This part of the appendix lists XML schemas related to integration technologies.
The jee
tags deal with Java EE (Java Enterprise Edition)-related configuration issues,
such as looking up a JNDI object and defining EJB references.
To use the tags in the jee
schema, you need to have the following preamble at the top
of your Spring XML configuration file; the text in the following snippet references the
correct schema so that the tags in the jee
namespace are available to you.

The jms
tags deal with configuring JMS-related beans such as Spring’s
MessageListenerContainers. These tags are detailed in the
section of the JMS chapter entitled JMS namespace support. Please do consult that chapter for full details on this support
and the jms
tags themselves.
In the interest of completeness, to use the tags in the jms
schema, you need to have
the following preamble at the top of your Spring XML configuration file; the text in the
following snippet references the correct schema so that the tags in the jms
namespace
are available to you.
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:jms="http://www.springframework.org/schema/jms" xsi:schemaLocation="

This element is detailed in Configuring annotation based MBean export.
The cache
tags can be used to enable support for Spring’s @CacheEvict
, @CachePut
and @Caching
annotations. It it also supports declarative XML-based caching. See
Enable caching annotations and
Declarative XML-based caching for details.
To use the tags in the cache
schema, you need to have the following preamble at the
top of your Spring XML configuration file; the text in the following snippet references
the correct schema so that the tags in the cache
namespace are available to you.
