How to call a struts action from a JSF page

I am working on a small POC that has to do with struts-faces. I need to know how to call a struts ".do" action from a JSF page..
Sameer Jaffer

is it not possible to call a action from the faces submit button and/or the navigation?
This a simple POC using struts-faces exmaples.
Here is my struts-config and faces-config file.

How to Open an Oracle Report From a JSF Page

Hi there,
I would be really grateful if anyone would find me a solution to the following scenario:
In my company, we have a project where we have to convert Oracle Forms and Reports to Java Web Application. The conversion of forms is being done thourgh JSF/ADF technology but how can i open an Oracle Report from a JSF page after supplying it with parameters ? Or i have to do some type of conversion before ?
Once again i would be thankfull for your replies.

Tapash,
Thanks for reponding.
Here is the URL I am currently using :
https://gccss.glendale.edu:8001/dev60cgi/rwcgi60?server=rep60_crp3+userid=apps/pswd@crp3+report=/u07/oracle/crp3appl/gcccus/11.5.0/reports/US/GCC_ACCRUAL_BAL_0505.rdf+desformat=html+paramform=yes+destype=cache+p_accesscode=""
The p_accesscode is the parameter I need to pass to the Oracle report.
Currently, when I click the button, it invokes the above URL and takes me to the parameter form of the Oracle report and when I enter the Username, it runs the report and displays the desired output. But, what I need to achieve is, to pass the current user who has logged in behind the scene and to get rid of the parameter screen totally. Is this doable ? If yes, please help me !!!
Thanks

How to call an exe program from the JSP page?

How to call and display the interface from a exe (residing on C: drive) on my JSP page. Our customers supplied us with an exe file and they want this to be incorporated on the JSP page that has other components also, like forms, etc. The interface of the program has to be displayed in specific co-ordinates on the JSP page. Any help is highly appreciated. Thanks in advance.

Can't be done with JSP.
JSP runs java on the SERVER only.
All that gets to client is an HTML page. So all that
you can do at the client is what an HTML page can do.
Obviously that doesn't include running a file on the
client machine.
Take a look into Applets, or maybe ActiveX controls.Thanks for the reply.
Any idea on how to use the ActiveX controls in this regard?

Can commandLink call a strut action?

Hi,
My project have existing code written in JSP and Strut framework. But, I like JSF better and would like to reuse some of the existing JSP/Strut code in JSF.
Does anyone know that whether JSF can call a strut action via commandLink
For example, the snippet below will call xyz.do, which is a strut action.
<h:commandLink id="xyx" action="xyz.do" value="XYZ" immediate="true" />
Thanks

You can indeed call a struts action from a plain form but the action needs to exist and be assigned to the specified url.

Call struts action from javascript?

Hi all
I'm having problem already discussed here quite a lot, but I have idea to solve it different way. And need to know is it possible or I'm doing mission impossible here :(
I have JSP with 2 drop down lilsts, where the second is populated according to selected value from first - that's basically my problem.
Is it possible to somehow only call my struts action which will return all needed values using javascript and onchange event handler?
I dont have any experience with javascript, and I'm trying to avoid it as much as possible at the moment.
Thanks in advance

well as far your requirement is concern if at all you are planning to implement AJAX try to use the below link which might be of some help...
http://www.it-eye.nl/weblog/2005/12/13/ajax-in-struts-implementing-dependend-select-boxes/
However,I somehow feel there are few loopholes in the author's approach...
i advice to use XmlHttpRequest.reponseXML property there.
However, i've mentioned a sample code snippet for you reference.

NOTE: I understand i'm not completely coded things as per proper coding standards.please execuse me for that as this example was just given to enable user to learn how XmlHttpRquest,reponseXML
can be used for better purposes instead of devising manual parsing.
where i've used XmlHttpResponse pattern to be in XML. you may make use of other practices like JSON & so on depending on your requirement..
and and if you are more instrested in integrating Struts with AJAX using few frameworks & customized tag based support please go though the below link.

Hope that might help :)

How to call a struts application in a portlet

How to call a struts application in a portlet. I have two different ear's. In one ear I have my struts application and in one war i have a struts portlet. In the struts portlet provider.xml defaultAction tag can i call the action class .do which in other ear (ie my struts application ear).Can anyone suggest me whether this is the right way or else can u suggest me with some other thing.
Waiting for ur responses.
Thanks and Regards,
Dhanu.

Hi Dhanu,
Your Struts Portlet will not be avialble via a URL as it is completely dependent on Oracle Portal Environment. The Provider for the Portlet is alone available via a URL - you would have registered your Portlet using the URL of the Provider.
Your Struts application, which does not rely on the Oracle Portal Environment, is defeitely accessible from a URL. It's just another web application that uses the popular Struts Framework.
Hence, you can use the URL ( the starting point - a JSP, Servlet, etc. ) of your Struts Application to "call" the application in your Struts Portlet. I don't think you need to fiddle with the parameters in Provider.xml.
Moreover, <defaultAction> in Provider.xml should have the URL of a Struts Action Class - the mapping in the
struts-config.xml should map the .do action to the right JSP file.
You can have a look at Metalink Note : 331069.1 for a good insight into the <defaultAction> Tag.

Sandeep

How to to get Struts Action at very first loading

Hi, All;
I was working on Jsp with Struts framework, I do not know how to get the Struts action to run during the very first loading if it is no submit buttons.
When first load of page, I'd like to retrieve data from Action class (or other class) with request, then drop it to request attributes or create a bean.
Because, normally Action class will be invoked in submit on page form which predefined in config files, but my page should get data from class with request at very first loading (without button submit), so can anyone know the way to do this kind of things? Is there other thing need to do in strust-config.xml. I really appreciate your ideas or examples.

Sure. In the url just call that Action's path (e.g /app/myAction.do) which will first fill the data and then send to the desired JSP.
Click Here
When the user clicks on the link the Action would be automatically called. And you can do whatever you need in the Action.

How to call a j-frame from a main frame

I use both NetBean 5.5 and Forte for Java4
i would like to know how to call a j-frame from a main jframe window when a button is clicked after
action performed or moused clicked is set
i.e Main jframe (window) has a button ---> (grades) click it
should open the sub-jframe named grades with all the grades showin in that frame
your help please thanks

It sounds as if you want the button to open a dialog that displays your data such as a JOptionPane and not a JFrame.

Ralph

Hi,
Basically, I would like to call a method that I have written in the page java bean, or in the session bean, or application bean, or an external bean, from the javascript events (mouseover, on click, etc...) of a ui jsf component. I.e., I would like to take an action when a user clicks in a column in a datatable.
Cheers,
Ralph
