SV: What is the best way to pass a parameter to a forward? Create a utility class

SV: Struts Workflow - Questions ?
Hi I am not sure if I understand your question right, but the way I understand it is. You have some action that either can forward to itself (looping) 3 times ( 4 time it should be a workflow violation) or in case everything is ok forward to another action ? Well you have a couple of options. You could have a action mapping like this action path=/somePossibleLoopingAction type=dk.somePackage.someAction name=someForm scope=session set-property property=primaryWorkflow value=MyWorkflow / set-property property=prevState value=loginfailure / set-property property=prevState value=someOtherState / set-property property=newState value=loginfailure / set-property property=nextState value=loginfailure / set-property property=nextState value=loginsuccess / forward name=success path=/nextAction / forward name=failureLogin path=/somePossibleLoopingAction / forward name=violateAction path=/someActionThatViolates / /action In your somePossibleLoopingAction you could have a session variable that holds the count of unsuccessful logins, after the third it could foward to /someActionThatViolates, this action should of course have some states that would be violated and then the workflow engine would trigger a workflow violation where your session forms would be cleaned and you could eventually make sure that the user is banned or whatever you want. This should happen in your workflow violation action class. Just make sure you have a global forward like this ! forward name=workflowViolation_MyWorkflow path=/handleWorkflowLoginViolation.do / And then of course the action mapping represented by the /handleWorkflowLoginViolation.do. action path=/handleWorkflowLoginViolation type=dk.somePackage.SomeAction set-property property=primaryWorkflow value=MyWorkflow / set-property property=endWorkflow value=true /- makes sure that this workflow is ended forward name=noNextStateViolation path=/somePathOfYourChoice / /action In case you are in the looping phase, take a look at the workflow mapping. As you can see we have a prevState and a newState and even a nextState that are the same. This means this action accepts that the previous action is itself, and that the next action can be itself, that's the way I implemented it. Hope this helps, if you have more questions feel free to ask!

Hi, I'm trying to resolve a problem I have by making use of Struts Workflow - Using this as I need something that will prevent jump-out within the process The login process of my app has a number of conditions which dictate which page I send the user to next. I understand the basic's of the Struts Workflow but am a little confused when we get to the looping/forwarding aspects Basically the section of the flow is as follows: SecurityFilterAuthentication - Is User Authenticated ? If Y - StartWorkflow - Retrieve User Settings - Is 3fromN login required ? If Y - Do 3FromN Else -Record Successful Login - ...Continue Workflow The 3FromN section has to allow the user 3 attempts and then do a Lock Out Action or if successful continue to the Record Successful Login Action How do I make those decisions within the workflow ?

SV: How to create an include which calls an action: jsp:include page=some action Really need help : The Answer!
What I did is the following. I have a master jsp and in this jsp I inserted the following page. tile:insert controllerUrl=/viewNavigation.do page=/jsp/myJspPage.jsp/ Now there are two important things to consider. First in your action mapping definition in this case viewNavigation.do you must add the redirect=true to the foward attribute. If you do this, your navigation action does not need to return null, if you don't add this attribute, then your action must return null. The problem with the latter, is that you can't call this action (viewNavigation.do) in any other way than using the tile tag, because it will jus be a blank page. Here is my action mapping! action path=/viewNavigation scope=session name=someForm type=something.web.controller..ViewMultiNavigationAction forward name=success path=/jsp/myJspPage.jsp redirect=true / /action On my jsp page it looks like this Jsp start *** Bla bla Bla bla tile:insert controllerUrl=/viewNavigation.do page=/jsp/myJspPage.jsp/ Bla bla Bla bla Jsp end My action does not return null because of the redirect=true forward name=success path=/jsp/myJspPage.jsp redirect=true / Hope this helps Cheers Tommy -Oprindelig meddelelse- Fra: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sendt: 25. februar 2004 21:31 Til: Tommy Holm - TELMORE Emne: SV: How to create an include which calls an action I'm getting the following error.

Hi everyone. I have already asked this once but didn't get any answer, I have tried everything that I could think of but no luck, so if any of you have an idea what to do, I would really be happy for any help. I have a problem, I have a jsp page which should include the result of an action call. The action should prepare the bean associated with the action and render which then in the end should be included in the master jsp.(The include is a menu, which the action should prepare). The problem is that after the include, the rest of the JSP page is not rendered. It does somehow make sense but is there anyway around this or a common strategy to achieve this.

Logic:iterateTag
Hi. I have created a html td tr tag which can used neted inside the struts iterate tag. The idea is that the tag will generate the surrounding TR and TD tags, so that the data exposed from the iterate tag can be properly displayed in several columns for each row. Now the problem is that my tag requires to know the size of the collection which the iterate tag is iterating over. What I have done in the doStartTag is this: IterateTag parent = (IterateTag)findAncestorWithClass(this, IterateTag.class); if (parent == null) { throw new JspTagException(This tag must run inside + org.apache.struts.taglib.logic.IterateTag); } else{ Collection temp = (Collection)parent.getCollection(); if(temp != null){ logger.debug(YEAH parent collection was not null and size is + temp.size()); logger.debug(Lets check the ofset ); String offset = parent.getOffset(); if(offset != null){ logger.debug(Ofset is not null + value is + offset); logger.debug(So the actual size should be + (temp.size()- Integer.parseInt(offset))); } } else logger.debug(Collection from parent tag was null); No matter what the collection from the struts iterate tag is alway null, which means it's a non initialized collection. What am I doing wrong ? How do I gain acces to the size of the collection that the iterate tag is iteration over ? Any help is greatly appreciated.

State change before form validation
I am currently using the struts workflow extension and I have stumbled upon some strange behaviour. When you on a jsp page with form and submit that form, the workflow state changes before the validation result is taken into consideration. Please correct me if I am wrong. This puzzles me because the idea of struts form beans are that if validation fails, you are being returned to the same page you originated from. That gives a problem because you then need to have a previous state for your action that is the same as the newState, otherwise you get a violation. Maybe I remember wrong but I seem to remember seing an answer (from Matthias who is one of the developers of the workflow extension) on the struts mailinglist that it's not a good idea to have a previous state that is the same as the newState, didn't understand why, so could anybody perhaps give a few comments on the state being set before form validation Cheers and regards Tommy Holm, System Udvikler TELMORE A/S Carl Gustavsgade 3, 2630 Taastrup Telefon 70218700, Mobil 22582344 www.telmore.dk - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
