Is anyone using this tool? I would be quite convenient for me as I am new to HQL. If I could get it to work that is...

I have my mapped classes showing up fine and everything seems OK with the configuration but whenever I try to execute my HQL (*any* HQL, however simple) I get:

java.lang.NoClassDefFoundError: javax/transaction/Synchronization
at net.sf.hibernate.impl.SessionFactoryImpl.openSession(SessionFactoryImpl.java:312)
at net.sf.hibernate.impl.SessionFactoryImpl.openSession(SessionFactoryImpl.java:325)
at net.sf.hibernate.impl.SessionFactoryImpl.openSession(SessionFactoryImpl.java:333)
at net.sf.hibern8ide.Hibern8IDE$ExecuteQuery.actionPerformed(Hibern8IDE.java:679

I've checked and this Class isn't even part of J2SE1.4.1 (which I am using).

I've got the required jars in my Classpath (Hibernate2.jar and the pf-joi-full.jar).

Am I still missing something?

Add the JTA jar from the hibernate distribution.

Thanks. That worked fine!

So I still need the JTA jar even though I never specified anything JTA related in my hibernate.properties? Or is that a Hibern8IDE requirement...

/Jonas

I forgot. I had an additional question:

Do you know if there is any way to automatically configure Hibern8IDE with the correct properties and hbm.xml files on startup? Like supplying program parameters. It's a drag to have to open dialogs and add the files every time you start the application...

I can't find anything about that on the tools homepage..

/Jonas

I forget who it was but it has been done and I understand the patch will be reviewed. Keep an sys out for the CVS changes.

I use Hibern8IDE from eclipse and the following program to start configured Hibern8IDE.

package com.test;

import net.sf.hibern8ide.Hibern8IDE;
import net.sf.hibernate.cfg.Configuration;

public class StartHibern8IDE {

public static void main(String[] args) throws Exception {
Configuration configuration = new Configuration();
configuration.configure();

Hibern8IDE.startWith(configuration);
}
}

Put hibernate.cfg.xml, mappings in the class path and put <mapping resource=""/> statements in the cfg file.

Can use this until you get the func. with Hibern8IDE.

Yes, see the ./lib/readme.txt in the hibernate distribution to find required jars

From readme:



That explains why I did not miss it when running from Tomcat :)

Thanks again emmanuel

g1friend:

Thanks for the code! I'm gonna try it.

Does anyone know if it's possible to set up the mappings in hibernate.properties and move that into the classpath instead of the cgf.xml file? I.e configuring the sessionfactory exclusively in .properties specifically for running ouside the container.

Since I have the JNDI Datasource defined in my .xml file I don't want to have to edit that out every time I start the Hibern8IDE since I get an stack when leaving it in and running outside the container...

/Jonas

I would suggest you run Hibern8IDE from the environment you want to test in ;)

just use the code posted earlier about starting Hibern8IDE with it's startWith(configuration) method - which allows you to explore hibernate from within an application server context.

As per http://hibernate.sourceforge.net/hibern ... on-2.0.dtd, the hibernate.cfg.xml should contain atleast one <mapping> element (The content of element type "session-factory" must match "(property*,mapping+,(class-cache|collection-cache|jcs-class-cache|jcs-collection-cache)*)".). So put one mapping resource in it which you think will normally not change and load the other mapping resources like this from the code (ofcourse you need to put these all the mapping files in the classpath).

package com.test;

import java.net.URL;

import net.sf.hibern8ide.Hibern8IDE;
import net.sf.hibernate.cfg.Configuration;

public class StartHibern8IDE {

public static void main(String[] args) throws Exception {
Configuration configuration = new Configuration();
configuration.addURL(new URL("file:///c:/test3.hbm.xml"));
configuration.configure();

Hibern8IDE.startWith(configuration);
}
}



You also have the other ways to load the mappings using Configuration (addResource(), addClass(), etc)

Hmm. Doesn't that mean I have to start it from a servlet or something? Even if I configure it to use my ANT settings and run it from there I am still not running in the container...

Crap. I really need to look at integrating IDEA better with Tomcat... I haven't had the energy so far since I use a version (4.1.29) that is not supported by the version of IDEA I am using (3.04).

/Jonas

starting from a servlet would be a good option - the easist way IMHO

Hello!

Integrating Hibern8IDE with BeanShell = new feature is...

For example: BeanShell textarea where we can create new persistent
objects etc. and use powerful interactive scripting facilities.
http://www.beanshell.org/

eh - Hibern8IDE already has that feature ;)
