Question

Dear Friends,
TagLib how can I get the Attribute value (like JavaBean) in jsp .
I do this thing.
public void setPageContext(PageContext p) {
          pc = p;
pc.setAttribute("id", new String("1") );
          pc.setAttribute("first_name",new String("Siddharth")); //,pc.SESSION_SCOPE);
          pc.setAttribute("last_name", new String("singh"));
but in Jsp
<td>
<%=pageContext.getAttribute("first_name"); %>
cause null is returing.
Pls HELP me

First, there is no need to pass in the page context to the tag. It already is present. How you get to it depends on what type of tag:
Using [url http://java.sun.com/j2ee/1.4/docs/api/javax/servlet/jsp/tagext/SimpleTagSupport.html]SimpleTagSupport
public class MyTag extends SimpleTagSupport
  public void doTag()
    PageContext pc = (PageContext)getJspContext();
    pc.setAttribute("first_name", "Siddharth");
    pc.setAttribute("last_name", "Singh");
    pc.setAttribute("id", "1");
}Using [url http://java.sun.com/j2ee/1.4/docs/api/javax/servlet/jsp/tagext/TagSupport.html]TagSupport or it's subclass [url http://java.sun.com/j2ee/1.4/docs/api/javax/servlet/jsp/tagext/BodyTagSupport.html]BodyTagSupport the page context is aleady declared as an implicit object:
public class MyTag extends TagSupport
  public void doStartTag()
    pageContext.setAttribute("first_name", "Siddharth");
    pageContext.setAttribute("last_name", "Singh");
    pageContext.setAttribute("id", "1");
}In each case, this sort of thing should work:
<mytags:MyTag />
<%= pageContext.getAttribute("first_name") %>I
