JSTL Scriptlet到Java类

Question

I'm pretty new to Java so bear with me. I have a scriptlet that is put into a JSTL tag. I'm trying to do away with my scriptlets and put them in a seperate class. Except I'm really stumped on this one. I have a pretty basic Java method:

static final String default = "Enter a message";

String subDate(String out){
    final String year = "" + Calendar.getInstance().get(Calendar.YEAR);
    return out.replaceAll("%CURRYEAR%", year);
}

In my JSTL I call it like below

<c:out value="<%= subDate(msg) %>" default="<%= subDate(default) %>"

When I'm converting this to my Java class this is what I have. But I'm simply not getting anything. I'm also really confused on how I would pass it multiple parameters like I'm doing in my JSTL.

public String getsubDate(String in){        
    return in.replaceAll("%CURRYEAR%", YEAR) + getMsg();            
}

Any help is greatly appreciated!

Since it sounds like you're putting msg on the request in the servlet using request.setAttribute , you can get the correct year in the servlet, replace all occurances of %CURRYEAR% right there and just put the correct message on the request:

String year = "" + Calendar.getInstance().get(Calendar.YEAR);
request.setAttribute("msg", msg.replaceAll("%CURRYEAR%", year));

Then on your page just do this:

<c:out value="${msg}" />
