Hello,
I'm trying to use a custom Taglib in the JSP file of a Portal Component. Therefore I created a reference in the JSP via <%@ taglib uri="/PORTAL-INF/taglib/helloWorldTag.tld" prefix="hello" %> . The tld file is located in the folder /PORTAL-INF/taglib/ and is named helloWorldTag.tld.
I always get the error com.sapportals.portal.prt.servlets_jsp.server.jsp.ParseException: Error in parsing taglib '/PORTAL-INF/taglib/helloWorldTag.tld' tag in web.xml or .tld file of the taglib library.
Can anybody tell what I am missing?
Thanks and best regards
Dominik
Look in below link...
I think you have made some mistake in mapping of your TLD in Web.xml....

Hi Saurabh,
thanks for thetutorial.
I think I am one step further but I encounter a strange behaviour now:
When I implement all steps as described in the tutorial, I get the following error message:
04:41_14/06/11_0022_4093353
[EXCEPTION]

But when I comment all lines in the doStartTag() method like this
public int doStartTag() throws JspException {
// try {
// Locale locale = pageContext.getRequest().getLocale();
// String sOutput = sayHello(locale);
// pageContext.getOut().write("<BR>" + sOutput);
// Calendar cal = Calendar.getInstance(locale);
// pageContext.getOut().write(
// "<BR> Server Time is - " + cal.getTime());
// } catch (Exception ex) {
// throw new JspException("Error:" + ex);
// }
return EVAL_PAGE;
}
the JSP page compiles and I see a blank screen (as expected).
I am not sure about the step in the tutorial, where I should add the Servlet.jar to the project classpath. I added the j2ee-1.4.jar to the lib folder of the project.If I just but the JAR to the build path I get a java.lang.NoClassDefFoundError: javax/servlet/jsp/JspContext Exception. Maybe here is something is wrong?
Any further ideas?
Thanks and best regards,
Dominik
Hi,
my bad. I took the servlet.jar from the server. This turned it tight.
Thanks again and best regards,
Dominik
