Latest and Greatest 1.0 User's Guide

[Craig R. McClanahan]

I've just posted the most recent version of the Struts documentation on the
Struts web site at:

http://jakarta.apache.org/struts/

The User's Guide pages have had the XSLT stylesheet used to create them spruced
up a bit, so that the visual appearance is similar to the rest of the Struts
documentation.

Of the objects related to the framework itself, I would make the following
suggestions:

* Struts supports form beans in either request scope or session
  scope.  If your form is all on one page, and the bean has properties
  for every form field, request scope avoids having the form beans
  hang around in memory between requests (but, on the other hand,
  this requires Struts to create a new one on each form submit).

* For form beans (or application beans in general) that you store in
  the user's session, be sure to clean up after yourself by calling
  session.removeAttribute() when you no longer need a bean.

The remaining objects in the Struts framework are either created once and
shared, or managed for you automatically.

RE: javax.servlet.ServletException when running struts-example on JRun 3.0 / NT 4.0 SP5

[Abraham Kang]

I got it working with JRun but is
D:\JRun30\servers\default\scb\WEB-INF\classes part of the struts example you
are trying to run.  I don't think
D:\JRun30\servers\default\scb\WEB-INF\classes is supposed to be on your
classpath.  Is this the classpath in JRun (viewable from the JMC) or the
machine's system variable (if on NT) or environment variable on UNIX?

javax.servlet.ServletException when running struts-example on JRun 3.0 / NT 4.0 SP5

[Guillaume Lahitette]

Hi all,

I deployed the release v0.5 of struts-documentation, struts-test and
struts-example WAR files into my JRun 3.0 server.

struts-documentation and struts-test run perfectly fine but when I invoke
http://localhost:88/struts-example/, I'm faced with the exception below.

I've checked servlets are preloaded correctly, all TLD files are present
where expected, etc

I included an output of my CLASSPATH to help find out what ressource is
wrong/missing

Thanks for your help!!!

Cheers,

Guillaume.

Using the current builds, you would do something like this (taken from
the example application). 

Build a bean to hold the collection of radio button options. Store it
in the request context.

<%-- In real life, these would be loaded from a database --%>
<%
  java.util.ArrayList list = new java.util.ArrayList();
  list.add(new org.apache.struts.example.LabelValueBean("IMAP
Protocol", "imap"));
  list.add(new org.apache.struts.example.LabelValueBean("POP3
Protocol", "pop3"));
  pageContext.setAttribute("serverTypes", list);
%>


Reference the bean in the options tag.

  

  

In your case, I think it might be

RE: Please Help: Struts issues in Weblogic5.1.0 (sp5+)

[Anderson, Trey]

In reference to your question, it looks like WLS 6.0 has changed it's classloader 
hierarchy to be more J2EE compliant.
As a result the servlet's and the jsp's have the same classloader identified by 
object.class.getClassLoader().  With
respect to classloaders, all seems well with WLS 6.0.  However I just got it to work 
last night.

As for WLS 5.1 spX the only hope I've found is a hack provided by Erik Pearson at the 
following URL.  I have not
attempted his suggestion.

Subject:Ang: Please Help: Struts issues in Weblogic5.1.0 (sp5+)

I have encountered exactly the same problems and solved them the 
same way as described by Eric Pearson. This solution seems to work 
well as long as we run on WLS 5.1 sp6.

There is another issue though. In WLS 5.1 sp8 the load-on-startup 
tag in the deployment descriptor has been fixed and works as it should.
This sounds nice at first but the problem is that this causes the 
servlets to be loaded before the jsps and therefor loaded by the 
wrong classloader. In other words, Struts does not work with sp > 
6.

If anyone has a solution to this problem I would really appreciate 
to hear about it.

I would also like to hear about experience running Struts on WLS 
6.0. Has anyone had any problems?

Greetings Magnus Petersson

I am new to struts and find it a very exciting and powerful solution 
which I would like to implement into all our
solutions.

After implementing a small sample application, I have encountered 
the dreaded ClassCastException and am trying to
understand it's cause and appropriate solution.  After navigating 
through past postings I have found the following
website by Erik Pearson.

http://archive.covalent.net/jakarta/struts-user/2000/10/0009.xml
 

On this site he goes into an explanation of the cause and a description 
of what seems to be the only solution.

1)   Could someone please validate this solution?
2)   Is there an alternative solution for avoiding this classloader 
problem?
3)   I read that the root cause of this issue is the fact that Weblogic 
5.1.0 is not 100% J2EE compliant.  If this is
true would using Weblogic 6.0, which is J2EE compliant resolve this 
issue?
a.   What new issues could arise?  Solutions?

I would very much appreciate guidance in this matter,

Re: Ang: Please Help: Struts issues in Weblogic5.1.0 (sp5+)

[Wong Kok Wai]

I've having no major problem with WLS 5.1 sp8. I find
sp8 is rock solid for Struts and I don't need to apply
any of the workarounds (like adding a startup class).
The only exception I like to add is I'm deploying my
web application in an un-jarred fashion.

AW: Container doesn't seem to allow *.do

[Oliver . Lauer]

Hi, 

I work with Iplanet6.0 and the *.do-URL works fine using within any JSP-Page
as action-parameter in a form-tag and within requesting directly via URL,
but it doesn't work using a *.do-URL as a forward-tag like: . 

Here I have difficulties in calling:

 RequestDispatcher rd =
getServletContext().getRequestDispatcher(path);
rd.forward(request, response);

with the follwing IPLANET6.0-message:

'SERVLET-filetype_not_mapped: Mime mapping not found for file, while
displaying static content'

Does anybody if and how it works with IPLANET6.0 ?

Thanks
Oliver

I believe iWS 4.1 has the ability to map so maybe the same technique is 
possible in the app server - I have not done this myself, so it may be 
totally wrong, but check out the section, "Using Regular Expressions in 
rules.properties", Appendix C,  in the iWS Programmer's Guide to Servlets:

http://docs.iplanet.com/docs/manuals/enterprise/41/servlets/contents.htm
Obviously this is indirect help since you'll have to see if something 
similar exists for the App Server.

Re: Getting Struts to Work with Weblogic x.x SPx

[tm64]

Hi. 
So far, I use Struts privatly on TC3.2.
In order to use it at work (which would be just great!) it would need to function rock 
solid on Weblogic.
I did not try this myself yet, but I am reading the messages about problems. I 
understand that this is about servletengine specification vs. implementation. 
Can we - any soon - expect Weblogic (5.x) to be a stable basis for Struts or should TC 
be always seen as the better choice? Thanks.
