導入功能在活動服務器上正常工作，但在Java中不在本地主機

我在點擊網頁上的導入按鈕時得到了這個堆棧跟蹤，它在活動服務器上工作正常，但在Java中不在本地主機上，它是否可用本地主機配置問題？導入功能在活動服務器上正常工作，但在Java中不在本地主機

這裏是代碼：

public void doFilter(
    ServletRequest req, 
    ServletResponse resp, 
    FilterChain chain) 
    throws ServletException, IOException { 

    HttpServletRequest request = (HttpServletRequest) req; 
    HttpServletResponse response = (HttpServletResponse) resp; 
    request.setAttribute(TapestryFilter.REGISTRY_CONTEXT_NAME, servletContext.getAttribute(TapestryFilter.REGISTRY_CONTEXT_NAME)); 
    //for multi-charset support 
    request.setCharacterEncoding("utf-8"); 

    UserToken userToken = (UserToken) request.getSession().getAttribute(WebKeys.USER_TOKEN); 
    //check user authorization 
    if (userToken == null || request.getParameter(LOGIN_TEST_BUTTON)!=null) { 
    //not coming inside if block 
    //code of if block 
    } 
    else { 
     chain.doFilter(req, resp);//Error in this line 192 
    ConnectionTracker.logUnclosedConnectionErrors(request.getPathInfo()); 
    } 
}

哪個是您的過濾器中的第192行？ –

我已經對該行給出了評論，它在其他部分：chain.doFilter（req，resp）; //（AuthenticationFilter.java:192） – user1933980
