All,
What is your experience with the Web server you are currently using to run
Struts? Does it handle pages with a large number of tags well? Have you
had to discard a certain server because of a problem in favor of another?
Any comments appreciated...
Thanks,
Brian

Pete was right.. I needed to specify. I'm looking for high-end, high-load.
1 million hits a day on a server that implements a lot of JSP tags.
Somehow I don't think Tomcat's going to do that (nor do I think my
management is going to like using a server that doesn't have technical
support :).
Let me try to venture a few responses...
But my beans already contain the validation! Besides, performing the
validation in the ActionForm is effectively tying business logic (data
validation) to the web framework dontya think?
Well, I put data type and required field validation only in the
Yuriy,
Yep, you have my interest.. Are you using multiple sets with different
Comparators (based on bean properties) to do that?
Thanks,

Martin,
I need to perform a submit in order for the server to see the new value
that the user entered on the form in order to add it to the bean.
html:link won't do that for me...

Try under Tomcat 3.2.3. Otherwise, if you really want to get it to run
under Tomcat 4, research some of the older messages in this archive (you
need to replace the xml parsing jar files which come with Tomcat 4.
All,
I have a page with a control which allows the user to add items to a vector
on a bean. Basically it is a company form with an Add Subsidiary button.
Each time the user presses Add, the vector on the company formbean
receives the new element. However, when the page reloads, I want the

Here's Craig McClanahan's message from a while back which I think addresses
your problem:
I build Struts on both Linux and Windows. Here is what I did:

Kat,
Use:
bean:define id=NameOfPageScopeVariableToDefine name=BeanName property
=PropertyNameOnBean/
someLibrary:someControl selected=%

In this example, the variable is defaulting to page scope. I would not
define the variable as session scope since
Will,
If the [style] tag is still failing, you probably still need
jakarta-ant-1.3-optional.jar in the lib directory of ANT.

Maybe these versions don't play well?
It is possible that the jar files that come from Tomcat might not be
compatible. You still need to get JAXP 1.1 from the Sun Web site at:
http://java.sun.com/xml/download.html (I did not have any trouble). Also,
it is not necessary to place the XML
Actually, struts-bean.tld has a define tag which does the same thing (no
custom eval tag necessary):
bean:define id=idValue name=somebean property=id/
html:link href=somepage.jsp?action=someactionid=%= idValue % link
text/html:link
Alex,
First, I definitely would not use a nightly build for a major demo since I
have found them to be somewhat buggy in certain areas. Our development
efforts are based solely on the 1.0 release which I augment with new
tested functionality on an on-going basis (only as an extension layer).
The server is doing that, not the messenger. I had that happen to one of
my previous messages also...

Richard,
I can think of 2 things that may cause the data structure to not persist.
1. The framework might be calling an implemented reset() method on your
formbean. To get multi-page formbeans to work, I had to avoid
implementation of this method (since it is called between requests). 2.

William,
The action does not directly know the next view or previous view. The
action object returns a generic ActionForward object with a success,
failure, etc. or a more specific contacts, roles, etc if you have
sub-screens with that information. The controller uses struts-config.xml

This is a follow-up to my Wizard question...

pages by a template, then what is the best way to make sure information is
stored between requests for the different pages? Even though all three

My link is:

=index.createStakeholder//html:link
it works, but the URL shows:
http://localhost:8080/dne-struts/createStakeholder.do?action=create
no jsessionid :(
Any hints appreciated!
Thanks,

Here's my
To follow up my last message:
jsessionid is now being passed from index.jsp to my next form:
CreateStakeholder.jsp. CreateStakeholder.jsp does not seem to recognize
jsessionid when it is sent, and does not re-write the link tags.
RequestUtils is using introspection on your form bean class to match the
name you placed in your html:text tag with a bean method name. So, if you
had:
html:text property=requestDate
Your form bean should have: String getRequestDate()
andvoid setRequestDate(String)
You're Bean class does not extend ActionForm..

Marcel,
I walked through code example submitted by Warwick Boote to get past
issues/concepts with setters for indexed properties. The only change I
made was to add a second field to the form. So, if your list is named
properties, you would have second field on the form called property also.
Did you try html:base/?

I have 2 questions:

Is it possible to use the iteration tag to go through the list and
provide a break between the items?

Try 2 things:
1. Remove any XML parsers from your classpath. A pre-existing xml parser
in your classpath may supercede the XML parser which comes with struts.
Struts will not work with just any XML parser...

All,
I have been doing a lot of research into Struts recently. My question is
about performance and scalability. First the definitions:
Performance = good response time to users
Scalability = good response time to a large number of simultaneous users.
Usually this is a logarithmic curve
Jon,
That did something. Before when I was starting my server, the console
read:
-
Starting service Tomcat-Standalone
Apache Tomcat/4.0-b6
Starting service Tomcat-Apache
Apache Tomcat/4.0-b6
Jon,
When you posted the version of the xerces compiler you were using ***xerces
1.3.1***, that solved my problem.
Here's the link guys:
http://xml.apache.org/dist/xerces-j/
Get xerces1.3.1.zip from the link above and do like Jon said in his
original message. Remove the other XML parsers
Jon,
I received that same error after I removed catalina.jar, but didn't have
xerces.jar in the classpath.

Has anyone with iPlanet Webserver 4.x, 6.x been able to get Struts to work?
If so, have you run into the:

org.apache.struts.action.MESSAGE error?
If so, how were you able to fix it?
Thanks,

Dave,
It sounds like you may be having a problem with holding onto the session
between your two frames. If this is a possibility, then set a session
variable in the lower frame and try printing out your session information
in the top frame to see what is going on.
Brian
Renzo, Felix,
If your front-end web server/load balancer (also known as Local Director or
Resonate, etc) is implemented to use IP stickiness, then this is a
non-issue since the Web user will be returned to the server which serviced
the original request.
