Re: Help PLEASE!!!! How do you create struts template file using frame instead of table
Hello Anh, In the template page, you have to write something like : --- " name="header" > " name="body" > " name="footer" > -- The scriplet <%=request.getContextPath()%> is not mandatory, but it allows to put relative URL rather than absolute URL in the insert tag. Thus, your page are portable on different sites. Your insert tag looks like : -- - Don't forget direct="true" ! This instruct to output the string as is, rather than trying to include a jsp page.

The 'scope' attribute does not apply to the element. It applies
only to the element, as you use it below.
It seems odd that your form is under the Struts package, but it won't cause
any problems.

This looks OK. When doSomeAction.do is invoked, Struts will look for an
instance of your form in the session, under the attribute name "myBean". If
it does not find one, it will create a new one for you. It will then
populate the bean with the values from the request.
> So in ProcessMyBean class, i instantiated object MyBean with:
> MyBean mb = new MyBean();
> and then i called the getter to get the value which was set before:
> (here is somewhat i am missing)
I think this is where your problem lies. You should not be creating an
instance of your form bean. Struts will do that for you, and call the
appropriate setter methods based on the query string for the request. The
form bean will then be passed to your action's perform() method, and you can
call the getter methods as necessary.
Hope this helps.

Re: beta 2
Beta 2 is still under development, which is why it's not available for download yet. The release notes are there, I believe, as a "running commentary", if you will, on the changes that have happened so far between Beta 1 and the current nightly builds.

RE: using struts in a load-balanced environement
Hi Doug, If you do not require cookies and you want clustering to be effective, then the app server/ servlet container you choose will have to embed the server specific information into JSESSIONID parameter. You would then load balance to any web server that has a plug-in which can decrypt the parameter and redirect the request to the server housing the session variables for that user. You have to be careful when selecting an app server because most require cookies for clustering to work effectively. --Abraham > -Original Message- > From: Doug Wright [mailto:[EMAIL PROTECTED]] > Sent: Wednesday, March 28, 2001 4:50 PM > To: [EMAIL PROTECTED] > Subject: using struts in a load-balanced environement > > > I am very curious about whether the struts framework could be > applied in a 'load-balanced' or 'webserver-farm' environment.

ActionServlet will take MyBean from 'session' scope (put there by
tag) and populate it with the form parameters before calling
ProcessMyBean.perform().

RE: Communicating with EJB's from Action
Chris, What we've done is this: - Put a layer of business logic session stateless beans above the entity EJBs. The beans in this layer have methods that perform specific business functions. - Have the Action classes translate the user's click into one or more calls to the business logic layer. We don't pass the ActionForm to the business layer, because the ActionForm is too close to the view. If we need to pass a set of related data items to the business layer, we do it with a value object that represents the kind of businessy attributes you'd find in an EJB. So, we partition responsibility like this: JSPs: rendering. To us this is View. Actions: translation of user actions into business operations (if necessary) and always a decision about what to display next. This layer doesn't implement business operations, but knows what high level business operation it needs to call to fulfill the user's request. We consider this layer to be Controller. Business session stateless beans: fulfillment of business function. For cross-entity operations, do the details here. Speak in only business terms, not in any view terms. Completely independent of Struts. Still Controller for us. Entity EJBs: Fulfill single-entity business operations here (like basic value checking of attributes). Of course, these EJBs also give us all the entity-bean function we get from the container. Only this layer knows about the database. In general, we don't let an entity EJB interact with another entity EJB; we leave this to the session stateless beans above. This is our Model. Utility classes: ActionForms - for passing view-specific information around between Actions & JSPs, etc. Value objects - for passing entity-specific information around, including up to and down from the Actions.

Re: Communicating with EJB's from Action
How about a slight variation on #1?
interface BusinessBeanThingie {}
class YourActionForm implements BusinessBeanThingie {}
class YourSessionBean { YourSessionBean(BusinessBeanThingie bbt) {} }
Because YourActionForm implements BusinessBeanThingie, you can pass it
to your session bean in your perform method just like your first
alternative. However, YourSessionBean is no longer dependent on
YourActionForm; it's not even dependent on Struts! You end up trading a
little more work (creating the business interface) for a less tightly
coupled -- and therefore more reusable -- Session bean.
Personally, I don't like passing containers because it's not obvious
from the code what they contain. I've had good success with the
interface approach, though. Good luck.

RE: beta 2
Hello Struts Users, I am fairly new to struts (like a lot of folks), and was fairly confused by the duplicate tags in the struts.tld and other of the struts tag libraries (e.g. struts-bean). I finally saw in the release notes for the beta 2 that this entire tag library is deprecated. Why is there a link for the release notes for 1.0b2 (beta 2), but not a link under Acquiring struts to download the beta 2? J. Darren James [EMAIL PROTECTED]

Re: need some explaination with logon.do
First, be sure that you have followed the "tour" that comes with the example. There's a small link on the first page. The "do" pages are "action mappings". When the Struts ActionServlet is registered with the container, it asks for the "do" pages. The ActionServlet then refers to the mappings defined in the struts-config file to call the appropriate Action class. The Action class is not really a page, but it does have access to the ActionServlet, and so can create a HTTP response, or forward control on to a JSP. "Charlemagne L.

Hello everybody, I currently have the 1.0 version of struts. I tried to look at the examples and studied it.

Communicating with EJB's from Action
Hello! :) Our dev team for a big enterprise app has been going back and forth on how to send the data from the ActionForm to a Session bean. We have a number of options and I was hoping for some feedback because we've had enough talk and its time to decide! :) (Our architecture is as of now to use only Session Beans, but we will probably start wrapping Entity beans with Session beans eventually). 1) Send the ActionForm to the EJB from Action perform() Pros: Easy and less work Cons: Defeats the purpose of Struts in that the Business Logic is no longer self-contained and independent of the V in MVC :). If for whatever reason we overhaul the front end and remove Struts, we're not in the ideal position to do so. 2) Create a special utility class that with special methods, that when invoked from the Action perform() method, will put the data from ActionForm into a HashTable. Then, we'll pass that object to the EJB and do whatever business logic is necessary. 3) JMS - Sort of an adaptation of the number 2 as JMS uses HashMaps and the like but it follows a specific spec and has a lot more to it then what we'd be doing above. However, none of us really know much about JMS yet. :| Obviously we can learn, but is it a recommended path to follow from your experience? (in regards to Struts specifically as well). 4) RMI or RMI-IIOP. Create a remote object within the client and pass the remote reference to the EJB. The EJB can then use this reference to make callbacks to the client. Not sure about this one either, seems rather inefficient. Oh, and one other question, since DataTable (Java collection) is basically made up of vectors, can one use the iterate tag to move through it? Any thoughts or experiences?? :) Thanks, Chris Assenza

My problem is that i don't want to write the 'undefined.jsp' in each You can specify an 404 handler page for the servlet engine (web.xml). You can set up your forwards with the real (non-existent) pages and you can write your 404 page handler as you think is best for your purposes to embed most smoothly into your current env. It is Quite similar then your current situation but you use rela page names, and add up navigation, parameters, skin to the error page mimicing that it belongs to your app. icnze

Re: .properties file
Yes, you can put anything into your application file (jsp file name, image file name, and text file name). The problem is who will read it?

Does anyone have a code example for validating a date field in the validate method of actionform? Actually, a date in a string attribute. thanks in advance for your help, Donnie Hall
Re: form bean question
Eugene, If I have understood your question, the 1st place is jsp file, where the form is directly used. The 2nd place (config file) where you set mapping up. For example you tell that logonForm (the first letter is lower case) is coming from the class LogonForm, and jsp file logon.jsp will be called if the server needs to access the form logonForm.

Hello everybody, I think I still don't understand how did the struts-example flows. Could anybody please give me an explaination of what is happening to have the virtual page logon.do? Who created this page? How this page come-up? It is here where I am stocked up with my learning of the Jakarta Struts. Any help will be greatly appreciated. Thank you. Charlemagne Rey

variable number of fields in a form
Forgive me if this has been asked; I'm having trouble reading old messages. Within a page, I need to show a variable number of rows (each of which represents a database row). Each row will have a text entry field. The user can enter values in any number of these fields before submitting them all with a single button click. Is there a way to use an ActionForm for this task, other than to hard code the maximum number of fields into the ActionForm? (If not, I supposed I can still have the Action sift through the request to find the values.) Thanks, Steve

Re: standard administrative actions?
Use the source, Luke, use the source. ;-) Just as an aside -- Struts "digests "the Struts config file when it loads, using it as a "script" to create the mappings. At runtime, Struts refers to the mappings (loaded in memory) -- not to the actual configuration file stored on disk. (Hence, the need for the reload administrative action.) These actions do the same thing -- they affect the mappings stored as a protected property of the ActionServlet.

dropdown values gone after validation error
I have the following struts/JSP fragment that creates a dropdown with values from the networkTypes attribute. The networkTypes attribute is created in the "getNetworkTypes" action that displays this page. The page displays correctly initially. But if I have a validation error & the page reloads, the networkTypes variable is empty & I end up with an empty dropdown. Any ideas on how to keep from losing the values in my dropdown after a validation error? Is there any way to re-invoke the "getNetworkTypes" action from the Validate() method on my ActionForm descendant? (Maybe forward to the "getNetworkTypes" action & return null in Validate?) Any help would be appreciated. Thanks. Wayne [EMAIL PROTECTED]

Re: iterate tag
It looks to me like LanguageBean has a method call langCollection that returns your collection. If this is true the tags should be like this. The will loop through each element in the collection.

Re: How to redirect to the input jsp page from the formbean's validat emethod instead of populating ActionErrors.
Hi Senthil, Sorry for answering a question with a question. How do you redirect errors from perform to the input page without ActionErrors? Best regards Suresh "Suriyanarayanan, Senthil Kumar" cc: Subject: How to redirect to the input jsp 03/29/01 06:39 AM page from the formbean's validat e method instead Please respond to struts-user of populating ActionErrors. Hello, How do I redirect to the input jsp page from the formbean's validate method instead of populating ActionErrors. I knew redirecting from the perform method of the Action object, wondering is it possible to simulate the same from the validate method.

Re: init'ing a session bean in Action
what you have to lookup is the jndi name. I am using Weblogic and I have
a weblogic-ejb-jar.xml where you say the name you want to put to EJB in
jndi directory.
namexxx
ConfigHome home = (ConfigHome) ctx.lookup("namexxx");
Bye
