你好。。信息: At least one JAR was scanned for TLDs yet contained no TLDs. Enable debug logging for this logger for a complete list of JARs that were scanned but no TLDs were found in them. Skipping unneeded JARs during scanning can improve startup time and JSP compilation time这个是错误吗。。点了没反应
SUCCESS和ERROR吧?
如果你让其返回值
return null;
然后你写入到返回流中的信息就可以返回给页面了。。
</action>
不是很懂。但是本来方法是这个public void CheckUsername() throws Exception{
HttpServletResponse response = ServletActionContext.getResponse();
if(ms.checkUsername(getUsername())>0){
response.getWriter().write("1");
}else {
response.getWriter().write("0");
}
response.getWriter().close();
} 貌似不需要返回值的。。
不是很行、、、没反应。。开了tomacat 点击没反应。
不是很行、、、没反应。。开了tomacat 点击没反应。要有啥反应?
这样写之后看一下有没有执行这个action
如果执行了action,再看一下页面取没取到值,页面取到值就ok了,
这样写页面又不会跳转.

return null;应该就可以。
