Hi,
I'm new to JBoss and facing this problem presently.
I've created a simple EJB3/JPA app and using jboss-4.2.2.GA and Derby embedded. Here
is what I have in the following files:
persistence.xml:
| <?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="Monitor">
| <provider>org.hibernate.ejb.HibernatePersistence</provider>
| <jta-data-source>jdbc/jndi-name</jta-data-source>
| <mapping-file>/META-INF/orm.xml</mapping-file>
|
|
| <properties>
| <property name="hibernate.show_sql" value="true" />
| <property name="hibernate.format_sql" value="true" />
|
| <property name="hibernate.dialect"
| value="org.hibernate.dialect.DerbyDialect" />
| <property name="hibernate.hbm2ddl.auto" value="create"
/>
| </properties>
|
| </persistence-unit>
| </persistence>
|
I have the following TestClient
|
| package testcases;
|
| import java.util.Properties;
|
| import javax.naming.InitialContext;
|
| import session.Monitor;
|
|
| public class TestClient {
|
| Monitor bean = null;
|
| public void runTest() throws Exception {
| InitialContext ctx = new InitialContext();
| bean = (Monitor) ctx.lookup("OSMonitorSateless/remote");
|
| System.out.println("Searching ejb/OSMonitorSateless...");
|
| <some other initialization code goes here.....
| ..........................
| .............................................>
|
| System.out.println("Creating ejb/OSMonitorSateless...");
| bean.create(snmp.getId(), o, c, i, m, s, snmp.getIn(), snmp.getR(),
| snmp.getB());
| bean.toString();
| }
|
| public static void main(String[] args) {
| try {
| TestClient cli = new TestClient();
| System.out.println("Created Class...");
| cli.runTest();
|
| } catch (Exception e) {
| e.printStackTrace();
| }
| }
|
| }
|
Now whenever I try to run the example, I get the following error:
| - Could not find datasource: jdbc/jndi-name
| javax.naming.NoInitialContextException: Need to specify class name in environment or
system property, or as an applet parameter, or in an application resource file:

I have also defined the derby-ds.xml, and it looks like the following:
| <?xml version="1.0" encoding="UTF-8"?>
|
| <datasources>
| <local-tx-datasource>
| <jndi-name>jndi-name</jndi-name>
| <use-java-context>false</use-java-context>
| <connection-url>
| jdbc:derby:C:/JPATest/dataDB
| </connection-url>
| <driver-class>
| org.apache.derby.jdbc.EmbeddedDriver
| </driver-class>
| <user-name>xyzzz</user-name>
| <password>xyzzz</password>
| <exception-sorter-class-name>
| org.jboss.resource.adapter.jdbc.vendor.MySQLExceptionSorter
| </exception-sorter-class-name>
| </local-tx-datasource>
| </datasources>
|
Do I need to add need some more xml files in the project?
Will appreciate a lot if somebody can help.
-Thanks,
James.
