Re: Hibernate Search Fix

This would also work (and would only happen at most once per request:

@Scope(ScopeConstants.PERTHREAD)
public static FullTextSession buildFullTextSession(HibernateSessionManager
sessionManager) {
return Search.getFullTextSession(sessionManager.getSession());
}

Re: Hibernate Search Fix

Seems like it's caused by your jvm's security and accessing a private class.

This should work (less verbose too):

public static FullTextSession buildFullTextSession(
final HibernateSessionManager sessionManager,
PropertyShadowBuilder propertyShadowBuilder)
{
Object lazyBuilder = new Object() {
public FullTextSession getFullTextSession() {
return
Search.getFullTextSession(sessionManager.getSession());
}
};
return propertyShadowBuilder.build(lazyBuilder, "fullTextSession",
FullTextSession.class);
}

Hi, Lance Java offered the following snippet of code back in

http://apache-tapestry-mailing-list-archives.1045711.n5.nabble.com/grid-dont-link-hibernate-classic-session-td5669885.html

-- 
You could add this to your app module:

private static class LazyFullTextSession {
private HibernateSessionManager sessionManager;

public LazyFullTextSession(HibernateSessionManager sessionManager)
{
this.sessionManager = sessionManager;
}

public FullTextSession getFullTextSession() {
return
Search.getFullTextSession(sessionManager.getSession());
}
}

public static FullTextSession
buildFullTextSession(HibernateSessionManager sessionManager,
PropertyShadowBuilder propertyShadowBuilder)

{

//Seems to be failing on this line
LazyFullTextSession lazy = new LazyFullTextSession(sessionManager);
return propertyShadowBuilder.build(lazy, "fullTextSession",
FullTextSession.class);
}

I'm seeing the following exception and wondering what might be causing it.
I"m using 5.4.22

Interesting...thanks, Lance.  Probably improves performance in search results
page loading.

You could add this to your app module:

private static class LazyFullTextSession {
private HibernateSessionManager sessionManager;

public LazyFullTextSession(HibernateSessionManager sessionManager)
{
this.sessionManager = sessionManager;
}

public FullTextSession getFullTextSession() {
return
Search.getFullTextSession(sessionManager.getSession());
}
}

public static FullTextSession
buildFullTextSession(HibernateSessionManager sessionManager,
PropertyShadowBuilder propertyShadowBuilder)

{
LazyFullTextSession lazy = new LazyFullTextSession(sessionManager);
return propertyShadowBuilder.build(lazy, "fullTextSession",
FullTextSession.class);
}

Then in you component / page, you could @Inject FullTextSession.

Hibernate Search Fix

[netdawg]

Yep.  That was it...Tapestry Hibernate Session needs work to play nice within
FullTextSession. 

Workaround is in thread below: 

http://tapestry.1045711.n5.nabble.com/Hibernate-Search-td4446040.html

Also, JIRA already open...

https://issues.apache.org/jira/browse/TAP5-1178

I would add 

1.  Hibernate-Lucene search is one of the hottest (or coolest!) thing out
... this would be a priority 
2.  (and/or) disambiguate session generated by services as a tapestry
creation...to perhaps avoid the confusion.  

Basically, I did this...

1.  First inject the HibernateSessionManager just like you would Session.  

import org.apache.tapestry5.hibernate.HibernateSessionManager;
import org.hibernate.Session;

@Inject
private Session session;
@Inject
private HibernateSessionManager sessionManager;

2.  Use it to get the session (and not wrap just the plain old
session)...the session may be used elsewhere to do usual CRUD, not hibernate
search


FullTextSession fullTextSession =
Search.getFullTextSession(sessionManager.getSession()); 

// instead of 
// FullTextSession fullTextSession = Search.getFullTextSession(session);
