Re: Struts Tooling

Hi Robert -

A good example of tiles application is tiles-documentation.war
that comes with the Struts 1.1b3 distribution. The example
uses the ActionServlet (instead of ActionComponentServlet)
and it runs correctly (under WSAD 5.0 Test environment)
with a few modification.. as listed below.

You need to fix struts-doc-config.xml at:

RE: RE : Struts Tooling wsad 5

[Ying]

I am not sure if the build of WSAD matters... but who knows.
Unfortunately I don't have access to that particular version
of WSAD so I can't really say if this is the case..

But - taking a stab at your problem..
Looking at some struts code.. the message: 
"Can't get definitions factory from context" is thrown
as a FactoryNotFoundException by the method :
static public ComponentDefinition getDefinition(String definitionName, ServletRequest 
request, ServletContext servletContext) 
in TilsUtil class.

So - it looks more like a configuration problem. That is,
it can't find the definition files.  But - I am not sure why tiles-documentation.war 
did not work on your setup. 
Unfortunately I don't know where the documentation is
for using tiles for using ActionComponentServlet.
I would guess, that the reason ActionComponentServlet works 
is because your definition files are listed in your web.xml:

  definitions-config
/WEB-INF/tiles-defs.xml,/WEB-INF/tiles-tests-defs.xml,/WEB-INF/tiles-tutorial-defs.xml,
 /WEB-INF/tiles-examples-defs.xml


Maybe you've forgot to list them in your struts-config.xml
file?? as 
 


  


Just a thought.
Not a tiles expert here :)

Re: ValidatorActionForm example?

[Ying]

Hi Jeff..

This is what you need to do:
1. Define a form bean which extends ValidatorActionForm 
2. Define a action in which you use this form bean.  (suppose /myAction)

And in the validator.xml you need to do
   <--- the action that uses the formbean
   


Note that if you have another action defined using the same form bean..

   

A thing to remember if you are doing client side validation...

The formname needs to map exactly to the form name... (including the slash)
and because of the slash, the default generated name is invalid javascript.. so you 
need to use "method =" to specify the generated 
method.

Hope this helps.

Ying

RE: What is the best struts plugin for Eclipse?

[Ying]

IBM WebSphere Studio Application/Site Developer (not free)
has a struts plugin.  It has a editor (Web Diagram Editor)
that you can use for visualizing application flow,
in addition to alot of other stuff.

I can only find a tech preview blurb on it:
http://www7b.software.ibm.com/wsdd/downloads/struts_tools.html

It has been released (GA'ed) with WSSD.. as of last Nov.

See:
http://www-3.ibm.com/software/awdtools/studioappdev/
http://www-3.ibm.com/software/awdtools/studiositedev/

Trial version of WSAD is available (just search www.ibm.com)

and a white paper on how to write a simple struts app using it.

This is the scenario that I was trying to figure out.
Suppose in the struts config file I've defined a form bean name "logonForm"
and an action named "/logon" which uses "logonForm". And suppose that
in validate.xml I've defined 
  

   ... 


   ...

  

When the user clicks on a button that triggers a form submit 
via the logon action...  What validation takes place?

Maybe my question should be:  When does validation for form bean
gets triggered?  Is it any time that an action uses it or?

Does this apply to something like this as well?

   
 ...
   
   
 ...
   


Thanks!

The first form entry is possible because of the ValidatorActionForm class.
from:

http://jakarta.apache.org/struts/api/org/apache/struts/validator/ValidatorActionForm.html

"This class extends ValidatorForm and provides basic field validation based on an XML 
file. The key passed into the validator is the action element's 'path' attribute from 
the struts-config.xml which should match the form element's name attribute in the 
validation.xml."

So - I have an action name logon, and form bean logonForm which extends
ValidatorActionForm.  Action logon uses logonForm. I am guessing that -
when the path of action is executed, the "logon" validation entry gets
executed (and ignores the "logonForm" entry?)...

There is probably something missing from my question (due to probably still
lack of understanding of this). I'll have to just play with it :)
Thanks for having patience..

Problem using nested struts template tag

[Ying Gao]

I use nested template tag as the following:



  

  
 
 
 
 
  

  



template.jsp is a template that contains header, content and footer.
contentTemplate.jsp is a template that contains a title image and a detail
content jsp to which I pass myContent.jsp. It works fine except that the
browser (both IE and Netscape) keeps busy for a while after the page header,
content and footer are loaded. It seems that the browser tries to load
something else.
JavaScript won't work until the browser finish loading. I have no idea what
it is loading.
It only happens when I use template:put tag to pass a content
(myContent.jsp) to the nested
template (contentTemplate.jsp) without using 'direct="true"'. If I use
'direct="true"'
the browser returns immediately but that is not what I want. I want the
content to be
included instead of printed directly.
Does anyone know what the problem is? Is there any solution or workaround?
Thanks.

I'm starting to get burned by using  more than once in my

this...I have downloaded/installed the new nightly build for struts and

Is there a web-site/web-application that has an example of how to setup

The question is how to add or specify the datasource key value. I added the

The reason why the value is null is because that is the default when you
don't specify a "key" value for your datasource.  When that is the case you
will obtain your connection in the following manner:



   try {
  javax.sql.DataSource dataSource =
servlet.findDataSource(null);
  java.sql.Connection myConnection =
dataSource.getConnection();


  Once again, if you want to change the value from "null" to something
  else, just add " key=[something other than null] " to your datasource
  configuration.

  Hope that helps.

Yes, I did. I use my SQL and mine looks like this:



  

What else do I need to do to add this datasource to struts? Thanks.

Did you set up the data source configuration in your struts-config.xml
file?
I'm using oracle 8.1.6, my setup looks like this.

Hello All,

I am trying to connect to the database but when I do

DataSource dataSource =
(DataSource)servlet.getServletContext
().getAttribute(Action.DATA_SOURCE_KEY)
;

it gives me null as the dataSource value. Can anybody help me out here?
Thanks.

unload database

[Ying Teng]

How do I unload database to its persistent storage version? If we are
running directly out of a WAR file, saving cannot occur. How do we make the
save possible?

Thanks.

RE: database connection

[Ying Teng]

What you described is true. Now my question is how to get the datasource
without referencing the actionServlet. I wanted to intialize the database
hashtable of the databaseServlet class in the databaseServlet init function.
In order to do that, I need to get the datasource. But I can not reference
the actionServlet because the action is initialized after the database is
initialized (as in the log file). Hope someone can give me some hints.
Thanks.

You will add the key information to the datasource info in you
struts-config.xml file  it will look like this:


  

Then, after that's done, the easiest way to access it is to reference it by
the action servlet (servlet),  because using actionServlet you can just do
servlet.findDataSource("the name you called your datasource")  and voila,
you have your datasource object.  From that datasource object you can
create a connection.
If you cannot access the actionServlet, then it's a little more
difficult--and actually I wouldn't be able to help much there, but at least
your question would then be "how do I get the datasource without
referencing the actionServlet"

RE: database connection

[Ying Teng]

The ServletContext object of databaseServlet or the ActionServlet? Could you
be more specific? Thanks.

A reference to the DataSource is stored in the ServletContext object... You
can get it from that.

RE: database connection

[Ying Teng]

Yes, I can get the DataSource reference in the ServletContext object of the
ActionServlet class. But I want to get the reference to the dataSource in
the DatabaseServlet class. Can anyone tell me how to get the reference to
the dataSource from the databaseServlet class? Thanks.

update database.xml

[Ying Teng]

Hi all,

I have a question to ask. I want to update the database.xml file and the
database hashtable of the DatabaseServlet class every time the user
register. So when the user logs on next time (even after the tomcat is
restarted), he/she can still log on. Any idea?

Thanks.

Ying

P.S. I already successfully updated the database in the perform function of
the SaveRegistrationAction class.

destroy() of DatabaseServlet

[Ying Teng]

Hi All,

I noticed that when the tomcat shuts down, it does NOT call the destroy()
method of the DatabaseServlet class. How to let the destroy() method get
called when the server shuts down? Thanks.

Ying

RE: update database.xml

[Ying Teng]

This makes a lot of sense. Could you please describe the steps to deploy the
application with the deploy.tomcat Target of the Struts build.xml? Thanks.

Hi,

the problem is the logic of Tomcat. If you deploy the application as *.war
file
in the webapps directory of Tomcat, at start time a directory with the same
name as the *.war file will be created and the contents of the *.war file
unpacked into this directory. So far so good, all entries in database.xml as
in
in the *.war file are available.

During shutdown the database servlet overrides the database.xml file with
the
new User-list out of the hashtable, thats already fine. But after doing all
this work, Tomcat destroyes the subdirectory of your application!!!
Everything
gets lost.

If you deploy your application with the deploy.tomcat Target of the Struts
build.xml, no *.war file will generated. Instead the Applications
subdirectory
itself is created, so Tomcat leaves everything as it is. Now the Users are
written back to database.xml at shutdown and reread at startup of Tomcat.

Another possibility is to use an path to the database.xml file wich is
outside
of the webapps directory, but I don't know if there are limitations due to
security reasons.

Greetings
Uwe

setContentType() for xml output

[Wu, Ying (LNG-CIS)]

I need to send a string which represents a xml file to browser, I need to
call response.setContentType("text/xml").  But it is at ActionServlet level
and is default to "text/html".

1. Any idea?
2. I can do the output at MyAction.perform() level, but how to handle the
return type of this method?

Thanks.

Ying

Thanks John.

For now we simply stepped back to b1.
But maybe this indicates that your changes should be applied struts, so
