Configuring Apace Server to run PERL scripts

Follow following steps to run PERL script on Apace Server


Step 1: 
Open <APACHE_HOME>/conf/httpd.conf file


httpd.conf - is the main configuration file for Apache HTTP Server


Step 2: 
Search for "ScriptAlias /cgi-bin/" uncomment i.e. remove '#' if commented. You may need to adjust the path to run your script successfully


ScriptAlias - Provides the location for CGI programs. This should be two parts, separated by whitespace. The first part is the part used in URL that triggers execution of a CGI program; the second part is the path where those CGI programs are stored in the real filesystem


Step 3:
Search for "AddHandler cgi-script" in the document, uncomment it, if committed and append ".pl " after ".cgi"


Step 4: 
Modify your PERL Script. If your script is Windows executable it does't means that it will run on Apache Server as well 'coz script relies on PERL interpreter, so we have to modify the hashbang or the shebang or  the first line of your script. Append perl.exe (For Windows only)


Step 5: 
The line after shebang line should define the MIME-type header.


print "Content-type: text/html; charset=iso-8859-1\n\n"; 


Now you are all set to run your first CGI program. Just open your browser and access http://localhost/cgi-bin/helloWorld.pl


NOTE: helloWorld.pl is the name of the PERL file I created it can be different in your case.

Custom PagingNavigator for SEO friendly URL

Apache Wickets biggest strength is its focus on  components  - Among a very large set of components is PagingNavigator component. It is a Wicket Panel component to draw and maintain a complete page navigation. I found this component very useful but the only problem that compelled me to write my own CustomPagingNavigator is the wicket URLs that are being created by clicking the page links.  The Java Part... public class CustomPaginationLinksPanel<T> extends Panel{   private static final long serialVersionUID = 10002L;   /** Pageable List View to be displayed  */   private PageableListView<T> mainView ;   /** Max count of links  default  value = 5 */   private int linksPerPage = 5;   /**  Page Number currently visible */   private int    currPgNum ;     /** first page number */   private int firstNum ;   /** last page number */   private int lastNum ;   //Calculated on the basic of List size   private int maxPages ;

The Externalizable Interface

Before you start exploring Externalization in Java, I would recommend you to gather some knowledge of Serialization in Java because Externalizable is an alternative to Serializable interface. Externalizable interface allows you to customize how serialization is done. By implementing Externalizable you are controlling what gets serialized and what does not get serialized.  Externalizable interface  extends Serializable interface and defines two methods to be overridden by the implementing class.  public void readExternal(ObjectInput in) throws IOException, ClassNotFoundException public void writeExternal(ObjectOutput out) throws IOException Java class implementing Externalizable interface package learn.java.serialization; import java.io.Externalizable; import   java.io.IOException; import   java.io.ObjectInput; import   java.io.ObjectOutput; import   java.util.Date; public class ExternalizableObject implements Externalizable {    private String name;    private
