tomcat 6 部署 cas3.3.1 server 访问报错。
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

1 楼 littlecong 2009-09-21 两个修改看起来是一样的，可能只是unix和windows上的差别
