Is your JS code meant to be executed, or just displayed as it is?

If you have the former situation, is your code inside <script type="text/javascript">...</script> tags?

If you have the latter situation, then characters such as < HAVE to be converted to &lt, otherwise they would be read as HTML tags by your browser.

JSP does by default not do that. Aren't you actually using JSTL <c:out> to print JavaScript code? It can namely do that. You could disable that by adding escapeXml="false" attribute.

Anyway, best would always be to put JS code in its own .js file which you then include in the head as follows:

<script src="script.js"></script>

Hope this helps....

function toHtml(myString)
{
    htmlString = myString.split("&lt;").join("<");
    htmlString = htmlString.split("&gt;").join(">");
    htmlString = htmlString.split("&quot;").join("\"");
    htmlString = htmlString.split("&apos;").join("\'");
    return htmlString;
}
