ATG Component dos and donts

-

Try to keep Class and Component name same if possible(keeping in mind that one java class may be the source of multiple components).Also try to match Component path with class package structure if class is not an ATG component extension.


Always pass request and session scope objects to global scope component methods instead of resolve component.


Use window scope when you want different browser windows to maintain different states (another way to do that is to use URL parameters—for example, if a user wants to view two different products in separate windows—however, sometimes URL parameters are not sufficient or convenient).


ATG support Window scope which allows you to associate specific component instances with a specific browser window. Such components need to live longer than a request and also need to be different for every browser window associated with the user’s session.


Global component should not refer any session/request scope component.


Session component should not refer any request scope component.


Global scope component should not have any class level member variable.

The Error Message showing in BCC T he error logs is showing the below message /atg/epub/DeploymentServer Failed to connect to agent 'Production'. This agent not allowed to be absent for  a deployment. The server will continue attempts to  intialize the connection. Set loggingDebug to true for  continued exception and stacktrace logging. 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.properties,make sure the

Weblogic Issues during EAR Deployment Exception in AppMerge flows progression

-
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. I have removed the duplicate entry and deployed the application and everything working fine. ....... <module>         <web>             <web-uri>atg_

DUseSunHttpHandler=true weblogic.net.http.SOAPHttpsURLConnection Weblogic/Java HttpHandler issues

-
Verify the issue is happening due to the error throwing  from the weblogic class  SOAPHttpsURLConnection,then you need to inform the Application Server which handler implementation you need to use.  add the following option to JAVA_OPTIONS in   setDomainEnv.sh/setDomainEnv.cmd  on Unix/Windows.   -DUseSunHttpHandler=true.  eg:  set JAVA_PROPERTIES=%JAVA_PROPERTIES% %WLP_JAVA_PROPERTIES%  set JAVA_OPTIONS=%JAVA_OPTIONS% %JAVA_PROPERTIES% -  DUseSunHttpHandler=true -Dwlw.iterativeDev=%iterativeDevFlag% -  Dwlw.testConsole=%testConsoleFlag% -Dwlw.logErrorsToConsole=%  logErrorsToConsoleFlag%  This setting tells WebLogic to use the Sun's https Handler   implementation rather than the WebLogic one.  So after this,it will use the  class HttpsURLConnection from the  javax package.   See Also   SSL Handshake error   java.lang.RuntimePermission modifyThread
