is it possible to set the value and access in context.xml in tomcat7 like JNDI?

I would like to set some values in context.xml file and access the same from my Servlet like we access in JNDI:

mail.smtp.host=smtp.gmail.com
mail.smtp.port=465

Can I do this?

Solution

  • Yes its absolutely possible

    <Environment name="testEnvEntry" value="Got It"
         type="java.lang.String" override="false"/>

    Then access this like:

    Object lookedUp = null;
try {
    InitialContext initialContext = new InitialContext();
    lookedUp = initialContext.lookup("java:/comp/env/testEnvEntry");
} catch (NamingException e) {
    e.printStackTrace();
}

    It is similar to how you would add <env-entry> in your web.xml.
