Using Struts with XSLT

[Jan Arendtsz]

I would like to use Struts as my MVC framework but use XSLT for
rendering the final HTML/WML pages.  I thought that this would be
somewhat of a common approach but was surprised to find very little
information when searching through these archives.  Is this something
that Struts 1.1 will support?

The application that I'm hoping to building should eventually support
several UI devices as well as multiple languages and that's the reason
we would like to use XSLT.  However, we are also somewhat concerned
about some of the performance ramifications when using XSLT.

It seems that using Struts 1.0, I would have to do the following:
- Use the action object to call JavaBeans or EJBs to retrieve data from
the database either as XML text, Row sets (JDBC 2.0 extension), or
custom data objects (the optimal way would be not to use XML since it's
not as efficient), and store this data as a request attribute.  Once the
action object has forwarded to the corresponding view JSP or Servlet,
this data can be retrieved (since it has a request scope), converted to
a DOM object and transformed using a XSL stylesheet.  I was also hoping
to use the stylesheet template caching described in the book "Java and
XSLT" by Eric Burke
(http://oreilly.com/catalog/javaxslt/chapter/ch05.html) to improve
performance.  The JSP page used for the view will not contain any Struts
tags and therefore can be a servlet.

Variations to this could include the following:
- Using the Jakarta XSL tag lib within the JSP page to do the
transformation.  This could mean that I won't get some of the
performance benefits using stylesheet caching.
- Use filters (new to servlet 2.3 spec).  Don't know much about this,
especially on the performance side.

For those of you have worked on a similar application, do you have any
suggestions or best practices?  I'm trying to use both Struts (purely as
the Model 2) and XSLT together and this does not seem to be a common
practice.  I could drop one or the other if the solution is a good one.


Does anyone have thoughts or experience with other frameworks such as
Coccon, Turbine, and Barracuda?

Thanks
Jan

Re: ActionForward to url outside of the web app

[Ted Husted]

Isn't the "session" a creature of Java? Can you share it with non-Java
code?

>From your direction structure it appears that script1 and page1 are not
part of the same application root. (Unless the reference is suppose to
be path="/N/jspFiles/page1.jsp".) If that were the case, then you could
not share the session, even if both were written in Java. 

You might be able to share information with cookies, the old-fashioned
way.

ActionForward to url outside of the web app

[Fu, Walter]

Normally, when forwarding to a new page, one can use the  tag in
struts-config.xml to help the Action's perform() method to indicate what the
next page to go to. Typically, the next page is a url within the same web
application (sharing the same web.xml).

I have a situation where I want to mix some legacy (web app) system L with a
new web application N. I want L and N to share to same session information.
The legacy web app L is not even java-based.

Example directory structure: 
  /L/serverSideScripts/script1
  /N/jspFiles/page1.jsp

I can reference page1.jsp using: 
I wanted to reference script1 doing something like: 
Of course, this does not work.

Any pointer as to what I can do so as to integrate the new system with the
old? Keep in mind that I want both L and N to share the same session.

Thanks,

Walter

Re: exceptions

[Ted Husted]

Once an exception gets up to the ActionServlet, it's either going to a
white screen, or the default error page (if it is a ServletException, or
wrapped therein). 

I would recommend that you catch any exception you can handle in the
Action, where you have a chance to handle the error and branch the
control flow. That's the Action's job: handle (routine) errors and
exceptions, and control the flow.

I would say if the Action invokes the business object, and it can throw
LDAP exception, then the Action should catch those, and do whatever is
needed to recover.

[Todd Fulton]

Design wise . . . do you all tend to propagate exceptions all the way up to
the ActionServlet -- centralized like -- or rather grab them in a more
granular fashion?

For instance, I've got Action classes using a business object layer which
has LDAP exceptions possible down deep.  This layer is essentially separate
and distinct from the web-struts layer.

Do I send them through, or deal with them at some juncture in-between?

Re: Capturing an outgoing response.

[Adam]

Another way is to proxy it yourself.  This may or may not work if you 
are dependent on user state.  Basically, you server code plays the role 
of the web browser ala wget.  

 (not sure if the following code is correct.  Let the buyer beware)

URL url = new URL(pageToCache);

String pageToCacheContent = (string)url.getContent();

If you are dependant on user state, You may need to do some additional 
hacking

RE: Form Bean

[Prengaman.Karen]

Cameron, are you still experiencing this problem?  I just ran into the same
thing and thought I would share how I solved it.  

I too was creating a form bean and then adding it to the session.  When the
corresponding jsp was loaded, all the values were reset to the default.
Upon examining my struts-config.xml, I noticed the following in my action
mapping for that jsp:

Note: irrelevant attributes have been omitted



Notice the value of the scope attribute...  I decided to add my newly
created form bean as a request attribute instead of to the session, and my
problem was solved.  To confirm my suspicions, I changed the value of the
scope attribute to session and then saved my form bean in the session, and
it still worked.

Hope this helps.

RE: Silverstream, struts and UTF-8 Encoding

[Krueger, Jeff]

Russell,

This comes from the SilverStream admin guide on page 90.  It tells
you how to change it in the httpd.props file, but you might be able to get
it to work via the web.xml.


_
Specifying character set encoding


The SilverStream server uses the following server property when URL-encoding
and -decoding form content:

http-server.com.sssw.srv.international.UrlEncoding

NOTE SilverStream stores the encoding and other server startup properties in
the httpd.props configuration file, which is located in the
SilverStreamInstallDir\resources directory. For more information, see
Appendix A, "The httpd.props File". By default, the SilverStream server uses
utf-8 (Universal Character Set Transfer Format) for URL encoding and
decoding. Because utf-8 can encode ASCII characters without requiring
modification, utf-8 works well for English and most western languages.
Because languages
using multibyte encodings are not a subset of utf-8, character encoding and
decoding will not work properly with them.

When to change the encoding scheme You typically need to change the encoding
scheme only when the majority of client browsers in your environment use
character encodings that are not ISO 8859-1 (Latin 1). For example, a
Japanese Web site that serves content to its employees using the ShiftJIS
encoding may want to change its SilverStream server's encoding property to
SJIS.

To change the encoding scheme:

1. To change from the default utf-8 to another encoding, add the following
line to the httpd.props file (located in the resources directory beneath the
SilverStream root directory):

http-server.com.sssw.srv.international.UrlEncoding= NewEncoding

2. Enter the language mapping needed at your site in place of the
NewEncoding variable.
Check the Sun Web site if you are unsure about the Java string mapping for
your
language.

3. Restart the SilverStream server.

URL content will be encoded using the new encoding scheme after you restart
the server.

Subject: Silverstream, struts and UTF-8 Encoding


I am having some problems with a struts based application in that the
browser does not seem to change to UTF-8 encoding and as a result, i am
losing some characters. I have read quite a few postings regarding i18n
including this excerpt:

1) Specify the content type for the JSP output:

<%@ page contentType="text/html; charset=utf-8" %>

You can also do this by setting the content type header manually, using
response.setContentType().

2) Specify the content type to the browser:



3) Specify the default content type to the container. In our case, we are
using Resin, and so do this:




I have changed the jsp for the first 2 but the browser still doesn't
recognise that it is meant to be UTF-8. Has anyone any experience of this
or know how to resolve it? I have been unable to do the last step in the
web xml as i dont know what the context-param name would be for
silverstream - does anyone know?
I think the web.xml should look something like:



weblogic.httpd.inputCharset./*
UTF-8

...


but with a different param-name.

Any clues as to why UTF-8 isn't working would be appreciated.

help: config filter-mapping and struts

[c tang]

Hi all,

I wrote an app using struts and it works fine.  Now I
want to add a filter, so that a pre-defined page will
be filtered before return.  The question is how to
specify .  I tried lots of options, it
does not work.

For the following action,

 
  
 

I want to compress the response when it is forward to
success page(/success).  When I map filter to
generateBig.do, the doFilter method is invoked, but
the request page is returned.  Even if correct page is
return, I think mapping to generateBig.do is not the
right way because failure page will be filter too. 
When I map filter to /success(or the servlet mapping
to /success), the doFilter method is not even invoked.


please help!

If you have three submit buttons for the same form only the submit

so you could check for the existence of the parameter to find out what

Re: Problem with multilingual submit button with request parameters

[Mark Gordon]

If you have three submit buttons for the same form only the submit 
button that is pressed will be sent as a parameter... i think.

so you could check for the existence of the parameter to find out what 
button was pressed.  The parameter name will not be localized just the 
value... and who cares what the value is because you only care if it exists.

RE: Problem with multilingual submit button with request parameters

The problem is actually with HTML itself.  The value attribute of a submit
button specifies both the button label as well as the value submitted to the
server.

Subject: Problem with multilingual submit button with request parameters


Hello struts experts,

I can't get a submit button to work which uses a  for a
localized button text _and_ a request parameter at the same time. I have
browsed the mail archive, but haven't found a solution for this. Maybe one
of you can tell me the way to achieve my goal:

A form on my page contains several submit buttons, which trigger different
actions (like 'Create', 'Search' and 'Cancel'). To circumvent the problem of
a single action target in a form I did add a request parameter to each
submit button (as suggested earlier in this mailing list):

  
Search
  

Because my application has to support different languages (like English and
German), I also use the  tag to set the button text according
the Locale setting in the session:

  

  

Each of the above code samples works well, like it's described in the
documentation and as I expected it.

But if I try to combine both techniques to get a multilingual submit button
with a request parameter, like in:

  

  

it does not work: Instead of my desired result - a button with a (german)
label 'Suchen', which submits a request parameter 'action=search' - I do get
a button labeled 'search' (with a lowercase 's'). The 'value' attribute
seems to be used used twice _with a different meaning_.

The Struts  taglib guide says under 'Common Form Tag Attributes':

"value : Value of the label to be used with this element. This value will
also be submitted as the value of the specified request parameter."

As far as I understand this sentence, it says that the 'value' attribute is
used twice for different purposes: For the label of the button and for the
request parameter value.

Have I done something wrong or misunderstood something? Or is this a slight
design flaw in the i18n support (using the same attribute twice)? Does
someone know a solution or workaround for this problem?

I think all paths are relative to the root of your application.

I am new to struts... so I may be all wrong but


make the path in your action "/jsp/logon"


  
  



then in your form use "/jsp/logon" as the action

Hi Ashoka,

your sample struts config file does not define a form bean. Maybe this is
the reason for your problem.

You should add something like

(before to the action definition).

Hope this helps

Re: How to use Data source in *.jsp

The datasource is an attribute in application scope.  You can use the 
pageContext to get this attribute.

You may be able to do something with a  tag or a 
 tag to expose this attribute... but I could not figure 
it out.

by the way you aren't going to put a business rule in a jsp page 
are you  :-)

I try to keep all my sql in a bean then call methods to enforce business 
rules or pull data to be displayed in a page.

Scriptlets bad, taglibs good :-)

Hello,

I am relatively new to Struts and am encountering a problem with the
struts-config.xml file.  I have set up a global-forwards like below:



Then I set up an action like below:




Then I wrote the following index.jsp page:

<%@ page language="java" %>
<%@ taglib uri="/tags/struts-logic" prefix="logic" %>


Now when I hit index.jsp, I receive a blank page from Tomcat 4.0.  If I
review the Tomcat logs, I see that it encountered a 404, but why?  I
thought
it should have found the action "/Menu" and forward it to the menu.jsp.

Hi Ted,

I joined the Struts Mailing List yesterday and have already learned some
valuable information.  I have seen Tiles refered to in several different
posts and am wondering where I can find out more information about it (I
couldn't find a Contrib folder, but wasn't sure where to look for it).  If
you or someone else could point me in the right direction, I would
appreciate it.

Thanks,

Karen

The Tiles version (in the Contrib folder) can be integrated with the
Action forwards, eliminating places where another physical file might
otherwise be needed. This uses a XML configuration file, which is very
"Struts-like".

CSS can be used along with JSP templates.

Other than that, I would say a CUI is a CUI, and you could compare each
on its own merits.

What other interface rendering utilities did you have in mind?

You can have your JSPs in the WEB-INF directory - I use that and it works
fine.

Are you using a  in your JSP?

Hello,

I am relatively new to Struts and am encountering a problem with the
struts-config.xml file.  I have set up a global-forwards like below:



Then I set up an action like below:




Then I wrote the following index.jsp page:

<%@ page language="java" %>
<%@ taglib uri="/tags/struts-logic" prefix="logic" %>


Now when I hit index.jsp, I receive a blank page from Tomcat 4.0.  If I
review the Tomcat logs, I see that it encountered a 404, but why?  I
thought
it should have found the action "/Menu" and forward it to the menu.jsp.

I am sure this is something simple, but I can't seem to see what wrong with
the above.  This is running under Struts 1.0 and Tomcat 4.0.

Any assistance is greatly appreciated.

Barry,

This can happen if your data source is improperly configured. The Action
mappings aren't processed due to an error while trying to access the
datasource. My most frequent cause has been a misconfigured JDBC URL, or

Silverstream, struts and UTF-8 Encoding

[rmcsporran]

I am having some problems with a struts based application in that the
browser does not seem to change to UTF-8 encoding and as a result, i am
losing some characters. I have read quite a few postings regarding i18n
including this excerpt:

1) Specify the content type for the JSP output:

<%@ page contentType="text/html; charset=utf-8" %>

You can also do this by setting the content type header manually, using
response.setContentType().

2) Specify the content type to the browser:



3) Specify the default content type to the container. In our case, we are
using Resin, and so do this:




I have changed the jsp for the first 2 but the browser still doesn't
recognise that it is meant to be UTF-8. Has anyone any experience of this
or know how to resolve it? I have been unable to do the last step in the
web xml as i dont know what the context-param name would be for
silverstream - does anyone know?
I think the web.xml should look something like:



weblogic.httpd.inputCharset./*
UTF-8

...


but with a different param-name.

Any clues as to why UTF-8 isn't working would be appreciated.

RE: Exception: Cannot retrieve mapping for action

[tnist]

Thank you, I realize that the *.do will work, I had it that way initially.
However, I was reviewing the "Artimus" example by Ted Husted and liked how
he had the URL mapping setup and the struts-conf.xml file so I thought I
would give it a try.  But so far, it has not worked at all in my
application, but works just fine in the example and I can not see where the
difference is at.

Again, thanks for the reply.

Re: action forward tag...

[John Nikolai]

Thanks for your reply Sandeep,

We are already using struts templates to render the pages. So we have 
something like the following:

template.jsp
 - Contains all navigation
 - Gets the content page

content.jsp
 - Inserts into template.jsp
 - Puts several items (title, image, etc...) into template.jsp

So, as you pointed out, we display the page with the following URL:
  http://localhost/dynamic/content.jsp

The problem is when the content contains a struts form element and the form 
is successfully submited. We need the "success" page to render at the same 
navigation level. So when an ActionFroward object is returned from the 
process() method, we want the url to look like this, again:

  http://localhost/dynamic/content.jsp

BUT, instead of seeing the form, we want to only see a "success" message. 
This is required due to the way our dynamic navigation works.

Does it make sense to have another taglib added to the struts html taglib? It 
would be very similar to the  tag but it would show a 
successfull message instead -- . So this would add another 
couple of classes to struts: ActionSuccess and ActionSuccesses to be 
consistent with the ActionError classes. Perhapes there can be some logic 
tags used as well to remove the form elements so that we only display the 
successfully submited message without the form.

Or this all may be possible with the existing classes and taglibs. 
Any other thoughts or suggestions?

Thanks again for your help,
  - John

The Tiles version (in the Contrib folder) can be integrated with the
Action forwards, eliminating places where another physical file might
otherwise be needed. This uses a XML configuration file, which is very
"Struts-like".

CSS can be used along with JSP templates. 

Other than that, I would say a CUI is a CUI, and you could compare each

Hello,

I am relatively new to Struts and am encountering a problem with the
struts-config.xml file.  I have set up a global-forwards like below:



Then I set up an action like below:




Then I wrote the following index.jsp page:

<%@ page language="java" %>
<%@ taglib uri="/tags/struts-logic" prefix="logic" %>


Now when I hit index.jsp, I receive a blank page from Tomcat 4.0.  If I
review the Tomcat logs, I see that it encountered a 404, but why?  I
thought
it should have found the action "/Menu" and forward it to the menu.jsp.

I am sure this is something simple, but I can't seem to see what wrong with
the above.  This is running under Struts 1.0 and Tomcat 4.0.

Any assistance is greatly appreciated.

Re: Newbie: Iterate tag : Object properties not updated to form bean from JSP

[dhay]

Rajoy,

Please read the archives of this list before posting questions.  This problem
has been addressed many times.

To summarise again, to update in an iteration, the names of the form elements
must have the index included eg. name="parameter[0].value".  Struts will then
use this to make the following call to populate the form bean:
FormBean.getParameter(0).setValue(value).  In order for this to work, you must
have a Parameter getParameter(int index) getter in your form bean, and
appropriate get/setters in your parameter object.  Various previous messages
provide more details, and there is an example I posted at
http://www.mail-archive.com/struts-user@jakarta.apache.org/msg12084.html.

Cheers,

Dave

Hi again ..
I am quite new to struts  .. hope someone will take time to go through my
query which I am reposting  ( if not I am gonna come back with a more catchy
subject line !! ;-) )

Thankx in advance (again)
Rajoy

HI all
I've encountered a situation as follows

1. I have a 'UserInfoContainer'  form bean which contains a Vector of
individual 'UserInfo' objects.
2. Each UserInfo object is iterated through using the 'iterate' tag in the
JSP.
3. Some 'UserInfo'  data (say 'NickName' ) is displayed in a text box so
that the user can modify it.

Every thing is going fine till now. The trouble is once I submit the form
and retrieve the 'NickName' from each UserInfo object in the
UserInfoContainer object passed to the perform method , it doesn't reflect
the modifications user entered in the text box. Basicaly the data entered by
the user isn't set back to each UserInfo object by the Action servlet.

I've read in the struts docs that the iterate tag copies each object in the
collection ( in my case the userinfo veactor) to a page scope bean
referenced by the value of 'index' attribute. So I guess the values in the
text boxes inside the iterate tag never gets set to the original objects in
the FormBean.

A. Is my understanding correct ?
B. Am I doing somethimng wrong here ?
C. Is there any way to tackle this problem?

I am at present using lots of request.getParameter methods to get the values
edited by the user. But it really does increaase dependency between the JSP
pages and  the action classes. SO I wonder whether that is the correct way
to go even ...

FYI : 'UserInfoContainer' is a session scope formbean.
Thankx in advance
Rajoy

Re: Common User Interface for JSP's

[Ted Husted]

The Tiles version (in the Contrib folder) can be integrated with the
Action forwards, eliminating places where another physical file might
otherwise be needed. This uses a XML configuration file, which is very
"Struts-like".

CSS can be used along with JSP templates. 

Other than that, I would say a CUI is a CUI, and you could compare each
on its own merits.

What other interface rendering utilities did you have in mind?

Where are they ?

RE: Setter method doesn't work with indexed tag

[dhay]

Hi again,

Took another look at your code - wondering why there are no setter/getters in
your Parameter.java?!!  Did I miss something?

You obviously need these for the set to work.  You still haven't posted your jsp
page to show what you are doing there, but if you have something like this:

  

 

this will be translated by struts into a call
ParametersForm.getParameter(0).setValue(value).  So for *each* parameter
attribute you use on the page, you must have an appropriate getter/setter.

Cheers,

Dave

I use log4j for debugging purposes. My PO number and

for the po details (a vector of param) which turned
out null even though there are values retrieved from
the database. I've been debugging this for about 2
days. I'm currently using request.getParameter() as a
temporary workaround.

Subject: Newbe - problem with Struts-Config.xml


Hello,

I am relatively new to Struts and am encountering a problem with the
struts-config.xml file.  I have set up a global-forwards like below:



Then I set up an action like below:




Then I wrote the following index.jsp page:

<%@ page language="java" %>
<%@ taglib uri="/tags/struts-logic" prefix="logic" %>


Now when I hit index.jsp, I receive a blank page from Tomcat 4.0.  If I
review the Tomcat logs, I see that it encountered a 404, but why?  I thought
it should have found the action "/Menu" and forward it to the menu.jsp.

I am sure this is something simple, but I can't seem to see what wrong with
the above.  This is running under Struts 1.0 and Tomcat 4.0.

Any assistance is greatly appreciated.

Regards,

When you call a page for the first time and you want some values in

just initialise the form bean with the values you want to preselect.

Re: Newbie: Iterate tag : Object properties not updated to form bean from JSP

[Rajoy]

Hi again ..
I am quite new to struts  .. hope someone will take time to go through my
query which I am reposting  ( if not I am gonna come back with a more catchy
subject line !! ;-) )

Thankx in advance (again)
Rajoy

HI all
I've encountered a situation as follows

1. I have a 'UserInfoContainer'  form bean which contains a Vector of
individual 'UserInfo' objects.
2. Each UserInfo object is iterated through using the 'iterate' tag in the
JSP.
3. Some 'UserInfo'  data (say 'NickName' ) is displayed in a text box so
that the user can modify it.

Every thing is going fine till now. The trouble is once I submit the form
and retrieve the 'NickName' from each UserInfo object in the
UserInfoContainer object passed to the perform method , it doesn't reflect
the modifications user entered in the text box. Basicaly the data entered by
the user isn't set back to each UserInfo object by the Action servlet.

I've read in the struts docs that the iterate tag copies each object in the
collection ( in my case the userinfo veactor) to a page scope bean
referenced by the value of 'index' attribute. So I guess the values in the
text boxes inside the iterate tag never gets set to the original objects in
the FormBean.

A. Is my understanding correct ?
B. Am I doing somethimng wrong here ?
C. Is there any way to tackle this problem?

I am at present using lots of request.getParameter methods to get the values
edited by the user. But it really does increaase dependency between the JSP
pages and  the action classes. SO I wonder whether that is the correct way
to go even ...

FYI : 'UserInfoContainer' is a session scope formbean.
Thankx in advance
Rajoy

RE: Force login...

[Sobkowski, Andrej]

Hello All,

by using a JSP tag to check if the user is logged, aren't you mixing somehow
logic and presentation? In theory, you should provide a way that is
independent of the fact that you store your user in the session (though
Struts does it that way). Furthermore, you may need to not only check if the
user is logged, but also if he/she has specific permissions/roles...

My suggestion would be similar to Peter's:
- subclass the Action class with your own with a checkLogon() method that
throws an exception if the user is not logged (the extension would be
defining a checkAuthorization(auth))
- at the beginning at the main command method of each _Action_ that requires
the user to be logged id, do something like

  public ActionForward perform(...) {
try {
  checkLogon();

// Add here business logic if user is logged in
...

} catch (UserNotLoggedException e) {
// React to user not logged (or not authorized)
// Probably forward to login page...
}   
  }

What do you think?

Andrej

To do it properly you have to:

(1) Write a abstract base class, say `SecureActionBase' that provide
security methods
"checkLogon()". Write a default implementation of `checkLogin' that
subclasser can
override. If no user is not longer return an action mapping forward that
redirects
to the "login". Otherwise let the user continue.

(2) Borrow the `CheckLoginTag' from the Struts example and use it as it is,
or modify it.
You put the checklogin tag at the beginning of your JSPs.

(3) Extend the Struts ActionServlet with a custom class for your project
that will enable you
to look for instances of `SecureActionBase' and then call the security
methods.
Like so:

   protected ActionForward processActionPerform(Action action,
 ActionMapping mapping,
 ActionForm formInstance,
 HttpServletRequest request,
 HttpServletResponse
response)
throws IOException, ServletException
{
 

if ( action instanceof SecureBaseAction ) {
SecureBaseAction baseAction = (SecureBaseAction)action;
 ...

if ( baseAction.isSecureAction() ) { // This action needs
security
 
ActionForward fwd = baseAction.checkUserSecurityAccess(
context, mapping, request );
if ( fwd != null ) {
// Redirect to login screen or other warning page
return fwd;
}
 // Otherwise we are authenticated, continue
}
 ... // pre-process checking U desire

ActionForward forward = action.perform(mapping, formInstance,
request, response);

 ... // post -process checking U desire
return forward;
}

Re: Digester content with elements

[Bob Byron]

The examples that I have seen only show "neat" cases
where there is no intermixing of text and content..
Case 1: I want to remember this date,, forever!

I want to see an example of how to parse the following:
Case 2: I want to remember this date,, forever!

In Case 1, the text is all neatly contained in tags.
In Case 2 however, the text mixes with the subtags.  The documentation
did not show this kind of example.

Re: Force login...

[Martin Samm]

a common method is to insert a custom tag on each page and 
a) checks the session, say, for a suitable attribute and value
b) presents a login / redirects to login if no such value is found

RE: Force login...

[Princeton Lau]

Scott,

Check out the Struts sample app, it has two features that could solve your
problem.  

Firstly, it has a login form and action.  The sample app checks against an
XML file for a list of users, but you could code the action to access a
business object that verifies the username and password.  If the lookup
fails, then return them to the login page with an error.

It also has a custom tag, checklogin , to ensure that the user has logged
in before doing anything.  Just place this tag in your JSPs and if the user
isn't logged in yet, it will return them to the login page.

HTH,

Princeton

RE: struts-example.war

I'd suggest using Tomcat 4.0.  I've installed the struts-example.war on it
without any problems at all - and no setup.

I was wondering how to digest content that contains additional
elements.

For example, I have two tags "text" and "date".  I want to parse
the following:
I want to remember this date, , forever!

Ultimately I want to end up with three objects as follows 
(I hope you get what I am inferring below):
MyText("I want to remember this date, ");
MyDate();
MyText(", forever!");

Granted, it would be easy enough to do:
I want to remember this date, , forever!
But, I prefer to do the first way.

Thank You,

Force login...

[Scott Watson]

My appologies for asking something that has probablly been asked and answered before, 
however, I wasn't able to find the answer in
my searches.

How do you force someone to login before being allowed to access your application.  It 
doesn't seem right to code this in each
action class.

Is it possible to search the archives for this list like the SERVLET and the JSP lists?

Thanks

Newbe - problem with Struts-Config.xml

[tnist]

Hello,

I am relatively new to Struts and am encountering a problem with the
struts-config.xml file.  I have set up a global-forwards like below:



Then I set up an action like below:




Then I wrote the following index.jsp page:

<%@ page language="java" %>
<%@ taglib uri="/tags/struts-logic" prefix="logic" %>


Now when I hit index.jsp, I receive a blank page from Tomcat 4.0.  If I
review the Tomcat logs, I see that it encountered a 404, but why?  I thought
it should have found the action "/Menu" and forward it to the menu.jsp.

I am sure this is something simple, but I can't seem to see what wrong with
the above.  This is running under Struts 1.0 and Tomcat 4.0.

Any assistance is greatly appreciated.

Todd G. Nist

ClassCastException when moving extended Action and ActionForm classes in the classpath

[Leonardo Mena]

Hi folks! I am from Uruguay, South America, so sorry my English :)

I am evaluating the Struts framework as an MVC aproach in the web tier in
our company product (after attending the entusiastic presentation in the
JavaOne conference!). The framework convince us pretty much, but we are very
concerned with a situation that we hope is due to our little experience with
Struts.


PROBLEM:

If we move our extended Action or ActionForm classes from WEB-INF/classes to
somewhere else in the servlet container classpath (we're using ServletExec
3.0c), an error occurs (ClassCastException) wich prevents the application to
continue.


DETAIL:

I don't want to include further details (such as servlet logs) unless you
think it's necesary, but tell you that the error takes the form of a
java.lang.ClassCastException in the ActionServlet, when it attemps to cast a
new extended Action class (instantiated via reflection) to its superclass
Action. We're pretty confussed because the class is found and instantiated
when moved, but generates a cast error, even when the log tell us that its
superclass is the one Struts is casting to: org.apache.struts.action.Action.
The same occurs with ActionForm. The web browser shows a processed error
message: "The following error occurred: 500 - No action instance for path
/logon could be created".

Any help will be very appreciated, we hope we're doing some trivial mistake
or something else and this is not a limitation on the framework. We think
that from a JVM standpoint this make no sense, but...

Thanks in advance,
Leonardo Mena

If you are not using framesets - I would suggest

Re: ActionForms extending ActionForms

[Ted Husted]

The problem is that html:form is looking for the ActionForm associated
with its ActionMapping. 

Having one Action handle more than one ActionForm isn't a problem. But
getting html:form to handle more than ActionForm is problematic. 

If the *properties* for each registration type are the same, then you
may not need two different ActionForm beans at all. 

The Action just needs a way to tell the registeration types apart,
perhaps by using a hidden property. 

This is admittedly not a very OOP approach, but HTTP is not a OO
protocol, so we have to make allowances on this tier ;-)

Interally, you might want to have different beans for the different user
types; these should not be ActionForm beans, but some other bean
representing your internal model, and not bound to HTTP.

You should also omit the "scope" property from the html:form, since, in
this case, it will get all that out of the Struts config.

Hi all,

On the "http://jakarta.apache.org/struts/struts-logic.html"; site page, two
very interresting tags are presented : 'empty' and 'notEmpty'.

I have downloaded struts v1.0, but I just can't find them neither the
declaration in the "struts-logic.tld" file, nor the corresponding .class
files in "struts.jar".

Where are they ?

I absolutely need them ;-)

ActionForms extending ActionForms

[Richard Dallaway]

I've been wondering about the best way to go about using struts in this 
situation

I have two types of forms (for different kind of web registrations) which 
are very similar, but not quite identical.  The associated 
RegistrationAction will perform slightly different tasks depending on which 
form it is given.  So I could go for two actions, one for each of the 
forms.  That'll work.

But I was wondering if instead I could do have a base RegistrationForm 
(containing lots of common stuff), and then extend it to give me say 
UserRegistrationForm and StaffRegistrationForm.  A single action would 
accept a form of type "RegistrationForm" and do whatever it needed to 
do.  (For the sake of argument, assume that the JSP form can be shared, so 
validation is OK).

So I tried this, by having a startRegistrationAction that created an 
instance of either StaffRegistrationForm or UserRegistrationForm , casting 
it to be of type RegistrationForm, and put it in session scope under the 
name "registrationForm" before forwarding on to the JSP form for the end 
user to complete.

When the form is submitted to the RegistrationAction I get a null form 
passed.   The config I have is




 
 
 

The form tag looks like:
   

and of course if I change the form-bean type to be 
"StaffRegistrationForm" or "UserRegistrationForm" it will work for one of 
those specific instances.

Am I right in thinking that because my form is of type (say) 
StaffRegistraionForm (which happens to extend RegistrationForm), struts 
won't be able to find a RegistrationForm type object in the session? Which 
is why my Action sees a null form.

So my questions are really
(1) is this a sane thing to be trying?
(2) is there a way to do this?

Many thanks
Richard

Re: Capturing an outgoing response.

[Sandeep Takhar]

I believe there is also a tag that struts uses that
can take the output servlet/jsp and place it in a
bean.  If you look at the code for this tag you will
see how they get the output of a servlet and place it
in a bean.  This should work for any type of output. 
Unfortunately I don't have the code with me -- or
which tag it is, but I remember it as being an xml/xsl
tag that could be used to reference a url and placing
the output of that url to a bean.  The idea being that
this bean could then be used as a starting point for
an xsl transform.

Incompatible object error trying to instantiate an Action

[Rob Breeds]

Hello I've been successfully forwarding a form submit to an Action (A0)
which uses a parameter in the form to forward to another Action (call it
A1) which performs business logic and populates a bean to display in a
result page. It all works.

I now copy that working Action (A1) class to another business logic Action
(A2) and rename it where appropriate.

I set up the config file for the new Action A2, and change my input form so
it offers another parameter such that Action A0 will forward to A2.

When the new Action class (A2 is FindBusinessSimple in this case) is
forwarded to, I get this weird error in the log:

[Servlet LOG]: action: Error creating Action instance for path
'/findBusiness', class name '**.inquire.FindBusinessSimple':
java.lang.VerifyError: (class: /inquire/FindBusinessSimple, method:
perform signature:
(Lorg/apache/struts/action/ActionMapping;Lorg/apache/struts/action/ActionForm;Ljavax/servlet/http/HttpServletRequest;Ljavax/servlet/http/HttpServletResponse;)Lorg/apache/struts/action/ActionForward;)

Incompatible object

If I select the other parameter in the form, class A1 still works as
before.

(I've had to * some of the package names for confidentiality reasons
but that doesn't change the problem!)

Any ideas please? I'm stumped. I'm running in WebSphere App Server 4.0 and
up until now, that hasn't been a problem...

Thanks

Producing an XML document from a form

[Matt Raible]

I'd like to be able to produce an XML document from my form that wraps the
bean's values with the method names.  Has anyone done this, or should I do it
on my own and submit the "extension?"

Thanks,

Matt

Re: Setting bean property with custom tag

[Ted Husted]

If you want to set a value that is part of an ActionForm, you can use
. 

Note that the Struts html:form tag will automatically create a bean if
it is not already in the expected scope. An Action will also create a
ActionForm bean if it is missing. Otherwise, you need to create it
yourself.

Also note that the Struts bean tags are not coupled to the ActionForm
names in the Struts config. They obtain the type through introspection,
not by looking things up in Struts config, and work equally well with
any bean.

Re: Check Box,Radio button (Urgent)

[Ted Husted]

It's hard to say without seeing your code. They should automatically
select the current value.

RE: struts-example.war

[Andrew Kirkland]

Indeed I did. The only thing I dont have is the:

 JDBC 2.0 Optional Package Classes - Struts supports an optional
implementation of javax.sql.DataSource, so it requires the API classes to be
compiled. They can be downloaded from
http://java.sun.com/products/jdbc/download.html.

I want sure if these were compulsory, but i downloaded the class files, i
just dont know where to put them, but i dont think this is the problem.

Hi Andy,

First of all, don't break your head on the desk, use a pillow! Now, to your
problem:
Did you instal all the prerequisite software, how it is described on
http://jakarta.apache.org/struts/installation-1.0.html?

Marcel

After a week of banging my head on my desk I am still no closer to getting
any struts example to work.
I am using tomcat verdsion 3.3-m3 and i have unpacked the struts-example
file.nI have tried it on 2 macheines with the same result. I displays the
first Jsp but the image on it is missing as it has been given a stupid url
(sturtspower.gif;jsessionid=837983). When i try to submit any form in the
example, my browser is redirected to logon.jsp;jsessionid=454333 or whatever
number. If i click on registration i am redirected to
.../struts-example/editRegistration.do;jsessionid=nfrwce4s01?action=Create.
I realise i have brought this up before but i thought i should re-itterate
the problem before asking any questions.

Does anyone know of any prerequisite software i might be missing in order
for this to be happening? It happens with any strusts application i try.

Thanks for your time

Andy
