ATG Search and how to generate XHTMLs from STG file


The ATG search  indexing will give you the idx and stg files. When I analyse the stg files with some text editors like Textpad or Ultraedit , found some <html> and </html> tags and the contents inside these tags seems to be the same content of the temporary XHTML files , which will be generated during the search indexing for each indexed item. So I deicded to take the contents in between the <html> and </html> tags and save as XHTML file and it works for almost all indexed items. As you might know, these XHTML file’s <head> tag contains all the meta properties ( refine properties ) and the <body> tag have the text properties ( searchable properties ) for each indexed item.

Please note that the above steps are not an ATG recommended method to generate the XHTML files. I come across to this simple method to form the XHTML files and I am not 100% sure that this will give all the XHTML files of a search index . But I found this to be very useful for debugging any ATG search related issues.

Please find the below JAVA code written to genrate the XHTML files from an stg file. The main method is expecting the name of the stg file as a program argument. This will create a folder named “XHTML_Files” in the current directory and will save the XHTML files inside this folder.

Please find the below screen shot of XHTML files generated using this JAVA code :




Please find the below screen shot of a sample XHTML file generated using this JAVA code :





import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;
import java.io.FileWriter;

public class ATGSearchStgXHTMLGenerator {
public static void main(String args[]) {
try {
String fileName =  args[0];
String xhtmlfilePath = ".\\XHTML_Files";
if(fileName ==  null){
System.out.println("Give the stg file name as input");
return;
}
File stgfile = new File(fileName);
FileReader stgfileFis = new FileReader(stgfile);
BufferedReader stgfileBr = new BufferedReader(stgfileFis);
String readLine = stgfileBr.readLine();
String outToWrite = null;
String outFileName = null;
File outFile = new File(xhtmlfilePath);
boolean exists = outFile.exists();
if(!exists){
(new File(xhtmlfilePath)).mkdir();
}
FileWriter outFileWriter = null;
int lineNumber = 1;
int xhtmlFileCount = 1;
boolean canWriteXhtmlfile = false;
do {
if(readLine.contains("<html>")
&& readLine.contains("</html>")){
outToWrite = readLine.substring(readLine.indexOf("<html>"),readLine.indexOf("</html>")+7);
outFileName = "\\XHTMLFile_";
canWriteXhtmlfile = true;
}else if(readLine.contains("<html>")
&& !readLine.contains("</html>")){
System.out.println("In the STG file at lineNumber:" +lineNumber+" ERROR: html tag found, but no end tag for");
outToWrite = readLine.substring(readLine.indexOf("<html>"),readLine.length());
outFileName = "\\XHTMLFile_Error_";
canWriteXhtmlfile = true;
}
if(canWriteXhtmlfile){
outFile =  new File(xhtmlfilePath+outFileName+(xhtmlFileCount++)+".xhtml");
outFileWriter =  new FileWriter(outFile);
outFileWriter.write(outToWrite);
outFileWriter.close();
}
readLine = stgfileBr.readLine();
lineNumber++;
canWriteXhtmlfile = false;
} while (readLine != null);
System.out.println("The STG file is processed fully till lineNumber"+lineNumber);
} catch (Exception e) {
e.printStackTrace();
}
}
}

ATG - basic concepts of ATG

This blog is for the ATG beginners to get some basic overview about ATG. I just given the ATG concepts as a list of numbered points for the ease of understanding. 1. At the framework level, ATG is a               java based application platform for hosting web-based applications, as well as RMI accessible business components,               with an ORM layer,               a component container,               an MVC framework,               and a set of tag libraries for JSP. 2. Art Technology Group(ATG)'s Dynamo Application Server (DAS) is a Java EE compliant application server. DAS is no longer actively developed as ATG recommends using other Java EE applications servers for its products such as BEA WebLogic, JBoss or IBM WebSphere. 3. Prior to ATG 2007, JHTML was used instead of JSP for view purpose. J...

ATG Search - how to configure multiple language search

Here I am going to explain the steps involved in configuring the multi-language ATG Search if your site support multiple language. I have given the different steps in indexing and search flows. Indexing flow : You could configure different search projects for different locales to support parallel search indexing for each locale. You could setup search environment for the search projects so that the indexing host is different for the two projects. Configure the LocaleVariantProducer @ ProductCatalogOutputConfig to specify the locale for the new language. Include the language dictionaries you need in Search Admin on the Search Projects which can be used for indexing and searching in multiple languages. Specify the locales @ \atg\search\config\LanguageDimensionService so that you could configure the search configurations for each language. When you create the search configuration tree, specify the "Contents vary by" as Language, to configure the search configurations li...

ATG search installation and search engine log files

Here I would like to explain how your ATG search folder structure looks like after you do the ATG search installation and also about the search engine log files. To get the ATG search, you need to install the ATGSearch<version>Windows.exe after you do the ATG installation. When you install ATG search, the generated folders include an OS dependant folder. In the below screen shot, you could see the "i686-win32-vc71" folder and this is generated since the ATG search ins installed in a windows machine. The ATG search engine is actually an exe file inside this "i686-win32-vc71" folder. Below screen shot give you an idea about the "atgsearch.exe", which is the search engine application. This search engine application (atgsearch.exe) is started by a remote launcher call from the BCC search administration UI.  The log files like "atgsearch_20120106112413_568.log" are the search engine log files where you could see the engine ...

ATG Search and startRemoteLauncher

If the search engine application is running in a separate box than the ATG CA-BCC deployed server, the search engine is invoked through a remoteLauncher running in these boxes. Means, a remoteLauncher needs to run in the host where SearchEngine is installed remotely to start the search engine. You could find the startRemoteLauncher.sh @ ATG/ATG2007.1/Search2007.1/SearchAdmin/bin/startRemoteLauncher.sh Start remoteLauncher using the command   ./startremotelauncher.sh –p <RMI Launcher service Port > & The Launcher Service Port on the host machine can be found in BCC @ Search Administration>Projects > Search Project: gmri_search_en_CA > Environments > Host Machine: > Advanced Settings. If the startRemoteLanucher reports a BindingException , then you need to find the process that is using the launchServicePort. For that run the netstat command like :   netstat -an |grep 10880 Then inorder to identify the process t...
