OK, thanks to the SVN links, I see I need to reference the service by the Java class of the interface, not by the id which I assigned to that service). Very curious and I either missed that in the docs or (once again?) it's not documented.
I swear, back in Tap2.0 I was an evangelist, but at this point using Tapestry feels like coding by braille or utter trial and error. Is that just me or is there some hard to find great docs that everyone else has read? If so, please, please pass along the link.

I'm not (yet) using autowire (nor Tap4.1) so how does one reference something in a page? I'm trying to use an annotation but it's not working. Here are some details: <html-snippet file="View.html"> <p><span jwcid="@Insert" value="ognl:date">Monday</span></p> <p><span jwcid="@Insert" value="ognl:jndiServiceString">jndi info</span></p> </html-snippet> <java-snippet file="View.java"> import java.util.Date; import org.apache.hivemind.lib.NameLookup; import org.apache.tapestry.annotations.InjectObject; import org.apache.tapestry.html.BasePage; public abstract class View extends BasePage { @InjectObject("service:jndiLookup") public abstract NameLookup getJndiLookupService(); // This blows chunks. public String getJndiServiceString() { return getJndiLookupService().toString(); } // This works public String getDate() { return (new Date()).toString(); } } </java-snippet> <xml-snippet file="hivemodule.xml"> <?xml version="1.0"?> <module id="CustomTeamPageAdmin" version="1.0.0"> <service-point id="jndiLookup" interface="org.apache.hivemind.lib.NameLookup" parameters-occurs="none"> <invoke-factory service-id="hivemind.BuilderFactory" model="singleton"> <construct class="org.apache.hivemind.lib.impl.NameLookupImpl"> <set property="initialFactory" value="org.jnp.interfaces.NamingContextFactory" /> <set property="URLPackages" value="org.jboss.naming:org.jnp.interfaces" /> <set property="providerURL" value="jnp://localhost:1099" /> <set-service property="coordinator" service-id="RemoteExceptionCoordinator" /> <event-listener service-id="RemoteExceptionCoordinator" /> </construct> </invoke-factory> </service-point> </module> </xml-snippet> The hivemodule.xml is in the WEB-INF folder and is being found and parsed (I know, because I initially left out the version attribute and saw an exception in the JBoss logs). The above doesn't work. Am I referencing the hivemind stuff the wrong way? using the annotation incorrectly? HiveMind is completely silent on the subject (nothing in the JBoss logs or the page) what I see is: <output-snippet> org.apache.tapestry.BindingException Unable to read OGNL expression '<parsed OGNL expression>' of [EMAIL PROTECTED]: jndiServiceString binding ExpressionBinding[View jndiServiceString] location context:/View.html, line 11 6 7 <div jwcid="@For" source="ognl:list" value="ognl:item"> 8 <span jwcid="@Insert" value="ognl:item" /><br /> 9 </div> 10 11 <p><span jwcid="@Insert" value="ognl:jndiServiceString">jndi info</span></p> 12 13 </body> 14 </html> org.apache.hivemind.ApplicationRuntimeException Unable to read OGNL expression '<parsed OGNL expression>' of [EMAIL PROTECTED]: jndiServiceString component [EMAIL PROTECTED] location context:/View.html ognl.OgnlException jndiServiceString java.lang.AbstractMethodError amazon.pizza.portal.tapestry.pages.View.getJndiLookupService()Lorg/apache/hivemind/lib/NameLookup; * amazon.pizza.portal.tapestry.pages.View.getJndiServiceString(View.java:21) * sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) * sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) * sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) * java.lang.reflect.Method.invoke(Method.java:585) * ognl.OgnlRuntime.invokeMethod(OgnlRuntime.java:491) </output-snippet> Which, thanks to the vaunted "line-precise error reporting," tells me exactly what I already knew and very little about what's causing the issue. Hence this post.... Any help appreciated. BTW, I can't for the best Google query I can construct, find a simple example of accessing a JNDI object via HiveMind and using it in Tapestry page or component. I'd think this would be a canonical example. I find plenty with Spring, of course, ...

Interface-based services are preferred. Anyway, if you have to use a bean, all you have to do is use the bean class as the interface when defining your service. You can set your "parameters" by autowiring (if they're supposed to be references to other HiveMind services) or using XML inside the hivemodule.xml file. If you're using tapestry-autowire (or Tap4.1), then all you have to do is declare an abstract getter of the same type as your bean class and Tapestry will automatically look it up for you. -----Original Message----- From: Epstein, Ezra [mailto:[EMAIL PROTECTED] Sent: Tuesday, July 11, 2006 3:12 PM To: Tapestry users Subject: General HiveMind questions So I've got an object I want to make available to a Tapestry page and I want to use HiveMind to do this. What are the steps one takes? More specifically: the object does *not* implement an interface; the object has parameters (set via mutator methods). (Maybe should be posted on the HiveMind lists) Thanks, Ezra Epstein --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
