Re: Why I Hate Struts Modules

[Frank W. Zammetti]

Paul, you are aware that you can specify multiple configuration files, 
right?  There isn't even a need to use XML entities, which I suspect 
isn't as well-known as it probably should be, and another poster pointed 
out that it presents some troubleshooting (or was it validation?) 
problems.  I think multiple config files gives you what you want though.

Why I Hate Struts Modules

[Paul Benedict]

Great subject line, isn't it? :)

OK. I've been doing Struts for like 2-3 years now, and
Struts Modules I loved for awhile but now I absolutely
can't stand them

First off, my initial appeal to modules was to split
up the configuration files so different developers can
work on the project without people waiting for
check-outs. That sounds like a good deal, but Modules
are MORE than splitting up configuration files - they
are these Berlin Walls kind of construction where
forms and actions can't be shared across them 
unless you want to define them in multiple config
files.

See, after all these years, I really wanted was to
split files up. Modules don't gain me anything, do
they? I know (or I think) when Craig wrote Struts 0.x,
he had an action.xml which did something similar
Now I could create file of just actions and use XML
ENTITIES to include them, but I never see people doing
that solution. Is it not well-known or frown upon?

So I am kind of sick of Struts modules. More so, now
that I have to declare my Struts global exception
handler in every config file!! This gets ridiculous
after 5 modules... and forget about it if you have a
project with 50 modules.

Too much configuration duplication.

This change fixed it for me.  I am not sure why because I had already

Can you include your Tiles definition and your jsp using tiles so we can

Re: Is the best way to have multiplestruts-config.xmlandtiles-defs.xml files, modules?

[Kishore Senji]

TilesPlugin doesn't configure the TilesDefinitionsFactory once it is already
configured, so, if you use comma-separated xml files you would to declare
all your tiles-definitions in only one xml file. Similarly for Validator --
ValidatorPlugin overrides the resources from subsequent calls to its init
method, so you would have to declare all the validator resources in one xml
file.

Also it is always better to prefix action paths and tiles-defs based on the
xml file. That way it totally eliminates the possibility of silently
overriding action-mappings, tiles-defs of one xml file by another xml file.

You can have multiple Struts config files without using modules:

http://struts.apache.org/api/org/apache/struts/action/ActionServlet.html

findforward w/session objects

Hello
When I use the code below the Action "playThis" claims
the file attribute is null.  It is not unless I am
loosing the session on the findforward.  How can I
store a value in the session and forward to an Action?
 The first line of the "playThis action is String file
= (String) request.getAttribute("file"); so why is
attribute null?  Any enlightment welcomed.

System.out.println("file= "+temp);
session.setAttribute("file", temp);
return actionMapping.findForward("playThis");

You can have multiple Struts config files without using modules:

Just tried this. This works nice. Only downside is that then you don't

Re: Is the best way to have multiple struts-config.xml andtiles-defs.xml files, modules?

No, in our case it's mostly to make the code manageable. We're putting
code into separate packages and separate JSP directories, but it's all
going to be part of the same application in the end. And avoiding
modules wold be nice if possible.

If you are using myfaces runtime, you need to add a preprocess filter command.  
The usecase has an example 
(http://svn.apache.org/viewcvs.cgi/struts/shale/trunk/use-cases/src/web/WEB-INF/chain-config.xml?view=markup).
  This command captures the file suffix before myfaces changes the viewid 
suffix.  If you are using only Clay full html views in your project, you might 
try changing the default "javax.faces.DEFAULT_SUFFIX" to "*.html".  

Another thing you might try is turning on debug for a couple myfaces classes in 
the java logging.properties file.
org.apache.myfaces.application.NavigationHandlerImpl.level=ALL
org.apache.myfaces.application.ActionListenerImpl.level=ALL

My action handler is not being called so the navigation is not occuring

Re: Postback not occuring for Clay html full view

[Martin Gainty]

Ryan

the Clay dcumentation at
http://struts.apache.org/shale/features.html#view
For each JavaServer Faces view that you wish to associate with a 
ViewController backing bean, you must:


 a.. Implement the ViewController interface. The most convenient way to do 
this is likely to be extending the convenience base class 
(org.apache.shale.view.ViewController).
 b.. As required by the JavaBeans specification, provide a no-args public 
constructor.
 c.. Declare your backing bean as a managed bean. In nearly all 
circumstances, you will want the bean to be placed in request scope.
 d.. (Optional) Provide public JavaBean properties that may be set to 
customize the functionality provided by this bean. Typically, such 
properties will be configured based on the managed beans configuration 
defined in the JavaServer Faces configuration resources for your 
application.
 e.. Ensure that the functionality of your backing bean is not dependent 
upon the order in which property setters are called, since managed beans are 
configured via the "setter injection" pattern.
 f.. Create event handlers for the lifecycle events of interest, plus 
standard JavaServer Faces event handlers for things like actions and value 
changes.
 g.. (Optional but recommended) write a corresponding JUnit test case using 
the Shale Test Framework. Because nearly all of your property and event 
handling methods have no JavaServer Faces API dependencies for their 
parameter signatures, it is generally quite easy to write such tests.
whith regards to your missing boolean property 'postback' for your backing 
bean the doc states
Each backing bean that implements ViewController will support a boolean 
property postback, which will be set to
true if this view is the one that is processing a form submit previously 
rendered by the same page, or

false if this view was newly navigated to.

The property will be set before any of the lifecycle methods described below 
are called, so that application logic may perform conditional tasks based on 
this state.


Off the top I dont see your postback attribute

Hope this helps you out,

I am using shale/clay html full view.  I have an initial page, index.html,
which contains a commandLink to another page, page2.html.

My action handler is not being called so the navigation is not occuring

Any ideas?

Re: startup time validator validation?

So I would like to be able to enforce the validating of the

I solved a similar problem at build using two different methods on 
several projects:


1) Generated validation.xml, torque schema, chunks of 
DynaValidatorActionForm form-beans for struts-config.xml, parts of 
application resources, java classes for marshalling within Actions (I 
didn't always use this part, actually :/ and JSP chunks (form tiles) 
from an over-arching XML configuration file. This doesn't do what you're 
asking, but it does make sure that things are in sync, and was actually 
kinda nice.


2) Used XML parser to check names of fields in validation.xml against 
struts-config action "name" attributes linked against struts-config 
form-bean defs, sort of like a 'diff' for various chunks of XML. This 
also ran as an ant task, not on startup or anything, but I suppose it 
could be adapted to that.


To me, this seems like a problem better solved during the build process 
rather than deployment/startup.

DynaActionForm, Boolean checkboxes, and Initial

[katre]

Hello all.

In my app, I use the DynaActionForm, because it makes it much easier to
declare all the forms I need.  However, it is giving me a problem with
Boolean type variables used in checkboxes.

Specifically, I have the following form-bean:





In my JSP, I have:



This is properly checked by default.

The problem is that when a user unchecks the checkbox, this is not
noticed in the form, due to the infamous
HTTP-doesn't-send-empty-parameters problem.  The canonical advice I have
seen is 'set the property to false in the form's reset() method'.

This has two problems:
a) DynaActionForm's reset does nothing by default.  Is there really no
support for this common thing in DynaActionForm?
b) I created a subclass on DynaActionForm, which had a reset() method
that only sets that property to false.  However, the ActionForm.reset()
method is apparently called via the  tag, (the doStartTag()
method calls initFormBean(), which calls the form bean's reset()
method).  This means that the checkbox is initially unchecked, and seems
to be a problem regardless of using DynaActionForm or not.

So, my question is: how can I have a Boolean checkbox that defaults to
true, and yet can tell when it is unchecked, and still use
DynaActionForm?

Thanks,
katre

Re: Submit buttons getting their value

[Richard Yee]

D.J.,
Perhaps you should try it yourself. It works for me.
If the html:submit tag is used, and the property
attribute is specified, then that property is
available in the action class as
request.getParameter("the_submit_button_property_name");

I don't see any code that wraps HttpServletRequest.

There is no such attribute on the  or 
components, because in HTML that is not what determines where the submit
goes -- it's the "action" attribute of the parent form component that
determines that. The only way to do what you're describing is to have some
client side Javascript that goes and messes with the action attribute before
calling document.submit().

Of course, doing this means you're throwing away the current component tree,
so it kind of defeats the purpose of using JSF in the first place. If you
want alternative processing of the same input data based some environmental
conditions, that's whay DI frameworks like Spring or Hivemind let you build
up on the server side -- just use them in the action method that handles the
submit to do what you need, without trying to mess around at the HTML level.

OutputLink does not seem to submit a

Nope ... that's why  exists, to provide you something that
looks like a hyperlink but actually does submit the form.

Accessing Struts portal via Netscreen

[Radhika Sarang]

We've installed a Struts based portal on our test system(Solaris box).
When we test inside the network everything works fine.  But if we log in
from outside the network via Netscreen(there is an IP address
translation that happens), the first login page takes over 5 minutes to
appear. But once the login process is complete, all clicks from there on
works just fine.  Another portal(that doesn't use Struts) has no such
problems.  
 
Here's some details:
 
Servlet Engine: Tomcat (from within JBOSS)
Web Server (installed on an external web server) :  Apache
 
The mod_jk.conf file on the external web server:

 
JkWorkersFile /opt/tomcat/conf/workers.properties
JkLogFile  logs/jk.log
JkLogLevel warn
JkMount /*.jsp ajp13
JkMount /servlet/* ajp13
JkMount /adminportal/* ajp13
 

 
 
The URL : http://  /adminportal/Welcome.do
 
 
Appreciate any help we can get on this problem.

in the finally clause, check if the connection was opened, if it was, close
it. IMHO, it might be better to open and close your connection in the method
that make the call to the DB which would be synchronized for security sake.

not sure what you mean by leakage but I use Hibernate so I'm not concerned

Re: html tags not parsed by taglibs

no, it's not the taglib that isn't parsed but the html tags in the
property's string to be written by the taglib.

When you say "bean:write is not parsed", you mean that in the html source
that's generated you see "bean:write" in it? If so, you might have just
forgot the bean taglib reference (<%@ taglib ...%>)

I guess this makes me the whipping boy for a while.

Re: how to sustain the sanity of the connection pool

[Ronald Holshausen]

Another solution is to use a proxing framework (like spring), that
opens and closes the connections for you. This way you know that the
connection will always be closed after the method call, regardless if
there was an error or not.

You can also create a base class for all your actions that has a try
{} finally{ connection.close(); } statement so that your connections
are always closed. But I think the DAO pattern is probably the best if
you want to keep your actions and data access code seperate.

Also look at the commons-dbutil library, as it has a nice closeQuitly
method so you can close a connection without catch for the
IOException.

Re: how to sustain the sanity of the connection pool

[Murray Collingwood]

A pertinent question, had the same problem myself this afternoon.

I use Tomcat DBCP and found that each connection really does need to be closed. 
 If 
you don't your pool of connections is quickly depleted.

>From the many code samples I have looked at (not that many really) I find many 
>people 
extend the MVC concept to MVCD where D is the "DAO" or Data Access Object.  In 
my 
recent app I have declared a Dao class that provides by abstract database class 
and 
then defined all my databases to use this Dao super class.  I then have 
standard 
functions in the Dao class for managing my connections.  The connections 
themselves 
all come from a function in my persistence class (like a Manager.class with a 
getInstance() function).

Finally I can put println() calls in my persistence class to count the usage.  
This is of 
course very manual, maybe somebody has a better method.  What would be nice is 
if 
Tomcat had some monitor for the connection pool that we could watchprobably 
need 
to direct that question to the Tomcat list.

Visually my stuff looks like the following:

public class Manager {
private static Manager manager = new Manager();

public Manager getInstance() {
return manager;
}

public Connection getConnection() {
return dataSource.getConnection();
}

...a few other methods to support the above...
}

public class Dao {
/** Creates a new instance of Dao */
public Dao() {
try {
Manager.getInstance().connections += 1;
System.err.println("");
System.err.println("* Open connection=" + 
Manager.getInstance().connections);
connection = Manager.getInstance().getConnection(); 
if (connection == null)
System.err.println("ERROR: Dao: Failed to establish connection 
== null");
} catch (Exception e) {
System.err.println("ERROR: Dao: " + e.getMessage());
}
}

public void close() {
try {
if (rs != null) rs.close();
if (statement != null) statement.close();
if (connection != null) connection.close();
} catch (Exception e) {
System.err.println("ERROR: Dao: " + e.getMessage());
}
System.err.println("* Close connection=" + 
Manager.getInstance().connections);
System.err.println("");
Manager.getInstance().connections -= 1;
}

   ...lots of other methods to do stuff to the database...
}

As you can see in the above two methods I have implemented a counter, this 
serves to 
write to the log the number of connections in use at any one time.  The count 
of course 
goes up and down as I move from page to page, but at the end of any page being 
posted it should continually return to zero.

As in this output:

* Open connection=1

* Open connection=2

* Open connection=3

* Open connection=4

* Open connection=5

* Open connection=6

* Open connection=7
SQL:  SELECT itid, icid, stocode, sloname, stoname, scontent, iduckrank, irank, 
iduration, simagename, ddateStart, ddateStop FROM Tour WHERE itid = '3' LIMIT 
0, 
50
* Close connection=7

* Close connection=6

* Close connection=5

* Close connection=4

* Close connection=3

* Close connection=2

* Close connection=1


Good luck

how to sustain the sanity of the connection pool

[emre akbas]

Hi,
I have some general questions about connection pooling and exception
handling.
Struts suggests that developers use declarative exception handling. In
declarative exception handling, there are almost no "try { } catch() {}"
blocks in the Action classes. Exception occuring in Action classes are
handled by exception handlers outside the Action classes. Everything seems
OK so far.
It is very usual that we open a connection to the database at the beginning
of the Action class and then close it at the end. When an exception occurs,
an exception-handler outside of our Action class (in which the exception is
thrown) handles the exception. Then, what happens to the connection? We
weren't able to close it, so does it continue to allocate a connection from
the pool?
My other question is about the connection pooling itself. Are there any
tools or ideas to monitor the sanity of the connection pool? Are we somehow
able to find the classes where leakage occur?
Thanks in advance.

Re: html tags not parsed by taglibs

When you say "bean:write is not parsed", you mean that in the html source
that's generated you see "bean:write" in it? If so, you might have just
forgot the bean taglib reference (<%@ taglib ...%>)

Hi,

When I hardcode something like hello between

and  in my jsp page, it works.

if I put the same string in a property and use it in a bean:write, it's
not
parsed, the page shows the whole string which is not what I need.

Is there a way to make the bean:write parse the string in the jsp? And can
someone explain to me why bean:write acts like that?

Thanks

Directory acces depending on user connected...

[Gaet]

Hi,

I have an application where I store PDF of each of my client...
I would like to know how to restrict the view of PDF to the client that PDF 
belongs to

Actually to view PDF I have a link like this :

www.mywebsite.com/mystrutslink.do?pdf=/pdf/clientId/test.pdf

As you may notice, the problem is that the link is displayed and if the client 
change the id by the one of another client he will see his PDF...

Thanks for your advices on this problem
