请问在jsp中怎么样用replace把\n替换成 <br>

我用的是jdk1.5版本 
我用这种方法替换cont=cont.replaceAll("\n","<br>"); 
但是在运行的时候提示错误为：
org.apache.jasper.JasperException: Unable to compile class for JSP

An error occurred at line: 5 in the jsp file: /Post.jsp
Generated servlet error:
String literal is not properly closed by a double-quote

再加个/呢

还不好使。。。

JScript code

cont=cont.replace(/\n/g,"<br>")
