FreeMarker

I want my own template loader for FreemarkerServlet. So I need to override
"factory creation" method. I've attached a diff for this.

How to use it:
1) extend FreemarkerServlet:
-----------------------------------------------
public class CMSFreemarkerServlet extends FreemarkerServlet {

protected void processTemplatePath(String templatePath) throws
IOException {
if (templatePath.startsWith("custom")) {
Configuration cfg = getConfiguration();
cfg.setTemplateLoader(new CMSSnippetLoader());
}
else {
super.processTemplatePath(templatePath);
}
}



class CMSSnippetLoader implements TemplateLoader {


public Object findTemplateSource(String name) throws IOException {
// HERE YOU CAN LOAD YOUR TEMPLATE
String snippetName = name.replace(".snippet", "");
return findSnippetByName(snippetName);
}

public long getLastModified(Object templateSource) {
return System.currentTimeMillis();
}

public Reader getReader(Object templateSource, String encoding)
throws IOException {
return new StringReader(((Snippet)templateSource).getValue());
}

public void closeTemplateSource(Object templateSource) throws
IOException {
}
}

}
---------------------------------------


2) in web.xml:
---------------------------------------
<servlet>
<servlet-name>freemarker</servlet-name>
<servlet-class>CMSFreemarkerServlet</servlet-class>

<!-- FreemarkerServlet settings: -->
<init-param>
<param-name>TemplatePath</param-name>
<param-value>custom</param-value>
</init-param>
<!-- other stuff -->
</servlet>

<servlet-mapping>
<servlet-name>freemarker</servlet-name>
<url-pattern>*.snippet</url-pattern>
</servlet-mapping>
-------------------------------------

3) Now you can include snippet:
-------------------------------------
RequestDispatcher disp =
request.getRequestDispatcher("coolsnippet.snippet");
disp.include(request, response);
-------------------------------------
