If you try to use Camel without Spring using code something like this
CamelContext context = new DefaultCamelContext(); context.addRoutes(new MyRouteBuilder()); context.start();You might get an exception like this
[java] Caused by: javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial [java] at javax.naming.spi.NamingManager.getInitialContext(NamingManager.java:645) [java] at javax.naming.InitialContext.getDefaultInitCtx(InitialContext.java:247) [java] at javax.naming.InitialContext.getURLOrDefaultInitCtx(InitialContext.java:284) [java] at javax.naming.InitialContext.lookup(InitialContext.java:351) [java] at org.apache.camel.impl.JndiRegistry.lookup(JndiRegistry.java:51)This is because if you are not using Spring then the default Registry implementation uses JNDI .
A simple workaround for this is to specify a JNDI provider. An easy fix is to create a file called jndi.properties on the classpath and give it this content...
java.naming.factory.initial = org.apache.camel.util.jndi.CamelInitialContextFactory
