Configure web.xml

First, add the jar files to your web application (one place you can put them is in WEB-INF/lib). Next, configure your web.xml file to load the servlet. To do this, add the following to your web.xml:
<servlet> 
    <servlet-name>Orb</servlet-name> 
    <display-name>JsOrb Servlet</display-name> 
    <servlet-class>org.jsorb.servlet.Orb</servlet-class> 
    <load-on-startup>1000</load-on-startup> 
</servlet> 

<servlet-mapping> 
    <servlet-name>Orb</servlet-name> 
    <url-pattern>/jsorb/*</url-pattern> 
</servlet-mapping>
The above will load the JsOrb servlet and map it to /jsorb. and tell JsOrb where you mapped it. Last, configure the TLD in your web.xml file.
