This artifact provides a single jar that contains all classes required to use remote EJB and JMS, including all dependencies. It is intended for use by those not using maven, maven users should just import the EJB and JMS BOM's instead (shaded JAR's cause lots of problems with maven, as it is very easy to inadvertently end up with different versions on classes on the class path).

There is a newer version: 34.0.0.Final

/**
 * Route which forwards all messages to a given site via a given route.

 * Example: if site HF is reachable via NET1, and NET2 is not directly connected to HF, it needs to have a
 * ForwardConfig with to="HF" and gateway="NET1". This means that a message to site HF will be forwarded to NET1,
 * which then forwards it to HF.

 * Note that 'to' can be a regular expression and {@link #matches(String)} can be used to match a given site against it.
