Meta-Data - JDOConfig

JDO allows you to define a file jdoconfig.xml that specifies the properties for a named PMF. As always with XML, the metadata must match the defined DTD/XSD for that file type. This section describes the content of the jdoconfig files. All jdoconfig files must contain a valid DTD/DOCTYPE specification. You can use PUBLIC or SYSTEM versions of these.

Here are a few examples valid for jdoconfig files with DTD specifications

<!DOCTYPE jdoconfig PUBLIC
    "-//The Apache Software Foundation//DTD Java Data Objects Configuration 3.2//EN"

<!DOCTYPE jdoconfig SYSTEM "file:/javax/jdo/jdoconfig.dtd">

Here is an example valid for jdoconfig files with XSD specification

<?xml version="1.0" encoding="UTF-8" ?>
<jdoconfig xmlns=""
    xsi:schemaLocation="" version="3.2">

Your MetaData should match either the DTD or the XSD specification.
