Hi friend,


<load-on-startup>1</load-on-startup>

Is it indicate order of servlet to be loaded or number of instances

Tha't the order in which the Servlet will be loaded by the container.

1 will be the first
2 will be the second


The <load-on-startup> element of a deployment descriptor is used to load a servlet file
when the server starts instead of waiting for the first request.
It is also used to specify the order in which the files are to be loaded.
The <load-on-startup> element is written in the deployment descriptor as follows:

<servlet>
<servlet-name>ServletName</servlet-name>
<servlet-class>ClassName</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>

Thanks
