Re: Struts 2 : application-wide values initialization.

2007-09-08 Thread Leonidas Papadakis

You can do the same with an application scope bean using spring . Create 
a simple pojo that initializes values on the constructor. Then add an 
entry to the applicationContext.xml file :


beans
   bean id=myComp class=org.components.MyComponent singleton=true/
/beans

Then in your java action file that you wish to have access declare :

private MyComponent myComp;

and create a setter :

   public void setMyComp(MyComponent myComp) {
   this.myComp = myComp;
   }

Now you can get and edit these default values from your action.

I do not know if this is the best way to do it and please excuse if i 
have any typing mistake (it should be fine though...).

In Struts 1, we were having an init servlet to load the application-wide

context and accessing these within JSP. Is there a better way of doing


this in Struts 2, and do we require an initialization servlet at all ? .
  


The ServletContextListener is called when the ServletContext is
starting up and shutting down.  It's designed to let you do one time
configuration and initialization.  You have access to the
ServletContext so that you can put things in the Application scope.
Sorry, I thought that's what you were asking for.

Re: Struts 2 : application-wide values initialization.

2007-09-08 Thread Gabriel Belingueres

Another option is to subclass the Struts 2 FilterDispatcher to perform
initializations:

public class YourAppDispatcher extends FilterDispatcher {
  public void init(FilterConfig filterConfig) throws ServletException {
super.init(filterConfig);
// your initialization code here...
  }
}

Re: Simple Question about FreeMarker + Struts 2

2007-09-08 Thread Zarar Siddiqi

Freemarker considers null references errors.  When
myActionProperty.subProperty is referenced in the Struts tag, it is
printed regardless of its value.  However, when Freemarker encounters
${myActionProperty.subProperty}, it will give you an error if
subProperty is null.  When trying to print Freemarker variables using
the $ or # syntax, you should probably do an if check like this:

# if myActionProperty.subProperty?exists
  ${myActionProperty.subProperty}
/#if

I know, it's a bit of a pain.

 Is there any good documentation on using FreeMarker in Struts? I can find

 can't find any docs or tutorials on using the two together. Any suggestions?

 PS for the record, I think it's just that I'm not finding the documentation
 intuitive. For instance I figured out how to prevent the struts form tags from
 outputting HTML table tags but I had to use a search engine. I tried setting 
 the:

 struts.ui.theme=

 but that was obviously not the solution. My problem was that I wanted to turn
 the 'themes' feature off. But you don't turn it 'off' - you just turn it 
 down. It's:

 struts.ui.theme=simple

 Maybe a line in the taglib docs would make it more obvious?

2007-09-08 Thread Jim Cushing


Some other things you can use:

${myActionProperty.subProperty!}
Prints nothing if subProperty doesn't exist  or is null

${myActionProperty.subProperty?default(default value)
Prints default value if subProperty doesn't exist or is null

The first expression (ending with !) is most similar in behavior to  
the @s.property / tag.

Struts2 with AJAX

2007-09-08 Thread animesh saxena

Hi,
   I am using a very basic AJAX code snippet with struts. No it's not
dojo. 

req = new XMLHttpRequest();
var url='http://localhost:8084/StrutsAjax/example/SearchAJAX.action';
req.open(POST,url,true);
req.onreadystatechange=searchResults;
req.send(null);   

in searchResults() function I just wnt to see req.responseText;

If I want to return some response from server side if I use something
crude like this

response.getOutputStream().print(htmlAnimesh/html);

It messes up struts and I get lots of exceptions in responseText.

I want to return some string from the server side which is accessible by
javascript code. It can be JSON or anything.

What should be the code on server side / my action class (execute
method) to return something to client side? Any suggestions??



Thanks,

Animesh

Man oh man that is going to fry the algorithms in my poor JSP editor, even if it 
could cope with the stuff I force-feed it at the moment (which it doesn't).


Isn't there a non-OGNL way?

2007-09-08 Thread Nuwan Chandrasoma


Hi,

In your action class you have to return null after you write the 
response for eg:-


 public String ajax() throws Exception {

 respone.getWriter().println(hello);

 respone.getWriter().close();

 return null;

 }

and also i dont think you need to specify the full URL when you are 
doing the ajax call.,


Thanks,

Nuwan
