Can I use property placeholders in Jetty-env.xml? - spring

Question

I am working on a project that uses jetty-env.xml to define some resources in the test environment. It requires that I hijack it and put in my username and password for the resources. Is there a way to define my credentials in an external way and use a property placeholder instead? Like in the Spring applicationConfig.xml I can use ${username} as defined in my system properties.
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE Configure PUBLIC "-//Mort Bay Consulting//DTD Configure//EN" "http://jetty.mortbay.org/configure.dtd">
<Configure id="wac" class="org.mortbay.jetty.webapp.WebAppContext">
<New id="validation_mail" class="org.mortbay.jetty.plus.naming.Resource">

<Set name="properties">

</New>
</Set>

</Arg>

<Set name="serverName">testip.example.edu:2025</Set>
<Set name="portNumber">2025</Set>
<Set name="user">username</Set> <!-- put username here -->
<Set name="password">password</Set> <!-- put password here -->
</New>

I new to these tools so I might be closer to an answer than I think. Any help would be appreciated.
Enviroment:
Spring Tool Suite 3.4.0 RELEASE
Maven 3
Jetty Plugin 6.1

Answer 1

If you're using the jetty maven plugin, then you can define your properties in a properties file.
Configure the jetty plugin like this:
<configuration>
<systemPropertiesFile>${project.basedir}/src/test/conf/jetty-env.properties</systemPropertiesFile>
</configuration>
And then your jetty-env.xml can be like this:
<New id="dsDatasource" class="org.eclipse.jetty.plus.jndi.Resource">
<Arg>jdbc/dsProtWb</Arg>
<Arg>
<New class="org.apache.commons.dbcp.BasicDataSource">
<Set name="driverClassName">net.sourceforge.jtds.jdbc.Driver</Set>
<Set name='url'>jdbc:jtds:sqlserver://ROPFDN812Q:4900/dlmp_proteomics_wb_dev;instance=FDNDEV18;domain=mfad</Set>
<Set name="username"><SystemProperty name="LANID" /></Set>
<Set name="password"><SystemProperty name="LANPW" /></Set>
</New>
</Arg>
</New>

Answer 2

You can define environment variables and use the Env tag as a placeholder.
<New id="dsDatasource" class="org.eclipse.jetty.plus.jndi.Resource">
<Arg>jdbc/dsProtWb</Arg>
<Arg>
<New class="org.apache.commons.dbcp.BasicDataSource">
<Set name="driverClassName">net.sourceforge.jtds.jdbc.Driver</Set>
<Set name='url'>jdbc:jtds:sqlserver://ROPFDN812Q:4900/dlmp_proteomics_wb_dev;instance=FDNDEV18;domain=mfad</Set>
<Set name="username"><Env name="LANID"/></Set>
<Set name="password"><Env name="LANPW"/></Set>
</New>
</Arg>
</New>
