Switch Action

[Sahil Gupta]

Hi, 
 
Can anyone tell me how to use Switch Action in my project. My project
consists of more than one module and I need to forward from one to
another file in different modules. 
 
Are there any good links available to get more information about it.
 

Regards,

Sahil Gupta

This error implies there is something wrong with your configuration, and
that the registration of the resource did not get completed successfully.
In my experience, there's usually a stack trace in the Tomcat logs that says
why it didn't get processed.   You might also want to add a call to:

e.printStackTrace();

inside your exception handler to see where the error is actually coming
from.

I don't use Tomcat 5.5 much myself (primarily 5.0) so I can't help you much
more than that ... best bet would be to ask questions on the Tomcat user
mailing list.

when I click this submit button,it should submit to B.do and show some
information on screen,but in fact it doesn't work,when I use

A.jsp to B.do?
My code is follows:

Re: Some questions

[Comain Chen]

I have used Eclipse+Myeclipse to develop, and it is quite convinient, At
least the build and deploy process can be done in a single step with
myeclipse.  Somes your change in your code does not affect dramaticly,
tomcat with hot deploying will handle it withour restarting, but the
othertimes you do have to rebuild the project and restart the server.

Some questions

[Mário Lopes]

Hi.

First off, a little bit of my background. I've been developing with
Java for a long time now. None of it was web based development. On
this field, I've programmed with PHP, .NET, Ruby on Rails, Python,
etc..

Now that I'm encharged of developing a Java/JSP/Servlets application I
had to decide about a framework to ease my life. It had to have a
strong MVC pattern to enforce organization. So I picked Struts :-)

Now that I've given it a test drive, some questions arose:

1) I tried using Eclipse, as I've always did, for developing. What IDE
do you suggest?
2) I noticed that each time I did a simple change I had to build with
ant to package a .war and then restart Tomcat to recognize it. Tomcat
takes 20 secs to load which is absolutely unbearable. Is there a more
agile way of doing things?
3) Is MyEclipse worth it?

I think this is it.. for now :-) I'll be forever in debt for your kind replies.

Mário Lopes

Description: S/MIME Cryptographic Signature

[using class.forname()]

[temp temp]

I am using class.forname() in several classes  to load other   classes  so that 
 my application can be configured without  changing the exsisting code .
  I am not very clear about the issues which can come across using  class 
loaders .
  I tested in my localhost where all classes reside in one  container, it works 
.
  But in  production and tdl ,the  environment is  clustered   and app tier and 
web tier are seperated  so  could there be issues with class.forname() or  
dynamically  loading  classes which I donot see in my development  environment  
but can arise in production  because of  clustering or seperation of web tier 
and app tier.
  Thanks & Regards

RE: Issue while migrating from 1.0 to 1.1

[Olivier Citeau]

Hi Tim,
  Thank you for your answer.
  Now I see that I was not clear and I apologize for that.
   
  We migrated a project from :
  WSAD 5.0 / J2EE 1.2/ JDK1.3 (Websphere 5)
  to 
  RSA / J2EE 1.4 / JDK 1.4 (Websphere 6)
   
  We discovered the hard way that RSA's migration assistant suck.
  Our ".ear" was both j2ee1.2 and j2ee1.4
   
  So in order to get a j2ee1.4 ear I started a new blank project from RSA. RSA 
has Struts support, and I guess that it is 1.1.
   
  Tim, I solved my first issue before posting (Error 500...).
  It appears that if you do not specify anything about ressource bundle 
(neither in web.xml nor in struts-config.xml) Struts 1.0 is looking for 
"struts.properties" whereas Struts 1.1 is looking for 
ApplicationRessources.properties.
   
  So, yes I have this file "struts.properties" and my error template are 
defined there.
   
  Now here is my issue.
  In the form, if the user forgets a mandatory field, I do something like :
errors.add (...
...
return errors
  I do not use saveErrors(), because I use it only in the action.
   
  With WSAD/ Struts 1.0 it works fine : stay on same page and display errors.
  With RSA/Struts 1.1 it stay on same page and display nothing.
   
  And it is the same code !
  Same jsp, same form.
  As if the  tag stopped working.
   
  I try debugging, using request.getAttributeNames() from the jsp, but I found 
nothing even on Struts 1.0 where everything works fine. Thus my question of 
where Errors object are stored.

This language is telling Struts that there's a file named
"struts.properties" in your /WEB-INF/classes directory that has the
definitions of the strings referenced in your ActionError classes.

Does "struts.properties" exist? Have you defined your error template
strings there?

I'm not sure what you mean. What errors? In Struts 1.1.x, when you call
saveErrors(...) in your Action.perform function, the ActiveErrors object
is stored in the HttpRequest object.

Struts Forward and URL prefix problem

[Jeff Thorne]

I am trying out struts action mappings and wildcards so that I can provide
my dynamic content static URLs that are

not based on query strings.

 

When my action class forwards to success or failure all the URLs in the
receiving .jsp page are prefix with the initial URL.

 

For example if I submit the following URL to my action class

 

http://www.example.com/getCompanyDetails/companyName/postalCode/CEO all the
urls in the receiving .jsp file look like

 

/getCompanyDetails/companyName/postalCode/CEO/contactUs.jsp - a contact us
link in my footer 

 

Here is my action definition:

 



  

  



 

Any advice you have on how to solve this would be appreciated.

 

Thanks again.

 

Cheers,

Jeff

That's correct.  The data is stored in a map in session scope.  This is an 
attempt to cheat the complexity of the UIData component.  What the clayForEach 
component does is creates a naming container for each iteration.  It actually 
creates a grid of components versus the fly weight pattern that the UIData 
uses.  The data from the "var" attribute is organized in a map in session scope 
and the managed-bean-name symbol injects the prefix binding to the map 
therefore the complex decode in the UIData is not required.  The clayForEach is 
not a decendent of UIData.  It's just a dynamic way to create a grid of JSF 
components that have a strategy for binding.

The clayForEach is a "RUNTIME" uses of the clay component so this setup only 
happens when the view is created.  I think that is what is causing your 
problem.  You need the view to be recreated each time you select a race.  I 
would try adding a navigation rule back to the same page from the command that 
is associated with selecting a race.

If that doesn't work, I would suggest using the tomahawk dataList component.  
The clayForEach is a kluge in comparison.  

Example of the dataList:

JSP already works with Java objects. I guess what you meant is "to
pass java object to client-side HTML/DOM". You cannot send Java to
HTML page, but you can send Javascript object, search for "JSON". You
can also sent XML structure and parse it on the client.

Search for: "partial submit", "Google suggests", "in place update", "AHAH".

Plugging my product in: JSP Controls Tag Library provides in-place
update and Struts integration. Th partial submit feature is exected in
the next version, which should be released in about a week. But if you
are looking for something to use right now, google the keywords I
listed above.

It does not, I tried it ;-)

On the other hand, there is no sense in using XHR to initiate full page reload.

Re: using AJAX and Struts Action class how to refresh data on jsp page

I dont want to update all the jsp page, only the last
name text field,
I am able to do so if i do 
PrintWriter out = response.getWriter();
out.println(last);
return null;

but suppose, i have 10-15 fields that need to be
updated, how will i pass data ack to jsp
Is there a way to pass java object to jsp, and then
some how refresh these 10-15 fields.
I dont want to write html generating code in
ActionClass, but just send data and jsp handle it. and
refresh those 10-15 fields

I have looked at DWR also, but it only handles Java
Beans, how do i make it call ActionClass, i need this
because i have to get information about session,
request, servlet context and then process data.
Is it possible to do get all this information using
DWR and also about security, i have ServletFilter in
place which checks few things for security, how will
it be affected uwing DWR

[Shale] CLayForEach and var attribute

[Hermod Opstvedt]

Hi

I have a situation that I am struggling a bit with. On a page that I have, I
have a page that displays different races and has a clayForEach tag that is
supposed render a jsfid that displays information about a classes in a race,
and a dataTable on that jsfid that displays the results for each class. What
happens is that when I first hit that page, the method that backs the
clayForEach is called, but when I change to a different race, the method is
never called again, but it displays the classes w/results from the initial
load of that page. I seem to remember something about the clayForEach tag
and the var being session scoped? Should I explicitly do a
getExternalContext().getSessionMap().remove("myvar") in my backing beans
init method?

Re: using AJAX and Struts Action class how to refresh data on jsp page

[Frank W. Zammetti]

That's true Brian, but if he doesn't have appropriate code on the
client-side to handle the response, it won't do much good in this
particular case.  Remember he's getting the response via XMLHttpRequest.

Then again, if you were to return a redirecting forward, that might do the
trick.  I'm actually not sure how XMLHttpRequest reacts to a redirect...
that's an interesting question :)

Re: using AJAX and Struts Action class how to refresh data on jsp page

[Brian Long]

Ashish,

There's a built-in method you can use to return to the calling jsp.

Try return (mapping.getInputForward());

from your Action class.

hope that helps,
-Brian

This is pretty much the exact opposite of what AJAX is for :)  Refreshing
the whole page is what your actually tring to avoid with AJAX.

You can populate the form fields yourself in a Javascript callback
function, or I suppose you could fire off a refresh of the page from a
callback if you really wanted to do that.

Have a look here:

http://www.omnytex.com/articles

This has an article about doing AJAX with Struts, and shows some examples
of updating form fields.

You may also want to see this Wiki page:

http://wiki.apache.org/struts/AjaxStruts

And, if you don't feel like writing the client-side code yourself, have a
look at this library:

http://javawebparts.sourceforge.net

Specifically, click the Javadocs link, and then navigate to the AjaxTags
package.  This is a taglib for implementing AJAX in an application, Struts
or otherwise, in a completely declarative fashion, without having to write
a lot (or any!) Javascript yourself.

Alternatively, I'm a big fan of DWR:

http://getahead.ltd.uk/dwr

Although AjaxTags will save you from writing a lot of script yourself, DWR
is a more RPC-like mechanism, and handles transmutation of Java objects to
Javascript objects, and really works very well.

action tag vanishing?

[Brian Long]

Greetings All.

I'm migrating an existing webapp to Struts.  An Action tag in my menu is
getting blown away.  The application is in the middle of migration, so
there are some struts-enabled jsps and some vanilla jsps.

On first navigation to the menu, the code works fine.  After navigating
to a non-struts page, then back to the menu, the url is corrupted - as
if the /viewGroupQuery link were redefined to "".

The Action is defined at session scope.  The corruption of the Action
remains across multiple sessions.

I'm using Struts 1.2.9 w/ Tiles.

Has anyone seen this behavior?

Thanks in advance,
-Brian

--- code snippets ---



 







  <% if (activeItem.equalsIgnoreCase("group.query")) { %>

  
  Query a Group

  <% } else { %>

  
  Query a Group

  <% } // END GROUP QUERY ACTIVE ITEM CHECK %>

using AJAX and Struts Action class how to refresh data on jsp page

[Ashish Kulkarni]

hi
I am trying to learn AJAX and struts together (will
use some standard solution later)
This is what i am doing, 
In my jsp i have 2 text fields FirstName and LastName
when the user enters FirstName and hits enter i call a
javascript which creates XMLHttpRequest objects, and
calls a Action class using GET , it send parameter as
name  some thing like this
GetNameAction.do?first=name

this Action class then populates last name, 
In servlet i would just do 
PrintWriter out = response.getWriter();
out.println(last); and works fine, but i dont want to
do it that way,
In Struts, i want to populate ActionForm, and then
refresh jsp page

How do i do it

This language is telling Struts that there's a file named
"struts.properties" in your /WEB-INF/classes directory that has the
definitions of the strings referenced in your ActionError classes.

Does "struts.properties" exist? Have you defined your error template
strings there?

>   By the way, where are errors message stored ? I found 
> nothing neither in the request nor in the session.

I'm not sure what you mean. What errors? In Struts 1.1.x, when you call
saveErrors(...) in your Action.perform function, the ActiveErrors object
is stored in the HttpRequest object.

"Servlet action is not available" almost always means that some exception
was thrown as the Struts action servlet was first initialized.  The
exception will be logged in one of the Tomcat log files
($CATALINA_HOME/logs/*).

In your particular case, the most likely problem is trying to use the Struts
data source.  This functionality was deprecated in Struts 1.1, and was
removed in Struts 1.2.  You should use the JNDI data sources provided by
your container (Tomcat) instead.  There is pretty reasonable documentation
on the Tomcat web site for how to set this stuff up, which applies to all
webapps, not just Struts based ones.


http://tomcat.apache.org/tomcat-5.5-doc/jndi-datasource-examples-howto.html

Historical note -- the only reason Struts 1.0 supplied a data source
implementation in the first place was that, six years ago, most servlet
containers did not support JNDI based resource access.  Now that they
(essentially) all do support JNDI, that is the recommended mechanism for
managing data sources.

Hi David,
Thanks for the reply.

Yes this portion of HTML code is in side Table definition.


The VO I am trying to access the properties in the tags is as follows:

public class TopupMethodVO implements Serializable{
  
private String topumMethod=null;
private ArrayList bundles=null;
private ArrayList selBundles=null;
 
public TopupMethodVO() {

}
// getter/ setter methods
 }

When I run http://localhost:8080/Test.do,it raise following error:
type Status report
message Servlet action is not available
description The requested resource (Servlet action is not available) is not
available.

When I removes data-source from Struts-config.xml,it can run well.But when I
add data-source into Struts-config.xml,it raise above erorr. I am puzzled
with it very much! Anybody can tell me the reason and how to correct it?

Thanks in advance!

Tomcat not starting

[Klaus Rohwer]

Hello together,

I have a problem with Tomcat not starting which seems related to using
Struts.

During startup Tomcat suddenly doesn't continue after having given out the
following lines:


03.04.2006 10:46:26 org.apache.struts.util.PropertyMessageResources 
INFO: Initializing, config='org.apache.struts.util.LocalStrings',
returnNull=true
03.04.2006 10:46:26 org.apache.struts.util.PropertyMessageResources 
INFO: Initializing, config='org.apache.struts.action.ActionResources',
returnNull=true
03.04.2006 10:46:27 org.apache.struts.util.PropertyMessageResources 
INFO: Initializing, config='myStruts.ApplicationResources', returnNull=true


I will give you excerpts of my web.xml file, of my struts-config-file and a
list of the jars I am using (cause it seemed to me that some JARS seemed to
cause trouble!)

1) web.xml


http://java.sun.com/dtd/web-app_2_3.dtd";>

  
action
org.apache.struts.action.ActionServlet

  config
  /WEB-INF/struts-config.xml


  debug
  2

2
  
  
action
*.do
  
  
login.jsp
  
  
... taglibs
  



2) struts-config.xml



http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd";>

  
... form-beans ...
  
  
... global-forwards ...
  
  
... action-mappings ...
  
  




3) JARs that I am using:

commons-beanutils.jar
commons-digester.jar
javax.servlet.jar
struts.jar
xmlParserAPIs.jar


Please tell me if you notice any mistakes!

Thanks a lot in advance and best regards,

Klaus

"Valid when"-Example

[Julian Tillmann]

Hi,

would someone be so kind to help me with the following problem:
 
A date field should only be validated 
if another checkbox isn't selected.
 
I'm not sure how to do it:
Do I have to use validwhen or reiqired-if??
I cannot find any good examples or references concerning my problem.

Here is my code snippet:





var
//-->this is the property that should decide if a check
is necessary or not (the bean-property of a html-checkbox)
(selectionForShift==false)



Help would be highly appreciated as this is really driving me crazy 

Thanks a lot
Julian
