The servlet above is created using Netbeans. Assuming you have already added the iText library to your project, right click on 

your project name and select New and then servlet then follow the screen. A servlet will be created. If you created your 

servlet with a name "Pdf" you can directly copy the whole class above and replace the entire servlet you just created and 

replace the package name to your actual package name. If you have choosen another name, you need to change the name of the 

servlet above and the package name. 


 A corresponding entry into your web.xml file should have been created when you created your servlet. It should look like 

below.



<pre name="code" class="xml">
 

 &lt;servlet>
 &lt;servlet-name>Pdf&lt;/servlet-name>
 &lt;servlet-class>your-package.Pdf&lt;/servlet-class>
 &lt;/servlet>

 &lt;servlet-mapping>
 &lt;servlet-name>Pdf&lt;/servlet-name>
 &lt;url-pattern>/Pdf&lt;/url-pattern>
 &lt;/servlet-mapping>
 
 
 
 
</pre>



Your html or JSF page that calls the servlet should look like below.



<pre name="code" class="xml">
 
 &lt;a href="/demo/Pdf">Generate&lt;/a>

 &lt;!-- or -->

 &lt;h:outputLink value="/demo/Pdf">
 &lt;h:outputText value="Generate PDF" />
 &lt;/h:outputLink>
 
 
 
</pre>





Please refer to the inline comments for information on using items in the servlet. For more information on using iText visit 

the iText documentation page <a href="http://itextpdf.com/book/toc.php" target="_blank" class="news_link" title="iText 

documentation">here</a>.



Good luck.
