I will add to what Dave says, and ask why you wouldn't want to extend
ActionSupport? Although extending ActionSupport may seem like you are
tying yourself to the framework, I have never had a problem because the
functionality that ActionSupport adds is only loosely coupled to the
framework. Perhaps a better way to say it is that I've never had to
create mock objects to unit test an action that extends ActionSupport.
So, a MyAction action = new MyAction(); String res = action.execute();
Will work in JUnit w/o any special housekeeping (except calling
appropriate setters). If you still aren't convinced, then wrap your
POJOs with a thin class that implements ActionSupport i.e. -

public class MyAction extends ActionSupport {

  private MyPOJO pojo;
  public MyPOJO getPojo() {
    return pojo;
  }
  public void setPojo( MyPOJO pojo) {
    this.pojo = pojo;
  }
}

Then you can name your form fields like -
<s:textfield name="pojo.memberVar" />

This way your POJOs are completely de-coupled from the framework. And,
to make things easier, you can implement ModelDriven which will allow
you to deal with your POJO directly within your form widgets. I would
add a code example, but it is all well-documented in the online docs.

Yes

Could you provide a scenario where one bean is injected into another?

That is correct, but should be highly discouraged. If your
interceptor accepted any parameters, multiple configurations would
step on each other, resulting in nondeterministic behavior.
Interceptors should also be of the 'prototype' scope.

Thanks for putting some time and effort in to help!

Flash scope is fairly common nowdays (for displaying messages) I
wonder if S2 2.011, has anything similar?

thanks,
Alex.

There is the Struts 2 Scope Plugin [1], which does flash scope and a
lot more. Also, the message store interceptor, available in core
out-of-the-box, will persist action and error messages across a
redirect in a "flash" scope, which is very handy for registering
validation errors on a POST but having the response redirect the user
to a GET.

Oh, didn't see the 2.0.11.1 requirement...not sure if the message
store interceptor code is in that branch, but the scope plugin should
work just fine.

hello everybody,
my need would be to click a link in my web page,
and to associate a variable parameter to it,
giving the possibility to the action java code to
recognize the parameter string and compute a logic
depending on its value; to be more clear, i visualize
a dinamyc number of links, one for each id reflecting a
DB query computed before to obtain the id value list, and thus, i would like to use this id as a parameter for the same action for every link; tha action should use the id parameter to compute a second query, with the id used as a key-field.

How to specify the invocation of an action passing a parameter? i mean, how to invoke it via html, and how to
read the parameter via action java code?

Thanks a lot for every answer,
Marco and Daniele

This is all what web applications are about, don't you think? :-)

You don't need to "read" parameters passed like in plain servlets,
they're injected into your action when it has the appropriate
properties (setter/getter). Take a look at the bootstrap section[1]
from the struts tutorials[2] on the homepage as a starting point, and
take a look at the showcase app, it should have tons of examples for
this.

Cheers,

The error message is pretty clear, you're missing some classes in your
classpath. The compile time classpath and runtime classpath is usually
not the same. Make sure that you have the required jar files in your
runtime classpath.

hi,

A simple workaround would be defining the bean property as String type
rather than as the actual enum.

Then use the two enum type built in operations "name()" and "valueOf()"
to implement the getter and setter respectively.

If there is actually an elegant way to do it, I would also be interested
to know.

regards,
Giovanni

Actually this is xwork-behaviour. It already provides the class
com.opensymphony.xwork2.util.EnumTypeConverter[1], which you can
simply use to convert your Enum:

xwork-conversion.properties:
foo.bar.MyEnumeration = com.opensymphony.xwork2.util.EnumTypeConverter

If you don't like the default behaviour using the Enum name() as
representation in the page, you can always write your own type
converter[2].

Cheers,

Perhaps this would be better asked on a mailing list relating to databases.

No, you want to store the path of a file in the database.

See?

That confuses me. Why wouldn't you just store the path of the file in the
database like you're saying you want to? You provided an example of it.

What are you really asking, and how is it related to Struts?
