Why we need to implement Single Thread model in case of Servlet.

In J2EE we can implement our servlet on two different ways either by using:
1. Single Thread Model
2. Multithread Model
Depending upon our scenario, if we have implemented single thread means only one instance is going handle one request at a time no two thread will concurrently execute service method of servlet.
Example in banking account where sensitive data is handle mostly this scenario was used this interface is deprecated in Servlet API version 2.4.

As the name signifies multi thread means a servlet is capable to handle multiple requests at same time. This servlet interview question was quite popular few years back on entry level but now its loosing its shine.

Can we call destroy() method inside the init() method is yes what will happen?

Yes we can call like this but  if we have not override this method container will call the default method and nothing will happen.after calling this if any we have override the method then the code written inside is executed.

Why super.init (config) wiil be the first statement inside init(config) method.

This will be the first statement if we are overriding the init(config ) method by this way we will store the config object for future reference and we can use by getServletConfig ()  to get information about config object if will not do this config object will be lost and we have only one way to get config object because servlet pass config object only in init method . Without doing this if we call the servletConfig method will get NullPointerException.

For initializing a servlet can we use constructor in place of init ().

No, we can not use constructor for initializing a servlet because for initialization we need an object of servletConfig using this object we get all the parameter which are defined in deployment descriptor for initializing a servlet and in servlet class we have only default constructor according to older version of java so if we want to pass a
Config object we don’t have parametrized constructor and apart from this servlet is loaded and initialized by container so ots a job of container to call the method according to servlet specification they have lifecycle method so init() method is called firstly.

More important Java doesn't allow interfaces to declare constructors. These kinds of servlet interview questions are quite popular on service based companies who just want to dig one level more.

How can we create deadlock condition on our servlet?

one simple way to call doPost() method inside doGet() and doGet()method inside doPost() it will create deadlock situation for a servlet. This is rather simple servlet interview questions but yet tricky if you don’t think of it J

In web.xml file <load-on-startup>1</load-on-startup> is defined between <servlet></servlet> tag what does it means.

whenever we request for any servlet the servlet container will initialize the servlet and load it which is defined in our config file called web.xml by default it will not initialize when our context is loaded .defining like this <load-on-startup>1</load-on-startup> is also known as pre initialization of servlet means now the servlet for which we have define this tag has been initialized in starting when context is loaded before getting any request.When this servlet question was asked to me in an interview few years back , I was not even aware of this element but this questions pointed me to look DTD of web.xml and understand other elements as well..
