having basic problems getting to first check point with ejb3 - just starting out and got stuck.
running europa eclipse and run JBOSS AS4.2 and have deployed a mysql JTA datasource in the server and started in Eclipse. Then I have created an EJB project and decalred an peristence unit xml as follows | <?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="embedDS" transaction-type="JTA"> | <provider>org.hibernate.ejb.HibernatePersistence</provider> | <jta-data-source>jdbc/embedDS</jta-data-source> | <class>org.model.Message</class> | <properties> | <property name="hibernate.hbm2ddl.auto" value="create-drop"/> | <property name="hibernate.show_sql" value="true"/> | </properties> | </persistence-unit> | </persistence> | I think i have this right - the defaultDS is still using jboss AS defaults. I then create simple message persistence entity class as follows. | package org.model; | | import javax.persistence.Column; | import javax.persistence.Entity; | import javax.persistence.GeneratedValue; | import javax.persistence.GenerationType; | import javax.persistence.Id; | import javax.persistence.*; | | @Entity | @Table(name="message", catalog="embed") | public class Message | { | private long messageID; | private String message; | | @Id | @GeneratedValue(strategy=GenerationType.AUTO) | @Column(name="messageID") | public long getMessageID() { | return messageID; | } | | public void setMessageID(long messageID) { | this.messageID = messageID; | } | | public String getMessage() { | return message; | } | | public void setMessage(String message) { | this.message = message; | } | | | | } | however in my eclipse editor this wont compile - the error says anonymous wrote : | Severity and Description Path Resource Location Creation Time Id | Schema "root" cannot be resolved for table "message" SessionTest/ejbModule/org/model Message.java line 11 1189118136216 1813 | | Severity and Description Path Resource Location Creation Time Id | Column "messageID" cannot be resolved SessionTest/ejbModule/org/model Message.java line 19 1189118136216 1811 | | and | | Severity and Description Path Resource Location Creation Time Id | Column "message" cannot be resolved SessionTest/ejbModule/org/model Message.java line 28 1189118136216 1812 | | - cant therefore compile nor test the rest of my understanding if i cant get past this. the error Schema "root" cannot be resolved for table "message" is associated with the @table annotation - any ideas as what I am doing wrong here ?
