In your jsp code set a variable to be the value you want, as shown
earlier in this thread by Balwinder, and then read that variable in
your Javascript code. If you're using OO javascript, you can make it
nice and tidy by passing the parameter in your "constructor", or set
it in a method. Example:

var obj = new FancyObject('<bean:message key="app.mykey" bundle="MESSAGE">');
// -- or --
obj.setSomeValue('<bean:message key="app.mykey" bundle="MESSAGE">');

Make sense?

Not really: you're trying to access server-side resources from the client side. If you're not going to run your JavaScript through the JSP processor your options are limited, for obvious reasons.

One solution was already given to you: deal with server-side resources in the JSP, use them as arguments to JavaScript functions contained in an external JavaScript file, by using custom tags, scriptlets, etc. to set parameter values.

You can also generate JavaScript on the server-side by means other than a JSP (FreeMarker, servlet, etc.), or generate JavaScript during the build process, or generate the JavaScript at application startup, or use something like DWR to access a Java object that loads resources at runtime, or... ad nauseum.

The underlying issue won't go away; there's client-side resources, and there's server-side resources. That's one of the many unfortunate natures of web applications, AFAICT.

That's most likely not what you wanted, you mean:

<% String aString = "Hi There!"; %>

Hopefully that was typos.

Do you have scriptlets enabled?

Er, if *that* doesn't work, then you've done something horribly wrong, because that's just calling a JavaScript function with a literal string.

Periodically, I run into this problem and find out that I don't have
*.js files mapped to the JSP servlet in Tomcat. It may not be your
problem, but if you are running javascript that comes from a separate
file with a .js file extension, tags and scriptlets don't work unless
you have mapped them to the JSP servlet.

I've had this problem when using tags in both JS and CSS files. It's
easy enough to fix, but it's a mistake I make with every project I start
from scratch and always takes me an hour or more to figure out :)

-Wes

PS - Dave, I caught myself this time, I almost sent this only to you
again!

I had the same problem, and someone pointed out to me that it does say in
the s:include reference page
(http://struts.apache.org/2.x/docs/include.html) that parameters passedvia
s:include are not available on the stack. Well...it doesn't phrase it that
way, but that's basically it.

Yes, it's silly......but what to do about it?

I kludged it by using JSTL to insert that parameter into the page context.
Put this in your included page:

<c:set var="myParam" value="${param.myParam}"/>

Then #attr.myParam will work.

I¹m really starting to develop a love-hate (and fear) relationship with
OGNL. Please bear with my long winded explanation, it' therapeutic (for me
at least). And, please, I really do need help.

I'm finding using OGNL like dating a supermodel, who also suffers from
multiple personality disorder and Turrets. At first it's hello OGNL, your
having breakfast at some uptown café, expensive glossy mags littered around
the place, ordering eggs on some exotic bread and coffee that monkeys
excrete. You know the feeling. You're interacting with stack, calling
methods, the odd lambda expression. Your on top of the world. It's a case
of
JSP - who, expression language - what?

Next thing you know, BAM!! You're wearing your breakfast, feeling the pain
of 300 pages of last month's Italian Vogue across the back of your head and
longing for the security of a bagel and filtered coffee with JSP.


Take my current problem. A simple task of passing a parameter to an
included
page.

<s:include value="myPage.jsp>
  <s:param name="myParam">2</s:param>
</s:include>

And in myPage.jsp I have

<s:property value="#parameters.myParam/>

BAM!! There's that Italian Vogue again.

So I try:

<s:property value="#parameters['myParam']/>

and

<s:property value="%{#parameters.myParam}/>

and

<s:property value="myParam/>

and

<s:property value=%{myParam}/>

Now I'm reaching for the Ibuprofen. You also see where the Turrets comes
in.

If I now look at my once loved, then hated, now missed JSP:

<c:import url="myPage.jsp">
  <c:param name=myParam">2</c:param>
</c:import>

And in myPage.jsp I have ${params.myParam}. Bingo! Bagel and coffee.

Please somebody please point out my error as I know it must be MY ERROR,
but
I just can't see it.

I've read the stuff on the struts wiki which indicates that my example
should be working. The OGNL site is too generic to be of much use here.

As an aside, if any budding author wants to produce an InfoQ style guide to
OGNL and struts I'd happily spring for it.

I'm not asking a lot. We all have flaws. I'd just like to settle into a
little monogamy for a while - until the next supermodel at least.

Z.

You *can* retrieve them, just not in the way you want. They're added as request parameters and available via JSP EL like so:

${param.foo}

I'm a bit fuzzy on the details but I don't believe the action tag goes through the normal request process but instead invokes the action through a proxy--that may short-circuit the interceptor stack and so on, but I'd rather someone with a bit more knowledge tackled that question.

Personally I think the action tag has more serious issues than this relatively minor one.

Not all that early, really.

Since you follow struts-dev you know that issues like this are discussed frequently. Also bear in mind that *your* useless may not be somebody else's. And, as with all volunteer efforts, the things that matter most to the committers are the ones that tend to get dealt with first, and that time is often quite limited.

If you have a particular itch to scratch patches are always welcome--feel free to contribute a fix (or more) to the action tag so it exhibits the behavior you want (or a completely new tag); it'll most likely be reviewed and evaluated.

I'm trying to set a whole hierarchy (from a TON of checkboxes) coming in to a
request and not having much luck. I'm using the spring object factory.

I don't know whether the problem is in xwork, Spring, Struts or me. Is what
I'm trying even possible?

Thanks!
--Jeff




------------EXAMPLE-------------------

Here's a simple case of what I'd like to do:

http://localhost:8080/picsWeb2/Test.action?data[12][5][hi]=true

Here's the error I'm getting: ERROR - ParametersInterceptor -

 public String execute()
 {

 }

 public Map<Integer, Map<Integer, Map<String, Boolean>>> getData() {

 }

 public void setData(Map<Integer, Map<Integer, Map<String, Boolean>>> data)

 }
}

Well at first glance, I'm pretty sure that "[hi]" isn't going to work, since the "hi" isn't enclosed in quotes, so will make a crappy string.

I've used a slightly different, but similar, hierarchy without issues.

Not sure what Spring has to do with anything here.

Thanks Dave. It actually looks like adding the ticks doesn't work (though
I'll confirm that IS a reason why it wouldn't work).

It's good to know someone's gotten something similar working, though... I'll
keep tinkering with it.

Is there any word on getting a more verbose error message than this?

Assuming Struts2, the s:action tag can only execute an action and
execute where that result can be included within the current
outputstream (eg. including a JSP fragment).

I redirect result makes no sense in this context as the output stream is
already open and written to.

I can confirm that a Tiles result (Struts2 result of type tiles) does
not work in this context either as it throws an exception that the
outputstream has already been opened (or something like that; I can't
recall exactly but it's in JIRA somewhere under the Tiles2 plugin).

In cases where I've needed this behaviour I've referenced the JSP
instead of a Tile.

Hope that helps,

I find it unlikely that the <s:text.../> tag is adding an element to your body element. AFAIK the text tag has no ability to do this. I'd suggest posting more information about the source JSP, your configuration, etc.

Thanks Dave, that works!

I finally also found a working example here:
http://javachamp.blogspot.com/2008/06/struts-2-ajax-drop-down-example.html

You can actually get rid of any javascript functions and just publish the
topic in the onchange and use die struts div tag to do the rest:


<s:form id="regionClassForm" theme="ajax" action="occResourceStatsByRegion"
namespace="/ajax">
 <s:hidden name="resource_id" value="%{resource_id}" />
 <s:select name="region" list="regionClasses" value="region"
onchange="dojo.event.topic.publish('imgByRegion_topic');return false;"
theme="ajax"/>
</s:form>
<s:url id="imgByRegionUrl" action="occResourceStatsByRegion"
namespace="/ajax" includeParams="none"/>
<s:div id="imgByRegion" href="%{imgByRegionUrl}" formId="regionClassForm"
listenTopics="imgByRegion_topic" theme="ajax"></s:div>


pretty nice.

<action name="*">
 <param name="something">something</param>
</action>

What is the use of param here? I thought it would call
setSomething("something") on my action, but it won't.

It means you have a bidirectional association between two of your
entities (common).

Change the CycleDetectionStrategy discussed at jsonlib

http://json-lib.sourceforge.net/usage.html

In struts2, substitute the default JSON ContentTypeHandler with one that
uses jsonlib with your customized settings.

Hope that helps.
