ATG Customize and Enhance your CRS Module easily

-
Firstly we need to create a folder and give the name of your choice,For example i have given Wirelessstore, inside that folder you create a META-INF folder,and create a MANIFEST.MF file,once this is done then modify the Manifest file property to ATG-Install-Unit:MyWirelessStore(MyWirelessStore is the name i have given instead of the name Store in CRS module) and create a folder with the same name MyWirelessStore under Wirelessstore,after this copy all  CRS-Store folders under this folder.

You can Refer the CommerceReferenceStore Manifest file for this.

Now configure your eclipse and import the necessary folders to your workspace.Resolve the classpath by importing required Jars and Classes to your Buildpath and do a clean build of your Project.

Now create a runAssembler command so that it will pick modules from your newly created folder structure.

runAssembler -m ATGProduction.ear -m DafEar.Admin DPS DSS  DSS DCS.PublishingAgent MyWirelessStore.EStore MyWirelessStore.Recommendations MyWirelessStore.Storefront.NoPublishing    MyWirelessStore.Fulfillment

so now you have the ATGProduction.ear ready to deploy in your Application Server.Deploy it and run the Server with correct datasources you can see the CRS running exactly same way similiar to the one installed through CIM or other ways.

Now modify your JSPs,Java,Components and do a clean build and deploy your changes will appear in the CRS Application.

Similiarly create a runAssembler for the Publishing modules and do the necessary configurations in BCC and do a full deployment.


Issues Faced during creation of CRS Module

If you are customising the CRS Module you need to take care of the reference to absolute path of certain components,one such issue i faced is the application is not able to find the exact keystore location.This happens even adding an item to Cart and further flows.

the keystore location is mentioned in the component /atg/store/security/crypto/SecretKeyStoreManager  with the property 'file'.You need to modify the entry so that it will point to your modified structure.

The actual entry in CRS will be like
file = {appModuleResource?moduleID=Store.EStore&resourceURI=keystore/store-crypto.jks} ,you have to modify this so that it point to MyWirelessStore.

For example in my application the absolute path will be C:\ATG\ATG10.2\Wirelessstore\MyWirelessStore\EStore\keystore\store-crypto.jks

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...

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>  ...

Add a shopping cart button to the product page

Make sure you have ATG running with your Application  module. We are adding a jsp page fragment called addcart.jsp . This fragment will use two parameters passed from other jsp, skuInfo.jsp - skuId and productId . Add the form and inputs required to add an item to the order,  as shown in the sample code below: <dsp:input type="hidden" bean="CartModifierFormHandler.catalogRefIds" paramvalue="skuId"/> <dsp:input type="hidden" bean="CartModifierFormHandler.productId" paramvalue="productId"/> <dsp:input type="text" size="5" bean="CartModifierFormHandler.quantity" value="1"/> <dsp:input type="hidden" bean="CartModifierFormHandler.addItemToOrderSuccessURL" value="cart.jsp"/> <dsp:input type="submit" bean="CartModifierFormHandler.addItemToOrder" value="Add to Cart"/> Don't forget to import the /at...
