Subject: Re: Checkbox Arrays
I don't know if this is the right thread. But I just got multibox working
in my app (including preservation of checkbox entries between forwards).
Let me share with you what I have to see if this helps:
in Jsp: (cleanSolutionAreaTypes in an Application-scoped Vector)
tr
td align=left
Solutions Area*
/td
td align=left
logic:iterate id=solutionAreaType name=cleanSolutionAreaTypes
html:multibox property=solutionAreaTypes
bean:write name=solutionAreaType property=id/
/html:multibox
bean:write name=solutionAreaType property=name/br
/logic:iterate
/td
/tr
in Form:
protected String[] solutionAreaTypes = new String[0];
public String[] getSolutionAreaTypes()
{
return solutionAreaTypes;
}
public void setSolutionAreaTypes(String[] solutionAreaTypes)
{
this.solutionAreaTypes = solutionAreaTypes;
}
What was causing me some exceptions was this. I originally used another
application-scoped vector called solutionAreaTypes for other purposes
(like drop-down lists). That Vector contains an entry that has a null ID
value (eg. name = --specify-- value=). This was causing Struts to throw
a non-intuitive exception. I then created another Vector without this entry
in it and everything seems to work fine now. Of course I've only gotten it
to work about 15 minutes ago so I'll let you know later if it really works
;-)

Try pulling the bean value out into a script variable.
Taglibs cannot be nested within another taglib as an attribute.

Im not sure how the ActionForm changes things, but without an
actionform
your
could do this
Each checkbox can have the same name, but a different value.
When the form is submitted, the checkboxes that have been checked are
in
the
request.
You can use the request.getParameterValues(checkBoxName) to retrieve
a
string
array of the values for the checked boxes.

RE: Quick Iterate Question - DefaultTableModel
I've just tried using a DefaultTableModel and succeeded nesting the iterate

JSP is as follows:

tr
struts_logic:iterate id=element name=rows
tdstruts_bean:write name=element//td

Here's a quick one - anyone use or modify iterate to support iterations
through a DefaultTableModel. Since it's just a vector of vectors we tried
nesting iterate tags, but to no avail. Anyone already done this or do I need
to code it myself if I want it (hehe)? :)

Problem with tag
Hi, I'm new to struts and I have a little problem with the tag library : In an iterate tag body, I want to write a link to an anchor of the page. I wrote this code : logic:iterate id=faq name=faqList type=be.dummy.faq.bean.FAQBean/ p html:link page=/listFAQ.do anchor=bean:write name=faq property=id/ bean:write name=faq property=question/ /html:link /p /logic:iterate But I have this error : org.apache.jasper.compiler.ParseException: C:\jakarta-tomcat-3.2\webapps\dummy\listfaq.jsp(16,60) Attribute faq has no value If I write this : logic:iterate id=faq name=faqList type=be.actel.faq.bean.FAQBean/ p html:link page=/listFAQ.do anchor=1 bean:write name=faq property=question/ /html:link /p /logic:iterate It's working : p a href=http://localhost:8080/dummy/listFAQ.do#1;Is this working ?/a /p So how must I do to make it work ? I don't understand the error ... Thanks Laurent CORNELIS PS : Sorry for my very bad english ...

I posted this same response to your Posting Collections question yesterday.
Here it is again. If you use the html:multibox, you can get back an array
of
key values instead of an array of booleans. They key values can be Longs,
Strings, whatever, as long as it uniquely identifies the row that you want
to know was checked. If you haven't used multibox, it generates an html
checkbox. The array that will be set in your form will only contain the key
values for the rows that were checked.
Here is the post from yesterday:
I think I am doing the same thing that you want to do using the
html:multibox. When the form is submitted you get an array of the ids that
are checked and then you can go delete them.
in the jsp form (where restaurant id is a key for the item being deleted):
logic:iterate id=restaurant name=favoriterestaurants
...
html:multibox property=favoriteRestaurantRemoveList
bean:write property=restaurantId name=restaurant/
/html:multibox
...
/logic:iterate
in the form class:
private Long favoriteRestaurantRemoveList[] = new Long[0];
public Long[] getFavoriteRestaurantRemoveList() {
return (this.favoriteRestaurantRemoveList);
}
public void setFavoriteRestaurantRemoveList(Long
favoriteRestaurantRemoveList[]) {
this.favoriteRestaurantRemoveList = favoriteRestaurantRemoveList;
}
I am not sure if initializing the array to new Long[0] is necessary,
probably not.

Don't use the html:checkbox, use html:multibox and use bean:write in the
body of the tag. An html:multibox resolves to an HTML checkbox.

RE: Posting Collections
Thanks Niall. I'm currently frustrated because I'm finding it hard to discover all the information I require. Seems to be a general lack of documentation on struts usage, but it's a learning curve like anything else. I like Struts in principle, and what it is trying to achieve, I just wondered if you considered it ready for building a large-scale project. For example, this change that you have submitted is going to affect a lot of code. So my options are to stick to my current solution without changing any of the Struts code, or modify the code so that it does what I want in the hope that the change will get propagated through to the next release. It doesn't feel like a good way to be working, but I take your point about Open Source, and I partly agree. For the time being I'm going to persevere - and I look forward to seeing your custom tags so I don't have to hack around with the code every time a new version comes out. Cheers ;-) Tony From: Niall Pemberton [EMAIL PROTECTED] Reply-To: [EMAIL PROTECTED] To: [EMAIL PROTECTED] Subject: RE: Posting Collections Date: Thu, 10 May 2001 20:23:31 +0100 This issue applies to all form field tags, not just checkboxes. Modifying struts tags is currently a pain, but I just subimitted a bugzilla enhancement to re-factor the tags so that they are more granualar and make it easier to override descrete bits such as generating the name attribute. In principle the enhacement has been accepted and I hope to submit a patch in the next few days. If it is accepted I will have a set of custom versions of these tags for this behviour very soon and you won't have to start hacking around with the code every time a new version comes out and anyone will be welcome to them. Addtionally this issue is all on the ToDo list for 1.1 and I'm sure it will be sorted then. I think struts is excellent, and I love open source because you can always look inside to see what they've done. Of course it doesn't do everything yet ;-) but I can't see it getting anything but better. We have done quite a bit of work customizing the ActionServlet and the way its been built is excellent, making it really easy to add addtional behaviour (hopefully) without having to hack around every time a new version comes out. Niall -Original Message- From: Tony Karas [mailto:[EMAIL PROTECTED]] Sent: 10 May 2001 10:34 To: [EMAIL PROTECTED] Subject: RE: Posting Collections Many thanks Niall, that clears things up for me. Do you know if there is a reason why this is the behaviour for checkboxes? Is this just with checkboxes or other tags as well? I don't really like the idea of modifying the struts code - the whole point of deciding to use it is for code reuse - I don't want to start hacking around with the code every time a new version comes out. Do you have an opinion on using Struts? I've been using it for a couple of weeks now and have been struggling because of basic lack of information. I get most of my training from this news group! I'm wondering whether I should just jack it in and use something else. Cheers Tony From: Niall Pemberton [EMAIL PROTECTED] Reply-To: [EMAIL PROTECTED] To: [EMAIL PROTECTED] Subject: RE: Posting Collections Date: Wed, 9 May 2001 20:51:00 +0100 The problem is the CheckBox tag currently sets the HTML name attribute to the property, so your JSP will produced something like this: input type=checkbox name=delete So all the checkbox fields will have the same name. In order for Struts to populate your Retailer bean with the delete values you need the generated HTML to look like this: input type=checkbox name=retailer[0].delete input type=checkbox name=retailer[1].delete etc etc. Struts would then use getRetailer(0).setDelete(boolean) to set the delete attributes correctly. Unfortunately there is no easy solution - many people resort to scriptlets to generate the name properly and there are quite a few messages in the archive about this. I created my own versions of Struts tags and changed them to generate the name correctly - I like that much better - no java in the view.

Passing request to a common action class from multiple forms
Hi, I have a common Action class,which will receive request from multiple forms. This action class will then forward request to a common jsp and on selection of a value from this jsp,the value has to be set in the input form(which called the common action class). Then,request has to be forwarded to the input form. How to do this ? Mani
RE: nanduri can u help ??ApplicationResources.properties
Hello Amit, In your web.xml file, when you declare the ActionServlet there is a place where you specify the fully qualified path to the ApplicationResource.properties file. Check that out. servlet servlet-nameaction/servlet-name servlet-classorg.apache.struts.action.ActionServlet/servlet-class init-param param-nameapplication/param-name param-valuecom.agilquest.onboard.ApplicationResources/param-value /init-param .. Note : if your ApplicationResource.properties file is not in a package then make sure that you put it under the classes directory. If you are using a war file for deployment make sure that you follow the proper directory structure for creating a war file. Any more questions give a shout.

proliferation of action classes?
I'd like to validate a development approach. One of our developers is essentially creating two action classes for each .jsp page / form. The second post action class always forwards to another action. Here's an example from a test struts-config.xml. !-- Get SF -- actionpath=/getsf type=com.mslv.webapp.sftester.action.GetSfAction name=sfForm scope=request forward name=successpath=/sftest.jsp/ /action !-- Post SF -- actionpath=/postsf type=com.mslv.webapp.sftester.action.GetSfAction2 name=sfForm scope=request forward name=successpath=/process.do/ /action !-- Display SF -- actionpath=/process type=com.mslv.webapp.sftester.action.GetSfAction3 name=sfForm3 scope=request forward name=successpath=/sftest2.jsp/ /action And here's a scenario where I don't like the functionality with struts. Suppose: o /getsf /postsf both use sfForm. o /process uses sfForm3. o sfForm and sfForm3 both have a custAcctID field o /sftest.jsp /sftest2.jsp have html:text property=custAcctID/ o /getsf sets the custAcctID = 100 o /postsf sets the custAcctID = 200 Then o when sftest2.jsp displays, the value of custAcctID is still 100. I realize this is normal... the values get copied from the request to the form. One workaround is to examine the forward, instantiate sfForm3, update custAcctID, and make sfForm3 an attribute of the request. Then when sftest2.jsp displays, it has the correct updated value for custAcctID. BUT - this is a lot of extra work. Questions: 1) Are there any other known issues or limitations of using an action to forward to another action? 2) Could this always be accomplished with fewer, larger action classes? (an equivalent pattern) 3) Any other comments? Have a nice weekend. Thanks. Wayne [EMAIL PROTECTED]
Re: Passing request to a common action class from multiple forms
I have a domain.jsp which has a button on click of which action is forwarded to an action class which displays cascade.jsp. In cascade.jsp the objects displayed are same even though their values may be different.User can select some values and these values have to be passed back to input.jsp. The reason for the common action class is because,the functionality is same for all forms which have to call cascade.jsp.The variables to be selected from cascade.jsp (oid and name) is always same,even though their values may be different. How to get input from different forms and pass it back to the callee form. If it sounds spaghetti is there a better way of implementing it. Mani Nanduri, Amarnath wrote: Can yo be more detailed ?

Constants.TOKEN_KEY value proposed change (doesn't work with javascript!!)
Hi,
I use the token_key for transaction support.
But the value of the TOKEN_KEY = org.apache.struts.taglib.html.TOKEN
This is a very odd value to have as a hidden input field on your form.
Which is generated by the FormTag:
input type=hidden name=org.apache.struts.taglib.html.TOKEN
value=
Because you want to use that hidden field in some javascript:
function submitNextpage(themakey)
{
document.nextpage.org.apache.struts.taglib.html.TOKEN.value=themakey;
document.nextpage.submit();
}
You get a javascript error!
Because javascript sees all names between points as an object.

RE: Error handling with taglibs
You need to hack in...and do some dirty work on each jsp page... You need to write your own html:error tag . Whenever there are some errors to be shown, you simply use some javascript to send focus to the first error field. Also in your jsp page (for evey text field) you might want to do something like an if,else condition.. If no error show plain, else show in red font with the error msg.

Re: Error handling with taglibs
I would suggest requesting a change to the current struts implementation. I think this has been thought about because there is the facility to include the property that has caused the error. I would also like to do something like this. I suppose there would be at least two ways of going about it: 1) Make the ActionErrors component more accessible in the jsp page - so that some kind of logic tag could be used to generate either a normal html:text tag or an html:text error tag, or 2) Add an error attribute to the html:text tag (and others) that would render the text box differently if an error is associated with it. These are my thoughts.

How can I use set-property property=foo value=123 / in struts-config.xml ? I want to use it in place of forward to store Action configuration info (set-property is specified in the dtd). Tried to add getter setter to Action descendant - but assignment by introspection didn't seem to work. Looked at the source for ActionServlet, and the digester class does appear to be doing something with this property, although it looks like it is only looking for a single instance in an action.

RE: possibility of default action?
As I understand the current struts-config.xml, no. You can associate any number of forms to the same action, but I don't think that's what you're asking. That is to say, you can design a default action for forms, but you still have to add each form to struts-config.xml even if they use the same action. It'd be a nice feature, though it may break away slightly from Model II.

struts and tomcat4 reload causes exception
Hi, It sounds like this topic's been pretty exhaustively covered on the mailing list, but I haven't yet seen a solution to it, so sorry for dragging it up again. I'm pretty sure I've read every message on the list on this topic... I'm having seriously difficulty getting my webapp, which is based on struts to reload after I make changes to the source. I initially started encountering errors with Tomcat 3.3, when I recompiled any of my classes the next request would generate an exception. It would continue to generate exceptions until I completely restarted tomcat. At least it seemed that Tomcat was properly detecting the changes though... Now I'm running the just-released Tomcat 4 Beta 4, and the 11 May (today's) build of Struts and I have exactly the same problem: A Servlet Exception Has Occurred java.lang.ClassCastException: org.apache.struts.action.ActionMappings (see below for full stacktrace). (I've also tried Tomcat 4 Beta 1 with Struts 1 Beta 1). I'm pretty new to JSP and struts myself, but I am fairly sure that Struts itself is having problems reloading. The errors are always from struts classes. My app works perfectly until I change a class or 'force' a reload using Tomcat 4's manager feature. Calling the reload feature of struts makes no difference either. I'm fairly sure it's not my code, because I installed the struts-example app, and if I force a reload of that app (using tomcat manager again), I get the same kind of errors. The index.jsp page crashes it with this message: javax.servlet.ServletException: Cannot find message resources under key org.apache.struts.action.MESSAGE Surely the example app must work properly? Perhaps I've just messed up the configuration? Any tips that can help me would me most grateful (as well as saving my hair...)

Re: filtering unwanted characters
In the callback that deals with characters you could add a reference to a method that seeks the specific character you are trying to filter. This is just an idea, and may not be the best solution, but is is one possible approach. I actually made my own filter which works on a character by character basis.

My apologies if i have offended anyone. I am looking for some open source code that deals with filtering technology. Basically i want to filter any unwanted characters from the user input data. The user might try to pass in some SQL quesries or try to run some shell scripts or put special characters which might be rejected by a database (or even corrupt it). If no such open source code is available then i want to write something like that. I was wondering if anyone has done some thing like this in the past and if so, can they share their experiences ? Also is there any place i can search for some 'searching algorithms' which i plan to use as the backbone of my filters that i plan to implement.

Subject: RE: Checkbox Arrays
I posted this same response to your Posting Collections question yesterday.
Here it is again. If you use the html:multibox, you can get back an array of
key values instead of an array of booleans. They key values can be Longs,
Strings, whatever, as long as it uniquely identifies the row that you want
to know was checked. If you haven't used multibox, it generates an html
checkbox. The array that will be set in your form will only contain the key
values for the rows that were checked.
Here is the post from yesterday:
I think I am doing the same thing that you want to do using the
html:multibox. When the form is submitted you get an array of the ids that
are checked and then you can go delete them.
in the jsp form (where restaurant id is a key for the item being deleted):
logic:iterate id=restaurant name=favoriterestaurants
...
html:multibox property=favoriteRestaurantRemoveList
bean:write property=restaurantId name=restaurant/
/html:multibox
...
/logic:iterate
in the form class:
private Long favoriteRestaurantRemoveList[] = new Long[0];
public Long[] getFavoriteRestaurantRemoveList() {
return (this.favoriteRestaurantRemoveList);
}
public void setFavoriteRestaurantRemoveList(Long
favoriteRestaurantRemoveList[]) {
this.favoriteRestaurantRemoveList = favoriteRestaurantRemoveList;
}
I am not sure if initializing the array to new Long[0] is necessary,
probably not.

I have an array of checkboxes in my ActionForm represented by

and I have a setter function
public void setDelete( boolean[] values )

delete = values;

The problem is that I have only checkboxes that are checked
get sent back -

1. Therefore,
it is not possible for me to determine which checkbox has

In the documentation it tells me to use reset() in ActionForm

Determining odd-even table rows
I'm trying to figure out how to do a green-bar effect (different backround colors for every other row of a table) with struts/jsp. I am using a tagified javax.sql.Rowset. I can iterate through the rowset via my tags (reworked jakarta DBTags). The problem, more of a mental block, is how do I alternate the backround colors of the html rows I am writing WITHOUT resorting to scriptlets. I have just added a tag to get the current row, so I have that returing, but what do I do with it? The logic tags in struts deal only with comparisons to constants. I need to do some math to determine whether the current row is odd/even so I can set the backround. Is it easier than this and I'm missing it? My goal here is not to do any scriplets. I'm putting together a set of tags to help our web guy build pages using only tags. Thanks for any help, Bill Pfeiffer
RE: struts and tomcat4 reload causes exception
Keep your precious hair. I'm pretty sure Struts and Tomcat are operating as designed. I noticed this when I first started working with Struts too, and it caused me about thirty minutes of horrible pain and suffering until I realized that restarting the server is required due to the nature of the framework. To me, it seems reasonable to restart Tomcat every time a class gets recompiled. I try to make sure my code is pretty solid before testing moving on to testing. I admit, after being a scripter for a few years (perl, later php), I felt a little restricted by this. But like any compiled language and even when scripting, it's best to avoid the code-compile-test-repeat routine if you can because ... it is bad. When you say that you installed the struts-example, did you deploy the .war like the manual suggests, or did you extract it manually?

Accessing ServletContext from session object
I was wondering if anyone else has tried to access the ServletContext from the session object. I have written a class that implements HttpSessionBindingListener so I can detect when a users session expires. When the session expires, the valueUnbound method is called and is passed an event. From that event I can retrieve the users session object and this is where the problem begins. The only object I have is the users session object, but I need to somehow get an attribute from the ServletContext to mark that the user session has expired. Has anyone on the list done this before?

RE: Checkbox Arrays - Internationalising them?!
Do you want bean:message to be able to get the key from a bean method? It
doesn't do that now...
Since bean:write is printing the value of a bean property, your bean
property could use the MessageResources class to do the internationalization
in your bean method.
Inside an action you can get the MessageResource object and the Locale
object by calling these methods from the base Action class:
Locale locale = getLocale(request);
MessageResources messages = getResources();
messages.getMessage(locale,some.key,args));
where args is an optional String array.
I am not sure how easy it would be for you to pass the messages and locale
objects into your bean and use them there.

RE: How can I use set-property property=foo value=123 / in struts-config.xml
You must extend the ActionMapping class to include the property you are
wanting to set. Inside your action, just cast the ActionMapping object to
your custom mapping object. Inside the deployment descriptor (web.xml), set
the init-param mapping to point to your custom mapping object.
--- start struts-config.xml ---
action ...
set-property property=myProperty value=123/
..
/action
--- end struts-config.xml ---
--- start web.xml ---

How can I use set-property property=foo value=123 / in
struts-config.xml ?
I want to use it in place of forward to store Action configuration info
(set-property is
specified in the dtd).
Tried to add getter setter to Action descendant - but assignment by
introspection
didn't seem to work.
Looked at the source for ActionServlet, and the digester class does appear
to be doing something
with this property, although it looks like it is only looking for a single
instance in an action.
As far as I can tell, either it is not intended for general use or it is
broken.
Any thoughts?

Re: still fighting HTTP HTTPS problem
I'm using a standalone container, and I find that everything works
transparently (only one session) if I resort to hard coding the scheme.
Right now, I'm doing this in the Struts-config.
forward name=standard
path=http://data.wxxi.org/wxxi-gavel/register/logon.jsp/
forward name=secure
path=https://data.wxxi.org/wxxi-gavel/register/logon.jsp/
which are called with code like this in the action
String url = null;
if (secureMode) {
url = mapping.findForward(secure).getPath();
ActionForward actionForward = new ActionForward(url,true);
return (actionForward);
}
else return (mapping.findForward(standard));
where I'm tracking secureMode as a session attribute.
If they login or register in secure mode, I end the process with a [[
BIG LINK ]] that routes them back to the http scheme.
Messy, but it gets me through the day.
I haven't had time to think about it, but it seems to me that we should
be able to work this into the custom tags. Struts is very good about
automagically converting the links when you switch schemes, so it seems
to me we should be able to force the tags to one scheme or the other,
when appropriate.

RE: How can I use set-property property=foo value=123 / in struts-config.xml
I think you got the wrong end of the stick. The action elements in struts-config relate to ActionMapping classes, not the Action class. You need to sub-class the ActionMapping class and add your properties and getters/setters to that class. Then you need to add a init-param element for the ActionSrvlet to the web.xml to tell it to use your custom ActionMapping class as follows: init-param param-namemapping/param-name param-valuecom.myPackage.myActionMapping/param-value /init-param Then in your action class you need to cast the mapping object to your custom class and then call the getter to retrieve the property values.

RE: struts and tomcat4 reload causes exception
Well, if that's the way it's designed, I guess I can live with it too, but it does seem a bit restrictive. From the messages I've read on Tomcat 4, it seems a LOT of effort has gone into making it reload classes when they're changed, so I don't really see the point of it, if we're going to resign to restarting the server anyway. What's the point of the 'reload' function of the Tomcat 'manager'? It doesn't do what (it seems to me) it should do, which is restart the app, just as if the server had been started afresh. To answer your question, I just copied the WAR file into tomcat/webapps and let it be deployed automatically. Does that make a difference? Cheers, Simon. At 12:23 PM 5/11/01 -0700, Anthony Martin wrote: Keep your precious hair. I'm pretty sure Struts and Tomcat are operating as designed. I noticed this when I first started working with Struts too, and it caused me about thirty minutes of horrible pain and suffering until I realized that restarting the server is required due to the nature of the framework. To me, it seems reasonable to restart Tomcat every time a class gets recompiled. I try to make sure my code is pretty solid before testing moving on to testing. I admit, after being a scripter for a few years (perl, later php), I felt a little restricted by this. But like any compiled language and even when scripting, it's best to avoid the code-compile-test-repeat routine if you can because ... it is bad. When you say that you installed the struts-example, did you deploy the .war like the manual suggests, or did you extract it manually?

Re: still fighting HTTP HTTPS problem
Ted,
You can collapse your code down to this:
return mapping.findForward(secureMode ? secure : standard);
by adding redirect=true to your secure forward definition in struts-config.

The user might try to pass in some SQL quesries or try to run some shell scripts or put special characters which might be rejected by a database (or even corrupt it). If no such open source code is available then i want to write something like that. I was wondering if anyone has done some cheers, -Ian -- Ian Kallen [EMAIL PROTECTED] | AIM: iankallen
RE: Determining odd-even table rows
I have a RowTag that does this, it generates tr elements and you can specify either oddColor/evenColor attributes to generate bgcolor= attributes or oddStyle/evenStyle parameters to generate class= attributes for CSS. So the jsp looks like this: table logic:iterate id=.. name=.. property=.. util:row oddColor=#C0C0C0 evenColor=#FF td./td td./td /util:row /logic:iterate /table You can either specify both odd and even or just one of them. I'll send it if you're interested. Niall -Original Message- From: Bill Pfeiffer [mailto:[EMAIL PROTECTED]] Sent: 11 May 2001 20:08 To: Struts-User Subject: Determining odd-even table rows I'm trying to figure out how to do a green-bar effect (different backround colors for every other row of a table) with struts/jsp. I am using a tagified javax.sql.Rowset. I can iterate through the rowset via my tags (reworked jakarta DBTags). The problem, more of a mental block, is how do I alternate the backround colors of the html rows I am writing WITHOUT resorting to scriptlets. I have just added a tag to get the current row, so I have that returing, but what do I do with it? The logic tags in struts deal only with comparisons to constants. I need to do some math to determine whether the current row is odd/even so I can set the backround. Is it easier than this and I'm missing it? My goal here is not to do any scriplets. I'm putting together a set of tags to help our web guy build pages using only tags. Thanks for any help, Bill Pfeiffer
Re: still fighting HTTP HTTPS problem
Are you saying that an http request can be forwarded to an https
request? That doesn't make sense; if the browser doesn't have an https
session setup, the server can do whatever it wants to resolve the request
translation. You have to redirect to go from an http request to an https
request.

I'm using a standalone container, and I find that everything works
transparently (only one session) if I resort to hard coding the scheme.
Right now, I'm doing this in the Struts-config.
forward name=standard
path=http://data.wxxi.org/wxxi-gavel/register/logon.jsp/
forward name=secure
path=https://data.wxxi.org/wxxi-gavel/register/logon.jsp/
which are called with code like this in the action
String url = null;
if (secureMode) {
url = mapping.findForward(secure).getPath();
ActionForward actionForward = new ActionForward(url,true);
return (actionForward);
}
else return (mapping.findForward(standard));
where I'm tracking secureMode as a session attribute.
If they login or register in secure mode, I end the process with a [[
BIG LINK ]] that routes them back to the http scheme.
Messy, but it gets me through the day.
I haven't had time to think about it, but it seems to me that we should
be able to work this into the custom tags. Struts is very good about
automagically converting the links when you switch schemes, so it seems
to me we should be able to force the tags to one scheme or the other,
when appropriate.

hello everyone...
i still couldn´t find a solution on how to switch from
let´s say http://localhost:myport/myapp/something.jsp to
https://localhost:mysecureport/myapp/somethingelsethatneedstobesecure_oreven
thesamepage.jsp
while retaining resp. cloning the content of my sessioncontext...
i am using the urlrewriting-method to manage my sessions
as far as my experience tells me i get two different sessionIDs for
http://localhost:myport/myapp/something.jsp
and the corresponding
https://localhost:mysecureport/myapp/something.jsp
how can i copy the sessioncontext to the secure side and vice versa?

Re: still fighting HTTP HTTPS problem
ActionForward actionForward = new ActionForward(url,true); The forward here is a bit of a misnomer. Using true forces a redirect.
