JSP scripting question

Scruff

On a JSP page i have i display the results of and sql query from a MySql db. The problem is that one of the table rows contains a string that may contain regex elements, that are use by a non application for string matching.

the problem is that i dont want to display these regex elements on the web page.

For example, the regex string stored in the db could be "test\s+string"
The string i want to display on the web page is "test string"
So in essence what i i'm trying to do is replace "\s+" with " ".

I know how to do this fine in ASP using vbscript and jscript but i'm confused as to how to achieve the same effect in a JSP page.

heres an example of the code i'm using at the moment to display the results (with the code in red i need to change):

<sql:query var="regexString">
SELECT id, matchstring FROM myDB
</sql:query>

<table border="0" align="center" cellpadding="0" cellspacing="0">
<tr>
  <td>ID</td>
  <td>String</td>
<tr>

<c:forEach var="row" items="${regexString.rows}"
<tr>
  <td width="129" align="center" >
    <c:out value="${row.ID}"/>
  </td>
  <td width="129" align="center" >
    [COLOR=red] <c:out value="${row.matchstring }"/>[/COLOR] 
  </td>
</tr>
</c:forEach>

any ideas

You can get matchstring into a Java String by doing the following:

<c:set var="matchString" value="${row.matchstring}" scope="page"/>

<%
String matchStr = (String)pageContext.getAttribute("matchString");

// manipulate matchStr the same way you do it in jscript

pageContext.setAttribute("fixedMatchStr", matchStr);
%>

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

Ideally you would write your own tag to do this so as to take all that ugly scriptlet code out of the page. Fortunately writing your own tags these days is really easy.

Hope this helps
