Guys,
I removed the annotation to enable auto-wire with the following:
public abstract CryptoService getCryptoService();
I tried the following:
public IPage onFormSubmit(IRequestCycle cycle) {
try {
CookieSource cookieSrc = getCookieSource();
CryptoService cryptoService = getCryptoService();
Using the following hive-module.xml :
<service-point id="CryptoService" interface="common.crypto.ICrypto"/>
<implementation service-id="CryptoService">
<create-instance class="common.crypto.CryptoService "/>
</implementation>
RESULT...
getCryptoService() returns null
I even changed the service-id and id of service-point to have lower case
"cryptoService" since HLS suggested a case issue with caps.
<service-point id="cryptoService" interface="common.crypto.ICrypto"/>
<implementation service-id="cryptoService">
<create-instance class="common.crypto.CryptoService "/>
</implementation>
No luck,
Any suggestions?
Thanks in advance

Is this object supposed to be a "state" object or a "service" object? It's
called a service, but you're trying to use it as an ASO (application state
object). This is somewhat of a Tapestry question and should go to the
tapestry user list, but I'm familiar enough with Tapestry to help you I
think. Since you're using tap 4.1.x, you can just create a service point
(the website docs cover this) for your CryptoService interface and Tapestry
will automatically inject (or "autowire") it into your components/pages by
just declaring this:
public abstract CryptoService getCryptoService();

Folks,
My CryptoService adheres to my own unique interface. So I have no need to
associate or latch onto anything HLS created.
But I did try to bootstrap it into hivemind as an ASO
<contribution configuration-id=" tapestry.state.ApplicationObjects">
<state-object name="cryptoService" scope="application">
<create-instance class="common.crypto.CryptoService"/>
</state-object>
</contribution>
but upon operating my annotation in java
@InjectState("cryptoService")
public abstract CryptoService getCryptoService();
The thing quits with an exception stating that the object was not formatted
[ +/- ] Exception: Error: An error occured processing annotation
@ org.apache.tapestry.annotations.InjectObject(value=cryptoService) of
public
abstract common.crypto.CryptoService proto.Login.getCryptoService(): Error:
Object provider selector 'cryptoService' is not properly formatted.
But then I found other hivemind threads that talk about HiveUtils saying
that there is no way to treat any pojo like above and we should be doing
this...
<contribution configuration-id=" hiveutils.ObjectBuilderObjects">
<object name="CryptoService" cached="true"
class="common.crypto.CryptoService">
<inject name="entityService" object="service:EntityService" />
</object>
</contribution>
<contribution configuration-id=" tapestry.state.ApplicationObjects">
<state-object name="cryptoService" scope="application">
<invoke-factory object="object:CryptoService" />
</state-object>
</contribution>
But that failed due to non-existent config id of some sort...
Can anyone tell me how to get my basic pojo+unique interface into hivemind?
Using tap-4.1.1
Thanks in advance
Best regards
Ken
