Yes, freemarker is used by Struts 2 tags to generate html. We could
have a
property for the cache setting, but, does it solve your problem?
(you said
it was partially resolved)
Most of the garbage is still there but at least about 400-500 MB
generated from freemarker classes seems not there anymore.
I tried to use jrockit instead of sun jvm since it has a better
memory analyzer but I haven't been able to produce a report yet.
May I ask more on how struts2 is using freemarker ?
How is freemarker used in a code snippet like this :
<td width="34%" valign="bottom" class="fontNormale"
align="center">
<span>
<s:form name="RicercaArticoliVisOrdina"
action="RicercaArticoliVis">
Ordina per <s:select list="%
{listaOrdinamentoArticoli}" value="${numeri.ordinamento[0]}"
name="ordinamento" onchange="document.RicercaArticoliVisOrdina.submit
()"/>
<s:hidden name="idRicerca" value="$
{numeri.idRicerca}"/>
</s:form>
</span>
</td>
<td width="33%" valign="bottom" class="fontNormale"
align="right">
<span>
<s:form name="RicercaArticoliVisDimPagina"
action="RicercaArticoliVis">
Mostra <s:select list="{5, 10, 20, 30}"
value="${numeri.dimPagina}" name="dimPagina"
onchange="document.RicercaArticoliVisDimPagina.submit()"/> prodotti
per pagina
<s:hidden name="idRicerca" value="$
{numeri.idRicerca}"/>
</s:form>
</span>
</td>
What object are created ?
Thanks

I discussed the problem with the freemarker team and I used a
suggestion that PARTIALLY resolved.
They said :
=====
You can use the code below to enable the model cache, assuming
"myConfiguration" is the reference to your Configuration object:
((BeansWrapper)myConfiguration.getObjectWrapper()).setUseCache(true)
and see if it helps you with your GC load levels.
=====
This actually seems to happen.
In struts how can this be done ? I used :
freemarker.template.Configuration fmc =
(freemarker.template.Configuration)
ServletActionContext.getServletContext().getAttribute
(FreemarkerManager.CONFIG_SERVLET_CONTEXT_KEY);
if (fmc != null) {
((freemarker.ext.beans.BeansWrapper)fmc.getObjectWrapper
()).setUseCache(true);
}
but I think there must be a configuration somewhere
(struts.properties?).
To completely solve my problem I really need to understand the
following :
How struts uses freemarker ? If i have a jsp page that contains html,
jsp tags, struts tags and jsp EL expression, where freemarker is
used ?
I suppose that it's used ONLY on struts tags...
So if my page is composed primarly of jsp EL and jsp tags and a few
struts tags can I focus on struts tags only to try to understand why
the app is producing garbage ?
Thank you
