JSP and taglibs

romaz Jun 18, 2004 10:38 AM

Hi,

I'm developing a J2EE web application using JSP.
I'm interested in using taglibs for various operations. I'm using JBoss 3.2.4.
I just made a test using google-taglib (google-taglib.sf.net). I followed the instructions: placed taglib jar in /WEB-INF/lib and the .tld in /WEB-INF. Then I changed web.xml adding a taglib entry that points to the .tld.

I made a pretty simple page to check if all is fine:

<%@ taglib uri="/google-taglib" prefix="google" %>
<html>
<head>
<title>
 Test Page
</title>
</head>
<body>
<center><em>Copyright Â© 2004 by Romaz</em></center>
</body>
</html>

When I try to access my page http://localhost:8080/test/test.jsp I have this error:
exception

javax.servlet.ServletException: javax.servlet.jsp.tagext.TagAttributeInfo.(Ljava/lang/String;ZLjava/lang/String;ZZ)V
org.apache.jasper.servlet.JspServlet.service(JspServlet.java:244)
javax.servlet.http.HttpServlet.service(HttpServlet.java:853)

I've tried also some other taglib following the usual steps to get them working. I've always this error!

Thanks for answers, Romaz

Resolved:

I was using an erroneus version of javax.servlet.jar (the one I found on JBoss 3.2.3) because I didn't found it in JBoss 3.2.4. Only now I found that the new libraries were in servlet-api.jar and jsp-api.jar.

Thanks anyway
