Formless actions

[Pierre Métras]

Hi,

I have to code a menu. Depending on the user interaction, different features
will be executed. These features are Struts actions *.do URL with associated
JSP files for the views. The menu is included on all the forms.

Should I use an Action class to manage the menu processing, knowing that no
input form will be associated with it? So the mapping will look like:

  
  
  



Using the Struts design has the advantage that the foward mapping allows to
use logical names for the features. This indirection level allows to add or
modify a feature without impacting the others (just place a ).
On the other side, Struts mechanic is a bit heavy for a servlet whose role
will be to forward to another feature based on a request parameter, that's
to say a big sequence of if-else.


Subsidiary question:
I have a menu option that is used to switch the language used for display,
and then return to the calling feature.
Can the menu know from which feature it is called, without having to add
another parameter in the request? Is the Referer header available in that
case?

Any opinion welcome.

Orion and Struts 1.0 (once again)

[Till Nagel]

Hi,

I am trying to use Struts 1.0 (20001115) with Orion Server 1.4.

If I use the struts-config.xml with validate=true in the web.xml the
following exception occurs:
  java.net.MalformedURLException: unknown protocol: jndi

Okay, no prob. I deleted the validation in web.xml so at startup it uses the
"system identifier" and gets the DTD via the
http://jakarta.apache.org/struts/dtds/ link. (You could change the URI to
your local drive, if you are a using a dial up.)
After that it can read the struts-config.xml correctly. But if I call my
action ("myhost/showNews.do") I just get a message saying "Invalid path
/showNews was requested".

I appreciate any advice.

Regards,
Till


new dtd (struts-config.xml):

  


log file:
24.11.00 22:25 neteye-web: org.apache.struts.action.ActionServlet:
Processing a GET for /showNews
24.11.00 22:25 neteye-web: org.apache.struts.action.ActionServlet:  No

The bug doesn't bite everyone -- whether or not your struts-example gets shut
down correctly or not depends on what other web apps are defined in the same
Tomcat installation (technically, it depends on the order in which the web apps
are enumerated in a Hashtable, plus which JVM you are running).

At any rate, the only damage this bug does is it will fail to save any changes
to the "users" or "subscriptions" that took place.  The application itself still
works OK.

Of course, as others have pointed out, this is only an example app anyway -- a
real system would use a database.  I just wanted something self contained, that
would run "out of the box" in most circumstances.

RE: need some explanations

[Vilavanh Messien]

If I understand, destroy() should be called when the servlet container (i.e
Tomcat) is shutdown.
But, in my small application, destroy() seems not to be called so that
information cannot be
written database.xml.
I didn't manage to find where my error is.

The destroy() method is called by the servlet container, when it removes
this
servlet from service or when the application is shut down.  Typically,
server
shutdown is the *only* time that a servlet is removed and destroy() is
called.

This is done by adding  entries in the WEB-INF/web.xml file.

it at:

Are you thinking that the "plugins" will be plugged into ActionServlet?  If so,
you've still got the same issues as with DatabaseServlet, because the servlet
container is entitled to throw out your ActionServlet instance if it wants to.

In the servlet 2.3 API, there is a new feature called "Application Event
Listeners".  You can register (in web.xml) a particular class as a listener, and
an instance of your class will be called when the application is created, and
when it is destroyed -- completely independent of the lifecycle of the servlets
in that application.

This is perfect for things like initializing and finalizing database
connections, or any other resources that you want to guarantee you have
available for the entire lifetime of your app.  Unfortunately, I cannot (yet)
use them in Struts because it wouldn't be supported in any of the servlet 2.2 /
JSP 1.1 containers out there.

If you want to try this new feature, I suggest you download a recent milestone
release of Tomcat 4.0 (http://jakarta.apache.org), which supports the new APIs.

Tomcat 3.1 has quite a few bugs, one of them being the use of URL rewriting when 
running behind Apache.  I
would suggest trying this with 3.2 -- you will still need the rewrite rule that you've 
described, so that
Apache knows what to do.

Yes.

Custom tags are initialized with an instance of javax.servlet.jsp.PageContext, which
provides access to (among other things) all of the attributes in all of the scopes.
Therefore, they have access to the form beans.

Re: Global resources and DatabaseServlet (struts-example)

[Mike Dunn]

Are you not worried about code breaking when container vendors take
advantage of the spec? We can define something now that will support the
current spec. I propose replacing servlets such as DatabaseServlet with the
concept of a "plugin" (hopefully, you can come up with a less overused
name):

1. Define the plugin interface:

public interface IPlugin {
void init(HttpServlet servlet) throws ServletException;
void destroy(HttpServlet servlet);
}

2. Define a plugin manager class:

public PluginManager implements IPlugin {
// list of plugins
private List _plugins;

public void init(HttpServlet servlet) throws ServletException {
// get the list of plugins from servlet's init parameters or
from a file

// for every plugin in the list, call its init method
}

public void destroy(HttpServlet servlet) {
// for every plugin in the list, call its destroy method
}
}

3. Convert DatabaseServlet and any other such servlets to plugins:

public DatabasePlugin implements IPlugin {
public void init(HttpServlet servlet) throws ServletException {
// original DatabaseServlet init code
}

public void destroy(HttpServlet servlet) {
// original DatabaseServlet destroy code
}
}

4. In ActionServlet's init method, instantiate PluginManager and call its
init method.
5. In ActionServlet's destroy method, call the PluginManager instance's
destroy method.

I don't know if you could (or if you would even want to) store the list of
plugins in the ActionServlet's init parameters because the order in which
they are initialized could be important.

Re: logic:iterate does not work with HashMap

[Jannik Nørgaard Steen]

Hi,

we looked in the Struts source code a second time. Line 283 and 284 says:

 else if (collection instanceof Map)
 iterator = ((Map) collection).entrySet().iterator();

This gets you an iterator of the *mappings* in the Map. So each element is a
java.util.Map.Entry - right ?
The doAfterBody method just put a Map.Entry in the pageContext for each
mapping in the HashMap.
So you would acutally have to do two  to get to the
value of each mapping in the entry set - one to retrieve the Map.Entry and
one to retrieve the value of the entry.

Is this the right way to do this ?

Jannik

Re: Difference between action.xml and struts-config.xml

[Pierre Métras]

Hi Koen,

Use the struts-config.xml if you want to create a new application. It's the
new version 1.0 file format used by struts. For compatibility with version
0.5, Struts can read the old action.xml file. The version you choose to use
is defined in web.xml:


  action
  org.apache.struts.action.ActionServlet
  
config
/WEB-INF/struts-config.xml
  
...

As I undertand it...

The current development release is able to use either, but from v1.0+
action.xml will no longer be supported.

We're looking at struts for a few days now and it looks good, but I was
wondering the following:
 
What's the difference between action.xml and struts-config.xml for the
action mapping? I see that in both files you nearly define the same things.
 
Can somebody explain us the difference please?
 
Thanks,

logic:equal help ?!?

[Laufer, Michael]

Title:  logic:equal  help ?!?





Hi,


I've just started with the logic-library of the Struts framework
I'm using the following code to create a dynamic html-table:



  
    
        true    
    
    
  
    
    
  
    
    
  
    
    
  
    
    
  
    
  



No I'm facing the following problem:
my
rule true   
code seems not to work correctly.
My impression is that it doesnt compare the property "isActive" with the value "true".Because I'm always getting the text "rule true" in my table.

Am I using the equal-tag not correctly or am misunderstanding here something terribly ??


Any help would be appreciated.
Thanks in advance.

Subject: logic:iterate does not work with HashMap


Hi,

we're developing a web-app currently using Struts 0.5 milestone release.
In this application we store a object in the session context that contains a
HashMap which we try to access
from a JSP. This works fine.
However when we try to iterate through the HashMap like this (contents
property contains the HashMap):


..
..


no materialItem bean is placed in the pageContext. This is odd because if we
use a ArrayList instead of a HashMap it works... but we need to use a
HashMap for other reasons.

We've looked in the iterate tag handler source code an cannot see why it
does not work.
Have we missed something or is this a bug ?

Med venlig hilsen/Best Regards
