[FreeMarker-user] templating with no file based system (OSGI question)

FreeMarker template loading is not file system based. See
Configuration.setTemplateLoader(...), or the convenience methods like
setClassLoaderForTemplateLoading. So as far as OSGi allows the
FreeMarker classes to access the classes of the other bundle (which
contains the templates), a ClassTemplateLoader should do the trick.

Hi All,
I am developing a web application based on OSGI. I have templates
on different bundles and want to produce a html code by merging
differnt ftl files which are on different bundles. I need this
scenario because I need versioned templates...
I am expecting to find JAVA API Documentation but could not find. I
want to implement programmatically which is done as below with Freemarker template language.
<#macro myLayout>
<html>
<body style="width:100%;height:100%">
<table border="1" cellspacing="0" cellpadding="0" style="width:100%;height:100%">
<tr>
<td colspan="2">
<#include "header.ftl"/>
</td>
</tr>
<tr>
<td>
<#include "menu.ftl"/>
</td>
<td>
<#nested/>
</td>
</tr>
<tr>
<td colspan="2">
<#include "footer.ftl"/>
</td>
</tr>
</table>
</body>
</html>
</#macro>
I need such hypothetical java api which does above templating.
Freemarker.macro("mylayout.ftl")
.include(1,"header.ftl")
.include(2,"menu.ftl")
.include(3,"footer.ftl")
.process(FileUtils.read("nested.ftl"));
I see that Freemarker include directive refers to the files, meanly
it is file system based. I could not find a documentation which
helps me do it programmatically as above...
I am on a wrong way? or I missed something in the understanding of
Freemarker architecture? I don't know...
Could you please help me on this issue?
thanks in advance,
-halil.
