Re:[PARTLY SOLVED] workflow - Re: integration with other app
Okay.. the back button going to the prior screen.. you'd think i've never done webapps before.. my no-cache headers were missing. that's resolved. I've begun to grok the workflow pattern a bit more, and here's what i've come up with I was picturing the overall task as a workflow. However, if you look at each discrete unit of work in the entire task, each unit is actually its own workflow. And, the pieces/steps of that unit are what you should use to define individual "workflows" in the sense of the extension. Ergo, task 1 has steps 1, 2 and 3. which gives you workflow1, workflow2, and workflow3. each workflow should likely have 2 steps: display the page (enter the workflow), and submit data from that page (end of workflow). along with these 2 steps, there is also a possible workflow violation, which, ideally, should flow you to the 'display the page' step. Each end(termination) of a workflow's primary flow will lead into the next step's 2ndary workflow chain. granted, this is a very simplistic overview, and not applicable for all tasks.. but, it's a nice foundation step that wasn't readily obvious in the documentation (or I was just being horribly dense). So, have I grokked this properly ? Is there something else I"m missing? -- adam - Original Message - From: "Adam L" <[EMAIL PROTECTED]> To: "Struts Users Mailing List" <[EMAIL PROTECTED]> Sent: Saturday, September 27, 2003 2:58 PM Subject: Re: workflow - Re: integration with other app > Matthias: > >I've been dinking with this workflow extension for awhile, amidst other > madness, and here's what I've come to observe.

Re: BeanMapping WAS: [Poll] action mappings
Yes, it answers my question. I use the BeanUtils.copyProperties() to move data back and forth between my transfer objects and my dynaforms and I don't like doing that because (a) it seems an unnecessary step since I'm already marshalling data into & out of resultsets (b) I have to maintain the object field/member variable information in yet another place (UML, database schema, xml schema, struts-config (& possibly HTML should be on this list too)) (c) BeanUtils won't convert strings based on locale-specific information (yet, AFAIK though it might be in the pipeline) re (b), when I only have to specify that in one place, I know that I will have died and gone to programmer heaven :) On 09/27/2003 05:00 PM Sgarlata Matt wrote: Hmm well I do sometimes use different types in my DynaForms, but I think I want to move away from this practice in the future. There was a fairly good discussion of this in the post "[repost] Special view information -> ActionForm or request?" starting on 9/18. To answer your real question about using DynaForms as transfer objects, I only use them if I am transferring data from the presentation tier down to the business tier. I use the DynaBean interface to do this. It's pretty slick how this works. If for some reason I decide not to use DynaActionForm at some point in the future you can make a POJO into a DynaBean by just passing "new WrapDynaBean(pojo)". If you want your business tier to have things already nicely placed in the correct type you could always use ConvertUtils to populate a strongly-typed POJO from your ActionForm. Or if you want to use a typed DynaBean I think you can declare your own DynaClass or something, but I'm not really sure on all the specifics of this process. Does that answer your question?

I like to try and use the supplied interfaces (i.e. DynaBean) if they suit my needs and, to date, DynaBean has served me well. You can use BeanUtils to map DynaBeans to POJO's and visa versa (as a matter of fact you can to it to/from maps also I believe). After working with DynaBeans some more, I agree with you. I am going to use them as my type for transfer objects as well instead of the strategy I outlined before where I defined my own IInputForm and IDynaInputForm interfaces. My only gripe with using the commons-beanutils would be that I would perhaps like to have a couple levels of DynaBean and perhaps at the simplest level only have an interface like you describe (i.e. fewer methods in implement). I would like to see an empty interface called org.apache.commons.beanutils.Bean, but I can see that being a huge point of contention so I'm not going to press for it.

Re: workflow - Re: integration with other app
Matthias: I've been dinking with this workflow extension for awhile, amidst other madness, and here's what I've come to observe. Please let me know if my observations are correct, and if there's not a "better/easier" way to achieve my goals: I have a logical process flow for achieving the task of entering new data. This requires 7 different screens on input information, as each subsequent entry page requires info from the prior. I originally defined this as one primary "workflow". Everything flows from one page to the next, so long as I don't use the browser back button and change prior information. If I do this (hit browser back, change a form field, submit), the next page ends up blank; granted, I haven't added any "back button" links to the page. This is obviously due to a workflow violation exception being thrown. That's fine.However, in order for the workflow engine to redirect the user to the proper page, it appears i'm going to have to break down my one workflow into 7 individual "workflows", each leading to eachother using primary and secondary flows, and then adding in a global foward for a violation for each one of those new 7 segments. Is this correct? It seems like a lot of work for a simple process, and I'm afraid I'm missing something. Also, back to the browser back button. In running the demo, I can see that hitting the browser back from wizard page 2 will continually redirect me back to wizard page 2. yet, in my application, hitting the back button just takes me to the prior screen. Is this a result of not having the violation logic in place? If so, why isn't there a blank screen like I described above?

I'm rigid thinking that no web page really _requires_ JavaScript, not at
least because some clients using my application will not allow active
scripting in their browser. Sites like e. g. www.hp.com (view with
disabled JS) make me feel confirmed.
Isn't it possible to iterate the request parameters if there's one that
has ".x" and ".y" suffix? Since no one really wants to submit values
with a name like this I suggest the struts framework automatically
generates a parameter so the handling in the action is consistent as for
a submit button. Of course there has to be some tag defining the name of
the "action" parameter.
Wouldn't that be nice?
This method work for me:
String getActionParameter(Map p_Keys)
{
String l_Key;
Iterator l_iKeys = p_Keys.keySet().iterator();
while (l_iKeys.hasNext())
{
l_Key = (String)l_iKeys.next();
if( l_Key.endsWith(".x")
&& p_Keys.containsKey(l_Key.substring(0, l_Key.length()-1)
+ "y"))
{
return l_Key;
}
}
return null;
}
To be used in the execute method of the action:
String l_Action = getActionParameter(p_Request.getParameterMap());

Re: Accessing action error problem
You can use the attached JSPs to display all the attributes in the request.
Just look for the attribute that stores the errors. In general when I was
starting with Struts I found the attached JSPs very helpful because you can
see the types of information Struts stores for you and where it is stored.
Also, if you look at the Globals class the locations for many of these
attributes are recorded there. I just find it easier to look at the actual
attributes in the request using the attached JSPs rather than hunting
through the javadoc of the Globals class.

Re: BeanMapping WAS: [Poll] action mappings
Hmm well I do sometimes use different types in my DynaForms, but I think I want to move away from this practice in the future. There was a fairly good discussion of this in the post "[repost] Special view information -> ActionForm or request?" starting on 9/18. To answer your real question about using DynaForms as transfer objects, I only use them if I am transferring data from the presentation tier down to the business tier. I use the DynaBean interface to do this. It's pretty slick how this works. If for some reason I decide not to use DynaActionForm at some point in the future you can make a POJO into a DynaBean by just passing "new WrapDynaBean(pojo)". If you want your business tier to have things already nicely placed in the correct type you could always use ConvertUtils to populate a strongly-typed POJO from your ActionForm. Or if you want to use a typed DynaBean I think you can declare your own DynaClass or something, but I'm not really sure on all the specifics of this process. Does that answer your question?

Re: BeanMapping WAS: [Poll] action mappings
Hey Matt, do you use different types in your dynaforms or do you stick to just strings? I was wondering about using dynaforms as transfer objects like you mention, but I only use strings, since incorrect form entries for non-string types don't make it back into the form after validation failure. And I would want to have types in my transfer objects.

You can use BeanUtils to map DynaBeans to POJO's and visa versa (as a matter of fact you can to it to/from maps also I believe). After working with DynaBeans some more, I agree with you. I am going to use them as my type for transfer objects as well instead of the strategy I outlined before where I defined my own IInputForm and IDynaInputForm interfaces. My only gripe with using the commons-beanutils would be that I would perhaps like to have a couple levels of DynaBean and perhaps at the simplest level only have an interface like you describe (i.e. fewer methods in implement). I would like to see an empty interface called org.apache.commons.beanutils.Bean, but I can see that being a huge point of contention so I'm not going to press for it.

Hi Denis, sounds like a bizarre request to make - what is the difference between the two authentication mechanisms that can't be reprogrammed on the other site? I assume you are not using container-managed authentication otherwise it wouldn't be a problem.

Re: Going from https on /member.do, back to http on index.jsp?
An elegant solution by Amazon is to require a login everytime the user switches into SSL - even if they are logged in already. Session hijacking still worries me though because the app I am building at the moment is quite data intensive, and the customers of the website who will use it to enter and store their data will obviously hold it in high value. It worries me that some discontented session-hijacker could easily destroy the data belonging to someone else. The problem is that the average surfer would probably consider it weird that the whole site runs under SSL. Currently only sites such as PayPal do that. How much that could affect sales is something I will have to consider. Adam On 09/27/2003 03:38 AM Craig R. McClanahan wrote: Jayaraman Dorai wrote: -Original Message- From: Craig R.

Max Cooper wrote: Creating an index.do is one option. If it is not marked as secure, sslext will write an absolute URL back to http:// for it. Many Struts users advocate that all requests should be served by Actions, even if the action merely forwards to a JSP. I actually have a more important concern about doing this -- exposing information to people who can listen in on the packets that go back and forth. Many people would like, for example, to have the login form be secure so that your password is not sent across the wire encrypted, but then go back to http for the rest of the session for the better performance. The seemingly ideal solution is to have the destination of the login submit require SSL, and then switch back. Using a security constraint, you can even let the container worry about the http->https transition for you. Or, you can use things like SSLext that is nicely integrated into Struts. However, the servlet spec offers no help in switching back to http, because it is not a recommended practice. Why? Consider the fact that you now trust subsequent transactions from the same user, and are typically using the session that was established earlier (whether the session was originally created in http or https turns out not to matter). But the session id is no longer encrypted (it's either in a cookie or in rewritten URLs), so it can be easily forged by anyone with a network snooper between you and the server. How do you guarantee that an after-login request on that session is not being sent by someone who is forging the session id because they snooped it? I'm a conservative on security issues -- if I have an app that needs SSL sometimes, I arrange things to never accept a non-SSL request on the same session again, once I've switched to SSL (easy to do with a Filter, for example). If you're concerned enough to protect the password, you should be concerned enough to pay the CPU overhead for SSL the remainder of the session. Otherwise, it's likely that encrypting the login form will just give you a false sense of security. I think you can also use the secure attribute in the sslext tags to indicate whether the target of the link or form should be accessed securely. In this case, you would add secure="false" to the sslext:link tag that goes back to /index.jsp. -Max Craig Will it be useful for cases like where credit card information are sent through SSL and hence are secured. They might snoop the session, if it is switched back to http, but still the credit card information is not. Similarly, snooper might steal the sessionId, but the password is not stolen and is secured. Is that not better than nothing? Am I missing something? The credit card information is not going back and forth across the wire unencrypted, but your session identifier is (for servlet based apps, it's normally in a cookie or encoded into the URLs). In at least some ecommerce apps I'm familiar with, the credit card number *is* stored in an HttpSession (or something analogous for non-servlet technologies), so that the customer can go back and buy some more stuff, and do an expedited checkout the second time. If I know that your app works that way, I can snoop the wire until the user goes to https (which I can't read, but can see happening) and then back to http (which I can see). Now, I've got the cleartext version of the session id, assume that the user has gone through the checkout, and can submit false additional purchase transactions to your app based on that session id, without having to resubmit a credit card number. Protecting just the password, but not the remainder of the current session, is *not* better than nothing -- IMHO it is substantially worse because it gives you a *false* sense of security.

Re: [Question] Image path - Best way?
Struts has a tag that will put the context path on the front of the src URL for you. Here's an example: If you want to reserve the option to internationalize what image gets displayed, Struts has good support for that, too. For instance, if you have a button image with some text on it, and you want to be able to show different images for different languages, you can put the image path in the ApplicationResources.properties file and use something like this: You can also use the altKey attribute of the tag to internationalize the ALT, um, thingy. In your base ApplicationResources.properties file, you might have something like this: button.clickMe.src=/images/button_clickMe.jpg button.clickMe.alt=Click Me You can override these values for other languages in locale-specific versions of the ApplicationResources.properties file. One thing to be careful of with specifying images this way is that if you set the size in the tag (which is a good idea to speed rendering performance in the browser), make sure that all the images for a given button match the size that is specified. They don't exist now, but it might be useful if heightKey and widthKey attributes were added to the tag to allow those to be looked up in the properties file as well. That way you could specify different sizes for the images if they happen to be different for different locales.

Re: change dynamically ApplicationResources path
You may use following to set bundleName defined in struts-config.xml... request.setAttribute(Globals.MESSAGES_KEY, bundleName); but bundleName is MessageResources object . and bundleName is key attribute of message-resources in struts-config.xml... OR If above do not meet your requirements... than you have write factory of message-resources and overload loadLocale method of PropertyMessageResources...

Re: ActionErrors and Servlet Filters
you may use following
request.setAttribute(Globals.ERROR_KEY, errors);
to set global parameter of errors..
set action error as usual...

Re: Including 4 's into 1 page with includes?
Make sure you do request.setAttribute
("FormName",dynaActionFormObjectInstance); for each of the forms you have
manually populated. Because, what you don't see struts do in the
background is that everyform you receive in your actions the form is
automatically added to the request object. Because you are populating
these forms yourself you must add them to the request object manually in
order for your tags to be able to see them.
