org.apache.jasper.JasperException: Base is null

Please, I'm trying to open a copy of my project in another computer. I can't use CVS. When I try to execute my application I have the excepion listed on link http://www.aryjr.com/exception.html. In both machines, the Libraries in Library Manager are the same. Anybody can explain me what's happening?

Thanks!!!

See below, the line 177 is where the exception is raized on file index_jsp.java:

private boolean _jspx_meth_ui_page_0(javax.servlet.jsp.tagext.JspTag _jspx_th_f_view_0, PageContext _jspx_page_context)

throws Throwable {

PageContext pageContext = _jspx_page_context;

JspWriter out = _jspx_page_context.getOut();

// ui:page

com.sun.rave.web.ui.taglib.PageTag _jspx_th_ui_page_0 = (com.sun.rave.web.ui.taglib.PageTag) _jspx_tagPool_ui_page_id_binding.get(com.sun.rave.web.ui.taglib.PageTag.class);

_jspx_th_ui_page_0.setPageContext(_jspx_page_context);

_jspx_th_ui_page_0.setParent((javax.servlet.jsp.tagext.Tag) _jspx_th_f_view_0);

_jspx_th_ui_page_0.setId("page1");

_jspx_th_ui_page_0.setBinding("#{index.page1}");

int _jspx_eval_ui_page_0 = _jspx_th_ui_page_0.doStartTag(); // <<=== line 177

if (_jspx_eval_ui_page_0 != javax.servlet.jsp.tagext.Tag.SKIP_BODY) {

if (_jspx_meth_ui_html_0(_jspx_th_ui_page_0, _jspx_page_context))

return true;

}

if (_jspx_th_ui_page_0.doEndTag() == javax.servlet.jsp.tagext.Tag.SKIP_PAGE)

return true;

_jspx_tagPool_ui_page_id_binding.reuse(_jspx_th_ui_page_0);

return false;

}

I'm not understand.

Thanks!
