Hi,
i tried this.
I added this in hivemodule.xml:
<contribution configuration-id="tapestry.state.ApplicationObjects">
<state-object name="globalObject" scope="application">
<create-instance class="my.package.Global"/>
</state-object>
</contribution>
<service-point id="Resource"
interface="org.apache.tapestry.engine.IEngineService">
<invoke-factory>
<construct class="ResourceService">
<set-object property="sharedResourceProvider"
value="aso:shared-resource-provider"/>
</construct>
</invoke-factory>
</service-point>
<contribution configuration-id="hivemind.ObjectProviders">
<provider prefix="aso" service-id="ApplicationStateObjectProvider"/>
</contribution>
<service-point id="ApplicationStateObjectProvider"
interface="org.apache.hivemind.service.ObjectProvider">
<invoke-factory>
<construct class="my.package.MyApplicationStateObjectProvider">
<set-object property="applicationStateManager"
value="infrastructure:applicationStateManager"/>
</construct>
</invoke-factory>
</service-point>
The MyApplicationStateObjectProvider is exactly like your class.
How can i access from a Service to the GlobalObject?
When i try:
cycle.getInfrastructure().getApplicationStateManager().exists("globalObject");
then i get a "false"! what is wrong?
Best regards

Here is an example of creating ApplicationStateObjectProvider which allows
you to inject ASOs via "aso" prefix, for instance:
<service-point id="Resource"
interface="org.apache.tapestry.engine.IEngineService">
<invoke-factory>
<construct class="ResourceService">
<set-object property="sharedResourceProvider"
value="aso:shared-resource-provider"/>
</construct>
</invoke-factory>
</service-point>
In order to do this we need to define an "aso" prefix for Application State
Objects. We can do it like this in the hivemodule.xml:
<contribution configuration-id="hivemind.ObjectProviders">
<provider prefix="aso" service-id="ApplicationStateObjectProvider"/>
</contribution>
<service-point id="ApplicationStateObjectProvider"
interface="org.apache.hivemind.service.ObjectProvider">
An object provider based on Application State Objects
<invoke-factory>
<construct class="ApplicationStateObjectProvider">
<set-object property="applicationStateManager"
value="infrastructure:applicationStateManager"/>
</construct>
</invoke-factory>
</service-point>
Here we creating an object provider service that will manage ASOs via
applicationStateManager. In fact we are injecting applicationStateManager
into it. Here is an example of the ApplicationStateObjectProvider class:
package org.keyintegrity.servicehub.csulengine.engine.state;
import org.apache.hivemind.Location;
import org.apache.hivemind.internal.Module;
import org.apache.hivemind.service.ObjectProvider;
import org.apache.tapestry.engine.state.ApplicationStateManager;
public class ApplicationStateObjectProvider implements ObjectProvider {
private ApplicationStateManager applicationStateManager;
public Object provideObject(Module contributingModule, Class
propertyType,
String locator, Location location) {
return applicationStateManager.get(locator);
}
public void setApplicationStateManager(ApplicationStateManager
applicationStateManager) {
this.applicationStateManager = applicationStateManager;
}
}
Thats all. Hope this will help.

Hello,
injecting an ASO into a page or component is simple, but I cannot
figure out how to inject one into a service. Can anyone tell me
what to do?
Thanke
Regards, Christian
P.S.: Injecting the ApplicationStateManager and obtaining the state
object from the it by name works fine, but this is not very direct.
