Howto struts on OS/390??
Hi, we would like to run a struts 1.01 web application on an OS/390 computer. Is there a howto available (Websphere 3.5.x /tomcat) because we have difficulties with Webpshere 3.5. Is tomcat possible? Who has any experience?

Re: Request: Property vs Attribute

You might want to start with an ActionForm bean that represents the OK

This should include properties for a base forward and for a paramId and

ActionForward baseForward = mapping.findForward(okForm.getForward());

something like

Hi Ted,
thanks for the suggestion.
I've implemented it, but I faced the difficulty to get the info
into the form in the first place. I mean I am in an Action class and
want to direct to the okdialog. The ActionForm doesn't exist yet, right?
My solution is to set those infos (forward, message, paramId etc) as
request.attributes. In the validate method of the form I do sth like
if (forward == null) {
forward = (String)request.getAttribute(forward);
}
if (message == null) {
message = (String)request.getAttribute(message);
}
Would that be ok or are there other ways ?

Re: struts.jar outside of WEB_INF/lib on Tomcat4?
I've often heard that you can't put struts.jar in CATALINA_HOME/lib but I've never heard anyone say why it doesn't work. Is it a bug?

My problem is that the struts-based webapps only seem to work if struts.jar is in WEB-INF/lib, but my utility class requires it to be in %CATALINA_HOME%/lib.

Re: Datetime validation taglib for struts?
Transformation mechanism for binary data, taking the date example. Trying to deal with java.util.Date in Struts I have came to look for : 1. Validation mechanism I tested the Struts Validator Ted mentioned. Centralized xml config, 18n support, out of the box JavaScript for client side checks, ... great ! 2. Transformation mechanism I am looking for a way to benefit from java.util.Date automatic population in ActionForm like Strings or primitive types are. 2.1 The actual properties conversion takes place in org.apache.commons.beanutils.ConvertUtils this might be extended to support java.util.Date conversion. 2.2 Thanks to the Struts Validator it seems there is a generic way to know which date pattern is used for which field at submission time. The ActionServlet or as proposed (...). A transformation plugin to the Validator (...) could exploit this to do any required request parameters pre-processing to let ConverUtils always receive dates of a similar pattern. Do you think this could lead to a solution ? Patrick Ted Husted wrote: The domain-type validations, like whether it is a date, can be handled in the ActionForm validate, if that's helpful. The Struts Validator is very good for this, and keeps everything out in an XML file where it can be easier reviewed. Range checks that depend on the model state would still have to be performed in the action, though. A lot of it depends on what you already got. If the model beans already do the validation, let them. If they don't, do what you can in the ActionForm. Transformations are trickier. I don't have a really good solution for transforming binary data. There are some tools, like Rey Francois' mapper, but I haven't put them into a production app myself. For properties representing formatted binary data, I tend to have getDate (binary) and getDateText (string) properties. The action sets the binary property, which in turn also sets the String field. The form sets the String property (property=dateText), which also tries to convert it into a binary. If it fails, the binary field goes to null, but all exceptions are caught. Otherwise, it updates the binary field. The validator can then look at whether dateText and/or date are empty, and post the appropriate validation error (if any). The methods in question rely on static methods in a utility class, to eliminate as much unique code from the action form bean as possible. When the form gets to the action, the model bean can get it's value from the binary property. Since I tend to use reflection for this, I use the real property name for the binary version, and append Text for the formatted for display version. The same approach can be used for String fields like telephone numbers, where you might want to store only the digits, without any punctuation. The telephoneText property copes with hyphens and spaces. The telephone property is a string with all digits. This is probably the most common approach right now, but it's a pain to setup. It also means that properties are sharing fields, or else you at least need a setDateTextRaw() property to avoid looping. A transformation plugin to the Validator that could be configured with XML would be much better. -- Ted Husted, Husted dot Com, Fairport NY USA. -- Java Web Development with Struts. -- Tel +1 585 737-3463. -- Web http://www.husted.com/struts/ [EMAIL PROTECTED] wrote: Thanks Mark for your answer.

RE: Form - Bean conversion - Not getting values
I apologize for not getting back to you sooner.
I realized that as I began responding to you last post, my response was
quickly becoming a full blown tutorial on wizards in struts.
I think I'll publish a tutorial on my web site in a few days, but for
now here is a summary what I wrote
If I understand correctly:
1. You are trying to persist input values across multiple
pages (such as a 3-step-wizard might do)
2. You are wanting to reuse existing bean classes within struts framework
(perhaps and Entity Bean???)
**Requirements - User must be able to hit next and previous (submit buttons
on page **Not Browser buttons**)
and system should maintain state across pages. (Without using session or db
persistence)
I have written several wizards in struts and I have found that
the best way to handle the persistance (on the servlet container side) is to
create your wizard in such a way that you use the same jsp and same action
class
for each step in the process. Just use a different section of the page.
(Separated by logic:equal tags)
Doing this will:
1. Allow you to have better consistency across your pages (look and feel)
2. Allow for Code reuse (my personal favorite)
Lets assume this is a 3 step wizard.
Step 1. - fill in first name and last name
Step 2. = fill in address
Step 3. - check an I agree on a terms page.
The ActionForms/Beans and fields we want to use are as follows:
(assuming they have accessor methods implemented)
com.mybean.MyActionForm
boolean agreed
com.mybean.MyExistingCustomerBean (could be an Entity bean)
String firstName
String lastName
String address1
String address2
String city
String state
String zipCode
Be sure to expose all fields into the html output (even if it's not used,
just put it in a hidden input tag). Doing this will
persist your ActionForm and Bean fields from step1 to the end, and allows
the user to hit previous and back submit buttons.
-
--
I'm not sure how you want to validate the ActionForm or Bean class at any
given step, but:
1. Change the ActionForm scope to request
2. Add a field in your ActionForm called step and put a hidden field in
the jsp named step.
3. Put two submit buttons (each named action) in your jsp page (one is
Previous and the other is Next
So when you are in the action class you will know where you are coming from
by getting the form.getStep() and you will know where you should forward
to by getting the form.getAction().
Therefore:
if ( form.getStep().equals( 1 ) ( form.getAction().equals(
Next ) ){
form.setStep( 2 );
}
if ( form.getStep().equals( 2 ) ( form.getAction().equals(
Next ) ){
form.setStep( 3 );
}else{
form.setStep( 1 );
}
// if the action is not Finish then forward to next (see action mapping
forward below)

RE: Showing a result after a long running query
Ahhh, the long running query problem. Yes its a classic. I agree with Michael though. The answer to your dilemma has nothing to do with struts, java, or anything else on the server side of the application at all. This is a limit of web technology in general. I've written a few applications that handle similar opportunities (my friendly name for problems). In one case, the user created downloadable files that were extracted from a DRP system (KBM on AS/400 DB2). The challenge was how to create the file and let the user download it all from the web. What I ended up with was a Crystal Reports-like web application, where the user used a wizard to create the initial parameters that were passed to an asynchronous process that ran in the background and updated the db when it was finished. The user just had to sit back and wait for the extract to finish. They could refresh the page of processing jobs all they wanted, but it wouldn't let them download it until it was finished. You might try creating some summary tables for common long running queries, if you are reporting summary analysis. This technique has helped me eliminate the need for my Crystal Reports-like app on my current project.

This lets me decide at deployment time whether the user sees a login or the main menu. my index.jsp has a request. - index.jsp % pageContext.forward( /index.do); % - struts-config.xml action-mappings action path=/index type=com.xyz.IndexAction forward name=login path=/index.do?action=login/ forward name=main path=/main.do/ /action action path=/login type=com.xyz.LoginAction scope=request name=userView validate=true input=/index.jsp forward name=login path=/login.jsp / forward name=success path=/mainmenu.jsp / forward name=failure path=/index.jsp/ /action action path=/main type=com.xyz.MainAction input=/index.jsp forward name=success path=/mainmenu.jsp / /action James Mitchell Software Engineer Open-Tools.org Home Phone (770) 822-3359 Cell Phone: (678) 910-8017 -Original Message- From: Tim Sawyer [mailto:[EMAIL PROTECTED]] Sent: Saturday, February 16, 2002 6:49 PM To: Struts List Subject: Action Forwards Hi, There's nothing to stop me forwarding to a do rather than a jsp in the struts config is there?

FOP and strus
Hi, I am looking into FOP in generating PDF in struts... the examples so far that I have seen are only taking static XML files and XLS files. Can someone tell me how to use FOP to generate pdf with dynamic XML string (generated by some java objects) on the fly? I would apprecaite if you could even provide me with some sample code.

Re: FOP and strus
John, We wrote a servlet that took the name of a URI as a parameter. That URI, essentially mapped to a JSP, whose output was FOP. The servlet: requested the URI, got the FOP, formatted the FOP, then sent that back to the browser. This may not be ideal for all situations, but it worked nicely for us. You could look at using something like webmacro/velocity as it would be neater than a JSP for this. It depends on what you are doing.

Mapped properties - How To
The mapped property feature is extremely useful, although somewhat elusive.
I've been struggling to get this feature to work, and after spending more
time than I would care to admit trying to figure it out, I thought I would
share a simple how-to on the matter since I ran across several messages in
the archives from people who had similar challenges.
First, I grabbed a nightly build of struts (Feb 15, 2002).
Second, I added an input tag similar to this in my .jsp page:
input type=text name=item(color) value=blue
Third, I added the following two methods to my form bean (note: it's
important to have the get method, even if you don't plan to use it):
public Object getItem(String key) {
}
public void setItem(String key, Object value) {
}

Re: Mapped properties - How To
Sorry to say, it's not going to work. There's a bug in the PropertyUtils
class that makes it happen.
You could do some collection tricks and get it coming out in an Array,
and that would work, but not the mapped property.
