Variables in Portlets

All,
I have small question, can we declare variable at class level ?


Generally in servlets we don't declare instance variables.

Is the samething applies to Portlets. I am little confused. Portlets are based on portletrequest & response, not on HttpRequest and HttpResponse.

Should we not declare instance variables for portlets ? Can someone who has clear understanding explain it.

I will really appreciate your help

Hi John,

Your understanding is correct - portlets are like servlets and you should not declare instance variables in the portlet class. The reason is the same as in case of servlets - multiple threads might be accessing the same portlet instance.
