RE: XML include hack to split struts-config.xml
I've never gotten it to work either, but I would love to hear a solution myself. I know what is suppossed to happen, but I haven't seen anyone concretely give their example of doing it. dan -Original Message- From: Renaud Waldura [mailto:[EMAIL PROTECTED]] Sent: Monday, September 10, 2001 4:08 PM To: [EMAIL PROTECTED] Subject: XML include hack to split struts-config.xml I found out about the XML include hack that can be used to split the struts-config.xml in more manageable portions: http://jakarta.apache.org:8080/jyve-faq/Turbine/screen/DisplayQues tionAnswer /action/SetAll/project_id/2/faq_id/16/topic_id/196/question_id/752 It's been mentioned many times before on this list, but I'm having a hell of a time getting to work, especially with relative paths. Is anyone doing this in the context of WAR deployment? My current declaration is like this: !DOCTYPE struts-config PUBLIC -//Apache Software Foundation//DTD Struts Configuration 1.0//EN http://jakarta.apache.org/struts/dtds/struts-config_1_0.dtd; [ !ENTITY downloadClientActions SYSTEM file:./WEB-INF/config/struts/actions-downloadClient.xml ] But it chokes with a I/O error. Using an absolute path in the file: URI makes it work, but this is highly undesirable. I've tried every combination I could think of, no luck. Struts-config is fed to the ActionServlet with: init-param param-nameconfig/param-name param-value/WEB-INF/config/struts/struts-config.xml/param-value /init-param Any clues? --Renaud
anyway to flush the MessageResources?
Hi,
Is there any way to flush the message resources cache?
My requirement is to be able to dynamically edit labels
without bouncing the servlet container. I have my own
MessageResources implementation that connects to our
own dictionary which is loaded from the db. So the
problem is that even though I have changed a value associated
with a key and it is persisted to the db, the new call
never gets made due to the caching in the method below. I am using
the struts 1.0 release.
Right now I am thinking the only solution is to subclass ActionServlet,
and then provide a public wrapper for the initApplication() method, so
that I can call it from an action class, but I just want to make sure there
isn't an easier way, as I have been avoiding subclassing the ActionServlet
for a few months now ;)
thanks,
dan

splitting of struts config was RE: ActionServlet.addMapping() persistence
Craig, or anyone, Has anyone actually gotten the below xml inclusion mechanism to work using struts and tomcat 3.2.1? I searched other messages about this in the archives and none of the authors were successful. I always get a parse error like: che/struts/resources/web-app_2_3.dtd' Parse Fatal Error at line 5 column -1: Relative URI forms.xml; can not be reso lved without a document URI. org.xml.sax.SAXParseException: Relative URI forms.xml; can not be resolved wit hout a document URI. Our application is getting large and I would dearly like to use this idea to split up the config file thanks, dan -Original Message- From: Craig R. McClanahan [mailto:[EMAIL PROTECTED]] Sent: Wednesday, August 08, 2001 12:41 PM To: [EMAIL PROTECTED] Subject: Re: ActionServlet.addMapping() persistence There's an XML trick that lets you do this without needing to modify Struts. Consider that you've got a struts-config.xml file divided into three parts (form-beans.xml, global-forwards.xml, and action-mappings.xml) stored in the /WEB-INF directory. They can be combined automatically by doing something like this in struts-config.xml: ?xml version=1.0? !DOCTYPE ... [ !ENTITY part1 SYSTEM form-beans.xml !ENTITY part2 SYSTEM global-forwards.xml !ENTITY part3 SYSTEM action-mappings.xml ] struts-config form-beans part1; /form-beans global-forwards part2; /global-forwards action-mappings part3; /action-mappings /struts-config Obviously, you can extend this concept to any reasonable separation of struts-config.xml into subordinate files. I suppose I could update struts-config.xml and then tell the ActionServlet to reread it in the Action I talked about in the first paragraph...I'd like to be able to seperate this out, if possible, to make the seperate components of my webapplication seperate. The problem with putting this all into individual webapps is that I want the session to be passed from one part of the webapp to the next. The other approach would be to keep the individual pieces of struts-config.xml in separate files in your source repository, and use the Unix cat tool (or the DOS copy tool using plus signs) to concatenate the pieces together as you deploy the web app. Any thoughts? Thanks, Becky Craig
localization of numbers, etc.
I am wondering if the struts html:text tag supports the localization of number formats? And if not, whether it even should? thanks, dan
how to restrict direct access to jsps(and have struts work)
Hello, I'm using Struts and Tomcat 3.2.1. Is it possible to set things up so that jsps cannot be directly accessed at all, but must always be referenced through an action? I had writen a checkLogon tag for inclusion in each jsp when the above question occured to me. I've looked at web.xml descriptions etc., but I don't really want to setup role based security, I just want any URL of the type http://localhost:8080/CompEnterprise/jsp/ to get a 404, yet still allow Struts to forward to them and work...this would allow me to do logon validation within the actions and not the jsps. This would also solve the problem of someone going to a jsp that depends on request data that is set by the action. thanks, dan
can someone post an example of bean:message using parametric replacement
Hi, Can someone post a concrete example of a bean:message ... tag using parametric replacements and also post the corresponding lines from the properties file. I am having some difficulty understanding it. thanks, dan
RE: can someone post an example of bean:message using parametric replacement
thanks. I'm trying to figure out how to setup correctly for
localizition, especially where you have cases like
Product Name
versus (excuse my spanish)
Nombre de Producto
thanks again,

ok, let me try again.
in ApplicationResources.properties:
error.field.required=Field {0} is required.
in Action class; perform() method:
ActionErrors errors = new ActionErrors();
...
try {
[parse field]
[if field is required, but is not found] throw new
ParseException("[field
name]");
} catch(ParseException pe) {
errors.add("field", new ActionError("error.field.required",
pe.getMessage());
saveErrors(request, errors);
return mapping.findForward("failure");
}
The {0} will be replaced by the value returned by 'e.getMessage()', so if
[field name] is Address, the error message should read 'Field Address is
required'.
Hope this helps (more than my last response),

how to access related ActionForm from within .jsp?
I am having a common problem all over the place.
Struts allows you to associate a bean(the ActionForm)
with a given .jsp. It then magically gets and sets
input fields for you. Great.
But all of the other struts tags require a reference
to a bean by name, using the name="foo" argument
to the tag.
My problem is, I want to reference the bean associated
with my jsp, so that when I want to iterated over a collection
it contains, I can do so without having to know the bean's name.
example:
public final class FooForm extends ActionForm
{
public Collection bar;
public Collection getBar()
{
return bar;
}
public void setBar(Collection b
{
this.bar = b;
}
}
then in my jsp:
logic:iterate name="???" id="criterion"
TR
TDbean:write name="criterion" property="propertyName"//TD
TDbean:write name="criterion" property="operator"//TD
TDbean:write name="criterion" property="propertyValue"//TD
/TR
/logic:iterate
So the iterate tag doesn't work because it wants a bean by name, but is
there something I haven't gotten that will make struts use the bean
associated with the jsp and not one specified by name?
thanks,
dan
RE: how to access related ActionForm from within .jsp?
Thanks for your advice. I really just wanted
to prevent having to duplicate hard coded form bean
names, i.e. in my jsps and in the config.xml.
I wrote a tag to get it from the action mapping,
but alas, that didn't work either. For one, my
action mapping was null(probably some misconfig on
my part). Secondly, it looks like when you
nest a custom tag within the attribute of another
custom tag, it doesn't get evaluated, so
doing logic: iterate name="mylib:getFormBeanName /" ... /
won't work anyway. Although this works fine for html tags.
thanks,
dan

The form bean is associated with an action, not a jsp. The jsp may contain
an html:form which references an action, thereby gaining access
to the form
associated with that action. A jsp could have multiple html:forms.
The form bean associated with the action is available in request scope for
the jsp but I don't know how you would get access to it without using the
name of the form. Is there a struts tag that will get actionmapping values
when given the name of the action? That would allow you to get
the form bean
name using the same action used by the html:form.
Maybe you could use the bean:struts tag to get the action mapping and then
get the form from that.
