If i return invalid integer value from doStartTag() in following code,no exception occurs,which is understandable since return type of doStartTag() is integer.But what i got as output is as if EVAL_BODY_INCLUDE (which is equal to 1)is returned.
The out put is as follows:
in doStartTag with 23(invalid) return value This is tag body which can be jsp -----in doAfterBody-----in doEndTag Is it container specific behaviour ( I am using Tomcat )or is it what jsp spec says?
Even if i return other values like SKIP_PAGE (which is valid for doEndTag()), i got same output as above.
If i returned invalid integer from doAfterBody(),it behaved as if SKIP_BODY is returned.
Returning invalid integer from doEndTag() gave output as if EVAL_PAGE is returned.
These are default return values unlike EVAL_BODY_INCLUDE in case of doStartTag().
If such a question comes in exam(although probability is low),should the answer be "container dependent"
Make sure that we should not return the value '0'(which is default return value of SKIP_BODY) in doStartTag(). If we return, the body will not be evaluated. Tomcat will checks that condition.
Tomcat is not performing may conditional checks incase of ClassicTags. If they performs, if affect on performance.
