hi all,
i have written a web app that uses jdo.
i have written a class named Test in the package com.marco.test
i have placed the Test.jdo in the same package, and then created a jar file.
i have subsequently added the jar file to the lib directory of the web application.
the Test.jdo class is as follow
<?xml version="1.0" encoding="UTF-8"?>
<jdo>
<package name="com.tgmm.commons">
<class name="Test" objectid-class="java.lang.Integer">
<field name="name">
<extension vendor-name="jboss" key="column-name" value="name"/>
</field>
<field name="te�" default-fetch-group="true">
<extension vendor-name="jboss" key="column-name" value="tel"/>
</field>
<extension vendor-name="jboss" key="table-name" value="test"/>
<extension vendor-name="jboss" key="objectid-column-name" value="oid"/>
<extension vendor-name="jboss" key="datasource" value="java:/MySqlDS"/>
<extension vendor-name="jboss" key="key-generator-factory"
value="java:/HiLoIDGeneratorFactory"/>
</class>
</package>
<extension vendor-name="jboss" key="persistence-manager-factory"
value="java:/PersistenceManagerFactory"/>
</jdo>
in the code i am trying to retrieve the PersistenceManagerFactory by doing this:
InitialContext ic = null;
try {
ic = new InitialContext();
pmf =
(PersistenceManagerFactory)ic.lookup("java:/PersistenceManagerFactory");
System.err.println("We got successfully
persistencemanagerfactory.");
} catch(NamingException e) {
e.printStackTrace();
}
but i keep on getting following exception.
