org.apache.naming.java
public class: javaURLContextFactory [javadoc | source]

java.lang.Object
   org.apache.naming.java.javaURLContextFactory

All Implemented Interfaces:
InitialContextFactory, ObjectFactory

Context factory for the "java:" namespace.

Important note : This factory MUST be associated with the "java" URL prefix, which can be done by either :

Adding a java.naming.factory.url.pkgs=org.apache.catalina.util.naming property to the JNDI properties file
Setting an environment variable named Context.URL_PKG_PREFIXES with its value including the org.apache.catalina.util.naming package name. More detail about this can be found in the JNDI documentation : javax.naming.spi.NamingManager#getURLContext(java.lang.String, java.util.Hashtable) .
