Re: Struts user base

[Jannik Nørgaard Steen]

Hi,

we are a danish company in the Media Asset Management business. We are
developing our web-interface and have based it entirely on Struts.
We are using Borland App Server 4.5 as EJB-backend, with Apache and Resin on
the side.

need to restart tomcat after modifications in (formbean || action class)

[gustav spellauge]

i just discovered struts and am experimenting a bit.

i discovered that i have to restart tomcat (3.2) after i modified either
of the formbean or action class.

javax.servlet.ServletException:
org.apache.struts.util.PropertyMessageResources
 at
org.apache.jasper.runtime.PageContextImpl.handlePageException(PageContextImpl.java:459)

also i have to restart tomcat after modifications in
ApplicationResources.properties

is there any way to avoid this restart.

thanks in advance

In wich way do I have to set the struts configuration file?

Thanks for any idea

RE: struts:example

[Mark Davidson]

Did I miss a configuration step somewhere?

Wait a second... earlier today, I e-mailed the list with a similar problem
(I couldn't get the Struts' examples to work).  The struts-example wouldn't
work under Resin or Tomcat because it couldn't find the
org.apache.struts.example.User class.  It also couldn't find the properties
file for the application (in the same directory).

So, I did discover that if you let Tomcat unpack the .war file, stop Tomcat,
edit your classpath to include the classes directory that just got unpacked
and then restart Tomcat, the problems go away.

My question to the list is... WHY?  It's *can't* be that you're supposed to
do things this way.  I must have missed a configuration step, but for the
life of me, I can't see it.  I find it difficult to believe that you have to
point your CLASSPATH to the unpacked .war file in order to get Struts to
work.

If someone can tell me the *right* way to do this, I'd greatly appreciate
it!

These are the classes used by the struts example.So you should include these
classes in your classpath.For ex. If this class file is within the
web-inf/classes directory then include int web-inf/classes directory in the
classpath before starting the server.It works perfectly with the tomcat server.

[OT] Web-initiated restarts for Tomcat 3.2.1?

[Nathan Eric Probst]

Hello,

I'm attempting to setup a shared development server to use with a
distributed developement team.  (All two of us!)

I want to allow my partner, who is doing the page design, graphics, and
JSP to "bounce" Tomcat remotely WITHOUT giving him an account on my
machine.

I've already written a simple buildServlet that updates the local copy
of our CVS project and builds it to the context directory
(webapps/our_project/).  I've added the admin/reload.do Action to catch
config changes.  I've set the reloadable='true' in server.xml for the
Context.  Now I need to provide the ability to "bounce" Tomcat, just in
case it reloads funny.

Does anyone know of a reliable way to do this?

I've written a simple bounceServlet that uses Runtime.exec() to call a
bounce.sh script (I'm running Linux) that does a 'tomcat -stop' and
'tomcat -start'.  The problem is that it work *sometimes*.  There is a
race between the call to 'tomcat -stop' and 'tomcat -start'.  At least,
that's my explaination.

So, does anyone have a better solution?

Nathan

RE: Problems Converting from .5 to 1.0

[Stefan Winz]

Yes, i had a similar problem for an action link that populates the instance
variables off a form from beans stored in the session.  I was using the name
attribute in the action mapping so that it would save the name of the form
that it set up.

I didn't really investigate, but I assume that the action assumes that this
form already exists by the time it gets to action.perform().

I made the name of the setup form a property off the Action instead and
removed the name attribute altogether.  That worked.

Hope this helps.

Struts example doesn't work???

[Mark Davidson]

I've seen other people post about this problem, but I really haven't seen a
good answer to why this problem is occurring... I'm hoping someone can
enlighten this poor soul as to what's going on.

I've downloaded the Struts nightly binary build (I've actually tried
several; all do this), and placed the struts.jar file in Tomcat's tree (as
per the instructions).   I've also placed the .war files in the webapps
directory.  Tomcat gets started, sees the .war files and proceeds to unpack
everything.

Problem is... the example app doesn't work.  If you try to go to
http://localhost:8080/struts-example, the system proceeds to do whatever it
needs to do to compile the JSP pages, then throws an error 500:  

Location: /struts-example/index.jsp
Internal Servlet Error:

javax.servlet.ServletException: Missing message for key index.title

l.java:459)
at
_0002findex_0002ejspindex_jsp_2._jspService(_0002findex_0002ejspindex_jsp_2.
java:381)

... the rest of the trace is removed to keep this message small.

>From looking at the code, it seems that the code is having problems loading
the ApplicationResources.properties file (where the text for index.title
is).  The file is definitely there, in the org.apache.struts.example tree.

I've seen other postings from people using both Tomcat and Weblogic, and
having the same problem.  My question is... why?  I know some people have
suggested unpacking the war file and struts.jar file so they can be in your
classpath, but I would love to know the reason behind this issue.

Any ideas or suggestions would be greatly appreciated.

how to determine size of collections using tags

[Deadman, Hal]

Is there a way to determine the size of a collection that one might iterate
over using struts tags rather than a scriptlet? I often want to display one
thing if the collection is empty or I want to iterate over the collection.
The only thing I can think of involves adding a get method to the JavaBean
containing the collection that returns the collection size . That would let
me use the logic:equal tag to check the property. Is there a non-scriptlet
way to do this without adding a method to the JavaBean?

 Well, I did get this working but with a couple of major caveats. 

1) In order to define a given , I had to use scriptlets for all
the code between the start and end tag. I assume this is because - from
what someone enlightened me earlier with - you can't nest tags. I hope
I'm wrong about this because it significantly clutters up the JSP and 
renders all the bean tags unusable. =:|

2) I needed to locate the hypertext index at the bottom of the document
because the index dimensions are determined as the results are iterated. I
assume this could be fixed by buffering the output to a StringBuffer or
somesuch but havn't tried that yet.


If anyone has some usage suggestions for this pager taglib, I'd
appreciate your input.

 Actually, I can run the example that comes with the distribution but am
having some problems using this pager taglib in Struts. The links created
by the pager aren't working.

 The example I'm working on has a JSP with an embedded form that, upon
submission, invokes a database query and reads back the results stored in
request scope beans (to the same JSP). The pager creates the correct
number of links to result pages. For example, one link created is:

http://localhost/project/simpleQuery.jsp?pager.offset=1

But when I click on this link I only get my simple query form and the
pager output of:

Yes ... it does mean "internationalization".  The "18" in the middle is
sort of a pun on the fact that there are 18 letters between the initial
"i" and the final "n".

Likewise, l10n (the initial character is an "L") means "localization".

Last Call for Struts 1.0 Bugs

[Craig R. McClanahan]

The few remaining Struts bug reports are feeling kind of lonely.  Do you
have any more bugs that you would like to see fixed before Struts 1.0 is
released?  If so, please post them to the bug tracking system at:

http://nagoya.apache.org/bugzilla/

under product "Struts".  Even if the bug has been reported to a Struts
mailing list, this is the best way to ensure that your bug does not get
missed in the final rush towards release.

Feature requests are welcome as well, of course, but the focus right at
the moment is on identifying and squashing any remaining bugs so that
1.0 comes out of the box as an extremely solid platform for building web
applications.

I think, the original struts-example has a multiple rows form for "Current

Unfortunately, this solution is not going to help unless you much -- at least in a 
servlet container that conforms to the spec requirements.

ServletContext.getResource() returns you a URL of a web application resource -- in 
other words, of a "file" or "directory" entry from the original WAR file.  For 
example, you can get a URL to read the web.xml file itself, if you want to, by calling:

URL url =
  getServletContext().getResource("/WEB-INF/web.xml");

However, the internal copy of the DTD we are talking about here is in the struts.jar 
file (along with all the LocalStrings.properties files containing messages generated 
by the Struts components themselves).  Struts expects to be able to access these 
resources via the class loader that the class was loaded from.

URL url =
   
this.getClass().getResource("/org/apache/struts/resources/struts-config_1_0.dtd");

Among other things, that means the call will succeeed whether you leave the Struts 
classes packaged in "struts.jar", or unpack them into WEB-INF/classes -- it is totally 
up to the class loader to figure out how to return a URL that can be used to read 
these resources.  And the class loader in question is the class loader provided by 
your servlet container.

input form with indexed properties

[Shamdasani Nimmi-ANS004]

Hi,

Is any solution to handling an input form with data in a table form (i.e. multiple 
rows of same kind of data) on Struts horizon in the near future? 

Also If anyone has worked with such a form and have an example to share I will really 
appreciate it. Thanks

Enhydra: Re: DTD validation of struts-config.xml

[DONNIE HALE]

To those interested:

I followed the rabbit trail implied by Craig's response, and have discovered that in 
fact there is an issue when Struts attempts to register its local DTD in the 
initDigester method. However, I believe it may be due to a bug in the Struts code, not 
Enhydra's class loader. The class loader implicitly used by the code in 
ActionServlet.initDigester:

URL url = this.getClass().getResource(registrations[i+1]);

is "org.apache.tomcat.core.ServletClassLoader". I didn't pursue this angle terribly 
far other than to intuit that it wasn't the class loader I expected.

Making a short story long, I figured that the "getResource" method on the servlet 
context was the appropriate method to use, I changed the relevant section in 
initDigester to:

// Register our local copy of the DTDs that we can find
for (int i = 0; i < registrations.length; i += 2) {
URL url;
try {
url = 
getServletConfig().getServletContext().getResource(registrations[i+1]);
}
catch (java.net.MalformedURLException e) {
url = null;
}
if (url != null)
digester.register(registrations[i], url.toString());
}

This seems to fix the problem, though I can't say for sure what ill side effects it 
could have. My guess is that one can't assume that the class loader of the servlet 
class itself (at least, perhaps, while it's "init" method is still running) is the 
same as that of the web application as a whole. Consequently, the standard servlet 
getResource method is appropriate because the classpath of the class loader being used 
behind the scenes of that method is the one to which the WEB-INF/lib stuff and 
WEB-INF/classes directories have been added.

Thanks,

Donnie

As you can see from the source code in ActionServlet, Struts attempts to
register its local copy of the DTD in the initDigester() method.  It
uses Class.getResource() to actually acquire a URL for reading the
contents of the DTD, which is stored as a resource in the "struts.jar"
file.  If the web application class loader in Enhydra has problems
implementing this method correctly, you could encounter the symptom that
you report (trying to go across the network to grab the DTD).

template-example and i18n

[magnus . sirvio]

Hi,

I thought it would be nice to use the template-example technique with the i18n 
support in struts but is running into problem.

Below is a code snippet for the entry to the web I\'m building - slightly 
modified from the template-example example.


<%@ page language=\"java\" %>
<%@ taglib uri=\"/WEB-INF/struts-bean.tld\" prefix=\"bean\" %>
<%@ taglib uri=\"/WEB-INF/struts-html.tld\" prefix=\"html\" %>
<%@ taglib uri=\"/WEB-INF/struts-logic.tld\" prefix=\"logic\" %>
<%@ taglib uri=\'/WEB-INF/struts-template.tld\' prefix=\'template\' %>


  
  
  
  
  


Instead of using the Name \'Template\' of the page I thought it would be nice to 
look up this value using the  tag. How shall one do this? I have, 
newbie as I\'m to jsp and tag libraries, tried
  template:put name=\'title\' content= 
direct=\'true\'/>
and some variants without fortune. Please help me...

As you can see from the source code in ActionServlet, Struts attempts to
register its local copy of the DTD in the initDigester() method.  It
uses Class.getResource() to actually acquire a URL for reading the
contents of the DTD, which is stored as a resource in the "struts.jar"
file.  If the web application class loader in Enhydra has problems
implementing this method correctly, you could encounter the symptom that

The application's message resource bundles are shared across all of the users of a
particular Struts-based web application.  The only thing that is unique to a
particular user is the java.util.Locale object (stored in the user's session) that
represents his or her current Locale preferences.

It is pretty hard to know for sure on an open source project, but the subscriber count

I would do exactly the same thing in your shoes.

I'm biased (being the primary author), but from what I have seen so far the bug list 
is small primarily because of stability.  One of the huge benefits of open source 
development is "distributed debugging" (lots of eyes looking at the code and trying 
things out).  In the eight months since Struts was started, there
have been *lots* of bug reports (and associated fixes) resulting from this.

>
> 2. Are there any European users?

A perusal of the mailing list archives indicates that interest in Europe is quite high 
-- I imagine a lot of this is because of the fact that Struts promotes i18n as a first 
class notion, instead of something you bolt on later.

>
> 3. Does anyone run Struts on commercial servers, e.g. BEA's Weblogic?

Yes, there are Struts users on Weblogic and many other server platforms -- the 
installation docs in the Struts nightly builds have been recently enhanced to include 
notes about the experience of using Struts in such environments.

One thing that has been quite interesting (to me) is that Struts is often used as a 
"servlet/JSP compatibility" test by its users, and has triggered service pack updates 
on quite a few server platforms to improve their conformance to the servlet and JSP 
specs :-).

We haven't tried to define a release time frame after 1.0 yet, but here's what I 
envision:
* Bug fix updates (1.0.x) will happen as often as needed to deal
  with any bugs that are found after 1.0 is released.
* The timeframe for 1.1 depends on how many developers volunteer
  to help out (the current 1.1 TODO list is in the documentation bundle).
  As significant features get completed, there will be a vote on the
  developer list to release updates with new functionality -- I would imagine
  this would happen at least every six months, or faster if more people
  are willing to participate.
* To the maximum degree feasible, applications should be able to
  depend on APIs and functionality throughout the 1.x family of
  releases.

The details vary by container, but generally the entire webapp is running

It's not whether they are stable or not that matters, it is whether they
implement Serializable or not.  On some containers, such as Tomcat 4.0,
sessions and their Serializable attributes *are* saved across webapp restarts.

This is not universally true.  For example, Tomcat 4.0 has the ability to
save and restore your sessions across a server restart or automatic reload
-- as long as your session attributes are Serializable, they will also be
restored.

Many other servlet containers offer similar capabilities -- check your
container's documentation for the details.

DTD validation of struts-config.xml

[Lee Hall]

We've been using the Tomcat 3.2 that is integrated with NetBeans to do our Struts development.  Our test deployment server (AIX 4.3 with the IBM 1.2.2 JVM) is running a vanilla Tomcat3.2.1.  Neither of these environments has any problem with the subject of this message.
 
Our pre-production server (AIX 4.3 with the IBM 1.2.2 JVM) is running Enhydra 3.1 and fails initialization due to the validation done by ActionServlet.  We've tried forcing Xerces 1.2 in Enhydra, but Enhydra persists in it's attempt to validate using the network URL instead of the local resource.
 
I hacked ActionServlet.initDigester() to turn off validation and that got us by - but I know it's the wrong way to deal with this.  In spite of the Barracuda project, I would hope that the Enhydra team would want to be completely Tomcat-compatible (which I think includes Struts compatibility).  Still, it was easier to "fix" the ActionServlet than to fingure out why we are having this problem with Enhydra.  I know, I know... I should have extended ActionServlet to override instead of butchering my clean Struts - but the question remains regarding why this seeming incompatibility exists.
 
Could somebody give me a clue?

 Very handy! For anyone else looking at this for paging long-winded

"pager-demo.jsp" and change:

This fixes a hack put in to convert "20" to an int as delineated in the

The property accessor syntax in Struts 1.0 supports only constants as
array subscripts.

You might consider using some sort of runtime expression instead, to
dynamically calculate the property to be retrieved.  Assume that "i" is
an integer variable, and you are inside a loop:

The challenge with doing this is that the JSP tags run on the server (as the page is 
being generated), while the JavaScript runs on the client side.  To integrate the two, 
you need your tags (and other JSP code) to dynamically generate the JavaScript 
functions themselves -- sort of having a program write a program --
so that the JavaScript is customized to your particular need on this particular page.

A very trivial example is the way that the  tag deals with the "focus" 
attribute.  If you specify it, a dynamically generated bit of JavaScript is created to 
set the input focus, which includes the name of the field you want initial focus 
assigned to.

For a more comprehensive scenario, consider that for most menuing systems you will 
need to configure the list of available options into a JavaScript array or something.  
You could use the  tag to render the elements that get set in the 
array's initialization expression.

Re: Struts user base

[Ted Husted]

You probably want to spend some time in the mail archives. 

The Struts-User archive at < http://mail-archive.com > is my personal
favorite. 

It was recently mentioned that there are over 900 subscribers to the
mailing lists. 

Jakarta projects offer nightly builds with the latest fixes. 

How often formal releases happen depend on how many people contribute. 

Your team, for example, could offer patches and improvements to the
code, and eventually become Committers. You could then help decide when
and how many of these things happen. 

Struts is standards-based, and works with most containers. WebLogic 5.1
with sp8 is fine, and WegLogic 6 is suppose to a no-brainer.

Localisation

[Sebastien Cesbron]

I have a simple question about localisation :

If there is multiple users using the same localisation parameters : do
they share a common ResourceBundle instance or do they have their own
one.
It seems to me that each user has his own ResourceBundle instance but
does that affect the performance of the application.

Thanks in advance

Re: Struts user base

[Burr Sutter]

Christoph,

Are you both a SilverStream and Struts user?
Do you have a documented list of steps to implement Struts on a SilverStream
3.7 server?
I was going to put together a document like this but I've not had the time.
I'm aware of the SilverBooks37 example but I've not seen any documentation
on how to enable Struts in your own WAR.  I just taught the J2EE course on
3.7 and wanted to demo the steps involved but didn't figure it out quickly
enough.

Any help is appreciated!
How are things for SilverStream in Europe?

for the commercial servers part : 

Struts runs on SilverStream without any problems. I think the other ones

I really should have said "final release testing". 

In practice, the current releases are being actively beta-tested by
hundreds of developers every day.

I believe Craig has said that if it doesn't come out this quarter, he

I'm aware that there are several very large projects in the work. Struts
was "born" less than a year ago, and so there hasn't been time to
develop anything truly huge. Check here for a "Powered by Struts" list

How stable is struts?

[Mark McLaren]

Hi,

I like a lot of the functionality of Struts and am considering using struts
as a framwork for a very large commercial e-commerce site.  However, I have
reservations about using alpha code.  My questions are:

1.  How buggy is the code?  Have many developers found that they spent much
of their time trawling through the struts source code to fix a bug rather
than developing application-specific code?

2.  When will version 1.0 be released?  I'm not looking for a binding
commitment, just an estimate (e.g. Next month? Next quarter? Next year?)

3.  Are there any large commercial sites that currently use struts?

Many thanks

Mark

Re: Sessions lost when server restart or class reload

[ARTUSD]

 When a class is reloaded because you have change it the objects saved
on
 sessions are lost and all the users connected to that application
suffer
 that.

Do all classes get reloaded or only those that have changed?

If all objects in sessions are stable types (e.g. Strings or name/value
Collections) do we dodge the
problem?

Well, I'm happy enough with Emacs in general, but I've not yet managed to get a
nice JSP editing mode going. I've tried without success to get the multi-mode
thing going, are there any other suggestions (I develop on Linux - the Java
