  1. TagSupport Vs BodyTagSupport ....usage. (1 messages)

    WHAT IS THE DIFFERENCES BETWEEN TagSupport and BodyTagSupport. and when to use eath of them give alll possible differences
  2. A BodyTag can manipulate its body, using its BodyContent object, while a normal Tag cannot. BodyTags are useful when you want to use or transform the contents of the tag.

    For example, suppose you want to have a <cust:param> tag that sets parameter values using the tag body:

    <cus:param name="[param-name]">[param-value]</cust:param>

    This would have to be implemented as a BodyTag, which could get the tag contents (and the parameter value) as follows:

    public int doAfterBody() {
        String paramValue = bodyContent.getString();
        // More logic ...
    }
