Is it possible to get Struts' FilterDispatcher to serve up static files

[mraible]

I'm using *.html as my default extension, which causes a whole host of issues with Dojo.  Regardless, I want to fight through it and see if I can come up with a solution.

I noticed that FilterDispatcher allows you to serve up static files from the classpath.  Is it possible to configure this same filter so it can serve up static .html files from a "static" directory in my webapp root?

Thanks,

Matt

Quoting the doc: "

Common static content that is needed by the framework (JavaScript and CSS
files, etc.) is served automatically by the FilterDispatcher filter. Any
request starting with "/struts/" denotes that static content is required,
and then mapping the value after "/struts/" to common packages in Struts 2
and, optionally in the application's class path.

By default, the following packages are searched:

   - org.apache.struts2.static
   - template

Additional packages can be specified by providing a comma separated list to
the configuration parameter named "packages" (configured in web.xml for the
FilterDispatcher filter). When specifying additional static content, you
should be careful not to expose sensitive configuration information (i.e.
database password)."

Is there a FAQ for S2 somewhere?

Right, it can serve up static content from the classpath, but I want to do it from the webapp.

Hi Matt,

I'm not sure about your specific FilterDispatcher question, but we also use
*.html as a default extension. We ended up copying all the dojo html files that
we use into out own /WEB-INF/widgets directory and adding an extra
struts-dojo.xml file to our config:

<!DOCTYPE struts PUBLIC
        "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
        "http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>
    <package name="dojo" namespace="/struts/dojo/src/widget/templates"
extends="base">
        <action name="*">
            <result type="plainhtml">/WEB-INF/widgets/{1}.html</result>
        </action>
    </package>
    <package name="dojoEditor2"
namespace="/struts/dojo/src/widget/templates/Editor2" extends="base">
        <action name="*">
            <result type="plainhtml">/WEB-INF/widgets/Editor2/{1}.html</result>
        </action>
    </package>
    <package name="dojoEditor2Dialog"
namespace="/struts/dojo/src/widget/templates/Editor2/Dialog" extends="base">
        <action name="*">
            <result
type="plainhtml">/WEB-INF/widgets/Editor2/Dialog/{1}.html</result>
        </action>
    </package>
</struts>

It seems convoluted, but it's working. The other dojo files (css, js, etc) are
working fine from within the struts jar.

I came up with a StaticFilter (from http://issues.appfuse.org/browse/APF-431) that seems to work (see code below).  However, it causes another issue for me. In my SiteMesh decorator, I'm including a messages.jsp that has calls to the valueStack:

<%-- ActionError Messages - usually set in Actions --%>
<s:if test="hasActionErrors()">
    <div class="error" id="errorMessages">    
      <s:iterator value="actionErrors">
        "
            alt="<fmt:message key="icon.warning"/>" class="icon" />
        <s:property escape="false"/><br />
      </s:iterator>
   </div>
</s:if>

<%-- FieldError Messages - usually set by validation rules --%>
<s:if test="hasFieldErrors()">
    <div class="error" id="errorMessages">    
      <s:iterator value="fieldErrors">
          <s:iterator value="value">
            "
                alt="<fmt:message key="icon.warning"/>" class="icon" />
             <s:property escape="false"/><br />
          </s:iterator>
      </s:iterator>
   </div>
</s:if>

When I return a static page, this JSP causes issue:

java.lang.NullPointerException
        at org.apache.struts2.views.jsp.TagUtils.getStack(TagUtils.java:58)

This works fine when I request a Struts Action.  Is there any way to check for the stack in my messages.jsp?

Thanks,

Matt

I think that the struts2 FAQ is here http://struts.apache.org/2.0.6/docs/faqs.html 

I couldn't find anything relevant (after 3 mins). But in http://struts.apache.org/2.x/docs/strutsproperties.html i saw this:

### Used by FilterDispatcher
### If true then Struts serves static content from inside its jar.
### If false then the static content must be available at <context_path>/struts
struts.serve.static=true

which might help?

I don't think so, if you set it to false, I think you will have to unzip all
the dojo, and templates stuff into that folder, which is not desirable
(unless you want to use your own version of Dojo)

[Felipe Rodrigues]

Take the static content out of .jar, doesn't help the performance?
I know that taking the template directory out of jar helps a lot at performance when rendering ui.
Doesn't it heppen the same with static content?

best,

Felipe
