Eclipse Luna - Good features of Eclipse 4.4 JDT / Workbench

Split editors

Do you ever find yourself working in a large file and need to view or edit multiple sections at once ? You can now split / unsplit the currently active editor. Use quick access and type split to get different options.

Dark theme

A new dark window theme has been introduced. You can enable it from the General > Appearance preference page.

Show In System Explorer

If you select a resource and right click, there is now a Show In>System Explorer context menu entry that will open the folder containing that resource in your system's file explorer.

New layout for minimized views

Minimized views can have a different display mode by right-click on the "Restore" button of a minimized stack and select the "Show in the Original Location" menu item.

Filter conflicting projects during import

When importing existing projects, you can now filter out any conflicting projects (projects that are already present in your workspace).

Quick Fixes to create 'for' loops

A set of new quick fixes can create for loops that iterate over a given expression for arrays, Collections and Lists

Enabled coloring of variables

Parameter variables and local variables are now colored by default. You can change it @ Java > Editor > Syntax Coloring preference page.

Java 8 Support

The Eclipse compiler for Java (ECJ) implements all the new Java 8 language enhancements.

Improved Hot Code Replace for member types

Hot Code Replace has been improved in the Java debugger to ensure the correct method is dropped to in member types (inner / anonymous / local classes).

Search Facets - how to create a new search facets in ATG Search

A Facet is a search refinement element that corresponds to a property of a commerce item type. ATG supports the search result refinement using the Faceted Search concept. Read more about facted search @ http://en.wikipedia.org/wiki/Faceted_search . Facet can either be ranges or specific values. Each facet is stored in the RefinementRepository as a separate refineElement repository item. Facets are divided into Global and Local facets. Global facets apply to all the categories and local facets only to the category in which they are created. For example Price/Brand can be considered as the facets that are common for all skus and New Release/Coming Soon can be considered as the facets that are specific to Physical Media products like Vidoe/DVD/Blue-ray/Books. We can use the ATG BCC - Merchandising UI to create facets. The Faceting Property depends on the meta-properties defined in the \atg\commerce\search\product-catalog-output-config.xml ( the def...

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...

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 - how to prevent Cross-Site attacks using _dynSessConf parameter

Cross-site scripting attacks take advantage of a vulnerability that enables a malicious site to use your browser to submit form requests to another site. In order to protect forms from cross-site attacks in ATG, you can enable form submissions to automatically supply the request parameter _dynSessConf , which identifies the current session through a randomly generated long number. On submission of a form (using dsp:form tag) or activation of a property setting (using dsp:a tag), the request-handling pipeline ( DAFDropletEventServlet ) validates _dynSessConf against its session confirmation identifier. If it detects a mismatch or missing number, it can block form processing and return an error. To disable this functionality, we could give the following properties (@ /atg/dynamo/Configuration to disable it globally) enforceSessionConfirmation = false --> specifies whether the request-handling pipeline requires session confirmation in order to proc...

Lucene, sample JAVA code to Search an indexed file folder

Please find below the Lucene sample JAVA code to search the files inside a folder. This code will search the indexed folder for a search query in an indexed field. This java code is expecting the index path ( where the index files were created ) , field which need to be searched and the query need be searched as program arguments like "java SearchFiles [-index dir] [-field f] [-query string]" . import java.io.File; import java.util.ArrayList; import org.apache.lucene.analysis.Analyzer; import org.apache.lucene.analysis.standard.StandardAnalyzer; import org.apache.lucene.document.Document; import org.apache.lucene.queryParser.QueryParser; import org.apache.lucene.search.IndexSearcher; import org.apache.lucene.search.Query; import org.apache.lucene.search.ScoreDoc; import org.apache.lucene.search.TopDocs; import org.apache.lucene.store.FSDirectory; import org.apache.lucene.util.Version; public class SearchFiles { public static void main(Stri...
