run the application.

Apart from the Modules specified explicitly through  the runAssembler or the Ant build files there are some other implicit modules which were created at the time of EAR generation -> ATG Implicit modules

Analysis This happens when the target/Production instance is down for some  reason or the RMI configuration which points to the target/Production instance may not be correct one. Fix If this is happening  due to target/Production instance down  then we can restart the target/Production Server,Other wise  correct the RMI configuration from the BCC agent configuration page and reinitialise. Verify the RMI Port in Configuration.properties file.Usually this file will be located in the path C:\ATG\ATG10.2\home\servers\ATGProduction\localconfig\atg\dynamo\Configuration...

Unable to access the selected application Exception in AppMerge flows progression Bean already exists "weblogic.j2ee.descriptor.ModuleBeanImpl@..../Modules[weblogic.descriptor.internal.Descriptor.Beankey@....] This issue can happen in many scenarios, may be you need to check your deployment descriptors based on Application Servers used, this generally happens due to issue in XML files related to deployment. I got this issue when i mistakenly added the modules twice in the Manifest file, the module 'Store.Storefront' is added more than once in  'ATG-Required'  of my Manifest.MF file,due to this i am seeing the module 'storedocroot.war' is added twice in my application.xml which is located in the  path ATGProd.ear\META-INF\application.xml.Due to this i am not able to deploy my EAR file.
