The error message tells you there's a problem in index.jsp.
Check the line indicated in the error message, or post the code here.

i know what the problem is ? i was trying to assign a variable to the value parameter in the <jsp:setProperty>.
i just want to know that, is there any method by which we can set the property dog here using <jsp:setProperty> inside <jsp:useBean>
or setting value like this is valid for only string type properties.

Hi Avi. Here 'value' attribute not only used for strings. We can also use jsp expressions, EL.
