Hi all,
I wanted to share my strange use case and the errors I 'm facing in my way
to accomplish it, either way if none can help me this serves as a kind of
therapy don't you think?
The problem appears only after obfuscating the webapp do you think this can
araise problems with tapestry IoC? (I 'm just obfuscating my own
libraries... not third parties)
well, this is the case:
We 've already coded all the app when some guy says "it must not contain
the company's name in the whole deliverable" (he does some grep to control
this),
so we opted to obfuscate the code using Proguard, certainly we 're not
obfuscating all the code we 're just obfuscating to remove the trhee first
major packages (which contains the company name), methods and class names
and subpackages like pages & components are kept unchanged!
That done, we move on to test the web application after being obfuscated
and here I post the stactrace when I init the app in Tomcat 5.5.20 or Jetty
standalone 7.0.0:
It seems to be a problem while loading a Module named CustomSecurityModule
(we 're using tapestry spring security) and use this custom module to
contribute provider manager with an ldap provider.

the trace continues saying something like the last line.
When I run the same application *without* obfuscation on maven's jetty I
get everything working fine:

take a look, after adding module AppModule here it's adding also
CustomSecurityModule while when the error ocurrs..., this
CustomSecurityModule is not called.
sorry that I keep adding snippets but i 'd like to post the
CustomSecurityModule code:
package ar.com.company.cemiWebapp.services;
>
> import org.apache.tapestry5.ioc.OrderedConfiguration;
> import org.apache.tapestry5.ioc.annotations.Inject;
> import org.springframework.security.providers.AuthenticationProvider;

> contributeProviderManager(OrderedConfiguration<AuthenticationProvider>
> configuration,
> @Inject LdapCemiProvider ldapImecProvider ) {
> configuration.add("ldapCemiProvider", ldapCemiProvider);
> }

this is the AppModule code:

I 've tried this last class commenting out the contributeAlias method but,
everything kept the same way...
hope someone out there got some invoice for me :)
cheers and thanks in advance!
