Javascripting
Hello All,
I am facing problem in using javascript.
The cases:
1) I have a select box.
2) OnChange a javascript method is called.
3) In this method a Form is submitted and an action class is called.
4) on finishing with the action class same jsp is called.
Problem::
5) if now again step 2 is repeated I am getting the error object not found??
On seeing the URL of the page before submitting it was a jsp page and after submitting it is a .do page.
Please help me with it.

Hi,
Do you have specify the Tiles plugin in your struts-config (struts1.1)
or the appropriate ComponentActionServlet (Struts1.0.x) ?
More answers intermixed.

beanName attribute is used to specify to get a definition stored as a
bean in a jsp scope. Definitions declared in a config file aren't store
in such scope. They are stored in the definition factory. You should use

You got it because no bean can be found under requested name.

This is consistant with what I have said before. There is no such bean
in the request context.

Re: in ActionForward.perform()
Posted by Roland Carlsson <ro...@swetravel.se>.
Hi again!
I think I have got some progress in the subject. I found the
org.apache.struts.webapp.tiles.template.DynTemplateAction and with that as
model i added a page looking like this:
--------/layout6/page2.jsp--------------
<%@ taglib uri="/WEB-INF/struts-tiles.tld" prefix="tiles" %>
<tiles:insert beanName="test.page" >
</tiles:insert>
-------------------
So now my action looks like this:
------------------
<action
path="/layout6/page"
type="layout.BodyChangeAction" >
<forward
name="success"
path="/layout6/page2.jsp" />
<forward
name="error"
path="/layout6/error.jsp" />
</action>
-------------------------
I get the following exception:
------------------------
javax.servlet.ServletException: Error - Tag Insert : No value defined for
bean 'test.page' with property 'null' in scope 'null'.
-------------------------
I also tried to request.getAttribute("test.page"); but it returns null so to
me it seems like request.setAttribute("test.page", defintion); doesn't reach
page2.jsp??
Other info:
------/layout6/page-defintion-------------
<definition name="/layout6/page" page="/layout6/layout.jsp" >
<put name="header" value="/layout6/header.jsp"/>
<put name="footer" value="/layout6/footer.jsp"/>
<put name="menu" value="/layout6/menu.jsp"/>
<put name="body" value="/layout6/body1.jsp"/>
</definition>
----------Source of my action -----------------
String forward = "success";
String path = request.getParameter("body");
// Change nothing
if(path == null || path.equals("")){
// do nothing
}else{
// Try to change body-page
ServletContext context = this.getServlet().getServletContext();
ComponentDefinition cd = null;
try{
// Get the name of the defintion from the URI
String definition = request.getRequestURI();
definition = definition.substring(0, definition.lastIndexOf('.'));
// Create new definition from and existing
cd = new
ComponentDefinition(DefinitionsUtil.getDefinition(definition, request,
context)) ;
// Alter the definition
cd.putAttribute("body", path);
// Put the definition where the page can find it
DefinitionsUtil.setActionDefinition( request, cd) ;
request.setAttribute("test.page", cd);
// if something is wrong
}catch(Exception e){
e.printStackTrace();
forward = "error";
}
}
return mapping.findForward(forward);

Re: in ActionForward.perform()

Hí!
I have tried but I missed something.
I'm using the code below to alter the definition with the following request
http://localhost:8081/layout6/page.do?body=/layout6/body2.jsp.
I put the defintion into the request but I have a feeling that I need to do
something more. Now I just come back to the original definintion.
---------------------------------------------------
// Get the name of the defintion from the URI
String definition = request.getRequestURI();
definition = definition.substring(0, definition.lastIndexOf('.'));
// Create new definition from an existing
cd = new
ComponentDefinition(DefinitionsUtil.getDefinition(definition, request,
context)) ;
// Alter the definition
cd.putAttribute("body", path);
// Put the definition where the page can find it
DefinitionsUtil.setActionDefinition( request, cd) ;
// Put the definition into the request
request.setAttribute(definition, cd);
.
.
.
return mapping.findForward(...);
--------------------------------------------------------
<action
path="/layout6/page"
type="layout.BodyChangeAction" >
<forward
name="success"
path="/layout6/page" />
<forward
name="error"
path="/layout6/error.jsp" />
</action>
-----------------------------------------
<definition name="/layout6/page" page="/layout6/layout.jsp" >
<put name="header" value="/layout6/header.jsp"/>
<put name="footer" value="/layout6/footer.jsp"/>
<put name="menu" value="/layout6/menu.jsp"/>
<put name="body" value="/layout6/body1.jsp"/>
</definition>

Re: in ActionForward.perform()
Posted by Cedric Dumoulin <ce...@apache.org>.
The context is the tile context. It is associated to current tile, and
created when you insert the Tile, or forward to a tile. So, it doesn't
exist if your action is called throw the normal Struts way. But, you
don't need the context to get a definition from the factory and put it
in the request scope in order to be used by the struts forward.

Ok. so far I have got it but I still doesn't get the request into context.
ComponentContext context = ComponentContext.getContext( request );
returns null so I having a hard time to test the

What is wrong when ComponentContext.getContext(request) returns null? I
doesn't get any help from the documentation here.

Ok, I haven't read carefully enough your previous mail.
You can create a new definition from a definition read in the factory,
and then instruct current Struts action to use your new definition. More
precisely, the definition associated to the struts forward will be
overloaded by your definition.
The class org.apache.struts.webapp.tiles.test.TestActionTileAction use
in the tiles-documentation/test do that.
Following is an extract from this class. The code get the definition,
copy it, modify the copy, and then put it in the appropriate request
attribute. The
// Read definition from factory, but we can create it here.
ComponentDefinition definition = DefinitionsUtil.getDefinition( ... );
definition = new ComponentDefinition(definition);
definition.putAttribute( "attributeName", "aValue" );
DefinitionsUtil.setActionDefinition( request, definition);
...
return (mapping.findForward("success"));

Re: in ActionForward.perform()

Hi !
I think the DefinitionDispatcherAction doesn't do what I want to do....
Imagine that you have a definition with 2 tiles (left and body)
In the left tile there are a collection of links that will change the
content of body.
If I understands what the DefinitonDispatcherAction does it will change what
defintion to use. What I want to do is to change one tile in the defintion,
much like a frameset where i doesn't change the frameset, only one page in
it. So I want to call the same defintion and alter a tile in that defintion.
Not change the defintion.
The problem with the perform-method I posted is that it change the tile in
the application-scope and I havn't figured out yet how to make the change
isolate into a request only.
Regards
Roland

Ok, I'll take a look into that one. I found out that my Action did last over
requests... witch it isn't supposed to do. :-( So I'm back to square one.

Hi,
I think there is an action in the Tiles/Struts distribution doing
exactly that ;-)
Check org.apache.struts.tiles.actions.DefinitionDispatcherAction.

I have solved my own question. If anyone is intrested I past the code below.
The change in the definition lasts only for the request and will not make
any permanent changes.
Regards
Roland Carlsson
public ActionForward perform(
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException
{
String forward = "success";
String path = request.getParameter("body");
// Change nothing
if(path == null || path.equals("")){
// do nothing
}else{
// Try to change body-page
ServletContext context =
this.getServlet().getServletConfig().getServletContext();
ComponentDefinition cd = null;
try{
cd = DefinitionsUtil.getDefinition(path, request, context) ;
cd.put("body", request.getParameter("body"));
// if something is wrong
}catch(Exception e){
e.printStackTrace();
forward = "error";
}
}
return mapping.findForward(forward);
}

Hi!
I'm trying to expand my tiles with a dynamic body. I want to control this
body with a simple parameter in the url eg
http://localhost:8081/myPage?body=aTile.jsp . Does anyone have an example of
