　　最近在弄SSO，准备用CAS认证，教程上用的是tomcat5.5，我自己用tomcat6,结果部署后，访问https://localhost:8443/cas 报错 错误如下：

　　使用将 WEB-INF\view\jsp\default\ui\casLoginView.jsp中

<!--也许是tomcat版本问题导致,替换为下面的代码<c:set var="query" value="<%=request.getQueryString() == null ? "" : request.getQueryString().replaceAll("&locale=([A-Za-z][A-Za-z]_)?[A-Za-z][A-Za-z]|^locale=([A-Za-z][A-Za-z]_)?[A-Za-z][A-Za-z]", "")%>" />
<c:set var="query" value="<%=request.getQueryString() == null ? \"\" : request.getQueryString().replaceAll(\"&locale=([A-Za-z][A-Za-z]_)?[A-Za-z][A-Za-z]|^locale=([A-Za-z][A-Za-z]_)?[A-Za-z][A-Za-z]\", \"\")%>" />-->
<c:set var="query" value="<%=request.getQueryString() == null ? "" : request.getQueryString().replaceAll("&locale=([A-Za-z][A-Za-z]_)?[A-Za-z][A-Za-z]|^locale=([A-Za-z][A-Za-z]_)?[A-Za-z][A-Za-z]", "")%>" />
　　修改了也没用，后来找到老外的解决方法
　　在catalina.bat中，在里面（前面）加上设置参数：

export JAVA_OPTS="-Dorg.apache.jasper.compiler.Parser.STRICT_QUOTE_ESCAPING=false"
　　结果小猫都启不动了
　　我自己修改为:

set JAVA_OPTS="-Dorg.apache.jasper.compiler.Parser.STRICT_QUOTE_ESCAPING=false"
　　启动小猫，访问https://localhost:8443/cas
　　终于看到登录的界面了。
　　被修改的那个参数具体描述请看：http://tomcat.apache.org/tomcat-5.5-doc/config/systemprops.html
