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. CG
