Re: [ANNOUNCE] Wicketopia 0.9 Released...
James,
I am a new user of wicketopia :) I tried your cool tool and I got the NPE
error. I am not sure what else need to be configured for Spring to inject
PersistenceProvider. It might not be injected due to something I need to
setup in the Spring applicationContext?
Would you mind sharing the xml file or throw some light?
Thanks.
My codes -
package wicket.pages;
import org.apache.wicket.markup.html.WebPage;
import org.apache.wicket.markup.html.basic.Label;
import org.apache.wicket.model.Model;
import org.apache.wicket.spring.injection.annot.SpringBean;
import org.wicketopia.persistence.PersistenceProvider;
import org.wicketopia.persistence.component.scaffold.Scaffold;
import com.appspot.cloudserviceapi.media.xmm.Movies;
public class HomePage extends WebPage {
@SpringBean
private PersistenceProvider persistenceProvider;
public HomePage() {
add(new Label("message", new Model("Hello World!")));
add(new Scaffold<Movies>("scaffold", Movies.class,
persistenceProvider));
}
}
The NPE is -
Unexpected RuntimeException

wicket.pages.HomePage()

Turned out to be sqlite3 pagination issue, nothing to do with Wicketopia.
Issue resolved! Thus, verified that Wicketopia 0.9.2 all good.
Please let me know if you still need any help in maintaining the project.
Thanks!

Try using the @Enabled annotation to limit editing to only certain
"contexts" (such as ADMIN or something).

James,
Your metadata annotation is based on Metastopheles, but I can't find much
information about it. Do you have more information elsewhere that you could
provide?
Specifically, I need to see if there is a way to make a property "read only"
(non-editable). What kind of annotation should I apply in the domain class?
Thanks.
AG

I fixed all the issues over the weekend.
If you like, I can send you the changes as I don't have commit access to the
project.
There is still slight issues though, it seems like navigation/paging is not
working correctly if there are more than 1000 records.

More good news. I used JPA provider instead of hibernate by looking at your
latest codes to make Wicketopia works on GAEJ.
Also have to change the JpaPersistenceProvider in such a way -
public int getCount(Class<?> entityType)
{
Integer results = (Integer) entityManager.createQuery("select
count(obj) from " + entityType.getName() + " obj").getSingleResult();
return results.intValue();
// List results = entityManager.createQuery("select count(*) from " +
entityType.getName()).getResultList();
// return ((Number)results.get(0)).intValue();
}
I left off at the create method while saving the Person. Error is -
java.lang.UnsupportedOperationException: This feature isn't available until
JPA 2.0
You can try yourself at http://cloudserviceapi.appspot.com/app/ to see the
error. Note that I removed some fields like start date and end date as they
were on my way to complete the "port" :(
I have proven my track record, could you make me a committer of project
Wicketopia now :) ?

I am working on making it works on GAE/J. But stuck at
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="org.vnetcon.blobdb.driver.jdbc.BlobDBDriver" /> <property name="url" value="blobdb|http://localhost:8888/blobdb/ws|username=username|password=password" /> <property name="username" value="sa" /> <property name="password" value="" /></bean>
And the partial error -
WARNING: Could not obtain connection to query metadatajava.sql.SQLException: URL is not in the correct format: blobdb|http://localhost:8888/blobdb/ws|username=username|password=password at com.google.cloud.sql.jdbc.internal.Exceptions.driverUrlNotInCorrectFormat(Exceptions.java:103) at com.google.cloud.sql.jdbc.Driver.connect(Driver.java:47) at com.google.cloud.sql.jdbc.Driver.connect(Driver.java:24) at java.sql.DriverManager.getConnection(DriverManager.java:582) at java.sql.DriverManager.getConnection(DriverManager.java:154) at org.springframework.jdbc.datasource.DriverManagerDataSource.getConnectionFromDriverManager(DriverManagerDataSource.java:173)
I posted the error with GAE forum :)
Will let you know how it goes.

Ok after some struggling, I managed to get it work. I noticed that Wicketopia
has a tight coupling with Hibernate, especially -
<bean id="persistenceProvider"
class="org.wicketopia.persistence.hibernate.HibernatePersistenceProvider">
<property name="sessionFactory" ref="sessionFactory"/>
</bean>
And the codes needs sessionFactory to be initialized (not null), in order to
work. That was why I were having NPE.
Is there any plan to support Google App Engine for Java? I can help out if
you can give me some guidelines.
Thanks for such an awesome framework!
