The annotation indicates which constructor you want injected (to the
framework as well as other programmers). What happens if you forget to
configure a PasswordHasher in Pico? No hashing? That's not very secure.
If you can't annotate a constructor (because you don't control the code),
you can use a custom provider. For example:
class HibernateUserManagerProvider implements ProviderHibernateUserManager
{
@Inject Session session;
@Inject PasswordHasher passwordHasher;
public HibernateUserManager get() {
return new HibernateUserManager(session, passwordHasher);
}

Re: Guice 1.0rc2
The architecture between webwork and struts2 has changed. Every other project that provides the same functionality, (e.g. Plexus, Spring, etc.) was written as a plugin in Struts2. Technically it is possible to use the object factories, interceptors, etc. without using the plugin architecture but it makes it much more difficult for end users. With a plugin, you can just drop it in, do some very minimal config and go.

Performance degradation for pages with long select
Hi.
I had Struts 2 performance problem for any page with very long select,
e.g., page with drop-down for all (2400) cities and all (2650) zips
for the state of California.
Such pages took 20-30 sec to be displayed.
Logs show that time was consumed somewhere after page generation.
Removing optional interceptors didn't help.
I replaced jsp with the page HTML source from IE ... the same
performance.
Extract from the page source is presented below.
It doesn't look right for the page having s:head theme=css_xhtml/
script language=JavaScript type=text/javascript
// Dojo configuration
djConfig = {
baseRelativePath: /custfind/struts/dojo,
isDebug: false,
bindEncoding: UTF-8,
debugAtAllCosts: true // not needed, but allows the Venkman
debugger to work with the includes
};
/script
script language=JavaScript type=text/javascript
src=/custfind/struts/dojo/dojo.js/script
script language=JavaScript type=text/javascript
src=/custfind/struts/simple/dojoRequire.js/script
Removing this AJAX related code has fixed the issue.
Questions:
1. Was AJAX template just forgotten in
struts2-core-2.0.6.jar\template\simple\head.ftl and can be safely
removed?
2. How (not existing in my application) /custfind/struts/dojo/dojo.js
managed to take so much time?
Thank you,
Nick

Extra parameter value for DispatchAction.
Hi,
Is there a way to pass a extra paramameter for DispatchAction apart from
parameter=method..
Onclick on a link(html:link action=/someform.do?method=getRecord) from
Search Results, I wanna to pass the primary key value. I can't use hidden
values as it is not a form.
I have one solution. But i don't know its proper approach. I tryig to set the
session in javascript and its not working.
onclick=javascript:clickRequestId(primaryKeyValue));
function clickRequestId(value) {
var primaryKey = value;
session.setAttribute(id,primaryKey);
}.
Any one has any idea please..

You can either build the URL via EL (by using the
html-el tags) or via the normal parameter map method
(see

I have one solution. But i don't know its proper

I'll admit I've never tried that approach... You may
have some very basic misconceptions about Javascript.

If you have one link per row then just add your PK to the link
directly. If you have one link per whole table then you will need to
modify the link dynamically with Javascript.
I have one solution. But i don't know its proper approach. I tryig to set the
session in javascript and its not working.
If it does not work then it's not a solution.
onclick=javascript:clickRequestId(primaryKeyValue));
function clickRequestId(value) {
var primaryKey = value;
session.setAttribute(id,primaryKey);
}.
Any one has any idea please..
You cannot access server-side session object from browser-contained
Javascript code. I mean, not in the fashion above. You need to read
sevlets/JSP book first to understand browser/server interaction.

Re: Performance degradation for pages with long select
Hi Nikolay,
Please try to ask questions like this on the user mailing list.
I'm going to take a stab at this, and say Dojo is your offender. There
is a setting in Dojo that will cause it to start parsing after the
page has been fully rendered (rather than during it), but I cannot
recall it right now. If you apply that setting, things should speed up
again. I remember a case where this was the problem, so it might be
the same problem you're hitting.
Kind regards,
Phil

Hi.
I had Struts 2 performance problem for any page with very long select,
e.g., page with drop-down for all (2400) cities and all (2650) zips
for the state of California.
Such pages took 20-30 sec to be displayed.
Logs show that time was consumed somewhere after page generation.
Removing optional interceptors didn't help.
I replaced jsp with the page HTML source from IE ... the same
performance.
Extract from the page source is presented below.
It doesn't look right for the page having s:head theme=css_xhtml/
script language=JavaScript type=text/javascript
// Dojo configuration
djConfig = {
baseRelativePath: /custfind/struts/dojo,
isDebug: false,
bindEncoding: UTF-8,
debugAtAllCosts: true // not needed, but allows the Venkman
debugger to work with the includes
};
/script
script language=JavaScript type=text/javascript
src=/custfind/struts/dojo/dojo.js/script
script language=JavaScript type=text/javascript
src=/custfind/struts/simple/dojoRequire.js/script
Removing this AJAX related code has fixed the issue.
Questions:
1. Was AJAX template just forgotten in
struts2-core-2.0.6.jar\template\simple\head.ftl and can be safely
removed?
2. How (not existing in my application) /custfind/struts/dojo/dojo.js
managed to take so much time?
Thank you,
Nick

Structly speaking using pico in a webapp requires no code at all (except of course container configuration in xml or whatever else) U, strictly speaking, that's still code. ;) Strictly speaking yes. But it is externalized and does not impose anything on used classes. What is with third party libraries, which do not know anything about guice? You can write a custom Provider as I illustrated above. Even more code which has to be repeated again and again . Or subproject proliferation... If I understood you correctly, in guice there will be need to write some adapter / factory. Who got more code? I'm pretty sure Pico is still more verbose. If you explain what your example is doing a little better, I'll be happy to illustrate. Well, it is just providing configured hibernate session and its lifecycle - basically open session in view So it registers configuration + session factory in application scope, and session lifecycle controller in request. What if I like to use another session impl in the same container? Use an annotation. And if I need to register the sme class more than once? Yet another annotation? And another one? You can override the scope in the configuration. You can also implement your own scopes and scope annotations. The users' guide explains this. And those scope annotations will leak into my original code. ( And I prefer my classes to be innocent, and not knowing that it is managed by Guice or pico or whatever else. Such dependency invalidates whole point of DI / IoC ) regards, [ Konstantin Pribluda http://www.pribluda.de ] Still using XDoclet 1.x?
