You are seeing this page because development mode is enabled. Development mode, or devMode, enables extra debugging behaviors and reports to assist developers. To disable this mode, set: 

  struts.devMode=false

in your WEB-INF/classes/struts.properties file.

@Override
protected String getSolution() {
//System.out.println("......................."+getConfig().getSolution(getSysType()));
// 针对禁止文章找不到模板方案的情况。
String st=getSysType();
if(st==null)st="cms_member";
return getConfig().getSolution(st);
}

不知道这个修改合适不？
