cannot access javax.servlet.jsp.tagext.TagSupport

[new_2_java]

Hi all,

I am trying to compile the following class, but I keep getting this error message.

Class:

package com.tool;

public class WebTopBrowserTreeTag extends com.documentum.webtop.control.WebTopBrowserTreeTag
{
       protected Class getControlClass() {
             return com.tool.WebTopBrowserTree.class;
       }
}

Error:

com/tool/WebTopBrowserTreeTag.java:4: cannot access javax.servlet.jsp.tagext.TagSupport
file javax\servlet\jsp\tagext\TagSupport.class not found
public class WebTopBrowserTreeTag extends com.documentum.webtop.control.WebTopBrowserTreeTag
       ^
1 error

I also tried "import"ing the above package [javax.servlet.jsp.tagext.TagSupport] but still same error persists. Any suggestions/comment will be much appreciated.

Thanks.
