The local registry acts as a memory registry where you can store text strings, XML strings, and URLs. These entries can be retrieved from a mediator.
WSO2 ESB allows to add, edit and delete local registry entries easily.

Local Registry/Local Entries

The <localEntry> element is used to declare registry entries that are local to the ESB instance as shown below:

<localEntry key="string" src="url">text | xml</localEntry>

These entries are top level entries which are globally visible within the entire system. Values of these entries can be retrieved via the extension XPath function synapse:get-property(prop-name) and the keys of these entries could be specified wherever a registry key is expected within the configuration.

An entry can be static text specified as inline text or static XML specified as an inline XML fragment or specified as a URL (using the src attribute). A local entry shadows any entry with the same name from a remote Registry.

<localEntry key="version">0.1</localEntry>
<localEntry key="validate_schema">
   <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" ...
   </xs:schema>
</localEntry>
<localEntry key="xslt-key-req" src="file:repository/samples/resources/transform/transform.xslt"/>

Local entries can be defined in the top level synapse.xml file or in the synapse-config/local-entries directory.
