Org.apache.commons.codec.DecoderException - htmlunit.WebClient

Galera, sou novato em desenvolvimento web com java e estou tendo um probleminha aqui…

String url = request.getParameter("url");
if (url != null) {

                String urlPagina = url;

                 WebClient webClient = new WebClient();
                 webClient.getBrowserVersion().setBrowserLanguage("pt-br");
                        
                  try {
                        HtmlPage page1 = webClient.getPage(urlPagina);
                        StringBuilder conteudo = new StringBuilder(page1.asXml());
                        out.print(conteudo);
                  } catch (Exception e) {
                        out.print(e.getMessage());
                  }
} else {
     out.print("Variável url não recebida... <br/>");
}

porém, quando eu executo o projeto, me deparo com o seguinte erro:

org.apache.jasper.JasperException: An exception occurred processing JSP page /index.jsp at line 41

OBS: realizei alguns imports, e não sei se é isso que está gerando excessão

<%<a class="mention" href="/u/page">@page</a> import=“com.gargoylesoftware.htmlunit.html.HtmlPage”%>

<%<a class="mention" href="/u/page">@page</a> import=“com.gargoylesoftware.htmlunit.WebClient”%>

<%<a class="mention" href="/u/page">@page</a> import=“com.gargoylesoftware.htmlunit.BrowserVersion”%>

<%<a class="mention" href="/u/page">@page</a> import=“java.net.URL”%>

<%<a class="mention" href="/u/page">@page</a> import=“java.util.ArrayList”%>

E ae pessoal, alguém tem idéia do que pode ser? Valeu
