Re: Parsing Error for struts-config.xml

[Ivan Siviero]

I'm having the same exception on SunOS 5.8 and Weblogic5.1sp9 which is still
unsolved.
I suppose you already have the xerces.jar in the classpath.
Let me know if you get a solution on this.
Thank you.
Ivan.

RE: Struts Validator NoClassDefFoundError

[Craig Raw]

I am using the commons-validator.jar from the Jakarta site. (Sorry,
missed this out when typing the contents of my WEB-INF/lib).

Since I only used the Validator for the first time after its movement to
Commons project, I doubt I have any old com.wintecinc.struts classes
around.

What version of the Struts Validator are you using? 
Package names were changed at some point from
com.wintecinc.struts.* to
org.apache.struts.validator.* (1/14/2002).  When this
was done, most of the validator was moved to the
Jakarta Commons Validator
(http://jakarta.apache.org/commons).  I would double
check the files/package names in the jar you have.

I'm storing blob data into the database and using JImageMagick to return
image of different formats on the fly.  Each time I have to retrieve an
image included in a page (with other text/html contents), I have to call
the retriever Servlet or jsp from the  tag.

However, I did not hardcode the table/id info into the Servlet so
everytime I call the servlet I have to pass the table name and at least
(if the former is hardcoded) the image id to the img tag, like



Is there any way to hide the query info?  in a session manner or some
other more elegant way in Struts?

Re: Struts and encryption

Many database have their own extensions for encryption, or one-way
hashing, used for things like password storage. That's probably the best
choice you could make.

RE: getting ArrayList elements as objects

[Domen, Ken]

I was hoping by reflection that my sub-object would be re-created
automatically.  This was not the case.
I had to take all the attributes and recreate the sub-object in the
ActionClass and then attach it to the
parent class.

So the jsp code stays "clean" and struts-like

But in the UpdateMaterialAction class, there's a bit of work:

***
//2.  Grab request params from Bean.  Use this same bean to
repopulate
MaterialBean myForm = (MaterialBean)form;

//3.  Create the Material Object along w/ child Substances Objects
and
// then call business logic in EJB 
try
{
BusinessFacadeHome bhome = this.getBusinessFacadeHome();
BusinessFacade facade = bhome.create();

//1.  This is the parent object w/ parent attributes
Material m = new Material();
m.setMaterialID(myForm.getMaterialID());
m.setSupplierMaterialName(myForm.getSupplierMaterialName());
m.setNikeMaterialName(myForm.getNikeMaterialName());
m.setSupplierProductID(myForm.getSupplierProductID());
m.setNikeProductID(myForm.getNikeProductID());
m.setMaterialDescription(myForm.getMaterialDescription());
 
m.setFinalProductApplication(myForm.getFinalProductApplication());
m.setRemarks(myForm.getRemarks());
m.setMaterialStatus(myForm.getMaterialStatus());
m.setLastUserUpdate(myForm.getLastUserUpdate());
m.setConfirmingUser(myForm.getConfirmingUser());
if (myForm.getExceedsSubstanceLimit()) {
m.setExceedsSubstanceLimit("1"); }
else { m.setExceedsSubstanceLimit("0"); }

//2.  Struts does not automatically re-create sub-objects for
you from the jsp-- this doesn't work
ArrayList list = myForm.getSubstances();
System.out.println("list.size(): " + list.size());
Iterator i = list.iterator();
while (i.hasNext())
{
Substance s = (Substance)i.next();
System.out.println("s.getCasNumber(): " + s.getCasNumber());
}

//3.  So we have to reconstruct the sub-object and attach it to

I want to be able to get (after a submit) the values of the iterator

an ArrayList in bean Material.  

How do people achieve this?  Or is there a work around?

For Password encryption (which is one way, you can never get back the original 
password, given the encrypted string), there's one
called JCrypt.

What's a good practice to reuse formBeans with validation

[@Basebeans.com]

Subject: What's a good practice to reuse formBeans with validation
From: "Tea Yu" <[EMAIL PROTECTED]>
 ===
Hi, consider the following scenario:

a countryForm bean contains properties "id" and "name"
actions to 1) insert, 2) update and 3) delete countries (not likely to
happen except to remove wrong/test inputs)

if I allow my users to delete a country by id (maybe a hyperlink), then I
suppose the name field will be null.  How should I handle such a basic
validation in countryForm as name shouldn't be null in case 1) and 2) but
could be null in case 3)?  The same question applies to id field in case
1).

Is this a business logic and not to be handled in form bean?  Thus only
test if id is an integer:

if(id != null){
try{
Integer.parseInt(id)
}catch(NumberFormatException nfe){
//chain up errors
}
}


in the actionForm:

if("Delete".equals(mapping.getParameter())
//test id==null


or should I turn to struts validator (which I guess rules could be
included in the form)?  or to use 3 different formBeans?  |o|

Nice day!

live progress...

[Keith Chew]

Hi

I would like to implement a live progress on a JSP, something like:

time = 0s
*
Synchronizing database...

time = 5s
*
Synchronizing database... DONE!
Sending mail to keith...

time =10s
*
Synchronizing database... DONE!
Sending mail to keith... DONE!

Essentially, I need to flush the ouput to the page correct? Can I do this
from the Action class? I doubt this can be achieved because the MVC
architecture forces you to prepare the entire data for view. So, you cannot
flush part of the view from the Action.

Anyone done this kind of thing?

I18n / Chinese / Struts

[Tony Li]

Hi all - 

After reading some of the posts on getting internationalization working,
I've got my struts app using the appropriate resource file
(resources.properties and resources_zh.properties) depending on the
locale of the user.  

What I'm having trouble with is with the file I'm inputting into the
native2ascii.  I've been using NJStar Chinese WP to create my
resources_zh.properties.  I've tried saving the file in GB Text, Big 5
Text, UTF8 Text, and all the other available formats.  I then feed this
file to native2ascii to get my resources_zh.properties.  All I'm getting
is garbage in IE when I hit my test page.

I've followed the example on this site:
http://www.anassina.com/struts/i18n/i18n.html and added

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

to the top of my test jsp.  I've tried all the different IE
View->Encoding options and I can't get the chinese text I originally
entered into NJStar.

Any ideas or suggestions?

Thanks,

Tony Li

You might take a look at JDOM.  It's a bit easier to use than the straight DOM

html:error and html:text enhancements

[Jonathan Fuerth]

I have two quick questions about the html:errors tag:

1. Has anybody thought about implementing a "remove" attribute on the
   errors tag that removes the ActionError objects as they're printed?
   That way, you could report all of the property-specific errors
   alongside their form input boxes, then render the leftovers at the
   bottom of the form with a simple  tag.

2. Has anybody thought about implementing a "printErrors" attribute
   on the html:text tag?  This would have to mesh well with the
   "indexed" property to report all the errors encountered in a
   collection of indexed text boxes.

If nobody is currently working on this, I'd be happy to do it.  I'm
especially interested in input from the Struts maintainers so that I
can do the modificiation properly.  That way, it could be integrated
with future releases.

Thanks!

and keeping the value on errors

[Matt Raible]

This might be considered off-topic, but here goes.

Does anyone have a solution for keeping the file path in a 
rendered by a  tag?

I noticed with the Validator, it is not possible to validate the user has
selected a file.  Therefore, in my action class, I am extracting the filename,
and checking to see if it is blank.  If so, I route them back to the first
page, and tell them they need to select a file.

However, the file they selected is not in the field anymore.  I'm assuming this
is a browser thing, since I know you cannot set a value using javascript
(against security on this type of field).

Does anyone have a workaround for keeping the original value in the field?

Thanks,

Matt

Hi all,

I'm using Struts on a project in the company. The Internacionalization for
the messages and labels on the Web pages work fine and we didn't have much
problem.

But for the internacionalization of some number formats (write 1.000,00
instead of 1,000.00, etc) we had to set somethings hard coded because we
didn't find support on Struts for this kind of thing.

Do you know if it's possible to let Struts do by himself the formatting of
numbers, dates, etc. automatically using the Locale catched from the
session, like it does for the messages and labels?

Thanks in advance,

Re: [Off Topic] Poolman Setup

[cahana]

Looks like it can't find your poolman.xml file.  We jar poolman.xml and
stick the jar file in the WEB-INF/lib directory.  That way, when the app
starts up, poolman.xml will get loaded into the classpath.

Subject: [Off Topic] Poolman Setup


I've done everything (I think) that poolman requires in order to function,
and yet it does not.  After placing only the required jars into my \lib
folder, and having no success with Poolman starting, I threw all of them in.
It still doesn't work.

I wasn't at all sure, from the documentation, where I should poke the
poolman.xml file.  Initially I had it in my WEB-INF directory.  Then, I
copied it to the \lib directory. Still no luck.

Every time Poolman is started, I get the same exact error - a null pointer
exception.  This occurs when poolman is calling parseXML from
loadConfiguration.  The relevant piece of the stacktrace is:

java.lang.NullPointerException
at com.codestudio.management.PoolManConfiguration.parseXML
(PoolManConfiguration.java:121)
at com.codestudio.management.PoolManConfiguration.loadConfiguration
(PoolManConfiguration.java:75)
at com.codestudio.management.PoolManBootstrap.
(PoolManBootstrap.java:61)
at com.codestudio.management.PoolManBootstrap.
(PoolManBootstrap.java:54)
at com.codestudio.sql.PoolMan.start (PoolMan.java:97)

The rest of the stacktrace goes into my servlet - which worked fine before I
tried to kick off Poolman in it's init method.

I have also tried not calling start, but, instead, just allowing Poolman to
do it's 'lazy' initialization - same exact result.

I would be most appreciative if someone out there could give me a 'heads
up'.

I'm running Tomcat 4.0.1 (I can't see why that would matter) and JDK 1.3.

Thanks!

I'm no expert (having just picked up poolman a week ago) but, it appears
to me that you don't have poolman.xml in the right place. It needs to be
in either of the following places:

1. In the WEB-INF/classes directory (this is what I do)
2. Jar'd up, and then put the Jar in the WEB-INF/lib directory (as
opposed to what you tried, which is putting the un-jar'd XML file in the
lib directory).

Form Based authentication with STRUTS and WEBSPHERE

[BinhMinh Nguyen]

Hi,

My webapp is implemented based on struts and deployed
to WebSphere.

I am using custom-user-registry  to protect web
resource. I have setup
everything. when start the Admin Console, it asked me
for the user
name and password, I entered those parameters and it
let passed that
point, so I assumed that the custome user registry I
implemented 
works.


But when tried to access the protected resource, it
seems like the
application entered some sort of infinite loop, the
browser keeps
browsing and browsing...
and it seems like it would never stop !:(


I am not sure that I can use .do in websphere??? but
it works fine in weblogic. 


/login.do
   
/loginerror.do
 





The application.xml defines the role, "role-fn-user", 

This role is mapped to a group in the database at the
time of
deployment (I selected option "select users/groups" in
the "user role
mapping" panel at deployment time. I believe that the
Admin Cosole
does look up for the group in the DB using the custom
Registry because
I did test change the value of the group in the group
table and it
does return the right value if I made the change.

I am sure that I missed something or have done
something wrong. Please
help me sole this problem, I spent the last three days
trying to solve
it, but I cannot

Thanks in advance

[Off Topic] Poolman Setup

[Eddie Bush]

I've done everything (I think) that poolman requires in order to function, and yet it 
does not.  After placing only the required jars into my \lib folder, and having no 
success with Poolman starting, I threw all of them in.  It still doesn't work.

I wasn't at all sure, from the documentation, where I should poke the poolman.xml 
file.  Initially I had it in my WEB-INF directory.  Then, I copied it to the \lib 
directory. Still no luck.

Every time Poolman is started, I get the same exact error - a null pointer exception.  
This occurs when poolman is calling parseXML from loadConfiguration.  The relevant 
piece of the stacktrace is:

java.lang.NullPointerException
at com.codestudio.management.PoolManConfiguration.parseXML 
(PoolManConfiguration.java:121)
at com.codestudio.management.PoolManConfiguration.loadConfiguration 
(PoolManConfiguration.java:75)
at com.codestudio.management.PoolManBootstrap. (PoolManBootstrap.java:61)
at com.codestudio.management.PoolManBootstrap. (PoolManBootstrap.java:54)
at com.codestudio.sql.PoolMan.start (PoolMan.java:97)

The rest of the stacktrace goes into my servlet - which worked fine before I tried to 
kick off Poolman in it's init method.

I have also tried not calling start, but, instead, just allowing Poolman to do it's 
'lazy' initialization - same exact result.

I would be most appreciative if someone out there could give me a 'heads up'.

I'm running Tomcat 4.0.1 (I can't see why that would matter) and JDK 1.3.

Thanks!

Keith, they're not the same thing, by any means. As you said, if you use
your method:

you get a "too many servlet includes `/template.jsp'" error. This is doesn't
really suprise me at all - you're basically trying to use something which
blatantly isn't a template, as a template.

However if you use the method I outlined in my examples, i.e. you "put"
content into a template, whether this content is a .jsp or an action mapping
url - it works.

Honestly, just use  as it is documented and your problems will
be solved.

You need to do the following:
1. Create an action mapping like this in struts-config.xml:

2. Create your template file "/mytemplate.jsp" something like this:
<%@ taglib uri="/WEB-INF/struts-template.tld" prefix="template" %>




3. Create your page "/thePage.jsp" something like this:

Matt, thank you very much for trying this out. I appreciate the time you are
spending to help me track the problem.

Can you give this a go:

In the address bar, type a *.do address, eg
http://localhost:8080/test/page1.do

This will call Page1Action, which forwards to page1view.jsp

In page1view.jsp, it will have your template which inserts shownews.do.

I believe this will fail.

If you have a JSP in the address bar, it's fine. But with a .do, it's not.

I have using the 26 Feb 2002 snapshot.

RE: Application Scope Variables

Hi

  The HttpSession does not have a servletcontext, the servlet has, and you
can get to the servlet from the ActionForm with the getServlet() method.

So
Object o =
 getServlet().getServletContext().getAttribute("attribute_name");

should work
  (has not tried it "live" though :-) )

Hi Keith.


I look at the system as having several complementary models, controllers and
event triggers.  Struts Action, ActionForm, and submit triggers are among
them but not the only ones.  In other words, I don't see Struts Actions as
being the only system entities that can respond to event triggers, and
ActionForm beans are not the only data containers.  As you have discovered,
the struts objects are really only good at responding to a subset of the
possible events, and handling a subset of the pages data.  I think that is
intentional rather than a flaw.

If you buy that, then you can use "page load" as an event trigger, and your
own home grown "NewsModel" bean.  Some other home grown controller can go
get the data and push it into the news bean.  These homegrowns cause you
trouble when you try to force them to be children of Action and ActionForm.

So I'm suggesting only that the tag load and display the data from the news
model.  However, if you wish to have the "page load event" trigger a model
update, the lines get a bit blurry because I'm using the custom tag's
execution thread to kick off the model load, and refresh the display.
Although that thread is involved with "double duty"  the object model is
still clean --- the custom tag is just rendering data, and some other
controller logic is getting the data.

You could use other events to load the news bean such as user log in,
periodic polling, etc.  Not sure what your requirements are here but I'm
guessing you want the news updated on each page load.

OK I'll shut up with the philosophical stuff and let you get back to the
real solution that Matt helped you with :)

Good Luck

/Ross

Hi Ross

Good comments.

You see, with custom tags, there are several problems:
- For each different parts of the template, I need to create a custom tag
- This custom tag is actually what an xxxAction class is meant to do, ie
retrieve data from a database and prepare the data for view
- If I later decide not to put news in the template and put it in a separete
page, I need to port the taglib code to an xxxAction class. Not very
flexible.
- taglibs from Struts point of view, only renders data for viewing. It
should not be performing model work, which should really be in the xxxAction
class.

So, I can see that Struts was designed to handle "user invoked" actions, not
"code invoked" actions.

Any more thoughts?
Keith

Consider rethinking the philosophy that all data rendered in the JSP must
come from an ActionForm.   In my mind the ActionForm generally represents
the editable data for the page displayed to the user.  There's no problem
with displaying data from other sources on the same page - especially read
only data.

For news I would simply use a custom tag to get it and display it.

Put another way, I wouldn't want to have to set up a bean with "setNews" and
"setMemberCount" when I have no intention of allowing my application to edit
those values.

Hi

Struts provides us with a nice MVC architecture, where:
- a user's click maps to an Action
- based on the results, the user is forwarded to the view

Now, I have a template.jsp which all pages will use. The template will
contain some views that are common to all pages, eg:
- Latest News
- Site visits

To retrieve these information, it gets them from the database. However,
there is no user click to invoke the action. This is where the limitation of
Struts comes in. Let me explain:

In the template.jsp, we can have:



In news.jsp we can access the database and retrieve the news for display.
This breaks the MVC pattern, since the view is accessing the model.
Alternatively, we have have this in the template.jsp:



This will call the NewsAction which accesses the database, and forwards the
results to the news.jsp for display.

This is a great concept, but it does not work. Struts does not allow
multiple forwards (this happens when the c

[Domen, Ken]

Here's my problem:

During a display of the page, I use:








But I also want to update the values.   
The html then becomes:





















So now, the bean doesn't find any getSubstanaces(ArrayList), it only sees a
bunch
of casNumbers and substanceNames.  If I say, getCasNumber() in the bean, it
only
gets the first one.

How do people deal with this in struts?

does

I would have thought putting enough debug messages would highlight the

I'd guess it's not even executing your debug code because you'd get a null

Intriguing! (Most likely something really obvious... bit I can't see it.)

RE: Struts Community Opportunity

[Yu, Yanhui]

Ghoot,

As a newcomer, I thank you for this proposal to re organizing the struts
documentation.  I know it is probably my own fault that I can't understand
exactly what the doc says sometimes but I still hope the doc can show the
new users easier way!

Thanks again,
Yanhui

Subject: Struts Community Opportunity


Hello all

I think there is an opportunity here, particularly with the imminent 1.1
release. I imagine there are going to be a whole bunch of new questions when
1.1 is released. There IS a lot of documentation for Struts. The work Ted
and others have done is great. But perhaps a new perspective on the docs
(particularly for newbies) might be prudent.

I know from my own experience that how these docs are organised and
presented can have a big effect on their usefuleness. Those of us who've
been using Struts for a longest can see how the user base has increased
dramatically, and I can only see this increasing with the release of 1.1.
Perhaps now is a good time to consider possible changes/refactoring of the
docs that would help inform new users and 'alleviate' some of the burden on
the list.

I know the docs as is are good, but thats easy for us to say when we know,
pretty much, how it works and hangs together :)

I'd be happy to offer some suggestions and effort in this regard - and I'm
sure others would too. I have experience in organising this type of content
on a large scale - especially for 'newbies', so maybe I have a different
perspective.

I'm not intending to step on anyones toes ! Any new work would obviously
build upon the existing site and Ted's great site.

Now for a shameless plugChiki (http://chiki.emaho.org) is being
developed by myself and others, and this is one of the ways it can be used,
for community building and content management. Perhaps somewhere down the
line we could have a Struts Community site powered by Chiki, with all the
relevant resources. As it is based upon Wiki this content can be dynamically
updated and managed, and there is suitable access control provided ! (well
in a release coming out very soon) Think 'The Server Side' devoted to
Struts. It would dramatically reduce the load on the mailing list, as well
as serving as a focal point for all things Struts. I imagine there would be
a group of administrators obviously, but it would also allow others to
contribute too, thereby lightening the load on everyone helping with the
list. I could go on and on about the benefits !

I'm not saying Chiki is the only answer, but I'm just volunteering something
that seems a great fit for the 'problem'. In the next 4-6 weeks Chiki will
be ready for such usage.

I'd love to see a Struts community using chiki (since it's built on Struts),
taking the whole Struts experience to a new level, one which can not only
cope with increased user base, but would positively thrive on it.

Even if people dont think this is the way to go, then I'd still be happy to
offer advise perspective and effort re the Documentation.

Please let me know what you all think

Thanks

Ghoot

You seem to vent a lot of frustration at newbie users. So they havent read

Bear in mind that for a newcomer, the documentation can be confusing and

UltraDev 4.0 Custom Tag Library Extension

[Soledad Villa]

Hi all,
I've tried the extension UltraDev 4.0 CTLX provided by jakarta and I
happened to have many problems:
1) the TLDParser has code errors:
   a - it's importing a class from xerces.jar that doesn't exists
   b - overrides the init method but it's not invoking the
super.init(config) method

Once I've fixed those errors, I was able to see the custom tag libraries,
but there is a problem remaining: when inserting a new tag, the JspParser
from jakarta "rewrites" the jsp code and eliminates some parts of the tags.
For instance:  is changed to .

So, it's not working very well.
The question is: anybody knows a tool, extension or whatever that actually
work with struts tags in order to see the page?
Or at least, anything to solve the problem I've been talking about?

Thanks in advance,
Sol

RE: Struts Web App Challenging user with BASIC Auth

[Satish Jeejula]

David,

I have configured server.xml correctly. 

This is what I had to do to make it work.

In my web.xml file of my web application, the
security-constraint/web-resource-name/url-pattern element was set to my
context. It looks like the security is applicable to anything under that
context.

For example, if my context 'url-pattern' is /myContext and if I set the
security-constraint/web-resource-name/url-pattern to /myContext .. it does
not work.

So I changed the url-pattern to /myContext/jsp/*. So whenever I try to
access my index.jsp page, it will challenge the user.

I am not sure if I am doing it the right way .. but this is what I have
observed and this is how it working.

Any suggestions are appreciated.

thanks,
Satish

You can use redirect="false" to make it a forward, which is what you
want most of the time.  I believe that false is the default value.

I am stuck up on how to achieve dynamic forwarding. Issue is in action
mappings of struts config file, a simple forward for an action appears as

Subject: FW: Tomcat/Struts Profiling results


Hi,

For the last week and a half, a colleague and myself have been doing load/
scalability testing for our struts/jsp-based application. I would like to
share our results in the hopes that it may help someone else faced with a
similar task. We had a tough time finding real-world examples that we could
learn from. 

This is a LONG post, so I will try to summarize first:
==
Yeah..the summary is pretty long as well. 8-)

For JSP, tag-heavy applications, we found tuning parameters that may help
others get better performance out of tomcat.

We simulated a load of 50 concurrent users using automation tools that
remove any human pauses. This is roughly equivalent to 250+ concurrent,
human users. Yes...that is an estimation.

Initially, using Tomcat 4.0.1, Stuts 1.0 Final:

The IBM JDK performed MUCH MUCH better than Sun's Server Hotspot
JVM (1.3.1)

After profiling, we discovered that a significant amount of our time
was being spent in the garbage collector with the hotspot JVM. Some
of our garbage collections took a 12+ seconds! Ouch.

We attempted tweaking the various hotspot JVM parameters to see if we
could get the hotspot VM in line with IBM's performance. We did get
better results but we still had some GCs that were taking 6 seconds.

We had a large number of throw-away objects that were confusing the
garbage collector in hotspot.

We deployed the SAME EXACT application under Weblogic 6.1's servlet
engine, using the hotspot JVM, and we saw much better performance and
this was without any hotspot tuning parameters!

So we switched back to tomcat and we ran the application, using OptimizeIt
to profile the application. A majority of our time was being spent in
the constructor of BodyContentImpl because of an initial 8K char buffer
being created for EACH tag, embedded in our page. This was more pronounced
in our application because we iterated over content that had tags nested
in the iteratorthat's 8K X Number of iterations X number of nested
tags! We found that in our application most of our tags were only outputting
a few characters.

We recompiled the BodyContentImpl and changed the initial buffer size to
512 bytes. The results were dramatic and hotspot began outperforming the IBM
JDK. Keep in mind that the hotspot server VM takes a while to tune its
runtime
so was necessary to run our scalability test on the hotspot VM several
times.
I submitted an enhancement to bugzilla, its ID is 6858.

The final results were impressive!

Our application has one workflow that is VERY database intensive. It takes
a human user approximately two minutes to complete the workflow once they
are familiar with it. The transaction does 20-40 database selects with
result
sets in the range of 10-40 rows each (on average). 20+ Inserts when the
transaction is finally saved. All database activity happens in real time,
while
the user walks through our workflow.

Tomcat 4.0.1 + (our hack), using Hotspot Server JVM 1.3.1:

   Hardware: EJB server - PII 300 (-Xms64m -Xmx64m)
 Servlet/web server - PIII Dual 550 (-Xms128m -Xmx128m)
  
   Simulated 50 automated users (No human pauses) - Average transaction
speed
   21 seconds, longest time 27 seconds!
   
Of course this is our application...and each application will have its own
load characteristics, but it is a good example of struts + tomcat.

So..if our 50 automated users average 21 seconds and a human user takes
roughly 2 minutes for the same workflow then the above platform *SHOULD*
be able to support 6X the number of human users (300 users)

Thanks and I hope this information might be useful to others trying to get
a feel for how well JSP/struts will scale.

Do you use container managed authentication?
If so, where did you make this check?

My understanding is that the container will take control and send the user
directly to the login page with a new session in place (in the same way as a
new user login would).

The way we did it was checking an object (e.g. user) in session.  If it's
null, do
errors.add(ActionErrors.GLOBAL_ERROR, new
ActionError("session.timeout"));

(session.timeout is defined in your app resource properties)
thenreturn (mapping.findForward("logout"));

this logout fwd will then go back to the login page with the time out
message.

I have a struts web application which uses container managed authentication.

When a user is logged into the application and the session times out, the
next user-initiated action will result in the login page being displayed
(the j2ee container makes this happen).

How is it possible to tell that the reason that the user was directed to the
login page was because the session timed out and not because it was the
users first attempt at accessing the resource?

I would like to display message to the user indicating that the reason they
are in the login page is the result of a session timeout.

I am currently constrained to use of the Servlet 2.2/JSP 1.1 spec.

TIA,
Michelle

RE: null value for a nested property

David,

I find it's best to use a form bean that is different from your data
object, so that your get methods on your form object can return an empty
string if null instead of actually returning a null value.

I currently am using an  tag on a form to display the name of
a

The problem is that ocassionally the state field on the address bean is
null.  When this occurs the PropertyUtils.getNestedProperty() method

//This exception indicates that one of the nested properties
returned null
//we want to set the value to null and not throw the

I am wondering if there is a better way of dealing with this problem.  I
don't like the solution I am using, but I can't think of anything else.

What version of the Struts Validator are you using? 
Package names were changed at some point from
com.wintecinc.struts.* to
org.apache.struts.validator.* (1/14/2002).  When this
was done, most of the validator was moved to the
Jakarta Commons Validator
(http://jakarta.apache.org/commons).  I would double

Struts Validator NoClassDefFoundError

[Craig Raw]

Hi, 

I am using the Struts Validator in my webapp but encounter the following
error on each page that tries to use it.

java.lang.NoClassDefFoundError:
org/apache/struts/validator/action/ValidatorForm
at java.lang.ClassLoader.defineClass0(Native Method)
at java.lang.ClassLoader.defineClass(ClassLoader.java:509)


My WEB-INF/lib has the following jars
commons-beanutils.jar
commons-collections.jar
commons-digester.jar
jakarta-regexp-1.2.jar
struts.jar
struts-validator.jar
tiles.jar

The ValidatorForm is thus clearly in the webapp classpath.
I have read this may be because of the ValidatorForm class appearing
twice on my system classpath, but this does not seem to be the case. My
system classpath on JBoss is:

c:\Java\j2sdk1.4.0/lib/tools.jar
run.jar
../lib/crimson.jar
/C:/var/jboss/log/
/C:/var/jboss/lib/ext/activation.jar
/C:/var/jboss/lib/ext/castor-0.9.1.jar
/C:/var/jboss/lib/ext/gnu-regexp-1.0.8.jar
/C:/var/jboss/lib/ext/hsql.jar

/C:/var/jboss/lib/ext/idb.jar

/C:/var/jboss/tmp/

/C:/var/tomcat/lib/jasper.jar
/C:/var/tomcat/lib/servlet.jar
/C:/var/tomcat/lib/tools.jar
/C:/var/tomcat/lib/webserver.jar


The example war that came with the Validator seems to work fine, so it
must be a local issue to my deployment.

Any ideas?

Craig

yes that's true, try to check whether the web.xml file is well formed or not
as well as check if the web.xml is valid(i mean check against the DTD
mentioned on top of the web.xml file).

I ran into the same problem once, first time it was uri issue next time I
had the DTD part on top of web.xml wrong. 
hope that helps

I am not familiar with WLS5.1, but in WLS6.1 

if the web.xml file has the following taglib declaration 
 
/WEB-INF/struts-template.tld 
/WEB-INF/struts-template.tld 
   

it expects the struts-template.tld under the WEB-INF directory, check if you

have the struts-template.tld in the right directory.

RE: Populating complex java objects in forms

[Charlesworth, Chico]

The scope is request, which should be ok, and other form fields that are
Strings or String Arrays are populated ok, but not complex objects like
Customer.

Any other suggestions?

maybe check the scope of your form beans, maybe the one in the form is held
in the session, and the one your action is expection should be in the
request.
If that happens struts generates a new form bean which is empty.

Re: indexing of errors?

[David Winterfeldt]

Your property isn't really 'blah'.  It is 'blah[0]',
'blah[1]', etc.  So if you use the full property for a
field for the ActionErrors key, then you can retrieve
it next to each field.

ActionErrors errors = new ActionErrors();
errors.add("blah[0]", new ActionError("error.msg"));

 

This type of question would be a good question to ask
on the Struts User list.  And any development
suggestions are good to post to bugzilla if there
really is a feature request you want so they don't get
lost.

Populating complex java objects in forms

[Charlesworth, Chico]

Hi,

If I've got a complex java object (i.e Customer) in the Form class, I can
then read off this object in the jsp page, but when submitting to the Action
class the Customer object is null.

The jsp would look like:

Customer Name: 

Update Customer


So this would display the current customer name, but if I change the
customer name and then hit the submit link, I find the customer instance is

Re: nesting: iterate cannot find attrribute

[Elijah Jacobs]

Thanks for the responses guys - well appreciated

I found some insight in this:

it seems the error occurs only when I have a setter method to my Vector.
When I comment out the line below from my FormBean, the JSP page finds my
property just fine.

public void setX(Vector x) { this.x = x; }

I can't seem to find this in any documentation concerning this...does anyone
have further insight on why this is occuring?

RE: Design issue

[Ross MacCharles]

Since you are creating new pages for each OEM, I think I would prefer to
embed the OEM value in the pages themselves.  Then your 3 step process can
be replaced with just the 3rd step, and you don't need to restart your
container. 

If you do go with your approach, you may want to determine if the container
is smart enough to recognize the same servlet across multiple aliases.
Otherwise you are going to have unnecessary servlet instances. 

Seems like Tiles may fit in well here so you could possibly reuse some of
the pages across OEMs.

Subject:Design issue

Hi all,
I want to validate my design. 

One of our applications caters to 3 OEM's. Application has three business
functionalities and each business functionality has 4 to 5 screens on an
average. The only difference between OEM's is LOOK and FEEL of the
application. To achieve different LOOK and FEEL for OEM's, OEM names are
mapped to 3 different aliases ( OEM1, OEM2 and OEM3) of action servlet.
Mappings of OEM name and action servlet alias are stored in an xml mappings
file. When users belonging to a particular OEM access application for the
first time,  OEM name is retrieved depending up on the action servlet alias
and stored in a new session. Appropriate JSP's are processed depending up on
the OEM name stored in the session. 

There is no user authentication screen in the application. 

If a new OEM is added to the application, following steps are followed -
1. a new servlet alias is created
2. Create a mapping between OEM name and action servlet alias.
3. Create JSP pages for new OEM.

Any suggestions,

specifying dynamic value for logic:equal

[Srinivasarao Nandiwada]

Hi,

Let me briefly explain the problem  - I am using a select box in edit 
page and wanted to use simple text corresponding to the selected value 
in view page. My select box consists of the following :

Label One   ---> value 1
Label Two   ---> value 2
Label Three ---> value 3

I am using html:select and html:options in edit page and it works great. 
  However, my form bean only stores the value of the property, and in 
the view page, I need to convert the value of the property back to 
label. How do I do this without using scriptlets? I thought of using 
logic:iterate and logic:equal tags, but logic:equal tag requires a 
constant value which does not work for me as my select box is generated 
from the values from database. I thought of creating another property 
corresponding to label in form bean, but is there any better solution to 
this?

Thanks,

I suppose, if you ever wanted to goto XML at some point, you could just

In my FormBean I have:

I first set this attribute to some value in my action class.  In my jsp page

Cool ! This is on my list, so maybe we can collaborate ? I'd like to see
Chiki grow to use more than JSP for the Presentation Tier. So it becomes a
fuller example, running either Xml oro RDBMS, and JSP Velocity or Tiles (or
others). This is the kind of example which isnt really available at the
moment - the same app with simple config to change which
Presentation/Business tier it uses.

Looking at Velocity etc is on my list - but someway down at the moment ! So
it would be good to coordinate our efforts, saving on any duplication.

RE: design flaw if using a template...

[Ross MacCharles]

Hi Keith.


I look at the system as having several complementary models, controllers and
event triggers.  Struts Action, ActionForm, and submit triggers are among
them but not the only ones.  In other words, I don't see Struts Actions as
being the only system entities that can respond to event triggers, and
ActionForm beans are not the only data containers.  As you have discovered,
the struts objects are really only good at responding to a subset of the
possible events, and handling a subset of the pages data.  I think that is
intentional rather than a flaw.

If you buy that, then you can use "page load" as an event trigger, and your
own home grown "NewsModel" bean.  Some other home grown controller can go
get the data and push it into the news bean.  These homegrowns cause you
trouble when you try to force them to be children of Action and ActionForm.

So I'm suggesting only that the tag load and display the data from the news
model.  However, if you wish to have the "page load event" trigger a model
update, the lines get a bit blurry because I'm using the custom tag's
execution thread to kick off the model load, and refresh the display.
Although that thread is involved with "double duty"  the object model is
still clean --- the custom tag is just rendering data, and some other
controller logic is getting the data.

You could use other events to load the news bean such as user log in,
periodic polling, etc.  Not sure what your requirements are here but I'm
guessing you want the news updated on each page load.

OK I'll shut up with the philosophical stuff and let you get back to the
real solution that Matt helped you with :)

Good Luck

/Ross

Hi Ross

Good comments.

You see, with custom tags, there are several problems:
- For each different parts of the template, I need to create a custom tag
- This custom tag is actually what an xxxAction class is meant to do, ie
retrieve data from a database and prepare the data for view
- If I later decide not to put news in the template and put it in a separete
page, I need to port the taglib code to an xxxAction class. Not very
flexible.
- taglibs from Struts point of view, only renders data for viewing. It
should not be performing model work, which should really be in the xxxAction
class.

So, I can see that Struts was designed to handle "user invoked" actions, not
"code invoked" actions.

Any more thoughts?
Keith

Consider rethinking the philosophy that all data rendered in the JSP must
come from an ActionForm.   In my mind the ActionForm generally represents
the editable data for the page displayed to the user.  There's no problem
with displaying data from other sources on the same page - especially read
only data.

For news I would simply use a custom tag to get it and display it.

Put another way, I wouldn't want to have to set up a bean with "setNews" and
"setMemberCount" when I have no intention of allowing my application to edit
those values.

Hi

Struts provides us with a nice MVC architecture, where:
- a user's click maps to an Action
- based on the results, the user is forwarded to the view

Now, I have a template.jsp which all pages will use. The template will
contain some views that are common to all pages, eg:
- Latest News
- Site visits
- Member count

To retrieve these information, it gets them from the database. However,
there is no user click to invoke the action. This is where the limitation of
Struts comes in. Let me explain:

In the template.jsp, we can have:



In news.jsp we can access the database and retrieve the news for display.
This breaks the MVC pattern, since the view is accessing the model.
Alternatively, we have have this in the template.jsp:



This will call the NewsAction which accesses the database, and forwards the
results to the news.jsp for display.

This is a great concept, but it does not work. Struts does not allow
multiple forwards (this happens when the current page is already a .do).
Here's an example:
(1) User clicks on viewUserDetail.do
(2) ViewDetialAction forwards to user.jsp
(3) In template.jsp (used by user.jsp), news.do invokes NewsAction, and it
forwards to news.jsp

This is a double forward, which results in an exception.

Basically, I want to call



in the JSP. Has anyone done something like this?

RE: "Best Practice" for parsing an XML file - Code Review Requested

[Matt Raible]

Good idea.  What I'm trying to get away from is that user's (sys admins) have
to edit the web.xml file.  This is because I plan on distributing my
application as a WAR, and need to I have certain parameters that WILL need to
be changed for different systems (i.e. Unix vs. Windows).  Also my web.xml is
already pretty huge, so digging through it to edit parameters might be tought. 
And it'll get overwritten everytime a new version is distributed.

That is why I look it up in System.getProperty("user.home") and then /WEB-INF/.

Maybe a bad idea, but everytime I move my app to my OS X box, I have to change
the parameters in the config file.  If I lookup user.home, then I alleviate
this problem.  However, when the app is first installed, it won't be in
user.home, so I look in /WEB-INF/.

Thanks for your help,

On this note, has anyone used McKoi ? (http://mckoi.com) Its an Open Source Java SQL 
Database System that I've just started looking at, and it looks very promising. 
Wondered if anyone else had come across it.

In the context of Struts apps, it allows you to bundle the db with your app, great for 
apps like Chiki that need to run out of the box without requiring users to setup any 
external 3rd party stuff.

Let me know if you have experience with McKoi. I intend to upgrade Chiki to use McKoi 
and I'll knock together a little tutorial on using McKoi with Struts apps, if anyones

Cool ! This is on my list, so maybe we can collaborate ? I'd like to see Chiki grow to 
use more than JSP for the Presentation Tier. So it becomes a fuller example, running 
either Xml oro RDBMS, and JSP Velocity or Tiles (or others). This is the kind of 
example which isnt really available at the moment - the same app with simple config to 
change which Presentation/Business tier it uses.

Looking at Velocity etc is on my list - but someway down at the moment ! So it would 
be good to coordinate our efforts, saving on any duplication.

Absolutely. I'll look forward to speaking with you more.

Ghoot,
Looking into Chiki is on my to do list. I just didn't get around 
to do it yet (have browsed your site extensively but not looked 
at the implementation)
In any case, for a Struts forum I think it would be nice to use
Struts technolgoy even if Chiki misses some features of other Wikis 
at the moment. I'm sure this will change soon :-)

As you might know, I am working on the Struts/Velocity integration.
My personal interest in Chiki is to find out how easily it could be
turned into a show case for Struts/Velocity. 

In any case, I'll report back once I have had a chance to spend some
more time with Chiki.

I certainly would voluteer to help with setting up and maintaining
a Chiki-based Struts Know How forum. My experience is that like a
nice garden, such a forum needs a few gardeners that are devoted
to its well being.

Re: how to edit an array of records with action forms?

[Arron Bates]

Nightly build version can use implementations of the java.util.List 
rather than having to get back the primitive array object. Makes things 
easier to work with.

Returning the Object[] actually renders everything but ArrayList style 
collections useless because the mapped collections and such don't know 
how to update from an index. Returning the array from an ArrayList 
itself isn't that big a hit, as it's backed by such an array anyways.

Arron.

Re: how to edit an array of records with action forms?

[Ian Tomey]

ahh, just paid more attention to your example code :-) 

  
public BunchBean() {
  this.bananaList = new ArrayList();
  this.bananaList.add(new BananaBean());
  this.bananaList.add(new BananaBean());
  this.bananaList.add(new BananaBean());
}
 
public Object[] getBananaList() {
  return this.bananaList.toArray();
}


could this potentially be a bit of a performance killer ( the .toArray() ) stuff with 
some collection types?

Who's fixing the number of records?... The tags will happily do whatever 
with what they're given. The monkey example adds and deletes objects in 
the various lists with ease.

You could even map the bean properties to access columns in a result 
set. Wouldn't be on the "best practice" list however :)

form/multipart

[Torgeir Veimo]

I am having trouble with a form that contains both a file upload button 
and some other button.

There is one input field which is used to create a new file, and a 
submit button for that. There is also a file upload button, and a submit 
button for that.



 <%-- create a new file --%>
 
 

 <%-- upload a file --%>
 
 



Upload of file works ok. The trouble I'm having is that if I want to 
create a new file, by entering a filename and selecting the new_document 
submit action, I get an exception.

It works if I select a file to upload, yet still selects "new_document".

Is there a way around this?

Here the exception I get

RE: Application Scope Variables

[keithBacon]

Application Scope - Generally, application scope beans are initialized in the
init() method of a startup servlet. However, it is legal for an
Action class to create such beans, if this is appropriate, like this:

Foo foo = ... create a Foo ...;
servlet.getServletContext().setAttribute("foo", foo);

Enterprise Object Broker (EOB) is an application server that tries to a

  * Real Java interfaces & impls (no XxxHome or XxxRemote interfaces) .
  * Does not use RMI for interoperation (no RemoteException, no 
extending rmi.Remote interface).
  - Uses AltRMI (commons-sandbox).
  * No forced choices about persistence.
  - Use files, Castor, XML, JDBC, delegated, whatever..
  * Avalon Framework methods ( IoC pattern )
  - Beans are handed a ServiceManager they use to lookup() other 
beans without have multiple
  lines of JNDI code.
  * Applications can hand a WAR file to Hendrik Schreiber's Jo! 
webserver (same VM) for web publishing.
  * Sits on top of Avalon-Phoenix.
  - Meaning it could be along side (and the beans could use) 
multiple other server components.

Supplied Examples:

  0 - Dual impl stock-quote service with ugly WAR file web-presence.
  1 - Small People & Addresses PIM. Beans in different jars, and 
potentially machines.
  2 - Small shopping cart app. Beans all in one jar.
  3 - A port of Velocity's ForumDemo app.  The obj model moved to EOB, 
Jo! handling WAR file.

For those interested in the EOB project, ignore the 0.20 release as it 
does not have the ForumDemo in it.  If you are CVS and Ant savvy, you 
should manage to build and launch the demo.

We are looking to add more demos, especially Jakarta ones.  The best 
candidates are WAR file apps with object models (hopefully 
interface/impl separated) that can be moved out of the Servlet's 
context.  These also include EJB using webapps, but the EJB side would 
have to be trimmed of the EJB 'noise' before being run in EOB.

As well as our need for more demos, we are interested in people to join 
in the main development.  Apache license of course.

Re: how to edit an array of records with action forms?

[Ian Tomey]

Hi Arron,

Had a quick look at it, seems like what I need. One gotcha though is that the number 
of records is not fixed, so the creation of the array of row objects in the form 
constructor has to be bigger than the max size expected. I'm hoping that 
actionForm.reset is called before bean population then I can init the size of the 
array from looking up the param. ugh, an ugly kludge.

good work BTW.

Cheers
Ian

If you're on a nightly build, you'll have the nested extension already 
there. It will help you make light work of iterating objects.

For a pimer and tutorial, go here...
http://www.keyboardmonkey.com/struts 

And for mor implementation detail for each of the tags, the Struts site 
has the most complete info.

Arron.

RE: "Best Practice" for parsing an XML file - Code Review Requested

[CARDON Denis]

Hi Matt,

I agree with Emaho, xml is (much) better for describing data. 
As for the parsing, I totally agree with you, using DOM is a pain
that one should avoid as much as possible. In your case you 
may use a more user friendly API such as Dom4j or jDom.

If you have some time to spend, you may even try to learn 
about XML schema and use Castor (castor.exolab.org) to create
a XML to bean mapping, then reading your config file will be
as easy as getting property from a bean. Example bellow : 


  
url0
driver0
login0
password0
  


then reading this file will be as easy as : 

//starting here!
Reader input = new FileReader("c:/configFile.xml");
ConfigFile config = ConfigFile.unmarshal(input);
DatabaseConnection db = config.getDataBaseConnection();
String url = db.getUrl();
String driver = db.getDriver();
String login = db.getLogin();
String password = db.getPassword();
//that's it!

Moreover it will tell you if your config file is not valid
(for example if you mis-spelled one element).

The only tricky part is to create the XML schema. You may 
use Xml Spy, it has a very intuitive schema editor (it has
an evaluation version). Once you have get used to it, 
doing all this should be a matter of minutes.

Hope this help

Denis

Re: problems with doing a Titles Invoice example

[Cedric Dumoulin]

  Hello,

  It is a problem with custom tags implementing "BodyTag" interface in jsp 1.1 : it
is not possible to do a flush inside such tag.
  In your example,  (or  ?) implement BodyTag, and
 do an include which automatically do a flush (even if you
specify flush="false").

  Your construct should be possible with jsp1.2 (try with Tomcat4), but I think
that  need to be reimplemented to use new Tag support.
  A workaround is to write the iterate loop as a scriptlet ;-(

Re: Multiple submit buttons solution

[keithBacon]

You're right peter.
Come on the old struts pro's - do we need this or not?
I don't know enough to judge.
for - good to have choiice of using link or button.
against - you can do it with a link so why add more fiddly functionality
