Yes excatly. You can define multiple froms in a single camel context
and each JMS listener is their own dedicated worker thread.
If using Spring DSL just add multiple <route> elements
<camelContext>
<route>
<from uri="x">
<to uri="xxx">
</route>
<route>
<from uri="y">
<to uri="yyy">
</route>
</camelContext>
In Java DSL you can just add multiple from in the same route builder
configure() method
public void configure() {
from(x).to(xxx);
from(y).to(yyy);
}
