I am trying to write a custom taglib that extends the TagSupport class.
At one point my implementation worked, but when upgrading to Tomcat
4.0.4, I keep getting a NullPointerException because the protected
variable pageContext is null.
Any clues? Is tomcat's servlet implementation no longer setting the
PageContext? What gives? Or how do I get a handle to the request and/or
response context so that I can get and put attributes and write output
to the browser?
Here is my code BTW:
JSP:
-------------------------------------------------------------------------
<otg:getCity id="city"
cityId="/world/south_america/bolivia/cobija_city"/>
<p>City Name: <jsp:getProperty name="city" property="name"/></p>
CLASS:
-------------------------------------------------------------------------
public class GetCityTag extends TagSupport {
/* blah blah blah */
public int doEndTag()
throws JspException
{
City city = (City)getCity(getCityId());
/* this next line is where the NullPointerException occurs */
pageContext.setAttribute(getId(), city);
/* ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ */
try {
pageContext.getOut().write("City id is " + cityId + "!");
pageContext.getOut().write("Storing fetched city
'"+city.getName()+
"' as " + id + "!");
} catch(IOException e) {
throw new JspTagException("An IOException occurred.");
}
return EVAL_PAGE;
}
}
