Re: [Newbie] html:link

[tyler]

Hi Silmane,

you may have already received a reply regarding this but none the less
this is how I've been doing it.

If you place a java.util.Map into the request the html:link tag will
then build
the parameter list for you where the keys are the parameter names and
their
values the parameter values (of course).

In your case your iterating over a Collection of beans and from that
collection
you would/could provide a method to return the Map.

In my example I have a Vector of 'foo.Bar' objects where Bar objects
have a getter
method for the map property.  My Vector of foo.Bar objects is an
attribute of the 
request stored under the key 'things'.



linkname 


The documentation for the link tag is of course located at:
http://jakarta.apache.org/struts/struts-html.html#link
There are a couple of restrictions I didn't mention documented there.

Someone just helped me out with this a few days ago so to whomever it
was thanks.

RE: CachedRowSet for html:options

[Sunder R Somasundaram]

Thanks for your reply; it is a select box with single or multiple
options. Do I have to put in both the values and the labels even if both
are the same?

Subject: Re: CachedRowSet for html:options

You mean you're displaying a list in a table or you are displaying a
select drop-down box?

The html:options tag works great with forms, it'll initialize the select
box to what's in the form object, and it'll display appropriate labels
and set up the appropriate values on each option.

You can quite easily use the CachedRowSet.toCollection(column) to return
any column of the rowset as a collection. Instead of putting the whole
rowset in the session, you'll have to put a collection for the values
and a collection for the labels. A few more lines of code, yes, but not
exactly difficult.

If your lists are just lists and not select boxes (it's not clear from
your message), use a logic:iterate tag.

I do my own "custom" thing on top of Struts (and I think a few non-ejb 
people advocated custom solutions).
I will be posting a "solution" on source forge as a Struts sample, I 
think this week.

For presistance I use CachedRowSet. Since they are SQL commands, they 
are very scalable.
For autorization I use container JAAS (table based)
For most others, Struts would do.

I also plan to expose my data/model layer as a Soap service for non -

Re: What's the rigth way to do it ?

[Bin Zhou]

Slimane

Neither way will work for you as the session object will be for a single 
user only. Putting things in the URL query string has the same effect. What 
you should be looking for may be Appliation scope object or some other ways 
like persist the data to the database or server file etc.

Hope this helps.

I still think that this is a classpath / classloader problem.

I managed to duplicate your error message by putting a reference to the
servlet.jar file in Project Properties | Web Server | Tomcat 4.0 | Required
libraries tab - I hate the way JB hides all these settings - far too
complex!

Building Struts From Source

[Suneet Shah]

I am trying to build struts from the source in an attempt to resolve a parsing problem 
I am experiencing.  The documentation on the site mentions that the commons-* jars are 
prerequisites for this. However, in reviewing the build.xml file, I don't see any 
reference to this. Also, the docs mention the need for a commons-digester.jar.  There 
is already a disgester.java in struts itself. Which disgester should be used?  The 
problem I am experiencing is in the digester which is the reason for my question.

Any help would be greatly appreciated.

Best Regards

What's the rigth way to do it ?

[Slimane]

Hi,

I have a set of Objects (mainly Strings) that I would like to share inside 
my web application for each user. So I was thinking about setting all these 
objects using the HttpSession object. (using the methods getAttribute() and 
setAttribute()).

But in a second thought, as there are only a few String that I need to 
share. I could easily pass them as parameters to my Action classes.

So, I was wondering what's the right way ? If there's only a few Strings, 
isn't it easier to pass them as parameters instead of using the session 
object ?

Thanx in advance for your replys.

Friendly Regards,
Slimane

EBJ Alternatives?

[Gabriel Sidler]

A couple weeks ago there has been an intense discussion on
this list about the use of EJB. Many people were quite
critical or at least cautious about EJB. I'd appreciate if
some of you could share what alternative component
architectures/frameworks you are using.

I'm now starting on a new web project where distribution and
transactions, two of EJB's main feature, are no requirements.
The application is a web-based collaborative system with a
rather complex application logic but little database involvement.
There will be clients using HTML/HTTP and other using a SOAP-
like protocol. I am planning on using Struts for the Web-tier
and am looking for a component framework to implement the business
logic/data tier. If feel that EJBs wouldn't be the right technology
for this but am wondering what alternatives are. The things I
would like to see in such a component framework are:
- component life cycle support
- support for component relationships
- component naming and lookup
- authorization mechanism
- web request dispatching
- subscription/notification service
- logging
- configuration
- persistence
- some modularization concept
- some error handling concept

How are you implementing this? Any framework you can recommend?
Thanks for sharing!

Gabe

Here's some usefull sites:
1) http://www.husted.com/struts -- Ted Husted's site, lots of stuff
there
2) http://stealthis.athensgroup.com/presentations/ -- a white paper
on Struts, assembled by Larry Maturo
3) The book, "Professional JSP : 2nd Edition" (Wrox Press, ISBN
1861004958), has an excellent chapter devoted entirely on Struts

Hope this helps.

Re: CachedRowSet for html:options

[Adam Hardy]

You mean you're displaying a list in a table or you are displaying a select drop-down 
box?

The html:options tag works great with forms, it'll initialize the select box to what's 
in the form object, and it'll display appropriate labels and set up the appropriate 
values on each option.

You can quite easily use the CachedRowSet.toCollection(column) to return any column of 
the rowset as a collection. Instead of putting the whole rowset in the session, you'll 
have to put a collection for the values and a collection for the labels. A few more 
lines of code, yes, but not exactly difficult.

If your lists are just lists and not select boxes (it's not clear from your message), 
use a logic:iterate tag.

Does anyone know of a way to reproduce the refresh functionality in a link
using the struts taglibs and no scriptlets? E.g. something like:

Refresh this page

I'm not sure how to derive the  without using scriptlets.

Thanks,

Re: [Off-Topic ?] Problem with Struts/Tomcat/Jbuilder/ ?

[Slimane]

hello David

thanx for your help :) But it still doesn't work :(

In the properties of my webapp, the servlet library of Tomcat was indeed 
excluded, so that isn't the problem.

The weirdiest thing, I think, is the fact that this happens only the second 
time I run my webapp. And it doesn't happen occasionnaly but every second 
time !
Could it be related to a session bean which isn't successfully removed ? 
Because I don't see what else could generate that exception.
(javax.servlet.ServletException: duplicate class definition: 
org/apache/jasper/runtime/HttpJspBase)


Friendly regards,
Slimane

Sorry - quite correct - there should be reference to the servlet lib in the
project properties - however, in the webapp properties (right click hand
holding globe) you should make sure the the Tomcat 4.0 Servlet lib is
Excluded from the webapp.  Otherwise, JBuilder will put a duplicate copy of
servlet.jar into the WEB-INF/lib directory and into your .war file - could
this be the problem?

I'm convinced that this must be a classpath/classloader related problem and
not that TC or Struts (or JB for that matter) are fundamentallty flawed.

I occasionally see this in the JB browser:
javax.servlet.ServletException: duplicate class definition:
javax/servlet/jsp/JspTagException
But NEVER when the app is deployed!!

iPlanet-struts

[yogesh b]

I have been trying to migrate a struts web app from Tomcat 3.2 to iPlanet WS 6.0. I am 
new to iPlanet. The deployment looks to be smooth but I get an error while loading the 
application which says that "Cannot resolve external entity" for the struts DTD, while 
initializing ActionServlet.

Please help.

Re: Dynamic Chinese (Big5 and GB) front-end input

Subject: Re: Dynamic Chinese (Big5 and GB) front-end input
From: "Tea Yu" <[EMAIL PROTECTED]>
 ===
I can't wait for a fix on integrating a characterEncoding filter to struts
but hardcoding it in ActionServlet.  Anyway, for those who work on
language specific (esp. Chinese) projects please feel free to commend my
idea..

I'm using Postgresql which supports different Frontend/Backend encoding
scheme.  For example, I can insert into a backend "euc_tw" (Chinese)
encoding database either Big5 Chinese or GB2312 Chinese records.  Later on
any record can be retrieved either in Big5 or GB or something.

In the real world I'm not sure when Big5 users or GB users will submit
form data in Big5/GB..  so I utilize ServletRequest.setCharacterEncoding()
in servlet 2.3 before populating formBeans in the below priorities (from
the highest)

clues from browser//not likely
defined in session attribute//idea from Tomcat 3.3
default servlet config

I'd also like to hear from anyone who did something similar before.
Thanks!
