java - How to access request in JspTags?

Question

I want to call request.getContextPath() inside a JSP tag which extends SimpleTagSupport, is there any way to do it?

Answer 1

First get the PageContext by the inherited SimpleTagSupport#getJspContext() and then get the HttpServletRequest by PageContext#getRequest().

PageContext pageContext = (PageContext) getJspContext();  
HttpServletRequest request = (HttpServletRequest) pageContext.getRequest();
