Hi,
I want to display the body value of JSP in custom tag name Simple from the tag handler by extending the class, BodyTagSupport, but getting a runtime exception ;o)
The JSP code is:
<html><body>
<%@ taglib prefix="mine" uri="simpleTags" %>
Advisor page
<mine:simple>
Balle Balle
</mine:simple>
</html></body>
and the Tag handler class is:
package foo;
import java.io.*;
import javax.servlet.jsp.*;
import javax.servlet.jsp.tagext.*;
public class SelectTagHandler extends BodyTagSupport
{
public int doStartTag() throws JspException{
return EVAL_BODY_BUFFERED;
}
public int EndTag()
{
try{
pageContext.getOut().print(bodyContent);
}
catch(Exception e)
{
}
return EVAL_PAGE;
}
and the exception, which I'm getting is:
type Exception report
message
description The server encountered an internal error () that prevented it from fulfilling this request.

note The full stack trace of the root cause is available in the Apache Tomcat/5.5.27 logs.
Edit: The code of my TLD file is:
<taglib xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee/web-jsptaglibrary_2_0.xsd" version="2.0">

<uri>simpleTags</uri>
<tag>
<name>simple</name>
<tag-class>foo.SelectTagHandler</tag-class>
<body-content>scriptless</body-content>
</tag>
</taglib>
What's wrong I'm doing here?
