ATG - more about Forms and Form Handlers

An ATG form is defined by the dsp:form tag, which typically encloses DSP tags that specify form elements, such as dsp:input that provide direct access to Nucleus component properties. Find below a sample dsp:form tag.    <dsp:form action="/testPages/showPersonProperties.jsp" method="post" target="_top">      <p>Name: <dsp:input bean="/samples/Person.name" type="text"/>      <p>Age: <dsp:input bean="/samples/Person.age" type="text" value="30"/>      <p><dsp:input type="submit" bean="/samples/Person.submit"/> value="Click to submit"/>    </dsp:form>   When the user submits the form, the /samples/Person.name property is set to the value entered in the input field.Unlike standard HTML, which requires the name attribute for most input tags; the name attribute is optional for DSP form element tags. If an input tag omits the n...

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...
