RE: Using JSTL to access form bean properties

[Paul McCulloch]

Rather than remember the name of the form bean, I use the following:



Note that I uses session scoped form beans - the expression would have to
change slightly for request scoped ones.

RE: multipart request issues

[Paul McCulloch]

You're theory is correct. The input stream is consumed as it is parsed.

The process flow doesn't seem to match what I'm seeing (Struts 1.2.4). In
1.2.4 all off this is handled in the request processor - not the servlet.
The very first thing the request processor does (in processMultipart) is to
parse the input stream and put all of the request paramaters in the wrapped
request object.

You can access these with a simple request.getParamater() in
processPreprocess in your extended request processor.

There is still a problem with multipart requests in that the parameters are
never available in JSPs, as they get the original (rather than the wrapped)
request. I overcome this by coppying the paramaters into a request scoped
map.

Hope this is of some use.

Paul

RE: How to run an action automatically like thread ?

Quartz (http://www.opensymphony.com/quartz/) is a job scheduling system
which sounds like it could help you out.

I'd reconsider whether your code should really be in a Struts action. What
are you gaining by using Struts for a non-web bit of processing?

RE: Getting name of form bean?

[Paul McCulloch]

In request scope, under the key 'org.apache.struts.action.mapping.instance'
is an object of type ActionMapping. The name property of this ActionMapping
is the name of the form bean being handled by the current request.

This relates to the form bean specified for the request being processed -
not the the form bean reffered to by . If you need access to that
form bean then  or  might help by exposing form
bean properties.

RE: Best practice for redirecting on session timeout?

[Paul McCulloch]

How does your system know to send the user to the login page in the first
place?

Typically an application (or the container if you are letting it manage
authentication) detectes that a request is made with no session/an invalid
session/a new session. It then sends the user to the login page.

Assuming your security is managed in such a way then you will just need to
set the session timeout in web.xml to make this happen. This will inavlidate
the session after a specified period of inactivity, so the next request that
is made will be with an invalid session id/new session - so the login page
will be displayed.

RE: Injecting actions globally

[Paul McCulloch]

Container managed security will do this for you (though it has some
drawbacks). If you don't need the advantages of container managed auth (such
as automatic propogation of credentials to EJBs) then you should consider
filters to implement this. Filters are a relatively recent servlet feature -
I'd probably disregard posts from 2001.

I believe there is a package called security-filter which does lots of this
kind of thing for you. Search the archives - I've posted a few times on this
subject in the last few months, there is some useful advice & pointers in
those threads.

RE: Multiple forms on one page

[Paul McCulloch]

You can only submit one form at a time. This is an http issue - not a Struts
one.

The solution I have used is to combine all the neccessary fields into a
single form. 

I typically do this with nested objects  - so my form bean would have two
properties "data" & "search" say. These objects themselves contain the
String properties for user input. If you are using JSPs then the nested
taglib makes rendering this stuff easy.

RE: Session now with Filter

[Paul McCulloch]

Hi Scott,

Firstly - changing the subject breaks the threading in many mailreaders!

Securing your application is completely independant of Struts. Neither needs
to know anything about the other - that is why it is such a nice & easy
solution.

Yes - I'm implying exactly what you say I am.

Here's the pseudocode for the filter:

doFilter(...){

if(request.getSession().getAttribute("user" == null)){
//Not authenticated - send all non login request to the
login page
if(request.getServletPath().equals("the login url")){
filterChain.doFilter(..);
}else{
response.sendRedirect("the login page");
}

}else{
//user is authenticated - send the request on it's way
filterChain.doFilter(..)
}

}

That's it.

Paul

RE: Handling Session Expiration Properly

[Paul McCulloch]

Hi Scott,

I can't remeber if it was your question I replied to regarding
authentication where I recommended using a filter to do this, rather than
modifying the request processor. If it wasn't your question then I'd
recommend a serach of the archives. If it was you - I still think modifying
the request processor is not the best solution!

Anyway - some comments on the solution you are working with...

I suggest that you only create the user object and attach it to the session
object when the user successfully logs in. The presence of a user object in
session tells your application that there is a valid user - and who the user
is.

If the user's session expires then the next request they make will be for a
new session (with no user) - so they will be sent to the login page.

There is no need to change the signature of your base action. The user
object is in session which can be obtained from the existing paramater
"request" - there is no need to explicitly pass the user around.

Changing the base action to manage security throws up some other pottential
problems. If you start to use another action variant, such as
DispatchAction, you won't have any security. If you really don't want to use
Filters then I suggest that you modify the request processor to check that
the user is logged in before calling your action, and send them to the login
page if they aren't

Seriously though - a filter is far easier (& web framework agnostic) way to
handle this.

HTH, and feel free to carry on beating this one...

Paul

RE: [OT] How to transpose a table in MS SQL Server 2000

[Paul McCulloch]

Assuming that month, val1 & val2 are the *names* of columns this is going to
be a tricky problem to solve with just SQL. You need to query the system
tables to extract the names of the columns.

The other problem is that the number of columns in your result set needs to
vary depending on the number of rows in your source data.

The only way I could solve this would be procedurally using TransactSQL
(create a temp table, populate it & select from it).

RE: [OT] How to transpose a table in MS SQL Server 2000

[Paul McCulloch]

I don't 100% understand your tables. Where does ID come from (the values 1 &
2 exist in the first view, but 1,2,3,4 in the second).

Are the totals derived?

Give me the SQL for the first view and I'll have a look.

RE: Authorized Site Creation With Struts

[Paul McCulloch]

The two approaches I have succesfully used are container managed
authentication & Filters.

Filters are simpler & more flexible than container managed authentication,
so unless you need a particular feature of CMA (e.g. automatic propogation
of credentials to EJBs) I wouldn't recommend it.

I believe, though I haven't used it, that there is a free package called
SecurityFilter which does lots of cools things for you.

a custom tag. This is fine with 'normal' forms but with multipart forms
(enctype="multipart/form-data") this isn't working.

The code in the custom tag does, in essence, what the RequestProcessor does
- calls org.apache.commons.fileupload.FileUpload.parseRequest().

I believe that the problem is that it is not possible to read the request's
input stream more than once. The RequestProcessor reads the request's input
stream (and puts the parameters in the wrapped request object), so it
appears to not be available for me to read in the custom tag. The Struts
wrapped request is not available (AFAIK) to me in my custom tag.

I was wondering if anyone could confirm my analysis and/or suggest a
solution. 

The workaround I am currently using is to put the request parameters in a
request scoped attribute, in my Action. However this approach couples
together my Struts application with the open source custom tag - not a real
solution.

TIA,

Paul

RE: html: tag four buttons, one action problem

[Paul McCulloch]

I use the approach outlined in
http://www.michaelmcgrady.com/button/jsp/button_talk.jsp. In summary each
button, when clicked, puts their value in a different request paramater - by
looking for the presence of a partcicular paramater a different dispatch
method can be called.

This approach should be relatively easy to use with non dispatch actions
with a few changes to the RequestProcessor.

HTH,

Paul

RE: Is it possible to harvest the form values and populate an act ionform without submitting the form?

[Paul McCulloch]

Could the button on your parent submit the form to the backend with a new
popup windows defined as the "target" attribute (of the html form)? That way
your main form values are sent to the backend, but the results (i.e. your
wizard) is shown in the popup window.

RE: RequestURI (Action not JSP)

[Paul McCulloch]

I don't think you need to do this. If you miss out the requestURI attribute
then the current request's URI is used, which will (in a typical struts
application) be the URI of the last action - not the JSP forwarded to.

If you need more help with this then post to the displaytag mailing list.

RE: Hibernate: when 2 users simultaneous edite

[Paul McCulloch]

This is well of topic - please use [OT]in your subject in the future.

This is a classic multi user application problem. The problem is commonly
known as 'lost update' & an often used solution is optimistic locking.

In my experience using a 'version' column on each table is easier to manage
than timestamps. Just increment the version number when you do an update &
check that the current version on the record is the same as the retrieved
version prior to updating.

Hibernate has this functionality build in  - see

RE: Displaytag, number formatting, and sorting

The latest version of displaytag supports a sortPropery setting. This allows
you to display a nicely formatted value but sort on the underlying data.

Column decorators are very rarely required now.

RE: Accessing my form from an included page

[Paul McCulloch]

Frank,

Although your solution would work I'd be apprehensive about any solution
which involves doing anything manually at the start of each action. I'd
suggest that anything that needs to happen for each & every action is better
suited to a modified RequestProcessor, or a Filter. 

As you want to deal with all requests - not just actions, I'd suggest that a
Filter would be the way to go.

My apologies if I'm trying to teach you to suck eggs :-)

RE: Accessing my form from an included page

[Paul McCulloch]

1) You'll pretty much always have a valid session - the container will
create one for you if it isn't already there. What you need to do is
establish if an *initialised* session is there. 

One way to do this would bet to, in your initialise session action, create a
session scope attribute to say so:
request.getSession.setAttribute("ValidSession", Boolean.TRUE);

To check that you have a valid session I'd implement a Filter
(http://java.sun.com/j2ee/sdk_1.3/techdocs/api/javax/servlet/Filter.html)
which would check for the presence of the attribute. In it's absence send
the user back to the initialise action.

All of this pre-suposes that you *don't* have security requirements. If you
do then look into a security framework, such as container managed security,
which will very probably already have things in place to deal with your
scenario.

2) Don't know. Check the group archives
(http://marc.theaimsgroup.com/?l=struts-user&r=1&w=2) - breadcrumbs have
come up before.

RE: Accessing my form from an included page

[Paul McCulloch]

I didn't notice this in the thread - but I didn't read it in depth as it was
pretty long.

I see more risk in one of my developers forgetting to add the call than in
the attribute name Struts uses changing. If that's a real concern why not
use a custom request processor to put the mapping in an attribute whose name
you define?

RE: Accessing my form from an included page

[Paul McCulloch]

When you execute an action the name of the action from used is set in a
request scope attribute "org.apache.struts.action.mapping.instance". It's a
fairly simple matter to get the actual actionform object if you know the
scope. For instance, all my forms are session scope so I can get the
just-used form with:



If you don't know the scope then you'll need a bit more logic to get the
formbean.

Does that help?

HashMap doesn't implement the Collection interface, and has no method for

RE: obfuscation Struts config

[Paul McCulloch]

Won't obfuscating your classnames make any analysis of a stack trace, for
example, very difficult?

Anyway - I would expect that any commercial J2EE code obfuscation tool which
changes classnames would know how to modify the XML files. EJBs for instance
are also referenced, by name, in xml config files.

Otherwise I reckon a bit of sed should be able to do a simple (or complex!)
search & replace to meet your needs.

RE: server shutdown

[Paul McCulloch]

I wasn't aware that Tomcat had any functionality related to running external
programs. I can tell you that I have successfully called external programs
(our own win32 commandline exes) from Tomcat and JBoss/Tomcat (using
Runtime.getRuntime().exec() as you do).

I think that, unfortunatly, it's down to your code or environment. I'd start
simple  - a command line program that writes something to a file - and build
up to your goal from there.

The attribute in org.apache.struts.taglib.html.BEAN is set by the
 tag. This is how the other  tags know which form bean
they are dealing with.

I'd be interested to know why the other html tags are made aware of the form
bean this way, rather than directly asking their enclosing form tag. Any
ideas anyone? The only thing I can think of is that it means that
dynamically included pages can still use the html tags to reference the
parent page's form.

RE: server shutdown

[Paul McCulloch]

I'd start by getting things working running tomcat *not* as a service. Once
that is done switch to using a service. 

If you look at the service Log On control panel you'll see a "Allow service
to interact with desktop" checkbox. This will need to be set for you to see
a program running on your desktop. That option can only be set for the local
system user - not adminsitartor.

RE: server shutdown

[Paul McCulloch]

It looks like you are getting the return code from cmd, rather than
shutdown. Could it be that the process you spawn doesn't have it's
environment correctly set up - maybe it can't see shutdown?

I'd try 1) changing my call to exec to call shutdown, with a full path,
directly rather than getting cmd to do it. 2) Call a batch file instead -
have the batchfile echo the environment to a file 3)Try and get the Java
process to create an interactive cmd for you (maybe cmd /k) - that way you
can try various commands in the same context that the Java process can.

RE: loosing request attributes from jsp to action

[Paul McCulloch]

I may be wrong, but it sounds a lot like you are misunderstanding the scope
of the request object. Apologies if I'm wrong - please ignore the following
egg-sucking tutorial!

The request objects life starts, on the server, when the servlet container
recieves a request from the user's browser. That request object is valid
until the end of all server side processing (i.e. until the page is rendered
on the browser). Nothing set in one request is visible in any other request.

In the example you give you are copying, whilst your page is being rendered,
one request scope attribute (index) to another request scope attribute
(identifier). What you aren't doing, as Rick says, is putting that bit of
information anywhere that can be used by a subsequent request. You need to
render the index in such a way that it is automatically sent back to the
server on subsequent requests.

I think the easiest way to do this would be to declare the index as a
property of your form bean. Your action could set this form property (rather
then setting the request scoped attribute as it dow now). The 
struts tag will take care of preserving this value for subsequent requests.

RE: Best practice updating data in webapps?

[Paul McCulloch]

The approach you describe is known as optimisitic locking. 

The alternative approach is pessimistic locking, where you mark the records
to be updated as locked at the time you get the records from the datasource.
No other process will be allowed to lock the records at the same time - so
no two users can update the same record at the same time.

One problem with using pessimistic locking is how to deal with a user who
locks a record, but never releases it. In a web based application this is
very likely to happen - it's difficult to stop a user just killing their
browser. 

Optimisitic locking is generally easier to implement & less dependant on the
datasources involved. So, unless you have a problem which can't be solved
this way I'd go with optimistic locking.

RE: Conditionally disable form input.

What you are suggesting will only work if the form is submitted after the
checkbox is checked - probably not what you or the user would expect to
happen.

I'd try and use JavaScript to achieve the same functionality on the client -
the relevant event on the checkbox field could modify the disabled flag of
the text input.

RE: how to replace return in a string while use nested:write and bean:write

[Paul McCulloch]

The Jakarta Regexp taglib
(http://jakarta.apache.org/taglibs/doc/regexp-doc/intro.html) should allow
you to do the neccessary search-and-replace to creat a JavaScript compatible
string.

RE: debugging with Struts

[Paul McCulloch]

I think it is actually the source path of the *debug* configuration you are
using. 

I just spent a good 20 minutes figuring this out - I've just upgraded to
1.2, but my debug source was pointing to 1.1 which caused a bit of
confusion.

RE: tab UI controls for struts

[Paul McCulloch]

I had a look for such things a few weeks ago. My requirement was for a
server side implementation - i.e. one that didn't execute the content of
hidden tags. I couldn't find anything that met that requirement.

I did find a pretty cool looking client side implementation at
http://www.pintexx.com/

I've implemented my own tab control as a bunch of custom tags. There is no
inherent dependancy on Struts - the state is maintained in hidden html
fields & a change of tab is indicated via request parameters. I'm not in a
position to share any of this code I'm afraid, but I'm more than happy to
discuss the design etc.

RE: cleaning session

What a nonsense sentence! What I meant to say was:

That isn't the purpose of the (confusingly named) reset method. Reset is
there to, typically, deal with the way html forms submit checkbox fields
(they don't submit anything if they are null).

RE: JSTL and Tiles

Try using request scope (rather than the default of page) when you use JSTL
to set your attribute value. Changes to the named attribute will be picked
up by any code which is executed afterwards.

RE: Refresh problem

[Paul McCulloch]

The token is set in a session scope attribute named
"org.apache.struts.action.TOKEN". It should be relatively straightforward to
include it's value within the link, as a parameter named
"org.apache.struts.taglib.html.TOKEN". I suggest you take a look at the
TokenProcessor class if you have any issues getting this working.

As this is no longer Struts related can I suggest that you take this to a

RE: Compilation of JSP at time of deployment?

[Paul McCulloch]

JBoss/Tomcat (which I assume you are referring to) has default behaviour
whereby the compiled JSPs get deleted on graceful server shutdown. Killing
the process hard gets round this issue, or there is a config setting which
disables this. You need to edit the tomcat config file
($JBOSS\server\default\deploy\jbossweb-tomcat41.sar\META-INF\jboss-service.x
ml) and add:

  false

Between  2000 & 

With this change you'll only have poor performance the very first time a
page is accessed, regardless of reboots etc.

RE: Clean way to obtain a property's value...

This is quite a FAQ. The neatest solution propsed was, IMO, the 'bind' tag
in the Jakarta Unstandard taglib
(http://jakarta.apache.org/taglibs/sandbox/doc/unstandard-doc/index.html#bin

I curently use the  + scriptlet solution you propose.

RE: load balancing and definition of a request

[Paul McCulloch]

It sounds like you may have a misunderstanding of the interaction between
your browser and a web server. 

Let's just talk static content first. You request a URL for an html page;
the server sends the page back to you. That's a request. Now if the html
page you recieved contains 2 pictures then your browser will send off
another 2 requests to the server to get those images. So that was 3 requests
in total.

Now stick a load balancer between your browser and the servers. All this
will do is somehow allocate some requests to some webservers and some to
others. How the load balancer does this is it's business, and the web
servers don't care where the requests come from.

Now let's think about a web application. In this case we have the idea of
may sessions - but theses are just a way for the server & browser to
logically group together a bunch of discrete requests. There is no concept
of a session at the http level. 

The load balancer may or may not be session aware. To be aware of JSP
sessions it needs to know that it should look for a "jsessionid" attribute
in the requests and responses. 

If the loadbalancer is session aware & has 'sticky sessions' enabled then it
will always route requests for a particular session to the web server where
that session started. If sticky sessions are disabled then it will just send
your requests to an arbitrrary web server.

As you point out, the problem with using non sticky sessions is that session
data has to be replicated to the other nodes in the cluster. This is often
done when you call session.setAttribute()  - the replication will happen
then and there, or it may be done on a periodic basis. 

Due to this issue, and my relatively heavy use of session data, I've gone
for a sticky session load balanced solution rather than a clustered
solution. So, I can't tell you much more about the detail of session
replication, other than it's container specific.

Have a look at the mod_jk apache load blanacing ,odule for tomcat -
http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jk2/index.html.

RE: [OT] synchronous form submit in a popup so parent refreshes p rope rly

[Paul McCulloch]

You could make the response from the submit be an html page which executes
the relevant (parent.reload; close) Javascript. 

Alternatively you could submit the form on the popup window so that the
response of this submission was displayed in the parent window (via the
'target' attribute of the form tag). You'd want to define the forward for
this action to be the refresh action you want your parent to perform.

RE: Question with beans and iterate

[Paul McCulloch]

Although this is (probably) possible your object model is making things more
difficult than it needs to be. 

I would consider remodelling this as a single Map of Items where each Item
has, in addition to it's other properties, a Collection of SubItems. This
will be fairly easy to render using the JSTL iteration tags (iterate over
the Map of Items, within that iterate over the current Item's SubItems).

HTH,

Paul

RE: ActionForm: simply calling reset() or have to recreate one ?

You don't event need that. As I said - servlet is a protected instance
variable of Action, so you can just use 'servlet' in code in your Action

RE: The jar files in the C:\jakarta-struts-1.1\contrib\struts-el\ lib directory

[Paul McCulloch]

These files are need if you wish to use JSP EL in a JSP 1.2 container. If
you use a JSP 2 container then EL is supported for the standard struts tags
(by the container rather than the tags themselves). See
http://struts.apache.org/faqs/struts-el.html for more details.

RE: ActionForm: simply calling reset() or have to recreate one ?

[Paul McCulloch]

I think it was me who pointed you down that route to destroy & recreate a
form bean to clear any data in it.

reset() is not used for this purpose -  read up on what reset() does. 

"servlet" is a variable of Action and is available in all methods of your
own Action classes.

RE: Somewhat OT: moving Struts app from BEA to Jboss

[Paul McCulloch]

I use 3.2.3...

The debug messages can be turned off by playing with the log4j config file
in C:\jboss\jboss-3.2.3\server\default\conf\log4j.xml

You should deploy your application (as either a .war file, or a .war
directory) by copying to C:\jboss\jboss-3.2.3\server\default\deploy. I have
never seen this issue you mention regarding deploying jars under
WEB-INF/lib.

Is your app a simple web application, or an EJB app?

RE: LookupDispatchAction (Newbie)

[Paul McCulloch]

I'm confused. Looking at the wiki (ImageTagUtil class) it seems that a non
null command will only be returned if there is a request parameter with name
ending in ".x". My understanding of html is that only  tags send the x & y coordinates to the server in submission.

What am I missing? 

Thanks,

RE: Bean's get method with parameter

[Paul McCulloch]

1) Oops. That was from memory
2) When the browser makes a request it sends a list of accepted locales.
JSTL will look at this list to determine how to format the date. In IE this
is configured via Tools:Internet Options:Languages.

RE: Possible to change input path in actionForm validate?

[Paul McCulloch]

One way to do this is to have multiple actions defined in struts-config.xml,
each using the same Action class. Each action can have a different input
JSP.

RE: Bean's get method with parameter

[Paul McCulloch]

A getter with a paramteter is not a bean property, and so won't be
accessible with the usual tags.

I'd suggest that the formatting of your date is the responsibility of your
view layer, and not the form bean. The easiest way to do waht you ar after
is to use the JSTL's  tag:





This will automatically pick up the request locale.

RE: More than 5 Arguments

[Paul McCulloch]

Use fmt:message & fmt:param tags instead of the Struts tag. If you can;t use
JSTL then extend the bean:message tag.

Hi 

My question is how to print a message on the page through resource bundle
which has more than 5 arguments. 

 Tag support only 4 arguments. Any help with example will be
appreciable. 

Thanks

RE: SV: strange behavior: bug or me?

[Paul McCulloch]

No disrespect intended - but I'd be inclined to look at my own
code/environment before I started blaming the struts taglibs!

When I get into this sort of position I tend to remove all traces of my jsp
from the container (including the generated servlet etc), redeploy & restart
the container. If that doesn't give me any joy then I'll debug into the
taglib in question. To my mind this is a huge advantage of using components
where I have access to the source.

RE: [OT(?)] Comparing against a typesafe enum in JSTL

[Paul McCulloch]

I've asked this before on the list and didn't get a neat answer. I've
resorted to using c:set & scriptlets to extract the value from the static
and store it in a scoped attribute for use with JSTL.

RE: how to reset form

[Paul McCulloch]

The method I use to is to remove & recreate the form bean. I wouldn't use
the reset method - this is not for resetting the form bean in the way you
suggest - it is called for you by Struts. Here is the method I use to do
this:

public ActionForm recreateFormBean(ActionMapping mapping, ActionForm
form, HttpServletRequest request,
   HttpServletResponse response) throws
ServletException {

String attr = mapping.getAttribute();
String scope = mapping.getScope();

if (scope.equals("session")) {
request.getSession().removeAttribute(attr);
} else {
request.removeAttribute(attr);
}
ActionForm f = RequestUtils.createActionForm(request, mapping,
mapping.getModuleConfig(), servlet);

if (scope.equals("session")) {
request.getSession().setAttribute(attr, f);
} else {
request.setAttribute(attr, f);
}
//call reset, as struts would do befor the use of any form bean
f.reset(mapping, request);

//populate the form bean with any request parameters - from
RequestProcessor.processPopulate
if (mapping.getMultipartClass() != null) {
request.setAttribute(Globals.MULTIPART_KEY,
 mapping.getMultipartClass());
}
RequestUtils.populate(f, mapping.getPrefix(), mapping.getSuffix(),
  request);

// Set the cancellation request attribute if appropriate
if
((request.getParameter(org.apache.struts.taglib.html.Constants.CANCEL_PROPER
TY) != null) ||

(request.getParameter(org.apache.struts.taglib.html.Constants.CANCEL_PROPERT
Y_X) != null)) {
request.setAttribute(Globals.CANCEL_KEY, Boolean.TRUE);
}

return f;

}

Is using forward as an exception handler's path valid? I didn't know you

Anyway, I'd reduce the complexity of what you are doing: Start by using an
html page as your path, then try a JSP, then an action.
