I am very new to Hibernate and trying to work through several examples.

Hibernate version:3.1

Mapping documents:
<hibernate-mapping>
<class name="com.hibernate.test.Honey" table="honey">

<meta attribute="session-method">
HibernateUtil.getSession();
</meta>
<id name="id" column="honeyId" type="java.lang.Integer">
<!-- postgre:
<generate class="sequence">
<param name="sequence">honey_id_seq</param>
</generate>
-->
<generator class="native"/>
</id>
<property name="name" column="honeyName" type="java.lang.String" />
<property name="taste" column="taste" type="java.lang.String" />
</class>
</hibernate-mapping>


Code between sessionFactory.openSession() and session.close():

Full stack trace of any exception that occurs:

Name and version of the database you are using:MQSQL

When I change to the Hibernate perspective in Eclipse 3.2, I can see the configuration file for the project. However, when I right click on the configuration file and select "generate Session Factory, I get the above stacktrace. For some reason, the mapping file can not be found. However, the mapping file is in the same directory as the hibernate.cgf.xml file.

What am I doing wrong? Can someone please point me in the right direction?

Thank you in advance for any possible suggestions.


Russ

you need to put the build path into the classpath of the console configuration

Max:

Thank you for responding. I apologizenot understanding, but I don't understand the terms you are using. I understand the build path;this is part of project's properties in eclipse. The classpath is part of the buildpath under the windows preferences. What I don't understand is the console configuration. Can you explain more, please?

I apologize for not understanding. I am very next to Hibernate.

Russ

you have already created a console configuration - otherwise you would not be able to get the above exception.

Double click the console configuration you are trying to create a session factory for and a dialog should popup where you can add paths to the console configuration classpath.

Thanks Max! I found the console configuration. Thanks for explaining it so I could understand.

What I did was add the mapping file location to the mapping portion within the console. I also added to the classpath the project root and the location of the source files (src).

Now I am getting a NPE when I try to generate a Session Factory.

What am I doing wrong?

Thanks for reading my post........


Russ

either use a newer version of the tools where this bug should not be present anymore or separate your classes and src into different directories.

Max:

Sorry I have not responded as I have been away.

I have the src and bin directories established for the project. When I click on create sessionfactory or expand the Hibernate configuration tree for the project, I get the below exceptions:

As far as the current versions are concern, I've download the lastest tool plugin I am using the JBOSS version JBossIDE-1.5RC2-ALL. I am led to believe I have all the latest information and versions.

Can you be more specific on what I could check to validate the configuration?


As always, thanks for your time in reading my post.


Russ

i'm quite sure this is fixed in the latest version which is in the nightly builds now and will be released soon.

Max:

Thanks for responding.

Can you give me a timeframe on how long it will be before we have another release? I would hate to go through the pain of trying to build the nightly changes when the release is just around the corner.

Russ

within days/weeks.

But remember that if we didn't have helpfull users checking out the nightly builds they would not report issues in jira so we could fix them - so using nightly builds to see if your "favorite" bug is fixed/remains is the best way to ensure that the final one will be better..
