Hi What's your persistence.xml look like? <-- Here it it: (as per the JPA integration instruction)?
<?xml version="1.0" encoding="UTF-8"?> <persistence xmlns="http://java.sun.com/xml/ns/persistence"; version="2.0"> <persistence-unit name="DemoUnit" transaction-type="RESOURCE_LOCAL"> <properties> <property name="javax.persistence.jdbc.driver" value="org.h2.Driver" /> <property name="javax.persistence.jdbc.url" value="jdbc:h2:mem:test" /> <property name="javax.persistence.jdbc.username" value="sa" /> <property name="eclipselink.ddl-generation" value="create-tables"/> <property name="eclipselink.logging.level" value="fine"/> </properties> </persistence-unit> </persistence> Where exactly should the persistence.xml file be located? In the doc it says: "and is expected to be located on the classpath in the * META-INF* directory." Is that under the WEB-INF directory? Do you get login messages int he logs for EclipseLink? <-- No. What are the contents of your WEB-INF/lib? <-- There is no lib older under WEB-INF in my sample app? AppModule.java? <-- Here is it (much the same as in the Hibernate / Tutorial sample app). (I didn't add any of the configuration code mentioned in the JPA instructions as I understood this was needed only in XML-less JPA configuration package com.example.jpa.services; import java.io.IOException; import org.apache.tapestry5.*; import org.apache.tapestry5.ioc.Configuration; import org.apache.tapestry5.ioc.MappedConfiguration; import org.apache.tapestry5.ioc.OrderedConfiguration; import org.apache.tapestry5.ioc.ServiceBinder; import org.apache.tapestry5.ioc.annotations.Contribute; import org.apache.tapestry5.ioc.annotations.Local; import org.apache.tapestry5.services.Request; import org.apache.tapestry5.services.RequestFilter; import org.apache.tapestry5.services.RequestHandler; import org.apache.tapestry5.services.Response; import org.slf4j.Logger; /** * This module is automatically included as part of the Tapestry IoC Registry, it's a good place to * configure and extend Tapestry, or to place your own service definitions. */ public class AppModule { public static void bind(ServiceBinder binder) { // binder.bind(MyServiceInterface.class, MyServiceImpl.class); // Make bind() calls on the binder object to define most IoC services. // Use service builder methods (example below) when the implementation // is provided inline, or requires more initialization than simply // invoking the constructor. } public static void contributeApplicationDefaults( MappedConfiguration<String, String> configuration) { // Contributions to ApplicationDefaults will override any contributions to // FactoryDefaults (with the same key). Here we're restricting the supported // locales to just "en" (English). As you add localised message catalogs and other assets, // you can extend this list of locales (it's a comma separated series of locale names; // the first locale name is the default when there's no reasonable match). configuration.add(SymbolConstants.SUPPORTED_LOCALES, "en"); // The factory default is true but during the early stages of an application // overriding to false is a good idea. In addition, this is often overridden // on the command line as -Dtapestry.production-mode=false configuration.add(SymbolConstants.PRODUCTION_MODE, "false"); // The application version number is incorprated into URLs for some // assets.

The interface, * RequestFilter, is used within the RequestHandler service pipeline, which is built from the * RequestHandler service configuration.

When you chain multiple filters together, each filter // received a handler that is a bridge to the next filter. return handler.service(request, response); } finally { long elapsed = System.currentTimeMillis() - startTime; log.info(String.format("Request time: %d ms", elapsed)); } } }; } /** * This is a contribution to the RequestHandler service configuration. This is how we extend * Tapestry using the timing filter. A common use for this kind of filter is transaction * management or security. The @Local annotation selects the desired service by type, but only * from the same module. Without @Local, there would be an error due to the other service(s) * that implement RequestFilter (defined in other modules). */ public void contributeRequestHandler(OrderedConfiguration<RequestFilter> configuration, @Local RequestFilter filter) { // Each contribution to an ordered configuration has a name, When necessary, you may // set constraints to precisely control the invocation order of the contributed filter // within the pipeline. configuration.add("Timing", filter); } } On Wed, Aug 10, 2011 at 7:34 PM, Lenny Primak <lpri...@hope.nyc.ny.us>wrote: > I think your issue is environmental.
