我的login页面出现了这样的一个错
org.apache.jasper.JasperException: /WEB-INF/jsp/common/general/LogIn.jsp(34,5) Unable to load tag handler class "com.ils.tag.ExTextTag" for tag "html:text"

note The full stack trace of the root cause is available in the Tomcat logs.我在原来系统中com.ils.tag.ExTextTag改成了com.gjp.tag.ExTextTag,但不知在那里设置这个tag handler class ,向大家急求助。我就把包的名字改了一下，自定义标这就出错了，

正确情况下login页面的编译后的代码
private boolean _jspx_meth_html_text_0(javax.servlet.jsp.tagext.JspTag _jspx_th_html_form_0, PageContext pageContext)
          throws Throwable {
    JspWriter out = pageContext.getOut();
    //  html:text
    com.ils.tag.ExTextTag _jspx_th_html_text_0 = (com.ils.tag.ExTextTag) _jspx_tagPool_html_text_style_property_onchange.get(com.ils.tag.ExTextTag.class);
    _jspx_th_html_text_0.setPageContext(pageContext);
    _jspx_th_html_text_0.setParent((javax.servlet.jsp.tagext.Tag) _jspx_th_html_form_0);
    _jspx_th_html_text_0.setProperty("uid");
    _jspx_th_html_text_0.setStyle("width:120");
    _jspx_th_html_text_0.setOnchange("document.all.pid.value=this.value");
    int _jspx_eval_html_text_0 = _jspx_th_html_text_0.doStartTag();
    if (_jspx_th_html_text_0.doEndTag() == javax.servlet.jsp.tagext.Tag.SKIP_PAGE)
      return true;
    _jspx_tagPool_html_text_style_property_onchange.reuse(_jspx_th_html_text_0);
    return false;
  }问一下，如果我要改包名，这个地方在那里改，在那里可以改掉这个路径？
