Hi,

Struts2 use XWork Validation Framework, so you can use it

hi,

i am having a problem with the name attribute of s:submit tag.  I may be
using it in the wrong context as i am farily new to Struts 2.  My problem is
that i want to set a property of a class with the value of the submit
button, which i assume would be "submit".  The problem is that the property
is not set and has a value of null when the submit button is pressed. My
code is below:

JSP Page:

<s:submit name="action" action="Submit" method="getReport" value="Submit"/>

Class:

private String action;

Can anyone assist me in my problem?


many thanks
mark

Hi,

> <s:submit name="action" action="Submit" method="getReport" value="Submit"/>

Just look for source of your page and you will see why. If you want to
use either method or action (not both), maybe it will be better to add
hidden field?

Hi,

I am currently working on a little application which needs a user interface for administration. I think an embedded app server with a Struts based application might be a good choice. But one big obstacle is in the way, I fear: the size of such a solution.
What do you think is the minimal solution giving the comfort of a Struts based approach and not dominating the workhorse app with tons of jars only needed for the small admin part?
Jetty as an App server? Or Tomcat? Or some other, really small? Struts 1 or 2 (I would think Struts1 is the smaller solution)? Or shouldn't I attempt this approach and write a simple servlet? What do you do?
I cannot assume a Servlet container to be installed on machines my app will run on. There might be multiple instances of my app running on the same machine. The UI should work over the network although a console based approach might be possible, too.

Thanks in advance

Martin

Attachment: user_187959.ezm (zipped)

I know of several projects using Jetty to embed and distribute their
web applications. Jetty is easy to configureand embed (with xml or
programatically). Take a look at
http://docs.codehaus.org/display/JETTY/Embedding+Jetty to get started.

This sounds a little suspicious! When you say " I cannot assume a Servlet
container to be installed on machines my app will run on" what do you mean?
I would hope you are planning to host this from a server someplace, right?
Not sure about your environment, but you could always use an ISP to host
your Struts application. I use DailyRazor and have full control over the
server and none of the headaches of babysitting the machinery.

Thanks Martin, I have found some tricks in mailerReader, but not what I'm
looking for.

Jeromy, thanks for your suggestion. May you help me once again and guide me
on the code? I've been trying to do what you said me, but I cann't get it
run.

Thanks again.

What specifically are you having issues with? If it's FreeMarker issues you might have better luck on a more appropriate FreeMarker list/forum. It's pretty straight-forward, though.

Attachment: user_187951.ezm (zipped)

Ok. The subject: render a JSP/Freemaker/Velocity file in a Struts Action, to
send an email. I mean, the "problem" is getting the HTML email body from an
Action. The action skeleton would be:

public void sendEmail extends ActionSupport {

private String username;

public String execute() {
// Validate parameters;
....
// Send email
Email mail = new Email();
email.setFrom("foo@(protected)");
email.setTo("*ben@(protected)*");
email.setSubject("welcome");
email.setBody(*this.renderJSP()*);
Mailer.send(email);

// Response to user.
return ActionSupport.SUCCESS;
}
}

The problem is "renderJSP" method, so it constructs a customized JSP with
username data. For example, "renderJSP" should return something like:

<html>
<body>
<p>Welcome *ben@(protected)>
<p>this is a welcome email.</p>
</body>
</html>

The object is render this email inside the user request. For me, it's not
important the template engine (JSP, FreeMaker, Velocity); the main thing is
getting it run from an Action.

Thanks again for your help and patience.

Do this:
http://freemarker.sourceforge.net/docs/pgui_quickstart_all.html
inside your action.

(where test.ftl contains the html above)

then pass the result to your emailer.

Hi all,
We're using struts 1.2.4 in our project and we just noticed something; 
When rendering a <html:hidden> element the html produced is:

<input name="id" value="1019" type="hidden">

Notice that it doesn't close the tag properly like /> as required by xhtml. Is there a way to 
tell struts to close properly for xhtml or we have to upgrade?

Thanks

Use <html:xhtml> before the first <html:*> tag of every JSP page.
BTW I suggest to upgrade to Struts 1.2.9 (at least) because
<html:form> in Struts 1.2.4 does not produce XHTML-strict compliant
code (in particular it creates the "name" attribute).

Thanks for the info for the form tag. The problem is we use tiles, so 
html:xhtml is not really an option.
A colleague will try to do a controller trick in web.xml, but from what 
I feel we'll have to upgrade.

Why? <html:xhtml /> does not produce any markup code, only tells
Struts tags to render in XHTML.

Ahh, ok, confused it with    <html:html xhtml="true">
which produces the <html> tag.

Anyway, I'm trying to upgrade to struts 1.3.8 but I get an exception
when trying to view the first page:

Fortunately didn't have a lot of trouble with ActionError as most 
dependencies were gone (remember my previous posts about correct use of 
ActionMessages?),
the projects builds and deploys fine. Any idea why we get these exceptions?

Mmm... Just a shot in the dark, did you put the commons-chain.jar in

Yep, right from the struts lib directory. One thing to note though is 
we're using xdoclet 1.2.3 to
create struts-config.xml for us. As I understand this version of xdoclet 
supports up to struts 1.2.x.
Could this be the culprit? That it doesn't produce a proper 
struts-config.xml? Because from what I
saw web.xml is very similar to 1.3.8's web.xml from the blank web app 
example.

Probably. According to the source file:
http://svn.apache.org/repos/asf/struts/struts1/tags/STRUTS_1_3_8/core/src/main/java/org/apache/struts/chain/commands/servlet/PerformForward.java
it seems that a request dispatcher is not found, that is *really*
strange, and, IMHO, can only happen when a webapp did not start
correctly. Do you see an error at startup?

No, everything seems to start smoothly. I'll try to create a 
struts-config.xml file by hand just for the home action  and see what 
happens.

I'm not sure it's the struts-config.xml file anymore. I'm using this:

which is from another 1.3.8 sample app and I just added the action

Could it be that it's not finding a proper jar or something?

Sorry, I don't understand your response. Was this about one of my questions

Make sure your validation xml is named as "ActionClass-alias-validation.xml", if you want to apply it only to one method in ur action class
Naming it as "Actionclass-validation.xml" would apply your validation to all methods in your action.

Hello,

We're moving from a Struts 1.x with Tiles development model to Struts 2
and Sitemesh.

One thing we miss with from Tiles is the ability to back a JSP with a
Controller. The Controller guaranteed that whenever a JSP was rendered,
certain behavior was executed to prepare data for the JSP. For example,
the loading of data for drop-down select boxes was often placed in the
Controller.

Now that we're not using Tiles we can no longer use Controllers, so I'm
wondering if Struts 2 has any sort of equivalent functionality. I'm
familiar with the Struts 2 Preparable interface, but I don't like this
because prepare() is always called -- even on form posts, which in my
case, is at best an unnecessary database hit (or hits), and at worst can
cause confusion with what was actually posted from the page vs. what was
retrieved from prepare().

If it helps any, we have a 1:1 mapping between an Action and a JSP,
including a naming convention: MyFavoriteAction maps to myFavorite.jsp.

Any thoughts or comments?

Thank you!!

Well, Tiles 1 "controllers" were renamed to "view preparers" in Tiles 2. See:
http://tiles.apache.org/tutorial/advanced/preparer.html

Do you have one Action with two public methods that are called by Struts
2? For example view() and submit() methods? If that's the case, I can
understand why you wouldn't want prepare() called when submit() is
called.

To solve that, just rename your prepare method to prepareView(), and it
will only run when view() is called.

If you are not using multiple public methods in one Action, and each
Action just implements the execute() method, I'd assume you have
separate Actions for viewing and submitting, let's call them ViewAction
and SubmitAction.

In this situation, make your ViewAction implement Preparable, but don't
have SubmitAction implement it.

Am I way off base here?

I personally like Preparable since the method gets called even when
there is a validation error. So you have a place to put code that you
want run both on initial display and on after a POST with validation
errors.

I have modified the EJB3 plugin(interceptor) to inject Local EJB3 beans into you action classes for Websphere V6.1 and it is working great. If anyone is interested in the code, let me know and I would send him/her the code. I was planning to send it to mailing list but my email is being rejected as spam.

I'm getting a NullPointerException when I pass a custom component as a
parameter to another custom component.

The files are:

test_fail.jsp (throws NPE):
<%@(protected)"%>
<%@(protected)"%>
<s:component template="myComponent.jsp">
  <s:param name="body">
   <s:component template="myComponent_nested.jsp" />
  </s:param>
</s:component>


test_work.jsp (works ok):
<%@(protected)"%>
<%@(protected)"%>
<s:component template="myComponent_nested.jsp" />


myComponent.jsp:
<%@(protected)" %>
<%@(protected)" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
<html>
<body>
  <s:property value="%{parameters.body}" escape="false" />
</body>
</html>


myComponent_nested.jsp:
<%@(protected)"%>
<%@(protected)"%>
<p>Some text...</p>
<s:form namespace="/" action="index" method="post">
</s:form>


As you can see I'm passing the component myComponent_nested.jsp as a
parameter to the component myComponent.jsp. That fails if any struts2 tag is
used in myComponent_nested.jsp (if I don't use any struts2 tag it works).
The component myComponent.jsp works ok if I pass a string instead of a
myComponent_nested.jsp.

The stack trace follows:
