neccessary stepts to use Struts 2+FreeMarker+Tiles2.1
hi,
i'm in the precess of including Tiles 2 to my
Struts2+FreeMarker(+ServletAPI2.5)-project.
Things i did:
-add libs:
struts2-tiles-plugin-xxx.jar,
tiles-core-xxx.jar,
tiles-api-xxx.jar,
tiles-servlet-xxx.jar,
tiles-jsp-xxx.jar,
commons-beanutils-xxx.jar,
commons-digester-xxx.jar,
commons-logging-api-xxx.jar
spring-xxx.jar
-add listener in web.xml:
<listener>
<listener-class>org.apache.struts2.tiles.StrutsTilesListener</listener-class>
</listener>
-added the tiles-Result to my my-struts-default.xml (i know, i could habe
just extended tiles-default but i want to make tiles default="true" anyway).
-added an WEB-INF/tiles-defs.xml:
<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE tiles-definitions PUBLIC
"-//Apache Software Foundation//DTD Tiles Configuration 2.1//EN"
"http://tiles.apache.org/dtds/tiles-config_2_1.dtd">
<tiles-definitions>
<definition name="*" template="/layout/simpleLayout.ftl">
<put-attribute name="body" value="{1}" />
</definition>
</tiles-definitions>
-/layout/simpleLayout.ftl doesn't do anything usefull but i should provide
the HTML-Page with an <!-- test -->-String. It looks like this:
<!-- test -->
<@tiles.insertAttribute name="body" />
This results in the following error message:
...
INFO: Initializing Tiles2 container. . .
28.10.2008 15:59:13 org.apache.tiles.context.ChainedTilesContextFactory init
WARNUNG: Cannot find TilesContextFactory class

Apart from this error there are other things i'm not sure about:
-does Struts/Tiles find WEB-INF/tiles-defs.xml or do i have to set the
BasicTilesContainer.DEFINITIONS_CONFIG parameter?
-in simpleLayout.ftl do i have to include the tiles-jsp-lib myself (<#assign
tiles=JspTaglibs["???"]>
) or does the tiles-plugin do that? If i have to do it myself what is the
(local) address?

This is what I meant when I told you that I don't like how Struts 2
uses FreeMarker: it overrides the simple FreemarkerServlet with its
own plugins and custom servlet. It seems a bit baroque to me :-D
Anyway good luck

tiles-jsp-2.0.6.jar is located in /WEB-INF/lib. I think the freemarker error
with JspTaglibs was solved by adding the JspSupportServlet mentioned in the
struts2-documentation.
I uploaded the
http://www.file-upload.net/download-1215732/filestoreLevel2.war.html
war-file so you can take a look with
http://localhost:8080/filestoreLevel2/public/index.action

> I need to elaborate a bit...
Way to much work for me. The problem is that i don't need Tiles myself but
i'm compiling information for a struts2+freemarker+spring+hibernate-course
i'm giving. If tiles2.1 support for freemarker is not working the students
will have to work with tiles2.0 (albeit not having wildcards hurts quite a
bit. you really need one definition for every body content, don't you?).
So now i replaced the tiles2.1-libs with the tiles.2.0.6-libs, TilesListener
with StrutsTilesListener and my wildcard definition with a non-wildcard
definition. Unfortunately now i got a FreeMarker template error:
Expression JspTaglibs is undefined on line 1, column 16 in
layout/simpleLayout.ftl.
The problematic instruction:
----------
==> assignment: tiles=JspTaglibs["http://tiles.apache.org/tags-tiles"] [on
line 1, column 1 in layout/simpleLayout.ftl]
----------
Java backtrace for programmers:
----------
freemarker.core.InvalidReferenceException: Expression JspTaglibs is
undefined on line 1, column 16 in layout/simpleLayout.ftl.

<#assign tiles=JspTaglibs["http://tiles.apache.org/tags-tiles"]> doesn't
seem to be loaded, so after reading

add

<servlet-name>JspSupportServlet</servlet-name>
<servlet-class>org.apache.struts2.views.JspSupportServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
to the web.xml. But now i get an StackOverflowError:

I need to elaborate a bit. The current Struts 2/Tiles 2 integration is
a bit "patched", since it supports only partially the results of
Struts 2 and does not call the necessary code of
TilesContainerFactory.
I would create a StrutsTilesContainerFactory for Tiles 2.1, leaving
the one for 2.0 for compatibility reasons. Probably the new concept of
"Attribute renderer" could help a bit:
http://tiles.apache.org/framework/tutorial/advanced/attribute-rendering.html
The big problem is that Struts 2 manages FreeMarker without the
FreeMarker servlet. This poses a big problem if someone wants to use
FreeMarker for other purposes.
But there's another choice: use Tiles "without" Struts support. Struts
tags will be loaded anyway if you force the servlet to process the
"include" of resources. See
https://issues.apache.org/struts/browse/TILES-228?focusedCommentId=42840#action_42840
Anyway, for further questions about the Struts2/Tiles2 plugin ask the
Struts mailing list because it is developed there.

You might modify that code of StrutsTilesListener and, if you like,
post a patch to the Struts group. I think they might like it :-D (I

Re: neccessary stepts to use Struts 2+FreeMarker+Tiles2.1
Posted by Stephan Schröder <si...@gmx.de>.
I found a workaround for the wildcard definition problem:
Instead of
<definition name="*" template="/layout/simpleLayout.ftl">
<put-attribute name="body" value="{1}" />
</definition>
i use
<definition name="/*/*" template="/layout/simpleLayout.ftl">
<put-attribute name="body" value="/{1}/{2}" />
</definition>
Now the definition is found, but the simpleLayout.ftl isn't parsed by
FreeMarker it's simply returned as it is:
<#assign tiles=JspTaglibs["http://tiles.apache.org/tags-tiles"]>
<html>
<head>
<title>Test</title>
</head>
<body>
<@tiles.insertAttribute name="body" />
</body>
</html>
Is this caused by the listener class
org.apache.tiles.web.startup.TilesListener?
The http://struts.apache.org/2.1.2/docs/tiles-plugin.html
struts-tiles-plugin page notes org.apache.struts2.tiles.StrutsTilesListener
"provides tighter integration with Struts features such as freemarker
integration".
Now that the StrutsTilesListener is incompatible with Tile2.1 what can i do?

I resolved the issue with a "won't fix" since you can use the "**" to
match everything. The "/" is used as a separator.
Sorry, but i really forgot it :-(

No, it works as long as you put tiles-jsp-xxx.jar under WEB-INF/lib,
or if you define it in web.xml.

Mmm... This problem is not due to the presence or not of that file,
but it seems that Tiles cannot find the *definition* called
"/public/files_show.ftl". This is strange since you put the "*"
wildcard.
Probably it is a Tiles bug. Can you open a JIRA issue and, if
possible, attach a test case (i.e. a WAR file with sources).

You have to. Eventually you can use the "tiles.xml" name to your file
if you don't want to use this parameter. Notice that this
configuration parameter has been deprecated. Use this instead:

You have to include it yourself, put the URI of the taglib:
