No registered metadata for type "class "
Hi all , I am a newbie of openjpa , and using openjpa to run on
geronimo, coding using eclipse
I face a runtime error sounds
>>>> Caused by: java.lang.Exception: java.lang.IllegalStateException:
No registered metadata for type "class
com.quesofttech.entity.Material".
where "Material" is a class name of my EntityBean ,
com.quesofttech.entity is the package name.
I have search the google , and understand that it may caused by
configuration problem, in persistence.xml and orm.xm, however, I still
cannot figure out what is the problem. l
my orm.xml is plain with no entity mapping.
orm.xml
=======
<?xml version="1.0" encoding="UTF-8"?>
<entity-mappings xmlns="http://java.sun.com/xml/ns/persistence/orm"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence/orm
http://java.sun.com/xml/ns/persistence/orm_1_0.xsd" version="1.0">
</entity-mappings>
Here is the persistence.xml for the reference
======================
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="1.0"
xmlns="http://java.sun.com/xml/ns/persistence"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence
http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">
<persistence-unit name="EJBStructsEJB">
<description>Entity Beans for Material</description>
<provider>org.apache.openjpa.persistence.PersistenceProviderImpl</provider>
<jta-data-source>mysql</jta-data-source>
<class>com.quesofttech.entity.MaterialType</class>
<class>com.quesofttech.entity.Material</class>
<properties>
<property name="openjpa.jdbc.SynchronizeMappings" value="false"/>
<property name="openjpa.ConnectionDriverName"
value="com.mysql.jdbc.Driver"/>
<property name="openjpa.ConnectionURL"
value="jdbc:mysql:localhost:3306/ERP"/>
<property name="openjpa.ConnectionUserName" value="root"/>
<property name="openjpa.ConnectionPassword" value="xxxxxx"/>
</properties>
</persistence-unit>
</persistence>
May I know what is the function and purpose of persistence.xml and orm.xml for ?
my understanding is , orm.xml is for entitybean and databases mapping
(table and field) , and persistence.xml is to define which entitybean
suppose to be persistent. Is it correct ?
Any help is appreciated , thanks.

Hi David,
I have settled this problem with your suggestion plus some reference
to old msg in this mailing list
I do not sure which steps that I took that solve this problem but I
follow all the below steps still does not work , I finally try a few
other steps and at the end , adding <non-jta-data-source> tag in
persistence.xml solve my problem.
Thanks for your help.

I'm not sure if these relate to the problem you are seeing but...
1. remove orm.xml
2. remove the properties setting up the database driver from
persistence.xml and rely on the jta-datasource
3. make sure both Material and MaterialType have appropriate
annotations to show it is a persistent bean.
thanks

Initially feel that it should be openjpa question , so sent to openjpa
user mailing list. However, seems like it is not active. Therefore,
forward it to geronimo mailing list to get some help .
