When the include processing instruction is used, the contents of the file specified are read and inserted into the configuration tree at the location where the include tag was specified.

<?xml version="1.0" encoding="UTF-8"?>
<config xmlns="urn:com.cohga.server.config#1.0"...
<?include client_main.xml?>
</config>
|
the client_main.xml file could contain
| Code Block |
|---|
|
<?xml version="1.0" encoding="UTF-8"?>
<config xmlns="urn:com.cohga.server.config#1.0" xmlns:client="urn:com.cohga.html.client#1.0">
<client:config id="main">
<default>true</default>
<debug>false</debug>
<theme>grey</theme>
...
</client:config>
</config>

The set instruction can supplement the include instruction by providing support for variable substitution within the configuration file.
A variation on the previous example can be used when only the hostname needs to change between the development and production servers, so this time config.xml could contain
| Code Block |
|---|
|
<?xml version="1.0" encoding="UTF-8"?>
<config xmlns="urn:com.cohga.server.config#1.0"...
<jdbc:dataSource id="datasource.main">
<driver>oracle.jdbc.driver.OracleDriver</driver>
<url><![CDATA[jdbc:oracle:thin:@${HOSTNAME}:1521:GIS]]></url>
<username>reader</username>
<password>0hn0w3rdun</password>
<pool:pool>
<maxActive>15</maxActive>
<minIdle>2</minIdle>
<maxIdle>2</maxIdle>
<testOnBorrow>true</testOnBorrow>
<timeBetweenEvictionRunsMillis>60000</timeBetweenEvictionRunsMillis>
<minEvictableIdleTimeMillis>1200000</minEvictableIdleTimeMillis>
<whenExhaustedAction>grow</whenExhaustedAction>
</pool:pool>
</jdbc:dataSource>
</config>
|
Then the datasource.xml file on the development server could contain
| Code Block |
|---|
|
<?set HOSTNAME=development.example.com?>
|
and the datasource.xml file on the production server could contain
| Code Block |
|---|
|
<?set HOSTNAME=production.example.com?>
