Place your code in doStartTag as it can return SKIP_BODY to exclude body from
resulting HTML.
return EVAL_BODY_INCLUDE if you want the body to be included

> Hi,

> I am writing a custom tag: MyLinkTag that extends the

> MyLinkTag has two fields. They are

> The functionality of the MyLinkTag is captured in the following code

> ****************************************************************************
> *******
> HttpServletRequest request = pageContext.getRequest();
> ActionMappings actionMappings =
> (ActionMappings)request.getAttribute(Action.MAPPINGS_KEY);
> String path = getHref();
> ActionMapping actionMapping = actionMappings.findMapping(path);
> String[] roleNames = actionMapping.getRoleNames();
> boolean userInRole = false;
> for(int i=0; i<roleNames.length(); i++)
> {
> userInRole = request.isUserInRole(roleNames);
> if(!userInRole){
> if((alternateLink != null) && !("".equals(alternateLink))){
> setHref(alternateLink);

> else{
> if(showAlways){

> The problem is I don't know where to place this code i.e. in which method:
> doStartTag() or doEndTag() or doAfterBody() or any other??
> What method should I override??
> And what should be the return [integer] values??
