Re: IoC Question with Alias
hi michael,
happened to me several times too :)
first you could try to define your services as proxy:
from:
binder.bind(HttpdRequestSecurityManager.class).withId("HttpdRequestSecurityManager");
to:
binder.bind(RequestSecurityManager.class,
HttpdRequestSecurityManager.class).withId("HttpdRequestSecurityManager");
if this is not enough try to break the dependency cycle by
injecting the ObjectLocator and creating the proxy manually
eg:
configuration.add( AliasContribution.create(
RequestSecurityManager.class,
locator.proxy(
RequestSecurityManager.class,
HttpdRequestSecurityManager.class)) );

IoC Question with Alias
Hi,
I have a problem with the contributions to the alias service. The
AppModule is ...
public static void bind( ServiceBinder binder ) {
binder.bind( SiteDispatcher.class ).withId( "SiteDispatcher" );
binder.bind( SiteServiceImpl.class ).withId( "SiteService" );
binder.bind( HttpdRequestSecurityManager.class ).withId(
"HttpdRequestSecurityManager" );
binder.bind( SiteBaseURLSource.class ).withId( "SiteBaseURLSource" );
}
@SuppressWarnings( "unchecked" )
public void contributeAlias(
Configuration configuration,
@InjectService( "HttpdRequestSecurityManager" )
RequestSecurityManager manager,
@InjectService( "SiteBaseURLSource" )
BaseURLSource baseUrlSource ) {
configuration.add( AliasContribution.create(
BaseURLSource.class,
baseUrlSource ) );
configuration.add( AliasContribution.create(
RequestSecurityManager.class,
manager ) );
}
The constructors of the services are ...
public SiteServiceImpl(
RequestGlobals globals,
ApplicationGlobals application,
Session session,
Logger logger,
Collection contributions,
SymbolSource symbols ) {
...
}
public HttpdRequestSecurityManager(
Request request,
Response response,
MetaDataLocator locator,
RequestPageCache requestPageCache,
@InjectService("SiteBaseURLSource")
BaseURLSource baseURLSource,
SiteService site ) {
...
}
public SiteBaseURLSource( SiteService site ) {
...
}
I get the [ERROR] Alias Construction of service Alias failed: Error
invoking service builder method
org.apache.tapestry5.services.TapestryModule.build(Logger, String,
AliasManager, Collection) (at TapestryModule.java:205) (for service

And I don't even have a clue where to look. I tried a lot of different
version with @Inject, with @InjectService("..") on the constructors the
contributeAlias(..) method. But none of them seems to work.
Any ideas?

Re: Page pool hard limit and page instance usage
Hi again,
I'm hitting my head to wall here with ServletContextSymbolProvider. It is
configured like this:
public static void
contributeSymbolSource(OrderedConfiguration configuration,
@InjectService("ServletContextSymbolProvider") SymbolProvider
servletContextSymbolProvider)
{
configuration.add("ServletContextSymbolProvider" ,
servletContextSymbolProvider, "after:SystemProperties",
"before:ApplicationDefaults");
}
public static ServletContextSymbolProvider
buildServletContextSymbolProvider(ApplicationGlobals globals){
return new
ServletContextSymbolProvider(globals.getServletContext());
}
And it always ends to this error:
java.lang.RuntimeException: Unable to instantiate class
org.apache.tapestry5.services.TapestryModule as a module builder: Exception

I can't determine where the recursion is. Is the ApplicationGlobals
initiating the construction of Alias service? If this is true then
ApplicationGlobsals cannot be used while I'm constructing my alias
overrides?
Is there anyone out there who has this working?

These parameters can be transferred to web.xml, so that recompile is
not
needed when changing these parameters:
public static void
contributeApplicationDefaults(MappedConfiguration>>> String> configuration, ApplicationGlobals globals) {
configuration.add("tapestry.page-pool.hard-limit",
globals.getServletContext().getInitParameter("page_hard_limit"));
}
and in web.xml
Some Tapestry 5 Application
tapestry.app-package
fi.hanken.resbuilder.tapestry5
page_hard_limit
60
This can be used through out every single service and page and
component.
To
access this in a page or component use:
@Property @Inject @Value("${page_hard_limit}")
private String pageHardLimit;
Injection can be used in service constructor also (I think) or by using
buildSomeService method instead of the usual binder.bind
Of course T5 makes it easy to read these from a file or database or
from
what not, but I have noticed that many admins accept editing web.xml
and
restarting the app ok.

Integration with GWT
Hi, I use T5 in my project as main web framework. The project itself is a sort of simple web GIS, based on Google Maps. There is great widget library for GWT to serve Google Maps with all their AJAX stuff, so I decided to use it also. Please, give me some information whether it's possible to integrate full lifecycle of GWT component with T5 as main framework? What I actually need is to be able to share some objects between Tapestry and GWT, but without page reload. So my GWT component should make its RPCs as usual, but these calls should be made after pressing button in Tapestry component and information should be got from that component too (@ApplicationState may be, but how to integrate it with GWT?)
