What is the difference between ServletContext and ServletActionContext

Question

Please tell me what is the difference between ServletActionContext and ServletContext? ServletContext is shared among all the servlets and actions, while ServletActionContext is specific to an action or is that also shared among all the actions?

ServletActionContext is not part of standard JSP/Servlet specs , it is provided by Struts, it provides a way to access to web objects like servlet parameters, request attributes and things like the HTTP session. – Bouldon

thanks for the reply. But I want to know whether ServletActionContext is shared by all the actions or specific to an action – Taal

Answer 1

These are different things. ServletContext is a servlet related, ActionContext is Struts 2 action related, ServletActionContext extends ActionContext but in major it's an utility class.

If you want to know what is the actioncontext.

Thanks. I have another doubt, Is ServletActionCotext shared by all actions or is that specific to one action? – Taal

@Taal I don't understand your question, ActionContext is created per action, and it's threadlocal, means not accessible by other actions/threads. – Muenster

Answer 2

ServletConfig Object:

• It is ONE per our Servlet class object
• Servlet container creates this either during server startup or during the deployment of web app based on Servlet configuration done in web-xml file
• It is the object of servlet container supplied java class that impleents java.servlet.ServletCongfig(I).
